The above-mentioned objects are attained by the present invention. According to the first aspect of the present invention, the unauthorized unlocking mechanism is provided between the unlocking member and the engaging claw, and the unlocking member moves when the unlocking member moves from the locking position to the unlocking position. The movement is transmitted to all the engagement claws, and the movement of the engagement claw when the engagement claw moves from the locked position to the unlocked position alone is not transmitted to the unlocking member. For this reason, even if one engaging claw is moved from the locked position to the unlocked position using a special tool, the other engaging claws are held in the locked position by the elastic member. Therefore, the pachinko machine frame cannot be opened only by illegally unlocking one of the engaging claws. That is, since it becomes difficult for fraudulent acts to be materialized, the crime prevention function of the pachinko machine is improved. Note that one frame may be a machine frame and the other frame may be a table frame, or one frame may be a table frame and the other frame may be a machine frame. Further, one frame may be a front frame and the other frame may be a gold frame, or vice versa.

According to the second aspect of the present invention, the unauthorized unlocking mechanism is formed by engaging the pin with the long hole, and when the unlocking member moves from the locked position to the unlocked position, the pin and the long hole are prevented. The position relationship between the pin and the long hole is set in a state where there is almost no play between
When one of the engagement claws moves from the locked position to the unlocked position, the movement of the one engagement claw is prevented from being transmitted to the unlocking member in a state where play exists between the pin and the elongated hole. The positional relationship between the pin and the slot is set. That is, since the unauthorized unlocking prevention mechanism can be constituted by the pin and the long hole, the structure of the unauthorized unlocking preventing mechanism is simplified.

According to the third aspect of the present invention, since the lock member for locking the engaging claw at the locking position is provided, the engaging claw cannot be illegally moved from the locking position to the unlocking position. For this reason, it is difficult for fraudulent acts to be materialized, and the security function of the pachinko machine is improved. When the unlocking member moves from the locking position to the unlocking position, the unlocking transmission mechanism transmits the movement of the unlocking member to the locking member to release the locked state, and then controls the movement of the unlocking member. Inform the engaging claw.

That is, the lock claw 56 of the lock lever 50 is displaced from the step 33d of the upper engagement claw 30 and disposed on an extension of the circular arc portion 33e, so that the lock of the upper engagement claw 30 is released.

Next, the inclined surface 26 of the upper engaging claw 30 comes into contact with the receiving member 7 of the machine frame 2 from below, and the inclined surface 26 of the engaging claw 30 slides following the receiving member 7. While the inclined surface 26 is sliding with respect to the receiving member 7, the upper engaging claw 30 pivots downward around the support pin 21 while pulling up the upper movable lock plate 60 against the spring force of the lower spring 66s. I do. When the concave portion 22 of the upper engaging claw 30 reaches the position of the receiving bracket 7, the upper engaging claw 30 is moved upward by the spring force of the lower spring 66s to engage with the receiving bracket 7 of the machine frame 2. I do.

Lock 0. The lower engagement claw 20 is also hooked on the receiving metal 7 of the machine frame 2 in the same procedure as the engagement claw 20 of the first embodiment. As a result, the front frame 3 is locked to the machine frame 2.

To unlock the front frame 3, the cylinder lock 18 is operated by an unlock key (not shown), and the unlock lever end 19 is rotated upward to a predetermined position. When the unlocking lever end 19 is rotated upward, the unlocking lever end 19 causes the upper movable lock plate 60 and the lower movable lock plate 66 to rotate.
Moves upward against the spring force of the lower spring 66s. Since the connection pin 64 of the upper movable lock plate 60 is in contact with the upper end of the upper long hole 66n of the lower movable lock plate 66 by the action of the lower spring 66s, the upper movable lock plate 60 is raised by the cylinder lock 18. By being moved, the lower movable lock plate 66 moves upward integrally with the upper movable lock plate 60.

When the upper movable lock plate 60 and the lower movable lock plate 66 move upward, the upper movable lock plate 60 first rises with respect to the upper engaging claw 30 by the size of the upper slot 61. As a result, the step-shaped pressing portion 62 of the upper movable lock plate 60 pushes up the lock claw 56 of the lock lever 50 by a predetermined size, and the lock claw 56 is held on the extension of the arc portion 33e of the upper engagement claw 30. The lock of the upper engagement claw 30 is released.
Further, when the upper movable lock plate 60 and the lower movable lock plate 66 continue to move upward from this state, the upper engagement claw 30 and the lower engagement claw 20 rotate downward around the support pin 21 to unlock. Will be When the upper engaging claw 30 starts rotating, the step-shaped pressing portion 62 comes off the lock claw 56. Here, the unlocking can be performed even if the upper movable locking plate 60 and the lower movable locking plate 66 are directly moved upward by an unlocking handle (not shown).

Next, the operation of the lock device when the lower engaging claw 20 is illegally rotated will be described. As shown in FIG. 8, in a state where the front frame 3 is locked, for example, when the lower engagement claw 20 receives a force in the unlocking direction (downward) by a special tool, the rotation force of the lower engagement claw 20 Is transmitted to the lower movable lock plate 66, and the lower movable lock plate 66 moves upward against the spring force of the lower spring 66 s with the rotation of the lower engagement claw 20.
However, the lower movable lock plate 66 is connected to the upper movable lock plate 60 via the upper elongated hole 66n and the connection pin 64, and the upper elongated hole 66n of the lower movable lock plate 66 has an upper end corresponding to the connection pin 64. In contact. Therefore, the lower movable lock plate 6
Even if 6 moves upward, the connecting pin 64 only moves relatively downward inside the upper elongated hole 66n, and the movement of the lower movable lock plate 66 is not transmitted to the upper movable lock plate 60. Therefore, the upper movable lock plate 60 is kept at the lower limit position, and the upper engagement claw 30 does not move from the locked position. That is, even if the lower engaging claw 20 is unlocked improperly, since the upper engaging claw 30 is in the locked position, the front frame 3 is not opened.

Even if the upper engaging claw 30 is attempted to be unlocked illegally, the upper engaging claw 30 is locked by the lock claw 56 of the lock lever 50. It cannot be turned. Therefore, unauthorized opening of the front frame 3 can be prevented, and the security function of the pachinko machine is improved.
