As shown in FIG. 18, in the second state, the cassette body 40B is closer to the locked portion 42 and the first fixed portion 43 inside the cassette case 40A.
The cassette case 40A includes a notch 48 near the first fixed portion 43 on the long side wall of the side including the first fixed portion 43 . The function of this notch portion 48 will be explained in detail below.

19 and 20 are diagrams for explaining the procedure for attaching the ROM cassette to the effect board case.
FIG. 19 illustrates 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 the ROM cassette 40 is attached.
In the cassette mounting part 104, the connector 81 of the production control board 55 included in the production board case 100, the positioning pin 105 for positioning the cassette body 40B, the claw part 110, and the first fixing part 111 are exposed. It is in.
In this state, the ROM cassette 40 is not attached to the effect board case 100, and the removable parts of the effect board case 100 (such as the button battery described above) can be accessed and removed.
Note that, as described above, the claw portion 110 protrudes downward with a space 110a between it and the surface of the cassette mounting portion 104, and fixes the second fixed portion 44 between the claw portion 110 and the surface of the cassette mounting portion 104. It is a member that

From this state, in FIG. 19(b), 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. 19(b), in the ROM cassette 40 in the first state, when the positioning pin 105 of the cassette mounting part 104 is inserted into the insertion hole 45 of the cassette body 40B, the claw part 110 of the board cover 100A is housed in the notch 48 of 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 production board case 100, completely connecting the connector 91 of the cassette body 40B and the connector 81 of the production control board 55. Can be connected. The first fixed part 43, the second fixed part 44 of the cassette case 40A, and the cassette main body 40B can all come into contact with the surface of the cassette mounting part 104 of the board 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 this embodiment, by simply pushing down the ROM cassette 40 straight down with the positioning pin 105 of the presentation board case 100 (cassette mounting portion 104) inserted into the insertion hole 45 of the cassette body 40B, the presentation board case 100 can be Since the connector 81 and the connector 91 of the ROM cassette 40 can be connected, there is no need to worry about damage due to unnecessary stress being applied to both connectors.
However, at this stage when the ROM cassette 40 is still in the first state, the position of the locked part 42 of the cassette case 40A does not match the position of the locked part 109 of the board cover 100A. Therefore, the ROM cassette 40 cannot be fastened (locked) to the production 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 is movable relative to the cassette body 40B.
That is, with the cassette main body 40B attached to the board cover 100A, the ROM cassette 40 can transition from the first state to the second state (FIG. 18).

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

The cassette case 40A is slid and finally the ROM cassette 40 is completely brought into the second state as shown in FIG. 19(d). At this time, the first fixed part 43 is completely inserted into the first fixed part 111 and fixed, and the tip 43a of the second fixed part 43 completely enters the space 110a below the claw part 110. Fixed.
Furthermore, since the position of the locked part 42 matches the position of the locked part 109 provided on the board cover 100A, the locked part 42 and the locked part 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 locking (fixing) member for locking (fixing) the ROM cassette 40 to the board cover 100A.

The state shown in FIG. 19(d) is an attached state in which the ROM cassette 40 is attached to the effect board case 100 regardless of whether the cassette case 40A is locked to the effect board case 100. In this state, removable parts (such as a button battery) of the effect board case 100 cannot be attached or detached.
In addition, in order to remove the ROM cassette 40 from the effect board case 100, the reverse procedure described in FIG. 19 may be performed. That is, after releasing the fastening between the locked part 42 and the locked part 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 fixation of the first fixed part 43 by the first fixing part 111 and the fixation of the second fixed part 43 by the claw part 110 are released, and as shown in FIG. 19(b).
By pulling out the ROM cassette 40, the ROM cassette 40 can be removed from the effect 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 and locked to the effect board case 100 when it is in the first state (FIG. 18). On the other hand, the ROM cassette 40 in the second state cannot be attached to the effect board case 100.

FIG. 20 illustrates 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 FIG. 19(a). If an attempt is made to attach the ROM cassette 40 in the second state to the cassette mounting portion 104 in this state, the state will be as shown in FIG. 20(b).
That is, as shown in FIG. 19(b), in the ROM cassette 40 in the first state, when trying to insert the positioning pin 105 of the cassette mounting part 104 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 such a way that the first fixed portion 43 of the cassette case 40A rides on the claw portion 110 of the cassette case 40A. 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 effect control board 55. The ROM cassette 40 is in a floating state above the surface of the cassette mounting portion 104 of the board cover 100A.
Although the position of the locked part 42 of the cassette case 40A and the position of the locked part 109 of the board cover 100A substantially match, since the ROM cassette 40 is floating above the surface of the cassette mounting part 104, The portion 42 and the locked portion 109 cannot be locked.
If the operator continues to forcefully push down the ROM cassette 40, there is a possibility that the cassette case 40A will be destroyed. However, the length of the positioning pin 105 provided in the cassette mounting part 104 is set to such a length 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 in the case as shown in FIG. Even if the ROM cassette 40 is forcibly pushed down, there is no fear that stress will be applied to both connectors and they will be 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 programs and data stored in the program ROM mounted on the production control board 50 and the data ROM mounted on the image control board 70.
Unseal and open the board case housing the production control board 50 and image control board 70, take out the production ROM from the board, rewrite the data on the production ROM using special equipment, and then reinstall it on the board.
In such work, there was a problem in that troubles such as damage to the connector pins provided in the performance ROM occurred.
To solve such problems, in the gaming machine of this embodiment, the performance ROM is housed in a cassette that is an external part to the performance board case and is removable from the performance board case, so that it is possible to rewrite the performance ROM. There is no need to open and close the board case, and there is no need to directly attach or detach the performance ROM to or from the board. Furthermore, with the configuration described above, there is little risk of stress being applied to the connectors extending from the performance ROM and the performance board, so there is no trouble of damaging the ROM or the performance board itself during the work process.
In the game machine of this embodiment, the efficiency and safety of work associated with rewriting the performance ROM can be dramatically improved. Furthermore, the reuse of the performance ROM is promoted, and the manufacturing and development of gaming machines can be made significantly more efficient while reducing the environmental load.

Moreover, in this embodiment, the programs and data used by the production control board 50 and the image control board 70 are integrated into one integrated ROM, so that by performing the work of removing and installing the cassette ROM only once, It is possible to rewrite the ROM regarding the production control board 50 and the image control board 70 at once.
When removing the ROM cassette 40, it is only necessary to release the locking in the fastening locking part 450B, which has only the role of fixing (locking) the ROM cassette 40 to the production board case 100, and the fastening locking part There is no need to release the lock at 450B and open the performance board case 100.
In this embodiment, the ROM in which programs and data for effect control are written can be exchanged with significantly higher efficiency than in the past.
