Description

  The present invention relates to gaming machines represented by pachinko machines and slot machines.

  Such a gaming machine includes a board unit having a board box containing a control board for controlling a game inside, and the board unit is a sealing mechanism (usually a sealing portion sealed by a sealing member). There are a number of such), and there are traces left when trying to perform a fraudulent act such as ROM exchange by opening the board unit, and it is known that it is easy to detect that the fraud has been done. Yes.

  Further, by providing a plurality of the sealing members, these can be used individually, and a plurality of opening / closing operations (opening and sealing) are possible.

  Furthermore, in order to connect the harness from the outside to the connector of the control board accommodated in the board box, an opening is required in the board box. It is desirable to keep the size of the gap to a minimum by keeping the size corresponding to the shape of the connector as much as possible.

  For this reason, it is necessary to separately develop and manufacture board boxes for a plurality of types of control boards having different numbers and shapes of connectors.

  In order to solve such problems, conventionally, the board box is not provided with a portion corresponding to the connector, and a member (connector cover) having a connector opening is provided separately from the board box. A gaming machine including a board unit has been proposed.

In this way, even when the number and shape of connectors on the control boards of various gaming machines are different, there is no need to prepare board boxes of different shapes, and it can be handled by changing only the connector cover. Therefore, there is no extra effort or cost.
As for the gaming machine having such a configuration, for example, the following documents can be cited.

JP 2000-325628 A

  However, the conventional connector cover described above has been improved in that it is not necessary to prepare a board box corresponding to various gaming machines by being separated from the board box. It is considered as a member that fills the gap between the connector and does not have a structure that gives sufficient strength. Therefore, by forcibly deforming the connector cover, a gap is formed. There was a risk of fraud with the connector.

In addition, even when the opening provided in the connector cover is stopped to a size corresponding to the shape of the connector, the connection location is exposed to the outside of the board box, so that a certain harness is connected to the control board. Connector, for example, a connector that connects the ball detection sensor and the control board, sends an illegal signal to the board by interposing another part, and performs an illegal operation (such as awarding a prize ball even if no prize is received) There remains the risk of fraud, such as letting it happen. Therefore, it is originally desirable that various harnesses are connected to the control board and then housed in the board box including the connection portion, and the board box is sealed in that state.
However, since the connection of various harnesses is usually made near the completion of the gaming machine, if the board box is not sealed until that time, the risk of fraud such as ROM replacement increases, The anti-fraud property of the control board body is reduced.

Therefore, first, it was considered to provide a connection portion cover that covers the connection window portion that performs connector connection. And it was thought that this connection part cover should just be able to be sealed separately from sealing of the case of a board | substrate unit.
Also, when closing the connecting part cover, the harness extending from the connector should not be caught between the connecting part cover and the side wall of the case so that it can be led out from the connecting part cover. I thought about how to do this.

  The present invention has been devised in view of such problems, and after connecting the connector without sealing the substrate case in the manufacturing stage and reducing the anti-fraud property to the inside, the connecting window portion In order to prevent unauthorized attacks from the connection window portion of the connector of the board unit, and to provide a necessary connection portion cover for that purpose, a harness extending from the connector is provided. It is an object of the present invention to be able to lead out to the outside without being caught between the connection portion cover and the side wall of the case when the connection portion cover is closed.

A fourth sealing portion corresponding to the third sealing portion,
In the closed state of the connection part cover, the third sealing part and the fourth sealing part are connected using a second sealing member, and the third sealing part and the fourth sealing part are connected by the sealing member. When it is connected to a stop portion, when opening and closing the connection portion cover, it is necessary to destroy the connection portion cover or to cut a predetermined part,
The connection portion cover has a front plate portion;
In the front plate portion, at least one recess for taking out the harness of the connector is provided in a state of entering the support portion side from the side far from the support portion of the front plate portion,
A harness hook is provided integrally with the connection portion cover in the vicinity of the recess.
It is characterized by that.

According to the present invention, the board case is sealed in the manufacturing stage, and the connection window cover is used to cover and seal the connection window using the connection cover after the connector is connected without reducing the anti-fraud property to the inside. Therefore, it is possible to prevent unauthorized attack from the connection window portion of the connector of the board unit and to prevent the harness from the connector and the connection portion cover when closing the connection window portion by the connection portion cover. There exists an advantage which can be closed and sealed in the state which does not have a possibility of pinching | interposing between the side walls of a 1st case.

In the present invention, the following vocabulary is clarified.
The first case and the second case are distinguished from each other in terms of designation, and it is used as appropriate to indicate which of the main body part that accommodates the control board or the lid part thereof. The main body portion that accommodates is referred to as a first case.

  The connection window portion of the first case is an opening for connecting to the outside by connector connection. This outside includes a connection to another member in the board unit, and also includes a connection to the outside of the board unit.

  Moreover, the window part wall body which forms the said window part for a connection of a 1st case means the wall body of the vicinity which forms a window part regardless of the shape.

  The third case covers the connection window, and the embodiment is not a case-like (container for container) (although it has a U-shaped inner wall), the first case The third case is given a name separate from the case and the second case.

  Furthermore, the third case covering the connection window portion of the first case in a close contact state means, for example, a predetermined portion (main body) that surrounds the outside of the connector opening provided in the main body portion of the third case. The predetermined part of the part) and the corresponding predetermined part of the first case are in close contact with each other.

  The connector opening of the third case is an opening for positioning a connector connected to the control board.

  The part of the peripheral part of the main body part covering the connector opening of the third case refers to at least one of the four sides or a part of one side when the main body part is rectangular in a front view.

  Furthermore, the sealed state means a state in which the trace always remains when the state is released. Therefore, even though it is physically easy to release the sealed state, it is impossible or extremely difficult to release the sealed state without being known to the administrator. If the stop state is released without authority and some kind of work is performed on the control board or the like, the fact can be easily known by the administrator.

The gaming machine according to the present invention has as means 1,
A substrate unit having a first case and a second case and having a control board provided therein, a first sealing portion provided on the first case side, and a second provided on the second case side A first sealing member that connects the sealing portion and the first sealing portion and the second sealing portion, and the first sealing portion and the second sealing portion by the sealing member; A connector that is connected to the control board in the first case, and includes a board unit that needs to break the board unit or to cut a predetermined part when the control board is taken out. In a gaming machine provided with a connection window for
A support part for supporting the connection part cover made of synthetic resin to be openable and closable on the first case so as to cover the connection window part in a state in which the harness of the connector is led out to the outside;
A third sealing portion provided on the connection portion cover;
A fourth sealing portion corresponding to the third sealing portion,
In the closed state of the connection part cover, the third sealing part and the fourth sealing part are connected using a second sealing member, and the third sealing part and the fourth sealing part are connected by the sealing member. When it is connected to a stop portion, when opening and closing the connection portion cover, it is necessary to destroy the connection portion cover or to cut a predetermined part,
The connection portion cover has a front plate portion;
In the front plate portion, at least one recess for taking out the harness of the connector is provided in a state of entering the support portion side from the side far from the support portion of the front plate portion,
A harness hook is provided integrally with the connection portion cover in the vicinity of the recess.
It is characterized by that.

  As described above, the first sealing portion and the second sealing portion that join the first case and the second case forming the substrate unit for housing the control substrate in a sealed state, and various harnesses on the control substrate. Control in the manufacturing stage by separately providing the third sealing portion and the fourth sealing portion for fixing the connection portion cover for covering the connection window portion of the first case for connecting in a sealed state. Unauthorized acts on the board are prevented by the first sealing part and the second sealing part, and the connection part between the control board and a harness of a certain type, for example, the ball detection sensor harness arranged at the winning hole of the game ball is illegal. It is possible to prevent an illegal act that causes the control board to operate illegally by interposing various parts. That is, in order to prevent fraud with respect to the connection location, the connection window portion is abolished, various harnesses are connected to the control board, and the control board is housed inside the board unit so that it cannot be accessed from the outside. It is originally desirable that the sealing is performed. However, since various harnesses are usually connected near the completion of the gaming machine, if the board unit is not sealed until that time, there is a risk that fraud such as ROM replacement will be performed by that time. Will increase. That is, the anti-fraud property at the manufacturing stage of the gaming machine is reduced. Therefore, by providing the third sealing portion and the fourth sealing portion, which are different from the substrate case, in the connection portion cover that covers the connection portion, the control substrate body has an early manufacturing stage. It becomes possible to store in the board unit in a sealed state at the time, thereby preventing illegal acts on the control board at the manufacturing stage (before connector connection), and also after connecting the control board and various harnesses It is possible to prevent fraudulent acts on the connection points.

Moreover, although the said connection part cover is a separate component from a 1st case and a 2nd case, when connecting various harnesses to a control board by having provided the connection part cover in the 1st case so that opening and closing was possible. There is no need to remove or attach the board unit from the board unit simply by leaving the connection part cover open, and there is no fear of losing the connection part cover, and the harness connection work is simplified.
In particular, the connection portion cover has a front plate portion, and the front plate portion is provided with at least one recess for taking out the harness of the connector from the side far from the support portion of the front plate portion. When closing the connection portion cover, the harness extending from the connector is removed when the connection portion cover is closed by providing the harness hook integrally with the connection portion cover. The harness is sandwiched between the front plate portion and the side wall of the first case, and there are many possibilities of disconnection. The harness hook keeps the harness away from the lower end edge of the front plate portion and is located in the middle of the recess. Therefore, the harness can be prevented from being caught when the connecting portion cover is closed, and the occurrence of the pinching can be avoided in advance.
In addition, it is possible to avoid the possibility that the completely closed state of the connection portion cover cannot be obtained due to the sandwiching of the harness.

FIG. 4 is a perspective view showing a state in which the inner frame 12, the front frame set 14, and the set plate 400 are opened with respect to the outer frame 11. (However, in FIG. 4, for the sake of convenience, the configuration in the game castle on the surface of the game board 30 (nail, center accessory, etc.) is shown blank, but the out port 36 is drawn).

  As shown in FIGS. 1 to 4, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be openable and closable. I have. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of light metal such as resin or aluminum in order to reduce the weight.

  The opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side of the game ball launching handle 18 (left side of the pachinko machine 10 in FIG. 1) as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the axis as the center. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  When roughly classified, the front frame set 14 includes a ball tray portion provided at the lowermost portion thereof, and a window frame portion formed in a range above the ball tray portion. The ball tray portion is fixed to a lower portion of the front frame set 14 with a fastener such as a screw. A lower plate 15, a ball release lever 17, a game ball launch handle 18, and an ashtray 22 are provided on the front side of the ball tray portion. The lower tray 15 serving as a ball tray serves to stop 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 launcher 38 includes a game ball launch handle 18, a set handle, a launch solenoid, and the like, which will be described later.

  The sound output port 24 is an output port for outputting sound from a speaker (not shown) provided at the position of the upper left and right ends of the front frame set 14. Moreover, the ashtray 22 is provided on the left side of the lower tray 15 as shown in FIG. The ashtray 22 is supported so as to rotate (for example, forwardly toward the front side) about an axis line in the left-right direction (horizontal direction).

  Note that most of the front frame set 14 is formed of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are molded from flame-retardant ABS resin. For this reason, this part is hard to burn.

  As shown in FIG. 4, the front frame set 14 is attached to the inner frame 12 so that it can be opened and closed. Like the inner frame 12, the front frame set 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 to the front side with an axial center. Moreover, the front frame set 14 is attached so as to fit into the outer wall (rib) 12 b of the inner frame 12.

  That is, since the front frame set 14 is attached so that at least a part (the entire circumference in this embodiment) of the front frame set 14 fits into the outer wall (rib) 12b of the inner frame 12, the inner frame 12 and the front frame It is possible to prevent an illegal act such as inserting a foreign object (such as a needle shape or a thin plate shape, specifically, a wire, a piano wire, a celluloid plate, etc.) from the gap with the frame set 14.

  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 set 14 at a position above the lower plate 15 in the ball receiving portion of the front frame set 14. The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

As shown in FIG. 4, the inner frame 12 is mainly configured by a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20.
A game board 30 shown in FIGS. 4 and 5 is detachably mounted on the rear side of the resin base 20. As shown in FIG. 5, the game board 30 is made of a rectangular plywood, one upper corner is shouldered (described later), and its peripheral edge abuts on the back side of the resin base 20 (inner frame 12). It has been installed in the state.

  Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20 (FIG. 4 shows an out port 36 of the game board 30). ing). And here, a corner (corner) close to a pivoting portion of the game board 30 with respect to the outer frame 11 of the inner frame 12 (a pivoting centering on an opening / closing axis extending vertically to the left side when viewed from the front of the pachinko machine 10). However, as shown in FIG. 5, the corner is dropped (notched) 720 in a substantially triangular shape.

  Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 5 is a front view showing the configuration of the game board 30. Two pairs of general prize-winning ports 31 and 31 are positioned in a stepped manner at a slightly lower position on the left and right of the game board 30, and a starting hole 33 is disposed at the lower center of the game board 30. However, these sensors are provided on the back surface of the game board 30 and these sensors are connected to a main control board 80 (main control device) to be described later through an electric harness (not shown).

  When a game ball enters the general winning ports 31, 31 and the start port 33, it is detected by the detection sensors, and the upper plate 19 (or the lower plate 15) is detected based on the output of the detection sensors. 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 80, which will be described later, and a payout command (the number of game balls to be paid out) corresponding to the winning situation each time is sent from the main control board 80. It 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.

  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 provided with the general winning ports 31, 31 is provided at the left and right lower positions of the game board 30, and an out port 36 is provided at the lower part of the game board 30 for various winnings. A game ball that has not entered the apparatus or the like is guided through the out port 36 toward a ball discharge path (not shown) on the back of the game board 30. Further, the game board 30 is provided with a large number of guide nails for appropriately dispersing and adjusting the falling direction of the game balls, and a windmill having the same function.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. .

  In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of a game ball. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51.

  In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 5). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 5: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner 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. 5) such as certificate stamps (for example, serial numbers are described) and plates. In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 5) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said.

  Therefore, when it is referred to as a game area, the guide rail portion is not included, and the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. 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 21 (game board 30), a launch rail for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. The launch rail is fixedly attached to the resin base via a metal plate behind the launch rail, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, 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 set 14 side (the 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 shot with the slide movement of the ball striking ball along the shaft portion.

  A reference numeral 67 in FIG. 4 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / closable shutter that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction. The front frame set 14 is opened from the inner frame 12. In the performance (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 set 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 set 14 to be in a substantially horizontal state. The game balls discharged to the right pass through the ball passage rod 69 and are discharged to the upper plate 19 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game balls in the payout passage and the like spill out of the pachinko machine 10 when the front frame set 14 is opened.

As shown in FIG. 4, a front frame set open detection switch 13 that detects that the front frame set 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 set 14 is opened, it is output from the front frame set open detection switch 13 to the computer for the hall (in the pachinko shop). Further, when the front frame set 14 is closed, the metal reinforcing plate of the front frame set 14 comes into contact with the pair of metal fittings of the inner frame 12, and the grounding of the front frame set 14 is ensured. .
As shown in FIG. 4, the corner of the game board 30 close to the pivoting portion 725 with respect to the outer frame 11 of the inner frame 12 is substantially triangular as shown in FIG. ) Is 720. As shown in FIG. 4, the pivoting portion 725 is constructed by pivotally attaching a mounting bracket fixed to the inner frame 12 to a bracket 726 (upper end portion) (lower end portion is not shown) fixed to the outer frame 11. Has been.

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

  The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized 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 set 14 is provided with light emitting portions 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 electrical decoration unit 102 having a light emitting unit such as an LED is provided symmetrically, and the LED is also located at the center of the electrical decoration unit 102 and at the top of the pachinko machine 10. A central illumination unit 103 having a built-in light emitting unit is provided.

In order to provide the receiving portions 508 of the receiving portions 508, 508, a notch that is cut out in a U shape inwardly by an amount corresponding to about 1/2 of the thickness of the claw portion 507 is formed on the side wall end surface of the cover body 500. A notch groove 508a is formed, has a U-shaped groove 508b that is continuous with the notch groove 508a, and a receiving portion 508 having a bottomed rectangular cylindrical body has a tip 508c. The lid body 500 is integrally formed with the side end portion. The U-shaped groove 508 b is continuous with a reverse U-shaped groove e on the tip side of the receiving portion 508 of the rectangular cylindrical body. This inverted U-shaped groove e has a shape as viewed from the outside of the lid body portion 500 (when a cross section in a direction perpendicular to the longitudinal direction of the receiving portion 508 of the rectangular cylindrical body is seen, Character).

  The bottom surface of the receiving portion 508 of the rectangular cylindrical body, that is, the wall portion facing the case main body 400 is cut away to form an opening 508d. The opening 508d is for receiving a hook-shaped hook 507a at the tip of the claw 507 that has entered the receiving portion 508 of the rectangular tubular body. Further, when the engagement between the claw portion 507 and the receiving portion 508 is to be released, a tool is inserted through the opening portion 508d, the claw portion 507 is elastically deformed, and the hook 507a is lifted from the opening portion 508d. It is used to make a match.

(Description of the action of the engaging portion 506)
The operation of the engaging portion 506 will be described. In the state shown in FIG. 14, the case main body portion 400 and the lid body portion 500 are face-matched by fitting the engaging groove 411 and the fitting protrusion 511. This is the state immediately before the slide fit between the two. FIG. 15 is a vertical side view taken along the line AA in FIG. 14 in this state, and the claw portion 507 is slid in the left direction in the drawing and moved.

In FIG. 16, the claw portion 507 reaches the receiving portion 508, and the hook 507a of the claw portion 507 rides on the bottom of the inner U-shape of the rectangular cylindrical receiving portion 508, and starts elastic deformation. FIG. 24 is a longitudinal sectional side view taken along the line BB in FIG. 23 in this state, and the slide further proceeds from here.
18 shows a state in which the slide fitting between the case main body 400 and the lid body 500 has been completed, and FIG. 19 is a longitudinal sectional side view taken along the line CC in FIG. The hook 507a reaches the opening 508d of the receiving portion 508 and falls into the opening 508d by the elastic restoring force. As a result, the case body 400 and the lid 500 are engaged in the sliding direction and cannot be released in the opening direction. In this state, the main body side sealing portion 401 and the lid body side sealing portion 501 are fixed by the sealing pins 700.

After this, when the fraudster tried to open the base unit 201 by destroying the main body side sealing portion 401 and the lid side sealing portion 501, it was conventionally possible to open the base unit 201 only by destroying it. Since the plurality of (three or four) engaging portions 506 are engaged, they cannot be opened unless they are released or destroyed, and this requires much time and effort. It becomes.
In addition, since a plurality of engaging portions 506 are provided, it is necessary to find out where they exist, which also requires time and effort. It is possible to prevent fraud in time.

The inner wall 93 of the third case 90 is further extended as the identification information display part 95 so that the inside immediately after passing through the overlapping part. It is not possible to pass between the two easily.

  Further, the first case 70 is provided with a box-shaped CPU chip storage portion 74 for protecting an important CPU chip from unauthorized intrusion, but the identification information display portion 95 is The illegal intrusion from the connection window 72 side of the first case 70 is provided at a position corresponding to the CPU chip storage portion 74 and the connection degree portion 72 and extends toward the CPU chip storage portion 74. (Foreign matter enters between the inner wall body 93 of the third case 90 and the wall body of the first case 70) In contrast, even if a wire or the like tries to reach the CPU chip storage portion 74, the identification is performed during this period. The information display unit 95 gets in the way and cannot reach the required position of the CPU chip storage unit 74, and can only reach the base of the CPU chip storage unit 74 (joint portion with the wall surface of the first case 70). Is It is possible to protect against CPU chip made more reliable.

  Furthermore, on the U-shaped opening side of the main body 92 of the third case 90, the inner wall 93 of the main body 92 of the third case 90 and the end surface 73a of the window wall 73 of the first case 70 are left as they are. The first case 70 is provided with a receiving surface 75 where the contact with the outer surface 92a of the main body 92 of the third case 90 is received. As a result, the main body 92 of the third case 90 can be reliably brought into contact with and adhered to the entire circumference of the window wall 73 of the first case 70.

  Further, a substrate receiving surface 76 for fitting and laying the main control substrate 80 is formed on the inner side surface of the first case 70, but the opening of the window wall 73 of the first case 70 is used. Therefore, it is possible to prevent the main control board 80 from being floated only in this portion and to improve the fit of the main control board 80 as a whole.

  And the said protrusion 97 will also function as a rib of the main-body part 92 of the 3rd case 90 simultaneously, and will raise the intensity | strength of the 3rd case 90. FIG.

  Further, the main control board 80 is fixed to the first case 70, and the outer edge 92 b of the third case 90 is pressed toward the first case 70 by the edge of the main control board 80 to be in close contact with the receiving part 75. As a result, it is possible to apply more pressure to the contact state between the third case and the first case, and even if trying to intrude foreign matter, a gap is not easily formed at the joint between the two cases. Can do.

Further, a connector opening 91 exists in the main body 92 of the third case 90. If this opening is a simple opening, the inserted connector 99 is almost entirely exposed to the outside. If other objects come into contact with each other, the connector is likely to be deformed or poorly joined, but the connector 99 can be protected by erecting the protective wall 96 as described above, and in this way from the main body 92. There is also an advantage that the strength of the main body 92 can be increased by erecting the protective wall 96.
Further, the fitting of the groove 41 of the first case 70 and the upper ends of the protrusions 93c and the inner side wall short side portion 93b (concave fitting) results in the window part wall 73 and the inner side wall in the connection window 72. Even if a foreign object is to enter through a gap with the body 93, further intrusion is prevented at the fitting portion, and it is possible to more completely prevent unauthorized work.

About harness hooks.
As described above, the harness hook 150 is formed in a substantially L shape in plan view, and one end thereof is configured as the free end portion 150b, so that the molding material can be easily elastically deformed, and the harness is attached to the free end portion 150b. A gap can be formed by lifting the free end 150b by the contact, and the harness can easily enter the recess 44.
In addition, since the harness hook 150 is formed of a plate-like body having a width from the entrance 44a side to the opposite side of the recess 44, the harness that has entered the recess 44 has an entrance to the recess 44 corresponding to the plate width. It is possible to move away from the portion 44a inward, that is, away from the lower end portion of the front plate portion 26b, and more reliably avoid pinching between the lower end portion and the side wall of the first case 70. be able to.
The concave portion 44 includes a linear slit in a thin groove state or a bent slit, a shape close to a substantially circular shape, a semicircular shape, or other shapes.

(Modification of harness hook)
As shown in FIG. 20, here, in the harness hook 150, the hook portions 150 </ b> A and 150 </ b> B have both end portions 44 b and 44 c of the entrance portion 44 a of the concave portion 44 as base end portions and are directed toward the center of the concave portion 44. The hook portions 150A and 150B are extended so as to be close to each other in a state of being opposed to each other, and allow the harness to enter the concave portion 44 from the outside by elastic deformation of the synthetic resin of the forming material, but can easily come out to the outside. Is configured to not.
Thus, the harness hook 150 is composed of two parts, and the hook part 150A.
, 150B is elastically deformed so that the harness enters the recess 44 from the opposite portion of each hook portion 150A, 150B at the center of the recess 44, so that the harness enters the recess 44 from a straight state. Therefore, it is not necessary to twist the harness sideways (bending or twisting in the case of an L-shaped structure such as the harness hook embodiment), and smooth insertion is possible.

Embodiment 2
Hereinafter, Embodiment 2 of the present invention will be described with reference to FIG. FIG. 12 is an exploded view of the first control board unit of the second embodiment.
As shown in FIG. 12, in the second embodiment, a fourth sealing portion 39 </ b> A that pairs with the third sealing portion 37 of the connection portion cover 26 and fixes the connection portion cover 26 in the closed position in a sealed state. However, while being provided on the mounting base 40 for mounting the first control board unit 201 to the back surface of the game board 30, the fourth sealing portion is removed from the second case 85A. In the second embodiment, the rest of the configuration is the same as that of the first embodiment, and a detailed description thereof will be omitted. The fourth sealing portion 39A is connected to the mounting base 40 with thin ribs 39b so that it can be easily separated from the mounting base 40 when sealing and unsealing are repeated.
In this way, by providing the fourth sealing portion 39A on the mounting base 40 for attaching the first control board unit 201 to the game board 30 instead of the second case 85A, the second case 85A constituting the board box is provided. The structure is simplified and the size can be reduced. As a result, handling of the first control board unit 201, which is often handled as an independent component or component at the manufacturing stage, is simplified, and the manufacturing process of the gaming machine is simplified.
Since the mounting base 40 is attached to the back surface of the game board 30, another support member to which the board unit is not attached is fixed to the back surface of the game board 30, and the fourth sealing portion 39A is attached to this support member. If provided, a separate member is required, but substantially the same effect can be obtained.

Embodiment 3
Hereinafter, Embodiment 4 of the present invention will be described with reference to FIG. FIG. 13 is a detailed view of a main part of the fourth embodiment. In the fourth embodiment, the connection portion cover 26A and the first case 70A are integrally formed, and the boundary line can be bent and stretched a predetermined number of times. A thin portion 45 is formed, and the thin portion 45 is bent and extended so that the connection portion cover 26A can be opened and closed a predetermined number of times.
Accordingly, the connection portion cover 26A can be provided in the first case 70A with a simpler structure so that the posture can be switched. The connection cover is designed to open and close only a limited number of times (usually up to 4), and is not planned to open and close dozens or hundreds of times. However, it is possible to fix the connection portion cover in the closed position in the sealed state.
In the drawing, the reference member numbers indicate the same members as in the above embodiment, although the description is omitted.
Here, instead of the sealing member 88, a breaking screw (not shown) is used as the sealing member.

  Since the present invention can more reliably prevent unauthorized attack from the connection window portion of the board box connector in a gaming machine, it can be implemented in any kind of gaming machine, and its application range is wide. Is. Further, since the disconnection of the harness can be avoided in advance when opening and closing the connection portion cover that covers the connection window portion, it is useful for various models.
