18A and 18B are views for explaining the second state of the ROM cassette, where FIG. 18A is a view of the ROM cassette from above, and FIG. 18B is a view of the ROM cassette from below.
As shown in FIG. 17, in the first state, the cassette main body 40B is in a state of being closer to the second fixed portion 44 side in the cassette case 40A.
As shown in FIG. 18, in the second state, the cassette main body 40B is in a state of being closer to the locked portion 42 and the first fixed portion 43 side in the cassette case 40A.
The cassette case 40A is provided with a notch 48 in the vicinity of the first fixed portion 43 on the side wall of the long side on the side provided with the first fixed portion 43. The action of the notch 48 will be described in detail below.

19 and 20 are diagrams illustrating a procedure for attaching the ROM cassette to the effect board case.
FIG. 19 describes a case where the ROM cassette can be correctly attached to the effect board case.
FIG. 19A shows the state of the cassette mounting portion 104 of the board cover 100A before mounting the ROM cassette 40.
In the cassette mounting portion 104, the connector 81 of the first staging board 55 included in the staging board case 100, the positioning pin 105 for positioning the cassette body 40B, the claw portion 110, and the first fixing portion 111 are exposed. It is in a state.
In this state, the ROM cassette 40 is not attached to the effect board case 100, and the removable parts (such as the button battery described above) of the effect board case 100 can be accessed and attached / detached.
As described above, the claw portion 110 projects downward with a space 110a between the claw portion 110 and the surface of the cassette mounting portion 104, and fixes the second fixed portion 44 with the surface of the cassette mounting portion 104. It is a member to be used.

From such a state, in FIG. 19B, the ROM cassette 40 in the first state (FIG. 17) is attempted to be attached to the cassette mounting portion 104.
As shown in FIG. 19B, in the ROM cassette 40 in the first state, when the positioning pin 105 of the cassette mounting portion 104 is inserted into the insertion hole 45 of the cassette main body 40B, the claw portion 110 of the board cover 100A is inserted. Is housed in the notch 48 in the cassette case 40A.
The claw portion 110 does not interfere with the cassette case 40A, and the operator pushes down the entire ROM cassette 40 toward the effect board case 100 to completely complete the connector 91 of the cassette body 40B and the connector 81 of the first effect board 55. Can be connected to. The first fixed portion 43 and the second fixed portion 44 of the cassette case 40A and the cassette main body 40B can all come into contact with each other on the surface of the cassette mounting portion 104 of the substrate cover 100A.
At this time, the first fixed portion 43 of the cassette case 40A is located on the opposite side of the notch portion 48 with the claw portion 110 interposed therebetween.

According to the present embodiment, in a state where the positioning pin 105 of the effect board case 100 (cassette mounting portion 104) is inserted into the insertion hole 45 of the cassette body 40B, the ROM cassette 40 is simply pushed down straight to form the effect board case 100. Since the connector 81 and the connector 91 of the ROM cassette 40 can be connected, there is no concern that both connectors will be damaged due to unnecessary stress.
However, at this stage when the ROM cassette 40 is still in the first state, the position of the locked portion 42 of the cassette case 40A does not match the position of the locked portion 109 of the substrate cover 100A. Therefore, the ROM cassette 40 cannot be fastened (locked) to the staging board case 100 by locking the locked portion 42 and the locked portion 109.
The cassette body 40B is positioned on the board cover 100A by the insertion hole 45 and the positioning pin 105, but as described above, the cassette case 40A can move relative to the cassette body 40B.
That is, the ROM cassette 40 can be transferred from the first state to the second state (FIG. 18) with the cassette body 40B attached to the substrate cover 100A.

As shown in FIG. 19 (c), the cassette case 40A is slid and moved in the direction of the arrow in the figure. At this time, the first fixed portion 43 moves toward the first fixed portion 111 provided on the side wall portion 104a of the cassette mounting portion 104, and the tip of the first fixed portion 43 is the claw portion 110 and the cassette mounting portion 104. It moves in the direction of entering the space 110a between the surface and the surface of the space 110a.
During this time, the claw portion 110 functions as a guide means for guiding the slide movement of the cassette case 40A.

The cassette case 40A is slid and moved, and finally, as shown in FIG. 19D, the ROM cassette 40 is completely in the second state. At this time, the first fixed portion 43 is completely inserted and fixed in the first fixed portion 111, and the tip 43a of the second fixed portion 43 completely enters the space 110a below the claw portion 110. It is fixed.
Further, since the position of the locked portion 42 coincides with the position of the locked portion 109 provided on the substrate cover 100A, the locked portion 42 and the locked portion 109 are connected by a locking pin (sealing member). By locking, the cassette case 40A can be fastened (locked) to the effect board case 100. The claw portion 110 functions as a lock (fixing) member for locking (fixing) the ROM cassette 40 to the substrate cover 100A.

The state shown in FIG. 19D is a mounting state in which the ROM cassette 40 is attached to the staging board case 100 regardless of whether or not the cassette case 40A is locked to the staging board case 100. In this state, the removable parts (button batteries, etc.) of the staging board case 100 cannot be attached or detached.
In order to remove the ROM cassette 40 from the effect board case 100, the reverse procedure described with reference to FIG. 19 may be performed. That is, after releasing the fastening between the locked portion 42 and the locked portion 109, the cassette case 40A is slid in the direction opposite to the arrow in FIG. 19 (c). As a result, when the ROM cassette 40 returns from the second state to the first state, the fixing of the first fixed portion 43 by the first fixing portion 111 and the fixing of the second fixed portion 43 by the claw portion 110 are released. The state is as shown in 19 (b).
Therefore, by pulling out the ROM cassette 40, the ROM cassette 40 can be removed from the staging board case 100.

The ROM cassette 40 can be attached to the effect board case 100 when it is in the first state (FIG. 17), and can be attached to and locked to the effect board case 100 in the first state (FIG. 18). On the other hand, the ROM cassette 40 in the second state cannot be attached to the staging board case 100.

FIG. 20 describes a case where the ROM cassette cannot be correctly attached to the effect board case.
FIG. 20 (a) shows the cassette mounting portion 104 in the same state as in FIG. 19 (a). When the ROM cassette 40 in the second state is to be attached to the cassette attachment portion 104 in this state, the state is as shown in FIG. 20 (b).
That is, as shown in FIG. 19B, in the ROM cassette 40 in the first state, when the positioning pin 105 of the cassette mounting portion 104 is inserted into the insertion hole 45 of the cassette body 40B, the board cover 100A The claw portion 110 interferes with the cassette case 40A in the form that the first fixed portion 43 of the cassette case 40A rides on the claw portion 110. The second fixed portion 44 also rides on the side wall portion 104a of the cassette mounting portion 104.

In this state, the operator cannot push down the entire ROM cassette 40 toward the effect board case 100 to connect the connector 91 of the cassette body 40B and the connector 81 of the first effect board 55. The ROM cassette 40 is in a state of floating from the surface of the cassette mounting portion 104 of the board cover 100A.
The position of the locked portion 42 of the cassette case 40A and the position of the locked portion 109 of the board cover 100A are substantially the same, but since the ROM cassette 40 is floating from the surface of the cassette mounting portion 104, it is locked. The portion 42 and the locked portion 109 cannot be locked.
If the operator forcibly pushes down the ROM cassette 40 as it is, the cassette case 40A may be destroyed. However, in the case of FIG. 20, the length of the positioning pin 105 provided in the cassette mounting portion 104 is such that the connector 81 on the effect board case 100 side and the connector 91 on the ROM cassette 40 side do not come into contact with each other. Even if the ROM cassette 40 is forcibly pushed down, there is no concern that both connectors will be stressed and damaged.
The claw portion 110 functions as a regulating member that does not restrict the attachment of the ROM cassette 40 in the first state to the effect board case 100, but restricts the attachment of the ROM cassette 40 in the second state to the effect board case 100. do.

Conventionally, complicated work has been required to rewrite and reuse the programs and data stored in the program ROM mounted on the first staging board 50 and the data ROM mounted on the second staging board 70. ..
After unsealing and opening the board case accommodating the first production board 50 and the second production board 70, the production ROM is taken out from the board, and the data on the production ROM is rewritten using dedicated equipment. , Remount on each board.
In such work, there is a problem that a trouble such as damage to the connector pin provided in the staging ROM occurs.
In response to such a problem, in the gaming machine of the present embodiment, the staging ROM is rewritten by accommodating the staging ROM in a cassette that is an external component for the staging board case and is removable from the staging board case. At this time, it is not necessary to open and close the board case, and it is not necessary to directly attach / detach the staging ROM to / from the board. Further, with the configuration described above, there is less possibility that stress is applied to the effect ROM and the connector extending from the effect board, so that there is no trouble of damaging the ROM or the effect board itself in the process of work.
In the gaming machine of the present embodiment, the efficiency and safety of the work associated with the rewriting of the production ROM can be dramatically improved. In addition, the reuse of the production ROM is promoted, and the manufacturing and development of the gaming machine can be remarkably streamlined while reducing the environmental load.

Moreover, in the present embodiment, since the programs and data used in the first effect board 50 and the second effect board 70 are integrated into one integrated ROM, the work of attaching and detaching the cassetteized ROM is performed only once. Therefore, it is possible to rewrite the ROM of the first effect board 50 and the second effect board 70 at once.
When removing the ROM cassette 40, it is only necessary to release the locking in the fastening locking portion 450B which has only the role of fixing (locking) the ROM cassette 40 to the staging board case 100, and it is only necessary to release the fastening locking portion. It is not necessary to release the locking of the 450B and open the staging board case 100.
In such an embodiment, it is possible to exchange the ROM in which the program for controlling the effect and the data are written with remarkably high efficiency as compared with the conventional case.

Further, conventionally, it has been necessary to release the fastening of the board case and open it only for replacing the removable parts (button batteries, etc.) in the staging board case.
However, in the present embodiment, the opening for accessing the button battery is provided in the cassette mounting portion, so that when the ROM cassette is mounted on the board case and fastened, the button battery can be accessed. It is possible to prevent unauthorized access to the inside of the board case through the opening, but on the other hand, simply removing the ROM cassette from the cassette mounting part exposes the opening for accessing the button battery and exposes the board case. You will be able to perform tasks such as replacing button batteries without opening the package.

Further, since the substrate base 100B does not have a connecting hole, the substrate base 100B is not locked by the caulking pin 125a. Therefore, as long as the locking of the caulking pin 123a in the fastening sealing portion 450A is released and the fastening cover 125d of the fastening locking portion 450B is removed, the ROM cassette 40 can be used as the effect board case without releasing the locking of the caulking pin 125a. The effect board case 100 can be opened while it is attached to the 100.

<Boot method of staging control CPU>
A method of starting the effect control CPU in the present embodiment will be described. As described above, the effect control CPU 71 integrates an image processor, an effect control CPU, and an image control CPU into one chip. The above-mentioned effect control ROM and effect control RAM may be built in.
Normally, such an effect control CPU is started by a boot program (boot program) stored in a low-capacity boot ROM (boot ROM).
However, there are concerns about the stable supply of low-capacity ROM used to store boot programs these days. Further, regarding the ROM, it is necessary to confirm the sum value of the stored data and guarantee that the data is not rewritten and that the ROM itself is not illegally exchanged, which is complicated.
Therefore, in the present embodiment, the start program is stored in the FeRAM (Ferroelectric Random Access Memory) 300, which is a non-volatile rewritable memory, and the effect control CPU 71 is started by executing the start program.
The FeRAM is a ferroelectric memory having a feature of high-speed operation. It is known that battery backup is not required for data retention, and it is superior in high-speed writing, high number of rewrites, and low power consumption as compared with EEPROM and flash memory.
By adopting FeRAM, which is a non-volatile RAM, there is an advantage that it is not necessary to use a low-capacity ROM which may be supplied, and since it is a RAM, it is not necessary to confirm the sum value.

<Write control for FeRAM>
As described above, FeRAM is a rewritable memory, and we want to use it not only for storing the startup program but also as an area for temporarily storing game information.
However, if data is erroneously written in the area in which the start program is stored in the FeRAM 300, the start program is destroyed and the staging control CPU 71 cannot be started.
Therefore, in the gaming machine of the present embodiment, data can be read and written to a part of the area of the FeRAM 300 by the process described below, and the area in which the start program of the staging control CPU 71 is stored is read-only. Is controlled so that it cannot be written.

FIG. 23 is a schematic diagram illustrating read / write control for the FeRAM of the present embodiment.
In the present embodiment, as shown in FIG. 23A, a regulation circuit 310 for restricting writing to the FeRAM 300 is provided between the staging control CPU 71 and the FeRAM 300.
The regulation circuit 310 is a circuit that permits or regulates writing to the FeRAM 300 by switching the write enable signal input to the FeRAM 300 according to the designated address of the write signal to the FeRAM 300 input from the staging control CPU 71.
The regulation circuit 310 has the configuration shown in FIG. 23B in detail, and the processing by the regulation circuit 310 will be described in detail later.
As shown in FIG. 23A, the FeRAM 300 includes a FeRAM array 300A composed of one or more FeRAM modules 301, and a controller 300B that controls the FeRAM module 301.
From the staging control CPU 71, 19 address lines connected to the address terminals A0 to A18 of the controller 300B are connected.

From the staging control CPU 71, an address signal of 0 or ¹ can be input to the address terminals A0 to A18 by each address line, and the address of 219 (5422 bits) can be specified for the FeRAM module 301. That is, the capacity of one FeRAM module 301 is 524288 bits.
In the case of the present embodiment, since the FeRAM array of the FeRAM 300 includes 16 FeRAM modules 301, the capacity of the entire FeRAM 300 is 219 × 16 = ^8388608 bits, that is, about 8 Mb.

At this time, as shown in FIG. 23C, 2Mb of the capacity of 8Mb is set as the read-only area 300a, and the remaining 6Mb is set as the read / write area 300b.
The start program (boot program) of the effect control CPU 71 is stored in the read-only area 300a, and the game information of the game machine 1 is temporarily stored in the read / write area 300b.
The read-only area 300a is realized by switching the input signal to the WB terminal of the controller 300B according to the address signal (input signal to the address terminals A0 to A18) designated to the FeRAM 300.
A part of the address signal designated by the staging control CPU 71 for the FeRAM 300, particularly the upper two bits (input signals for A18 and A17) are input to the regulation circuit 310. In order to specify the area of FeRAM 300 in Mbit units, the information of the upper 2 bits is sufficient.

FIG. 24 is a diagram showing an address in one FeRAM module.
As shown in FIG. 24, when the upper two bits (input signals for A18 and A17) of the address specified in the FeRAM 300 are 00, the combination of the input signals for the lower A16 to A0 causes ²¹⁷ = 131072 for one FeRAM module 301. The address can be specified, and the address of 217 × 16 = ^2097152 can be specified for the entire FeRAM array. That is, when the upper two bits of the address specified in the FeRAM 300 are 00, the address corresponding to the 2Mb area is specified. This area is controlled to be a read-only area 300a by the method described below.
Even when the upper 2 bits (input signals for A18 and A17) of the address specified in the FeRAM 300 are 01, 10 and 11, 217 × ¹⁶ = 209715 2 addresses are specified as in the case of 00 respectively, so that as a whole, 2, ¹⁷ × 16 × 3 = 6291456 addresses are specified. The remaining 6Mb area corresponding to these addresses becomes the read / write area 300b.

As shown in FIG. 23B, the regulation circuit 310 mainly consists of two OR gates and one NOT gate.
An input signal for A18 and an input signal for A17 (both 0 or 1) are input to the two inputs of the first OR gate 310a, respectively.
The output of the first OR gate 310a inverted by the NOT gate 310b and the WR signal from the effect control CPU 71 (0 indicates a write instruction and 1 indicates a read instruction) are input to the second OR gate 310c, and the output is input. It is input to the WB terminal of the FeRAM 300 as a write enable (WE) signal.

FIG. 25 is a diagram showing a truth table for explaining signal processing by the regulation circuit.
The processing of the regulation circuit 310 is performed as shown in FIG.
As shown in FIG. 25, when the upper two bits of the designated address for the FeRAM 300 are 00, as a result of the processing as shown in FIG. 25, the write enable signal, which is the output of the regulation circuit 310, becomes 1, and writing to the FeRAM 300 becomes impossible. .. The corresponding 2Mb area is a read-only area 300a.
In other words, the input signal that specifies 00 for the upper 2 bits b specifies the read-only area 300a, and in this case, the regulation circuit 310 restricts writing to the FeRAM 300.

When the upper two bits of the designated address for the FeRAM 300 are 10, 01, and 11, as a result of the processing as shown in the above table, the write enable signal, which is the output of the regulation circuit 310 at the time of writing (WR signal is 0), becomes 0, and the FeRAM 300 Can be written to. The corresponding 6Mb area is a readable / writable area 300b.
In other words, the input signal that specifies 00 for the upper 2 bits b specifies the read / write area 300b, and in this case, the regulation circuit 310 permits writing to the FeRAM 300.

The staging control CPU 71 does not consider the read-only area 300a and the read / write area 300b, and only inputs the address signal and the read / write signal to the FeRAM 300 (outputs to the FeRAM 300). Since the regulation circuit 310 permits or restricts writing to the FeRAM 300 according to the designated address, the read-only area 300a can be reliably set in the FeRAM 300. Therefore, by storing important data such as a start program of the staging control CPU 71 in the read-only area 300a, it is possible to prevent an accident in which the important data is overwritten and damaged.

If data is not written to a specific address of the FeRAM 300 by software processing by the effect control CPU 71, the above accident can be prevented when an incorrect address is specified due to noise due to static electricity on the board. However, it can be reliably prevented by the method of this embodiment.
In the above description, the WR signal from the staging control CPU 71 is input to the second OR gate 310c, but the output of the NOT gate 310b may be input to the FeRAM 300 as it is as a write enable signal without providing the second OR gate 310c. good. When setting the read-only area 300a, it can be said that it is not always necessary to distinguish between a read command and a write command.

The staging control CPU 71 may be started as follows.
As shown in FIG. 3, in the gaming machine of the present embodiment, the image display control for the image display device 31, the audio output control for the audio output device 34, the operation control of the staging accessory device 32, and the lighting of the staging lighting device 33. The staging control CPU 71 is configured to collectively perform control and the like.
Not limited to this, a lamp control CPU that controls the operation of the staging accessory device 32 and the lighting control of the staging lighting device 33 may be provided separately from the staging control CPU 71.
Then, when the game machine 1 is started, the lamp control CPU is controlled to start up earlier than the staging control CPU 71, and the lamp control CPU writes the boot program (startup program) of the staging control CPU 71 into the staging control RAM 56. The staging control CPU 71 is started by executing the boot program written in the staging control RAM 56.
By doing so, it is not necessary to provide a boot ROM for the staging control CPU 71.

At this time, the lamp control CPU can write data to the area where the boot program is written in the effect control RAM 56, but the effect control CPU 71 controls so that the data cannot be written.
For example, when a regulation circuit for restricting reading and writing to the staging control RAM 56 is provided and the write signal specifies a specific address of the staging control RAM 56 as in the case of the FeRAM described above (the high-order bit of the designated address is a predetermined value). In the case of), the writing of data is restricted. This makes it possible to avoid the risk of overwriting and damaging the boot program on the staging control RAM 56. When the write signal specifying a specific address is from the lamp control CPU, writing is permitted, but when the write signal is from the staging control CPU 71, the above configuration is realized by controlling so as to restrict writing. Can be done.

Next, the mounting mode of the components to be mounted on the board cover 100A of the staging board case 100 in the present embodiment will be described.
FIG. 26 is a diagram illustrating a component mounted on the staging board case, and is a view of the state of FIG. 12 as viewed from the front side. The heat sink cover is omitted.
As shown in FIG. 26, the heat sink 500 is screwed and fixed to the staging board case 100 from the inside (rear side) of the board cover 100A by screws 151 (first fixing means).
The board cover 100A includes a screw hole 118 for screwing with the screw 151.
The heat sink 500 is provided with an opening 501 for passing the screw 151.
The slide lock 550 is also screwed and fixed to the staging board case 100 from the inside (rear side) of the board cover 100A by screws 152 (first fixing means).
The slide lock 550 includes a screw hole 551 that is screwed into the screw 152.
The board cover 100A is provided with an opening 502 for passing the screw 152.

The heat sink 500 and the slide lock 550 are members that are not supposed to be removed from the staging board case 100 and replaced. Therefore, the effect board case 100 cannot be removed from the outside (front side).
When the heat sink 500 is removed by screwing from the outside (front side) of the board cover 100A and the screwing is released, the opening 103 (FIG. 12) of the staging board case 100 invades the inside of the staging board case 100. It leads to easy forgiveness. There is no point in sealing the staging board case 100 with the fastening sealing portion 450A (FIGS. 8 and 9), and there is a concern that fraudulent acts will be performed.
By fixing the heat sink 500 with screws from the inside (rear side) of the substrate cover 100A as shown in FIG. 24, such a concern can be eliminated.
Alternatively, the heat sink 500 and the slide lock 550 may be fitted to the staging board case 100. For example, the heat sink 500 may be fitted with an outer peripheral edge of the heat sink 500 into a groove provided on the inner peripheral surface of the opening 103, and may be further fixed by an adhesive.

On the other hand, as shown in FIGS. 8 and 12, the ROM cassette 40 is a member that is supposed to be attached to and detached from the effect board case 100. If the ROM cassette 40 is screwed from the inside (rear side) of the board cover 100A, the fastening sealing portion 450A (FIGS. 8 and 9) must be unsealed and the staging board case 100 must be opened. For this reason, the ROM cassette 40 cannot be removed from the staging board case 100.
Therefore, a member such as the ROM cassette 40, which is supposed to be attached / detached and replaced, is attached from the outside of the staging board case 100 and is a fastening sealing portion 450B (FIGS. 8 and 9) which is a second fixing means different from the screw. Fixes the board cover 100A from the outside (front side).

Next, an embodiment of removing static electricity from the surface of the staging substrate in this embodiment will be described.
FIG. 27 is a partially enlarged view of the first staging board housed in the board base as viewed from the front side.
FIG. 28 is a partially enlarged view of the substrate base accommodating the first staging substrate as viewed from the rear surface side.
FIG. 29 is a partially enlarged view of the first staging board as viewed from the rear surface side.
In order to ground the static electricity generated in the image display device (liquid crystal screen) installed on the front side of the staging board case 100, a metal plate (earth plate) 88 is placed on the front side of the staging board case 100 (board base 100B). It is equipped (Fig. 28).
As shown in FIG. 27, a ground wire 87 extends from the metal plate (earth plate) 88, and the ground wire 87 is connected to the connector 84 on the first staging board 55.
When the static electricity generated in the image display device or the like is collected on the first effect board 55 via the ground plate 88 and the ground wire 87, it is grounded (grounded) through a cable connected to a connector (not shown).

Further, in the present embodiment, the staging board case 100 for accommodating the staging control board 95 (first staging board 55, second staging board 70) is formed of a conductive carbon material.
As shown in FIG. 27, an electric contact 143 made of a conductive material, for example, a metal plate such as a copper plate, is provided around the opening 142 through which the screw 141 is passed on the front surface side of the first staging board 55. The screw 141 is formed of a conductive material, such as a conductive metal.
Further, as shown in FIG. 29, an electric contact 144 made of a conductive material, for example, a metal plate such as a copper plate, is provided around the opening 142 through which the screw 141 is passed on the rear surface side of the first staging board 55.
The first effect board 55 is installed in the effect board case 100, and the first effect board 55 is screwed into the effect board case 100 by passing the screw 141 through the opening 142.
The board cover 100A includes a screw hole 144 (FIGS. 11 and 26) for screwing with the screw 141.

The static electricity generated in the image display device (liquid crystal screen) and the like not only flows from the ground plate 88 to the ground wire 87, but also flows to the effect board case 100 made of the conductive carbon material and accumulates (charges). To go.
Then, the static electricity charged in the effect board case 100 flows to the surface of the first effect board 55 via the screw hole 144 of the effect board case 100 formed of the carbon material, the conductive screw 141, and the electrical contact 144, and is described above. Grounded (grounded) through a cable connected to a connector (not shown). By storing the static electricity in the effect board case 100 and then grounding it, the static electricity generated in the image display device (liquid crystal screen) or the like can be reliably grounded.
Instead of the screw 141, the first effect substrate 55 may be fixed in the effect substrate case 100 by a pin formed of a conductive material such as a conductive metal. In that case, the pin is passed through the opening 142, and the pin is fixed by the pin receiver provided on the board cover 100A.
Further, the first effect substrate 55 may be fixed in the effect substrate case 100 with a conductive adhesive. At that time, the adhesive is applied so as to come into contact with the electric contacts on the first staging substrate 55.
By providing a conductive pin or an adhesive between the electric contact on the first effect board 55 and the effect board case 100 made of the conductive material, the same effect as when the conductive screw 141 can be obtained can be obtained. ..

FIG. 30 is a modification of the configuration of FIG. 15, and the ROM cassette 40 accommodating the integrated ROM substrate 90 is also formed of a conductive carbon material.
In the integrated ROM board 90, in order to fix the integrated ROM board 90 to the cassette body 40B, an electric contact 94 made of a conductive material, for example, a metal plate such as a copper plate, is provided around the opening 93 through which the screw 95 is passed. The screw 95 is formed of a conductive material, such as a conductive metal.
The integrated ROM board 90 is installed in the cassette main body 40B, and the integrated ROM board 90 is screwed into the cassette case (cassette main body 40B) by passing the screw 95 through the opening 93.
At this time, the screw 95 is screwed into the screw hole 49 of the cassette body 40B.
The static electricity charged in the staging board case 100 is charged in the integrated ROM board 90 via the cassette body 40B formed of the carbon material, the screw holes 49, the conductive screws 95, and the copper plate (electrical contact) 94. Static electricity also flows through the cassette case 40A, and the entire ROM cassette 40 is charged.
The static electricity charged in the ROM cassette 40 flows to the surface of the first effect board 55 via the effect board case 100, the screw holes 144 of the effect board case 100, the conductive screws 141, and the electric contacts 144, and flows into the connector (not shown) described above. It is grounded through the connected cable.
By storing static electricity not only in the effect board case 100 but also in the ROM cassette 40 and then grounding, the static electricity generated in the image display device (liquid crystal screen) or the like can be reliably grounded.
Further, instead of the screw 95, the integrated ROM substrate 90 may be fixed to the cassette body 40B by a pin formed of a conductive material such as a conductive metal. In that case, the pin is passed through the opening 93, and the pin is fixed by the pin receiver provided in the cassette body 40B.
Further, the integrated ROM board 90 may be fixed to the cassette body 40B with a conductive adhesive. At that time, the adhesive is applied so as to come into contact with the electric contacts on the integrated ROM substrate 90.
By providing a conductive pin or an adhesive between the electric contact on the integrated ROM board 90 and the cassette case made of the conductive material, the same effect as when the conductive screw 95 is used can be obtained.

FIG. 31 is a diagram showing a staging board case in a state where a harness is attached to a connector of the first staging control board.
At a game store, a heat sink or a ROM cassette is attached to the effect board case 100 at the time of maintenance or cleaning of the game machine, and the effect control board 95 is removed from the main control board 50 for each effect control unit incorporated therein. Even when the content of the production is changed, it is exchanged with the manufacturer for each production control unit.
A harness 700 having one end connected to the connector 83 of the staging control board 95 extends from the opening 116 (FIG. 10) of the staging board case 100. The other end side extends to the main control board 50.
When the harness 700 is removed from the staging control board 95 and further removed from the main control board 50, it becomes difficult to know which side of the harness 700 should be attached to the connector 83. From the viewpoint of reuse, it is not desirable to frequently connect and disconnect the harness from the connector 83 of the staging control board 95.
It is desirable to handle the effect board unit (effect control board 95) with the harness 700 attached. Therefore, in the present embodiment, the connector cover 86 is provided near the opening 116 of the staging board case 100 so that the operator does not remove the harness from the connector 83 from the first staging board 55, and the same connector cover is mainly controlled. Not provided on the substrate 50 side.
