[0002]
[Prior art]
As a locking device that prevents the front frame hinged to the outer frame so that it can be opened to the outer frame with respect to the outer frame that covers the outer periphery of the gaming machine, The lock plate member is provided so as to be movable up and down or pivoted substantially orthogonally to the lock plate, and the lock member provided on the outer frame is releasably engaged with the collar member provided on the lock plate member. Thus, there is known a configuration in which the front frame can be opened by the release.
[0003]
FIG. 11 is a side view of the upper end portion of the conventional locking device having the above configuration. In this conventional locking device, first hooks 42 are integrally provided on the upper and lower ends of the first lock plate 41, respectively. Therefore, a wire W having rigidity such as a piano wire is inserted from a gap between the outer frame F ₁ and the ball lending device of the adjacent gaming machine, and the hooking portion Wa at the tip of the wire W is When the wire W is hooked on the engaging portion 42a of the first collar piece 42 and pulled downward or obliquely downward, a pair of first collar pieces 42 are formed on the upper and lower ends as shown by solid lines in FIG. The integrally formed first lock plate 41 slides downward, and the engagement between the lock piece 43 provided on the outer frame F ₁ and the first hook piece 42 is released, and the lock device is illegal. Is unlocked.
[0004]
As a result, the front frame F ₂ is opened with respect to the outer frame F ₁ , and the control board box on the back side of the game board mounted on the front frame F ₂ is replaced with another one, or the illegal board is used for wiring. Fraudulent behavior (commonly referred to in the industry as “gotting”) is performed.

An object of the present invention is to prevent a locking device that locks a front frame with respect to an outer frame from preventing the locking device from being unlocked by an unauthorized operation and opening the front frame with a simple structure. .
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the invention described in claim 1 includes a rectangular frame-shaped outer frame, a front frame hinged to the front side of the outer frame so as to be able to be opened in one side, and a front side of the front frame. In a gaming machine comprising a glass frame hinged so that it can be opened in a single-sided manner, it can be locked and disengaged with respect to the locking pieces fixed to the upper and lower parts inside the vertical frame material on the anti-hinge connection side of the outer frame. Therefore, it is attached to a mounting plate fixed to the rear side of the opening edge of the front frame on the anti-hinge connection side so as to be movable up and down, and is always biased and held in the upward engagement direction by the first tension spring. A first lock plate that can be moved downward in the unlocking direction by an unlocking operation, and an upper portion and a lower portion of the first lock plate, respectively , projecting integrally in a backward direction, With each downward movement, an engagement posture position and a non-engagement posture position with respect to the lock piece A first locking device having first displaceable first hook pieces, and a rearward projecting rearward side of the glass frame at a predetermined interval on the rear side of the open edge of the glass frame on the anti-hinge connection side; In order to detachably engage with a plurality of second flanges that can be inserted into the first insertion holes formed in the first projection hole and protrude rearward of the mounting plate, the first mounting hole is movably mounted on the mounting plate. The glass frame is closed with respect to the front frame, and the second rod pieces are inserted and engaged with the same number of second insertion holes formed at the same interval as the plurality of second rod pieces. The second tension spring and the second insertion hole are engaged with each other by moving in an upward unlocking direction by an unlocking operation in a state in which the second tension spring is constantly biased downward to maintain And a second locking device having a second locking plate configured to be unlocked by being released An upper end portion of a first lock plate constituting the first lock device is detachably engaged with an upper end portion of a second collar piece disposed at an uppermost position among the plurality of second collar pieces. Engagement release stop pieces that can be combined are integrally formed, and each second flange piece of the glass frame closed with respect to the front frame is inserted into and engaged with each second insertion hole of the second lock plate. In the locked state, the disengagement restraining piece is disposed at a position where it can engage with the upper end of the uppermost first flange piece, the front frame is closed with respect to the outer frame, and the front In each locked state where the glass frame is closed with respect to the frame, the first hook piece engaged with the lock piece is pulled down by a wire illegally inserted into the inside from the outer frame and illegally unlocked. When this is the case, the disengagement restraining piece of the first lock plate engages with the upper end of the second collar piece of the second lock device and The first lock plate and the first hook piece are configured to be prevented from moving in the unlocking direction.
[0008]
According to the first aspect of the present invention, when the opened front frame is first closed with respect to the outer frame, the upper end surfaces of the upper and lower first hook pieces constituting the first lock device are under the lock pieces facing each other. By sliding against the edge, the front frame approaches the outer frame while moving downward in the unlocking direction of the first lock plate against the urging force of the first tension spring, and the first frame By engaging the hook piece and the lock piece, both the first lock plate and the first hook piece are returned to their original locking positions and locked by the urging force of the first tension spring. In this locked state, the disengagement stop piece at the upper end of the first lock plate is in a position where it does not interfere (engagement collision) with the second collar piece constituting the second lock device.
Further, in the above-described front frame locking state, when the opened glass frame is closed with respect to the front frame, a plurality of second hooks constituting the second lock device are respectively inserted into the second insertion holes of the second lock plate. The glass frame is closed and locked with respect to the front frame which is inserted and passed through the upper end portion of the second hook piece engaged with the upper end of the second insertion hole and closed and locked to the outer frame. . Note that, in this glass frame locking state, the distal end portion of the second collar piece protruding rearward of the second locking plate is non-interfering (non-engaging) with the lower side of the disengagement stopping stopping piece constituting the first locking device. ) State, and in the locked state, the distal end portion of the second collar piece is disposed immediately below the disengagement stop piece.
[0009]
On the other hand, when the front frame is opened, even if the first lock piece is lowered to the unlocking position together with the first lock plate by an unlocking operation using an appropriate key, the disengagement stopping stop piece of the first lock plate. However, it cannot engage with the second hook piece of the second locking device located below and cannot descend. For this reason, assuming that the glass frame is opened first, the second insertion hole is moved to the upper position of the second hook piece by moving the second lock plate to the unlocked position by the unlocking operation using an appropriate key. Since the engagement between the second lock plate and the second collar piece is released and unlocked at the time of transition to, the glass frame can be opened so as to be pulled out forward with respect to the front frame. In the opened state of the glass frame, since the second collar piece does not exist immediately below the disengagement stop piece of the first lock plate, the first lock plate is allowed to move downward.
Then, after the above-described opening of the glass frame, the first lock plate is lowered together with the first lock plate by lowering the first lock plate to the unlock position by an unlocking operation using an appropriate key. Since it is shifted downward and separated from the lock piece, it can be opened so that the front frame is pulled out to the front side with respect to the outer frame. In this unlocking operation, the disengagement restraining piece naturally goes down together with the first lock plate without interfering with the second hook piece of the second locking device.
[0010]
As described above, the front frame and the glass frame can be locked and unlocked. In the invention according to claim 1, the front frame and the glass frame are closed and locked with respect to the outer frame and the front frame, respectively. When a wire such as a piano wire that has entered the back side of the outer frame as a locking operation is hooked on the first hook piece and the first hook piece is moved in a downward unlocking direction to be detached from the lock piece. Since the disengagement restraining piece of the first lock plate engages with the upper end of the second hook piece and prevents the first lock plate and the first hook piece from descending, the first hook piece is separated from the lock piece. The engagement and disengagement is impossible, and unauthorized unlocking using the wire is prevented in advance.
