In addition to this, not only the structure of the curve rail 102 itself is complicated, but also the number of parts is required, for example, by providing an opening 108, supporting the movable piece 109 in the opening 108, and installing the switch box 110. I was These back mechanisms are very complicated, and at present, they cannot meet the purpose of simplifying as much as possible and simplifying the assembling to improve workability.

Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to add a ball-break detecting function to a ball-pulling device, thereby eliminating the need for a ball-break detecting device and reducing the number of parts. By reducing the number, the structure of the curve rail is simplified, and as a result, the assembling is simplified and the workability is improved.

[0005]

In order to achieve the above object, a pachinko machine according to the present invention comprises a movable bottom plate which is axially attached to a ball hole provided in a ball passage of a curved rail, and is provided with an engaging lever. When the ball is disengaged from the pachinko ball, the pachinko ball that rides on the upper surface rotates downward to open the ball hole, and when there is no pachinko ball on the upper surface, it can rotate upward. The operation is detected by the electric detecting means, and the signal is sent to the winning ball processing device to stop the processing operation. As described above, by adding the ball-break detecting function to the ball-pulling device, the conventional ball-break detecting device becomes unnecessary, thereby reducing the number of components and simplifying the assembly and improving the workability.
