Description of the Related Art In a conventional pachinko ball, a launcher is attached to a lower end of a back surface of a wooden frame having a game board support frame mounted on the back surface thereof in a state of being separated from the game board support frame through a mounting plate or the like.

[0003]

When the launching device is attached to the wooden frame, the relative position between the launch rail base connected to the game board support frame through the set plate and the hitting hammer of the launching device is the pachinko machine base. However, there is a problem in that the work of correcting the deviation between the mounting position of the launch rail base and the mounting position of the hitting ball hammer becomes complicated. The present invention aims to solve the above problems.

[0004]

The structure for mounting the launching device in the pachinko machine of the present invention is such that the launch rail base is mounted on the front surface of the lower lateral frame portion of the game board support frame mounted on the back surface of the wooden frame. The set plate was integrally connected, and the hitting part of the hitting hammer of the launching device and the ball launching part of the launch rail base were aligned with the launching device set part formed at the lower end of the lower horizontal frame part. It has a configuration in which the launching devices are collectively attached in this state.

[0005]

[Operation] The set plate having the launch rail base attached to the front is coupled to the lower horizontal frame portion of the game board support frame, and the launcher is collectively mounted on the launcher set portion formed at the lower end of the lower horizontal frame portion. The launching rail base and the launching device are installed such that the relative position between the hitting part of the ball hitting hammer of the mounting and launching device and the ball launching part of the launching rail base is always in an appropriate state.

[0006]

Since the present invention is constructed as described above, when the game board support frame is mounted on the wooden frame, the relative positions of the ball launching portion of the launch rail base and the hitting portion of the hammer are always aligned. It is possible to install the launch rail base and the ball hitting hammer at predetermined positions in the state of being kept, and solve the problem that the relative position between the ball launching part of the launch rail base and the hitting part of the ball hitting hammer fluctuates between the pachinko machine bases. In addition to the above, there is an effect that the work of correcting the relative position between the launch rail base and the hitting hammer is unnecessary.
