However, since the glass door frame is cantileveredly supported by the one side pivotal support in a cantilevered state, its position becomes very unstable when opened. Yes, even if it is touched, it will fluctuate. In particular, since each pachinko machine in the pachinko hall is installed with a certain tilt angle, the glass door frame may open to the fully open position and then naturally move toward the closed position by its own weight. . Therefore, when adjusting or cleaning nails on the game board surface with the glass door frame open, the glass door frame that tends to move to the closed position especially when working with both hands always touches the operator's shoulder or elbow. In some cases, the glass door frame has to be closed and locked, and then unlocked and opened again, which is an obstacle or a hindrance to the work, which makes the work very difficult and quick. However, if the glass door frame cannot be easily held at the position opened by a predetermined angle and released from that position, there is a risk that extra labor will be added and the work will be negatively performed quickly. Therefore, the present invention has been made to solve the above-mentioned problems, and has a simple structure, and furthermore, it is possible to easily hold and release the restraint at the fully opened position of the glass door frame, thereby stabilizing the open state. It is an object of the present invention to provide a pachinko machine that enables easy and quick adjustment of nails and cleaning of a game board to improve work efficiency.

[0004]

In order to achieve such an object, a pachinko machine of the present invention has a game board arranged on the rear side of a frame-shaped front frame having a window opening, and the window opening has an inner peripheral surface thereof. In a pachinko machine in which a glass door frame that is axially supported between a shaft support piece horizontally projected on one side part and an upper side part of an inner peripheral surface and covers the front surface of the game board is openably and closably attached, Engagement protrusions or engagement recesses are provided on the lower surface of the lower frame rod of the glass door frame and the upper surface of the shaft support piece so that the glass door frame engages with each other in a disengageable manner at a position opened by a predetermined angle. It becomes. Then, for example, when adjusting the nail of the game board surface, cleaning, or the like, the glass door frame is unlocked and opened by a predetermined angle, and the engaging convex portion and the engaging concave portion are engaged. As a result, the glass door frame is held at that position and does not change unnecessarily, and the work can be performed easily without being disturbed by the glass door frame. Further, after the work is completed, the glass door frame is moved in the closing direction to disengage the engagement convex portion and the engagement concave portion, and the glass door frame is closed as it is. In this way, no extra operation is required to hold or release the glass door frame in the so-called angular position.
