BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine that is integrally formed with a transparent plate holding frame that is pivotally supported on a front surface of a front frame body and covers a front surface of a game board, and that is excellent in design and also prevents fraud. .
[0002]
[Prior art]
Generally, in a pachinko gaming machine, a front frame is disposed on the front surface of the machine frame. A game board is mounted on the rear surface of the front frame body, and a transparent plate holding frame that covers the front surface of the game board is disposed on the front surface. More specifically, the front frame is fixed to one side of the machine frame, and the transparent plate holding frame is fixed to the one side of the front frame so as to be freely opened and closed. Further, a cylinder lock for locking the front frame and the transparent plate holding frame is provided on the front surface on the open side of the front frame so as to protrude forward.
[0003]
On the other hand, recently, a pachinko gaming machine in which the horizontal width of the transparent plate holding frame is substantially the same as the width of the front frame body and covers the entire upper front surface of the front frame body has become mainstream. This is because the design on the front of the pachinko machine can be made novel and unified, and the product value is increased.
[0004]
By the way, in this kind of pachinko machine, the keyhole portion of the cylinder lock is usually provided on the front end surface, and the operation with the key is performed from the front side of the transparent plate holding frame. It is necessary to open a through hole in which the tip of the cylinder lock is inserted into the holding frame and the keyhole portion faces. However, since this through hole is located on the open side of the transparent plate holding frame and the transparent plate holding frame rotates around one side, the cylinder lock is supported so that the cylinder lock cannot be rotated. It must be molded larger than the outer diameter of the lock.
[0005]
However, if the size of the through hole is made much larger than the outer diameter of the cylinder lock in this way, a gap is created between them, and a thin wire is inserted through the gap, for example, by operating the cylinder lock originally, the front frame There is a risk of fraud by actuating a locking rod or locking plate that opens the body or the transparent plate holding frame. Therefore, the outer peripheral surface of the cylinder lock and the through hole are formed by molding the keyhole peripheral member that is the peripheral portion of the cylinder lock separately from the transparent plate holding frame, and fixing the keyhole peripheral member to the front frame. A gap is not generated between the two.
[0006]
[Problems to be solved by the invention]
As described above, the keyhole peripheral member, which is the peripheral part of the cylinder lock, is formed separately from the transparent plate holding frame, and the keyhole peripheral member is fixed to the front frame so that it is between the outer peripheral surface of the cylinder lock and the through hole. However, if the pachinko gaming machine is viewed from the front, the transparent plate holding frame and the area around the keyhole can be used. There is a problem that not only the boundary with the member appears clearly and it is difficult to integrate it in terms of design, but it is also inferior in appearance and the product value is lowered.
[0007]
Therefore, the present invention has been made to solve the above problems, and without forming a keyhole peripheral member separately as in the prior art, the entire transparent plate holding frame including the keyhole peripheral portion is integrally formed. To provide a pachinko machine that can improve the design of the transparent plate holding frame, improve the product value, and at the same time prevent fraud. It is the purpose.
[0008]
