Accordingly, the movement of the security device main body 30 is restricted with respect to the fixing member 21 for attachment, and the crime prevention device main body 30 is attached to the fixing member 21 for attachment in a fixed state.

Next, an operation of removing the security device main body 30 from the mounting fixing member 21 so that the security device main body 30 is detached from the mounting fixing member 21 will be described with reference to the drawings. FIGS. 9-11 is an attachment operation | movement figure which shows the action | operation in removing the crime prevention apparatus main body 30 to the fixing member 21 for attachment. That is, FIG. 9 to FIG. 11 show a procedure for removal in a perspective view. In the drawings, the above-described appropriate members (the urging spring 52 are hidden and cannot be seen so that the operation can be easily understood. ) Is omitted. 9 is a first removal operation diagram, FIG. 10 is a second removal operation diagram, and FIG. 11 is a third removal operation diagram. 12 is a partial front sectional view of the state shown in FIG. 8, and FIG. 13 is a front view of the state shown in FIG.
The state before the detachment operation shown in FIGS. 9 to 11 is the state shown in FIG. 8 described above, that is, the state where the security device main body 30 is attached to the attachment fixing member 21. Further, the state after the detachment operation shown in FIGS. 9 to 11 is the state shown in FIG. 5 described above, that is, the state where the crime prevention device main body 30 is removed before being attached to the attachment fixing member 21.
9 to 13 is a key for rotating the cylinder lock 43a.

  First, in the first detachment operation diagram shown in FIGS. 9 and 13, the cylinder lock 43c is removed from the state shown in FIGS. 8 and 12 and the urging force of the urging spring 52 is removed. I am letting. Then, the cam 43b is interlocked with the removal rotation operation of the cylinder lock 43a, and a part that is difficult to see in the drawing comes into contact with a part of the removal member 51 to rotate the removal member 51. That is, the detaching member 51 located at the engagement position (FIGS. 8 and 12) with respect to the attachment fixing member 21 is brought into the engagement release position (FIGS. 9 and 13) with respect to the attachment fixing member 21. Will be located. As a result, the engaging portion 51b of the detaching member 51 is positioned so as to retreat from the mounting fixing member 21 side. Then, the vertical movement of the security device main body 30 with respect to the mounting fixing member 21 that has been regulated so far is permitted, and the security device main body 30 slides upward in the vertical direction with respect to the mounting fixing member 21. It becomes a state that can be made to.

In the second removal operation diagram shown in FIG. 10, the security device main body 30 is slid vertically upward with respect to the fixing member 21 for attachment. Thus, when the security device main body 30 is slid upward in the vertical direction with respect to the mounting fixing member 21, the guide of the security device main body 30 that has been fitted into the vertical fitting groove 24b of the mounting fixing member 21 until then. The fitting of the piece 51d is released, and the horizontal movement of the security device main body 30 with respect to the mounting fixing member 21 that has been regulated so far is permitted. Thereby, the crime prevention apparatus main body 30 will be in the state which can be slid to the horizontal separation direction with respect to the fixing member 21 for attachment.
In the third removal operation diagram shown in FIG. 11, the security device main body 30 is slid in the horizontal separation direction with respect to the mounting fixing member 21. When the security device main body 30 is slid in the horizontal separation direction with respect to the mounting fixing member 21 in this way, the security device main body 30 is detached from the mounting fixing member 21. When the cylinder lock 43c that has been removed and rotated from the state shown in FIG. 11 is returned to the original position, the state shown in FIG. 5, that is, the state before the security device main body 30 is attached to the attachment fixing member 21 is the same. It will be in the removed state.

According to the crime prevention device 20 of the slot machine 10, the following operational effects can be achieved.
That is, according to the crime prevention device 20 of the slot machine 10, the cylinder lock 43c is attached to the outer frame 11 side in the fixed state by the removal rotation operation different from the unlocking rotation operation. Since the frame 11 side is switched to a detachable removable state, the unlocking rotation operation for switching the stopper 41b from the restricted position to the permitted position, and the security device main body 30 can be detached from the outer frame 11 side. The removal rotation operation for switching to the state can be performed by one cylinder lock 43c.

Therefore, the removal work can be easily performed without the work of removing the screws.
Further, since the unlocking rotation operation and the detaching rotation operation can be performed by one cylinder lock 43c, it is possible to reduce the product cost without separately installing a locking device.
Since the cylinder lock 43c is the same as the cylinder lock 43c provided in the slot machine 10, the unlocking operation for unlocking the slot machine 10 itself and the crime prevention device 20 are unlocked. The unlocking rotation operation for removing the crime prevention device main body 30 from the slot machine 10 and the removing rotation operation for making the security device main body 30 removable can be performed with one key K. Therefore, the administrator of the slot machine 10 does not need to possess a plurality of keys, and the management burden can be reduced.

Since it is urged to change from the disengagement position to the engagement position, when the security device main body 30 is attached to the outer frame 11 side, this attachment state can be automatically maintained. As a result, according to the crime prevention device 30 of the slot machine 10, it is possible to easily perform the attaching operation without attaching a screw.
Further, according to the security device 20 of the slot machine 10, the security device main body 30 is fixedly attached to the outer frame 11 side via the mounting fixing member 21 fixedly attached to the outer frame 11 side. Thus, the cylinder lock 43c switches the crime prevention device main body 30 attached to the fixing member 21 in the fixed state to a detachable state in which the cylinder lock 43c can be removed from the fixing member 21 by the removal rotation operation. Therefore, while the security device main body 30 is a common component, the mounting fixing member 21 can be appropriately adjusted and changed according to the situation on the outer frame 11 side. As a result, the security device main body 30 can be used as a common component many times, leading to a reduction in product cost.
