Abstract

PROBLEM TO BE SOLVED: To count pachinko balls passing through each ball displacement gutter, in a ball dispensing device dispensing the pachinko balls through the rotation of lead screws, simply by setting only one ball sensor even if the ball displacement gutters are arranged in two lines, thus making the manufacturing cost of the device lower than it is if a plurality of ball sensors are set, and facilitating signal processing. SOLUTION: A pair of lead screws 1a, 1b are vertically supported in such a way as to be rotated by a pulse motor 2, and two lines of ball displacement gutters 7a, 7b are formed between the lead screws. A dispensing gutter 9 by which pachinko balls (p) flowing down from each ball displacement gutter are merged into one line is formed at the lower end of each ball displacement gutter and one ball sensor 10 for detecting the pachinko balls is set in the dispensing gutter.

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 supports a pair of lead screws vertically so as to be rotated by a pulse motor, and two rows of lead screws are provided between the lead screws. Forming a ball moving gutter, forming a payout gutter at the lower end of the two ball moving gutters to join pachinko balls flowing down from the two ball moving gutters in a row, and detecting one ball at the payout gutter. A container is provided. Further, the present invention provides the ball dispensing device, wherein a pair of lead screws are connected to the pulse motor 2 via a gear so that the phase of rotation is shifted by 180 degrees, so that the pachinko balls alternately pass from both ball moving troughs to the dispensing gutter. It is characterized by flowing down. Further, the present invention is characterized in that in the above-mentioned ball dispensing device, a communicating portion between the two ball moving gutters and the dispensing gutter is formed stepwise for both the ball moving gutters.

[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 numerals 1a and 1b denote a pair of rotatable lead screws vertically provided in a plastic case 4, and 2 denotes a pulse motor for rotating the lead screws, which are fixed to the upper end of each lead screw shaft. The gears 3a and 3b are meshed with a gear 5 fixed to the rotation shaft of the pulse motor 2. The lead screw 1 has a thread 6 formed on an outer periphery thereof, which can capture a pachinko ball p.

Further, both lead screws 1 of the case 4
Two rows of ball moving gutters 7a and 7b are formed adjacent to each other with a partition wall 8 between a and 1b, and the pachinko balls flowing down from the two ball moving gutters merge into one row at the lower ends of the two ball moving gutters. A discharge gutter 9 is formed, and a pachinko ball p flowing down to the discharge gutter is formed.
Is provided with one ball sensor 10 such as a proximity switch or an optical sensor for detecting the occupancy.

The passage 1 is located above the ball moving gutters 7a and 7b.
1a and 11b are bent in a crank shape, and the pachinko balls p are arranged in a line from a prize ball tank (not shown) through a straightening gutter and flow down under their own weight into each passage.

[0010] As shown in FIG.
The communication portions 12a and 12b between the a and b and the dispensing gutter 9 are formed stepwise, so that when the pachinko balls flowing down from the two ball moving gutters 7a and 7b join the dispensing gutter 9, the two pachinko balls collide and collide. It is possible to avoid the risk of biting.

The rotation and stop of the pulse motor 2 are controlled by a ball payout control circuit (not shown).
a and 1b are rotated so that the two ball moving gutters 7a and 7
The pachinko ball in b is caused to flow down and discharged through the payout gutter 9 to the premium ball payout gutter. The pachinko balls p passing through the payout gutter 9 actuate the ball detector 10 and an electric signal thereof is input to the ball payout control circuit, and the rotation of the pulse motor 2 is controlled, so that a predetermined number of pachinko balls p. Can be discharged to a prize ball payout gutter.

The two ball moving gutters 7a and 7b can be formed adjacent to each other with the partition 8 interposed therebetween as described above, and the phase of rotation of the two lead screws 1a and 1b rotated by the pulse motor 2 is changed. By adjusting the meshing between the gears 3a, 3b and the gear 5 in advance so as to always shift by 180 degrees, the pachinko balls flow down from the two ball moving gutters 7a, 7b alternately. Although there is little possibility of overlapping, as described above, the communication portions 12a, 1
By forming the step 2b at a different level, it is possible to more reliably avoid the possibility that the ball may bite in this portion.

[0013]

As described above, the ball dispensing device for a pachinko game machine according to the present invention vertically supports a pair of lead screws so as to be rotated by a pulse motor, and moves two rows of balls between the lead screws. A gutter is formed, and a payout gutter is formed at the lower end of the two ball moving gutters to join the pachinko balls flowing down from the two ball moving gutters in one row, and one ball detector for detecting the pachinko ball in the payout gutter is provided. Since it is provided, it is possible to count pachinko balls flowing down both ball moving gutters with only one ball sensor, and it is possible to reduce the manufacturing cost and provide easier signal processing than providing multiple ball sensors. effective.
