Abstract

PROBLEM TO BE SOLVED: To reduce a manufacture cost compared to the case of setting a plurality of ball sensors and to facilitate a signal processing by counting pachinko balls passing through both ball moving gutters just by setting one ball sensor even when the two lines of the ball moving gutters are formed in a ball pay-out device for paying out the pachinko balls by the rotation of a lead screw. SOLUTION: A rotary shaft 3 is disposed on the base end part of a conical lead screw 1, the lead screw 1 is supported so as to be rotated by a pulse motor 2 and a pair of inclined ball moving gutters 6a and 6b along the outer peripheral surface of the lead screw 1 are formed on both sides of the lead screw 1. A pay-out gutter 7 for merging the pachinko balls (p) falling down from both ball moving gutters 6a and 6b into one line is formed at the lower end of both ball moving gutters 6a and 6b and the pay-out gutter 7 is provided with one ball sensor 8 for detecting the pachinko balls (p).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball dispensing device for a pachinko game machine that dispenses a desired number of pachinko balls by rotating a lead screw.

[0002]

2. Description of the Related Art Conventionally, there are various types of ball dispensing devices in pachinko game machines, in which a lead screw is rotated by a pulse motor and the number of rotations is controlled to pay out a predetermined number of pachinko balls. Is one of them.

Conventionally, a ball dispensing device of a pachinko game machine has been generally constructed so that ball moving gutters are provided in two rows so that a large number of pachinko balls can be dispensed in a short time and a prize can be concentrated. Have been.

Therefore, in the conventional ball dispensing device, it is necessary to provide a ball sensor such as a proximity sensor and an optical sensor for counting pachinko balls for each ball moving gutter. However, providing a plurality of sensors increases the cost and complicates signal processing.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is to solve the above-mentioned conventional problems by enabling a single ball detector to detect pachinko balls in two rows of ball moving gutters. It is.

[0006]

For this purpose, a ball dispensing device in a pachinko game machine according to the present invention is provided with a conical lead screw provided with a rotating shaft at a base end thereof so that the lead screw is rotated by a pulse motor. A pair of slanted ball moving gutters are formed on both sides of the lead screw along the outer peripheral surface of the lead screw, and pachinko balls flowing down from the two ball moving gutters are formed at the lower ends of the two ball moving gutters. A payout gutter to be joined to the row is formed, and the payout gutter is provided with one ball sensor for detecting a pachinko ball.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a conical lead screw having a sharp tip, and a rotating shaft 3 is provided at the base end thereof, and the lead screw is supported by a pulse motor 2 so as to be driven to rotate in the direction of the arrow. Lead screw 1
A screw thread 4 capable of catching the pachinko ball p is formed on the outer periphery of. Reference numeral 5 denotes a plastic case formed around the lead screw 1. The case 5 has a pair of inclined ball moving troughs 6 along the outer peripheral surface of the lead screw.
a, 6b are formed. Then, both ball moving gutters 6a, 6
At the lower end of b, a payout gutter 7 is formed to join the pachinko balls p flowing down from the two ball moving gutters into one row, and a proximity switch or an optical sensor for detecting the pachinko balls p flowing down to the payout gutter 7 is provided. One ball detector 8 is provided. The pachinko balls p flow down from the prize ball tank (not shown) in a line through a straightening gutter into the passages 9a and 9b formed above the ball moving gutters 6a and 6b under their own weight.

The rotation and the stop of the pulse motor 2 are controlled by a ball payout control circuit (not shown). By rotating the lead screw 1, the pachinko balls in the two ball moving gutters 6a and 6b flow down, and the prize ball passes through the payout gutter 7. Discharge to the discharge gutter. And the pachinko ball p passing through the payout gutter 7
When the ball sensor 8 is operated, its electric signal is input to the ball payout control circuit, and the rotation of the pulse motor 2 is controlled, whereby a predetermined number of pachinko balls can be discharged to the premium ball payout gutter.

Since the two ball moving gutters 6a and 6b are provided at symmetrical positions on both sides of the lead screw 1 as described above, the pachinko balls p flow down the two ball moving gutters 6a and 6b alternately. There is no danger that two pachinko balls will overlap at the payout gutter 7 and there is no danger of ball biting at this confluence. In addition, since the lead screw 1 is formed in a conical shape and the two ball moving gutters 6a and 6b are formed so as to be inclined along the outer peripheral surface of the lead screw, the pachinko ball may always smoothly merge and the pachinko ball may jump at the merging point. Therefore, detection by the ball detector 8 is also performed without error.

[0010]

As described above, in the ball dispensing device for a pachinko game machine according to the present invention, a rotation shaft is provided at the base end of a conical lead screw, and the lead screw is supported so as to be rotated by a pulse motor. At the same time, a pair of slanted ball moving gutters are formed on both sides of the lead screw along the outer peripheral surface of the lead screw, and pachinko balls flowing down from the two ball moving gutters are arranged in a row at the lower ends of the two ball moving gutters. A payout gutter to be joined is formed, and the payout gutter is provided with one ball sensor for detecting a pachinko ball, so that only one ball sensor can count pachinko balls flowing down both ball moving gutters, and a plurality of pachinko balls can be counted. The manufacturing cost is reduced as compared with the provision of the ball detector, and the signal processing is facilitated.
