  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. 4, a front frame set opening detection switch 90 that detects that the front frame 14 is opened with respect to the inner frame 12 is provided on the upper side of the inner frame 12. When the front frame 14 is opened, it is output from the front frame set open detection switch 90 to the computer for the hall (in the pachinko parlor). Further, when the front frame 14 is closed, the metal reinforcing plate of the front frame 14 comes into contact with the pair of metal fittings of the inner frame 12, and the grounding of the front frame 14 is ensured.

Here, the front frame 14 described above will be described in more detail with reference to FIGS. 1 to 4.

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. The separation part 654 and the head main body 655 are basically cylindrical, and the head main body 655 has a slightly larger diameter than the separation part 654. The diameter gradually decreases in a taper 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 658 shown in FIGS. 26 and 27 is fitted to the head 652 of the breaking screw 651. FIG. 26 is a perspective view of the housing member 658, and FIG. 27 is a development view of the housing member 658. The housing member 658 is prepared by forming a single metal plate into a substantially rectangular shape (or strip shape) that extends slightly longer as shown in FIG. 27 to form predetermined holes, cuts, etc. As shown in FIG. 26, the rectangular parallelepiped is opened so that the front surface and the back surface are open, and the top surface, the 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 that can be obtained.

  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. 26, as shown in FIG. 26, 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. 26, 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-introducing notches 661 are inclined edges that incline the front side edge of the portion that becomes the bottom plate 658B at both ends of the metal plate in the unfolded state shown in FIG. 27, and both edges (both short edges) of the metal plate. ) 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. 27, and inside the cuts 663R and 663L. It is formed by bending so as to cause the formed rectangular piece. Here, of the two elastic pieces 662R and 662L, one elastic piece 662L (on the left side in FIG. 26) has a larger amount of bending than the other elastic piece 662R (on the right side in FIG. 26). That is, in FIG. 26, it is formed so as to be inclined upward as compared with the other elastic piece 662R.

  In the housing member 658, the head portion 652 of the breaking screw 651 is inserted and housed from the front portion, and at this time, the shaft portion 653 of the breaking screw 651 is guided to the shaft introduction notch 661 and is inserted into the shaft insertion hole. 660 is inserted. Thereby, as shown in FIG. 28A, the housing member 658 is fitted to the head 652 of the breaking screw 651.

  At this time, as described above, since the diameter of the operation hole 659 in the housing member 658 is smaller than the outer diameter of the flange portion 657 of the breaking screw 651, the flange portion 657 is engaged with the periphery of the operation hole 659 and the breaking screw 651 is engaged. However, the shaft insertion hole 660 of the bottom plate 658B cannot be inserted through the head main body 655 of the head 652 of the breaking screw 651. The head body 655 is engaged with the peripheral edge of the shaft insertion hole 660 so that the head 652 of the breaking screw 651 cannot come out of the shaft insertion hole 660. Therefore, the head 652 of the breaking screw 651 is accommodated. It is securely held in the state of being accommodated in the member 658. 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 659, and the tip end surface where the screw hole (not shown) is formed is exposed from the operation hole 659. It is held in a posture and is rotatably held in the housing member 658.

  At this time, both elastic pieces 662R and 662L of the housing member 658 abut against the tapered portion 654T of the separating portion 654 of the breaking screw 651 and urge the head 652 of the breaking screw 651 to push up from below.

  As shown in FIG. 28A, the breaking screw 651 fitted with the housing member 658 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 659. Is inserted and rotated to be screwed into the first mounting base sealing portion 450 and the second mounting base sealing portion 432.

  At this time, since the head 652 of the breaking screw 651 is rotatably held in the housing member 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, it is difficult to grip the housing member 658 from the outside in a state where the breaking screw 651 is almost housed in the second mounting base sealing portion 432, but the housing member 658 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 658 also functions as a support (support) for the screw 651 at the time of screwing operation. can do.

  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 rotating at a higher torque, the head 652 of the breaking screw 651 breaks at the small diameter portion 656 and the separating portion 654 is separated from the head body 655 as shown in FIG. .

  The separation portion 654 after being separated is still in a state where the flange portion 657 is engaged with the peripheral edge of the operation hole 659 as described above, and thus cannot be pulled out from the operation hole 659, but the front portion of the housing member 658 and Since the back surface portion is open, it is considered that after the separation from the head main body 655, the housing member 658 is not restrained from being pulled out from the front surface portion and the back surface portion. However, since the separating portion 654 of the breaking screw 651 is biased upward by the elastic pieces 662R and 662L of the housing member 658 as described above, when separated from the head body 655, as shown in FIG. Further, the cylindrical portion 654P is lifted upward while holding the posture fitted in the operation hole 659, and held so as to be pressed against the upper surface portion (ceiling portion) in the housing member 658. Therefore, the housing member 658 is retained. In this way, the head portion 655 and the operation hole 659 are continuously held at the position.

  Further, at this time, as described above, one of the elastic pieces 662R and 662L (on the left in the drawing) 662L is inclined more than the other (on the right in the drawing) elastic piece 662R. Therefore, both elastic pieces 662R and 662L apply unequal urging forces to the separating portion 654 of the breaking screw 651. Therefore, the separating portion 654 of the breaking screw 651 is separated by the elastic piece 662L. It is lifted further upward and held in a posture inclined to one side as shown in FIG.

  The separation part 654 is prevented from falling off by being held in the housing member 658 as described above. 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 659 to grip the head main body 655, or a rod-like fraudulent tool is inserted to join the tip of the head main body 655 with an adhesive. Even if the head main body 655 is forced to reversely rotate, the separation portion 654 after the separation is positioned in the housing member 658 between the head main body 655 and the operation hole 659 by the elastic pieces 662R and 662L. By being held, the separation part 654 becomes an obstacle, and pliers and unauthorized tools cannot be delivered from the outside to the head body. Therefore, it is difficult to illegally release the connection state by the breaking screw 651. It has become.

  At this time, in the state where the housing member 658 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 658 by inserting fingers or instruments from the outside of the mounting base sealing portion 432. If it is possible to turn the housing member 658, turning the housing member 658 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 covered from the side by the side plates 658R and 658L which are side portions of the housing member 658, the separation portion 654 is more reliably prevented from falling off. Further, since the head main body 655 is also covered from the side, it is more difficult for an unauthorized operation from the outside to reach.

  Further, since the separated portion 654 after being separated is held in an inclined posture with respect to the head main body 655 by the non-uniform urging forces of both elastic pieces 662R, 662L, even if the separating portion 654 is rotated. Since the directions of the rotation axes do not match, it is difficult to rotate the head body 655. At this time, if, for example, the inclination of the separation unit 654 can be corrected from the outside and the direction of the rotation axis can be aligned with the head body 655, the separation unit 654 is attached to the head body 655 with a driver or the like. If it is rotated counterclockwise while pressing strongly, it is considered that frictional force acts between the fractured surfaces and the head body 655 may rotate together with the separating portion 654, but both elastic pieces 662R as described above. , 662L with an uneven urging force applied, the inclination of the separating portion 654 is corrected against the urging force, that is, the separating portion 654 is rotated together with the head body 655 while maintaining a good balance. It is difficult to do.

  Further, since the separation portion 654 after being separated is held in a posture fitted to the operation hole 659, the operation hole 659 is held in a closed state, so that the separation portion 654 functions reliably as an obstacle. It is possible to effectively prevent an unauthorized tool from approaching the head body 655 from the operation hole 659.

(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-described configuration, elastic pieces 662R and 662L are provided as urging means for holding the separated separating portion 654 in a predetermined position of the gaming machine, that is, in the housing member 658 by the urging force. 1 Even when the separation portion 654 is separated when the control board box 201A and the connection mounting base member 430 are coupled, the separation portion 654 is not accommodated. It can to hold within member 658, thus not become dust, together has become troublesome to handle also unnecessary, since nor enter from a gap of the gaming machine, which is less likely to occur even failure.

In addition, it has a wall that covers at least the head 652 of the breaking screw 651 from the side operated by the driver, that is, a top plate 658T, and is accommodated as a restricting means having an operation hole 659 through which the driver cannot be passed through the separation portion 654 The elastic pieces 662R and 662L, which are members 658 and are urging means, separate the separated portion 654 between the head main body 655 in the head 652 of the breaking screw 651 and the operation hole 659 in the housing member 658. Since the separation portion 654 after being separated is in a state of being covered by the housing member 658 and also receiving the urging force by the elastic pieces 662R and 662L, the separation portion 654 is more securely held and the drop-off preventing effect is improved. ing.
Further, as described above, the head main body 655 which is a remaining portion of the head 652 of the breaking screw 651 after the separation portion 654 has been separated cannot be loosened by rotating it backwards depending on the driver. Assuming that the main body 655 is open to the outside, the connected state may be illegally released by a forcible method such as joining a head-shaped main body 655 to the head main body 655 with an adhesive from the outside and rotating it backward. possible. However, in the pachinko machine 10 according to the present embodiment, the separation portion 654 after separation is held at a position between the head body 655 and the operation hole 659 by the elastic pieces 662R and 662L. 654 becomes an obstacle and the unauthorized tool cannot reach the head main body 655 from the outside. Therefore, the connection state is more reliably prevented from being illegally released.

Further, since the housing member 658 has side plates 658R and 658L as side portions covering the head 652 of the breaking screw 651 from the side, the separated portion 654 after being separated is also covered from the side by the side plates 658R and 658L. Therefore, it is held more securely and the drop-off preventing effect is further improved.
Further, the head main body 655 is also covered from the side, so that it is more difficult for an unauthorized operation from the outside to reach.

  Further, as the biasing means, elastic pieces 662R and 662L that extend inward from the side plates 658R and 658L and apply a biasing force to the separation portion 654 of the breaking screw 651 are provided, so that the separation portion 654 after separation is provided. The elastic pieces 662R and 662L can be easily and reliably held at a position between the head body 655 and the operation hole 659, and a biasing means can be easily provided by a simple structure. Yes. Here, for example, the urging means can be provided separately from the housing member 658, but in the pachinko machine 10 of the present embodiment, the elastic pieces 662R, 662L are extended from the side plates 658R, 658L inward. Since the biasing means is provided, the biasing means can be easily provided integrally with the housing member 658.

  Further, side plates 658R and 658L are respectively provided at positions that cover the head 652 of the breaking screw 651 from both sides, and elastic plates 662R and 662L are respectively provided on the side plates 658R and 658L, and both elastic pieces 662R and 662L are provided. Since unequal urging forces are applied to the separation portion 654 of the breaking screw 651, the separation portion 654 after separation is held in an inclined posture with respect to the head body 655, and thus the separation portion 654 is rotated. However, since it is difficult to rotate the head body 655 with this, it is more difficult to rotate the head body 655 from the outside. Here, if the two elastic pieces are configured to be symmetrical with each other and an equal urging force is applied to the separation portion 654 of the breaking screw 651, the separation portion 654 after separation is also intact. It will be held in a balanced position. In this case, for example, if a driver is inserted through the operation hole and the separation portion 654 is rotated counterclockwise while being strongly pressed against the head body 655, a frictional force acts between the fracture surfaces, and the head body 655 together with the separation portion 654. May also rotate.

  Further, since the elastic pieces 662R and 662L hold the separated portion 654 after being separated in a posture fitted to the operation hole 659, the operation hole 659 is held closed by the separated portion 654 after being separated. Therefore, the separation unit 654 can be reliably functioned as an obstacle, and an unauthorized tool can be effectively prevented from approaching the head body 655 from the operation hole 659.

  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.

  In addition, since the notch 620 is formed in the thread 619 of the breaking screw 651, the resin, which is a constituent material of the first mounting base sealing portion 450 and the second mounting base sealing portion 432, which are target parts to be screwed, is notched. The breaking screw 651 can be screwed in while making it bite into 620. Therefore, the loosening prevention effect of the breaking screw 651 is better.

(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) FIG. 29 is a developed view showing another example of a housing member as a restricting means, and FIG. 30 is a diagram showing how the separating member of the breaking screw is separated by fitting the housing member to the head of the breaking screw. It is a schematic cross section which shows the situation. 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, like the housing member 658 in the first embodiment. In this case, a top plate 671T, a side plate 671R, and a 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. . 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 first embodiment. Unlike the bottom plate 658B of the housing member 658 in the first 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 center 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 present embodiment, as shown in FIG. 30, when the separating portion 654 of the breaking screw 651 is separated, the separating portion 654 is lifted from one side by the elastic piece 673R and is separated from the top plate 671T. Is held between the two. At this time, since the urging force is applied only from one side by the elastic piece 673R, the separating portion 654 is held in an inclined posture as shown in FIG.

  In the case of the housing member 671 in this embodiment, not only the front and back surfaces but also one side surface (the left side surface in FIG. 30) is open, so that the work of inserting and housing the head portion 652 of the fracture screw 651 is likely. There is also an advantage that it becomes easy, but on the other hand, it is easy to open the upper surface part by opening the part having the operation hole 672 (top plate 671T) in the direction opposite to the bending direction, so that it can be accommodated. There is also a tendency that fraud is easily made to the inside of the member 671. For this reason, from the viewpoint of preventing fraud, it is desirable that both side surfaces be closed by both side plates 658R and 658L, similar to the housing member 658 in the first embodiment.

(2) FIG. 31 is a developed 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 first 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 according to the first embodiment has the same configuration as that of the first embodiment except that the housing member 658 according to the first embodiment has a substantially rectangular shape that extends slightly in the expanded state. The housing member 675 according to the present embodiment has a substantially cross shape as a whole when the front plate 675F and the back plate 675W are added thereto.

In the case of the accommodation member 675 in this embodiment, the upper surface, the lower surface, 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 further securely held and prevented from falling off. The 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 difficult to be detached from the housing member 675, a large amount of the housing member 675 attached to the breaking screw 651 can be flowed 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.

(3) FIG. 32 is a development view showing still another example of a housing member as a restricting means, and FIG. 33 is a diagram showing a separation portion of the breaking screw by fitting the housing member to the head of the breaking screw. It is a schematic cross section which shows the condition made to do. The housing member 676 shown in the figure has the same configuration as the housing member 658 in the first embodiment except for the configuration of the elastic pieces 677R and 677L on both sides. In the first embodiment, by forming one elastic piece 662L of the elastic pieces 662R, 662L of the housing member 658 so as to be inclined upward with respect to the other elastic piece 662R, both elastic pieces 662R, 662L is configured to apply unequal urging forces to the separating portion 654 of the breaking screw 651 so as to hold the separating portion 654 in a slanted posture, but in the present embodiment, both elastic pieces Although the inclinations of 677R and 677L are substantially equal, by forming the notches 678R and 678L on both sides in different shapes, the length of one elastic piece 677R (the right side in the figure) is relatively long, The elastic piece 677L (on the left side in the figure) is formed relatively short, which causes the urging forces of the two elastic pieces 677R and 677L to become uneven and separate. Separating portion 654 of the after is adapted to be held in the posture inclined to one.

(4) FIG. 34 is a developed view showing still another example of a housing member as a restricting means, and FIG. 35 is a diagram showing how the housing member is fitted to the head of the breaking screw to separate the separating portion of the breaking screw. It is a schematic cross section which shows the condition made to do. The housing member 679 shown in the figure has the same configuration as the housing member 658 in the first embodiment except for the configuration of the elastic pieces 680R and 680L on both sides. In the elastic pieces 680R and 680L in the present embodiment, engagement concave portions 681R and 681L having curved shapes (arc shapes) corresponding to the shapes of the tapered portions 654T of the separating portion 654 of the breaking screw 651 are formed at the tip edges, respectively. Has been. As a result, the tapered portion 654T of the separating portion 654 of the breaking screw 651 is held so as to engage with the engaging recesses 681R and 681L, so that the separating portion 654 is held more stably and surely at an appropriate position. Is done. Further, of the two engagement recesses 681R and 681L, one (right side in the drawing) engagement recess 681R has a relatively small diameter, and the other (left side in the drawing) engagement recess 681L has a relatively large diameter. As a result, the tapered portion 654T of the separating portion 654 of the breaking screw 651 is relatively shallow in one (right side in the drawing) engagement recess 681R and the other (left side in the drawing) is engaged. The recessed portion 681L is relatively deeply engaged. Therefore, the urging forces of both elastic pieces 680R and 680L are applied to the separating portion 654 in an uneven manner, so that the separating portion 654 after being separated becomes one side. It is designed to be held in an inclined position.

(5) FIG. 36 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 first embodiment except for the configuration of the bottom plate 682B. The bottom plate 682B in the present embodiment is divided and configured in the same manner as the bottom plate 658B of the housing member 658 in the first 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 divided body of the bottom plate 682B is expanded to both sides larger than in the case of the first embodiment. The shaft portion 653 is configured to be more difficult to detach.

Further, in the present 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, the shaft portion 653 of the breaking screw 651 is pushed into the inner back portion of the shaft introduction notch 684. Both oblique sides 682D and 682D gradually expand to both sides, 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 is accommodated therein. Then, both the 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 securely inserted into the shaft insertion hole 683. And thus it held in. 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) FIG. 37 is a perspective view showing another example of a housing member as a restricting means, and FIG. 38 is a schematic cross-sectional view showing a situation in which this housing member is fitted to the head of a fracture screw. 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 the operation hole 659 of the housing member 658 in the first 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. As shown in FIG. 38, the elastic pieces 669R and 669L are integrally formed on the peripheral wall portion of the housing member 664 so as to extend inward. On the fixed end side of each elastic piece 669R, 669L, as shown in FIG. 37, a cut 670 is formed in the peripheral wall portion along the axial direction of the housing member 664 from both sides of each elastic piece 669R, 669L. Accordingly, each elastic piece 669R, 669L can be deformed integrally with the portion between the notches 670 (that is, as a whole, it forms a bowl-shaped elastic piece together with the portion between the notches 670). When the head 652 of the breaking screw 651 is accommodated in the accommodating member 664, the portion between the notches 670 is deformed so as to be pulled out to the outside of the accommodating member 664, thereby extending inwardly. The protruding elastic pieces 669R and 669L can be retracted from the inner peripheral surface of the housing member 664. As in the case of the two elastic pieces 662R and 662L in the first embodiment, one elastic piece 669L (on the left side in FIG. 38) of the two elastic pieces 669R and 669L is the other (on the right side in FIG. 38). The elastic piece 669R is inclined upward.

  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 accommodating member 664 is fitted to the head 652 of the breaking screw 651 as shown in FIG.

The housing member 664 shown in FIGS. 37 and 38, including the elastic pieces 669R and 669L, can basically function substantially the same as the housing member 658 in the first embodiment. Is formed in a peripheral wall shape that surrounds the periphery of the head portion 652 of the breaking screw 651, so that the separated portion 654 after being separated is held so as to be surrounded by the peripheral wall side surface portion. Therefore, it is more reliably held and the drop-off preventing effect is further improved.
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.

  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. .

(7) In the first embodiment, the housing member 658 serving as the restricting means is fitted to the head 652 of the breaking screw 651. However, such a restricting means may not be provided. .

  FIG. 39 is a perspective view showing an example of a configuration in which the regulating means is omitted. In the example shown in the figure, a rectangular parallelepiped first sealing portion 633 and a second sealing portion 634 project from the first component member 631 and the second component member 632 that are connected to each other, and as an urging means, A leaf spring member 635 having a shape in which the cross section is substantially U-shaped and both end portions are bent outward to form locking pieces 635L and 635R is detachable from the peripheral wall of the first sealing portion 633 It is supposed to be fitted to the. Two notches 633L and 633R extending from the end edge at right angles from the end edge are formed on the peripheral wall of the first sealing portion 633, and the distance between the notches 633L and 633R is the both locking pieces of the plate spring member 635. It is slightly smaller than the interval between 635L and 635R, both ends of the leaf spring member 635 are inserted into the notches 633L and 633R, and both locking pieces 635L and 635R are placed outside the peripheral wall of the first sealing portion 633. The leaf spring member 635 is fitted into the first sealing portion 633 so as to bulge into the first sealing portion 633.

  When the breaking screw 651 is screwed from the first sealing portion 633 to connect the first sealing portion 633 and the second sealing portion 634, and the separation portion 654 of the breaking screw 651 is separated from the head body 655. The separating portion 654 is held so as to be pressed against the inner surface of the peripheral wall of the first sealing portion 633 by the urging force from the leaf spring member 635. Therefore, even with this configuration, the separated separation portion 654 does not become garbage, and it is possible to save the trouble of processing, and since it does not enter through a gap in the gaming machine, it is possible to prevent a problem from occurring.

  In the case of the configuration shown in FIG. 39, the separated portion 654 after being separated is not covered by the restricting means such as the housing member 658 in the first embodiment, but from the leaf spring member 635 that is an urging means. Since it becomes the structure hold | maintained in the 1st sealing part 633 only by urging | biasing force, a control means is abbreviate | omitted and it is the structure simple.

  In this case, the first sealing portion 633 is also in a state in which the separation portion 654 of the separated breaking screw 651 is pressed against the inner surface of the peripheral wall of the first sealing portion 633 by the urging force from the leaf spring member 635 even after shipment. It may be possible to keep the separation part 654 from falling off, and it is considered that no problem will occur. Alternatively, after the separation part 654 of the breaking screw 651 is separated, The separation unit 654 may be removed from the first sealing unit 633 and removed from the gaming machine at any stage of the above, for example, at the stage before the manufacturing process of the gaming machine is completed and before shipping. According to this, the separation portion 654 is first sealed by some accidental factor such as contact from the outside or mechanical shock at any time, for example, during transfer or during installation work in the hall or after installation. It is possible to reliably prevent such a situation that the detachment from the inside of the portion 633, scattering inside and outside the gaming machine to become garbage, or entering the gap in the gaming machine to cause a malfunction.

  Further, in this case, since the leaf spring member 635 as the urging means is detachably provided, the leaf spring member 635 may be removed at the time of removing the separating portion 654 of the breaking screw 651 or after that. According to this, the leaf spring member 635 can be reused.

(8) FIG. 40 is a perspective view showing an example of a configuration in which a holding mechanism is provided in the urging means. In the example shown in the drawing, as an urging means, an elastic piece 630E having a C-shape in plan view is integrally formed with one piece of a base portion 640S formed into a clip shape and folded into a U-shape. A holding member 640 having a protruding configuration is detachably fitted to the peripheral wall of the first rectangular parallelepiped first sealing portion 641. The elastic piece 630E of the holding member 640 has an inner diameter that is slightly smaller than the diameter of the columnar portion 654P of the separation portion 654 of the breaking screw 651, and can be fitted to the circumferential surface of the columnar portion 654P while slightly expanding. Thus, a gripping mechanism is configured to hold the separating portion 654 of the breaking screw 651 so as to be elastically gripped.

  While the breaking screw 651 is screwed from the first sealing portion 641 or after the breaking screw 651 is screwed, the elastic piece 630E of the holding member 640 is fitted into the head 652 of the breaking screw 651 from above. Even after the separation part 654 of the breaking screw 651 is separated from the head body 655 by fitting the holding member 640 to the peripheral wall of the first sealing part 641, the separation part 654 is an elastic piece of the holding member 640. Since the flange portion 657 of the separation portion 654 is locked to the elastic piece 630E at this time, the separation portion 654 is reliably prevented from being detached.

  In the case of the configuration shown in FIG. 40, as in the case of the configuration shown in FIG. 39, the separation portion 654 is placed in the first sealing portion 641 at an arbitrary stage after the separation portion 654 of the breaking screw 651 is separated. It is also possible to remove the holding member 640 at the time when the separating portion 654 of the breaking screw 651 is removed or after that, but the breaking member 651 is further removed here. Since the separating portion 654 is held by the elastic piece 630E of the holding member 640, the separating portion 654 of the breaking screw 651 can be removed together with the holding member 640. According to this, the separating portion can be more easily and simply attached. Can be removed.

  40, for example, if the elastic piece 630E of the holding member 640 is formed so as to be inclined with respect to the screwing direction of the breaking screw 651, the separating portion 654 of the breaking screw 651 is covered with the head. Since the separating portion 654 is held in an inclined posture with respect to the head main body 655 after being separated from the head main body 655, it is more desirable to make it difficult to reversely rotate the head main body 655.

(9) In the first embodiment, the separated separation portion 654 of the breaking screw 651 is held at a predetermined position by the elastic pieces 662R and 662L as the urging means and is covered by the housing member 658 as the restriction means. However, instead of this, the urging means may not be provided, and the breaking screw separating portion may be held at a predetermined position by the regulating means regardless of the urging force. For example, such a configuration can be obtained by not providing the elastic pieces 662R and 662L in the housing member 658 of the first embodiment.

(10) FIG. 41 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.

  41 differs from the breaking screw 651 in the first embodiment in that a head portion 614 is formed with a flange portion 617 extending in a radial direction at 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.

  The housing member 621 shown in FIG. 42 is fitted to the head 491 of the breaking screw 439 shown in FIG. The housing member 621 has a hole size in which the insertion hole 627 formed in the bottom plate 628 can pass through the head body 614 of the breaking screw 651 and cannot pass through the flange portion 617. The introduction notch (not shown) has the same configuration as the housing member 658 in the first embodiment except that the introduction notch (not shown) is also sized to guide the head body 614 of the breaking screw 651.

  41 to 42, according to the breaking screw 439 and the housing member 621, the flange portion 616 of the breaking screw 439 engages with the operation hole 622, and the head 491 of the breaking screw 439 comes out from the operation hole 622 to the outside. On the other hand, the flange portion 617 engages with the peripheral edge of the insertion hole 627 of the bottom plate 628 so that the head portion 491 of the breaking screw 439 cannot come out from the insertion hole 627. The portion 491 is reliably held in the state of being accommodated in the accommodation member 621.

  Further, the insertion hole 627 of the bottom plate 628 has a hole size through which the head main body 614 of the breaking screw 439 can be inserted. As shown in FIG. 42, the flange 617 is formed in the head main body 614 of the breaking screw 439. It is formed at a position with a gap d10 larger than the thickness t10 of the bottom plate 628 that is the lower surface portion of the housing member 621 from the end on the shaft portion 492 side. Accordingly, the bottom plate 628 has a slight margin (d10−t10) between the surface of the second mounting base sealing portion 432 and the flange portion 617 with which the end of the shaft portion 492 of the head body 614 of the breaking screw 439 abuts. Therefore, even when the breaking screw 439 is fastened, the housing member 621 can be freely rotated with respect to the breaking screw 439, that is, can be freely idled (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.

  For example, a housing member having a polygonal outer shape such as a rectangular parallelepiped such as the housing member 621 in the present embodiment or the housing member 658 in the first embodiment is a sealing portion having a polygonal internal shape corresponding thereto. An accommodating member having a cylindrical outer shape, such as the accommodating member 664 in the above-described embodiment, is inserted as much as possible into a sealing portion having a corresponding round inner shape. Although it is possible to make it difficult to rotate the housing member from the outside by adopting a configuration such that the housing member 621 is idled as described above, it is more reliable to loosen the breaking screw 439. Can be prevented. 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. 43 (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. 43 (b), a positive screw hole S15 is formed in one end face of the coil material S11, while in the head body S12 as shown in FIG. 43 (c). A knurl S17 is formed on an end face far from the screw hole S15.

3. Next, as shown in FIG. 43 (d), further header processing is performed, and the end of the head 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. 43 (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 of the head body S12 is cut. The screw thread is cut to form the shaft portion S14.

5. Next, as shown in FIG. 43 (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.

(11) 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.

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

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