In order to achieve fraudulent behavior from the game machine, it is necessary to move the parts of the gaming machine greatly. Therefore, the pivot axis for opening and closing the board box is the pivot axis of the inner frame. It is preferable to install on the opposite side in the direction.
The “various electrical components laid on the back of the game board and the ball assembly board provided here” in the present invention refers to a relay board, a starting port, a variable winning device, a big winning device, and the like.
The spacer may be called an intermediate member or a space occupying member, and is interposed between the ball assembly plate and the substrate box, and surrounds a predetermined electrical component on the rear surface of the ball assembly plate. And a partition wall having a plurality of walls that partition the gap between the back surface of the ball assembly plate and the board box, and the main purpose is to It is something that can be provided as a means of avoiding fraud due to the presence of space in between.
In addition, the place where the holding portion is provided where the substrate box is covered when the substrate box is in the covering state is, for example, the spacer or the ball assembly plate.

The gaming machine according to the present invention has as means 1,
A ball assembly board is provided on the back side of the game board, and the ball assembly board is formed with a discharge area (discharge bowl) for discharging the game balls that have entered the prize opening to the lower side of the game machine on the back side of the game board. A connecting pedestal member that supports the board box is rotatably provided, the board box is attached to the connecting pedestal member, and the board box covers a back surface of the game board and is exposed. A gaming machine that can be freely opened and closed,
A spacer is interposed between the ball assembly plate and the substrate box, and the spacer is configured to be non-removable when the substrate box is in a covering state,
The spacer defines a gap between a peripheral wall extending in the front-rear direction of the gaming machine so as to surround a predetermined electrical component on the rear surface of the ball assembly plate, and a space between the rear surface of the ball assembly plate and the board box. A partition having a plurality of walls,
A connection base sealing portion connected to the connection base member and the substrate box is provided on the connection base member and the substrate box so that the substrate box cannot be moved away from the connection base member without leaving a trace. When the stop is released, the substrate box can be displaced with respect to the connection base member,
A holding portion is provided at a location covered by the substrate box when the substrate box is in a covering state,
The holding unit is in a holding state in which the substrate box is held in a closed state by rotating the substrate box in a covering direction, and in the closed state, the substrate box and the connection base member are in a sealed state. Sometimes, it is configured to allow the displacement of the substrate box only when the sealing is released and to release the holding state.
It is characterized by that.

  By being configured in this manner, the spacer between the ball assembly plate and the substrate box fills the space between the two, making unauthorized intervention from both difficult and making the spacer of the substrate box Since the holding portion is provided at the portion covered by the substrate box when the substrate box is in the covering state, the holding state of the covering state of the substrate box cannot be easily released. In other words, it is possible to prevent unauthorized action on the electrical components on the back side of the game board by releasing the covering state. Furthermore, if necessary, the substrate box is displaced with respect to the connection base member by releasing the sealing of the connection base sealing portion between the substrate box and the connection base member, thereby holding the holding portion. The state is released to release the covering state of the substrate box, and at the same time, the substrate box can be detached from the connecting base member.

Mean 2: In the gaming machine of means 1,
The substrate box and the connection base member are slidably engaged within a predetermined range, and the connection base sealing portion is sealed in a state where the substrate box is in a covering state and is held by the holding portion. The holding state of the holding portion is released when the is released and is slid within the predetermined range, and the substrate box can be shifted to an exposed state together with the connecting base member.

  As described above, when the board box and the connection base member are slidably engaged, and the seal of the connection base sealing part is released and is slid within the predetermined range, the holding state of the holding part Is released, and the board box can be moved to an exposed state together with the connection base member, so that the connection release of the connection between the board box and the connection base member due to the release of the sealing of the connection base sealing part is performed. Since the holding state of the holding portion (the covering state of the substrate box) can be released using the above, a series of operations for releasing the sealing can also be used for releasing the covering state of the substrate box.

Mean 3: In the gaming machine of means 2,
The removal direction of the substrate box with respect to the connection base member and the slide direction of the substrate box for releasing the sealing of the connection base sealing portion are the same direction.

  Thus, the holding release of the holding portion is achieved by setting the direction in which the substrate box is removed from the connection base member and the sliding direction (displacement direction) of the substrate box for releasing the holding state of the holding portion to be the same direction. The structure for obtaining the operation in the specific direction of the substrate box for the purpose is not required, and both the operation of releasing the sealing of the connecting base sealing portion and the release of the holding state of the holding portion are made one. be able to.

Means 4: In order to achieve the above object, means 4
A game board in which a game area where game balls can flow down is formed on the front side,
A board box in which a control board for controlling a predetermined game is accommodated, a connecting base member that supports the board box so as to be opened and closed, a holding part that holds the board box in a closed state, and a base to which the connecting base member is attached An attachment means having an attachment part, an electrical component attachment part to which a predetermined electrical component is attached, and a rear side of the game board,
A peripheral wall extending in the front-rear direction of the gaming machine so as to surround the predetermined electrical component at least in the closed state, and between the back of the gaming board and the board box at least in the closed state Each of the mounting means and the board box is provided with a partition section having a plurality of walls that are arranged and have a plurality of walls that partition the gap between the back of the game board and the board box,
A gaming machine configured to be maintained in a state in which the electrical component is covered by setting the substrate box in the closed state to be held by the holding unit,
The connection pedestal member and the board box have a shape in which a mutual attachment / removal direction is regulated to a predetermined direction, and a configuration in which the connection base member and the board box are changed to an attached state and a detached state by moving each other by a predetermined amount in the restricted state In the mounted state, the sealing member is in a state in which the substrate box cannot be moved away from the connection base member without leaving a trace at each of the opposing positions of the connection base member and the substrate box. A pedestal sealing part connected by is provided,
The holding portion is provided in a region that is in the covering state in the closed state, and the substrate box attached to the connection base member is rotated from the open state to the closed state. Accordingly, the substrate box is received and held, and in the holding state, the rotation of the substrate box in the direction to be in the open state is restricted and the movement in the direction to be in the detached state is allowed. And
The holding state by the holding portion is released by moving the substrate box in the detaching direction by a specific amount shorter than the predetermined amount, and the substrate box is configured to be rotatable in the direction to be in the open state. It is characterized by being.

In such a configuration, by providing the peripheral wall, at least when the board box is in a closed state, predetermined electrical components (detection means such as a start opening switch and a large winning opening switch, blades in the start winning apparatus, and variable Driving means for driving an opening / closing member such as a door in the winning device, a harness electrically connected to these, a harness electrically connected to a control board for controlling the special lottery lottery, etc., or the control board and others The relay board that relays the electrical connection of the electrical parts is covered, and it is difficult to contact the predetermined parts from the outside. In addition, by providing a partition part, at least when the board box is in a closed state, the space between the board box and the back of the game board (in the vicinity of the control board and predetermined electrical components and hidden behind the board box) A space that is very difficult to place an illegal substrate or the like, such as a difficult region, is partitioned, and for example, there is no large space for concealing the illegal substrate or the like. Further, since the holding unit for holding the substrate box in the closed state is provided in a region that is covered in the closed state of the substrate box, as in the case of the predetermined electrical component, the holding state of the substrate box by the holding unit is directly set. It becomes difficult to operate and release the holding unit. Therefore, the predetermined electrical component is maintained in a covered state, and an illegal act due to a modification to the predetermined electrical component or an unauthorized substrate is prevented.
The holding portion in the state where the substrate box is held restricts the rotation of the substrate box in the opening direction, and allows the substrate box to move in the direction of detachment from the connection base member. Therefore, when each connecting base sealing portion is sealed by the sealing member, the substrate box cannot be opened, and the substrate box cannot be opened. In the case of opening the board box, since the seal of the joint base sealing part is released, leaving a trace of the release of the seal at a predetermined location of the gaming machine, the above-described illegal acts are performed. In the case of fraud, fraudulent acts can be detected at an early stage by the trace. In addition, it is not necessary to provide a sealing mechanism for keeping the substrate box in a closed state and preventing the substrate box from being opened without leaving a trace, separately from the connecting base sealing portion. Furthermore, when an unauthorized person illegally cancels the sealing state of the connecting base sealing portion and tries to open the substrate box, the holding portion can be simply rotated in the direction of opening. This movement is restricted by this, and it is difficult for a fraudster to check because the holding part is covered with a board box etc., so the board box is opened even after leaving a trace due to release of sealing. It is possible to suppress fraudulent acts that are performed with the knowledge that traces remain in the gaming machine.
Since the holding state by the holding portion is released by moving the substrate box with respect to the connecting base member by a specific amount (an amount shorter than the amount to be changed between the attachment state and the separation state) in the removal direction, for example, When it is desired to inspect or clean predetermined electrical components, these operations can be performed while the substrate box is opened together with the connection base member without being completely removed from the connection base member.
Since the substrate box is configured to be held by the holding portion with the rotation from the open state to the closed state, there is no need to move in a direction other than the rotation when the substrate box is to be closed, A complicated work is required when changing from the closed state to the open state, and conversely, when changing from the open state to the closed state, a complicated work is not required. In addition, as described above, the substrate box is held by the holding portion in accordance with the rotation from the open state to the closed state, so that the sealing operation between the substrate box and the connecting base member is performed at any point in the gaming machine manufacturing process. It can be set as the structure by which it will not be limited. For example, the work of sealing the substrate box and the connecting pedestal member may be performed before being brought into the factory due to the reason for anti-fraud measures or because it requires a skillful technique because it is sealed in a complicated process. is there.

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) 12 b 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 to 6 is detachably mounted on the rear side of the resin base 20. As shown in FIG. 6, the game board 30 is made of a rectangular plywood, one corner of the upper part is dropped (described later), and the peripheral edge abuts on the back side of the resin base 20 (inner frame 12). It is attached 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. 6, the corner is dropped (notched) 720 in a substantially triangular shape (the notch is an arc line but becomes a substantially triangular notch).

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 6 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 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 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 (upper left portion in FIG. 6). 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. 6: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner side surface of the outer rail 52, a sliding plate as a long metal strip made of stainless steel is attached to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is worn.

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

A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and serves to guide the foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage. .
Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 6) and plates such as 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 sticker such as a certificate (S1, S2 in FIG. 6) 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 170 for guiding the game ball immediately after being launched from the game ball launching device 38 is attached. The firing rail 170 is attached and fixed to the resin base 172 via a base plate 171 (a member for attaching the game ball launching device 38) which is a metal plate (here, an aluminum alloy) behind the firing rail 170, and a predetermined launch. It is configured to extend linearly at an angle (launch angle).
Accordingly, the 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 170, and thereafter, into the predetermined game area through the ball guide path of the rail unit 50 as described above. Guided.

  Further, there is a gap of a predetermined interval between the firing rail 170 and the rail unit 50 (guidance rail), and a foul ball passage is formed below the 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.

  As shown in FIG. 5, the game ball launcher 38 supplies game balls one by one to the ball feeding mechanism 173 from the ball outlet on the front frame 14 side (ball outlet leading from the most downstream portion of the upper plate 19). Then, the gate lever 173A provided in the ball feeding mechanism 173 is operated by the solenoid to supply the game balls one by one onto the firing rail. Further, the game ball launcher 38 is provided with a rhinocele-shaped conical hitting portion 38A made of synthetic resin and fixed to the tip of the shaft portion 38B, and the game is accompanied by the piston movement of the hitting portion 38A by excitation of the solenoid. A ball is fired.

  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 6.
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 the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks during the jackpot gaming state to notify that the jackpot gaming state is in progress. 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. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. 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.

  The relay board 470 is a board that relays the electrical connection between the main control board and a plurality of electrical components. In the case of this embodiment, the relay board 470 is arranged at a place where fraud is easily made or is not easily noticed. (1. It is shielded by the main control board when viewed from the back by being arranged on the front side of the main control board, 2. It is arranged at a place where wiring connected to the main control board passes. It is located between the main control board and a predetermined winning device arranged in the game area, or in a place where a wiring connecting the main control board and the winning detection switch passes) It can be said that this is an electrical component that is easily performed. The electrical components connected to the main control board via the relay board 470 entered the solenoid that opens and closes the door of the variable winning device 474, the solenoid that opens and closes the blades of the start winning device 476, and the big prize opening. For example, a switch for detecting a game ball. Among these, a switch that detects a game ball that has entered the grand prize opening must not be detected even though a special game state where a predetermined number of balls have been triggered is detected. It is highly likely to become a target when an illegal act such as delaying the end of the special game state and acquiring more game balls than usual during the special game state, and open the blade for the solenoid that opens and closes the blade In cases where fraudulent acts such as forcing the wings to open forcibly and letting many balls into the starting port make lots of lottery to make it easier to derive a special gaming state despite not being the opportunity to There is a high possibility of being a target, and many solenoids that open and close the doors are forced to open the doors even though they are not in a special gaming state, and make many balls into the big prize opening. It is those likely to be targeted when the fraud such win game balls, is considered to be a target of fraud also these electrical components. In addition, the switch for detecting the game ball that has entered the start port 33 is connected to the main control board without going through the relay board 470, but the lottery result becomes a hit result by operating the detection timing. This harness is placed between the main control board and the back of the game board because it is highly likely to become a target when an illegal act such as forcibly generating a gaming state and acquiring a large number of game balls is performed. ing.

Here, in order to clarify one feature of the present invention, the following configuration is shown.
In other words, the game board (game board 30) having a game area in which a game ball can flow down is formed on the front side,
A board box (first board case 201A) in which a control board (control board 80) for controlling a predetermined game is accommodated, a connection base member (connection base member 430) that supports the board box so as to be opened and closed, and the board A holding part (holding part 505) for holding the box in a closed state, a base mounting part (a shaft support part 501 and a bearing groove 504B as a bearing part) to which the connecting base member is attached, and an electric part mounting part to which a predetermined electric part is attached (Ball assembly plate 460), and mounting means (ball assembly plate 460 and first spacer 501) provided on the back side of the game board,
A peripheral wall (a first spacer peripheral wall 502 and a ball assembly peripheral wall 462) extending in the front-rear direction of the gaming machine so as to surround the predetermined electrical component in at least the closed state, and at least the closed state A partition portion (rib 512) that is disposed between the back side of the game board and the board box and has a plurality of walls that partition the gap between the back side of the game board and the board box; Comprising at least one of the attachment means and the substrate box,
A gaming machine configured to be maintained in a state in which the electrical component is covered by setting the substrate box in the closed state to be held by the holding unit,
The connecting pedestal member and the board box have a shape in which the attaching / detaching direction of each is regulated in a predetermined direction (a direction orthogonal to the rotation direction of the axis of the connecting pedestal member), and the positions of each other in the restricted state The board box is connected to the connecting base member and the board box in the attached state without leaving any traces in the mounting state by changing a predetermined amount. Linked pedestal sealing parts (435, 436) connected by a sealing member (breaking screw K) in a state where it cannot be moved away from the pedestal member are provided,
The holding portion is provided in a region that is in the covering state in the closed state, and the substrate box attached to the connection base member is rotated from the open state to the closed state. Accordingly, the substrate box is received and held, and in the holding state, the rotation of the substrate box in the direction to be in the open state is restricted and the movement in the direction to be in the detached state is allowed. And
The substrate box is moved in the disengagement direction by a specific amount shorter than the predetermined amount (the amount of movement from the state where the hook 508 and the recess 205A are engaged until the engagement protrusion 205 contacts the recess 507). The holding state by the holding unit is released, and the substrate box is configured to be rotatable in the direction of the open state.

(Partial modification of the elastic engagement mechanism 506)
48 and 49, the elastic engagement mechanism 506 is constituted by a holding piece 508A urged by a spring 509A in place of the synthetic resin support member 509. Also good.
That is, instead of the elasticity of the synthetic resin material, the holding piece 508A is brought into contact with the inclined surface of the conical engaging protrusion 205A protruding from the lower surface of the substrate box 201A, for example, by deformation of the spring 509A. Is moved backward and then moved forward and restored to engage with the shaft portion 205B of the engaging projection 205A, and both of the shaft portions 205B and the engaging projection 205A are brought into a state where they cannot be pulled out by the radial step. Can be configured to be locked.
Of course, the engagement state is released in the same manner as in the above-described embodiment. By sliding the substrate box 201A, the shaft portion 205B and the engagement protrusion 205A are separated from the engagement protrusion 205A, and the substrate box This is performed by turning 201A upward.
As described above, when the spring 509A is used as the elastic engagement mechanism 506, a stable strong urging force can be obtained, and a stable engagement and holding state can be obtained without deterioration of the material.

  In recent years, not only illegal acts on the main board case 53 as described in the above-mentioned document (Japanese Patent Application Laid-Open No. 2004-033603), but also electric parts such as relay boards attached to a ball assembly board are processed or illegal boards are used. It is also preferable to take measures against these since it is assumed that fraudulent acts such as changing the connection of wiring by installing a cable. Therefore, by covering the electrical component with another member (for example, a spacer in which a plurality of ribs are formed in a lattice shape) so that the separate member (for example, the spacer) cannot be removed, It is conceivable that separate parts (for example, spacers) are unitized. However, in this case, it may be difficult to attach the ball assembly board to the game board (screwing, etc.) that can be easily performed if it is a single unit due to unitization. In this case, the arrangement of the ball assembly plates that should guide the game balls that have entered the winning opening etc. on the back side of the game board is not stable, and there is a possibility that the game will be affected by causing clogging of the balls.

Therefore, in the present invention, the ball assembly board 460 is provided on the back surface of the game board 30, and the ball assembly board 460 discharges the game balls that have entered the winning opening to the lower side of the game board 30 on the game board 30 back side. A connecting base member 430 that supports the board box 201A is rotatably provided. The board box 201A is attached to the connecting base member 430, and the board box 201A is a game. As a gaming machine that is openable and closable in a covering state that covers the back surface of the board 30 and an exposed state that is exposed, the gaming machine has the following configuration.
That is, a first spacer 501 is interposed between the sphere assembly plate 460 and the substrate box 201A, and the first spacer 501 is screwed from the front side of the sphere assembly plate 460 and is engaged at both ends. And a mounting portion 478 for engaging the protruding piece (480B) at one end of the locking member 480 is provided on the front side of the spherical assembly plate 460. Are provided at two positions (at least one each) at positions near the both ends of the ball assembly plate and covered by the first spacer 501 on the back surface side of the ball assembly plate 460, and at the other end of the locking member 480. Fitting portions 481 for engaging the projecting pieces (480A) are provided at corresponding positions on the back surface of the game board 30, and the ball assembly plate 460 is connected to the first spacer 501 by the locking member 480. It is configured to be fitted and fixed to the game board 30 to.

Accordingly, the first spacer 501 is screwed from the front side of the ball assembly plate 460 by the above configuration, so that the first spacer 501 and the ball assembly plate 460 are integrated into a unit. As a result, it is possible to unify the mounting operation to the game board together with the electric parts such as the relay board laid on the ball assembly board 460.
At this time, since the screwing is performed from the front side of the ball assembly plate 460, once the unitized ball assembly plate 460 and the first spacer 501 are attached to the game board 30, the screwing is performed as follows. The game board 30 and the ball assembly board 460 are sandwiched and covered, and there is no possibility of being removed from the outside, thereby preventing fraud.
The unitized ball assembly board 460 and the first spacer 501 are attached to the game board 30 by a locking member 480 by fitting and fixing to both the ball assembly board 460 and the game board 30. As a result, the assembling work can be easily performed.

In addition, the gaming machine of the conventional configuration covers various electrical components laid on the back surface of the game board and the ball assembly plate provided here by making the board box openable and closable with respect to the back surface of the game board, The fraud is prevented by making it impossible to attack the electrical parts easily from the outside.
However, in the gaming machine having such a configuration, a space is formed between the game board (ball assembly board) and the board box. ) To facilitate fraud against the electrical components on the back.
In order to solve this problem, a spacer (intermediate member) is interposed between the game board (ball assembly board) and the board box so as to fill the space.

By the way, a signal from the control board is transmitted to a predetermined electrical component such as a big winning device or a variable winning device, or a predetermined electrical component such as a start opening detection is detected on the ball assembly plate provided on the back of the game board. A relay board for transmitting a signal from the sensor to the control board is provided. Specifically, a relay board mounting base is provided, and the relay board may be laid here.
The relay board is connected by a harness to which a connector is connected so that the connection between the board box and the electrical component can be disconnected so that the board box can be opened and closed as necessary for periodic inspection of the board box. .

Therefore, in order to connect such a harness to the connector on the board box side, the whole of the ball assembly plate cannot be simply covered with the spacer. Therefore, the spacer is a relay board. Specifically, the spacer is configured to have a unique shape that bypasses the relay substrate portion.
Even if the substrate box is covered by opening and closing the spacer having such a shape, there is a space between the substrate box and the spacer having a shape bypassing the relay substrate. There is an extremely high risk that fraud will occur.

  Therefore, in the present invention, the ball assembly board 460 is provided on the back surface of the game board 30, and the ball assembly board 460 discharges the game balls that have entered the winning opening to the lower side of the game board 30 on the game board 30 back side. A connecting base member 430 that supports the board box 201A is rotatably provided. The board box 201A is attached to the connecting base member 430, and the board box 201A is a game. As a gaming machine that is openable and closable in a covering state that covers the back surface of the board 30 and an exposed state that is exposed, the following configuration is provided.

That is, the ball assembly plate 460 is provided with a relay board mounting base 471 provided with a relay board 470 as one electrical component, and the ball assembly plate 460 covers the other electrical components provided in the ball assembly plate 460. A first spacer 501 is interposed between the collective plate 460 and the substrate box 201A, and at least the upper surface of the relay substrate mounting base 471 (the upper surface of the relay substrate 470) is attached to the back wall of the first spacer 501. A back surface opening 511 (important notch) is provided so as not to cover, and the back surface opening 511 is substantially entirely covered with the front surface of the board box 201A in a state where the substrate box 201A covers the back surface of the game board 30. Is inserted to close the back surface opening 511 and cover the relay substrate 470, and a second spacer 88 (also referred to as a relay substrate covering body) is provided in a protruding manner. To have.
As electrical components related to the relay board 470 laid on the ball assembly board 460, a game entered in a winning device (including a start winning device / variable winning device) and a winning port (including a starting port / large winning port) For example, a switch for detecting a sphere, a blade for opening / closing a winning opening, a driving device for driving a door, and the like.

With this configuration, the space for the relay board 470 of the harness 501 with respect to the relay board 470 of the ball assembly plate 460 is substantially reduced from the outside by the second spacer 88 in the closed body with respect to the back of the game board of the board box 201A. Thus, the relay board 470 can be prevented from being illegal.
In other words, when the first spacer 501 covers the ball assembly plate 460, the first spacer 501 is connected to the relay board mounting base 471 (the relay board 470 as one electric component) as before. Provided with a space that allows the harness to be attached / detached while being configured to be attachable / detachable to the harness. In addition, since it can be isolated from the outside by being occupied by the second spacer 88, it is possible to prevent an illegal attack from the outside with respect to the relay board 470 when the board box 201A covers the back surface of the gaming machine. It can be done. In other words, the relay box 470 can be maintained and inspected by rotating the board box 201A away from the back of the gaming machine, and other electrical components can be maintained and inspected without removing the ball assembly plate 460. Not to be.

The second spacer 88 is formed by projecting a plurality of partition walls partitioned by a predetermined area from the front surface of the substrate box, and the partition walls have spaces.
As described above, the second spacer protrudes from the front surface of the substrate box, and is divided into a plurality of partition walls (that is, the horizontal wall portion 88A and the vertical wall portion 88B) which are partitioned in a predetermined area. The connectors and harnesses connected to the relay board 470 covered by the second spacer by configuring the partition walls (the horizontal wall portion 88A and the vertical wall portion 88B) to have spaces. The space occupied by the second spacer 88 can be secured and the weight of the second spacer 88 can be reduced to reduce the amount of molding material.

In addition, the partition wall (the horizontal wall portion 88A and the vertical wall portion 88B) of the second spacer 88 has a part corresponding to the relay substrate mounting base 471 and a small projecting length. A harness extraction space between the mounting base 471 and the partition wall (the horizontal wall portion 88A and the vertical wall portion 88B) is formed large.
Thus, by reducing the protruding length of part of the partition walls (the horizontal wall portion 88A and the vertical wall portion 88B) of the second spacer 88, the harness take-out space is locally increased, and a large connector and The relay substrate 470 can be covered without difficulty while the harness is not pressed.

Further, the side walls 502 of the first spacers 501 that form the side openings 511A are formed in a plurality of partition walls (lateral wall portions 88A and vertical wall portions 88B) of the bulging portion 89 of the second spacer 88. A plurality of horizontal wall portions 88A provided at predetermined intervals so as to cross the upper edge portion at right angles are included, and an outer end portion of each horizontal wall portion 88A is an outer vertical wall portion 88B of the partition wall. Are connected by.
As described above, the bulging portion 89 is also constituted by partition walls (the horizontal wall portion 88A and the vertical wall portion 88B) in order to reduce weight and weight, but the partition walls (the horizontal wall portion 88A and the vertical wall portion 88B). In addition, by including a plurality of lateral wall portions 88A crossing the upper edge of the side wall 502 of the first spacer 501 orthogonally, the side opening 511A can be divided into a plurality of in the longitudinal direction, As a result, in the side opening 511A that remains long, the unauthorized operation of the unauthorized tool is possible in the longitudinal direction. However, by subdividing, the freedom of such unauthorized operation is limited and it is difficult to perform the unauthorized operation. It can be done.
Further, since the outer end portions of the plurality of horizontal wall portions 88A are connected by the vertical wall portion 88B of the partition wall, when attempting to perform an unauthorized attack on the side surface opening portion 511A from the lateral outer side. The vertical wall portion 88B obstructs the intrusion of wires, jigs, etc., and cannot be easily invaded.

Further, the partition walls (the horizontal wall portion 88A and the vertical wall portion 88B) of the second spacer 88 are close to the upper edge of the side wall 502 of the first spacer 501 that forms the side opening 511A. A vertical wall 88B extending along the upper edge of the side wall 502 is included.
Thus, the second spacer 88 is constituted by a partition wall composed of a plurality of horizontal wall portions 88A and vertical wall portions 88B in order to reduce weight and weight, and the vertical wall portion 88B is formed by the side opening. Since the first spacer 501 forming the portion 511A is configured to be close to the upper edge of the side wall 502 and extend along the upper edge of the side wall 502, the wire or the illegal jig may be outside. Even when the vertical wall portion 88B is allowed to enter underneath and exceeds the upper edge portion of the side wall 502 of the second spacer 88, the vertical wall portion 88B extends along the upper edge portion of the side wall 502. It is easy to prevent entry into the interior.

(Function)
With the above configuration, the first spacer 501 between the ball assembly plate 460 and the substrate box 201A fills the space between the two, making it difficult for unauthorized intervention from both. Since the holding portion 505 is provided in a portion of the first spacer 501 that is covered with the substrate box 201A when the substrate box 201A is in the covered state, it is easy to hold the covered state of the substrate box 201A. Thus, the board box 201A is rotated to release the covering state, thereby preventing unauthorized operation of the electrical components on the back side of the game board 30.
Furthermore, if necessary, the substrate box 201A is slid relative to the connection base member 430 by releasing the sealing of the connection base sealing portion 430A between the board box 201A and the connection base member 430. Thus, the holding state of the holding portion 505 is released to release the covering state of the substrate box 201A, and at the same time, the substrate box 201A can be detached from the connecting base member 430.

  Further, when the board box 201A and the connection base member 430 are slidably engaged, and the seal of the connection base sealing part 430A is released and slid within the predetermined range, the holding part 505 Since the holding state is released and the substrate box 201A can be shifted to the exposed state together with the connection base member 430, the substrate box 201A and the connection base member 430 are released by releasing the sealing of the connection base sealing portion 430A. The holding state of the holding portion 505 (the covering state of the substrate box 201A) can be released using a sliding operation for releasing the connection to the substrate box 201A. Thus, a series of releasing operations is performed to release the covering state of the substrate box 201A. It can be used for both purposes.

  Furthermore, the holding part 505 is configured such that the direction in which the board box 201A is removed from the connection base member 430 and the sliding direction (displacement direction) of the board box 201A that releases the holding state of the holding part 505 are the same. The operation for both releasing the sealing of the connecting base sealing portion 430A and releasing the holding state of the holding portion 505 without requiring a configuration for obtaining a specific direction operation of the substrate box 201A for releasing the holding Can be one.

  Further, the holding portion 505 includes an elastic engagement mechanism 506, and the engagement protrusion 205 provided on the back surface of the substrate box 201A is elasticized by the elastic engagement mechanism 506 as the substrate box 201A rotates to the covering state. Since the engagement protrusion 205 is configured to be engaged so as not to be disengaged by being engaged by the displacement, the retaining state of the retaining portion 505 that cannot be disengaged only by the rotation of the substrate box 201A. It can be obtained.

  Further, since the holding portion 505 is provided in the first spacer 501 at a position opposite to the rotatable connection portion of the connection base member 430, the board box 201A can be connected to one side. It can be fixed in a stable state by being fixed on both sides of the base member 430 and the holding portion 505 on the other side.

  Furthermore, the first spacer 501 fills the space between the ball assembly plate 460 and the substrate box 201A. Further, the peripheral wall 502 and the peripheral wall 462 of the ball assembly plate 460 correspond to each other. In this way, the space between the two can be partitioned by their peripheral walls and can be isolated from the outside, so that the ball assembly plate 460 and the substrate box 201A can be further separated. It is possible to secure the occupation of the space between them and prevent illegal attacks on the inside.

  In addition, the fitting rib 512A that contacts the inner periphery of the peripheral wall 462 of the ball assembly plate 460 is extended longer than the peripheral wall 502 inside the peripheral wall 502 of the first spacer 501. When the first spacer 501 is aligned with the ball assembly plate 460, the fitting rib 512A is positioned while serving as a guide, and the abutting state of both can be obtained smoothly and the fitting rib 512A This also contributes to increasing the strength of the peripheral wall 502 of the first spacer 501.

  Furthermore, by providing at least two pairs of fitting members and fitted members on the ball assembly plate 460 and the first spacer 501, the positioning of the both can be performed easily and the fitted members and the fitted members. Since both are screwed from the back side of the ball assembly plate 460, the first spacer 501 is screwed and then the ball assembly plate 460 is attached to the back surface of the game board 30 once. The spacer 501 cannot remove the screw from the outside, and can contribute to prevention of fraud by removing the first spacer 501.

Other main actions will be described.
Since the gaming machine according to the present invention is configured as described above, the first spacer 501 that covers the ball assembly plate 460 is adopted while adopting the conventional method of attaching / detaching the harness to / from the relay board 470 of the ball assembly plate 460. The space for the relay board is closed from the outside by the second spacer 88 in the closed body with respect to the back side of the game board of the board box 201A, so that fraud to the relay board 470 can be prevented.
That is, when the first spacer 501 covers the ball assembly plate 460, the first spacer 501 is configured so as not to cover the relay board mounting base 471 (the relay board 470) as before. In addition, while allowing the harness to be attached / detached, the space enabling the attachment / detachment of the harness can be isolated from the outside by being occupied by the second spacer 88 provided on the front surface of the board box 201A. In the state where the board box 201A covers the back side of the game board, it is possible to prevent an unauthorized attack from the outside on the relay board 470.

  And as usual, the harness take-out space 511S is present and the harness can be easily attached and detached as necessary, but the space 511S is occupied by the second spacer 88 at the top, but the first spacer 501 The harness take-out passage 511P formed in the side wall 502 communicates with the outside, and the harness take-out passage 511P is blocked by the hook 84 in a side view, so that the harness take-out space 511S is substantially upward and lateral. In other words, a state of being blocked and sealed from the outside can be obtained, and an unauthorized attack to the relay board 470 through the harness take-out space 511S can be prevented.

  Further, the side wall 502 of the first spacer 501 does not have a simple structure in which the side wall 502 of the first spacer 501 is in direct contact with the bottom surface of the board box 201A at the location where the harness take-out passage 511P is formed. In addition, since the bulging portion 89 that substantially occupies the side opening 511A and extends to the outside of the side wall 502 of the first spacer 501 is provided, the harness is removed from the side wall 502 of the first spacer 501. Since the passage 511P is located on the back side of the bulging portion 89, the bulging portion 89 becomes a hindrance when it is attempted to attack the harness take-out passage 511P from the outside in a side view. The side wall 502 of the first spacer 501 is the bottom of the substrate box 201A (inner case 85). If the simple structure is in direct contact with the inner side of the relay board 470 through the harness take-out passage 511P of the side wall 502, it is easy to perform fraud, and this unique structure more reliably prevents fraud. To get.

  Further, while the harness take-out passage 511P has a simple structure formed by cutting out the upper edge portion 502A of the side wall 502 of the first spacer 501 into a recess, the bottom portion 89A of the bulging portion 89 is Since the upper surface opening of the recess of the harness take-out passage 511P is closed in a substantially close state in a side view, even if an attempt is made to attack with a wire, jig or the like from the side, the bottom portion 89A of the bulging portion 89 prevents it. It is difficult to attack easily.

  Further, the second spacer 88 protrudes from the front surface of the substrate box. The second spacer 88 is composed of a plurality of partition walls partitioned by a predetermined area, and the partition walls have spaces. By doing so, it is possible to secure a space occupied by the connectors and harnesses connected to the relay board 470 covered by the second spacer 88 and reduce the weight of the configuration of the second spacer 88, thereby forming a molding material. Can be reduced.

  In addition, the partition wall of the second spacer 88 has a part corresponding to the relay board mounting base 471 and a small projecting length, so that the distance between the relay board mounting base 471 and the partition wall is small. Since the harness take-out space 511S is formed large, the harness take-out space 511S is locally enlarged, and the relay board 470 can be covered without difficulty in a state where the large connector and the harness are not compressed.

Further, the plurality of partition walls of the bulging portion 89 of the second spacer 88 cross the upper edge portion 502A of the side wall 502 of the first spacer 501 forming the side opening 511A perpendicularly. A plurality of horizontal wall portions 88A provided at predetermined intervals are included, and the outer end portions of the respective horizontal wall portions 88A are connected by the outer vertical wall portion 88B of the partition wall. The portion 89 is also constituted by a partition wall for light weight and weight reduction, and the partition wall includes a plurality of lateral wall portions 88A that orthogonally cross the upper edge portion 502A of the side wall 502 of the first spacer 501. Thus, the side opening 511A can be divided into a plurality of parts in the longitudinal direction. As a result, in the side opening 511A that remains long, the unauthorized tool can be freely operated in the longitudinal direction. However, Limits the flexibility of such manipulation by differentiation, it is possible to difficult to perform unauthorized.
Further, since the outer end portions of the plurality of horizontal wall portions 88A are connected by the vertical wall portion 88B of the partition wall, when attempting to perform an unauthorized attack on the side surface opening portion 511A from the lateral outer side. The vertical wall portion 88B obstructs the intrusion of wires, jigs, etc., and cannot be easily invaded.

  Further, the partition wall of the second spacer 88 is adjacent to the upper edge 502A of the side wall 502 of the first spacer 501 forming the side opening 511A, and the upper edge 502A of the side wall 502 is formed. In order to reduce the weight and weight, the second spacer 88 is constituted by a partition wall composed of a plurality of horizontal wall portions 88B and vertical wall portions 88B. However, the vertical wall 88B is adjacent to the upper edge 502A of the side wall 502 of the first spacer 501 forming the side opening 511A and extends along the upper edge 502A of the side wall 502. Even if a wire or an illegal tool penetrates the outer vertical wall 88B and penetrates the upper edge 502A of the side wall 502 of the first spacer 501, this side is used. Is the likely be prevented from entering the inside by the vertical wall portion 88B extending along the upper edge 502A of the wall 502.

  The present invention can be appropriately implemented in various forms of gaming machines as long as it is a gaming machine including a ball assembly board and a board box, and its application range is wide.
