The fracture screw 755 includes a protection member (a storage member 754) for covering at least a part of the separation part 755D in a state before the fracture screw 755 is fractured. A guide part (a fracture screw loading part 766H) for guiding a shaft part 757 of the fracture screw 755 to a screwing position (a screw hole 767P of a fracture screw screwing part 767) is arranged in a place (a fracture screw put-through part 766) where the one structural member (the outer case 70M) is fastened with the use of the fracture screw 755.

Description

  The present invention relates to gaming machines represented by pachinko machines and slot machines.

  In a gaming machine such as a pachinko machine using a pachinko ball, for example, for the purpose of obtaining an illegal profit, for example, a control board such as a main control board that controls the game is illegally removed and a ROM (CPU In the case where the ROM is made into one chip, an illegal act such as exchanging the chip) and changing the game content may be performed.

  For this reason, the board box containing the control board is closed with a special screw called a breaking screw, or the board box is attached to a predetermined position with the breaking screw, thereby preventing illegal acts. It has been made to prevent. The breaking screw has a configuration in which a small-diameter breaking portion is formed in the middle portion of the head, and after screwing into the screw hole with a screwdriver and fastening it, when rotated with a larger torque, the breaking screw is located on the tip side from the breaking portion. The part having the screw hole for inserting the screwdriver is broken and separated, so that the screw cannot be subsequently loosened by rotating it backward. By using this breaking screw for closing or attaching the substrate box, it is difficult to open or remove the substrate box, and therefore, illegal acts can be effectively prevented.

However, since the rupture screw as described above is formed with a rupture portion that is easy to rupture, for example, especially during being placed in a large amount in one place before fastening work,
There is a risk that the rupture portion will be broken by receiving some external force and become unusable as a screw before being used for fastening (hereinafter, this situation is also referred to as “false break”).

  Therefore, a holder is previously mounted on the head of the breaking screw as a protective member that covers it. According to this configuration, even when a certain external force is applied before the fastening operation, the head of the fracture screw is protected from the external force by the holder, thereby effectively preventing the fracture screw from being erroneously broken. In addition, after breaking the head of the breaking screw, the separated part becomes garbage, and it is necessary to dispose of it, or the separated part enters other parts of the gaming machine and causes trouble. However, if this separated part is held by a holder, these problems can be avoided.

JP 2010-42070 A

  However, in addition to the erroneous rupture before the fastening operation as described above, for example, during the fastening operation of the rupture screw, particularly when the shaft portion of the rupture screw is screwed into the screw hole, it is accurately placed on the central axis of the screw hole If it is difficult to screw in while holding the shaft part of the breaking screw so that it is positioned, and if the shaft part of the breaking screw is going to be screwed in a state shifted from the center axis of the screw hole If an abnormal external force that is biased toward the head of the breaking screw is transmitted, erroneous breakage will occur.

  The present invention has been devised in view of such problems, and in a gaming machine using a broken screw, a gaming machine capable of reducing the erroneous breakage of the broken screw and performing the fastening operation more reliably. The purpose is to provide.

In order to achieve the above object, the gaming machine according to the present invention
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by screws,
The screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.
The component member has a guide portion that guides a shaft portion of the screw to a screwing position at a place fastened by the screw,
The guide portion has a peripheral wall shape, the screw is screwed in a state where the protection member is surrounded by the guide portion, and a solidified material is injected and solidified between the protection member and the guide portion. It is characterized by.

  According to the configuration of the present invention, when the shaft portion is screwed into the screw hole during the fastening operation of the breaking screw, the shaft portion is guided to the screwing position by the guide portion, so that the shaft portion is displaced. It is possible to accurately screw the screw into the screwing position with no posture, so that the broken screw can be screwed in a state in which an abnormal external force biased to the head is difficult to be transmitted and erroneous breakage is unlikely to occur.

  According to the present invention, when two or more gaming machine components are fastened and connected with the breaking screws, the fastening operation can be reliably performed without erroneously breaking the breaking screws.

  Hereinafter, embodiments of a gaming machine according to the present invention will be described with reference to the drawings. In the following embodiments, a pachinko machine will be described for the sake of convenience. However, the present invention uses a ball ball game machine other than the pachinko machine (for example, an arrange ball machine, a sparrow ball game machine, etc.), and other game balls. The present invention can be applied to various types of gaming machines.

(Front configuration of pachinko machine)
FIG. 1 is a front view of a pachinko machine 10 according to the present embodiment, FIG. 2 is a left side view of the pachinko machine 10, and FIG. 3 is a plan view thereof. FIG. 4 is a perspective view showing a state in which the inner frame 12, the front frame (set) 14, and the set plate 400 are opened with respect to the outer frame 11. (However, in FIG. 4, for the sake of convenience, the configuration in the game castle on the surface of the game board 30 (nail, center accessory, etc.) is shown blank, but the out port 36 is drawn).

As shown in FIGS. 1 to 4, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be openable and closable. I have. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of light metal such as resin or aluminum in order to reduce the weight.
The opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side of the game ball launching handle 18 (left side of the pachinko machine 10 in FIG. 1) as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the axis as the center. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  The lower plate unit 13 is fixed to the front frame base member as a part of the front frame set 14. On the front side of the lower tray unit 13, a lower tray 15, a ball release lever 17, a game ball launching handle 18, and an ashtray 22 are provided, and sound output ports 24 are provided at the left and right upper end positions of the inner frame 12. ing. The lower tray 15 serving as a ball receiving tray is provided at a substantially central portion of the lower tray unit 13 and serves to stop a game ball discharged from the outlet 16 when the upper tray 19 described later becomes full. There is. The ball removal lever 17 is for removing a game ball in the lower plate 15. By moving the ball removal lever 17 to the left in FIG. 1, a predetermined position on the bottom surface of the lower plate 15 is opened, The game ball stopped in the tray 15 can be discharged through the opening on the bottom surface of the lower tray 15 to the player's ball storage box (dollar box).

  The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launch handle 18 by the player, the game ball is driven toward the game board 30 by the game ball launch device 38 (see FIG. 4). The game ball launcher 38 includes a game ball launch handle 18, a set handle, a launch motor, and the like, which will be described later. The sound output port 24 is an output port for outputting sound from a speaker provided at the position of the upper left and right ends of the inner frame 12. Moreover, the ashtray 22 is provided on the left side of the lower tray 15 as shown in FIG. The ashtray 22 is supported so as to rotate (for example, forwardly toward the front side) about an axis line in the left-right direction (horizontal direction).

As shown in FIG. 4, the front frame 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame 14 has an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened forward with the heart. Moreover, the front frame 14 is attached so as to fit into the outer wall (rib) 12B of the inner frame 12.
That is, since at least a part of the side surface of the front frame 14 is attached so as to fit into the outer wall (rib) 12B of the inner frame 12, foreign matter (needle-like shape) is formed from the gap between the inner frame 12 and the front frame 14. Or, it is a thin plate or the like, and specifically, it is possible to prevent illegal acts such as inserting a wire, a piano wire, a celluloid plate, etc.). Further, since the front frame 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, the front frame 14 is highly viscous and resistant to impact, and can be manufactured at low cost.

  On the other hand, an upper plate 19 (see FIG. 1) as a receiving tray for game balls is provided integrally with the front frame 14 at a lower portion of the front frame 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line.

  As shown in FIG. 4, the inner frame 12 is mainly configured by a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20. A game board 30 shown in FIGS. 4 and 5 is detachably mounted on the rear side of the resin base 20. As shown in FIG. 5, the game board 30 is made of a rectangular plywood, one upper corner is shouldered (described later), and its peripheral edge abuts on the back side of the resin base 20 (inner frame 12). It has been installed in the state.

  Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20 (FIG. 4 shows an out port 36 of the game board 30). ing). And here, a corner (corner) close to a pivoting portion of the game board 30 with respect to the outer frame 11 of the inner frame 12 (a pivoting centering on an opening / closing axis extending vertically to the left side when viewed from the front of the pachinko machine 10). However, as shown in FIG. 5, the corner is dropped (notched) 720 in a substantially triangular shape.

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 5 is a front view showing the configuration of the game board 30. Two pairs of general winning ports 31, 31 are arranged in a stepped manner at a slightly lower position on the left and right of the game board 30, and a starting port 33 is arranged at the lower center. The general winning ports 31, 31 and the starting port 33 are openings that penetrate from the game area toward the back surface, and a winning device is attached to correspond to these openings. That is, a ball detection sensor corresponding to these is provided on the back surface of the game board 30, and these sensors are connected to a main control board (main control device) to be described later through an electric wiring (not shown). .
When a game ball enters the general winning openings 31, 31 and the start opening 33, it is detected by the detection sensors, and based on the output of the detection sensors, the upper plate 19 (or the lower plate 15). When a predetermined number of prize balls are paid out and a game ball enters the start port 33, a lottery to be described later is started.

The detection results detected by the winning sensor are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is paid out from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board.
In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

  In addition, a decorative symbol display device 42 using a liquid crystal panel is disposed at the center of the game board 30, and through gates 34, 34 are disposed on the left and right side portions thereof. These through gates open and close the wings of the starting port 33 described later by passing the game ball. In addition, a decorative member 35 having the above-described general winning ports 31 and 31 is provided at the lower left and right positions of the game board 30, and an out port 36 is provided at the lower part of the game board 30. A game ball that has not entered the apparatus or the like is guided through the out port 36 toward a ball discharge path (not shown) on the back of the game board 30. Further, the game board 30 is provided with a large number of guide nails for appropriately dispersing and adjusting the falling direction of the game balls, and a windmill having the same function.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. .

In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of a game ball. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51.
In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 5). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 5: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner side surface of the outer rail 52, a sliding plate as a long metal strip made of stainless steel is attached to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is worn.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30.

A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and serves to guide the foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage. .
Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 5) such as certificate stamps (for example, serial numbers are described) and plates. In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 5) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said. Therefore, when it is referred to as a game area, the guide rail portion is not included, and the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail 52.

  In the resin base, below the window hole 21 (game board 30), a launch rail for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. The launch rail is fixedly attached to the resin base via a metal plate behind the launch rail, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail, and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It has come to be.

  Further, there is a gap of a predetermined interval between the launch rail and the rail unit 50 (guidance rail), and a foul ball passage is formed below this gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 15 to the lower plate 15. To be discharged.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. There is also a thing that jumps to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage. As a result, all of the foul balls are reliably guided to the foul ball passage. Interference between the ball and the next-launched game ball is suppressed.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame 14 side (ball outlet leading from the most downstream portion of the upper plate 19). Further, the game ball launching device 38 is provided with a ball striking ball, and the game ball is launched with the rotation of the ball striking center around the shaft portion.

  A reference numeral 67 in FIG. 4 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / closable shutter that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction, and has a state in which the front frame 14 is opened from the inner frame 12.

  As shown in FIG. 19, when the cover member 501 is closed and brought into contact with the ball assembly plate 460, the edge of the peripheral wall portion 515 </ b> C of the fracture screw insertion portion 515 is also brought into contact with the ball assembly plate 460. The entire screw portion 463 is surrounded by the peripheral wall portion 515C. In this state, the breaking screw 522 is inserted into the breaking screw insertion portion 515 from the back side (the cover member 501 side) and screwed into the screwing portion 463, whereby the cover member 501 is fixed to the ball assembly plate 460. As will be described later, the breaking screw 522 is rotated at a predetermined high torque, whereby the separation portion on the tip side of the head is broken and separated. In this state, the breaking screw 522 cannot be rotated by the driver, and the breaking screw 522 is surrounded by the peripheral wall portion 515C of the breaking screw insertion portion 515. Therefore, the breaking screw 522 cannot be removed without leaving a trace. Impossible. As a result, the cover member 501 and the ball assembly plate 460 are sealed. On the other hand, by cutting the cutting portion 515A, the sealing state of the cover member 501 and the ball assembly plate 460 can be released while leaving a trace.

  As described above, the free end of the cover member 501 has a generally U-shaped shape in front view in which the band portion forming the middle step is inwardly inserted, but the upper and lower protruding portions sandwiching the indented portion. The first sealing portion 520A is provided on each of the front end surfaces. Further, a break screw insertion portion 516 is provided at a position above the first sealing portion 520A on the tip surface of the lower protruding portion. The breaking screw insertion portion 516 has a configuration having upper and lower extending pieces (including a peripheral wall portion) and a bottom wall substantially the same as the breaking screw insertion portion 515 provided on the bottom plate of the indented portion.

  Further, as shown in FIG. 15, a screw-in portion 464 is provided at a position corresponding to the breaking screw insertion portion 516 provided in the lower protruding portion of the cover member 501 in the ball assembly plate 460. Similarly to the screwing portion 463, 464 is formed in a cylindrical shape extending to the back side (the cover member 501 side), and a screw groove is provided therein so that the breaking screw 522 can be screwed therein. Yes. The second sealing portion 520B shown in this embodiment includes upper and lower breaking screw insertion portions 515 provided on the bottom plate of the indented portion of the cover member 501, a breaking screw insertion portion 516 provided on the protruding portion, and these breaking screws. Screwed portions 463 and 464 provided in the ball assembly plate 460 so as to correspond to the insertion portions 515 and 516, cutting portions 515A and 516A provided in the respective broken screw insertion portions 515 and 516, and a broken screw 522 The cover member 501 and the ball assembly plate 460 can be sealed at three points arranged in the height direction.

  The upper and lower broken screw insertion portions 515 provided on the bottom plate of the indented portion of the cover member 501 are sandwiched between the upper and lower support portions 413A of the bracket 413 in the opening / closing mechanism 410, as shown in FIGS. The space between these support portions 413A is substantially closed, and is close to the head of a rivet that is a shaft 411 that pivotally attaches the first control board box 201A.

  As shown in FIG. 9 to FIG. 11 and FIG. 21, the fixed end portion (the right end portion in FIG. 9, FIG. 11 and FIG. 21) on the outer surface (side surface of the first control board box 201A) of the cover member 501 A rectangular locking piece 517 with a locking claw formed at the tip is disposed so as to protrude rearward (to the first control board box 201A side), while the inner case 85 of the first control board box 201A A rectangular protrusion 851 is disposed on the free end so as to protrude laterally (to the right in FIG. 21), and the locking piece 517 is formed on the protrusion 851 as shown in FIG. It can be elastically locked. The locking piece 517 is integrally formed with the cover member 501.

  Further, as shown in FIG. 11, a rectangular recess 518 is formed in the free end portion on the outer surface of the cover member 501. The rectangular recess 518 has a length (length along the longitudinal direction of the cover member 501) and a depth substantially equal to the length (about 48 mm) and thickness (about 13 mm) of the connection mounting base member 430, respectively. As shown in FIG. 9, the coupling mounting base member 430 can be accommodated in the interior with almost no gap, and the outer side surface (open side surface) of the coupling mounting base member 430 and the outer side surface of the cover member 501 in the accommodated state. Is supposed to be the same. This prevents a gap from being formed as much as possible between the first control board box 201A.

(Partial modification of cover member)
As shown in FIG. 23, the number of ribs formed inside the cover member 501 may be reduced. In the example shown in FIG. 23, the formation of ribs is significantly less than in the case of the above embodiment, and the number of compartments corresponding to this is reduced. Further, ribs may not be formed inside the cover member 501, and the internal space may not be partitioned, or an appropriate material may be filled inside the cover member to substantially eliminate the internal space. Also good.

  Further, in the example shown in FIG. 23, three breaking screw accommodating portions 521 for accommodating the breaking screws 522 for the second sealing portion 520B are formed on the wall surface in the cover member 501 here, and there are One breaking screw 522 is set for each. As a result, each time the cover member 501 is unsealed and released, the breaking screw is taken out one by one and inserted and screwed into the three breaking screw insertion portions 515 and 516 of the second sealing portion 520B. The unused breaking screw 522 can be securely held inside the cover member 501 in a sealed state. For example, the breaking screw accommodating portion 521 may be configured to accommodate only one breaking screw, and in this case, the breaking screw can be held inside the cover member when not in use.

  Further, in the pachinko machine 10, sealing means constituted by the first and second sealing portions 520A and 520B is provided at one end portion of the cover member 501 and the position of the ball assembly plate 460 corresponding thereto. Although the structure is the same, the same or different sealing means may be provided at the other end portion, thereby fixing both ends of the cover member 501 in a sealed state. In this case, sealing means may be further provided at an end portion of the cover member 501 provided with an opening / closing structure (a structure that is pivotally supported), but both end portions are fixed by the sealing means. The open / close structure can be omitted.

  In the pachinko machine 10, the cover member 501 is provided so as to cover the back surface of the ball assembly plate 460 on the back surface of the game board 30, so that the relay board, wiring, etc. disposed on the back surface of the ball assembly plate 460 are provided. The electric parts can be protected, and the electric parts can be prevented from being broken or disconnected due to the assembly of other electric parts or the contact of other parts from the outside. That is, in assembling the pachinko machine 10, for example, electrical components such as a relay board, LED board, switch, and wiring are attached to the ball assembly plate 460, and a cover member 501 is attached to the ball assembly plate 460 to form a unit. Then, if this unit is attached to the game board 30 and then the first control board unit 201 is attached, the workability is improved. In such a case, at least a part of the electrical components is also covered by the cover member 501. By being covered with the cover, the electrical component is protected by the cover member 501, and the electrical component is prevented from being damaged during the mounting operation.

In addition, a gap between the back surface of the game board 30 and the first control board unit 201 is compensated, so that a space for performing an illegal act is not formed.
Furthermore, since this cover member 501 is fixed in a state of being sealed by the sealing means 520, it is difficult to remove it illegally, and even if this seal is illegally broken, there is no trace. Since it remains, it is obvious at a glance that the seal has been broken, which makes it easy to detect fraud.

  Further, the sealing means includes a first sealing portion 520A and a second sealing portion 520B, and the first sealing portion 520A is inserted into the ball assembly plate 460 from the game board 30 side so that the cover member 501 is sphered. Screws 519 which are fixing means for fixing to the collective plate 460, a recess 465 provided on the bottom plate with a hole provided on the game board 30 side of the ball collective plate 460, and a screw 519 provided on the cover member 501. The ball assembly plate 460 is attached to the game board 30 because the insertion portion 514 is inserted and fixed, and the cutting portion 514A is provided in the insertion portion 514 to release the fixed state by the screw 519. In this state, it is impossible to remove the screw 519 from the outside. As a result, the cover member 501 is fixed in a sealed state, and if it is illegally removed without leaving any trace, It becomes necessary to remove the set plate 460 from the game board 30, thus making it difficult to carry out the fraud. On the other hand, for example, when the cover member 501 is opened for the purpose of inspecting the back side of the ball assembly plate 460, the sealing state of the cover member 501 can be released while leaving a trace by cutting the cutting portion 514A. Further, when the ball assembly plate 460 is not attached to the game board 30, the cover member 501 can be freely opened, so that workability is good.

  Furthermore, the second sealing portion 520B is inserted into the cover member 501 from the back side, and a break screw 522 that fixes the cover member 501 to the ball assembly plate 460, and a hole provided in the cover member 501 through which the break screw 522 is inserted. Breaking screw insertion portions 515 and 516 having a bottom plate, screw insertion portions 463 and 464 provided on the ball assembly plate 460 into which the breaking screws 522 are screwed, and a breaking screw insertion portion for releasing the fixed state by the breaking screws 522 The cover member 501 can be fixed to the spherical assembly plate 460 from the outside by the breaking screw 522, and thus the cover member 501 can be easily fixed. It can be fixed in a sealed state. At this time, even when the ball assembly plate 460 is attached to the game board 30, the cover member 501 can be sealed and fixed to the ball assembly plate 460 from the outside by the breaking screw 522. After releasing the sealing state by the first sealing portion 520A, the cover member 501 and the ball assembly plate 460 can be sealed again by the second sealing portion 520B. On the other hand, when the cover member 501 is opened for the purpose of, for example, inspecting the back side of the ball assembly plate 460, the sealing state of the cover member 501 is released while leaving traces by cutting the cutting portions 515A and 516A. Can do.

  Furthermore, one end portion of the first control board unit 201 is pivotally attached by the shaft 411, and the breaking screw insertion portion 515 is close to the shaft 411 that pivotally attaches the first control board unit 201. Even if the first control board unit 201 is illegally removed from the pivoting portion, it is difficult to remove the pivoting portion due to the broken screw insertion portion 515 and the cover member 501 is sealed. Therefore, it is difficult to remove the breaking screw insertion portion 515 without leaving a trace even if it is attempted to remove the breaking screw insertion portion 515. Therefore, fraud is more effectively prevented.

  Furthermore, a break screw accommodating portion 521 that accommodates one or more break screws 522 for the second sealing portion 520B is disposed inside the cover member 501, so that the break screw accommodating portion 521 has a break screw. If 522 is accommodated, every time the sealing of the cover member 501 is released and opened, the breaking screw 522 is taken out one by one and the next sealing is performed by the second sealing portion 520B. In the stage where there is an unused breaking screw 522, it can be securely held inside the cover member 501 in a sealed state.

  Furthermore, the first sealing portion 520A is provided in the corner portion of the cover member 501, and the second sealing portion 520B is provided in addition to the corner portion, so that the cover member 501 is cornered by the first sealing portion 520A. Thus, the cover member 501 can be sealed more easily and reliably by the second sealing portion 520B. In addition, since the first and second sealing portions are provided at a plurality of places, if sealing and releasing are performed at one place for each time of performing sealing and releasing, sealing and releasing are performed. This process can be performed a plurality of times, and an opening history can be left for each process.

  Further, since the cover member 501 is formed into a hollow body and the inside is partitioned into a number of chambers by the ribs 512, a sufficient space is provided in the cover member 501 to install an unauthorized substrate. Therefore, cheating can be effectively prevented.

  Furthermore, since the cover member 501 has a configuration in which the surface facing the ball assembly plate 460 is opened, the opened surface is also in contact with the ball assembly plate 460 when the cover member 501 is closed. For this reason, fraudulent acts such as installing an unauthorized substrate inside the cover member 501 are difficult. At this time, as described above, even if the inside of the cover member 501 is partitioned into a number of chambers by the ribs 512, if the open part of the cover member 501 is exposed to the outside, the ribs 512 are cut from the outside and the illegal action However, it is also difficult to cut the rib 512 by making the open surface of the cover member 501 face the spherical assembly plate 460 as described above.

  Furthermore, since the cover member 501 and the first control board unit 201 have an open / close structure that opens and closes in the opposite direction, the cover member 501 and the first control board unit 201 are opened. Is not concentrated on either one of the left and right ends, but is distributed on both the left and right ends. Therefore, for example, when the cover member 501 and the first control board unit 201 are opened for inspection or the like, a problem such as deformation of the spherical assembly plate 460 due to the load of the cover member 501 and the first control board unit 201 is prevented. The If the ball assembly plate 460 is deformed, there is a risk that the game balls may be discharged.

  Further, one end of the first control board unit 201 is pivotally attached to the shaft 411 and is locked to the cover member 501 to the other end (free end) of the first control board unit 201. By adopting a configuration in which the pieces are integrally molded, it is not necessary to separately prepare a member (for example, a ny latch) for holding the free end portion of the first control board unit 201, and the number of parts can be reduced. Further, if the cover member 501 is illegally removed, the free end portion of the first control board unit 201 is released without being held, so that an illegal act can be easily detected, and therefore illegal acts are performed. It becomes more difficult.

In the assembly of the pachinko machine 10, for example, electrical components such as a relay board, an LED board, a switch, and a wiring are attached to the ball assembly plate 460, and a cover member 501 is attached to the ball assembly plate 460 to configure them as a unit. If the unit is attached to the game board 30 and then the first control board unit 201 is attached, the workability is improved. In such a case, at least a part of the electrical components is covered by the cover member 501. By making it cover, an electrical component is protected by the cover member 501, and it is prevented that an electrical component is damaged at the time of an installation operation | work.
FIG. 22 shows a state in which the cover member 501 and the first control board unit 201 are attached to the sphere assembly plate 460. Thus, the sphere assembly plate 460, the cover member 501 and the first control board unit 201 are shown in FIG. A process of attaching 201 to the game board 30 in an integrated state is also possible, and the assembly method of the pachinko machine 10 is not limited to a specific one, but as described above, the game is performed with the ball assembly plate 460 and the cover member 501 as a unit. The workability of the process of attaching the first control board unit 201 after being attached to the panel 30 is particularly good.

(Feature configuration)
In the pachinko machine 10 according to the present embodiment, as described above, the first control board box 201A, which is a board box, is disposed on the back side of the game board 30, and the first connecting board base member 430 corresponding to the mounting board has the first control board box 201A. Breaking screws are used to connect and attach the control board box 201A. The first control board box 201A and the connection mounting base member 430 are provided with a first mounting base sealing part 450 and a second mounting base sealing part 432, respectively. The first control board box 201 </ b> A is connected and sealed to the connection mounting base member 430 by connecting and sealing the 2 mounting base sealing part 432 with the breaking screw 651.

  The breaking screw 651 is made of cold forging carbon steel wire (SWCH), and as shown in FIG. 24, is composed of a head portion 652 and a shaft portion 653, and the head portion 652 has a screw hole (not shown) on the tip surface. And the head body 655 are continuously formed so as to be arranged in the axial direction from the tip side in this order, and the shaft part 653 is formed from the head body 655. It is extended. Both the separation part 654 and the head body 655 are basically cylindrical, and the head body 655 has a larger diameter than the separation part 654. As a result, the diameter gradually decreases in a tapered shape, and a constricted narrow diameter portion 656 is formed.

  The separating portion 654 extends in a cylindrical shape from the distal end side, slightly increases in diameter at the end portion on the shaft portion side, and gradually decreases in diameter into a tapered shape as described above, whereby the cylindrical portion 654P And a tapered portion 654T, a flange portion 657 is formed.

  As shown in the partially enlarged view of FIG. 25, the shaft portion 653 has a configuration in which a notch 620 is formed in a screw thread 619. Each notch 620 is a square notch formed by notching a screw thread 619 in a substantially trapezoidal shape in plan view from the periphery, and is formed at four locations at regular intervals (every 90 °) in the circumferential direction of the screw thread 619. These four portions are formed so as to be aligned with each other in the axial direction of the shaft portion 653. When the breaking screw 651 is screwed into the first mounting base sealing portion 450, the resin that is the constituent material of the first mounting base sealing portion 450 bites into the notch 620, thereby effectively loosening the breaking screw 651. To be prevented.

  A housing member 621 shown in FIG. 24 is fitted to the head 652 of the breaking screw 651. The housing member 621 is made of sulfur free-cutting steel (SUM) and is a substantially cylindrical holder. An operation hole 622 having a diameter slightly larger than the diameter of the cylindrical portion 654P in the separation portion 654 of the breaking screw 651 and smaller than the outer diameter of the flange portion 657 is formed in one end surface portion of the housing member 621. Under the operation hole 622, a flange portion accommodating cavity 623 having a diameter larger than the outer diameter of the flange portion 657 and smaller than the outer diameter of the head body 655 is continuously formed. A head body housing cavity 624 having a diameter slightly larger than the outer diameter of the head body 655 is continuously formed below, whereby the inside of the housing member 621 is expanded stepwise from the operation hole 622. It has a shape of diameter.

  The distal end edge of the housing member 621 on the head body housing cavity 624 side has a shape that is slightly narrowed so that the outer diameter is slightly reduced, whereby a thin portion 625 is formed. In the present embodiment, the distal end edge of the housing member 621 on the head body housing cavity 624 side is thinned so as to reduce the outer periphery. However, as will be described later, in such a case, the thinning is performed by cutting. On the other hand, the portion 625 can be easily formed. On the other hand, it is possible to reduce the thickness by enlarging the inner periphery, but in such a case, the thin portion can be easily formed by header processing.

  A head 652 of a breaking screw 651 is inserted into the housing member 621 from the head body housing cavity 624 side, and thereafter, the thin portion 625 is pressed to the inside as shown in FIG. Deformation process to bend. Thus, an insertion hole 627 that extends inward from the edge of the peripheral wall on the side opposite to the operation hole 622 formation side toward the center of the housing member 621 and has a smaller hole diameter than the outer diameter of the head body 655 at the center. The formed latching portion 628 is formed. As described above, since the diameter of the operation hole 622 is smaller than the outer diameter of the flange portion 657 in the separation portion 654 of the breaking screw 651, the flange portion 657 is engaged with the periphery of the operation hole 622 and the head portion 652 of the breaking screw 651. However, the head main body 655 is engaged with the periphery of the insertion hole 627 of the latching portion 628 and the head 652 of the breaking screw 651 is extracted from the insertion hole 627 to the outside. Therefore, the head 652 of the breaking screw 651 is securely held in the state of being accommodated in the accommodating member 621. In this state, the head portion 652 of the breaking screw 651 is such that the cylindrical portion 654P of the separation portion 654 is fitted into the operation hole 622, and the tip surface on which a screw hole (not shown) is formed is exposed from the operation hole 622. It is held in a posture and is held rotatably in the housing member 621.

  When the accommodating member 621 is fitted to the breaking screw 651 as described above, the separation portion 654 is reliably protected by covering the head 652 of the breaking screw 651 with the accommodating member 621, thereby performing the fastening operation. Even when some external force is applied before the operation, erroneous breakage of the breaking screw 651 is effectively prevented.

  As shown in FIG. 26A, the breaking screw 651 fitted with the housing member 621 as described above is screwed into the screw hole (not shown) on the distal end surface of the head 652 exposed from the operation hole 622. Is inserted and rotated to be screwed into the first mounting base sealing portion 450 and the second mounting base sealing portion 432.

  At this time, since the head 652 of the breaking screw 651 is rotatably held in the housing member 621 as described above, the breaking screw 651 can be turned with the driver DR1 while gripping the housing member 621 from the outside. Easy screwing operation. That is, it is difficult to grip the housing member 621 from the outside in a state where the breaking screw 651 is almost housed inside the second mounting base sealing portion 432, but the housing member 621 is pinched in the previous stage. The breaker screw 651 can be turned by the driver DR1 while being held by the screwdriver, so that the screwing operation is easy. In other words, the housing member 621 also functions as a support (support) of the breaker screw 651 during the screwing operation. can do.

  In addition, the screw hole on the distal end surface of the separating portion 654 is held in a posture that is exposed from the operation hole 622 and is not covered with the housing member 621, and the head 652 of the breaking screw 651 is rotatably held in the housing member 621. Therefore, the driver DR1 can be engaged with the screw hole and the rotation operation can be performed even in a state where the housing member 621 is fitted. Therefore, the housing member 621 can be removed from the breaking screw 651 or the detached housing member 621 can be removed. It is possible to easily carry out the work without the need for extra handling such as handling separately.

  When the breaking screw 651 is screwed in until it is fastened (finally tightened), the resin constituting each of the first mounting base sealing portion 450 and the second mounting base sealing portion 432 is notched 620 in the shaft portion 653 of the breaking screw 651. As a result, the breaking screw 651 is prevented from loosening. Thereafter, when the motor is further rotated at a high torque, the head 652 of the breaking screw 651 is broken at the small diameter portion 656 and the separating portion 654 is separated from the head main body 655 as shown in FIG. .

  As described above, the separation portion 654 after separation is in a state where the flange portion 657 is engaged with the operation hole 622 and cannot be pulled out to the outside. Although it is held at a position between the main part 655 and the operation hole 622 of the accommodating member 621, the separating part 654 is accommodated with a certain margin (play), so that there is a slight movement in the accommodating member 621. Held in a possible state.

  The separation part 654 is reliably prevented from falling off by being covered with the housing member 621. In addition, since the separating portion 654 is separated, the head body 655 can no longer be loosened by being rotated backward by a driver. Further, at this time, for example, a pliers or the like is inserted from the outside through the operation hole 622 to grip the head main body 655, or a rod-like fraudulent tool is inserted to join the tip of the head main body 614 with an adhesive. Even if the head body 655 is forced to reversely rotate, the separated portion 654 after being separated is held at a position between the head body 655 of the breaking screw 651 and the operation hole 622 of the housing member 621. As a result, the separation part 654 becomes an obstacle, so that it is difficult for pliers and unauthorized tools to reach the head body from the outside, and therefore it is difficult to illegally release the connected state by the breaking screw 651. .

  At this time, in the state in which the housing member 621 is housed inside the second mounting base sealing portion 432, there is only a slight gap between the second mounting base sealing portion 432. It is difficult to turn the housing member 621 by inserting fingers or instruments from the outside of the mounting base sealing portion 432. If it is possible to turn the housing member 621, turning the housing member 621 may cause the breaking screw 651 to rotate therewith and release the fastening state.

  Further, since the separated portion 654 after being separated is held so as to be surrounded by the housing member 621, the separation portion 654 is reliably prevented from falling off, and the head body 655 is also reliably closed. It has been difficult for unauthorized operations from outside.

  Further, since the separation portion 654 after being separated is held in a posture fitted to the operation hole 622, the operation hole 622 is held in a closed state, so that the separation portion 654 functions reliably as an obstacle. It is possible to effectively prevent an unauthorized tool from approaching the head body 655 from the operation hole 622.

  Hereinafter, a process of manufacturing the housing member 621 shown in FIGS. 24 and 26 by header processing (forging forming) will be described.

  First, a coil material (wire material) made of a metal such as carbon steel is cut into a predetermined length, and a cylindrical metal material serving as a base of the housing member 621 is formed.

  After cutting, by applying pressure to the cylindrical metal material, the head body housing cavity 624, the flange section housing cavity 623, the thin wall section 625, and the operation hole 622 are formed in this order. In this case, it is possible to simultaneously mold these plural parts (molding by one press), but at the time of molding the thin part 625, there is a high possibility that cracking or the like will occur, so at least the thin part 625 It is preferable to mold by pressing at a low speed separately.

  In addition, when forming the thin part 625 by header processing, it is preferable to form in a step shape on the inner peripheral surface of the housing member 621. In this way, since the metal material can be easily held during pressurization, the thin-walled portion 625 can be easily formed as compared with the case where it is formed on the outer peripheral surface.

  Further, the thin portion 625 can be formed by cutting. In this case, it is preferable to form a stepped shape on the outer peripheral surface of the housing member 621. In this way, since the housing member 621 can be rotated and cut in a state where the tool is applied in the radial direction with respect to the outer peripheral surface of the housing member 621, the tool is compared with the case where the tool is formed on the inner peripheral surface. Can be easily arranged, and variation in the thickness of the thin portion 625 can be prevented. However, it is desirable that the thin-walled portion 625 gradually increase in thickness from the end portion (not a step but a curved surface) as in the present embodiment. In this case, the stress generated in each part can be made close to a certain level, and the thin portion 625 can be prevented from being damaged when the breaking screw 651 and the housing member 621 are integrated.

(Function)
As described above, in the pachinko machine 10 of the present embodiment, there is an engagement portion to which the driver DR1 that is an operation tool for performing the rotation operation is engaged, that is, a screw hole, and a torque that is larger than the torque required for fastening. A separating part 654, which is a part that can be broken and separated when rotated, can be connected to two constituent members, that is, the first control board box 201A and the connection mounting base member 430 by a break screw 651 formed on the head 652. In the configuration configured as described above, since the breaking screw 651 includes the housing member 621 as a protective member that covers a portion of the separation portion 654 other than the screw hole in a state before breaking, before the fastening operation is performed. Even if it receives some external force, the separation part 654 is protected from this external force by being covered with the accommodating member 621, thereby False breaking of cross screw 651 is adapted to be effectively prevented.

  In addition, since the screw hole of the separating portion 654 is not covered with the housing member 621, the driver DR1 can be engaged with the screw hole and rotated even when the housing member 621 is provided. It is possible to easily perform the operation without removing extra work such as removing the 621 from the breaking screw 651 or handling the removed housing member 621 separately.

  The head 652 of the breaking screw 651 is positioned between the separation portion 654, the head body 655 remaining on the shaft side after the separation portion 654 is separated, and the separation portion 654 and the head body 655. The separating portion 654 and the head main body 655 have a smaller diameter portion 656 than the head portion 655, and the separating portion 654 is separated by breaking at the smaller diameter portion 656. Since 621 covers at least the small-diameter portion 656, the small-diameter portion 656, which is a portion where the breaking screw 651 breaks, is reliably protected, and erroneous breakage of the breaking screw 651 is more effectively prevented. It is like that.

  Further, since the accommodating member 621 surrounds the entire portion of the separating portion 654 of the breaking screw 651 excluding the screw hole, the entire portion of the separating portion 654 other than the screw hole is more reliably protected from external force. Accordingly, erroneous breakage of the breaking screw 651 is further effectively prevented.

  In addition, the housing member 621 can hold the separation portion 654 of the breaking screw 651 after separation. When the fastening work is performed using a break screw, the separated separation part becomes garbage and the processing takes time and time, and the separation part enters from the gap in the gaming machine, and the clogging of the ball in the game ball passage Although there is a problem of causing a malfunction such as a short circuit of an electrical component, according to the configuration of the pachinko machine 10 of the present embodiment, the separating portion 654 of the breaking screw 651 after being separated is held by the housing member 621. As a result, the separation unit 654 does not become waste and does not require time and effort for processing, and it does not enter through the gap in the pachinko machine 10, thereby preventing problems.

In addition, the housing member 621 has a wall that covers the head 652 of the breaking screw 651 from the side operated by the driver DR1 (that is, the end surface wall on the operation hole 622 formation side), and the separation portion 654 cannot pass through the driver DR1. Since the separation portion 654 after the separation is provided at a position between the head body 655 of the breaking screw 651 and the operation hole 622, the separation portion after separation is provided. Since 654 is covered with the wall of the housing member 621, it is securely held and prevented from falling off.
Further, the head main body 655 in the head 652 of the breaking screw 651 after the separation part 654 has been separated cannot be loosened by rotating it backwards depending on the operating instrument such as the driver DR1. If it is open to the outside, the connected state may be illegally released by a forcible method such as joining a head-shaped unauthorized tool to the head body 655 from the outside with an adhesive and rotating it backward. However, according to the configuration of the pachinko machine 10 of the present embodiment, the separation portion 654 after separation is held at a position between the head body 655 and the operation hole 622 by the housing member 621, so that the separation is performed. Since the part 654 becomes an obstacle and the unauthorized tool cannot reach the head main body 655 from the outside, it is more reliably prevented that the connection state is illegally released.

  In addition, the housing member 621 has a head body housing cavity 624 as a first housing portion for housing the head body 655 of the breaking screw 651 in a state before breaking, and a flange portion as a second housing portion for housing the separation portion 654. And the separation portion 654 has a margin for allowing the head main body 655 to freely move in the axial direction and the radial direction within the head main body reception cavity 624 (first storage portion). It is equal to or smaller than the allowance for free movement in the axial direction and the radial direction in the second accommodating portion).

  Specifically, as shown in FIG. 27, when the breaking screw 651 is housed in the housing member 621, the tapered surface 655T of the head body 655 of the breaking screw 651 is the flange housing cavity 623 of the housing member 621. Can move in the head 652 side direction (upward in the figure, ie, in the direction of arrow A1) until it hits the edge (lower edge) on the head body housing cavity 624 side of the inner peripheral surface in FIG. As shown, the position where the tapered surface 655T hits the lower end edge of the inner peripheral surface of the flange housing cavity 623 is such that the head body 655 of the breaking screw 651 is the head body housing cavity 624 (first housing section) of the housing member 621. ) In the head 652 side direction (arrow A1 direction). At this time, the head main body 655 of the breaking screw 651 is in a state of being spaced from the latching portion 628 of the housing member 621 with an interval h1, so the shaft portion 653 side direction (downward in the drawing, ie, the direction of the arrow A2). Therefore, the head h 655 of the breaking screw 651 moves in the axial direction in the head main body receiving cavity 624 (first receiving portion) of the receiving member 621. It is a margin to get. On the other hand, at this upper limit position, there is still a gap h2 between the flange portion 657 in the separation portion 654 of the breaking screw 651 and the end surface (upper end surface) on the operation hole 622 side in the flange portion accommodating cavity 623. Therefore, if the separating portion 654 is in a state after being separated (ie, the head main body 655 of the breaking screw 651 is in the direction of the shaft portion 653 (in the direction of the arrow A2 in the head main body receiving cavity 624 of the receiving member 621). ) And the distance h1 between the head main body 655 and the latching portion 628 and the distance h2 between the flange portion 657 and the upper end surface of the flange portion accommodating cavity 623, and moves by the sum h1 + h2. Therefore, the sum h1 + h2 of the interval h1 and the interval h2 is such that the separating portion 654 of the breaking screw 651 is axial in the flange portion accommodating cavity 623 (second accommodating portion). And it has a margin that may be floating.

  Accordingly, at this time, the margin h1 in which the head body 655 of the breaking screw 651 can move in the axial direction within the head body housing cavity 624 (first housing section) of the housing member 621 is separated by the separation section 654 by the flange section housing cavity 623. Since the margin h2 is smaller than the margin h1 + h2 that can move in the axial direction in the (second accommodating portion), the breaking screw 651 and the accommodating member 621 before breaking are maximized in the axial direction. Even if it moves freely, the head main body 655 only comes into contact with both ends of the head main body accommodating cavity 624 (first accommodating portion) and is regulated, and the separating portion 654 is not connected to the flange portion accommodating cavity 623 (second accommodating portion). ) Does not hit the end of the), and play of at least the interval h2 is always secured. That is, even if the breaking screw 651 and the housing member 621 before breaking break each other in the axial direction due to an external force, this force is always transmitted between the head body 655 and the head body housing cavity 624. It is merely transmitted between the separation portion 654 and the flange portion accommodating cavity 623. Therefore, since no load is applied to the separation portion 654, it is difficult for the separation portion 654 to break erroneously.

  At this time, if the distance h2 between the flange portion 657 of the separation portion 654 and the upper end surface of the flange portion accommodation cavity 623 is 0 at the upper limit position, the separation portion 654 is separated from the flange portion accommodation cavity 623 ( The allowance that allows the head main body 655 of the breaking screw 651 to move in the axial direction within the second accommodating portion) is the allowance that allows the head main body 655 of the breaking member 651 to move axially within the head main body accommodating cavity 624 (first accommodating portion). It becomes equal to h1. At this time, as shown in FIG. 27, the tapered surface 655T of the head body 655 abuts against the lower end edge of the inner peripheral surface of the flange portion accommodating cavity 623, and at the same time, the flange portion 657 of the separating portion 654 is also in the flange portion accommodating cavity 623. Thus, the axial force is equally applied to both the head body 655 and the separation portion 654. Even in this case, it is difficult for the separating portion 654 to be erroneously broken because the load is not concentrated on the separating portion 654 alone. On the other hand, when the head main body 655 of the breaking screw 651 moves to the maximum in the shaft portion 653 side direction (arrow A2 direction) within the head main body housing cavity 624 (first housing portion) of the housing member 621, The head main body 655 hits the latching portion 628 of the housing member 621, but there is no structure on which the separation portion 654 hits during this process, so that no load is applied to the separation portion 654.

  From the above, the margin h1 in which the head body 655 of the breaking screw 651 can freely move in the axial direction within the head body housing cavity 624 (first housing section) of the housing member 621 is separated, and the separation section 654 is the flange section housing cavity. If it is equal to or smaller than the margin h1 + h2 that can move in the axial direction in 623 (second housing part) (ie h2 ≧ 0), for example, the breaking screw 651 and the housing member 621 are axially connected to each other by an external force. In the direction, the external force is evenly transmitted to the head body 655 and the separating portion 654, or the external force is transmitted only to the head body 655, that is, the external force is at least in the head body 655. As a result, only the separating portion 654 is not subjected to an external force, and therefore, the separating portion 654 is effectively prevented from being erroneously broken by the external force.

  Further, as shown in FIG. 27, in a state where the breaking screw 651 is housed in the radial center of the housing member 621 (that is, concentrically), the peripheral surface of the head body 655 and the housing of the breaking screw 651 are housed. There is a distance d1 between the member 621 and the inner peripheral surface of the head body housing cavity 624, and the head body 655 can move in the radial direction within the head body housing cavity 624 by 2 × d1. it can. That is, the margin that the head main body 655 of the breaking screw 651 can freely move in the radial direction within the head main body accommodating cavity 624 (first accommodating portion) of the accommodating member 621 is 2d1. On the other hand, in this concentric state, there is a gap d2 between the outer peripheral edge of the flange portion 657 in the separation portion 654 of the breaking screw 651 and the inner peripheral surface of the flange portion accommodation cavity 623 in the accommodation member 621. There is a gap d3 between the cylindrical portion 654P in the portion 654 and the inner peripheral surface of the operation hole 622 in the housing member 621. The former gap d2 is smaller than the latter gap d3 (d2 <d3). It has become. Therefore, if the separating portion 654 is in a state after being separated, the movement in the radial direction is restricted between the flange portion 657 and the flange portion accommodating cavity 623, and is twice the interval d2 (2 × d2) therebetween. Therefore, the movable range 2d2 is an allowance for allowing the separating portion 654 of the breaking screw 651 to move in the radial direction in the flange portion accommodating cavity 623 (second accommodating portion). Further, a distance d2 between the flange portion 657 and the flange portion accommodating cavity 623 is larger than a distance d1 between the head body 655 and the head body accommodating cavity 624. That is, the distance d1 between the head body 655 and the head body accommodation cavity 624, the distance d2 between the flange part 657 and the flange part accommodation cavity 623, and the distance d3 between the cylindrical portion 654P and the operation hole 622. Are in a relationship that increases in this order (d1 <d2 <d3), and therefore, the distance d1 between the head body 655 and the head body housing cavity 624 is minimum, so that Even if the breaking screw 651 and the housing member 621 are maximally free from each other in the radial direction, the head body 655 only abuts against the inner peripheral surface of the head body housing cavity 624 (first housing portion) and is restricted. In this case, the separating portion 654 does not hit the inner peripheral surface of the flange portion accommodating cavity 623 (second accommodating portion) nor the inner peripheral surface of the operation hole 622, and always plays between the inner peripheral surfaces. Is to be secured. That is, even if the breaking screw 651 and the housing member 621 before breaking break each other in the radial direction due to an external force, this force is always transmitted between the head body 655 and the head body housing cavity 624. It is merely transmitted between the separation portion 654 and the flange portion accommodating cavity 623 or the operation hole 622. Therefore, since no load is applied to the separation portion 654, it is difficult for the separation portion 654 to break erroneously.

  At this time, if the distance d1 between the head main body 655 and the head main body accommodating cavity 624 is equal to the distance d2 between the flange 657 and the flange accommodating cavity 623 (d1 = d2). That is, a margin 2d1 that allows the head body 655 of the breaking screw 651 to move radially in the head body housing cavity 624 (first housing section) of the housing member 621, and the separating section 654 in the flange section housing cavity 623 ( If it is equal to the margin 2d2 that can move in the radial direction in the second housing part), the head body 655 hits the inner peripheral surface of the head body housing cavity 624 and at the same time, the flange of the separation part 654 The portion 657 also hits the inner peripheral surface of the flange portion accommodating cavity 623, and the radial force is applied to both the head body 655 and the separation portion 654. Even in this case, it is difficult for the separating portion 654 to be erroneously broken because the load is not concentrated on the separating portion 654 alone.

  From the above, the margin 2d1 that allows the head main body 655 of the breaking screw 651 to freely move in the radial direction within the head main body accommodating cavity 624 (first accommodating section) of the accommodating member 621, and the separating section 654 as the flange accommodating cavity. If it is equal to or smaller than the margin 2d2 (2d1 ≦ 2d2) that can move in the radial direction in 623 (second accommodating portion), for example, the breaking screw 651 and the accommodating member 621 are mutually radial due to an external force. The external force is evenly transmitted to the head body 655 and the separating portion 654, or the external force is transmitted only to the head body 655, that is, the external force is received at least by the head body 655. As a result, only the separation portion 654 is not subjected to external force, and therefore, the separation portion 654 is effectively prevented from being erroneously broken by this external force.

  Further, in the housing member 621, the diameter of the head body housing cavity 624 (first housing section) is larger than the diameter of the flange section housing cavity 623 (second housing section). Since the diameter is increased stepwise from the flange portion accommodating cavity 623, the shape is more easily formed, and can be easily processed by header processing.

  In addition, the separating portion 654 of the breaking screw 651 in a state before breaking is held in a posture fitted to the operation hole 622 of the housing member 621. That is, as shown in FIG. 27, when the breaking screw 651 is at the upper limit position, the depth h3 in which the columnar portion 654P of the separation portion 654 is fitted in the operation hole 622 is the head body 655. Is larger (h3> h1) than the allowance h1 that can move in the axial direction in the head body housing cavity 624 (first housing portion), so that the breaking screw 651 is located at the upper limit position shown in FIG. Even if the shaft portion 653 moves in the direction toward the shaft portion 653 (downward, that is, in the direction of arrow A2) until it hits the latching portion 628, the peripheral surface of the cylindrical portion 654P in the separation portion 654 is still the inner peripheral surface of the operation hole 622. It is designed to be held in a posture fitted to the. In other words, even if the upper end of the cylindrical portion 654P in the separation portion 654 moves downward by the maximum movable range h1, there is still a residue in the fitting depth of the cylindrical portion 654P with respect to the operation hole 622 (h3- h1> 0). Therefore, since the screw hole of the breaking screw 651 is not drawn inward than the operation hole 622 of the housing member 621, the driver DR1 can be easily engaged with the screw hole from the outside, and the fastening operation is facilitated.

In addition, as shown in FIG. 26B, the housing member 621 holds the separation portion 654 after separation in the breaking screw 651 in a posture that does not protrude from the operation hole 622. That is, the depth h4 of the operation hole 622 in the housing member 621 shown in FIG. 27 is equal to or greater than the height (axial length) h2 + h3 of the cylindrical portion 654P in the separation portion 654 of the breaking screw 651 ( h4 ≧ h2 + h3).
In the present embodiment, the housing member 621 is surrounded by the peripheral wall of the second mounting base sealing portion 432, which is another structure, and as described above, it is difficult to grasp and rotate the housing member 621. However, if the separation portion 654 after separation protrudes from the operation hole 622, if the protruding portion is gripped with pliers or the like and rotated while being pulled strongly, the accommodating member 621 rotates and the breaking screw 651 loosens. possible. On the other hand, according to the configuration of the pachinko machine 10 of the present embodiment, since the separation portion 654 is held in a posture that does not protrude from the operation hole 622, it is difficult to grip the separation portion 654, and therefore it is accommodated from the outside. It is difficult to loosen the breaking screw 651 by rotating the entire member 621 in the reverse direction.

(Modification)
Various modifications can be made to the pachinko machine 10 of the above-described embodiment (hereinafter referred to as the first embodiment), for example, as listed below.

(1) (Second embodiment)
FIG. 28 is a front view showing another example of the breaking screw. The break screw 439 shown in the figure is composed of a head portion 491 and a shaft portion 492, similar to the break screw 651 in the first embodiment, and the head portion 491 has a screw hole (not shown) formed on the tip surface. The separated portion 613 and the head main body 614 are continuously formed so as to be aligned in the axial direction in this order from the distal end side, and the shaft portion 492 extends from the head main body 614. . The shapes of the separating portion 613 and the head main body 614 are the same as those of the breaking screw 651 in the first embodiment, and a constricted thin-diameter portion 615 is formed, and the columnar portion and the tapered shape of the separating portion 613 are formed. A flange portion 616 is formed between the portions.

  The breaking screw 439 shown in FIG. 28 is different from the breaking screw 651 in the first embodiment in that a head portion 614 is formed with a flange portion 617 extending radially in a position slightly closer to the separation portion 613 side. It is a point that has been. In addition, the shaft 492 forming side end surface of the head main body 614 may be provided with a knurling 618 made up of a plurality of radially extending notches for preventing loosening.

  As shown in FIG. 29, the same accommodating member 621 as in the first embodiment is fitted to the head 491 of the breaking screw 439 shown in FIG. For this reason, the same code | symbol is attached | subjected to the site | part similar to the above, and the description is abbreviate | omitted.

  According to the breaking screw 439 shown in FIG. 28, the flange portion 616 of the breaking screw 439 engages with the operation hole 622 of the housing member 621, and the head 491 of the breaking screw 439 cannot come out from the operation hole 622. On the other hand, the collar portion 617 is engaged with the latching portion 628 of the housing member 621 so that the head portion 491 of the breaking screw 439 cannot come out from the insertion hole 627, so the head portion 491 of the breaking screw 439 is It is securely held in the state of being accommodated in the accommodating member 621.

  Further, the insertion hole 627 of the latching portion 628 has a hole size through which the head main body 614 of the breaking screw 439 can be inserted. As shown in FIG. 29, the flange 617 is formed of the head main body of the breaking screw 439. A distance d10 larger than the thickness t10 of the latching portion 628 of the housing member 621 is formed from the end of the shaft portion 492 in 614. Thereby, the latching portion 628 has a slight margin (d10) between the surface of the second mounting base sealing portion 432 and the flange portion 617 with which the shaft portion 492 side end of the head body 614 of the breaking screw 439 abuts. -T10), and therefore, even when the breaking screw 439 is fastened, the housing member 621 can freely rotate with respect to the breaking screw 439, that is, in a state where it can freely idle (idle). Therefore, the reverse rotation of the breaking screw 439 from the outside can be reliably prevented. If there is no allowance as described above (that is, t10 = d10), when the accommodation member 621 is rotated, the breaking screw 439 is rotated together with the breaking screw 439 without idling, and as a result, it is accommodated from the outside. It is considered that it may be possible to loosen the breaking screw 439 by rotating the member 621.

  In the first embodiment, as described above, a slight gap is formed between the housing member 621 and the second mounting base sealing portion 432 when the housing member 621 is stored inside the second mounting base sealing portion 432. Therefore, for example, it is difficult to insert a finger or an instrument from the outside of the second mounting base sealing portion 432 and rotate the housing member 621. However, the housing member 621 is idled as described above. By adopting the configuration, it is possible to more reliably prevent the breaking screw 439 from being loosened. Further, for example, when the housing member is surrounded by a relatively large gap, or when the housing member is exposed without being surrounded by the peripheral wall of the sealing portion, the housing member is Therefore, it is particularly useful to make the housing member 621 idle as described above.

  Hereinafter, an example of the process of producing the fracture | rupture screw which has the above ridges with a header (forging machine) is demonstrated simply and sequentially.

1. First, a coil material (wire material) is cut into a predetermined length.

2. Next, as shown in FIG. 30 (a), the cut coil material S11 is set on the header and header processing is performed, and a part of the coil material S11 is bulged in the radial direction so that the head body S12 is In addition, as shown in FIG. 30 (b), a positive screw hole S15 is formed on one end surface of the coil material S11, while the head body S12 has the above-mentioned structure as shown in FIG. 30 (c). A knurl S17 is formed on an end face far from the screw hole S15.

3. Next, as shown in FIG. 30 (d), the header is further processed, and the end of the head main body S12 opposite to the knurl S17 formation side (that is, the end close to the screw hole S15) is further added. The flange S13 is formed by bulging in the radial direction.

4). Next, as shown in FIG. 30 (e), a round bar portion (that is, a round bar portion on the side opposite to the screw hole S15 formation side) extending from the end portion on the knurl S17 formation side in the head body S12 is cut. The screw thread is cut to form the shaft portion S14.

5. Next, as shown in FIG. 30 (f), a constricted small diameter portion S16 is formed in the round bar portion on the screw hole S15 formation side.

  The fracture screw can be easily produced by the method using the header processing as described above.

(2) (Third embodiment)
FIG. 31 is a perspective view showing another example of a housing member as a protective member, and FIG. 32 is a developed view thereof. The accommodating member 658 shown in the figure is prepared by forming a metal plate, which is a single plate-like member, into a generally rectangular shape (or a belt shape) extending slightly longer as shown in FIG. As shown in FIG. 31, the front and back surfaces of the rectangular parallelepiped are opened, and the top surface, bottom surface, and both side surfaces are substantially closed by the top plate 658T, the bottom plate 658B, and the side plates 658R, 658L, respectively. It is a holder obtained by assembling so as to have a substantially rectangular tube shape.

  An operation hole 659 having a diameter slightly larger than the diameter of the columnar portion 654P in the separation portion 654 of the breaking screw 651 and smaller than the outer diameter of the flange portion 657 is formed in the top plate 658T constituting the upper surface portion of the housing member 658. As shown in FIG. 31, the shaft 653 of the breaking screw 651 can be inserted into the bottom plate 658B constituting the lower surface portion, and the head body 655 of the head 652 cannot be inserted. A shaft insertion hole 660 having a hole size is formed. The shaft insertion hole 660 is provided with notches 660R and 660L that are recessed inward in a substantially U shape at the center of both end edges (both short edges) of the metal plate in the unfolded state shown in FIG. By bending both end edges (both short edges) together, each notch 660R, 660L is halved, and these are combined to form one hole. Further, as shown in FIG. 31, the bottom plate 658B is formed with a shaft introduction notch 661 that gradually expands from the shaft insertion hole 660 to the front side. The shaft introduction notches 661 have both front edges of the metal plate in the unfolded state shown in FIG. 32, and the front edge of the portion that becomes the bottom plate 658B is inclined obliquely inward, and both edges of the metal plate (both short edges). ) In which the front side portion is inclined inward from the shaft insertion hole 660 (that is, the obtuse corners are formed so that the right-angled corners on the front side at both ends of the metal plate are retracted obliquely inward. Part). The shaft introduction notch 661 functions to guide the shaft portion 653 from the front side to the shaft insertion hole 660 when the breaking screw 651 is housed in the housing member 658 as described later.

  Elastic plates 662R and 662L extending inward are provided on both side plates 658R and 658L constituting both side portions of the housing member 658, respectively. The elastic pieces 662R and 662L are provided with U-shaped cuts 663R and 663L at the portions to be the both side plates 658R and 658L of the metal plate in the unfolded state shown in FIG. 32, and inside the cuts 663R and 663L. It is formed by bending so as to cause the formed rectangular piece.

  At this time, both elastic pieces 662R and 662L of the housing member 658 abut against the tapered surface 655T of the head body 655 of the breaking screw 651 and urge the head body 655 of the breaking screw 651 so as to push down from above. Become.

  At this time, since the head 652 of the breaking screw 651 is rotatably held in the housing member 658 as described above, the breaking screw 651 can be turned with the driver DR1 while gripping the housing member 658 from the outside. Easy screwing operation. That is, as in the case of the first embodiment, the housing member 658 can also function as a support (support) for the breaking screw 651 during the screwing operation.

  As in the case of the first embodiment, after the breaking screw 651 is screwed in until it is fastened (finally tightened) and then rotated at a higher torque, the head 652 of the breaking screw 651 becomes the small diameter portion 656. The separation part 654 is separated from the head body 655.

  At this time, similarly to the case of the first embodiment, in the state where the housing member 658 is housed inside the second mounting base sealing portion 432, it is between the second mounting base sealing portion 432. Since there is only a slight gap, for example, it is difficult to rotate the housing member 658 by inserting fingers or instruments from the outside of the second mounting base sealing portion 432.

  In addition, since the housing member 658 is formed by processing a single metal plate, the operation hole 659, the side plates 658R and 658L, and the lower surface portion can be easily formed by punching or bending the metal plate. A bottom plate 658B and the like can be formed. Further, the elastic pieces 662R and 662L can be easily formed by inserting the notches 663R and 663L into the side plates 658R and 658L and bending them.

(3) (Fourth embodiment)
FIG. 33 is a development view showing another example of the housing member. The housing member 671 shown in the figure is configured by bending a single metal plate prepared in a substantially rectangular shape that extends slightly longer, similar to the housing member 658 in the third embodiment. In the case of the embodiment, the top plate 671T, the side plate 671R, and the bottom plate 671B are formed in this order from one end side of the metal plate, and the metal plate is bent in a U shape around the side plate 671R. ing. The top plate 671T and the side plate 671R are provided with operation holes 672 and elastic pieces 673R similar to those of the housing member 658 in the third embodiment. Unlike the bottom plate 658B of the housing member 658 in the third embodiment, the bottom plate 671B is configured as an integrated plate body without being divided, and the shaft portion 653 of the breaking screw 651 is inserted through the central portion. A shaft insertion hole 674 having a hole diameter that cannot be inserted through the head body 655 of the head 652 is formed.

  In the case of the accommodating member 671 in the fourth embodiment, since not only the front and back surfaces but also one side surface is open, there is also an advantage that the operation of inserting and accommodating the head 652 of the breaking screw 651 is easy. However, on the other hand, it is easy to open the portion having the operation hole 672 (top plate 671T) so as to return it in the direction opposite to the bending direction and open the upper surface portion. There is a tendency that fraud is easily done.

(4) (Fifth embodiment)
FIG. 34 is a development view showing still another example of the housing member. The housing member 675 shown in the figure extends from the top plate 675T corresponding to the top plate 658T of the housing member 658 in the third embodiment to the both sides in the width direction, and a front plate 675F and a back plate 675W are formed respectively. The housing member 658 in the third embodiment has the same configuration as the third embodiment except that the housing member 658 in the third embodiment has a substantially rectangular shape that extends slightly in the expanded state. In the housing member 675 according to the fifth embodiment, the front plate 675F and the back plate 675W are added to the housing member 675, so that the housing member 675 has a generally cross shape in the developed state.

In the case of the housing member 675 in the fifth embodiment, the upper surface, the lower surface, the both side surfaces, the front surface, and the rear surface are all closed, so that the separation portion 654 after the breaking screw 651 is separated is more securely held. The drop-off prevention effect is further improved, and all of the separation part 654 except for the screw hole forming surface in the state before the breakage is completely covered from the six surfaces, so that the protective effect is further improved.
Further, the head main body 655 is also covered on all six surfaces, so that it is more difficult for an unauthorized operation from the outside to reach.
Furthermore, since the breaking screw 651 is unlikely to be detached from the housing member 675 and erroneous breakage is unlikely to occur, the housing member 675 attached to the breaking screw 651 can be flowed in large quantities to the gaming machine manufacturing line.

  In particular, the four plates of the side plates 675L and 675R, the front plate 675F, and the back plate 675W are formed so as to extend in four directions from the top plate 675T, and therefore the peripheral edge of the upper surface portion of the housing member 675 is formed. Since it is not a joint but a crease, it is more difficult to perform an illegal act of entering an unauthorized tool from above the housing member 675. At this time, for example, the periphery of the upper surface portion may be used as a seam, and the seam may be joined by welding. However, since the number of man-hours is increased, the periphery of the upper surface portion that is prone to fraud is folded as described above. By using the eyes, it is possible to efficiently prevent fraud without performing welding or the like.

  Further, the accommodating member 675 in the fifth embodiment is formed with both elastic pieces 685R and 685L similar to the elastic pieces 662R and 662L of the accommodating member 658 in the third embodiment. Since all the six surfaces of the accommodation member 675 in the form are closed as described above, a required function as a holder for holding the separation portion 654 after separation is ensured by this closed structure, and therefore the drop prevention effect From this point of view, it is possible to further simplify the configuration by omitting the formation of the two elastic pieces 685R and 685L.

(5) (Sixth embodiment)
FIG. 35 is a bottom view showing still another example of the housing member. The housing member 682 shown in the figure has the same configuration as the housing member 658 in the third embodiment except for the configuration of the bottom plate 682B. The bottom plate 682B in the sixth embodiment is divided and configured in the same manner as the bottom plate 658B of the housing member 658 in the third embodiment, but the divided bodies are formed to be slightly longer and overlap each other. . As a result, the shaft insertion hole 683 is securely held in a closed state unless each of the divided parts of the bottom plate 682B is expanded to both sides larger than in the case of the third embodiment. The shaft portion 653 is configured to be more difficult to detach.

  Further, in the sixth embodiment, the shaft introduction notch 684 having a shape recessed in a V shape from the front side is configured such that the oblique sides 682D and 682D facing each other in each divided body of the bottom plate 682B intersect. However, when the accommodating member 682 is attached to the breaking screw 651, if the shaft portion 653 of the breaking screw 651 is pushed into the inner back portion of the shaft introduction notch 684, each division of the bottom plate 682B is performed accordingly. Both oblique sides 682D and 682D in the body gradually expand to both sides, and the shaft portion 653 of the breaking screw 651 is guided further inward, and the shaft portion 653 of the breaking screw 651 reaches the shaft insertion hole 683 and the inside thereof. Then, both oblique sides 682D and 682D return to their original positions due to elasticity, and the shaft insertion hole 683 is also closed, and the shaft portion 653 of the breaking screw 651 is inserted into the shaft insertion hole 683. And it is surely held. In this manner, the breaking screw 651 can be accommodated only by pushing the shaft portion 653 of the breaking screw 651 inwardly from the shaft introduction notch 684 without having to divide the divided parts of the bottom plate 682B on both sides. 682 can be easily attached.

(6) (Seventh embodiment)
FIG. 36 is a perspective view showing still another example of the housing member. The housing member 664 shown in the figure is a resin holder having a shape in which both end faces of the cylindrical body are substantially closed.

  An operation hole 665 having a hole diameter substantially equal to that of the operation hole 659 of the housing member 658 in the third embodiment is formed in the central portion of the one end surface of the housing member 664, and a breaking screw 651 is formed in the central portion of the other end surface. A shaft insertion hole 666 having a hole diameter through which the shaft portion 653 can be inserted and the head main body 655 of the head 652 cannot be inserted is formed. An opening 667 having a rectangular shape when viewed from the front is formed in the peripheral wall portion of the housing member 664 at the end where the shaft insertion hole 666 is formed. A slit 668 extending in the radial direction is formed on the end surface so as to communicate with the central portion in the circumferential direction of the opening 667 and the shaft insertion hole 666 at both ends. Elastic pieces 669R and 669L extending inward are provided at two opposing positions on the peripheral wall portion of the housing member 664, respectively.

  The head member 652 of the breaking screw 651 is inserted into the housing member 664 from the opening 667 and housed. At this time, the shaft portion 653 of the breaking screw 651 is inserted into the shaft insertion hole 666 through the slit 668. To do. The width of the slit 668 is slightly smaller than the diameter of the shaft portion 653 of the breaking screw 651. However, since the housing member 664 is a resin molded product having appropriate flexibility, the width of the slit 668 is slightly reduced. While the shaft portion 653 of the breaking screw 651 can be pushed in while being expanded, the breaking screw 651 passes through the slit 668 after the shaft portion 653 of the breaking screw 651 is inserted into the shaft insertion hole 666. It is difficult to detach from the housing member 664 and is securely held in the shaft insertion hole 666. As described above, the housing member 664 is fitted to the head 652 of the breaking screw 651.

The housing member 664 of the seventh embodiment shown in FIG. 36 can basically function substantially the same as the housing member 658 of the third embodiment, including the elastic pieces 669R and 669L. Since the side surface portion of the housing member 664 is configured in a peripheral wall shape surrounding the periphery of the head portion 652 of the breaking screw 651, the separated portion 654 after being separated is surrounded by the peripheral wall side surface portion. Therefore, it is held more securely and the drop-off preventing effect is further improved, and the separation portion 654 in the state before breaking is also covered from the surroundings, so that the protective effect is further increased. It is good.
Further, the head main body 665 has a configuration in which it is more difficult for an unauthorized operation from the outside to be performed by being surrounded by a peripheral wall-shaped side surface.

  Moreover, since it is comprised in the shape of the surrounding wall surrounding the circumference | surroundings of the head 652 of the fracture | rupture screw 651, since it becomes the structure closed as a whole except the opening part 667 grade | etc., In the said 5th embodiment. As in the case of the housing member 675, it is possible to omit the formation of the elastic pieces 669R and 669L and to simplify the configuration only from the viewpoint of the drop-off preventing effect, but from the viewpoint of preventing fraud. It is desirable to form both elastic pieces 669R and 669L.

  Further, since the housing member 664 is made of resin, the housing member 664 can be easily and inexpensively manufactured. In particular, the elastic pieces 669R and 669L can be easily formed by integral molding. Further, since the housing member 664 has an appropriate deformability, it is possible to house the breaking screw 651 while appropriately deforming the housing member 664, and therefore, the work of housing the breaking screw 651 is facilitated. . Furthermore, since this moderate deformability has a buffering effect to absorb external impacts, the function as a protective member is also good.

(7) (Eighth embodiment)
37 and 38 are perspective views showing still other examples of the housing member. The housing member 687 shown in the figure is a resin holder having a substantially cylindrical outer shape, like the housing members 621 and 664 in the first embodiment and the seventh embodiment.

  The housing member 687 is not formed so as to hold the entire cylindrical outer shape invariably (except in the case of elastic deformation or tearing) as shown in FIGS. 39 and 40. In addition, the two divided parts 688 and 689 are connected to be openable and closable, and the divided parts 688 and 689 are closed to form a cylindrical outer shape shown in FIGS. 37 and 38. That is, as shown in FIG. 39 and FIG. 40, most of the general cylindrical body excluding the upper end is cut (vertically divided) by one plane including the shaft and divided into two, and a disk-shaped top plate is formed at the upper end. A first divided portion 688 in which a portion 688T is formed and the lower part of the portion 688T has a substantially semi-cylindrical shape; and a substantially semi-cylindrical shape symmetrical to the substantially semi-cylindrical portion of the first divided portion 688. Each of the first divided portion 688 and the second divided portion 689 facing each other at one side edge (the boundary between the cut surface and the peripheral surface, The end edge extending in parallel with the axial direction) is integrally formed so as to be continuous through the flexible portion 690. The flexible portion 690 extends long along the axial direction of the housing member 687 and is formed so that the central portion in the width direction is slightly thin, and is folded in half at the central portion to form a substantially triangular cross section. The first divided portion has a configuration that can be freely deformed between a closed body posture (see FIG. 38) and an open body force (see FIG. 39) that is expanded so as to push and expand in the width direction from the closed body force. 688 and the second divided portion 689 are integrally formed.

  As described above, the housing member 687 is not configured to be divided only at the upper end portion, and is integrally formed with the first divided portion 688 as a top plate portion 688T. That is, the top plate portion 688T constituting the upper end portion of the first divided portion 688 extends toward the second divided portion 689 so as to form a circular shape in plan view as a whole, while the second divided portion 689 is formed from the top plate. The upper end is shorter than the first divided portion 739 by the thickness of the top plate portion 688T so that the upper end is in contact with the lower end of the portion 688T. In other words, the housing member 687 is integrally formed with the first divided portion 688 as the top plate portion 688T at the upper end portion, and the first divided portion 688 and the second divided portion are below the top plate portion 688T. It has a shape that is vertically divided into two parts 689 and divided into two.

  In the accommodating member 687, as shown in FIGS. 37 and 38, a boundary line B1 between the first divided portion 688 and the second divided portion 689 extends upward along one side surface from the lower end of the accommodating member 687, At a position slightly below the upper end, that is, at the position of the lower end of the top plate portion 688T, it is bent at a right angle toward the second divided portion 689 side and extends horizontally to a position moved by 180 ° to the other side surface along the circumferential direction. It is bent downward at a right angle again and extends to the lower end along the other side surface. That is, the boundary line B1 between the first divided portion 688 and the second divided portion 689 extends so as to avoid the upper end surface of the accommodating member 687, that is, the end surface where the operation hole 701 is formed, and appears on the end surface where the operation hole 701 is formed. There is no such thing.

  As shown in FIGS. 39 and 40, the free end edge portion of the first divided portion 688 (that is, the end portion opposite to the side where the flexible portion 690 is formed) is cut out in a U-shape when viewed from the front. A recess 691 is formed, and an engagement protrusion 692 is formed at the center of the inner back side surface of the recess 691 so as to straddle the surface (cut surface) facing the second divided portion 689. The engagement protrusion 692 is a first rectangular portion of one of four corners including four ridge lines parallel to the axial direction of the housing member 687 in a substantially rectangular parallelepiped having a rectangular column shape that is slightly longer in the axial direction of the housing member 687. The first divided portion is formed so as to have a shape in which a curved surface 692C is formed by cutting a corner that is opposite to the corner and rounding off a corner so as to bite into the free edge of 688. 688 is integrally formed. The projecting height of the engaging protrusion 692 is substantially equal to the depth of the recessed portion 691, and therefore is fitted in the recessed portion 691 without projecting from the outer periphery of the first divided portion 688. Engagement protrusions 693 are formed on the free end edge of the second divided portion 689 so as to project in an annular shape in a U shape toward the first divided portion 688. The outer shape of the engaging protrusion 693 is accommodated in the recessed portion 691, and the engaging protrusion 692 enters and exits from a rectangular opening 693 </ b> A formed inside the engaging protrusion 693. It has come to be able to do. When the first divided portion 688 and the second divided portion 689 are brought into contact with each other such that the cut surfaces overlap each other, the engagement protrusion 693 is elastically engaged with the engagement protrusion 692 as shown in FIGS. As a result, the first divided portion 688 and the second divided portion 689 are fixed in a closed state so that the housing member 687 has a substantially cylindrical outer shape.

  At this time, the engagement protrusion 692 is easily guided into the opening 693A of the engagement protrusion 693 by the curved surface 692C. In addition, when the engaging protrusion 693 is engaged with the engaging protrusion 692, the engaging protrusion 693 is accommodated in the recessed portion 691 and substantially fills the space in the recessed portion 691, and as shown in FIG. In addition, a part of the outer peripheral surface of the housing member 687 is configured. On the other hand, when the first divided portion 688 and the second divided portion 689 are brought together, as shown in FIG. 38, the flexible portion 690 is folded in half so as to form a substantially triangular cross section. By being deformed, it functions like a hinge, so that the first divided portion 688 and the second divided portion 689 can be opened and closed so as to rotate about the flexible portion 690 forming side edge. ing.

  As shown in FIGS. 39 and 40, the first divided portion 688 has inner surface shapes corresponding to the outer surface shapes of the separating portion 654 and the head body 655 in the breaking screw 651 of the first embodiment. And a separation portion accommodation recess 694 and a head body accommodation recess 695 that cover one half of each of the separation portion 654 and the head body 655 from the side. In the second divided portion 689, a separating portion receiving recess 696 and a head body receiving recess 697 that are configured symmetrically with the separating portion receiving recess 694 and the head body receiving recess 695 of the first divided portion 688 are formed. The other half of each of the separating portion 654 and the head body 655 in the breaking screw 651 is covered from the side.

  As shown in FIGS. 37 to 39, the top plate portion 688T of the first divided portion 688 is slightly larger than the diameter of the columnar portion 654P in the separation portion 654 of the breaking screw 651 and the outer diameter of the flange portion 657. A circular operation hole 701 having a smaller diameter is formed. The operation hole 701 can be screwed in by exposing a screw hole 651H (see FIG. 42) provided in the distal end surface of the separating portion 654 of the breaking screw 651 to the outside, like the operation hole in each of the above embodiments. In addition, it functions to hold the separated portion 654 inside the housing member 687, and the inner peripheral surface of the operation hole 701 maintains the same diameter from the inner edge and extends slightly outward. After that, it is formed in a reverse taper shape that gradually expands toward the outside, and is accommodated in the separation portion accommodating recesses 694 and 696 when the accommodating member 687 is attached to the breaking screw 651. A driver can be easily engaged with the screw hole 651H of the separation portion 654. Further, due to the shape of the tip, the breaking screw 651 is accommodated at a position where the tip of the head 652 is retracted inward from the tip of the accommodating member 687.

  As shown in FIGS. 38 to 40, a head insertion groove 701G having a rectangular cross section extending from the operation hole 701 toward the second divided portion 689 is formed on the inner side surface of the top plate portion 688T. The head insertion groove 701G is a groove for inserting the distal end portion (columnar shape portion 654P) of the separation portion 654 of the breaking screw 651, and has a width equal to the diameter of the operation hole 701, and the inner end thereof is the operation portion. While communicating with the hole 701, the outer end penetrates to the side of the top plate portion 688T (to the second divided portion 689 side).

  As shown in FIGS. 39 and 40, the opposing ends of the walls constituting the bottom wall, that is, the end surface opposite to the top plate portion 688T formation side, in each of the first divided portion 688 and the second divided portion 689. In the center of the edge, semicircular cutout portions 702 and 703 having a diameter slightly larger than the outer diameter of the shaft portion 653 of the breaking screw 651 and smaller than the outer diameter of the head body 655 are formed. When the first divided portion 688 and the second divided portion 689 are brought together, the notches 702 and 703 are united to form a circular insertion hole (not shown).

  As shown in FIGS. 37 and 40, an elastic engagement piece 705 is formed at the central portion of the peripheral wall of the first divided portion 688. The elastic engagement piece 705 forms a flat portion 705S having a rectangular opening inside by cutting out a central portion of the peripheral surface of the first divided portion 688 into a flat shape, and an upper end edge (top plate portion) of the opening. 688T forming side edge) to the vicinity of the lower end edge, and is formed integrally with the first divided portion 688 so as to extend so as to hang down in a substantially quadrangular prism shape, and on the peripheral wall of the first divided portion 688 With the continuous upper end portion as a fixed end portion, the extended end side which is the free end side can be elastically deformed so as to bend inward and outward (in the radial direction of the first divided portion 688) as indicated by an arrow A3 in FIG. It has become. As shown in FIG. 37, the free end portion (extending end portion) of the elastic engagement piece 705 has a side-view shape and extends perpendicularly outward along the radial direction of the first divided portion 688, Thereby, the first engagement protrusion 705D is formed. The upper end side surface (the surface facing the fixed end side of the elastic engagement piece 705) of the first engagement protrusion 705D is formed in a planar shape perpendicular to the length direction (extension direction) of the elastic engagement piece 705, and the lower end The side surface (the surface facing the free end side of the elastic engagement piece 705) is formed in a slope shape inclined upward from the inside to the outside, and therefore the first engagement protrusion 705D has a lower end edge from the inside. The projection has a trapezoidal side shape that forms a hypotenuse inclined upward toward the outside, and the remaining three sides form a horizontal piece and a vertical side. Further, a second engagement protrusion that protrudes in the same direction as the first engagement protrusion 705D at a position slightly above the first engagement protrusion 705D (position close to the fixed end) of the elastic engagement piece 705. 705P is formed. The second engagement protrusion 705P is a protrusion having a side shape that tapers into a trapezoidal shape in which both upper and lower end edges are inclined downward and upward from the inside to the outside, and both inner and outer edge edges form a vertical side. It has become. The protruding height of the first engaging protrusion 705D (the protruding height from the flat surface 705S) is slightly larger than the protruding height of the second engaging protrusion 705P.

  With the first divided portion 688 and the second divided portion 689 opened, the breaking screw 651 is fitted into the first divided portion 688 as shown in FIG. 41, and the first divided portion 688 and the second divided portion 688 are connected as described above. The housing member 687 can be attached to the breaking screw 651 by closing the two-divided portion 689 and engaging and fixing the engaging protrusions 693 and the engaging protrusions 692. When the breaking screw 651 is fitted into the first divided portion 688, the tip end portion (columnar portion 654P) of the breaking portion 654 of the breaking screw 651 is inserted inward along the inner surface of the head insertion groove 701G. To do. When the breaking screw 651 is fitted into the first divided portion 688, the distal end surface of the separating portion 654 (cylindrical portion 654P) is positioned so as to align with the operation hole 701, and is formed on the distal end surface as shown in FIG. The screw hole 651H thus formed is exposed from the operation hole 701 to the outside. In this mounted state, the housing member 687 is in a state in which the head 652 of the breaking screw 651 is housed therein (strictly, in addition to the head 652, the base portion of the shaft portion 653 is covered by the insertion hole). ing.

  The breaking screw 651 fitted with the housing member 687 as described above can be used for a connecting portion of any member as long as it can be screw-fixed. It is also possible to use it for a part where the screw 651 is exposed, and in this way, in addition to the function as a protective member, the housing member 687 serves as a holder for holding the separation part 654 after separation. However, from the viewpoint of preventing fraud, the breaking screw 651 is surrounded by a structure such as a peripheral wall like the second mounting base sealing portion 432 in the first embodiment. According to this, for example, the breaking screw 651 is rotated loosely together with the housing member 687, or the housing member 687 is removed from the breaking screw 651. It may be more difficult for such loosened by turning forcibly reversed by some means the head body 655. Furthermore, as illustrated below, it is more desirable to configure the connecting portion so as to be particularly adapted to the housing member 687 of the eighth embodiment.

A base frame wall 736B is formed between both side portions of the wall 736 in parallel with the front end surface 707P of the second component member 707. Further, between the base frame wall 736B and the front end portion of the inner frame wall 736, the base frame wall 736B is formed. Three erection beams 737 are formed at a predetermined interval in the length direction of the base frame wall 736B. The first seal is formed by the inner frame wall 736, the base frame wall 736B, and the erection beam 737. Four sections respectively corresponding to the positions of the four screwing portions 710 in the stop portion 708 are formed. The inner frame wall 736 is fitted to the outer frame wall 721 of the first sealing portion 708 from the inside when the first component member 706 and the second component member 707 are slid and fitted as will be described later. As a result, the front end surface 707P of the second component member 707 is held at a predetermined distance from the outer frame wall 721 of the first sealing portion 708 (in other words, the first component member 706 and the first component 706 The two component members 707 are held in a position aligned with each other), and supports the screwed portion 710 and the broken screw loading portion 724 together with the outer frame wall 721 of the first sealing portion 708 while protecting them from the surroundings. It is intended to function. The erection beam 737 is disposed at a substantially central height position of the breaking screw loading portion 724, is formed in a strip shape extending in a slender shape from the base frame wall 736B to the front end side (front side), and is flattened. The leading end is continuous with the lower end edge of the inner frame wall 736.

  The breaking screw loading portion 724 is a cylindrical body having a depth substantially equal to the entire length of the breaking screw 651 and an inner diameter substantially equal to the outer diameter of the accommodating member 687 and extending vertically, and the lower end surface thereof is substantially defined by the lower wall 728.

A fitting groove 735 is formed. The flexible part fitting groove 735 is a groove having a substantially arc-shaped cross section in which the flexible part 690 of the housing member 687 can be fitted.

  One broken screw loading portion 724 is formed in each of the four sections of the inner frame portion 727 so as to correspond to the four screwed portions 710 in the first sealing portion 708. In other words, four breaking screw loading portions 724 are provided so as to be juxtaposed along the tip edge of the second component member 707. The broken screw loading portion 724 shown in FIG. 42 and FIG. 46 is one of these four, which is one disposed at a position closest to one end, that is, a corner on the distal end edge of the second component member 707, The remaining three adjacent to this are arranged so as to be aligned in a straight line toward the other end on the leading edge of the second component member 707. As in the case of the threaded portion 710 in the first sealing portion 708 described above, these four broken screw loading portions 724 all have the same configuration, so in the figure, the remaining three broken screw loading portions are shown. Although 724 is omitted in the drawing, only a part of one bracket 729 in another breaking screw loading portion 724 adjacent to the breaking screw loading portion 724 shown in FIG. As described above, the four sealing screw loading portions 724 formed so that the second sealing portion 707 is juxtaposed in a line along the distal end surface 707P of the second component member 707 are arranged in the inner frame portion 727. The frame wall 736, the base frame wall 736 </ b> B, and the erection beam 737 are configured to be supported while being surrounded one by one.

  Further, in the vicinity of the tip edge on the closing side surface (surface opposite to the peripheral wall forming side) of the second component member 707, relief-like projections 707N are formed at positions corresponding to the respective fracture screw loading portions 724. The relief-shaped projections 707N have a shape representing four numbers assigned to a total of four sets including a set of a threaded portion 710 of the first sealing portion 708 and a broken screw loading portion 724 of the second sealing portion 709. It has been molded. 42 and 46 show a relief-shaped projection 707N formed in a shape representing the number “1” corresponding to the one broken screw loading portion 724 shown in the drawing, and is shown adjacent to this. Although not shown, embossed protrusions 707N formed in a shape representing numbers “2”, “3”, and “4” corresponding to the remaining three broken screw loading portions 724 are formed in one row.

  A total of four sets including a set of the threaded portion 710 of the first sealing portion 708 and the breaking screw loading portion 724 of the second sealing portion 709 are used to be connected and sealed one at a time. For example, the connection sealing and the releasing operation can be repeated up to four times. At that time, each time the connection sealing is performed, a break screw 651 fitted with the accommodating member 687 may be prepared. In this embodiment, the temporary holding mechanism is configured as described above. Therefore, the breaking screw 651 fitted with the housing member 687 can be temporarily held in the second sealing portion 709 in advance, thereby making it possible to perform the connecting and sealing work more easily. That is, for example, in the manufacturing stage of a gaming machine, if the breaking screws 651 fitted with the housing members 687 are temporarily held in the four second sealing portions 709, they are connected for the purpose of inspection after that. Even when the sealing is released and the connection sealing is performed again, there is no need to newly prepare the breaking screw 651 with the accommodating member 687 attached, or the breaking screw 651 with the accommodating member 687 is accommodated as a spare. There is no need to provide a separate space or mechanism in the gaming machine.

  Specifically, when connecting the first component member 706 and the second component member 707 at the manufacturing stage of the gaming machine, as shown by an arrow A4 in FIG. 43, the broken screw loading portion of the second sealing portion 709 A breaking screw 651 fitted with a housing member 687 is inserted into 724 from the shaft portion 653 side. At this time, the elastic engagement piece 705 and the flexible portion 690 of the housing member 687 are fitted into the engagement groove 733 and the flexible portion fitting groove 735 of the breaking screw loading portion 724, respectively, While making it slide along the bending part fitting groove 735, the breaking screw 651 equipped with the accommodation member 687 is inserted. Since the protrusion height of the first engagement protrusion 705D in the elastic engagement piece 705 of the storage member 687 is slightly larger than the depth of the engagement groove 733 as described above, the breaking screw 651 fitted with the storage member 687 is attached. When inserting, the lower slope of the first engagement protrusion 705D is brought into contact with the upper end of the inner inner surface of the engagement groove 733 as the accommodating member 687 is pushed into the breaking screw loading portion 724. By sliding in contact with each other, the elastic engagement piece 705 is pressed and inserted into the engagement groove 733 while being elastically deformed so as to be drawn inward. As shown in FIG. 47, when almost the entire accommodation member 687 is inserted into the breaking screw loading portion 724, the first engagement protrusion 705D of the elastic engagement piece 705 engages with the engagement groove 733. It reaches the stepped portion 734, is guided by the downwardly inclined upper surface of the engaging stepped portion 734, and gets over while being further elastically deformed inward. The engaging stepped portion 705D and the second engaging protruding portion 705P The posture is engaged with the portion 734 interposed therebetween. Thereby, the breaking screw 651 fitted with the housing member 687 is temporarily held at a height position where the upper end thereof is aligned with the upper end of the breaking screw loading portion 724. Similarly, the remaining three broken screw loading portions 724 are inserted and temporarily held by the broken screws 651 fitted with the housing members 687.

  At this time, the horizontal surfaces of the upper end surface of the first engagement protrusion 705D in the elastic engagement piece 705 of the housing member 687 and the lower end surface of the engagement step portion 734 in the engagement groove 733 of the breaking screw loading portion 724 are engaged with each other. Thus, the housing member 687 is securely held so as not to be detached from the temporary holding position.

  At this time, since the breaking screw 651 is accommodated so as to retreat inward with respect to the accommodating member 687 as described above, the length from the upper end of the accommodating member 687 to the distal end of the shaft portion 653 of the breaking screw 651 is likely. Therefore, in the temporary holding state, as shown in FIG. 47, the tip end portion of the shaft portion 653 of the breaking screw 651 passes through the shaft insertion hole 730 in the breaking screw loading portion 724. It penetrates and slightly projects below the lower wall 728. Further, as described above, the protrusion 731 is formed on the lower surface of the lower surface wall 728 of the breaking screw loading portion 724, and the protrusion 731 has a slightly higher protruding height than the protruding portion of the shaft portion 653 of the breaking screw 651. It is formed to be large. Accordingly, when the first component member 706 and the second component member 707 are slid and fitted to each other as will be described later, they are inserted into the guide groove 718 of the screwed portion 710 in the first sealing portion 708. The protrusion 731 is inserted and moved along the guide groove 718, and accordingly, the tip of the shaft portion 653 of the breaking screw 651 is held in a floating posture without coming into contact with the bottom of the guide groove 718. However, the first sealing portion 708 is accurately guided to just above the screw hole 717 of the screwing portion 710. Further, when the protruding portion of the shaft portion 653 in the breaking screw 651 is pushed up due to a strong impact for some reason during handling, for example, the first engaging protrusion 705D of the elastic engaging piece 705 or the breaking screw loading portion in the housing member 687 Although the engagement step portion 734 of 724 may be damaged and the temporary holding state may be erroneously released, the protrusion 731 protects the shaft portion 653 of the breaking screw 651 from such a strong impact. Also works.

  As shown by arrows A5 and A6 in FIG. 43, the first constituent member 706 and the second constituent member 707 are arranged such that the first sealing member 708 forming side end of the first constituent member 706 is the second constituent member 707's second end. 2 The first component member 706 and the second component member are aligned with each other with a posture shifted from each other so as to protrude toward the tip side from the end on the side where the sealing portion 709 is formed, and then to the position where both ends are aligned. One or both of 707 are fitted so as to slide toward each other. At this time, a plurality of hook-shaped engagement pieces 706E project from the both side edges of the first component member 706 toward the second component member 707 at intervals, and on the other hand, both sides of the second component member 707 An engagement groove (not shown) having a hook-shaped internal shape corresponding to the engagement piece 706E is formed at the end edge, and the engagement piece 706E is fitted and engaged in the engagement groove. Thus, the first component member 706 and the second component member 707 are fixed in a fitted state. At this time, the breaking screw loading portion 724 of the second sealing portion 709 is on the upper peripheral wall 713F of the first sealing portion 708, and the inner frame wall 736 of the second sealing portion 709 is the outer frame of the first sealing portion 708. Each of the first and second components 706 and 707 is aligned with each other so that the end portions of the first component member 706 and the second component member 707 are aligned with each other, and further sliding movement is restricted. .

  At this time, the tip of the shaft portion 653 and the protrusion 731 of the breaking screw 651 protrude from the lower surface of the lower surface wall 728 of the breaking screw loading portion 724, but the screwing portion 710 of the first sealing portion 708. As described above, the guide groove 718 is formed on the bearing surface wall 712 of the first member 706, and the notch 719 is formed on the upper edge of the wall constituting the front end surface 706P of the first component member 706. Since the tip of the portion 653, the protrusion 731 and the protrusion 732 are fitted in the guide groove 718 and the notch 719 and slide along the guide groove 718, the bottom wall of the fracture screw loading portion 724 The lower surface of 728 and the upper surface of the bearing surface wall 712 at the threaded portion 710 have an uneven shape that follows each other, and a gap is substantially formed between them. So that the can fitted in a state that is almost close contact without.

  In the state where the first component member 706 and the second component member 707 are fitted as described above, the screwing portion 710 of the first sealing portion 708 and the breaking screw loading portion 724 of the second sealing portion 709 are arranged. As shown in FIG. 48, in any one of the four sets of sets, as shown in FIG. 48, the breaking screw 651 temporarily held together with the housing member 687 in the breaking screw loading portion 724 is screwed with a screwdriver, fastened, and separated. The part 654 is separated, and thereby the first component member 706 and the second component member 707 are connected and sealed.

  When this connection sealing is performed, the breaking screw 651 has a posture (hereinafter referred to as “the position where the tip of the shaft portion 653 is positioned on the same shaft near the outside of the screw hole 717 in the screwed portion 710 of the first sealing portion 708”). If it is screwed with the screwdriver as it is, the inside of the breaking screw loading portion 724 will be moved inwardly in the axial direction together with the housing member 687. That is, the breaking screw 651 is guided while being accurately held on the axis of the screw hole 717 by the housing member 687 and the breaking screw loading portion 724. Accordingly, it is not necessary to hold the breaking screw 651 directly by hand, and the screw can be screwed in a state in which the breaking screw 651 is held in a posture capable of being screwed more accurately and surely. It can be carried out. At this time, the second engagement protrusion 705P of the elastic engagement piece 705 of the housing member 687 is a slope whose lower end surface is inclined upward as described above, and the engagement step portion 734 of the engagement groove 733 is also an upper surface. Therefore, the second engaging projection 705P can easily get over the engaging step 734 of the engaging groove 733, so that the housing member 687 is moved inward from the temporary holding position. You can enter easily.

  This connection sealing can be similarly performed in any of a total of four sets including a combination of the screwing portion 710 of the first sealing portion 708 and the breaking screw loading portion 724 of the second sealing portion 709. The order of use is also arbitrary, but if the connection and sealing are performed one by one in the order of the numbers indicated by the relief-shaped projections 707N, the operation becomes clearer and easier to perform.

  In addition, even if, for example, any of the breaking screws 651 temporarily held in the breaking screw loading portion 724 is accidentally pushed inward from the temporary holding position before the connection sealing, the accommodating member Since the second engagement protrusion 705P of the elastic engagement piece 705 of 687 is an inclined surface whose upper end surface is inclined downward as described above, it penetrates the shaft insertion hole 730 in the breaking screw loading portion 724 and is below the lower surface wall 728. When the tip of the shaft portion 653 of the breaking screw 651 protruding from the bottom is pushed up from below, the second engagement projection 705P easily gets over the engagement step 734 of the engagement groove 733, and again the first engagement projection 705D. And the second engaging projection 705P can return to the engaged posture, that is, the temporary holding state, with the engaging stepped portion 734 interposed therebetween.

  After connecting and sealing as described above, the breaking screw 651 and the housing member 687 cannot be removed together with the breaking screw loading portion 724 of the second sealing portion 709 and the screw of the first sealing portion 708. The receiving portion 710 is fastened and fixed. In this state, the accommodating member 687 is held at the innermost innermost portion of the breaking screw loading portion 724. At this time, the elastic engagement of the accommodating member 687 is performed as described above. The piece 705 and the flexible portion 690 are engaged with and engaged with the engagement groove 733 and the flexible portion fitting groove 735 of the breaking screw loading portion 724, respectively. In particular, the elastic engagement piece 705 of the housing member 687 is The engagement is surely engaged in the engagement groove 733 of the breaking screw loading portion 724 with an urging force by elasticity. Furthermore, not only this engagement structure, but also a flat surface portion 705S where the elastic engagement piece 705 in the housing member 687 protrudes and a flat surface portion 733S where the engagement groove 733 in the breaking screw loading portion 724 is recessed. It is in the state fitted as a whole. Therefore, the housing member 687 is held in a state in which it is difficult to rotate within the breaking screw loading portion 724 by the above-described engagement structure and fitting structure, and thereby the breaking screw 651 is illegally reversely rotated from the outside together with the housing member 687. It is more difficult to remove it.

  Thereafter, when the connection sealing between the first component member 706 and the second component member 707 is released for inspection or the like, the bracket 716 and the four bridging portions at the first sealing portion 708 in the connection sealing state. All the parts 723 are cut with a nipper or the like to separate the screwed part 710 from the first component member 706 and the outer frame part 711, and the bracket 729 is cut with a nipper or the like at the second sealing part 709, Separated from the inner frame portion 727, the screwing portion 710 and the broken screw loading portion 724 are removed by pulling them upward or downward from the first sealing portion 708 and the second sealing portion 709. Next, the first component member 706 and the second component member 707 are slid so as to be shifted from each other and removed.

  In the case where the first component member 706 and the second component member 707 are connected and sealed again, any one of the remaining three sets of the screwed portion 710 and the broken screw loading portion 724 is used, and the above-described procedure is performed. In the same manner as described above, connection sealing is performed. At this time, as described above, the breaking screw 651 used for the second and subsequent times is already temporarily held by the breaking screw loading portion 724 of the second sealing portion 709, and it is not necessary to prepare it separately. The screwing operation of the screw 651 can be performed easily and smoothly as in the case of the first connection sealing.

  Needless to say, each time the connection sealing and the release thereof are repeated, the set of the screwing portion 710 and the breaking screw loading portion 724 is removed one by one from among the four sets. 708 and the second sealing portion 709 finish the function of the connection sealing portion by 1/4, in other words, as the connection sealing portion in the first sealing portion 708 and the second sealing portion 709. The area that can be functioned decreases by 1/4, and this also means that the area that is functionally unnecessary increases by 1/4. Since the outer frame portion 711 and the inner frame portion 727 remain unchanged at any point in time, the end portions of the first component member 706 and the second component member 707 at the time of the second and subsequent connection sealing Position to align Functions as a structural member for restricting the sliding movement while Align holds without err decrease subsequently.

  Further, at the stage of manufacturing and transporting the pachinko machine 10, as described above, the breaking screw 651 is connected and sealed at any one of the breaking screw loading portions 724 of the second sealing portion 709 in total of four locations. In the remaining three places, the breaking screw 651 is temporarily held and is in an unused state. For example, when the pachinko machine 10 is removed from the hall and discarded, the three unused places are still broken. If there is a portion where the screw 651 is temporarily held without being used, the unused broken screw 651 and the housing member 687 are taken out and reused in another new pachinko machine. You can also.

(Operation in the eighth embodiment)
As described above, according to the eighth embodiment, the accommodating member 687 is formed by combining the first divided portion 688 and the second divided portion 689, which are a plurality of divided bodies, that is, two divided bodies. ), I.e., the head 652 and a part of the shaft portion 653 are covered, so that it can be attached to the breaking screw 651 more easily. For example, in the case of a housing member that is essentially integrally configured without being divided into a plurality of divided bodies in this way, it takes some effort to make it possible to store the breaking screw without dropping off. . Specifically, for example, in the case of a cylindrical housing member, the breaking screw should not be dropped by a method such as deforming the end portion inside after loading the breaking screw inside, or covering with a member. Need to be accommodated. On the other hand, in the housing member 687 of the eighth embodiment, the breaking screw 651 can be housed without dropping inside by combining the first divided portion 688 and the second divided portion 689 that are a plurality of divided bodies. Therefore, it can be easily and reliably attached to the breaking screw 651 without using a method such as deformation or a lid as described above.

Further, since the first divided portion 688 and the second divided portion 689 are mounted so as to cover the breaking screw 651 from the side, they have an internal shape that closely follows the shape of the breaking screw 651. The housing member 687 is configured, and thereby the breaking screw 651 is more reliably protected. In the case of the breaking screw 651, a small-diameter breaking portion, that is, a small-diameter portion 656 is formed in the middle portion of the head portion 652, and has a shape having undulations unlike a general screw. In such a case, if the internal shape follows the undulating shape of the breaking screw 651, it becomes difficult to insert the breaking screw 651 therein, so that a sufficient space for inserting the breaking screw 651 is secured. Therefore, it is necessary to have an internal shape that extends in a cylindrical shape without undulations. On the other hand, the accommodating member 687 of the eighth embodiment has an internal shape that closely follows the shape of the breaking screw 651, so that the breaking screw 651 can be accommodated without forming a gap as much as possible. Therefore, since there is no room for allowing sufficient movement of the breaking screw 651 inside the housing member 687, erroneous breakage can be more effectively prevented.
In addition, for example, when the end of the housing member is deformed inward after the breaking screw is loaded inside as described above, the breaking screw is erroneously broken by the force applied for the deformation of the housing member. On the other hand, if the configuration is such that the breaking screw 651 is covered from the side as in the case of the housing member 687 of the eighth embodiment, a force that may cause a false breakage is broken. The housing member 687 can be attached without being applied to the screw 651.

  Further, since the first divided portion 688 and the second divided portion 689 are configured to be openable and closable, they can be attached to the breaking screw 651 more easily and reliably. For example, a plurality of divided bodies constituting the housing member may be separated from each other, and the broken screws may be accommodated inside by combining the divided bodies. It is also necessary to align the positions), and if the divided bodies to be combined are asymmetrical, it is necessary to prepare and handle the corresponding divided bodies as a set without fail, whereas the housing member 687 of the eighth embodiment described above If it is a structure, it is also unnecessary to pay attention to alignment and combinations of divided bodies.

  In addition, since the first divided portion 688 and the second divided portion 689 are integrally formed so as to be continuous via the flexible portion 690, the housing member that can be easily formed with a simple configuration 687.

  Further, a boundary line B1 between the first divided portion 688 and the second divided portion 689 extends so as to avoid the upper end surface of the accommodating member 687, that is, the operation hole 701 formation end surface, and appears on the operation hole 701 formation end surface. Therefore, when the breaking screw 651 is screwed, the entire boundary line B1 between the first divided portion 688 and the second divided portion 689 is the broken screw loading portion 724 of the second sealing portion 709. Therefore, it is difficult to perform an unauthorized operation such as inserting a screwdriver or the like into the boundary line B1 from the outside and removing the accommodation member 687 by rotating it backward.

  In addition, the first divided portion 688 and the second divided portion 689 are configured to be engaged and fixed in a closed state by an engagement mechanism including the engagement protrusions 693 and the engagement protrusions 692. Can be easily attached to the breaking screw 651 without requiring a fixing means or a tool, and can be fixed in a closed state without applying a large force, so that erroneous breaking of the breaking screw 651 is more effective. Can be prevented.

  Further, since the breaking screw 651 fitted with the housing member 687 is screwed in a state of being surrounded by the peripheral wall of the breaking screw loading portion 724, the screwed breaking screw 651 and the housing member 687 are externally attached. It is difficult to turn it off and remove it.

  In addition, since a gap is not substantially formed between the housing member 687 and the peripheral wall of the breaking screw loading portion 724, the screwed breaking screw 651 is illegally rotated from the outside together with the housing member 687. It is more difficult to remove it.

  Further, the breaking screw 651 fitted with the accommodating member 687 is screwed in the state surrounded by the upper peripheral wall 713F in addition to the peripheral wall of the breaking screw loading portion 724, that is, in the state surrounded by the double peripheral wall structure. Therefore, it is more difficult to remove the screwed break screw 651 together with the housing member 687 by illegally rotating it backward from the outside. In other words, the breaking screw 651 has a structure surrounded by a triple if the accommodation member 687 is also combined, so that it is more difficult to carry out illegal acts from the outside.

  Further, since the peripheral wall of the breaking screw loading portion 724 has a greater depth in the axial direction than the housing member 687, the screwed breaking screw 651 together with the housing member 687 is illegally rotated from the outside and removed. It has become more difficult. Further, the breaking screw 651 fitted with the accommodating member 687 can be screwed in such a manner that the breaking screw loading portion 724 moves inward along the axial direction, so that the breaking screw loading portion 724 functions as a guide. Thus, the screwing operation is easy to perform.

  Further, since the depth of the peripheral wall of the breaking screw loading portion 724 is substantially equal to the entire length of the breaking screw 651, the breaking screw 651 equipped with the housing member 687 can be accommodated in the threading standby posture. Therefore, the breaking screw 651 can be screwed in from the waiting state for screwing in while being guided inward along the axial direction by the breaking screw loading portion 724, thereby making the screwing operation easier.

  The depth of the peripheral wall of the breaking screw loading portion 724 may be larger than the total length of the breaking screw 651. According to this, an illegal operation is applied to the screwed breaking screw 651 from the outside. There is also an advantage that can be made more difficult. However, the depth exceeding the total length of the breaking screw 651 occupies that much space, and as this depth becomes excessive, the breaking screw 651 becomes more difficult to screw in. Therefore, as in the eighth embodiment, loading the breaking screw Desirably, the depth of the peripheral wall of the portion 724 is substantially equal to the entire length of the breaking screw 651.

  Further, the engagement groove 733 having the engagement step portion 734 is formed in the fracture screw loading portion 724 with the first engagement protrusion 705D and the second engagement protrusion 705P that can be engaged with the engagement step portion 734. The elastic engagement pieces 705 are respectively provided on the accommodation members 687, and the engagement grooves 733 and the elastic engagement pieces 705 constitute a temporary holding mechanism that temporarily holds the breaking screw 651 on which the accommodation member 687 is mounted at a predetermined position. As a result, the breaking screw 651 fitted with the housing member 687 can be temporarily held in a predetermined position in advance, thereby making it possible to perform the connecting and sealing work more easily. That is, for example, in the manufacturing stage of a gaming machine, if the breaking screw 651 fitted with the housing member 687 is temporarily held as a spare, the connection sealing is released for inspection and the like and the connection sealing is performed again. Even in the case of stopping, there is no need to newly prepare the breaking screw 651 fitted with the housing member 687, or a space or mechanism for accommodating the breaking screw 651 fitted with the housing member 687 as a spare is separately provided. There is no need to provide it.

  Further, since the temporary holding mechanism temporarily holds the breaking screw 651 fitted with the housing member 687 in the threading standby posture, the temporary holding mechanism is screwed as it is without adjusting the position of the temporarily holding breaking screw 651. This makes the screwing operation easier.

  In addition, the temporary holding mechanism has an engagement groove 733 extending along the axial direction of the breaking screw 651 and an elastic engagement piece 705 that fits into and engages with the engagement groove 733. Since the engagement mechanism that restricts the rotation of the member 687 is configured, it is more difficult to remove the screwed break screw 651 together with the housing member 687 by illegally rotating it from the outside.

  In addition, since the elastic engagement piece 705 is configured to elastically engage with the engagement groove 733, an engagement mechanism that can be more reliably engaged is configured.

  In addition, the housing member 687 has a flat surface portion 705S as an irregular portion deviating from the circumferential surface on a part of the circumferential surface of the substantially cylindrical shape, and the breaking screw loading portion 724 is a substantially cylindrical shape of the housing member 687. The flat surface portion 733S corresponding to the flat surface portion 705S of the storage member 687 is provided on the inner peripheral surface corresponding to the peripheral surface of the storage member 687, and the rotation of the storage member 687 is restricted by fitting the flat surface portions 705S and 733S to each other. Since the fitting mechanism is configured, it is more difficult to remove the screwed breakage screw 651 together with the housing member 687 by illegally rotating it from the outside.

(8) (Ninth embodiment)
49 and 50 are side views showing still another example of the housing member. The housing member 738 shown in the figure has the same configuration as the housing member 687 in the eighth embodiment except for the configuration of the upper end portion, and the first sealing portion 708 and the first sealing portion in the eighth embodiment. The two sealing portions 709 can be used in the same manner, and therefore the description of the configuration and usage other than the upper end portion will be omitted.

  The housing member 738 in the ninth embodiment is broken by combining the first divided portion 739 and the second divided portion 740 that are a plurality of (two) divided bodies, similarly to the housing member 687 in the eighth embodiment. The screw 651 is configured to cover at least a part (a part of the head part 652 and the shaft part 653) excluding the engaging part (screw hole), but the upper end part is a disk-like shape in the eighth embodiment. It is different from the housing member 687 in the eighth embodiment in that it is not integrally formed like the top plate portion 688T but is divided and formed with most of the lower part thereof. That is, the accommodating member 738 in the ninth embodiment includes a first semi-cylindrical first divided portion 739 and a second divided portion each having a shape obtained by vertically dividing the substantially cylindrical body into two parts including the upper end portion. 740, and the first divided portion 739 and the second divided portion 740 are substantially semi-cylindrical bodies that are substantially symmetrical. In this configuration, a circular operation hole 743 is formed on one end surface in the same manner as in the above embodiments, but this operation hole 743 is also divided. That is, in each of the first divided portion 739 and the second divided portion 740, semicircular cutout portions 744 and 745 are formed at the centers of the opposing edges of the upper surface wall, that is, the wall constituting the operation hole 743 forming side end surface. When the first divided portion 739 and the second divided portion 740 are brought together, the notches 744 and 745 are united to form a circular operation hole 743.

  According to the configuration of the housing member 738 in the ninth embodiment, the boundary line B2 between the first divided portion 739 and the second divided portion 740 extends from the lower end of the housing member 738 to the upper end along one side surface, and at the upper end. Folds at right angles toward the center (axis) of the housing member 738, extends radially to the other side along the upper end surface, that is, the end surface on the operation hole 743 formation side, and then folds downward at a right angle to the lower end along the other side. It extends. That is, the boundary line B2 between the first divided portion 739 and the second divided portion 740 extends so as to penetrate the upper end surface of the housing member 738, that is, the end surface on the operation hole 743 formation side, thereby forming the operation hole 743. It appears on the end face. For this reason, even in the breaking screw loading portion 724, the boundary line B2 is exposed to the outside from the opening of the breaking screw loading portion 724. For example, a driver or the like is inserted into the boundary line B2 from the outside to accommodate the housing member 738. From the standpoint of preventing fraud, the boundary line B1 is the upper end surface of the housing member 687, that is, the operation hole 701, as in the housing member 687 in the eighth embodiment. It is desirable not to appear on the forming side end face. However, in other respects, the storage member 687 in the eighth embodiment can function exactly the same.

(9) (Tenth embodiment)
FIG. 51 is a side view showing still another example of the housing member. The housing member 746 shown in the figure has the same configuration as the housing member 687 in the eighth embodiment except for the configuration of the elastic engagement piece 747, and the second sealing portion 748 shown in the drawing. Has the same configuration as the second sealing portion 709 in the eighth embodiment except for the configuration of the engaging step portion 750 of the breaking screw loading portion 749, and the first sealing in the eighth embodiment. It can be used in the same manner as the unit 708, and therefore the description of the same configuration unit and usage as in the eighth embodiment will be omitted.

  In the tenth embodiment, the elastic engagement piece 747 of the housing member 746 has an upper end side surface (a surface facing the fixed end side of the elastic engagement piece 747) of the first engagement projection 747D that is lowered from the inside to the outside. The lower end side surface (the surface facing the free end side of the elastic engagement piece 747) is formed in an inclined slope shape, and the first engagement protrusion 705D of the elastic engagement piece 705 in the housing member 687 of the eighth embodiment. Similarly to the case, the first engaging protrusion 747D is formed in a slope shape that is inclined upward from the inner side to the outer side. Therefore, the upper edge and the lower edge are inclined downward and upward, respectively, from the inner side to the outer side. It has a trapezoidal side shape in which the other two sides form a vertical side, and is a protrusion that projects while tapering outward.

  The engaging step portion 750 of the breaking screw loading portion 749 in the second sealing portion 748 of the tenth embodiment has an upper surface inclined downward from the inner back to the outer side (to the center side of the breaking screw loading portion 749), And a lower surface inclined to the outside from the inner back to the outer surface, and the lower end side slope of the first engagement protrusion 747D in the elastic engagement piece 747 of the housing member 746 is formed on the upper surface. The first engaging projection 747D can be smoothly guided downward along the lower surface while being smoothly guided downward along the lower surface. Further, the breaking screw loading portion 749 is slightly shorter (in the axial direction) than the breaking screw loading portion 724 of the second sealing portion 709 in the eighth embodiment.

  When inserting the breaking screw 651 fitted with the housing member 746 into the breaking screw loading portion 749 of the second sealing portion 748 from the shaft portion 653 side, as shown in FIG. When it is inserted until it is accommodated in the loading portion 749, the first engagement protrusion 747D of the elastic engagement piece 747 reaches the engagement step portion 750, and the engagement step portion 750 is guided to the downwardly inclined upper surface. As a result, the body moves over while being elastically deformed inward, and the first engagement protrusion 747D and the second engagement protrusion 747P are engaged so as to sandwich the engagement step portion 750. Thereby, the breaking screw 651 fitted with the housing member 746 is temporarily held at a height position where the upper end thereof is aligned with the upper end of the breaking screw loading portion 749.

  At this time, as described above, the breaking screw loading portion 749 is slightly shorter (in the axial direction) than the breaking screw loading portion 724 of the second sealing portion 709 in the eighth embodiment. Then, as shown in FIG. 51, the protruding amount P1 of the tip portion of the shaft portion 653 of the breaking screw 651 penetrating through the shaft insertion hole 751 of the breaking screw loading portion 749 and projecting downward from the lower wall 752 is It is larger than in the case of the embodiment. At this time, if the tip end of the shaft portion 653 is pushed up from below, the first engagement protrusion 747D of the elastic engagement piece 747 is guided by the lower surface of the engagement step portion 750 inclined upward, and is elastically deformed inward. As a result, the temporary holding state due to the engagement between the engagement step portion 750 and the first engagement protrusion 747D is released, and the upper end portion of the housing member 746 protrudes above the upper end of the breaking screw loading portion 749. In this state, the breaking screw 651 can be taken out from the breaking screw loading portion 749. As a result, the breaking screw 651 can be easily removed from the breaking screw loading portion 749 as needed at the stage before use.

  At this time, if the tip of the shaft portion 653 of the breaking screw 651 protrudes below the lower wall 752 of the breaking screw loading portion 749 as described above, the protruding portion is intended by, for example, some impact during handling. Although there is a possibility that the temporary holding state is accidentally released by being pushed up, a protrusion 753 is formed on the lower surface of the lower surface wall 752 of the breaking screw loading portion 749, and the protrusion 753 is formed by the breaking screw. The protruding portion of the shaft portion 653 in 651 is formed so that the protruding height (protruding amount P1) is substantially equal, so that the protruding portion of the shaft portion 653 is intended even when subjected to some impact or the like. It is prevented from being pushed up all the time.

  In the configuration of the tenth embodiment, the upper end side surface (the surface facing the fixed end side of the elastic engagement piece 747) of the second engagement projection 747P in the elastic engagement piece 747 of the housing member 746, and the breaking screw The bottom surface of the engagement step portion 750 in the loading portion 749 is sloped. For example, if both of these surfaces are horizontal, these both surfaces are engaged after the breaking screw 651 is screwed. Since it is difficult for the housing member 746 to move outward from this position, it is further desirable to prevent the breaking screw 651 from being removed illegally.

  (10) As in the eighth to ninth embodiments, when the housing members 687 and 738 are divided into a plurality of divided bodies, for example, there are three such as vertically dividing the cylindrical body into three equal parts. You may make it divide | segment and comprise in the above division body, However, A structure is simpler and shaping | molding is easier if it is divided into 2 parts. Further, for example, the cylindrical body may be divided and divided so as to be cut along a plane perpendicular to the axial direction. However, according to this, the breaking screw can be inserted into the inside. Since it is necessary to form a gap and the divided bodies are connected to each other in the axial direction, if they are not firmly joined, it becomes easy to separate with use.

  Further, as in the eighth to ninth embodiments, the housing members 687 and 738 are held in a closed posture by an external structure such as the fracture screw loading portion 724 of the second sealing portion 709. The plurality of divided bodies constituting the housing member may be separated from each other without being connected to each other, and the broken screws may be housed inside by combining these divided bodies. Even if the divided members are not fixed to each other by the posture, as long as the divided members are held in a closed posture by the external structure as described above, they are equivalent to the housing members 687 and 738 of the eighth to ninth embodiments. Can function. That is, in this case, a connecting structure such as the flexible portion 690 in the housing member 687 of the eighth embodiment and a fixing means such as an engagement mechanism including the engagement protrusions 693 and the engagement protrusions 692 are omitted. You can also.

  The housing member divided into a plurality of divided bodies as in the eighth embodiment to the ninth embodiment may be formed of an inorganic material such as a metal other than the resin, In addition to a cylindrical body like this, any shape such as a rectangular shape like a rectangular parallelepiped may be used.

  (11) In any of the first to ninth embodiments described above, the housing member serving as a protective member covers the head 652 of the breaking screw 651 from the side operated by the driver DR1 (that is, an operation hole is formed). However, such a wall may not be provided, and if it is configured to cover at least a part excluding the screw hole that is the engaging portion, it is necessary as a protective member. Can play a function. For example, it may be a cylindrical protective member (not shown) that covers the small-diameter portion 656 (or the tapered portion 654T), preferably the entire separation portion 654 from the periphery.

(12) In the first embodiment, the first control board box 201A and the connection mounting base member 430 are connected and sealed using the breaking screw 651, and in addition, the cover member 501 and the ball assembly plate 460 are connected. Although it is connected and sealed using the same breaking screw 522, the breaking screw can be used for a connecting portion of any member constituting the gaming machine.

  Among these, the connecting portion between the first case and the second case constituting the main control board box, the connecting portion between the payout board box and the connecting mounting base member, and the first case and the second constituting the payout board box Connection part with case, Connection part between mounting base member and ball assembly plate, Attachment part of payout mechanism part, Pitch detection sensor of winning device corresponding to starting port, and winning device corresponding to big winning port Examples include an entrance detection sensor, a relay board mounting portion that relays the solenoid and the main control board, and the like, all of which are prone to fraud, and it is particularly desirable to use a break screw.

  The payout mechanism section is provided with a payout motor or the like, and an illegal act such as making an unauthorized modification to a substrate that controls the payout motor and excessively driving out the payout motor to pay out excessive prize balls. Since it is easy to be made, a break screw is preferably used for mounting a box (or cover member) for housing the payout motor. In addition, the relay board is mounted on a ball assembly plate (a pedestal formed thereon) or the like and fixed by screws, for example, as in the first embodiment. Since it is difficult to reveal even if fraudulent acts are made, it is easy to be fraudulent, for example, to hide the pseudo main board etc. between the ball assembly board (or pedestal), so this relay board is fixed using a break screw By doing so, countermeasures against fraud can be easily taken.

(13) (Eleventh embodiment)
FIG. 52 is a perspective view showing still another example of the housing member. The housing member 754 shown in the figure is formed by molding a metal material in the same manner as the housing member 621 of the first embodiment, but the housing member 621 of the first embodiment is substantially cylindrical. In contrast to the shape, the housing member 754 of the eleventh embodiment has a substantially hexagonal columnar outer shape with a substantially regular hexagonal cross section. As shown in FIGS. 53 to 55, the breaking screw 755 to which the accommodating member 754 of the eleventh embodiment is attached is similar to the breaking screw 439 in the second embodiment on the head body 755B. Is formed. 55 has a thickness t11 of 2.0 mm, a radius r11 of the collar 756 of 8.0 mm, and a distance from the side surface (lower surface in FIG. 55) of the collar 756 to the tip of the shaft 757. d11 is 14.5 mm, and the diameter r12 of the shaft portion 757 is 3.15 mm.

  As shown in FIGS. 52 and 54, the accommodating member 754 of the eleventh embodiment is continuously formed with an operation hole 758 and a flange portion accommodating cavity 759 similar to those of the accommodating member 621 of the first embodiment. However, as shown in FIG. 54, a flange housing cavity 760 capable of housing the flange 756 of the breaking screw 755 with a slight gap is formed under the flange housing cavity 759. The flange housing cavity 760 has a depth h11 of 2.0 mm and an inner diameter r13 of 8.4 mm. The flange 756 of the breaking screw 755 has a gap of 0.75 mm in the direction of the inner diameter r13 without a gap in the depth h11 direction. It can be accommodated with a gap of 2 mm. Further, the total length L11 in the axial direction of the housing member 754 shown in FIG. 54 is 7.95 mm. That is, the accommodating member 754 according to the eleventh embodiment is configured to accommodate the breaking screw 755 with as little gap as possible. As described later, when the breaking screw 755 is screwed in, the distal end of the shaft portion 757 is configured to be difficult to shift with respect to the screwing position.

  56 to 58 show the connection and sealing of the connecting portion between the first case and the second case constituting the main control board box using the breaking screw 755 to which the housing member 754 of the eleventh embodiment is attached. An example is shown. As in the case of the first control board box 201A according to the first embodiment, the first control board box 201M shown in the figure is an outer case having a relatively large volume so as to sandwich the control board of the main controller. 70M is closed from the rear side of the gaming machine, and the inner case 85M corresponding to the lid is closed from the front side of the gaming machine, and is a rectangular shape that is roughly horizontally long when viewed from the front. It is a box-shaped body having a flat outer shape.

  FIG. 56 is a front view of the first control board box 201M viewed from the front, and therefore corresponds to a view viewed from the rear of the gaming machine when installed in the gaming machine. 57 and 58 show a state in which the first control board box 201M is lying on its front, that is, a posture in which the thickness direction coincides with the vertical direction with the front and back faces upward and downward, respectively. It is a figure which shows a condition. In the following description, basically, the direction in FIG. 56, that is, the direction when the first control board box 201M is installed in the gaming machine from the rear (the vertical direction coincides with the vertical direction of the gaming machine). However, the description is based on the front / rear / left / right direction reversed with respect to the front / rear / left / right direction of the gaming machine).

  One short edge portion (left edge portion in FIG. 56) of the first control board box 201M is rotatable (in a hinge shape) around a vertical axis through a predetermined mounting structure (not shown). The first control board box 201M is pivotally supported so as to be openable and closable (hereinafter, the short edge portion of the first control board box 201M is referred to as “the pivot side edge”). Part)). A shaft support side sealing portion 761 is provided at the shaft support side edge of the first control board box 201M. The shaft support side sealing portion 761 is integrally formed on the shaft support side edge portion of the outer case 70M so that four metal fitting insertion portions 761C projecting in a substantially rectangular parallelepiped shape are juxtaposed at intervals. A slit penetrating in the front-rear direction is formed at the tip of the portion 761C, and a sealing metal fitting (not shown) made of a piece of metal plate with an engagement hole formed in the end is inserted into the slit to the inside. Then, the engagement hole is engaged with the engagement piece disposed at the corresponding position of the inner case 85M, and thus the sealing metal fitting is held so as not to be disengaged by the posture inserted into the interior of the slit. . The outer case 70M and the inner case 85M are fitted and closed by sliding each other in the length direction (left-right direction in FIG. 56), so that the sealing metal fitting cannot be detached from the slit of the metal fitting insertion part 761C as described above. By inserting, the sealing metal fitting functions like a punch, and the outer case 70M and the inner case 85M become non-slidable and are connected and sealed in a closed state.

  The other short edge portion of the first control board box 201M, that is, the short edge portion on the opposite side to the shaft support side edge portion (right edge portion in FIG. 56; hereinafter, also referred to as “free end side edge portion”) is sealed. A portion 762 is provided. The seal sealing portion 762 integrally forms an extending piece extending in the form of a vertically long rectangular ear at the free end side edge of each of the outer case 70M and the inner case 85M, and the outer case 70M and the inner case When the extension piece of the outer case 70M and the extension piece of the inner case 85M overlap with each other when the 85M is in the closed state, a seal seal is applied so as to straddle both extension pieces. When the control board box 201M is illegally opened, the seal is broken and a trace is left. The seal sticker used here has an IC chip and an antenna built in, and is configured to be able to send and receive radio waves with the outside. Can be detected more easily and reliably. Further, a lever member extending along the length direction of the extension piece is interposed between the extension pieces while being pivotally supported at one end (upper end in FIG. 56). The other end of the lever member (the lower end in FIG. 56) is provided with a knob portion 763 formed in an annular shape so that the tip portion can pass through the finger so as to protrude in the same direction as the extending direction of the extending piece. It has been. Further, a cover member 764 is fitted and fixed so as to cover this from the outside in a state where a seal seal is attached to both extending pieces with the lever member interposed therebetween. The cover member 764 has a substantially vertically long rectangular parallelepiped shape that can accommodate the extension piece with the seal attached therein, and has one side surface (the left side surface in FIG. 56) facing the first control board box 201M entirely. It is an open box-shaped cap-shaped member. The inside of the cover member 764 is configured to engage with the knob member 763 side end (lower end in FIG. 56) of the lever member (not shown). With this configuration, after the cover member 764 is once fitted to the extended piece to which the seal is attached, the cover member 764 is removed, so that the lever member is always pulled out. Since the sealed seal that has been used cannot maintain its original shape, unauthorized opening can be detected easily and reliably.

  A screw fixing portion 765 is provided at one end portion (the upper end portion in FIG. 56) of the free control side edge of the first control board box 201M. The screw fixing portion 765 extends from one end portion (the upper end portion in FIG. 56) on the free end side end surface of the outer case 70M with two horizontal pieces that are parallel to each other at an interval, and both horizontal pieces are extended ends. Continuing in a circular arc shape when viewed from the front, a longitudinal piece is integrally built between both lateral pieces slightly inside the arc-shaped portion, and thus, the front end has a D-shape when viewed from the front. A screw insertion portion surrounded by a wall is formed. The inner back portion of the screw insertion portion is closed by a wall, and a screw insertion hole is formed in the inner back wall. By inserting a screw into the screw insertion hole from the front side and screwing it into a corresponding portion of the inner case 85M, the outer case 70M and the inner case 85M are fixed with screws at the corner (upper right corner in FIG. 56). The The screw fixing portion 765 is fixed by a general screw. However, the screw fixing portion 765 may be used with the breaking screw as it is or by attaching an appropriate housing member.

  A break screw insertion portion 766 is provided at the other end portion (lower end portion in FIG. 56) of the free control side edge of the first control board box 201M. As shown in FIGS. 57 and 58, the breaking screw insertion portion 766 includes two horizontal pieces parallel to each other at an interval from the free end side end surface of the outer case 70M, as in the case of the screw fixing portion 765. It extends continuously, while both lateral pieces are bent so as to protrude outwardly at the extended end so as to protrude substantially outwardly in front view, and this inverted character is slightly inside the inverted character. A vertical piece that is bent so as to protrude inward with a generally square shape symmetric to the front part is integrally built between both horizontal pieces, so that the front part has a substantially regular hexagonal shape in front view. A breaking screw loading portion 766H extending in a hexagonal cylindrical shape in the front-rear direction is formed. As shown in FIG. 58, the inner back end face, that is, the rear end face of the fracture screw loading portion 766H is closed by a back wall 766N, and a screw insertion hole 766P is formed in the center of the back wall 766N. A semi-peripheral wall 766S extends rearward from the outer side surface, that is, the rear side surface of the rear wall 766N. The semi-peripheral wall 766S has a distal end direction (a free end side direction of the first control board box 201M) so as to form an arc shape in a front view having a diameter larger than that of the screw insertion hole 766P and smaller than the width of the fracture screw loading portion 766H. Bulges out and closes the tip, and extends to the opposite side along the lateral pieces of the breaking screw loading portion 766H and continues to the outer case 70M. As shown in FIG. As shown in FIG. 3, the front wall is substantially U-shaped, and the peripheral wall is closed at the tip and open on the opposite side.

  In the inner case 85 </ b> M, a breaking screw threaded portion 767 is provided at a position corresponding to the breaking screw insertion portion 766. As shown in FIG. 57, the breaking screw threaded portion 767 extends from the free end side end surface of the inner case 85M in a U-shaped frame shape in a front view, and extends forward in the center of the tip piece. Are formed integrally. As shown in FIG. 58, the cylindrical portion 767S has a length and an outer diameter that can be fitted into the half-circumferential wall 766S of the breaking screw insertion portion 766 with almost no gap, and has a screw hole 767P at the center. Is formed.

  The inner case 85M is provided with a hook-shaped engagement piece (not shown) similar to the engagement piece 706E (see FIG. 43) of the first component member 706 in the eighth embodiment, while the outer case 70M is formed with an engagement groove (not shown) having a bowl-shaped internal shape similar to the engagement groove of the second component member 707 in the eighth embodiment, and the inner case 85M and the outer case 70M. Are fitted to each other so as to engage the engaging piece and the engaging groove. With this configuration, the first control board box 201M allows the outer case 70M to move toward the free end side (lower right in FIGS. 57 and 58) with respect to the inner case 85M, as indicated by an arrow A7 in FIGS. It is closed by sliding it from a position slightly shifted in the direction) and sliding it in the axial support end direction (upper left in FIGS. 57 and 58) until it is aligned with the inner case 85M. As the inner case 85M and the outer case 70M are slid and fitted to each other in this way, as shown in FIG. 57, the cylindrical portion 767S of the breaking screw threaded portion 767 has a breaking screw insertion portion 766. The half peripheral wall 766S is fitted so as to cover from the free end side (lower right side in FIGS. 57 and 58). When this fitting is sufficient, as shown in FIG. 58, the screw insertion hole 766P of the breaking screw insertion portion 766 and the screw hole 767P of the breaking screw insertion portion 767 are coaxially aligned and communicate with each other.

  With the inner case 85M and the outer case 70M fitted as described above, the housing member 754 is attached to the breaking screw loading portion 766H of the breaking screw insertion portion 766 as shown in FIGS. The broken screw 755 is inserted. At this time, as shown in the figure, the first control board box 201M is held in a lying position with the front side facing up, and the breaking screw 755 with the housing member 754 is lowered from right above the breaking screw loading portion 766H. When fitted, it is easy to fit the breaking screw 755 with the accommodating member 754, and is particularly suitable when the breaking screw 755 with the accommodating member 754 is gripped with a gripping tool and fitted into the breaking screw loading portion 766H. Furthermore, in this case, since the accommodating member 754 is formed in a substantially hexagonal column shape as described above, and thus has three sets in total on the side surface thereof, for example, the two surface portions opposed to the gripping tool In the case of having a configuration for gripping the member, it is easy to grip the accommodating member 754 so as to have a posture that matches the breaking screw loading portion 766H, and while maintaining this posture easily and reliably, the holding member 754 can be held up to the breaking screw loading portion 766H. Can be transported and inserted.

  When the breaking screw 755 fitted with the housing member 754 is fitted into the breaking screw loading portion 766H, the outer surface of the housing member 754 is fitted to the inner surface of the breaking screw loading portion 766H as shown in FIG. At this time, the width (space between two side surfaces parallel to each other) T12 of the housing member 754 is 10.0 mm, and the width (space between two opposite surfaces) T13 of the corresponding fracture screw loading portion 766H is 10 mm. 4 mm. Therefore, a gap of about 0.2 mm is secured between each of the six side surfaces of the housing member 754 and the inner side surface of the fracture screw loading portion 766H. This gap is not too small to move the receiving member 754 freely in the direction of its depth (L14; see FIG. 60) within the breaking screw loading portion 766H, while the holding member 754 is substantially free of rattling. Thus, the gap is not excessively large to be held in the broken screw loading portion 766H.

  When the breaking screw 755 with the housing member 754 is further inserted by being inserted into the breaking screw loading portion 766H, the outer surface of the housing member 754 is fitted to the inner surface of the breaking screw loading portion 766H as described above. With this posture, it enters while sliding into the inner part of the breaking screw loading part 766H. As shown in FIG. 60, it is larger than 50% of the total axial length L11 (see FIG. 54) from the end surface (the lower end surface in FIG. 60) of the accommodating member 754 on the side where the shaft portion 757 of the breaking screw 755 protrudes. And when the majority of the length L12 which is smaller than 100%, that is, the majority of the housing member 754 excluding the upper end, enters the breaking screw loading portion 766H, the tip of the shaft portion 757 of the breaking screw 755 is exactly It reaches the inner end (upper end in FIG. 60) of the screw insertion hole 766P in the fracture screw insertion portion 766. That is, the length L13 from the tip of the shaft portion 757 of the breaking screw 755 to the end surface on the operation hole 758 formation side (upper end surface in FIG. 60) of the housing member 754 is slightly smaller than the depth L14 in the breaking screw loading portion 766H. It is set to be large (only a length less than half of the total length L11 of the housing member 754 is greater than 0% and less than 50%).

  With the above configuration, when the tip of the shaft portion 757 of the breaking screw 755 reaches the screw insertion hole 766P in the breaking screw insertion portion 766, most of the housing member 754 has already entered the breaking screw loading portion 766H. The axis of the housing member 754 is correctly determined and held in the posture (that is, the above-described screwing standby posture) positioned on the center of the breaking screw loading portion 766H, that is, the axis of the screw insertion hole 766P. At this time, for example, the dimensions of the breaking screw loading portion or the breaking screw are set so that the tip of the shaft portion of the breaking screw reaches the screw insertion hole when the housing member 754 has not yet reached the breaking screw loading portion. Or, for example, as shown in FIG. 61, the housing member 754 breaks when it has only entered the breaking screw loading portion 768H only slightly (for example, by a depth L15 less than about 50% of the total axial length L11). If the tip of the shaft portion 770 of the screw 769 is set so as to reach the screw insertion hole 768P, the posture of the housing member 754 is still screwed as the entry depth L15 of the housing member 754 is smaller (the approach is shallower). For example, as shown by a broken line in FIG. 61, the posture of the housing member 754 may be inclined with respect to the axis of the screw insertion hole 768P in order not to be surely determined in the waiting state. Easy to shift from the normal of screwed standby posture. When the accommodating member 754 is not properly held in the threading standby posture, if the breaking screw 769 is inserted into the screw insertion hole 768P and is to be screwed into the screw hole 767P of the breaking screw insertion portion 767, the broken line in FIG. As shown, external force is likely to be applied with the tip of the shaft portion 770 of the breaking screw 769 deviating from the screw insertion hole 768P. As a result, the breaking screw 769 is not easily screwed into the screw hole 767P. In addition, an abnormal force is likely to occur due to an abnormal force applied to the small diameter portion 771 of the breaking screw 769. On the other hand, according to the configuration of the eleventh embodiment, as shown in FIG. 60, the breaking screw 755 reaches the screw insertion hole 766P in a state where the housing member 754 is correctly held in the screwing standby posture. The above problems are unlikely to occur.

  As described above, after the tip of the shaft portion 757 of the breaking screw 755 reaches the screw insertion hole 766P, when the breaking screw 755 with the housing member 754 is inserted so as to be further pushed in, as shown in FIGS. The distal end of the shaft portion 757 of 755 is guided by the screw insertion hole 766P and reaches the screw hole 767P of the fracture screw insertion portion 767. At this time, as described above, since the housing member 754 is correctly held in the threading standby posture, the shaft portion 757 of the breaking screw 755 is surely correctly inserted into the screw insertion hole 766P and guided to the screw hole 767P. At this time, the screw insertion hole 766P has a slightly larger diameter than the shaft portion 757 of the breaking screw 755, but the peripheral edge of the end portion is conically expanded to the outside (upper side in FIGS. 62 and 63). Thus, the tip of the shaft portion 757 of the breaking screw 755 is more easily and reliably guided into the screw insertion hole 766P. At this time, as the peripheral edge of the end portion of the screw insertion hole 766P is greatly expanded outward, even if the tip end of the shaft portion 757 of the breaking screw 755 becomes larger, this can be more easily and reliably performed in the screw insertion hole 766P. Can be guided to. However, the diameter-enlarged portion at the end of the screw insertion hole 766P, that is, the flat portion extending around the conical slope portion, that is, the bottom surface in the breaking screw loading portion 766H is a seat that receives the lower surface of the head body 755B of the breaking screw 755 In order to securely fasten the breaking screw 755, it is necessary to secure a sufficient contact area between the lower surface of the head main body 755B of the breaking screw 755 and the seating surface. The larger the diameter of the enlarged diameter portion at the end of the insertion hole 766P, the smaller this contact area. Therefore, the diameter of the enlarged diameter portion at the end of the screw insertion hole 766P (the diameter of the circular ridge line that forms the boundary between the screw insertion hole 766P and the bottom surface of the fracture screw loading portion 766H) is the maximum of the screw insertion hole 766P. It is set to an appropriate size within a range larger than the small diameter and smaller than the diameter of the head body 755B of the breaking screw 755. Specifically, it is about 70% of the diameter of the head body 755B of the breaking screw 755. It has become.

  On the other hand, the end of the screw hole 767P of the breaking screw threaded portion 767 has a shape in which the peripheral edge expands outwardly in a conical shape, and the tip of the shaft portion 757 of the breaking screw 755 is more easily and reliably connected. It is guided by the hole 767P.

  Thereafter, when the breaking screw 755 is screwed into the screw hole 767P to the end and fastened (finally tightened) and rotated at a higher torque, the head of the breaking screw 755 is moved as shown in FIGS. It breaks at the small diameter portion 755N, and the separation portion 755D is separated from the head body 755B.

  By the above operation, the inner case 85M and the outer case 70M are connected and sealed at the breaking screw insertion portion 766. In this way, the first control board box 201M can be sealed in three places, that is, the pivot support side sealing portion 761, the seal sealing portion 762, and the breaking screw insertion portion 766, that is, in a multiple state.

  At this time, as described above, in the breaking screw insertion portion 766, the breaking screw 755 reaches the screw insertion hole 766P in a state in which the housing member 754 is correctly held in the threading standby posture, so that erroneous breakage occurs. The breaking screw 755 can be surely screwed into the screw hole 767P without causing the above.

  Further, after the breaking screw 755 is screwed into the screw hole 767P and the separating portion 755D is separated, the separated portion 755D is separated by the housing member 754 by the housing member 754 as in the case of the first embodiment. By being held at a position between 755B and the operation hole 758, the separating portion 755D becomes an obstacle, and an unauthorized tool cannot reach the head body 755B from the outside. The release is effectively prevented (in FIG. 65, the separation portion 755D is shown in a state of being taken out of the housing member 754, but it goes without saying that the head is actually used. It is held at a position between the main body 755B and the operation hole 758). Further, in the eleventh embodiment, as described above, the substantially hexagonal columnar accommodating member 754 is accommodated in the hexagonal cylindrical rupture screw loading portion 766H with a slight gap and a fitting posture that is substantially free of rattling. Therefore, it is difficult to reversely remove the breaking screw 755 together with the housing member 754. For example, even if the breaking screw 755 to which the housing member 754 is attached is screwed without being surrounded, or is screwed in a state surrounded by a circumferential wall such as a breaking screw loading portion, If there is a sufficient margin between them, for example, when a molten metal such as an adhesive or solder is injected from the operation hole 758 into the housing member 754 and solidified, the separation portion 755D in a separated state is obtained. These are integrated into the head main body 755B together with the housing member 754, and these function as a whole to restore the function of the head of the breaking screw 755, and therefore the breaking screw 755 is rotated in the reverse direction by rotating the separating portion 755D with a screwdriver. Can also be removed. However, according to the configuration of the eleventh embodiment, the housing member 754 is housed in the breaking screw loading portion 766H with the above-described hexagonal fitting posture so that rotation is difficult. Therefore, even if the separating portion 755D is integrated with the housing member 754 and the head body 755B by an adhesive or the like, unless the breaking screw loading portion 766H is broken and the housing member 754 is forcibly opened. It is difficult to reversely remove the breaking screw 755. Therefore, it is possible to more reliably prevent the connected state from being illegally released without leaving a trace.

  In the eleventh embodiment, as described above, the length from the end surface of the housing member 754 on the side where the shaft portion 757 of the breaking screw 755 protrudes is greater than 50% of the total axial length L11 and not more than 100%. When the L12 portion, that is, most of the majority of the housing member 754 enters the breaking screw loading portion 766H, the tip of the shaft portion 757 of the breaking screw 755 is just the inner end of the screw insertion hole 766P in the breaking screw insertion portion 766. 60, that is, the length L13 from the tip of the shaft portion 757 of the breaking screw 755 to the operation hole 758 formation side end surface (upper end surface in FIG. 60) of the accommodating member 754 is the breaking screw loading portion. It is set to be slightly larger than the depth L14 in 766H, but when the tip of the shaft portion 757 of the breaking screw 755 has just reached the screw insertion hole 766P. The depth L14 in the breaking screw loading portion 766H is larger as the penetration depth L12 of the housing member 754 into the breaking screw loading portion 766H is larger, that is, the total length L13 of the breaking screw 755 to which the housing member 754 is attached. Thus, the accommodating member 754 can be more reliably held in the threading standby posture in the broken screw loading portion 766H. From this point of view, the penetration depth L12 of the housing member 754 into the fracture screw loading portion 766H when the tip of the shaft portion 757 of the breaking screw 755 has just reached the screw insertion hole 766P is the total length L11 in the axial direction of the housing member 754. Is more than 50%, more preferably 100% or more. However, if the depth L14 in the breaking screw loading portion 766H is excessive with respect to the total length L13 of the breaking screw 755 to which the housing member 754 is mounted, the breaking screw loading portion 766H occupies more space than necessary, and the breaking screw Since the moving distance of 755 also becomes longer than necessary, the penetration depth L12 of the housing member 754 into the breaking screw loading portion 766H at the time when the tip of the shaft portion 757 of the breaking screw 755 just reaches the screw insertion hole 766P is accommodated. It is desirable that the length of the member 754 is about 200% or less of the total axial length L11, more preferably about 150% or less.

(Operation according to the eleventh embodiment)
According to the configuration of the eleventh embodiment, it has an engaging portion with which an operating tool for performing a rotating operation is engaged, and can be broken and separated when rotated with a torque larger than the torque required for fastening. In the configuration in which the outer case 70M and the inner case 85M of the first control board box 201M can be connected to each other by the breaking screw 755 formed on the head portion of the separation portion 755D as a part, The breaking screw 755 includes a housing member 754 as a protective member that covers at least a part of the separating portion 755D excluding the engaging portion in a state before breaking, and the outer case 70M, which is the constituent member, includes the breaking screw. The shaft portion 757 of the break screw 755 is screwed into the position to be fastened at 755, that is, the break screw insertion portion 766, that is, the break screw screw portion 767. Since the breaking screw loading portion 766H is provided as a guide portion for guiding the child hole 767P, when the shaft portion 757 is screwed into the screw hole 767P when the breaking screw 755 is fastened, the shaft portion 757 By being guided to the screwing position by the breaking screw loading portion 766H which is a guide portion, the shaft portion 757 is accurately screwed into the screwing position with a posture without deviation, and thereby the breaking screw 755 is inserted into the head. It is screwed in such a state that an abnormal external force biased to the part is difficult to be transmitted and an erroneous breakage is hardly caused.

  Further, the housing member 754 has a substantially regular hexagonal outer shape in which a cross-sectional shape in a cross section perpendicular to the axial direction of the breaking screw 755 is non-circular, and a non-circular shape corresponding to the cross-sectional shape of the housing member 754. That is, since the breaking screw 755 is screwed in a state of being fitted in a peripheral wall portion having a hollow portion having a substantially regular hexagonal cross-sectional shape, that is, a breaking screw loading portion 766H, the housing member 754 has a breaking screw. Even if the separated part 755D after separation is integrated with the housing member 754 and the head body 755B by an adhesive or the like, the breaking screw 755 is rotated in the reverse direction in the loading part 766H. It is difficult to remove it. Therefore, it is possible to more reliably prevent the connection state from being illegally released without leaving a trace.

(14) (Tenth embodiment)
FIG. 66 is a front view showing still another example of the breaking screw insertion portion and the sealing structure in the breaking screw insertion portion. The broken screw insertion portion 772 shown in the figure is the same as that of the eleventh embodiment except that the configuration of the broken screw loading portion 772H and a solidified material described later are injected. In the description, the same parts or members as those described above are denoted by the same reference numerals, and the description thereof is basically omitted.

  The breaking screw loading portion 772H according to the tenth embodiment has the same configuration as the breaking screw loading portion 766H in the eleventh embodiment except for the internal front shape. That is, two horizontal pieces parallel to each other with an interval extending from the end surface on the free end side of the outer case 70N, and the extending ends (tip portions) of both horizontal pieces form a substantially regular hexagonal shape in front view. It is molded so as to have an outer shape extending in a hexagonal column shape in the direction. One of the differences between the eleventh embodiment and the eleventh embodiment is that the shape of the hollow portion 772A extending in the axial direction in the fracture screw loading portion 772H is a circular shape when viewed from the front, that is, a circular hole shape. It is.

  The inner diameter R14 of the hollow portion 772A in the broken screw loading portion 772H is slightly larger than the diagonal distance T14 of the housing member 754 in the eleventh embodiment. The difference between the inner diameter R14 of the hollow portion 772A and the diagonal distance T14 of the housing member 754 is not too small to move the housing member 754 freely within the breaking screw loading portion 772H, while the housing member 754 is substantially free. It is a moderate gap that is not excessive to hold in the broken screw loading portion 772H in a posture free from backlash.

  As described above, the housing member 754 is held in the fracture screw loading portion 772H in a posture that is substantially free of rattling, and thus the housing member 754 is placed in a screw-in standby posture as in the case of the eleventh embodiment. The breaking screw 755 can reach a screw insertion hole (not shown) in a properly held state, so that the breaking screw 755 can be surely screwed into the screw hole 767P without erroneous breakage. It has become.

  On the other hand, unlike the case of the eleventh embodiment, the accommodating member 754 can freely move within the circular hollow portion 772A, so that the accommodating member 754 can freely rotate within the hollow portion 772A. Can do. That is, the outer diameter of the rotating track when the housing member 754 is rotated about the axis is equal to the diagonal distance T14, but this is slightly smaller than the inner diameter R14 of the circular hole-shaped hollow portion 772A. Even in the state of being held inside, the housing member 754 can freely rotate around the axis. Thereby, in the manufacturing process, when the breaking screw 755 to which the housing member 754 is attached is fitted into the breaking screw loading portion 772H, it is not necessary to match the rotational position around the axis of the housing member 754. That is, the accommodating member 754 can be fitted into the broken screw loading portion 772H regardless of the rotational position around the axis. Therefore, the break screw 755 with the housing member 754 can be easily fitted into the break screw loading portion 772H, particularly in the case of manual work. There will be no inconvenience of being not properly inserted into 772H.

  However, if the accommodating member 754 can freely rotate in the circular hole-shaped hollow portion 772A as described above, the separating portion 755D may rotate integrally with the surroundings. In some cases, the breaking screw 755 may come off.

  Therefore, in the tenth embodiment, even if the separating portion 755D is integrated with the surrounding as described above, the solidifying material is injected into the breaking screw loading portion 772H loaded with the housing member 754 and solidified in advance. This makes it difficult to rotate the accommodating member 754 relative to the breaking screw loading portion 772H, thereby preventing the breaking screw 755 from rotating backward.

  As the solidifying material, for example, a curable resin can be used. Further, for example, a molten metal (solder or the like) having a melting point lower than the melting point of the resin constituting the fracture screw loading portion 772H can be used.

  As the sealing operation in the tenth embodiment, for example, in the same manner as in the eleventh embodiment, the breaking screw 755 on which the housing member 754 is mounted is inserted into the breaking screw loading portion 772H and screwed. After inserting and fastening (finally tightening), rotating with higher torque to separate the separating portion 755D, the solidifying material is injected and solidified from the gap between the housing member 754 and the fracture screw loading portion 772H. Like that. Accordingly, the housing member 754 and the breaking screw loading portion 772H are integrated, and it is difficult for the housing member 754 to rotate within the breaking screw loading portion 772H. In other words, the gap is filled by injecting and solidifying the solidifying material into the gap between the housing member 754 and the fracture screw loading portion 772H, whereby the circumference of the housing member 754 has the same form as the hexagonal hole. Thus, it can be said that the rotation of the housing member 754 becomes difficult.

(Operation by the tenth embodiment)
According to the configuration of the tenth embodiment, the operation tool for performing the rotation operation has the engagement portion to be engaged and can be broken and separated when rotated with a torque larger than the torque necessary for fastening. In the configuration in which two or more components, that is, the outer case 70N of the first control board box and the inner case can be connected to each other by the breaking screw 755 formed on the head of the separation portion 755D as a part, The screw 755 includes a housing member 754 as a protective member that covers at least a part of the separating portion 755D excluding the engagement portion in a state before breaking, and the housing member 754 is attached to a fracture screw loading portion 772H that is a peripheral wall portion. The break screw 755 is screwed in an enclosed state, and a solidified material is injected and solidified between the housing member 754 and the break screw loading portion 772H. Therefore, the housing member 754 is held in a posture that is difficult to rotate in the breaking screw loading portion 772H, and thereby, it is more sure that the connected state is illegally released by rotating the breaking screw 755 in the reverse direction. It is to be prevented.

  In addition, since the peripheral wall portion, that is, the breaking screw loading portion 772H has a circular hole-like hollow portion that can include the rotation track of the housing member 754, the breakage in which the housing member 754 is attached in the manufacturing process. When the screw 755 is inserted into the breaking screw loading portion 772H, it is not necessary to match the rotational position around the axis of the housing member 754. Therefore, no matter what the rotational position around the axis of the housing member 754 is, it is loaded with the breaking screw. It can be easily and reliably fitted into the portion 772H. At this time, since the housing member 754 can be rotated as it is and the reverse rotation of the breaking screw 755 is allowed, the solidification is made between the housing member 754 and the breaking screw loading portion 772H as described above. A configuration that makes it difficult to rotate the housing member 754 by injecting and solidifying the material is particularly useful.

(15) (13th embodiment)
FIG. 67 is a perspective view showing still another example of the housing member. The housing member 773 shown in the figure is the same as the housing member 754 of the eleventh embodiment except that the housing member 773 includes a lateral hole 773P. Therefore, in the following description, the same parts or members as those described above are used. Are denoted by the same reference numerals, and the description thereof is basically omitted.

  The housing member 773 according to the thirteenth embodiment has a substantially hexagonal columnar outer shape, similar to the housing member 754 according to the eleventh embodiment. 773P is formed and communicates with the internal space of the housing member 773.

  68 and 69 show a state in which the breaking screw 755 to which the housing member 773 according to the thirteenth embodiment is attached is inserted into the breaking screw loading portion 766H similar to the case of the eleventh embodiment. Yes. The sealing operation using the housing member 773 according to the thirteenth embodiment is the same as that of the eleventh embodiment. However, in the thirteenth embodiment, the housing member 773 includes a lateral hole 773P. In addition, since the breaking screw loading portion 766H surrounding the housing member 773 is made of a transparent resin and integrated with the outer case 70M, the situation inside the housing member 773 is determined through the lateral hole 773P. Is visible. Therefore, in particular, it is possible to easily confirm from the outside whether or not the separating portion 755D has been separated after the breaking screw 755 is screwed. Since the separation portion 755D is held in the housing member 773 in substantially the same posture before and after separation, for example, as viewed from the operation hole, it is difficult to determine whether or not the separation portion 755D is separated. Other than the above, it is easy to work if the internal state of the housing member 773 is visible from the surroundings. That is, the lateral hole 773P is a structure mainly for preventing the reverse rotation of the housing member 773 more reliably as will be described later, but can also function as a viewing window for confirming the state inside the housing member 773. It has become a thing. In particular, in the thirteenth embodiment, since the lateral hole 773P is formed in all six side surfaces of the housing member 773, the internal state of the housing member 773 can be viewed from all directions.

  After the breaking screw 755 with the housing member 773 is inserted into the breaking screw loading portion 766H and screwed to separate the separating portion 755D of the breaking screw 755, the housing member 773 and the breaking member are broken as in the tenth embodiment. The solidifying material is injected from the gap with the screw loading unit 766H and solidified. When the solidifying material is injected, as shown in FIG. 70, the solidifying material 774 also flows into the housing member 773 through the lateral hole 773P and fills the fracture screw loading portion 766H so as to straddle the inside and outside of the housing member 773. Solidify in a wet state. Thereby, not only between the housing member 773 and the breaking screw loading portion 766H, but also the internal space of the housing member 773 and the breaking screw 755 are continuously integrated by the solidified material 774 through the lateral hole 773P. Thereby, the reverse rotation of the accommodating member 773 can be prevented more reliably. At this time, if the solidified material 774 is filled and solidified as much as possible inside the breaking screw loading portion 766H, the inside of the breaking screw loading portion 766H is substantially equivalent to a solid. Therefore, the room for unauthorized operation can be reduced as much as possible.

  The solidifying material may be injected from between the head of the breaking screw 755 and the operation hole, for example, in addition to being injected from the gap between the housing member 773 and the breaking screw loading portion 766H as described above. In this case, the solidified material flows into the housing member 773 and flows out of the housing member 773 from the lateral hole 773P. It solidifies in a state of being filled in the portion 766H. However, since there is a case where the space between the head of the breaking screw 755 and the operation hole is narrow and it is difficult to inject the solidified material, it is only necessary to inject from a location where injection is easy. Further, in order to prevent reverse rotation of the housing member 773, it is most necessary to fill and solidify the solidifying material between the housing member 773 and the fracture screw loading portion 766H. It is desirable to inject the solidified material preferentially from the gap with the screw loading portion 766H.

  In the thirteenth embodiment, the opening area of the lateral hole 773P is about 24% of the area of the side surface of the housing member 773. The opening area of the lateral hole 773P is preferably about 20 to 70% of the area of the side surface of the housing member 773. If the opening area of the horizontal hole 773P is smaller than 20%, it is difficult for the solidified material to circulate, or the portion straddling the inside and outside of the housing member 773 becomes small and the strength after solidification becomes insufficient. In addition, the situation inside the housing member 773 becomes difficult to visually recognize when the breaking screw 755 is screwed. On the other hand, if the opening area of the lateral hole 773P is larger than 70%, the strength of the housing member 773 becomes insufficient and the degree of internal exposure becomes excessive. As a result, the protection for protecting the internal fracture screw 755 from external force. The function as a member may be insufficient.

  As the shape of the horizontal hole, for example, an elliptical shape, a long hole shape, a square shape, a polygonal shape, a cross shape, an indefinite shape, etc. can be used. Although it is considered that the shape is desirable, from the viewpoint of workability (ease of formation) and strength, it is desirable to have a circular shape like the lateral hole 773P of the thirteenth embodiment.

  In addition, the effect is obtained if the lateral holes are arranged in at least a part of the housing member, but it is more preferable that the lateral holes are more evenly distributed as much as possible (for example, an angular interval of about 180 ° is provided). 2 places, 3 places with an angle interval of around 120 °, etc.), and more preferably, it is more omnidirectionally arranged like the horizontal hole 773P of the thirteenth embodiment so that the flowability of the solidified material. Further, it is desirable from the viewpoint of the strength after solidification and from the viewpoint of visibility.

  As shown in FIG. 68, the horizontal hole 773P in the thirteenth embodiment has a lower end that is an upper surface portion of the head body 755B of the breaking screw 755, that is, a peripheral edge of a slope portion that expands in a tapered shape from a small diameter portion. It is formed so as to be at almost the same height position (more specifically, to be at a height position that slightly intersects with the upper end of the buttocks accommodation cavity of the accommodation member 773). At this time, the collar housing cavity of the accommodating member 773 has a gap as small as possible between the collar 756 of the breaking screw 755, as in the collar housing cavity 760 of the housing member 754 in the eleventh embodiment shown in FIG. The flange portion accommodating cavity formed on the buttocks accommodating space is similar to the flange accommodating space 759 of the eleventh embodiment. Since it is formed so as to have a cylindrical internal shape, it is constricted between the narrow diameter portion of the breaking screw 755 and the flange portion accommodating cavity so that the small diameter portion is narrowed toward the center side. A space is formed. In other words, the accommodating member 773 of the thirteenth embodiment has as little gap as possible in the collar portion 756 of the fracture screw 755 in the collar portion accommodating cavity, like the accommodating member 754 in the eleventh embodiment. By accommodating in the state, the effect of suppressing the rattling of the breaking screw 755 as much as possible is secured, and conversely, a space is secured in the flange portion accommodating cavity above. Therefore, with this configuration, the injected solidified material continues into the inside and outside of the housing member 773 through the lateral hole 773P, and uses the space between the narrow diameter portion of the breaking screw 755 and the flange portion housing cavity to accommodate the housing member. The inside of the 773 is also fully distributed.

(Operation according to the thirteenth embodiment)
According to the configuration of the thirteenth embodiment, the housing member 773 includes the lateral hole 773P. Therefore, when the solidifying material is injected, the housing member 773 has a peripheral wall so as to straddle the inside and outside of the housing member 773 through the lateral hole 773P. It solidifies in a state of being filled in a certain broken screw loading portion 766H. Thereby, the internal space of the housing member 773 and the breaking screw 755 are continuously integrated with the breaking screw loading portion 766H by the solidified material 774 through the lateral hole 773P. Thereby, the reverse rotation of the accommodating member 773 is prevented more reliably.

  In addition, since the internal state of the housing member 773 can be visually recognized from the periphery through the lateral hole 773P, it is easily confirmed from the outside whether or not the separation portion 755D has been separated, particularly after the breaking screw 755 is screwed. be able to. That is, it is easy to work because the situation inside the housing member 773 is visible from the surroundings except for the operation hole. In other words, the lateral hole 773P can effectively function as a viewing window for confirming the internal state of the housing member 773.

  For example, even when the solidification material is not injected as described above, the breaking screw 755 with the housing member 773 is further enclosed without being surrounded by a peripheral wall-like structure such as a breaking screw loading portion. Even in the case of screwing in a state of being almost entirely exposed, the housing member 773 provided with the lateral hole 773P has the effect of the viewing hole as described above. It can be suitably used for stopping.

(16) (14th embodiment)
In the thirteenth embodiment, the substantially hexagonal column-shaped accommodation member 773 having the lateral hole 773P is inserted into the hexagonal cylindrical fracture screw loading portion 766H similar to the case of the eleventh embodiment. Since the housing member 773 rotates when inserted into the circular hole-shaped hollow portion 772A like the fracture screw loading portion 772H according to the tenth embodiment, the reverse rotation of the housing member 773 is more reliably performed. In particular, the effect of the lateral hole 773P, which is a structure for preventing this, is particularly exerted. FIG. 71 shows an example in which the housing member 773 according to the thirteenth embodiment is inserted into the breaking screw loading portion 775H basically the same as the breaking screw loading portion 772H according to the tenth embodiment.

  In the fourteenth embodiment, as in the case of the thirteenth embodiment, a solidified material (not shown) is straddled in the breaking screw loading portion 775H so as to straddle the inside and outside of the housing member 773 through the lateral hole 773P. By filling and solidifying, the inside of the fracture screw loading portion 775H can be integrated, and the reverse rotation of the housing member 773 can be more reliably prevented. In this case, as in the case of the tenth embodiment, even when the housing member 773 is inserted into the hollow hole-shaped hollow portion, the housing member 773 rotates by injecting and solidifying the solidifying material. In addition, as in the case of the thirteenth embodiment, by using the substantially hexagonal columnar accommodating member 773 having the lateral hole 773P, the inner and outer sides of the accommodating member 773 are straddled. Therefore, the housing member 773 can be more reliably prevented from rotating backward.

  Furthermore, in the fourteenth embodiment, as shown in FIG. 71, groove longitudinal 775G is formed as a plurality of concave portions on the inner peripheral surface of the fracture screw loading portion 775H. In other words, on the inner peripheral surface of the breaking screw loading portion 775H, it is recessed into a rectangular cross section at equal intervals of 60 ° and extends linearly along the depth direction (axial direction) of the breaking screw loading portion 775H. A groove groove length 775G is formed. According to this configuration, the solidification material flows into the groove length 775G and solidifies, so that the reverse rotation of the housing member 773 is further reliably prevented. That is, the solidified material that has flowed into the groove vertical 775G and solidified meshes with the groove vertical 775G, thereby exhibiting an anchor effect, thereby further improving the effect of preventing the housing member 773 from rotating backward. Further, when injecting the solidified material from the gap between the housing member 773 and the breaking screw loading portion 766H, the groove length 775G can also function as a flow path of the solidifying material, and in particular, the groove length 775G is used as the breaking screw loading portion 766H. If it forms so that it may penetrate to the upper end of this, the clearance gap which inject | pours solidification material can be expanded that much.

  In the case of the above configuration, for example, if the corner portion of the housing member 773 comes to the position of the groove length 775G, the groove length 775G may be blocked, making it difficult for the solidified material to flow. Accordingly, for example, the width of the groove length 775G is made larger than the width of the corner portion of the housing member 773, or the groove length 775G is formed in five or seven stripes at the same time at all corner portions of the housing member 773. Or the groove length 775G is formed so as to extend spirally along the depth direction (axial direction) of the fracture screw loading portion 775H. Regardless of the rotational position, the solidified material can be caused to flow into the groove length 775G.

(17) In the tenth embodiment to the fourteenth embodiment, as described above, the solidified material is injected in advance into the fracture screw loading portions 766H, 772H, and 775H loaded with the housing members 754 and 773 so as to be solidified. However, such injection of the solidifying material can be suitably applied to any configuration in which the fracture screw is surrounded by a peripheral wall-like structure. For example, the first embodiment to the first embodiment can be applied. Any of the configurations of the eleventh embodiment can be suitably applied. Particularly, as in the case of the tenth embodiment, for example, at least one of the housing member and the breaking screw loading portion is cylindrical or circular, and the housing member can rotate in the breaking screw loading portion as it is. In some cases, it is useful to inject and solidify the solidified material.

(18) In the eleventh embodiment to the fourteenth embodiment, the housing members 754 and 773 have a substantially hexagonal columnar outer shape having a substantially regular hexagonal cross section. For example, other than this, Even if the cross section has a polygonal shape or an indefinite shape, basically the same effect as in the eleventh embodiment to the fourteenth embodiment can be obtained. Any polygon can be used as the polygon constituting the cross-sectional shape as long as the number of corners is an integer of 3 or more. For example, when forming a housing member by forging a round bar, However, the smaller the number, the greater the amount of deformation required, which is disadvantageous in terms of workability.On the other hand, the larger the number of corners, the smaller the corner projections on the peripheral surface and the closer the shape of the cylinder. This is disadvantageous in making it difficult to rotate. From such a point of view, it is desirable to use, for example, a quadrangular or octagonal shape, especially a hexagonal shape as in the eleventh embodiment to the fourteenth embodiment. In addition, for example, in the case of holding the breaking screw with the holding member with a gripping tool having a configuration for holding the target member by the two opposing face portions and fitting the breaking screw into the breaking screw loading portion, the holding member has two faces parallel to each other. It is easier to grip with a gripper. From this point of view, an even number, for example, a quadrangle, a hexagon, an octagon, etc. is advantageous. On the other hand, the larger the number of corners, the narrower the surface to be gripped by the gripping tool.

  In addition, even if the housing member is basically cylindrical, the housing member can be rotated if, for example, a flat portion, a concave portion, a convex portion, etc. are formed in a part of the housing member so that the outer periphery is not necessarily uniform. In order to make it difficult to achieve this, basically the same effect as the outer shape of the polygonal cross section can be obtained. However, in this case, for example, if the inside of the breaking screw loading part is also shaped partially non-uniformly corresponding to the partially non-uniform outer shape of the housing member, the housing member rotates when fitted into the breaking screw loading part. It takes time and effort to adjust the position.

  Furthermore, even in the case of a cylindrical housing member having a uniform entire circumference, such as the housing member 621 of the first embodiment, it is more desirable that the thirteenth is achieved by the injection and solidification of the solidifying material as described above. As in the case of the embodiment to the fourteenth embodiment, it is possible to make the housing member difficult to rotate by providing a horizontal hole in the housing member and injecting and solidifying the solidifying material.

(19) The break screw may be used to connect two or more components in the manufacturing process of the gaming machine, but may be used in a stage after the manufacturing process of the gaming machine. For example, in a game machine manufacturing process, two or more constituent members are connected by means other than a break screw (for example, a normal screw), and after the connection is released for inspection or the like at a later stage, the relevant configuration It is also possible to use the member by reconnecting the members with a breaking screw. In this case, an unused broken screw can be easily installed and removed at any part of the gaming machine (for example, a locking claw portion is formed integrally with any resin component of the gaming machine, and this The breaking screw is elastically locked to the pawl, etc.), that is, the breaking screw is put on standby at any part of the gaming machine so that it can be used at any stage after the manufacturing process. You may make it leave. In other words, in the present invention, two or more constituent members may be connected with the breaking screws in the manufacturing process, or two or more constituent members may be connected with the breaking screws by waiting for the breaking screws. It is good also as the aspect which is set as the state to obtain, and it can be set as the game machine by which the 2 or more structural member was comprised by the fracture | rupture screw so that connection was possible.

(20) In the first embodiment, the pachinko machine 10 is exemplified, but as the gaming machine, in addition to the pachinko machine, a slot machine and a gaming machine in which the pachinko machine and the slot machine are fused are also exemplified. .

The basic configuration of the slot machine is “variable display means for confirming and displaying the identification information after dynamically displaying an identification information string made up of a plurality of identification information, resulting from the operation of the starting operation means (for example, an operation lever). The dynamic display of the identification information is started, and the dynamic display of the identification information is stopped due to the operation of the operation means for stop (for example, the stop button) or when a predetermined time elapses. The game machine is provided with special game state generating means for generating a special game state advantageous to the player on condition that the confirmed identification information is the specific identification information.
In this case, examples of valuable objects include coins and medals.

  As a basic configuration of a gaming machine in which a pachinko machine and a slot machine are integrated, “a variable display means for confirming and displaying identification information after dynamically displaying an identification information string composed of a plurality of identification information, and a starting operation means ( For example, the dynamic display of the identification information is started due to the operation of the operation lever), the dynamic display of the identification information is caused by the operation of the operation means for stop (for example, the stop button), or when a predetermined time has elapsed. Special game state generating means for generating a special game state that is advantageous to the player on the condition that the display is stopped and the confirmed identification information at the time of the stop is specific identification information, and a ball is used as a valuable object In addition, a gaming machine is configured so that a predetermined number of balls are required at the start of dynamic display of the identification information, and many balls are paid out when a special gaming state occurs. It made.

  Note that this specification discloses all the contents of the invention relating to the following means A1, means B1, means C1, means D1 and means E1 to means E27.

(Problem to be solved by the invention according to means A1)
In a gaming machine such as a pachinko machine using a pachinko ball, for example, for the purpose of obtaining an illegal profit, for example, a control board such as a main control board that controls the game is illegally removed and a ROM (CPU In the case where the ROM is made into one chip, an illegal act such as exchanging the chip) and changing the game content may be performed.

  For this reason, the board box containing the control board is closed with a special screw called a breaking screw, or the board box is attached to a predetermined position with the breaking screw, thereby preventing illegal acts. It has been made to prevent. The breaking screw has a configuration in which a small-diameter breaking portion is formed in the middle portion of the head, and after screwing into the screw hole with a screwdriver and fastening it, when rotated with a larger torque, the breaking screw is located on the tip side from the breaking portion. The part having the screw hole for inserting the screwdriver is broken and separated, so that the screw cannot be subsequently loosened by rotating it backward. By using this breaking screw for closing or attaching the substrate box, it is difficult to open or remove the substrate box, and therefore, illegal acts can be effectively prevented.

  However, since the breaking screw as described above is formed with a breaking portion that is easy to break, for example, particularly when a large amount of external force is placed in one place before performing the fastening operation. In response, the rupture portion may be broken and may become unusable as a screw before being used for fastening (erroneous rupture).

  Therefore, a holder is previously mounted on the head of the breaking screw as a protective member that covers it. According to this configuration, even when a certain external force is applied before the fastening operation, the head of the fracture screw is protected from the external force by the holder, thereby effectively preventing the fracture screw from being erroneously broken. In addition, after breaking the head of the breaking screw, the separated part becomes garbage, and it is necessary to dispose of it, or the separated part enters other parts of the gaming machine and causes trouble. However, if the separated part is held by a holder, these problems can be avoided (see Japanese Patent Application Laid-Open No. 2010-42070).

  However, in addition to the erroneous rupture before the fastening operation as described above, for example, during the fastening operation of the rupture screw, particularly when the shaft portion of the rupture screw is screwed into the screw hole, it is accurately placed on the central axis of the screw hole If it is difficult to screw in while holding the shaft part of the breaking screw so that it is positioned, and if the shaft part of the breaking screw is going to be screwed in a state shifted from the center axis of the screw hole If an abnormal external force that is biased toward the head of the breaking screw is transmitted, erroneous breakage will occur.

  The invention according to means A1 has been devised in view of such a problem, and in a gaming machine using a broken screw, it is possible to reduce the erroneous breakage of the broken screw and perform the fastening operation more reliably. An object is to provide a gaming machine.

Therefore, the gaming machine according to the present invention is as means A1.
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by a screw (breaking screw),
The breaking screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.
The component member has a guide portion that guides a shaft portion of the breaking screw to a screwing position at a place fastened by the breaking screw.

  In the present invention, “connecting two or more constituent members” implies connecting arbitrary members constituting the gaming machine, for example, a control board between the first case and the second case. Connecting the first case and the second case of the board box having the accommodated structure to close the board box, or connecting the board box or the control board itself to a base (mounting base) member to be in a predetermined position. Both fixing and the like are included.

  According to the configuration of the means A1, when the shaft portion is screwed into the screw hole during the fastening operation of the breaking screw, the shaft portion is guided to the screwing position by the guide portion, so that the shaft portion is displaced. Therefore, the breaking screw can be screwed into the screwing position in a state where the external force biased to the head is not easily transmitted and erroneous breakage is unlikely to occur.

In addition, the gaming machine according to the present invention is the means B1.
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by a screw (breaking screw),
The breaking screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.
The protective member has a non-circular outer shape in cross section perpendicular to the axial direction of the breaking screw, and includes a hollow portion having a non-circular cross sectional shape corresponding to the cross sectional shape of the protective member. The rupture screw is screwed in a state of being fitted to the screw.

  According to the configuration of the means B1, the protective member is held in the peripheral wall portion in a posture that is difficult to rotate, and thus, even if the separated portion after separation is integrated with the surroundings, the breaking screw is rotated backward to be removed. It is difficult. Therefore, it is possible to more reliably prevent the connected state from being illegally released without leaving a trace.

  The cross-sectional shape of the protective member is not necessarily non-circular, and may be circular as long as it can come into contact with the peripheral wall when it is rotated. For example, even if the protective member has a circular cross-sectional shape, the breaking screw is held in such a posture that the shaft is located at a position other than the center thereof, that is, the breaking screw is held with the shaft eccentric. For example, even if it is fitted with a slight gap in the peripheral wall portion having a hollow portion having a circular cross-sectional shape corresponding to the circular cross-sectional shape of the protective member, the protective member is protected around the axis of the breaking screw. It is difficult to rotate the member.

In addition, the gaming machine according to the present invention, as means C1,
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by a screw (breaking screw),
The breaking screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.
The breaking screw is screwed in a state where the protective member is surrounded by the peripheral wall portion, and a solidifying material is injected and solidified between the protective member and the peripheral wall portion.

  According to the configuration of the means C1, the protective member is held in a posture that is difficult to rotate in the peripheral wall portion, thereby more reliably preventing the connection state from being illegally released by rotating the breaking screw backward and removing it. Is done.

(Problem to be solved by the invention according to means D1)
In a gaming machine such as a pachinko machine using a pachinko ball, for example, for the purpose of obtaining an illegal profit, for example, a control board such as a main control board that controls the game is illegally removed and a ROM (CPU In the case where the ROM is made into one chip, an illegal act such as exchanging the chip) and changing the game content may be performed.

  For this reason, the board box containing the control board is closed with a special screw called a breaking screw, or the board box is attached to a predetermined position with the breaking screw, thereby preventing illegal acts. It has been made to prevent. The breaking screw has a configuration in which a small-diameter breaking portion is formed in the middle portion of the head, and after screwing into the screw hole with a screwdriver and fastening it, when rotated with a larger torque, the breaking screw is located on the tip side from the breaking portion. The part having the screw hole for inserting the screwdriver is broken and separated, so that the screw cannot be subsequently loosened by rotating it backward. By using this breaking screw for closing or attaching the substrate box, it is difficult to open or remove the substrate box, and therefore, illegal acts can be effectively prevented.

  However, since the breaking screw as described above is formed with a breaking portion that is easy to break, for example, particularly when a large amount of external force is placed in one place before performing the fastening operation. In response, the rupture portion may be broken and may become unusable as a screw before being used for fastening (erroneous rupture).

  Therefore, a holder is previously mounted on the head of the breaking screw as a protective member that covers it. According to this configuration, even when a certain external force is applied before the fastening operation, the head of the fracture screw is protected from the external force by the holder, thereby effectively preventing the fracture screw from being erroneously broken. In addition, after breaking the head of the breaking screw, the separated part becomes garbage, and it is necessary to dispose of it, or the separated part enters other parts of the gaming machine and causes trouble. However, if the separated part is held by a holder, these problems can be avoided (see Japanese Patent Application Laid-Open No. 2010-42070).

  However, if the holder is attached to the head of the breaking screw as described above, the breaking portion of the breaking screw is held in the holder in substantially the same posture before and after the separation, so that it is broken in the fastening operation. When the separation portion of the screw is broken and separated, it is difficult to determine from the outside whether or not the separation portion has been separated. For this reason, the fastening operation is finished in a state where the separating portion is not separated by mistake, and the broken screw can be easily removed by reverse rotation with a screwdriver, that is, in a state where sealing is not performed. It is easy to cause a failure.

  The invention according to means D1 has been devised in view of such problems, and in a gaming machine using a breaking screw, it can be easily confirmed whether or not the separation portion of the breaking screw has been separated. It is an object of the present invention to provide a gaming machine that can perform a fastening operation more reliably.

Therefore, the gaming machine according to the present invention is the means D1,
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by a screw (breaking screw),
The breaking screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.
The protective member includes a lateral hole.

  In the present invention, the term “lateral hole” refers to a direction that is not parallel to the axial direction of the breaking screw that is covered by the protective member (for example, a direction that is perpendicular or inclined with respect to the axial direction of the breaking screw). Means a hole that penetrates a part of the protective member (for example, a part of the side wall, etc.) and communicates with the inside and outside of the protective member.

  According to the configuration of the means D1, the internal state of the protective member can be visually recognized from the surroundings through the side hole. Can be confirmed. That is, it is easy to work because the situation inside the protective member can be seen from the surroundings except for the operation hole. In other words, the lateral hole can effectively function as a viewing window for confirming the situation inside the protective member.

(Problems to be solved by the invention according to means E1 to E27)
Since the rupture screw is formed with a rupture portion that is easy to break, the rupture portion is subjected to some external force, for example, especially when it is placed in a large amount at one place before fastening work. May break and become unusable as a screw before being used for fastening (false breakage).

  Therefore, for example, it is conceivable to prevent the broken screw by storing it in a hard case until it is used, but according to this, it is necessary to take out the broken screw from the case at the time of use. Moreover, since it becomes necessary to handle the case separately after that, the operation becomes troublesome.

  The invention according to means E1 to means E27 has been devised in view of such a problem, and in a gaming machine using a break screw, it is possible to effectively prevent the break screw from being broken and to be fastened. It is an object of the present invention to provide a gaming machine that can be easily operated.

The gaming machine according to the present invention includes means E1,
A separation part, which is a part that can be broken and separated when rotated with a torque larger than the torque required for fastening, having an engagement part to which an operation instrument for performing a rotation operation is engaged, is formed on the head. A gaming machine configured such that two or more components can be connected by a screw (breaking screw),
The breaking screw includes a protective member that covers at least a part of the separating portion excluding the engaging portion in a state before breaking.

  In the present invention, “connecting two or more constituent members” implies connecting arbitrary members constituting the gaming machine, for example, a control board between the first case and the second case. Connecting the first case and the second case of the board box having the accommodated structure to close the board box, or connecting the board box or the control board itself to a base (mounting base) member to be in a predetermined position. Both fixing and the like are included.

According to the configuration of the means E1, even when any external force is applied before the fastening operation is performed, the separating portion is protected from the external force by covering at least a part thereof with the protective member, thereby A false break is effectively prevented.
In addition, since the engaging portion of the separating portion is not covered with the protective member, it is possible to perform the rotation operation by engaging the operating instrument with the engaging portion even when the protective member is provided. The work can be easily performed without the need for extra work such as removing the broken screw or handling the removed protective member separately.

A gaming machine according to the present invention is a gaming machine of means E1, as means E2.
The head part of the breaking screw is located between the separation part, the head body remaining on the shaft part side after the separation part is separated, and the separation part and the head part. It has a structure with a small diameter part smaller than any of the main body, and the separation part is separated by breaking at the small diameter part,
The protective member covers at least the small-diameter portion.

  According to the configuration of the means E2, the broken portion of the breaking screw is more effectively prevented by covering the thin portion, which is the portion where the breaking screw is broken, with the protective member.

Further, the gaming machine according to the present invention is a gaming machine of means E1 or means E2 as means E3.
The protective member covers the whole of the separating part of the breaking screw except for the engaging part.

  According to the configuration of the means E3, the separation part is covered with the protection member in its entirety other than the engagement part, so that it can be more reliably protected from external force, thereby preventing the broken screw from being broken more effectively.

In addition, the gaming machine according to the present invention is a gaming machine according to any one of the means E1 to E3 as the means E4.
The protective member can hold a separation portion of the breaking screw after separation.

  When the fastening work is performed using a break screw, the separated separation part becomes garbage and the processing takes time and time, and the separation part enters from the gap in the gaming machine, and the clogging of the ball in the game ball passage Although there is a problem of causing a malfunction such as a short circuit of an electrical component, according to the configuration of the above means E4, the separation portion of the breaking screw after being separated is retained by the protective member, so that the separation portion becomes dusty. In addition, it is possible to save the trouble of processing, and since it does not enter through the gap in the gaming machine, it is possible to prevent a problem from occurring.

Further, the gaming machine according to the present invention is a gaming machine of means E4 as means E5.
After the protective member has a wall that covers the head of the breaking screw at least from the side operated by the operation instrument, and has an operation hole through which the operation instrument can be inserted without allowing the separation part to pass through, and after separation The separation portion is held at a position between the head main body of the breaking screw and the operation hole.

According to the configuration of the means E5, the separated portion after being separated is covered with the wall of the protective member, so that it is reliably held and prevented from falling off.
In addition, as described above, the head body in the head of the breaking screw after the separation part has been separated cannot be loosened by turning it backwards depending on the operation tool. If this is the case, the connected state may be illegally released by a forcible method, for example, by joining a rod-shaped fraudulent tool to the head body from the outside with an adhesive and rotating it backward. However, according to the configuration of the means E5, the separation part after separation is held at a position between the head main body and the operation hole by the protective member, so that the separation part becomes an obstacle from the outside. An unauthorized tool cannot be delivered to the head body, and therefore it is possible to more reliably prevent an unauthorized connection from being released.

A gaming machine according to the present invention is a gaming machine of any one of means E1 to E5 as means E6.
The protective member has a first housing portion for housing the head body of the breaking screw in a state before breaking, and a second housing portion for housing the separation portion, and the head body is axial in the first housing portion. In addition, the margin that allows free movement in the radial direction is equal to or less than the allowance in which the separation portion can move in the axial direction and radial direction in the second accommodating portion.

  According to the configuration of the means E6, for example, when the breaking screw and the protection member are moved in the axial direction or the radial direction by an external force, the external force is evenly transmitted to the head body and the separating portion, or the head An external force is transmitted only to the main part. In other words, the external force is received at least by the head main body, and only the separating portion does not receive the external force. Therefore, it is possible to effectively prevent the separating portion from being erroneously broken by this external force.

Further, the gaming machine according to the present invention is a gaming machine of means E6 as means E7.
The diameter of the 1st accommodating part in the said protection member is larger than the diameter of the 2nd accommodating part, It is characterized by the above-mentioned.

  According to the configuration of the means E7, the protective member expands in a stepped shape from the first housing portion to the second housing portion, so that the shape becomes easier to mold.

A gaming machine according to the present invention is a gaming machine according to any one of the means E5 to E7 as the means E8.
The separation part of the breaking screw in the state before the breaking is held in a posture fitted to the operation hole of the protective member.

  According to the configuration of the means E8, the engaging portion of the breaking screw is held in a posture not drawn inward from the operation hole of the protective member, and therefore the operating instrument is engaged with the engaging portion from the outside. It is easy to make it easy to fasten.

A gaming machine according to the present invention is a gaming machine according to any one of means E1 to E7 as means E9.
The head body of the breaking screw has a flange extending radially;
At the end in the fastening direction side of the breaking screw in the protective member, a latching portion is formed that extends inward from the outer peripheral side of the breaking screw to the center side and latches on the flange,
The gap between the shaft-side end of the breaker screw head body and the flange portion is larger than the thickness of the latching portion of the protective member.

  According to the configuration of the means E9, the latching portion of the protective member is latched with a slight margin between the shaft side end and the flange portion of the head body of the fracture screw. Even in a state where the protective screw is fastened, the protective member can be freely rotated with respect to the breaking screw, that is, kept in a state where it can freely idle (idle), so that the breaking screw is reliably rotated from the outside Can be prevented. If there is no allowance as described above, when the protection member is rotated, the break screw is rotated together with the break screw without idling. As a result, the break screw is rotated by rotating the protection member from the outside. Although it may be possible to loosen, it is possible to make it difficult to loosen the breaking screw from the outside by providing a structure such that the protective member can idle by providing a margin as in the means E9. .

In addition, the gaming machine according to the present invention is a gaming machine of any one of means E5 to E9 as means E10.
The protective member is characterized in that the separation portion after separation in the breaking screw is held in a posture that does not protrude from the operation hole.

  If the separated part after separation protrudes from the operation hole, if the projecting part is gripped with pliers or the like and rotated while being strongly pulled, the protective member may rotate to loosen the breaking screw. According to such a method, for example, even if the protective member is surrounded by some other structure (such as a peripheral wall of the sealing portion) and it is difficult to grip and rotate the protective member, the breaking screw is separated. It becomes possible to reversely rotate the breaking screw through the protective member from the portion. At this time, even if the protective member is configured to freely rotate with respect to the breaking screw as in the means E9, if the protective member is rotated while being gripped and pulled as described above, The breaking screw is also loosened by being rotated together with the protective member while being hooked on the hooking portion of the protective member at the collar portion. On the other hand, if the separating portion is held in a posture that does not protrude from the operation hole as in the above-described means E10, it is difficult to grip the separating portion. Can be difficult.

In addition, the gaming machine according to the present invention is a gaming machine according to any one of the means E1 to E10 as the means E11.
The protection member is configured to cover at least a part of the breaking screw except for an engaging portion by combining a plurality of divided bodies.

  According to the configuration of the means E11, the protective member can be attached to the breaking screw more easily. For example, in the case of a protective member that is inherently integrally configured without being divided into a plurality of divided bodies in this way, it takes some effort to make it possible to accommodate the breaking screw without dropping off. . Specifically, for example, in the case of a cylindrical protective member, the breaking screw should not be dropped by a method such as deforming the end portion inside after loading the breaking screw inside or covering with a member. Need to be accommodated. On the other hand, in the configuration of the means E11, a combination of a plurality of divided bodies allows the breaking screw to be accommodated inside without dropping off, so the above-described method such as deformation or lid is used. And can be easily and reliably attached to the breaking screw.

Further, the gaming machine according to the present invention is a gaming machine of means E11 as means E12.
The plurality of divided bodies are mounted so as to cover the breaking screw from the side.

According to the configuration of the means E12, it is possible to configure a protective member having an internal shape that closely follows the shape of the breaking screw, thereby making it possible to protect the breaking screw more reliably. In the case of a break screw, a small-diameter break portion (thin diameter portion) is formed in the middle part of the head, and has a undulation shape unlike ordinary screws. For example, in the case of a cylindrical housing member The internal shape that follows the undulating shape of such a breaking screw makes it difficult to insert the breaking screw inside, so that a sufficient space for inserting the breaking screw is secured. It is necessary to have an internal shape that extends without undulations. On the other hand, according to the protective member of the means E12, by having an internal shape that closely follows the shape of the breaking screw, the breaking screw can be accommodated without forming a gap as much as possible. Since no allowance for allowing a sufficient movement of the breaking screw is formed in the inside of the housing, erroneous breakage can be prevented more effectively.
In addition, for example, when the end of the housing member is deformed inward after the breaking screw is loaded inside as described above, the breaking screw is erroneously broken by the force applied for the deformation of the housing member. On the other hand, if it is configured to cover the breaking screw from the side like the protective member of the means E12, a force that may cause an erroneous breaking is applied to the breaking screw. A protective member can be mounted without any.

In addition, the gaming machine according to the present invention is a gaming machine of means E11 or means E12 as means E13.
The plurality of divided bodies are configured to be openable and closable.

  According to the configuration of the means E13, the protective member can be attached to the breaking screw more easily and reliably. For example, a plurality of divided bodies constituting the protective member may be separated from each other, and the broken screws may be accommodated inside by combining the divided bodies. If the divided parts to be combined are asymmetric, it is necessary to prepare and handle the corresponding divided parts as a set. On the other hand, if the protective member of the means E13 is used, In addition, it is not necessary to pay attention to alignment and combinations of divided bodies.

A gaming machine according to the present invention is a gaming machine of means E13 as means E14.
The plurality of divided bodies are integrally formed so as to be continuous through a flexible portion.

  According to the configuration of the means E14, a protective member that can be easily molded with a simple configuration can be obtained.

A gaming machine according to the present invention is a gaming machine of any one of means E11 to E14 as means E15.
The plurality of divided bodies are configured to be engaged and fixed in a closed state by an engagement mechanism.

  According to the configuration of the means E15, it can be easily attached to the breaking screw without requiring another fixing means or tool, and can be fixed in a closed state without applying a large force. It is possible to prevent the screw from being broken more effectively.

In addition, the gaming machine according to the present invention is a gaming machine according to any one of the means E11 to E15 as the means E16.
The breaking screw fitted with the protective member is screwed in a state surrounded by a peripheral wall portion.

  According to the configuration of the means E16, it is possible to make it difficult to remove the screwed breaking screw together with the protective member by illegally rotating it from the outside.

Further, the gaming machine according to the present invention is a gaming machine of means E16 as means E17.
A gap is not substantially formed between the protective member and the peripheral wall portion.

  According to the configuration of the means E17, it is possible to make it more difficult to remove the screwed breakage screw together with the protection member from the outside by illegally rotating it from the outside.

Further, the gaming machine according to the present invention is a gaming machine of means E17 as means E18.
The breaking screw equipped with the protective member is screwed in a state surrounded by another peripheral wall portion in addition to the peripheral wall portion, that is, in a state surrounded by a double peripheral wall portion. To do.

  According to the configuration of the means E18, it is possible to make it more difficult to remove the screwed breaking screw together with the protective member by illegally rotating it from the outside. In other words, since the break screw has a structure that is triple-wrapped when the protective member is combined, it is possible that the illegal act from the outside is more difficult.

Further, the gaming machine according to the present invention is a gaming machine of means E17 or means E18 as means E19.
The peripheral wall portion has a depth larger than that of the protective member in the axial direction (axial direction of the breaking screw).

  According to the configuration of the means E19, it is possible to make it more difficult to remove the screwed broken screw together with the protective member by illegally rotating it from the outside. Further, the breaking screw equipped with the protective member can be screwed in such a manner that the inside of the peripheral wall portion is moved inward along the axial direction, thereby making the peripheral wall portion function as a guide and facilitating the screwing operation. be able to.
