a cannot be opened. As shown in FIG. 14, since the fixed portion 513 and the fixing portion 514 are formed on the side surface of the pachinko gaming machine 1, there is an advantage that the aesthetic appearance of the pachinko gaming machine 1 is not impaired.

FIG. 15 shows a fifth embodiment. The box-shaped outer frame 504 in the fifth embodiment has the same shape and material as the box-shaped outer frame 503b shown in FIG. The difference from the fourth embodiment is that the main control board box 87b, the lamp control board box 220, the audio control board box 221, and the payout control board box 222 are mounted on the inner wall surface of the rearward bulging portion 551. That is the point. It is desirable that the control boards housed in the respective control board boxes be arranged with the chip mounting surface side facing the mounting surface. By doing so, the chip mounting surface of the control board can be seen through from the rear side of the box-shaped outer frame 504 made of a transparent synthetic resin,
It is possible to easily find traces of unauthorized modification such as replacement of a chip. The soldering surface opposite to the chip mounting surface may be provided facing the mounting surface. In this manner, the mounting surface can be visually recognized by opening the front frame 1a, and the solder surface can be visually recognized from the outside even in the closed state. In addition, by attaching the control board box to the rearward bulging portion 551, the control board in the control board box is provided at a position as far away from the mechanism plate 53 as possible, resulting from static electricity generated on the mechanism board. There is an advantage that the adverse effect of noise hardly reaches the control board. Further, by attaching each control board box to the inner wall surface of the bulging portion 551 via a metal plate, it is possible to further prevent adverse effects due to noise. Further, if the metal plate is grounded with a ground wire, the effect becomes more remarkable.

FIG. 16 shows a sixth embodiment.
In the sixth embodiment, the front frame 521a and the box-shaped outer frame 521b are locked by a plurality of types of keys, instead of being fixed by the fixing portion 211 and the fixed portion 212 described above. Specifically, in addition to a locking device that locks a front frame and a glass frame used in a game arcade that has existed conventionally, locking and unlocking can be performed using a key or the like different from the locking device. Provide a locking device. Then, during the transportation from the gaming machine maker to the transportation of the gaming machine, the front frame 521a and the box-shaped outer frame 521b are closed, and the locking device 519 is locked by the locking piece 520 (locked state). State). This lock device 519
The key for releasing the locked state of the game is to be held only by a public agency such as the police, a game machine maker, or an owner of a game arcade. In the case of handing over to a game arcade, it is to be handed over after delivery of the pachinko gaming machine 1. Then, after the pachinko gaming machine 1 is carried into the game arcade, the key for the lock device 519 is inserted into the keyhole 518 and unlocked, whereby the lock device 519 and the locking piece 52
The lock with 0 is released. The pachinko gaming machine 1 is shipped from a gaming machine maker in a state where the locking device 519 is locked, and the locking device 519 is unlocked after the pachinko gaming machine 1 is carried into a game arcade. Machine 1
It suffices if at least the lock state is reached during the transportation, but the owner of the amusement arcade may lock the game hall after the business is closed. Note that during business hours at the game arcade, the lock device 519 is unlocked without being locked by the conventional lock device 2.
Lock at 33.

The key and lock device 519 is not limited to the one described above.
As described in Japanese Unexamined Patent Publication, the lock device has a function of storing a key that can be unlocked and locked, and when the key is changed, the changed key is stored in the lock device.
Locking and unlocking can be performed with the stored key. A so-called variable lock device may be used. Furthermore, a password is input from the input key, and the password is collated and the password is unlocked if the password is correct. , Or unlocking when the fingerprint matches and the fingerprints match. The above-mentioned variable lock device may be used to enhance security during the transportation of the pachinko gaming machine. For example, the front frame 1a of a pachinko game machine has one lock device (variable lock device), and can be unlocked only by a key given to a game machine manufacturer or a hall owner or a public agency at the time of shipment. After setting, the delivery is unlocked with the key, and then the setting is changed so that it can be unlocked with a normal key held by a store clerk of the game arcade. The key is unlocked while the game arcade is open. In this manner, security during transportation by one lock device can be enhanced. Alternatively, a plurality of lock devices of the same type may be provided so that each can be unlocked with a different key.

With the structure as in the sixth embodiment,
Even if the key to release the front frame and glass frame, which has been used in the amusement arcade, is stolen and the key is used to unlock the card while the pachinko machine is being transported, the key alone will not unlock. It cannot be unlocked unless a public key such as the police, a game machine maker, or the owner of the game arcade performs the unlocking operation with a key possessed by the owner. As a result, security during the transportation of the pachinko gaming machine 1 can be improved. Furthermore, if the owner of the amusement park owns the key, it is highly likely that the owner is involved in the fraud, so that it becomes easier to identify the culprit.
