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.

Examples of the gaming machine using the above breaking screw include those described in the following documents.
JP 2007-252802 A

  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 to this, the rupture portion may break and become unusable as a screw before being used for fastening (hereinafter, this situation is also referred to as “false break”).

  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. In addition, since it becomes necessary to handle the case separately after that, the work becomes cumbersome.

  The present invention has been devised in view of such a problem, and in a gaming machine using a broken screw, it is possible to effectively prevent erroneous breakage of the broken screw and to easily perform a fastening operation. An object is to provide a gaming machine that can be used.

In order to achieve the above object, the gaming machine according to the present invention includes means 1 as follows:
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 in which two or more components are connected by a screw (hereinafter referred to as a breaking screw),
The breaking screw is formed by bending a plate-like member, and includes a protective member that covers at least a part of the separating portion in a state before breaking, except for the engaging portion. .

  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 above means 1, even if a certain external force is applied before the fastening operation, 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.

The gaming machine according to the present invention is a gaming machine of means 1 as means 2,
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 2, the broken portion of the breaking screw is more effectively prevented by covering the thin portion, which is the portion where the breaking screw breaks, with the protective member.

Further, the gaming machine according to the present invention is a gaming machine of means 1 or means 2 as means 3,
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 3, the separation portion is covered with the protection member in its entirety other than the engagement portion, so that it can be more reliably protected from external force, thereby preventing the broken screw from being broken more effectively.

A gaming machine according to the present invention is a gaming machine according to any one of the means 1 to 3, as the means 4.
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 4, the separation portion is separated by holding the separation portion of the broken screw after separation by a protective member. 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 4 as means 5,
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 5, since the separated portion after being separated is covered with the wall of the protective member, 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 5, 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.

In addition, the gaming machine according to the present invention is a gaming machine according to any one of the means 1 to 5, as the means 6.
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 6 described above, for example, when the breaking screw and the protection member loosely move in the axial direction or the radial direction due to 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 body, so that 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 6 as means 7,
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 structure of the said means 7, since a protective member is diameter-expanded from a 1st accommodating part to a 2nd accommodating part, it becomes a shape which is easier to shape | mold.

A gaming machine according to the present invention is a gaming machine according to any one of the means 5 to 7, as the means 8.
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 8, 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 the means 1 to 7, as the means 9.
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 9, the latching portion of the protection member is latched between the shaft-side end of the head portion of the breaking screw and the flange portion with a slight margin. 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 it is ensured that the breaking screw is reversely 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 margin such as the means 9 so that the protective member can idle. .

A gaming machine according to the present invention is a gaming machine according to any one of the means 5 to 9, as the means 10.
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 idle with respect to the breaking screw as in the means 9, if the protective member is rotated while being gripped and pulled as described above, The broken screw is also rotated and loosened together with the protective member while being hooked on the hook 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 10, it is difficult to grip the separating portion, and therefore the protective member is rotated from the outside in reverse to loosen the breaking screw. Can be difficult.

  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 inner frame 12 with a fastener such as a screw. On the front side of the lower plate unit 13, there are provided a lower plate 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 (positions on the left and right upper ends of the inner frame 12). 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).

  Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are molded from flame-retardant ABS resin. For this reason, this part is hard to burn.

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. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  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). is 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 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, a game ball that is launched in accordance with the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail, and then guided to a predetermined game area through the ball guide path 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. In the state of FIG. 4, the shutter is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like, and the discharge port 67 is closed so that the game ball does not spill from the discharge port 67.

  Further, when the front frame 14 is closed, the shutter is pushed open by a ball passage rod 69 (see FIG. 4) provided on the back surface of the front frame 14 to be in a substantially horizontal state and discharged toward the discharge port 67. The played game balls are discharged to the upper plate 19 through the ball passageway 69 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game ball in the payout passage or the like spills out of the pachinko machine 10 when the front frame 14 is opened.

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 one. 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.

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 receiving 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 of the inner periphery by enlarging the inner periphery.

  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 body posture and is rotatably held 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 a certain external force is applied before performing, erroneous breakage of the break screw 651 is effectively prevented.

  As shown in FIG. 26A, the breaking screw 651 fitted with the accommodating member 621 as described above is inserted 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 part 450 and the second mounting base sealing part 432 which are the target parts to be screwed.

  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 work such as handling a separate item.

  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. .

  Since the separation portion 654 after separation is in a state where the flange portion 657 cannot be pulled out to the outside by engaging with the operation hole 622 as described above, the separation portion 654 continues to be restrained in the housing member 621 and remains at the head of the breaking screw 651. 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 part 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 part 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. The separation member 654, which is a portion that can be broken and separated when rotated, connects the two constituent members, that is, the first control board box 201A and the connection mounting base member 430 by the break screw 651 formed on the head 652. In the above configuration, since the breaking screw 651 includes the housing member 621 as a protective member that covers the portion of the separating portion 654 other than the screw hole in the state before breaking, any external force is required before performing the fastening operation. Even when receiving, the separation portion 654 is protected from this external force by being covered with the accommodating member 621, and thereby the breaking screw 6 1 false break 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 thin-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.

  In addition, since the housing member 621 is configured to surround the entire separation portion 654 of the breaking screw 651 except for the screw holes, the entire portion of the separation portion 654 other than the screw holes 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 also has 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 accommodation cavity 623 is larger than a distance d1 between the head body 655 and the head body accommodation 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 is loosened. 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.

  Hereafter, an example of the process of producing the fracture | rupture screw which has the above collar parts with a header (forging machine) is demonstrated one by one simply.

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 from the shaft insertion hole 660 is inclined inward (ie, the right-angled corners on the front side at both ends of the metal plate are inclined obliquely inwardly so as to be retracted inwardly). 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 surfaces 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 surfaces 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 on the side 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) In any of the first to seventh 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.

(8) 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.

Above all,
A connecting portion between the first case and the second case constituting the main control board box;
・ A connecting part between the delivery board box and the connecting mounting base member,
A connecting portion between the first case and the second case constituting the dispensing board box;
・ Connecting part of mounting base member and ball assembly plate,
・ Mounting part of the payout mechanism part,
・ Mounting detection sensor of the winning device corresponding to the starting opening, winning detection sensor of the winning device corresponding to the large winning opening, and mounting portion of the relay board that relays the solenoid and the main control board,
Etc., all of which are prone to fraud, so 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.

(9) In the first embodiment, the pachinko machine 10 is exemplified. However, 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 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, valuable objects include coins, medals and the like as representative examples.

  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.
