  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 right side view of the pachinko machine 10, and FIG. 3 is a plan view thereof. FIG. 4 is a front view of the game board 30.

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 front frame (set) 14 is provided with a lower plate 15, a ball removal lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 (position on the left and right upper ends of the inner frame 12). The lower tray 15 serving as a ball receiving tray is provided in a substantially central portion, and has a role of stopping a game ball discharged from the discharge port 16 when an upper tray 19 described later becomes full. 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 launching device 38 includes a game ball launching handle 18 and a launching solenoid.
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).

The front frame 14 is attached to the inner frame 12 so that it can be opened and closed. Like the inner frame 12, the front frame 14 opens to the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be done. Moreover, the front frame 14 is attached so as to fit into the outer wall (rib) 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) of the inner frame 12, foreign matter (needle-like or A thin plate or the like, specifically, a wire, a piano wire, a celluloid plate, or the like) can be prevented. 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.

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

  Therefore, the 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 of the resin base. 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. 4, 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. 4 is a front view showing the configuration of the game board 30. Two pairs of general prize-winning ports 31 and 31 are positioned in a stepped manner at a slightly lower position on the left and right of the game board 30, and a starting hole 33 is disposed at the lower center of the game board 30. However, these sensors are provided on the back surface of the game board 30 and these sensors are connected to a main control board (main control device), which will be described later, through 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 detection sensors are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is paid out from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board.
In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

In addition, a decorative symbol display device 42 using a liquid crystal panel is disposed at the center of the game board 30, and through gates 34, 34 are disposed on the left and right side portions thereof. These through gates open and close the wings of the starting port 33, which will be described later, as a result of a predetermined lottery being performed by passing the game ball and winning.
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 32 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 of the inner rail 51 (upper left portion in FIG. 4). 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. 4: a portion corresponding to the tip portion of the outer rail 52). Accordingly, the game ball fired at a predetermined momentum or more hits the return rubber 54 and rebounds. On the inner side surface of the outer rail 52, a sliding plate as a long metal strip made of stainless steel is attached to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is worn.

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

A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and serves to guide the foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage. .
Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 4) and plates such as certificate stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a seal such as a certificate (S1, S2 in FIG. 4) 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. Further, the lower limit position of the game castle 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 (game board 30), a launch rail for guiding the game ball immediately after being launched from the game ball launcher 38 (see FIG. 6) is attached. The launch rail is fixedly attached to the resin base via a metal plate behind the launch rail, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail, and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It has come to be.

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

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

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

  Further, when the front frame 14 is closed, the shutter is pushed open by a ball passage rod provided on the back surface of the front frame 14 to be in a substantially horizontal state, so that the game balls discharged toward the discharge port are not leaked. It is discharged to the upper plate 19 through the passage ridge. 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.

  On the upper side of the inner frame 12, a front frame set open detection switch for detecting that the front frame 14 is opened with respect to the inner frame 12 is provided. When the front frame 14 is opened, it is output from the front frame set open detection switch to the computer for the hall (in the pachinko store). 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 3.
A substantially oval window 101 is formed on the front frame 14 so that most of the game area can be viewed from the outside. Specifically, the base member includes an opening that forms the window portion 101, and a substantially central portion on the left and right sides thereof has a shape that is curved and thinned relatively gently as compared with the upper and lower sides. The substantially central portion may be linear.

In addition, the front frame 14 is provided with a light emitting portion such as various lamps as one of the effect devices 700 around the periphery (for example, a corner portion). These light emitting units play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or when the blade is opened. For example, at the periphery of the window portion 101, an annular illumination portion 102 incorporating a light emitting portion such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting unit such as an LED is provided.

In addition, an upper plate illumination unit 104 having a built-in light emitting unit such as an LED is also provided around the upper plate 19.

  In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of the prize ball and error display lamps 810 and 813 (LED: which will be described later) that are lit when a predetermined error occurs. . Further, a small window portion 107 made of a transparent resin is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102. Since the predetermined portion of the small window portion 107 has a flat shape, the stamp attached to the lower right corner portion of the game board 30 can be suitably read from the flat portion of the small window portion 107 by a machine. Furthermore, although there are electrical lamps and LEDs for a prize opening etc. in the game area, such a light emitting unit also constitutes a part of the effect device 700.

  Further, as shown in FIG. 1, a ball rental operation unit 120 is disposed below the window unit 101, and the ball rental operation unit 120 is provided with a ball rental button, a return button, and a frequency display unit. It has been.

Done. The ball lending button is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. The The return button is operated when requesting the return of a card or the like inserted into the card unit.

  The frequency display unit displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not necessary for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate 19 without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As described above, the restriction mechanism 440 is configured such that the first engagement portion 414 of the opening / closing mechanism 410 is inserted into the insertion portion 434 when the first engagement portion 414 and the second engagement portion 433 are engaged. Then, after the engagement with the second engagement portion 433, the movement in the extraction direction opposite to the insertion direction is restricted.

  Here, the connection base member 430 will be described in detail. The connection pedestal member 430 is configured to be smaller than the substrate case 201. Among the substrate cases 201, as described above, one end side of the substrate case 201, that is, a corner on one end side (rear view, lower left side). (Position corner) and is configured to be sealed and connected. The connecting base member 430 is provided with a covering member 430A so as to cover the second engaging portion 433. The covering member 430A has a separate structure so as to be combined with the connecting base member 430, and at least one of them, here, the connecting base member 430 has a concave surface, and the other side, ie, faces the covering member 430A. The insertion portion 434 for inserting the first engagement portion 414 is formed by combining them. Specifically, the insertion portion 434 is formed in a tapered shape such that the entrance thereof becomes narrower from the entrance side toward the inside, and a plurality of, here, four guide ribs along the insertion direction. Is formed. In the drawing, reference numeral 430D denotes an engaging protrusion provided on a side portion of the covering member 430A, and is engaged with a corresponding portion of the connecting base member 430 when fitted.

The covering member 430A is provided with the second engaging portion 433. The thin plate of the second engaging portion 433 is slid from the entrance side to the locking protrusion 430C formed on the covering member 430A. Insert and lock.
The covering member 430A is configured to be smaller than the connection base member 430. When the connection base member 430 and the substrate case 201 are connected, the substrate case 201 is positioned on the removal direction side of the cover member 430A. In this state, the substrate case 201 and the connecting base member 430 are covered with each other.

(Function)
As described above, the opening / closing mechanism 410 for opening and closing the substrate case 201 in a state where it covers at least a part of the spherical assembly plate 460 and an exposed state is provided, and the opening / closing mechanism 410 and the substrate case 201 are provided. In addition, a connection base member 430 connected to each other is provided, and the substrate case 201 further includes a first connection sealing portion 450 connected and sealed to the connection base member 430, and the connection base member 430 includes: A second connection sealing part 432 connected and sealed with the substrate case 201 and a second engagement part 433 for the opening / closing mechanism 410 are provided, and the opening / closing mechanism 410 engages with the second engagement part 433. The first engagement portion 414 and a hinge fitting 412 having a shaft for opening and closing are provided, and one of the hinge fittings 412 has a screw connecting portion 401, The joint portion 414 and the second engagement portion 433 of the connection base member 430 are configured so that they cannot be released without leaving a trace of forced release such as destruction after both have been engaged, and the screw connection portion 401 is screwed to the ball assembly plate 460 from the side of the surface to which the game board 30 is attached, and after the ball assembly plate 460 is fixed to the back surface of the game board 30, The hinge fitting 412 can be removed without destroying the ball assembly plate 460 by preventing the connection and releasing the screw connection after the ball assembly plate 460 is removed. As a result, the hinge fitting 412 of the openable / closable board case 201 of the gaming machine can be attached with screws and cannot be removed after the assembly is completed. Without destroying the ball collection plate 460 by removing the screws, and removable from the sphere set plate 460, it is possible to improve the recyclability according to.
Then, the hinge fitting 412 is inserted into the connecting base 402 in a state after the hinge fitting 412 of the screw connecting portion 401 is crimped, and then, from the mounting surface side to the game board 30 to the connecting base 402. Since the mounting method in a pre-integrated state that can be screwed is adopted, the hinge fitting 412 must be caulked with the ball assembly plate 460 after being screwed to the connecting base 402. There is no inconvenience, and while it is possible to easily attach the hinge bracket 412 to the coupling base 402, it is possible to take a countermeasure against fraud.

  And, on the back surface of the ball assembly plate 460, a connecting base 402 protruding toward the back side of the gaming machine is provided by integral molding in a state where a space is formed on the front surface side, and the screw connecting portion 401 is The front connection bodies 401A and 401A that penetrate the shaft for opening and closing, and the front connection bodies 401A and 401A, and a screwing portion 401F that is integral with the front connection bodies 401A and 401A. A vertical slit 403 for inserting the screw fastening portion 401F and the front coupling bodies 401A and 401A is formed in a direction substantially parallel to the plane of the game board, and the front coupling body 401A of the screw coupling portion 401 is formed. , 401A for inserting 401A is formed to be continuous with the horizontal slits 404, 404 in a direction substantially perpendicular to the plane of the game board 30, and the connecting base 4 1 is provided with a screw receiving portion 405 that supports the screw fastening portion 401F by screwing from the front side, so that a hinge fitting 412 (screw fastening portion 401F and front coupling body 401A is attached to the ball assembly plate 460. , 401A) is formed by a base structure, but the vertical position and the horizontal slit 403, 404, 404 are formed and inserted into the connection base 402 while the position of the hinge fitting 412 can be set to a required height. In this way, the strength of the coupling base 401 is secured, and the hinge bracket 412 can be retrofitted instead of being integrally molded with the ball assembly plate 460, but a part of the hinge bracket 412 is coupled. It can be screwed inside the base 401, and can be removed from the outside after the ball assembly board 460 is attached to the game board 30 by screwing from the front side of the gaming machine. We were able to odd. Accordingly, it is not necessary to use a breaking screw, and the hinge bracket 412 can be removed as needed without being embedded by integral molding.

  The screw receiving portion 405 is integrally formed on the upper portion of the coupling base 401 so as to be cantilevered at one side so as to form the vertical slit 403 and the horizontal slits 404 and 404. The screw connecting portion 401 has a support portion 401D continuously extending from the screw fastening portion 401F, and is connected to the vertical slit 403 on one side of the connecting base 402 where the vertical slit 403 is located. Since the support base part 406 that contacts and supports the support part 401D located outside after the screwing part 401F is inserted is integrally formed with the connection base 401, the hinge bracket 412 is inserted. Since the vertical slit 403 and the horizontal slits 404 and 404 are formed so that they can be retrofitted by a method, the screw receiving portion 405 can be cantilevered as a result. Therefore, the load of the board case 201 and the like transmitted through the front coupling bodies 401A and 401A to the screw coupling part 401 of the hinge fitting 412 screwed here (the bending moment especially when the board case 201 is closed). However, the cantilever-supported screw receiving portion 405 is bent toward the inside of the connecting base, and this is supported by the support base portion 401D via the support portion 401D. The screw receiving portion 405 can be supported so as not to be bent. At this time, since the support base 406 is formed integrally with the connection base 401, the screw receiving part 405 can be protected against a load with sufficient strength.

Further, the screw fastening portion 401F of the screw coupling portion 401 is formed of a flat plate body, and the front coupling bodies 401A and 401A are formed in a U shape in a side view from both side portions of one end thereof, respectively. Since it is formed by bending, the screw connecting portion 401 of the hinge metal fitting 412 can be obtained with a simple structure in which a flat plate body is bent, and the supporting strength can be exhibited as a U-shape.
And the other of the hinge metal fitting 412 has rear coupling bodies 401B and 401B, and the rear coupling bodies 401B and 401B are connected to the first engagement portion 414 via a support surface portion 401C integrated therewith, and Since the support surface portion 401C abuts and supports the side surface of the connection base member 430, the other of the hinge bracket 412 has the rear connection bodies 401B and 401B, and the support surface portion 401C is integrated with this portion. Is brought into contact with the side surface of the connecting pedestal member 430 so that when the substrate case 201 is opened and closed, the opening and closing force can be transmitted via the support surface portion 401C, and the force acts only on the second engaging portion 433. In this way, the supporting force can be dispersed.

  Further, on the front side of the substrate case 201, the spacer 501 is opposite to the hinge fitting 412 of the substrate case 201 so that the spacer 501 opens and closes in a state of directly covering and exposing the ball assembly plate 460. The hinge bracket 412 is provided with a reinforcing member 401E, and the reinforcing member 401E penetrates into a part (concave portion) of the spacer 501 when the spacer 501 and the substrate case are covered. Thus, in the configuration in which the ball assembly plate 460 is covered with the spacer 501, the structure in which the reinforcing member 401E of the hinge metal fitting 412 enters a part of the spacer 501, and the load applied to the hinge metal fitting 412 is applied to the spacer 501. It can be transmitted and dispersedly supported. The reinforcing member 401E may enter the spacer 501 by forming a recess in the spacer 501 or by forming a slit in the wall surface. The contact state is caused by slight bending when a load is applied. As long as a supporting action can be obtained, the contact state may not always be present.

  Further, guide ribs 407 and 407 for guiding both side portions of the screw connection portion 401 at internal positions corresponding to the horizontal slits 404 and 404 of the connection base 402 and on an extension line of the upper surface of the support base portion 406, respectively. When the screw connection portion 401 of the hinge metal fitting 412 is inserted into the connection base 402 through the vertical and horizontal slits 403, 404, 404, the screw connection portion 401F of the screw connection portion 401 and the screw fixing portion 401F are continuously connected thereto. When the extended support portion 401D is placed on the upper surface of the support base portion 406 and slid and inserted, the both side portions of the screwing portion 401F are passed from the place where the upper surface of the support base portion 406 is passed. The guide ribs 407 and 407 can be smoothly inserted into the connection base 402 while being guided.

  Further, a reinforcing rib 408 extending in the vertical direction is formed in the connecting base 402 at a substantially central position in the width direction of the inner wall on the back side where the screw connecting portion 401 is inserted, and an upper end of the reinforcing rib 408 is formed. Since the portion terminates at a position where the screw fastening portion 401F is supported from below, the position can be stabilized when the screw coupling portion 401 is inserted into the coupling base 402, and thus the screw fastening portion The screw fixing operation for the screw receiving portion 405 of 401F can be easily performed, and the bending of the screw receiving portion 405 by supporting the end portion of the screw connecting portion 401 can be opposed.

  And the rear connector 401B, 401B located on the one side of the substrate case 201 is outside the front connector 401A, 401A located on the one side of the substrate case 201. The cross section is formed in an L shape from the rear coupling bodies 401B and 401B to the first engaging portion 414, and the first engaging portion 414 is a predetermined distance from the rear coupling bodies 401B and 401B. Since the board case 201 is supported by the hinge bracket 412 on the substantially intermediate part side in the longitudinal direction of the board case 201, for example, at the end of the board case 201 in the longitudinal direction side. Compared to connection support, stable support can be achieved. For this purpose, the first engagement protrusion piece 414 is separated from the rear connection bodies 401B and 401B by a predetermined distance. Unisuru must, by this portion and L-type structure, and can give sufficient strength with light weight as possible, it is the support of the board case 201 can be firmly stabilized.

  Further, the two shafts 411 and 411 (the shaft shape is not shown) of the hinge metal fitting 412 are fixed to the front connecting members 401A and 401A and the rear connecting members 401B and 401B by caulking, respectively. Therefore, once the connection is made, it cannot be released, and thus the risk of being easily separated by a hinge fitting such as a screw connection and replacing the board case can be avoided. Injustice targeting 412 can be avoided.

  The present invention has been described based on one embodiment. However, the present invention is not limited to the above embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. It can be easily guessed.

  The present invention can be appropriately implemented as long as it is a gaming machine including a board case and having a function of opening and closing the board case, and its application range is wide.
