The present invention relates to gaming machines represented by pachinko machines and slot machines.
In gaming machines such as pachinko machines that use pachinko balls, for example, a main control board for overall control of games and a sub control board such as an audio lamp board, a display control board, and a payout control board are accommodated in a board box. Are arranged on the back side of the gaming machine in a state where the main control board and the sub control board are electrically connected via predetermined electrical components such as a harness and a relay board. .
In gaming machines, for the purpose of gaining unauthorized profits, the control board is illegally removed and the ROM in the board is replaced (if the CPU or ROM is a single chip, the chip is changed) to change the game contents. Many illegal actions against the control board have been reported, such as inputting illegal electric signals from the outside to the control board using lead wires, etc. In general, an improper measure such as providing a sealing mechanism is provided to prevent the substrate box from being opened without leaving it.
Examples of the gaming machine as described above include those disclosed in Patent Document 1 below. JP, 2004-033603, A As a sealing mechanism of the above-mentioned board box, a seal for sticking is stuck on an edge part of a board box, and when the board box is opened, this seal is broken, or a board The side of the box is called a breaking screw. Once the head is fastened, the head is broken. After that, the board box is not partially cut by tightening and fixing with a screw that cannot be turned. There are things that can not be opened as much as possible.
However, the sealing mechanism using the seal for sealing and the breaking screw is provided on the side portion of the substrate box, and the end edge portion of the substrate box cannot be brought into full contact. For this reason, in a portion where the sealing mechanism is not provided, there is a case where a fraud is made by inserting a fraudulent instrument into this portion. At this time, if it is the above seal for sealing, it is considered possible to affix the edge of the substrate box so as to completely cover the edge, but according to this, the visibility inside the substrate box is reduced by the seal Resulting in.
The present invention has been devised in view of such problems, and an object of the present invention is to provide a gaming machine that can effectively deter illegal acts on a board box with a simple configuration.
The gaming machine according to the present invention has as means 1,

The external force is concentrated when an external force is applied to the end edge portion of at least a part of the edge portion of the first case and the second case, or the plate portion having the end edge portion. This is characterized by providing a weakened portion that can be preferentially broken.

According to the configuration of the above means 1, when an attempt is made to pry open the board box by inserting a tool such as a screwdriver into the edge of the board box where the first case and the second case are brought together. The external force applied by is concentrated and applied to the fragile portion, and the fragile portion is preferentially broken, thereby leaving an opening trace. Therefore, illegal opening of the substrate box can be effectively prevented.
Further, at this time, the fragile portion can be provided with a simple configuration such as forming the portion fragile by forming the portion relatively thin.

Further, the gaming machine according to the present invention is a gaming machine of means 1 as means 2,
The substrate box includes sealing means for fixing and sealing the first case and the second case in a closed state.

In the present invention, “the first case and the second case are fixed and sealed in a closed state” means that the first case and the second case are fixed in a closed state without leaving any traces once they are fixed in a closed state. To prevent the first case and the second case from being moved from the closed state, that is, to make the state in which at least a part must be destroyed or cut to open the substrate box. Means.

According to the configuration of the above means 2, since the first case and the second case are sealed by the sealing means, the substrate box cannot be opened unless it is broken or cut. Not only is it difficult to do this, but even if you intend to cheat in this state, you have no choice but to give up opening the board box without leaving a trace, and therefore tend to try to force the board box open. Will become stronger, and the vulnerable part will function more effectively.

And a gaming machine that combines slot machines.

Hereinafter, embodiments of a gaming machine according to the present invention will be described with reference to the drawings. In the following embodiments, a pachinko machine will be described for the sake of convenience. However, the present invention uses a ball ball game machine other than the pachinko machine (for example, an arrange ball machine, a sparrow ball game machine, etc.), and other game balls. The present invention can be applied to various types of gaming machines.

(Front configuration of pachinko machine)
FIG. 1 is a front view of a pachinko machine 10 according to the present embodiment, FIG. 2 is a left side view of the pachinko machine 10, and FIG. 3 is a plan view thereof. FIG. 4 is a perspective view showing a state in which the inner frame 12, the front frame (set) 14, and the set plate 400 are opened with respect to the outer frame 11. (However, in FIG. 4, for the sake of convenience, the configuration in the game castle on the surface of the game board 30 (nail, center accessory, etc.) is shown blank, but the out port 36 is drawn).

As shown in FIGS. 1 to 4, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be openable and closable. I have. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of light metal such as resin or aluminum in order to reduce the weight.
The opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side of the game ball launching handle 18 (left side of the pachinko machine 10 in FIG. 1) as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the axis as the center. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. On the front side of the lower plate unit 13, there are provided a lower plate 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 (positions on the left and right upper ends of the inner frame 12). The lower tray 15 serving as a ball receiving tray is provided at a substantially central portion of the lower tray unit 13 and serves to stop a game ball discharged from the outlet 16 when the upper tray 19 described later becomes full. There is. The ball removal lever 17 is for removing a game ball in the lower plate 15. By moving the ball removal lever 17 to the left in FIG. 1, a predetermined position on the bottom surface of the lower plate 15 is opened, The game ball stopped in the tray 15 can be discharged through the opening on the bottom surface of the lower tray 15 to the player's ball storage box (dollar box).

The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launch handle 18 by the player, the game ball is driven toward the game board 30 by the game ball launch device 38 (see FIG. 4). The game ball launcher 38 includes a game ball launch handle 18, a set handle, a launch motor, and the like, which will be described later. The sound output port 24 is an output port for outputting sound from a speaker provided at the position of the upper left and right ends of the inner frame 12. Moreover, the ashtray 22 is provided on the left side of the lower tray 15 as shown in FIG. The ashtray 22 is supported so as to rotate (for example, forwardly toward the front side) about an axis line in the left-right direction (horizontal direction).

Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are molded from flame-retardant ABS resin. For this reason, this part is hard to burn.

As shown in FIG. 4, the front frame 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame 14 has an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened forward with the heart. Moreover, the front frame 14 is attached so as to fit into the outer wall (rib) 12B of the inner frame 12.
That is, since at least a part of the side surface of the front frame 14 is attached so as to fit into the outer wall (rib) 12B of the inner frame 12, foreign matter (needle-like shape) is formed from the gap between the inner frame 12 and the front frame 14. Or, it is a thin plate or the like, and specifically, it is possible to prevent illegal acts such as inserting a wire, a piano wire, a celluloid plate, etc.). Further, since the front frame 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, the front frame 14 is highly viscous and resistant to impact, and can be manufactured at low cost.

On the other hand, an upper plate 19 (see FIG. 1) as a receiving tray for game balls is provided integrally with the front frame 14 at a lower portion of the front frame 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

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

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

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 5 is a front view showing the configuration of the game board 30. Two pairs of general winning ports 31, 31 are arranged in a stepped manner at a slightly lower position on the left and right of the game board 30, and a starting port 33 is arranged at the lower center. The general winning ports 31, 31 and the starting port 33 are openings that penetrate from the game area toward the back surface, and a winning device is attached to correspond to these openings. That is, a ball detection sensor corresponding to these is provided on the back surface of the game board 30, and these sensors are connected to a main control board (main control device) to be described later through an electric wiring (not shown). .
When a game ball enters the general winning openings 31, 31 and the start opening 33, it is detected by the detection sensors, and based on the output of the detection sensors, the upper plate 19 (or the lower plate 15). When a predetermined number of prize balls are paid out and a game ball enters the start port 33, a lottery to be described later is started.

The detection results detected by the winning sensor are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is paid out from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board.
In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

In addition, a decorative symbol display device 42 using a liquid crystal panel is disposed at the center of the game board 30, and through gates 34, 34 are disposed on the left and right side portions thereof. These through gates open and close the wings of the starting port 33 described later by passing the game ball. In addition, a decorative member 35 having the above-described general winning ports 31 and 31 is provided at the lower left and right positions of the game board 30, and an out port 36 is provided at the lower part of the game board 30. A game ball that has not entered the apparatus or the like is guided through the out port 36 toward a ball discharge path (not shown) on the back of the game board 30. Further, the game board 30 is provided with a large number of guide nails for appropriately dispersing and adjusting the falling direction of the game balls, and a windmill having the same function.

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

In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of a game ball. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51.
In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 5). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 5: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner 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. 7) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said. Therefore, when it is referred to as a game area, the guide rail portion is not included, and the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail 52.

In the resin base, below the window hole 21 (game board 30), a launch rail for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. The launch rail is fixedly attached to the resin base via a metal plate behind the launch rail, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail, and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It has come to be.

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

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

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

A reference numeral 67 in FIG. 4 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / closable shutter that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction, and has a state in which the front frame 14 is opened from the inner frame 12. In the state of FIG. 4, the shutter is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like, and the discharge port 67 is closed so that the game ball does not spill from the discharge port 67.

Further, when the front frame 14 is closed, the shutter is pushed open by a ball passage rod 69 (see FIG. 4) provided on the back surface of the front frame 14 to be in a substantially horizontal state and discharged toward the discharge port 67. The played game balls are discharged to the upper plate 19 through the ball passageway 69 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game ball in the payout passage or the like spills out of the pachinko machine 10 when the front frame 14 is opened.

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

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

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.

One breaking screw 522 is set for each one. As a result, each time the cover member 501 is unsealed and released, the breaking screw is taken out one by one and inserted and screwed into the three breaking screw insertion portions 515 and 516 of the second sealing portion 520B. The unused breaking screw 522 can be securely held inside the cover member 501 in a sealed state. For example, the breaking screw accommodating portion 521 may be configured to accommodate only one breaking screw, and in this case, the breaking screw can be held inside the cover member when not in use.

Further, in the pachinko machine 10, sealing means constituted by the first and second sealing portions 520A and 520B is provided at one end portion of the cover member 501 and the position of the ball assembly plate 460 corresponding thereto. Although the structure is the same, the same or different sealing means may be provided at the other end portion, thereby fixing both ends of the cover member 501 in a sealed state. In this case, sealing means may be further provided at an end portion of the cover member 501 provided with an opening / closing structure (a structure that is pivotally supported), but both end portions are fixed by the sealing means. The open / close structure can be omitted.

In the pachinko machine 10, the cover member 501 is provided so as to cover the back surface of the ball assembly plate 460 on the back surface of the game board 30, so that the relay board, wiring, etc. disposed on the back surface of the ball assembly plate 460 are provided. The electric parts can be protected, and the electric parts can be prevented from being broken or disconnected due to the assembly of other electric parts or the contact of other parts from the outside. That is, in assembling the pachinko machine 10, for example, electrical components such as a relay board, LED board, switch, and wiring are attached to the ball assembly plate 460, and a cover member 501 is attached to the ball assembly plate 460 to form a unit. Then, if this unit is attached to the game board 30 and then the first control board unit 201 is attached, the workability is improved. In such a case, at least a part of the electrical components is also covered by the cover member 501. By being covered with the cover, the electrical component is protected by the cover member 501, and the electrical component is prevented from being damaged during the mounting operation.

In addition, a gap between the back surface of the game board 30 and the first control board unit 201 is compensated, so that a space for performing an illegal act is not formed.
Furthermore, since this cover member 501 is fixed in a state of being sealed by the sealing means 520, it is difficult to remove it illegally, and even if this seal is illegally broken, there is no trace. Since it remains, it is obvious at a glance that the seal has been broken, which makes it easy to detect fraud.

Further, the sealing means includes a first sealing portion 520A and a second sealing portion 520B, and the first sealing portion 520A is inserted into the ball assembly plate 460 from the game board 30 side so that the cover member 501 is sphered. Screws 519 which are fixing means for fixing to the collective plate 460, a recess 465 provided on the bottom plate with a hole provided on the game board 30 side of the ball collective plate 460, and a screw 519 provided on the cover member 501. The ball assembly plate 460 is attached to the game board 30 because the insertion portion 514 is inserted and fixed, and the cutting portion 514A is provided in the insertion portion 514 to release the fixed state by the screw 519. In this state, it is impossible to remove the screw 519 from the outside. As a result, the cover member 501 is fixed in a sealed state, and if it is illegally removed without leaving any trace, It becomes necessary to remove the set plate 460 from the game board 30, thus making it difficult to carry out the fraud. On the other hand, for example, when the cover member 501 is opened for the purpose of inspecting the back side of the ball assembly plate 460, the sealing state of the cover member 501 can be released while leaving a trace by cutting the cutting portion 514A. Further, when the ball assembly plate 460 is not attached to the game board 30, the cover member 501 can be freely opened, so that workability is good.

Furthermore, the second sealing portion 520B is inserted into the cover member 501 from the back side, and a break screw 522 that fixes the cover member 501 to the ball assembly plate 460, and a hole provided in the cover member 501 through which the break screw 522 is inserted. Breaking screw insertion portions 515 and 516 having a bottom plate, screw insertion portions 463 and 464 provided on the ball assembly plate 460 into which the breaking screws 522 are screwed, and a breaking screw insertion portion for releasing the fixed state by the breaking screws 522 The cover member 501 can be fixed to the spherical assembly plate 460 from the outside by the breaking screw 522, and thus the cover member 501 can be easily fixed. It can be fixed in a sealed state. At this time, even when the ball assembly plate 460 is attached to the game board 30, the cover member 501 can be sealed and fixed to the ball assembly plate 460 from the outside by the breaking screw 522. After releasing the sealing state by the first sealing portion 520A, the cover member 501 and the ball assembly plate 460 can be sealed again by the second sealing portion 520B. On the other hand, when the cover member 501 is opened for the purpose of, for example, inspecting the back side of the ball assembly plate 460, the sealing state of the cover member 501 is released while leaving traces by cutting the cutting portions 515A and 516A. Can do.

Furthermore, one end portion of the first control board unit 201 is pivotally attached by the shaft 411, and the breaking screw insertion portion 515 is close to the shaft 411 that pivotally attaches the first control board unit 201. Even if the first control board unit 201 is illegally removed from the pivoting portion, it is difficult to remove the pivoting portion due to the broken screw insertion portion 515 and the cover member 501 is sealed. Therefore, it is difficult to remove the breaking screw insertion portion 515 without leaving a trace even if it is attempted to remove the breaking screw insertion portion 515. Therefore, fraud is more effectively prevented.

Furthermore, a break screw accommodating portion 521 that accommodates one or more break screws 522 for the second sealing portion 520B is disposed inside the cover member 501, so that the break screw accommodating portion 521 has a break screw. If 522 is accommodated, every time the sealing of the cover member 501 is released and opened, the breaking screw 522 is taken out one by one and the next sealing is performed by the second sealing portion 520B. In the stage where there is an unused breaking screw 522, it can be securely held inside the cover member 501 in a sealed state.

Furthermore, the first sealing portion 520A is provided in the corner portion of the cover member 501, and the second sealing portion 520B is provided in addition to the corner portion, so that the cover member 501 is cornered by the first sealing portion 520A. Thus, the cover member 501 can be sealed more easily and reliably by the second sealing portion 520B. In addition, since the first and second sealing portions are provided at a plurality of places, if sealing and releasing are performed at one place for each time of performing sealing and releasing, sealing and releasing are performed. This process can be performed a plurality of times, and an opening history can be left for each process.

Further, since the cover member 501 is formed into a hollow body and the inside is partitioned into a number of chambers by the ribs 512, a sufficient space is provided in the cover member 501 to install an unauthorized substrate. Therefore, cheating can be effectively prevented.

Furthermore, since the cover member 501 has a configuration in which the surface facing the ball assembly plate 460 is opened, the opened surface is also in contact with the ball assembly plate 460 when the cover member 501 is closed. For this reason, fraudulent acts such as installing an unauthorized substrate inside the cover member 501 are difficult. At this time, as described above, even if the inside of the cover member 501 is partitioned into a number of chambers by the ribs 512, if the open part of the cover member 501 is exposed to the outside, the ribs 512 are cut from the outside and the illegal action However, it is also difficult to cut the rib 512 by making the open surface of the cover member 501 face the spherical assembly plate 460 as described above.

Furthermore, since the cover member 501 and the first control board unit 201 have an open / close structure that opens and closes in the opposite direction, the cover member 501 and the first control board unit 201 are opened. Is not concentrated on either one of the left and right ends, but is distributed on both the left and right ends. Therefore, for example, when the cover member 501 and the first control board unit 201 are opened for inspection or the like, a problem such as deformation of the spherical assembly plate 460 due to the load of the cover member 501 and the first control board unit 201 is prevented. The If the ball assembly plate 460 is deformed, there is a risk that the game balls may be discharged.

Further, one end of the first control board unit 201 is pivotally attached to the shaft 411 and is locked to the cover member 501 to the other end (free end) of the first control board unit 201. By adopting a configuration in which the pieces are integrally molded, it is not necessary to separately prepare a member (for example, a ny latch) for holding the free end portion of the first control board unit 201, and the number of parts can be reduced. Further, if the cover member 501 is illegally removed, the free end portion of the first control board unit 201 is released without being held, so that an illegal act can be easily detected, and therefore illegal acts are performed. It becomes more difficult.

In the assembly of the pachinko machine 10, for example, electrical components such as a relay board, an LED board, a switch, and a wiring are attached to the ball assembly plate 460, and a cover member 501 is attached to the ball assembly plate 460 to configure them as a unit. If the unit is attached to the game board 30 and then the first control board unit 201 is attached, the workability is improved. In such a case, at least a part of the electrical components is covered by the cover member 501. By making it cover, an electrical component is protected by the cover member 501, and it is prevented that an electrical component is damaged at the time of an installation operation | work.
FIG. 23 shows a state in which the cover member 501 and the first control board unit 201 are attached to the ball assembly plate 460. In this manner, the ball assembly plate 460, the cover member 501, and the first control board unit are shown. A process of attaching 201 to the game board 30 in an integrated state is also possible, and the assembly method of the pachinko machine 10 is not limited to a specific one, but as described above, the game is performed with the ball assembly plate 460 and the cover member 501 as a unit. The workability of the process of attaching the first control board unit 201 after being attached to the panel 30 is particularly good.

(Feature configuration)
FIGS. 25 to 44 are diagrams showing the configuration of the second control board box 202A for accommodating the sound lamp control board which is one of the sub control boards. Hereinafter, the configuration of the second control board box 202A will be described with reference to FIG.

The second control board box 202A is mounted on the mount and unitized as the second control board unit 202 described above, and is arranged on the back side of the pachinko machine 10 as described above.

The second control board box 202A includes a box cover 601 that covers the front side of the sound lamp control board and a box base 602 that covers the back side of the sound lamp control board. The box cover 601 and the box base 602 correspond to the first case and the second case, but it is arbitrary which of the box cover 601 and the box base 602 is the first case and which is the second case. is there. The second control board box 202A accommodates the sound lamp control board in the state where the first case, ie, the box cover 601 and the second case, ie, the box base 602, each having a plurality of plate portions forming the outer surface are brought together. It becomes the composition which is done.

The box cover 601 and the box base 602 are each formed by forming a transparent resin into a substantially horizontally long rectangular shape, and the box cover 601 is a cover having a slight thickness, an accommodation space formed inside, and one side opened. The box base 602 is a flat member that covers the open side of the box cover 601. As shown in FIGS. 27 and 28, the box cover 601 is provided at six locations at equal intervals from one end to the other end along one short edge (left edge in FIG. 27, right edge in FIG. 28). The stays 603 are respectively arranged and supported by the tip of the stay 603, and the pivot shaft 604 is formed to extend in parallel with one short edge of the box cover 601. The stay 603 and the pivot shaft 604 are formed integrally with the box cover 601, and a slit 605 surrounded by the stay 603 and the pivot shaft 604 and one short edge of the box cover 601 is provided. The box cover 601 is formed at five locations at equal intervals along one short edge. As shown in FIGS. 29 and 30, the box base 602 has pivoting pieces 606 at five locations at equal intervals along one short edge (the right edge in FIG. 29 and the left edge in FIG. 30). Are formed respectively. Each pivot piece 606 has a curved shape corresponding to the peripheral surface of the pivot shaft 604 of the box cover 601 and is an extended piece having a width smaller than the length of the slit 605 of the box cover 601. . The pivot piece 606 is inserted into the slit 605 and supported by the pivot shaft 604 so as to be rotatable within a certain angle range, and slide within the slit 605 in the length direction of the slit 605. Thus, the box cover 601 and the box base 602 are connected to each other so as to be rotatable and slidable between the short sides, and can be opened and closed.

As shown in FIG. 26, the short edge (the right edge in FIG. 26) opposite to the short edge of the pivot base piece 606 in the box base 602 is directed toward the side facing the box cover 601 (ie, the inside). The locking pieces 607 extending vertically and extending vertically at a right angle downward to form a hook shape as a whole are formed at four locations at equal intervals. On the other hand, an engagement groove 608 corresponding to each locking piece 607 of the box base 602 is formed on the short edge (the left end edge in FIG. 26) opposite to the short edge on the pivot shaft 604 formation side in the box cover 601. Each is formed. Each engaging groove 608 is a lumen (not shown) that can be engaged with the tip of the locking piece 607 and hold the locking piece 607 when the locking piece 607 is inserted and slid downward. It is formed in the shape which has. In addition, a large number (eight places) of extended pieces 609 are formed at the lower end edge of the box base 602, and a large number (eight places) of fitting portions 610 into which the extended pieces are inserted and fitted are formed at the upper end edge. In addition, a large number (eight places) of fitting portions 611 corresponding to the extending pieces 609 of the box base 602 are provided at the lower end edge of the box cover 601, and the fitting portions 610 of the box base 602 are provided at the upper end edge. A large number (eight points) of extended pieces 612 are formed, and the extended pieces 609 and 612 are fitted into the corresponding fitting portions 611 and 610, respectively, so that the box cover 601 and the box base 602 are peripheral. The parts are fitted and held in a closed state, and the structure needs to be released from the fitted state when opening from the closed state.

A break screw insertion portion 613 is formed at the center of the lower end edge of the box cover 601, and a screw insertion portion 614 is formed at the center of the lower end edge of the box base 602 corresponding to the break screw insertion portion 613. The breaking screw insertion portion 613 and the screwing portion 614 have the same configuration as the breaking screw insertion portion 515 and the screwing portion 463 formed on the cover member 501 and the ball assembly plate 460, respectively, and the breaking screw insertion portion. A breaking screw is inserted from the outside of 613 and screwed into the screwing portion 614 to be fastened and fixed.

Hereinafter, the closing operation of the box cover 601 and the box base 602 will be sequentially described. First, as shown in FIGS. 25 and 26, the pivot piece 606 of the box base 602 is inserted into the slit 605 of the box cover 601 and positioned on the upper end side in the slit 605. In this state, the box cover 601 is displaced downward with respect to the box base 602 by a predetermined difference (that is, a distance corresponding to the slidable range of the pivot piece 606 in the slit 605). As described above, the relative positions of the box cover 601 and the box base 602 are moved from the closed position to the direction of opening the second control board box 202A, which will be described later. In this case, the engagement state between the box cover 601 and the box base 602 is released, that is, this is the “open position”.
Next, the box cover 601 and the box base 602 are overlapped by rotating around the pivot shaft 604 in the open position, and the locking piece 607 of the box base 602 is inserted into the engaging groove 608 of the box cover 601. The state at this time is shown in FIG. 31 and FIG. As shown in the figure, in this state, the box cover 601 and the box base 602 are superposed at the open position.
Next, the box cover 601 and the box base 602 are slid to a position where the upper and lower ends are aligned with each other, and the extended piece 609 of the box base 602 is moved to the fitting portion 611 of the box cover 601 and the extended piece 612 of the box cover 601 is moved. Are fitted into the fitting portions 610 of the box base 602, respectively. The state at this time is shown in FIG. 33 and FIG. In this state, in the box cover 601 and the box base 602, the extending pieces 609 and 612 are fitted into the fitting portions 611 and 610 as described above, and the locking pieces 607 of the box base 602 are engaged with the box cover 601. The box cover 601 and the box base 602 are held in a closed state by engaging with the mating groove 608. The relative position when the box cover 601 and the box base 602 are aligned without being displaced in the vertical direction, that is, in the sliding direction, is a position where the second control board box 202A is in a state where the sound lamp control board is accommodated. In this case, when the box cover 601 and the box base 602 are moved from the open position in the closing direction of the second control board box 202A, the slide cover cannot move any more. "Position".
Next, a rupture screw is inserted from the outside of the rupture screw insertion portion 613 and screwed into the screw insertion portion 614 and finally tightened to break the head. As a result, the box cover 601 and the box base 602, that is, the second control board box 202A are sealed, and in order to open the second control board box 202A, it is necessary to destroy or cut at least a part thereof.

When opening the second control board box 202A in the closed state, for example, the broken screw insertion portion 613 is cut with a nipper or the like to release the sealed state, and the box cover 601 and the box are reversely connected to the above procedure. The base 602 is slid from the closed position to the open position, and is rotated to open.

As described above, since the box cover 601 and the box base 602 are configured to open and close through the two operations of the slide operation and the rotation operation, the second control board box 202A is more difficult to open, and unauthorized opening is more reliably performed. It is to be prevented. In particular, the pivoting operation requires a space in the front-rear direction, but since the cover 300 is disposed on the back side of the second control board box 202A as shown in FIGS. 6 and 7, the second control board box 202A has a structure that is difficult to open depending on the turning operation. Further, by adopting a structure in which the box cover 601 and the box base 602 are slid in a direction parallel to the substrate surface, the entire periphery can be reliably fitted with a simpler structure, and the second control board can be fitted. The box 202A can be more easily and reliably closed.

As shown in FIGS. 26, 29, and 30, a fragile portion 631 is provided at the lower end edge of the box base 602. The fragile portion 631 is configured by forming the lower end edge of the box base 602 in a comb shape in which a large number of convex portions 632 are continuous. Each of the convex portions 632 has a substantially rectangular shape, and is formed on the lower end edge of the box base 602 almost entirely except for the positions where the extension pieces 609 and the screwing portions 614 are formed.

The convex portion 632 includes three types, a width w1 having a slightly large width, a medium width, and a slightly small width w1. The width w1 is a large width of about 5 mm, a medium width of about 4.5 mm, A small one is about 4 mm. Further, the interval d1 between the convex portions 632 is about 3 mm, and the protruding length h1 is about 4 to 4.5 mm.

As shown in FIGS. 26 and 28, a large number of convex portions 633 are formed on the lower end edge of the box cover 601 so as to mesh with the large number of convex portions 632 of the box base 602. A flange 635 extending downward from the inner edge of the bottom surface portion 634 is formed at the lower end portion of the box cover 601, and the lower end edge of the flange 635 extends so as to be bent at right angles to the lower edge. A wall 636 is formed. The convex portion 633 is formed in a rectangular wall shape extending perpendicularly from the inner surface of the flange 635 and the upper surface of the lower edge wall 636. The width, interval, and protruding height of the convex portions 633 are set so as to correspond to the multiple convex portions 632 of the box base 602, respectively, and the box base 602 is interposed between the convex portions 633 of the box cover 601. The projections 632 and 633 are arranged and configured so that the projections 632 and 633 engage with each other.

In the present embodiment, the position where the lower end edges of the box cover 601 and the box base 602 are brought together to close the second control board box 202A is the inner edge of the bottom surface portion 634 of the box cover 601. The fragile portion 631 is provided so as to extend outward from the closed position of the second control board box 202A. That is, in a state where the box cover 601 and the box base 602 are in the closed position, the convex portion 632 of the box base 602 is positioned below the bottom surface portion 634 of the box cover 601. Further, a ridge 637 extending inward and extending in the horizontal direction is formed above the fragile portion 631 of the box base 602, and this ridge is in a state where the box cover 601 and the box base 602 are in the closed position. 637 is positioned close to the bottom surface portion 634 of the box cover 601.

(Function)
As described above, in the pachinko machine 10, an audio lamp is provided inside the box cover 601 as the first case and the box base 602 as the second case, each having a plurality of plate portions forming the outer surface. In the configuration in which the second control board box 202A having a configuration in which the control board is accommodated is provided, the lower end edge of the box cover 601 and the box base 602 that are brought into contact with each other is arranged with respect to the lower end edge. Since the weakened portion 631 that can be preferentially broken when the external force is concentrated when the external force is applied is provided, the lower end edge of the box cover 601 and the box base 602 of the second control board box 202A that are brought together. For example, an instrument such as a driver is squeezed into the part to squeeze open the second control board box 202A. If, external force applied by the operation fragile portion 631 is applied to concentrate it is broken preferentially to fragile portion 631, so that the thereby leaving a tamper. Therefore, unauthorized opening of the second control board box 202A can be effectively prevented.
At this time, the fragile portion 631 is provided with a simple configuration in which the lower end edge of the box base 602 is formed in a comb shape in which a large number of convex portions 632 are continuous.

Further, since the second control board box 202A includes the breaking screw insertion portion 613 and the screwing portion 614 as sealing means for fixing and sealing the box cover 601 and the box base 602 in the closed state, the box cover 601 and the box Since the base 602 is sealed by the sealing means, the second control board box 202A cannot be opened unless the second control board box 202A is broken or cut. Therefore, it is difficult to open the second control board box 202A illegally. In addition, even if the user intentionally cheats in this state, opening the second control board box 202A without leaving a trace has to be abandoned, and therefore, the second control board box 202A is forced to be opened. The weakness part 631 comes to function more effectively.

43 is an enlarged view showing the state of the lower edge portion of the second control board box 202A in the closed state, and FIG. 44 is a cross-sectional view taken along the line AA of FIG. When the second control board box 202A is closed, that is, when the box cover 601 and the box base 602 are in the closed position, as shown in FIG. 43, the lower edges of the box cover 601 and the box base 602 are attached to each other. It is matched. At this time,
Since the box cover 601 and the box base 602 are sealed by the breaking screw insertion portion 613 and the screwing portion 614, even if an intentional misconduct is intended in this state as described above, the second control board box 202A is traced. It is impossible to open the package without leaving it. For this reason, there is a possibility that the second control board box 202A may be opened by breaking the sealing state at the breaking screw insertion portion 613 and the screwing portion 614 even if a trace is left, but the breaking screw insertion portion 613 and the screwing portion 614 may be opened. 44, as shown in FIG. 44, an instrument R such as a flat-blade screwdriver is inserted into the gap between the box cover 601 and the box base 602 to widen the gap between these parts, and then an illegal instrument is used from there. There is also a possibility that fraud is made inside the second control board box 202A. In the latter method, if it works well, it seems that it is possible at first glance to return the expanded gap to its original shape so that no trace is left, so the latter method can be implemented rather than the former method. It is thought that the nature is high. In the case of the latter method, the instrument R that has been put into the gap between the box cover 601 and the box base 602 is twisted as indicated by an arrow A1 in the drawing, or as indicated by an arrow A2 in the drawing. The handle side is pushed down to act as a “lever” and the gap in this part is pushed and widened. Here, since the fragile portion 631 is formed at the lower end edge of the box base 602, the external force applied using the instrument R as described above is concentratedly applied to the fragile portion 631, and the arrow B1 in the figure is applied. As shown in FIG. 5, the fragile portion 631 is preferentially broken so as to be bent, thereby reliably leaving an opening trace.

Further, the box cover 601 and the box base 602 are configured to be able to be opened and closed by sliding each other, and provided with a fitting mechanism for fitting the box cover 601 and the box base 602 to each other in a closed state. The box cover 601 and the box base 602 are held in a closed state so as to be fitted by a fitting mechanism, and the box cover 601 and the box base 602 are not sealed by the sealing means, or the box cover Even when the seal between the box base 602 and the box base 602 is broken, the box cover 601 and the box base 602 cannot be opened simply by sliding, and the fitting by the fitting mechanism can be released. For this reason, the box cover 601 and the box base 602 are omitted. It made a strong tendency to pry into. Therefore, the fragile part functions more effectively.

Further, since the weak part 631 is formed by forming the edge of the box base 602 in a comb shape in which a large number of convex parts 632 are continuous, the weak part easily breaks when trying to pry it open with an instrument such as a driver. Part 631.

In addition, since a large number of convex portions 632 are formed to have a width of about 4 to 5 mm and a distance of about 3 mm, it is difficult to insert a screwdriver or the like, and it is difficult to pry open, and has sufficient vulnerability. In addition, the protrusion 632 has a necessary strength and has a width and an interval that are not difficult to form.

In addition, since a large number of convex portions 633 are formed at the edge of the box cover 601 so as to mesh with the large number of convex portions 632 of the box base 602, both the box base 602 and the box cover 601 are convex. By forming the parts 632 and 633, a function as a fragile part is given, and the function can be achieved more reliably. In addition, since the convex portions 632 and 633 formed on the box base 602 and the box cover 601 are engaged with each other, the second control board box 202A is more reliably formed at the convex portions 632 and 633 forming portions. The structure is closed.

Further, the box cover 601 and the box base 602 are configured to be opened and closed by sliding each other, and an extending piece 609 extending along the sliding direction is formed at the lower end edge of the box base 602. A fitting portion 611 into which the extending piece 609 is inserted and fitted is formed at the lower edge of the box cover 601, and extends along the sliding direction at the upper edge of the box cover 601. Since the extended piece 612 is formed and the fitting portion 610 into which the extended piece 612 is inserted and fitted is formed at the upper end edge of the box base 602, the edge portions of the box cover 601 and the box base 602 are formed. When the extended pieces 609 and 612 are inserted and fitted into the fitting portions 611 and 610, they are regulated so that they can move only in the sliding direction. . Therefore, when trying to open the box cover 601 and the box base 602 illegally, the tendency to forcibly open the box cover 601 and the box base 602 in the sliding direction from the end edge portion becomes strong, and the weakened portion 631. Is configured to function more effectively.

In addition, the weakened portion 631 is located outside the position where the end edges of the box cover 601 and the box base 602 are brought into contact with each other to close the second control board box 202A, that is, the inner edge of the bottom surface portion 634 of the box cover 601. Therefore, even when the fragile portion 631 is broken, the second control board box 202A is closed on the inner side of the fragile portion 631. Therefore, the second control board box 202A accommodates the sound lamp control board. 2 The basic function as the control board box 202A is not impaired, and an opening is not formed by the breakage of the fragile portion 631, and an unauthorized entry is not made from the opening.

Further, since the box cover 601 and the box base 602 are configured to be opened and closed through two operations of a sliding operation and a rotating operation, the second control board box 202A is more difficult to open, and an illegal Opening is more reliably prevented. In particular, since the rotation operation requires a space in the front-rear direction, the cover 300 is disposed on the back side of the second control board box 202A, so that the second control board box 202A is opened by the rotation operation. It has a difficult structure.

(Modification)
In the embodiment, the fragile portion 631 is configured by forming the edge of the box base 602 in a comb shape in which a large number of convex portions 632 are continuous. However, as the fragile portion, the board box is illegally formed. If the external force applied when trying to pry open intended to be opened has a vulnerability that can be preferentially broken to leave an opening trace, the vulnerability of the above embodiment Arbitrary structures other than the part 631 can be adopted. FIG. 45 is a schematic cross-sectional perspective view showing another example of the fragile portion. The weakened portion 638 shown in the figure is configured by forming the edge portion of the box base 639 to be relatively thin. The main body 639B of the box base 639 is shaped so that the wall thickness t1 is about 2 mm on average, although there are some differences depending on the part, but the band about several millimeters wide from the lower edge of the box base 639 is The wall thickness t2 is smaller than the wall thickness t1 of the main body 639B, that is, less than 2 mm, thereby forming the fragile portion 638 having the above-described fragility. The outer surface of the fragile portion 638 is flush with the outer surface of the main body 639B, and the fragile portion 638 is formed so that the thickness of the fragile portion 638 approaches the outer side of the box base 639. Further, a ridge 640 extending inward and extending in the horizontal direction is formed above the fragile portion 638, and the ridge 640 is the same as the ridge 637 in the above embodiment. According to the said structure, the structure of the weak part 638 is simpler and the shaping | molding is comparatively easy.

FIG. 46 is a schematic sectional perspective view showing still another example of the fragile portion. The weakened portion 641 shown in the figure is configured by forming a groove 643 in the vicinity of the edge of the box base 642. The groove 643 is formed on the inner surface of the box base 642 slightly above the lower end edge (that is, the plate portion having the lower end edge) so as to extend in the horizontal direction along the lower end edge. According to the above configuration, the box base 642 is locally thin at the position of the groove 643, and therefore, an external force applied to the lower edge when the substrate box is to be pry open is provided in the groove 643. The application is concentrated at the position, so that the external force is concentrated more locally, and the structure can be more effectively broken at the position.

Moreover, in the said embodiment, although the width | variety w1 of the convex part 632 was about 4-5 mm and the space | interval d1 was about 3 mm, of course, the width | variety and space | interval of a convex part are not limited to this, For example, The thickness may be equal to or less than the thickness of the substrate box (for example, approximately 2 mm or less in the case of the second control substrate box 202A of the above embodiment). If the width and interval of the protrusions are equal to or less than the thickness of the substrate box, the driver or the like is further difficult to insert and difficult to pry, and is more fragile and more likely to break.

In the above embodiment, the box cover 601 and the box base 602 are configured to be opened and closed through a sliding operation and a rotating operation. However, the box cover 601 and the box base 602 can be opened and closed by only one of the sliding operation and the rotating operation. It is good also as a structure which can do. FIG. 47 is a diagram schematically illustrating an example of a configuration of a substrate box that can be opened and closed only by a pivoting operation. In the example shown in the figure, the box cover 644 and the box base 645 of the board box are formed in a substantially horizontally long rectangular shape, and are pivotally attached to one short edge so as to be indicated by an arrow A3 in the figure. The fragile portion 646 is formed on the short edge (free edge) opposite to the pivoted short edge (fixed edge) of the box base 645. Yes. The configuration of the fragile portion 646 is basically the same as that of the fragile portion 631 in the embodiment. In the case of a substrate box configured to open and close only by a pivoting operation in this way, if it is attempted to pry open illegally, there is the highest possibility of prying open a tool such as a screwdriver at the free edge. Since it is high, unauthorized opening can be effectively suppressed by forming a weak part in a free edge part. In addition, if fragile portions are formed on edge portions other than the fixed edge portion and the free edge portion (that is, both the upper and lower long edges in the example shown in FIG. 47), unauthorized opening is prevented. More desirable.

In the above embodiment, the box cover 601 and the box base 602 are sealed. However, for example, the fitting structure or the engagement between the box cover and the box base is not necessary. Even if the combined structure is appropriately complicated to make it difficult to open and close the substrate box, the fragile portion can be made to function.

Moreover, in the said embodiment, the box cover 601 and the box base 602 fit the extension pieces 609 and 612 formed in each upper end edge and lower end edge, and the fitting parts 611 and 610 corresponding to this. It was configured to be fitted and closed between the peripheral portions by this, but as a fitting mechanism between the box cover and the box base, in place of the above embodiment, or In addition to the embodiment, for example, a fitting mechanism as shown in FIG. 48 may be provided. In the example shown in the figure, the peripheral edges 631P and 632P are formed by extending the edges of the box cover 631 and the box base 632 in opposite directions so as to form a cross-sectional shape, and the peripheral walls of the box base 632 are formed. A fitting rib 632R is formed in parallel with the peripheral wall 632P on the inner peripheral side slightly from 632P. According to this configuration, when the box cover 631 and the box base 632 are in the closed position, the peripheral wall portion 631P of the box cover 631 is inserted between the peripheral wall portion 632P of the box base 632 and the fitting rib 632R. The box cover 631 and the box base 632 are fitted to each other, and the sliding movement thereof is restricted, and the box cover 631 and the box base 632 are securely held closed. When opening the box cover 631 and the box base 632, it is necessary to remove the peripheral wall portion 631P of the box cover 631 from between the peripheral wall portion 632P of the box base 632 and the fitting rib 632R. Yes. The fitting rib as described above may be provided on any of the box cover and the box base, and may be provided on the entire periphery or may be selectively provided on one or a plurality of end edges. Furthermore, it may be formed so as to be long and continuous, or may be formed locally to be short, and may be provided at a plurality of positions at intervals.

Further, the configuration of the weakened portion and the like in the second control board box 202A of the above embodiment can be similarly applied to other board boxes such as the first control board unit 201A and the third control board unit 203.
