Description

  The present invention relates to a gaming machine represented by a pachinko machine.

The pachinko machine is configured such that a game ball launched by a launching device passes through a guide passage and is guided to a game area, and a game is played using the behavior of the game ball in the game area.
The game area is an area where game balls set on the front of a game board (such as veneer or synthetic resin) flow down. The game area is made up of winning holes and a large number of game nails (guide nails). A change is given to the behavior of the sphere.

Generally, about 60 game balls are fired per minute by the launcher. The game ball collides with a game nail (guide nail) or the like and changes the flow direction, and wins the winning opening or enters the out opening provided at the lower part of the gaming area and is guided to the back side of the gaming board. The In addition, the game ball that has won the winning opening is guided toward the lower part on the back side of the gaming machine through a winning passage provided in the winning device and a discharge passage provided in the ball collecting plate.
As for the gaming machine having such a configuration, for example, the following documents can be cited.

Japanese Patent Laid-Open No. 2007-20642.

The game nail (guide nail) is gradually deformed by continuing to receive the impact of the fall of the game ball, and the collision angle of the game ball changes from the predetermined state, and the flow path of the game ball after the collision changes. In order to prevent such a situation, the angle of the game nail may be adjusted (such as returning to a predetermined setting state).
This game nail is generally made of brass, which is resistant to corrosion. However, especially when the pachinko machine is operated for a long period of time, the game nail breaks due to the impact of the game ball and angle adjustment. May end up. When these game nails are broken, most of them are broken at the base.

These game nails are arranged in consideration of the behavior of the game ball and the positional relationship with other components, so if the game nail breaks, it is necessary to drive a new game nail into the same position There is. In this case, normally, a new game nail is struck as it is from above the game nail folded at the base, and the broken game nail is penetrated to the back side of the game board and discharged.
In particular, the pair of game nails above the winning opening (for example, the start opening) is a very important gaming nail for determining the winning frequency, and frequent game nail collision and adjustment for deformation are performed. The game nail is broken more frequently.
When the game nail at the winning opening is ejected by ejecting it to the back side of the game board, it may enter a predetermined game ball passage on the back side of the game board, resulting in clogging of the balls.

The present invention has been devised in view of the above problems, and aims to suppress the spherical clogging in the passage by the fall in the predetermined path of the gaming nails broken discharged to the game board rear surface To do.

  Thus, by providing the deflecting member on the game board, it is not necessary to provide a separate member for laying the deflecting member, and by configuring the deflecting member with a metal plate material, a normal game nail made of brass can be obtained. When it is discharged and collides with it, it can be surely deflected.

Means 14: In the gaming machine of means 1 to means 13,
The gaming machine is a pachinko machine.

As a basic configuration of a pachinko machine, an operation handle is provided, and a ball, which is an example of a valuable object, is launched into a predetermined game area in accordance with the operation of the operation handle, and the ball is disposed at a predetermined position in the game area. In other words, the identification information (such as symbols) that is dynamically displayed on the display device is determined and stopped after a predetermined time on the condition that a winning (or passing through the operation gate) is required for the operation port. In addition, when a special gaming state occurs, a variable winning device (specific winning opening) disposed at a predetermined position in the gaming area is opened in a predetermined manner so that a ball can be won, and a value corresponding to the number of winnings is obtained. Examples include values to which values (including not only premium spheres but also data written on a magnetic card, etc.) are given.
In such a pachinko machine, to replace a broken game nail for a prize opening with a new one, when a new game nail is driven from the top of the broken game nail, the broken game nail However, in this case, a discharge game nail receiving portion is provided below the virtual extension trajectory in the driving direction of the game nail for the prize opening. The discharged broken game nail is received by the discharged game nail receiving portion without falling into the passage portion connected to the winning opening. As a result, it is possible to avoid the clogging of the game balls, which is caused by the broken game nails falling into the passage portion.

  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 stepwise on the left and right sides of the game board 30 and a starting port 33 (upper starting port 33a and lower starting port 33b) is disposed below the center. Corresponding to these, a ball detection sensor (starting port detection sensor 33c) is provided on the back surface of the game board 30, and these sensors are connected to a main control board (main circuit) (to be described later) through electric wiring (not shown). Control device).
When a game ball enters the general winning ports 31, 31 and the start port 33, it is detected by the detection sensors (the start port detection sensor is 33c), and based on the output of the detection sensor, When a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15) 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 (starter detection sensor 33c) are taken into a main control board, which will be described later, and the main control board issues a payout command (in accordance with the winning situation each time) The number of game balls paid out) is transmitted to the payout control board. Then, a predetermined number of game balls are paid out by the output of the payout control board. When a big win comes out in the lottery, the big prize opening 37 below the start opening 33 is opened under a predetermined condition.
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.

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.

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 for supporting the screw fastening portion 401F from the front side, the hinge assembly 412 (the screw fastening portion 401F and the 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 of the hinge metal fitting 412 are fixed with respect to the front connection bodies 401A and 401A and the rear connection bodies 401B and 401B by caulking, respectively. Once this is done, it cannot be released. This makes it possible to avoid the risk that the hinge case such as screw connection can be easily separated and the board case can be replaced. It can be avoided.

(Feature configuration)
Characteristic portions of the present invention in this embodiment are as shown in FIG.
That is, in this gaming machine, a plurality of game nails 150 are implanted in a game area where game balls flow down, and the game area includes a start port 33 (here, an upper start port 33a and a lower start port 33b: FIG. 4). And a ball assembly plate 460 provided on the back surface of the game board 30 and having a discharge passage 461 connected to the starter port 33. The starter port 33 is provided above the starter port 33. A pair of game nails 150 are driven into the game board 30 at a predetermined interval.
A discharge game nail receiving portion 151 is provided on the back side of the game board 30 below the virtual extension trajectory T in the driving direction of the game nail 150 for the start port 33 and above the passage portion. It has been.

In the specific configuration for the start port 33 described above, a game area where a game ball flows down is formed on the front side, and a winning opening (a start port 33 and other general winnings) through which the game ball can enter the game area. A game board 30 provided with a pair of game nails 150 provided on the upstream side of the game area and at positions corresponding to the opening width of the prize opening. It is an example of a gaming machine provided, and is a part of a passage for guiding a game ball that has entered the winning opening, and is located on the back side of the game board 30 and has a groove-like passage portion 461A that is open upward. (Connecting the start port 33 and the discharge passage 461), and a predetermined location on the back side of the game board 30 including a location directly below the virtual extension trajectory T in the direction in which the game nail 150 is driven. Between the virtual extension locus T and the passage portion 461A In the position, in which the discharge gaming nail receiving portion 151 which the player nail 150 receives the game nail 150 when dropped hammered out on the back side of the game board 30 is provided.
A side wall 461B that forms the groove shape of the passage portion 461A is provided so that the depth of the groove of the passage portion 461A is equal to or less than the diameter of the game ball.
As can be seen from the above example, it may be understood that the passage portion 461A may accompany the general winning port 31, the big winning port 37, and the like other than the start port 33.

Here, the relationship between the game board 30 and the game nail 150 will be described in detail.
The game board 30 is composed of a plywood (a veneer board or the like) as described above, and its thickness is usually about 18 mm (or 20 mm). The game nail 150 to be driven here is generally 35 mm in total length, and is about 17 mm driven into the game board 30 so that 18 mm protrudes from the board surface. That is, the game nail 150 is driven in a state that does not penetrate the game board 30. The game nails 150 are driven by a planting device that is computer-controlled with respect to the game board 30 that has been previously drilled.

  A large number of such game nails 150 are driven on the game board 30 as guide nails in a game area, lifepins of a windmill, or life nails of a prize opening (general prize opening, start opening, through gate, etc.) Both sides of the opening of the mouth 33a are driven as a life nail at a predetermined interval. The pair of game nails 150 for the upper start port 33a is driven at a predetermined interval. However, along with a long-term game, the game ball is deformed by collision and forced to adjust the nails. If such nail adjustment is frequently performed, the base of the game nail 150, that is, the position near the game board 30 frequently breaks.

  In this case, it is necessary to replace the game nail 150 with a new one, but since it is a life nail, its driving position cannot be changed. Therefore, the new game nail 150 is removed from above the broken game nail 150. A method of driving in the stacked state will be adopted. As a result, the broken game nail 150 is pushed out by the new game nail 150 and falls to the back side of the game board 30. However, since the passage portion 461A for guiding the game ball entered from here is provided on the back surface of the start port 33, and the discharge passage 461 of the ball collecting plate 460 connected to the passage portion 461A is located, the above-mentioned fall has occurred. The broken game nail 150 often dropped from the passage portion 461A to the discharge passage 461 and became clogged with balls.

Therefore, the above-described discharged game nail receiving portion 151 receives the broken game nail 150 when it is pushed out of the game board 30 so as not to fall into the discharge passage 461 of the ball collecting plate 460 from the passage portion 461A. . Here, the discharge game nail receiving portion 151 is provided on the ball collecting plate 460 so as to close the upper surface of the passage portion 461A for the start port 33. The structure is such that at the top of the ball assembly plate 460, directly below the virtual extension trajectory T in the driving direction of the game nail 150 for the start port, the arc surface is directed upward and the bottom surface portion is directed to the game board side. The substantially semi-conical portion, that is, the inclined wall 151A, and the substantially semi-conical portion, that is, the flat plate portion 151B continuous with the cutting portion (cut through the conical perpendicular) of the inclined wall 151A, Is integrally formed with the ball assembly plate 460.
The inclined wall 151A has an upper end positioned inside the pair of game nails and is inclined in the left-right direction. The inclined wall 151A has a position of the upper end of the game ball passing through the passage portion 461A. While being set to a position higher than the height, the portion corresponding to the position directly above the side wall 461B is set to a position lower than the height of the game ball passing through the passage portion 461A.
The inclined wall 151A includes an inclined surface 151a that inclines toward the left and right and also inclines toward the downstream side of the passage portion 461A.

  Here, the discharge game nail receiving portion 151 has a substantially semi-conical portion, that is, an inclined wall 151A in a direction away from the back surface of the game board 30, and a flat plate portion 151B in both lateral directions of this length. Further, a flat plate portion 151B is formed over a length of about 10 mm in a direction away from the back surface of the game board 30, and the game board 30 on which the substantially semi-conical portion, that is, the inclined wall 151A is located. In the width direction, the width is set to about 70 mm, and on the rear side, the width is set to 65 mm. The width of 65 mm and the length (depth) of about 10 mm form a portion where the substrate is laid from the back side. Incidentally, here, the length in the vertical direction of the substrate laying is 50 mm, which is rectangular in the rear view.

  Further, a recess 152 is formed in a portion corresponding to the back side of the game board 30 in the virtual extension locus T in the driving direction of the game nail 150 for the start port 33. The recess 152 has a notch depth of about 1 mm. Therefore, when the game nail 150 is broken at the base, the length remaining in the game board 30 is about 17 mm, and the game is broken by driving a new game nail by a predetermined length, that is, 17 mm. When the nail 150 is pushed out, the broken game nail 150 just reaches the recess 152 of the notch and surely falls off. And this recessed part 152 has comprised the cone shape by which the vertex was turned to the inner side of the game board 30 here. By using such a conical recess 152, the end of the game nail 150 is easily slid down at the moment the folded game nail 150 is pushed out of the game board 30 with the inclination angle of the cone, and the discharge is prevented. It can be done reliably.

Summarizing the gaming machines of the above-described embodiments, the detecting means (starting port detection switch 33c) for detecting the game ball that has entered the winning port (starting port 33), and a lottery for performing a predetermined lottery based on the detection Means, that is, an internal random number counter on the main control board, display means for displaying predetermined information selected based on the lottery result of the lottery means, that is, the symbol display device 42, and attached to the game area. In addition, a winning device having the above winning opening, that is, a starting winning device (starting port 33 or the like) is provided.
In such a gaming machine, the winning device is provided with the passage portion 461A, and the display means 42 and the winning device are vertically arranged with respect to a central region in the width direction of the gaming region, The pair of game nails 150 are located between the display means 42 and the winning port (starting port 33) provided in the winning device.

(Function)
Since the structure is as described above, when the game nail 150 for the start port 33 is replaced with a new one, when the new game nail 150 is driven from above the broken game nail 150, the broken game nail 150 is The game board 30 is discharged to the back surface side. At this time, a discharge game nail receiving part 151 is provided below the virtual extension locus T in the driving direction of the game nail 150 for the start port 33. Thus, the broken game nail 150 discharged from the game board 30 is received by the discharged game nail receiving portion 151 without falling into the discharge passage 461 of the ball assembly plate 460 connected to the start port 33. Thereby, it is possible to avoid the clogging of the game balls, which is caused by the broken game nail 150 falling into the discharge passage 461.

  The discharge game nail receiving portion 151 provided below the virtual extension trajectory T in the driving direction of the game nail 150 for the start port 33 closes the upper surface of the discharge passage 461 for the start port 33. Thus, the broken game nail 150 discharged from the game board 30 by driving a new game nail 150 from above the broken game nail 150 is connected to the start port 33. Can be reliably prevented from falling into the discharge passage 461 and can be received by the discharge game nail receiving portion 151.

  In addition, the discharge receiving portion 151 has a substantially half of which the arc surface is directed upward and the bottom surface portion thereof is directed to the game board side immediately below the virtual extension locus T in the driving direction of the game nail 150 for the start port 33. A conical portion, that is, an inclined wall 151A, and a flat plate portion 151B continuous to a cutting portion of the inclined wall 151A, are formed integrally with the ball assembly plate, thereby allowing the game board 30 to The discharged broken game nail 150 is directly received by its substantially semi-conical portion, that is, the inclined wall 151A, without dropping with a step, and the inclination of the substantially semi-conical surface 151A causes The flat plate portion 151B can be slidably moved so as to be stably supported, and not only can the fall to the discharge passage 461 be prevented, but also the loose fall can be prevented. From falling unexpectedly location on the back surface side of the sphere set plate 460 in a state in which the nail 150 is jumping be avoided in advance.

  Normally, when the game nail 150 is driven into the game board 30, the game nail 150 is driven slightly shorter than its thickness, not through the game board 30. Therefore, when the game nail 150 is broken from the base, the length of the broken game nail 150 remaining on the game board 30 is shorter than the thickness of the game board 30, and the game nail 150 broken from the base is When a new game nail 150 is driven from above, a concave portion 152 exists in a portion corresponding to the back side of the game board 30, so that the folded game nail 150 shorter than the thickness of the game board 30 is located at the concave portion 152. It will leave 30. Therefore, it is not necessary to drive a new game nail 150 for an extra length in order to discharge the broken game nail 150, and the broken game nail 150 can be sufficiently discharged by stopping at the driving position at an appropriate position. is there.

(Modification 1 of the discharge game nail receiving portion 151)
As shown in FIG. 13, here, the discharge game nail receiving portion 151 includes a game nail receiving portion 153. Here, the game nail accommodating portion 153 is formed in the substantially semi-conical portion, that is, the pocket portion formed on the boundary between the inclined wall 151A and the flat plate portion 151B, that is, the pocket portion with the curved surface facing upward, ie, the groove shape. The holding portion 153A. When the broken game nail 150 is discharged from the game board 30 by the pocket-shaped, that is, groove-shaped holding portion 153A, after slipping down the substantially semi-conical portion, that is, the inclined wall 151A, Therefore, it is possible not only to prevent the ball assembly plate 460 from dropping to the discharge passage 461 but also to prevent the ball assembly plate 460 from falling to the back side.

Specifically, the inclined wall 151A has an upper end positioned on the inner side of the pair of game nails and is inclined in the left-right direction. The inclined wall 151A has the upper end positioned at the passage portion 461A. The position corresponding to the position directly above the side wall 461B is set at a position lower than the height of the game ball passing through the passage portion 461A, The inclined wall 151A includes an inclined surface 151a that inclines toward the left and right, and also inclined toward the downstream side of the passage portion 461A, and the groove-like shape is formed on the downstream end side of the inclined surface 151a. The holding portion 153A is formed.
As a structure of the game nail accommodating part 153 as described above, a cylindrical container type may be used.

(Modification 2 of the discharge game nail receiving portion 151)
As shown in FIG. 14, here, a deflection member 154 that deflects the discharge direction of the discharge game nail 150 obliquely downward and rearward is provided on the virtual extension trajectory T in the driving direction of the game nail 150 for the start port 33. ing. Here, the deflecting member 154 is made of a metal plate material (here, a steel plate) bent at a predetermined angle, and is provided on the ball assembly plate 460 with screws.
Incidentally, here, on the virtual extension trajectory T, the inclined surface of the deflecting member 154 is positioned at a position 10 mm away from the game board 30, so that about 5 mm in the game board 30, Instead of going straight, it can be deflected obliquely backward and downward and discharged. If the deflecting member 154 is too close to the game board 30, the length of the game nail 150 remaining inside the game board 30 becomes long, and the outlet portion of the game nail 150 of the game board 30 is expanded and deformed by the resistance colliding with the deflecting member 154. There is a possibility that it may be allowed to occur, which is not preferable.
By providing the deflection member 154 in this way, it is not necessary to secure a space necessary for the full length of the broken game nail to be pulled out on the back surface of the game board 30, and the space on the back side of the game board can be used effectively.

(Modification 3 of the discharge game nail receiving portion 151)
As shown in FIG. 15, the discharge game nail receiving portion 151 is constituted by a deflection portion-equipped accommodation portion 155 in which the game nail accommodation portion 153 and the deflection member 154 described above are integrally formed. In this case, the above-described game nail accommodating portion 153 is formed so as to cover the discharge passage 461 of the ball assembly plate 460 from the passage portion 461A, and while preventing the game nail 150 from dropping from the passage portion 461A to the discharge passage 461. The game nail 150 can be accommodated in the game nail accommodating part 153 while changing the direction of discharge of the broken game nail 150 to be inclined rearward and downward.
And this accommodating part 155 with a deflection | deviation part is comprised with the metal board | plate material which was bend | folded by the predetermined angle here and was curved for accommodation, and this accommodating part 155 with a deflection | deviation part is the game board 30. A member laid on the back surface of the spacer 501 is fixed to the front side portion of the spacer 501 with a screw.
Note that the deflecting portion-equipped accommodating portion 155 is also provided not on the spacer 501 but on the game board 30 side.

(Modification 4 of the discharge game nail receiving portion 151)
FIG. 17 is a rear view of the ball assembly plate. As shown here, the upper surface of the discharge game nail receiving portion 151 of the ball assembly plate 460 is W-shaped in back view, that is, two spaces between the game nails. The two groove portions 156 corresponding to the above are formed.
The groove 156 serves as a tray when the broken game nail 150 is pushed out of the game board 30 by the new game nail 150, and prevents free fall downward. There is no possibility of falling from the passage portion 461A to the discharge passage 461 of the ball collecting plate 460 and causing clogging.

  The present invention can be implemented as appropriate as long as the game nail is equipped with a ball assembly plate having a discharge passage connected to the start opening of a game nail that is driven into the side of the start opening of the game board. It is wide.
