Description

[Detailed description of the invention] [Field of industrial application] The invention prevents pachinko balls from spilling out to the base frame side when opening the front plate to which the upper tray for storing pachinko balls is fixed. It is related to pachinko machines.

[Conventional technology]

Pachinko machines are widely used in which a front plate is attached to a base frame to which a game board is fixed so as to be openable and closable, and an upper plate is fixed to this front plate. Generally, the upper tray has the function of storing pachinko balls that are paid out as prize balls from a prize ball discharge port provided in the base frame, and also functions to feed the stored pachinko balls one by one to the firing device. There is.

By the way, a guide path has conventionally been used to guide pachinko balls paid out from the prize ball outlet on the base frame side to the upper tray. This guide path is fixed to the front plate, and when the front plate is closed, the entrance side of the guide path is connected to the prize ball outlet provided in the base frame, and pachinko balls from the prize ball outlet are connected to the guide path. is discharged from the outlet to the upper tray through the guide passage. However, if, for example, balls become clogged in the ball feeding passage connected to the upper tray, if the front plate is opened with the pachinko balls stored in the upper tray still in place, the balls will be released from the entrance side of the guiding passage. Pachinko balls may fall. To prevent this, it would be possible to remove and collect the pachinko balls stored in the upper tray, but this would be very troublesome and require removing the balls every time the front panel is opened. Ta.

To deal with this, for example,
