Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine in which balls to be used for a game are stored and a saucer having an opening / closing opening for discharging these balls downward is projected on the front surface thereof. The present invention relates to a ball counting machine that counts the number of balls discharged from a payout opening.

[0002]

2. Description of the Related Art As a conventional ball counting machine, a receiving opening for receiving balls falling from a payout opening on the bottom of a tray of a gaming machine is fixedly installed by making a hole in a top plate on which the gaming machine is installed. There is something to do.

Further, in Japanese Patent Laid-Open No. 7-185122, a box-shaped ball counter having a ball receiving opening on its upper surface is movably mounted on a top plate on which a game machine is installed. Is disclosed. This ball counting machine is in the shape of an elongated box with an opening for receiving balls on its upper surface.
One end of the box-shaped ball counting machine in the longitudinal direction is supported by a rotary shaft provided on a top plate laterally removed from the front of the gaming machine, and is horizontally rotatable about this center. Has become.

In a normal state, the ball counter is in a state of being rotated in a horizontal direction parallel to the gaming machine, and its receiving port is set at a position just below the payout port on the bottom surface of the tray of the gaming machine. When the player opens the payout opening on the bottom of the tray, the balls stored in the saucer fall from the payout opening to the entrance of the ball counter, and the number of the balls is counted.

On the other hand, when the game machine is removed and replaced with a new one, the ball counter is rotated approximately 90 degrees to the front, and it is retracted from the front of the game machine. As a result, the ball counting machine does not become an obstacle to the replacement of the game machine, and the replacement work of the game machine can be efficiently performed.

This ball counting machine is equipped with a detecting means for detecting whether or not the ball receiving port is in a state of being rotated to a horizontal position directly below the saucer of the gaming machine. When it is rotated to a position other than the position, it warns that the ball may have fallen out of the entrance.

In addition, there is a ball counting machine in which a retractable bellows member is attached to the receiving port of the ball counting machine. The bellows member is manually extended and brought into close contact with the bottom surface of the saucer of the gaming machine. This prevents the balls discharged from the payout opening from falling into the receiving entrance.

Further, in order to prevent an illegal act such as adjusting an obstacle nail, the gaming machine itself is provided with a sensor for detecting whether or not the front door is opened, and an alarm is issued when the front door is opened. There is a game machine that does.

[0009]

However, in the case where the receiving port of the ball counting machine is directly mounted on the top plate, the portion protruding from the top plate becomes an obstacle, so the ball counting machine is replaced when the game machine is replaced. Had to be removed once, and there was a problem that replacement work took time and effort. Further, since the payout opening on the bottom surface of the tray of the game machine and the receiving opening of the ball counting machine are separated from each other, the balls discharged from the payout opening may be spilled to a place other than the receiving opening.

On the other hand, in the case where a ball counting machine having a receiving opening on the upper surface is rotatably mounted on the top plate, the ball counting can be performed at a position which does not hinder the replacement work of the gaming machine just by rotating it toward the front Since the machine can be retracted, the replacement work can be performed easily in a short time. However, like the one with a fixed entrance on the top,
Since the outlet and the inlet of the tray are separated, there is a risk that the balls discharged from the outlet may spill out of the portion other than the inlet.

In the case where a bellows member is provided at the receiving opening and is extended to the bottom of the receiving tray so as to be in close contact with the dispensing opening, it is possible to prevent spillage of balls other than at the receiving opening. However, every time the game machine is replaced, it is necessary to manually extend and contract the bellows member up and down to bring it into close contact with the bottom surface of the saucer, which causes a problem that the man-hours of the game machine replacement work increase accordingly.

When a sensor for detecting opening and closing of the front door of the gaming machine is provided in the gaming machine itself, every time the gaming machine is replaced, a signal line from the sensor is connected to an alarm device provided outside. There is a problem that it is necessary to re-do, and the replacement work of the game machine becomes complicated.

The present invention has been made by paying attention to the problems of the prior art as described above, and it is possible to replace the gaming machine without dropping the balls discharged downward from the tray of the gaming machine. It is an object of the present invention to provide a ball counting machine which does not cause an obstacle and can reduce the number of working steps.
