Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize ball discharging device for a pachinko machine which discharges a predetermined number of prize balls when a prize ball is generated.

[0002]

2. Description of the Related Art In a prize ball discharging device of this type, conventionally, a prize ball counting gutter capable of accommodating only a predetermined number is communicated with a prize ball replenishing gutter, and the gutter shakes around the axis as a winning ball occurs. A motion is generated, and a given amount of prize balls is discharged at each swing. By the way, with such a structure, the gutter becomes long in the width direction corresponding to the number of the prize balls, and therefore, the discharge position is limited and the supply members of the prize balls are limited in position.

Therefore, in order to improve this, a vertical counting trough communicating with the prize ball replenishing trough through a supply path, a rotatable downflow control valve facing the upper end opening of the counting trough, and the counting. A rotatable drop control valve that faces the lower end opening of the gutter, moves up and down along the counting gutter due to the occurrence of a prize ball, and alternately comes into contact with the flow-down control valve and the drop limiting valve to establish a predetermined value in the counting gutter. A prize ball discharging device has been proposed, which comprises a discharge actuating piece for discharging a number of prize balls. This product releases the predetermined number of prize balls in the counting trough by releasing the contact with the drop control valve due to the rise of the discharge operation piece, and the flow control valve to prevent the next prize ball from falling during that time. Blocks the upper opening of the counting gutter by abutting with,
At the same time as the completion of dropping of the predetermined number of prize balls, the lowering of the discharge actuating piece causes the lower end opening of the counting trough to be blocked by the contact with the drop control valve and the contact with the flow control valve to be released. The upper end opening is blocked and released at an appropriate timing.

[0004]

The discharge actuating piece is for contacting the downflow control valve or the drop control valve to restrict the rotation of the downflow control valve or the drop control valve. For this reason, when the discharge actuating piece moves up and down, frictional resistance is generated at the contact portion with the downflow control valve or the drop control valve. On the other hand, the drive control of the discharge actuating piece is desired to use an electric drive source in order to perform it positively due to the occurrence of winning balls. However, with an electric drive source such as an electric motor,
When the discharge actuating piece is forcibly moved up and down, the frictional resistance at the abutting portion becomes remarkable. And as a result,
A large amount of force is required to raise and lower the discharge actuating piece, which deteriorates its operability, and rather hinders the smooth release of prize balls due to the occurrence of winning balls, which shortens the useful life of the discharge actuating piece. There was fear. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a prize ball discharging device capable of positively and smoothly discharging a prize ball.

[0005]

In order to achieve the above object, in the present invention, a vertical counting trough communicating with a prize ball replenishing trough through a supply path and an upper end opening of the counting trough are provided. A rotatable flow-down control valve, a rotatable drop control valve that faces the lower end opening of the counting trough, and a lift control valve that moves up and down along the counting trough due to the occurrence of winning balls and the flow-down control valve and the drop regulation. In a prize ball discharging device, which comprises a discharge actuating piece that alternately abuts a valve and discharges a predetermined number of prize balls in the counting trough, the discharge actuating piece is an electric drive source of the winning ball detection device. It is connected to an elevating rod that is raised by forcibly moving the prize balls by the driving force, and is between the release operating piece and the contact portion of the downflow control valve, or the contact between the release operating piece and the drop control valve. A contact roller is interposed between the contact section and the section. .

[0006]

[Function] When a winning ball is generated, the winning ball is forcibly moved by the driving force of the electric drive source of the winning ball detection device, and the discharge operation piece also rises with the rise of the elevating rod, and the drop control valve. And the flow control valve is closed, so that the prize ball in the counting trough is released from the restriction by the drop control valve and is released by a predetermined number. Next, as the prize balls are discharged, the lifting rod and the discharge actuating piece descend, causing the fall restricting valve to engage and the flow control valve to open, so that the prize ball flows into the counting trough. In this operation, the frictional resistance is reduced at the contact portion with the downflow control valve or the fall control valve in which the contact roller is interposed. Therefore, the discharge actuating piece can move up and down smoothly.
