Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball payout device in a pachinko gaming machine that pays out a desired number of pachinko balls by rotating a lead screw.
[0002]
[Prior art]
There have been various forms of ball payout devices in pachinko gaming machines, and there are also devices configured to rotate the lead screw by a pulse motor and control the number of rotations to pay out the desired number of pachinko balls. One of them.
[0003]
By the way, generally, the ball payout device of the pachinko gaming machine is generally configured so that ball moving baskets are provided in two rows so that a large number of pachinko balls can be paid out in a short time so that winnings can be concentrated. .
[0004]
Therefore, in the conventional ball dispensing device, it is necessary to provide a ball sensor such as a proximity sensor for counting pachinko balls and an optical sensor for each ball moving basket. However, when a plurality of sensors are provided, there are problems such as high cost and complicated signal processing.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention is intended to solve the above-mentioned problems by making it possible to detect pachinko balls in two rows of ball moving rods with a single ball sensor.
[0006]
[Means for Solving the Problems]
For this purpose, the ball payout device in the pachinko gaming machine of the present invention has a conical lead screw with a sharp tip and a thread that can capture the pachinko ball on the outer periphery, and a rotation centered on the base end of the lead screw. By providing a shaft, the lead screw is vertically supported so that the tip thereof is at the bottom, and the lead screw is driven to rotate by the rotary shaft , and the outer periphery of the lead screw is positioned symmetrically on both sides of the lead screw. A pair of slanted ball moving rods formed along the surface, a payout rod that joins pachinko balls that have flowed down from both ball moving rods into one row by forming at the lower ends of both ball moving rods, It is characterized by comprising a single ball sensor that detects pachinko balls that flow down by being provided on the dispensing basket.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
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 pointed tip, and a rotation shaft 3 is provided at the base end portion thereof, and the lead screw is supported by a pulse motor 2 so as to be rotationally driven in the direction of an arrow. On the outer periphery of the lead screw 1, a thread 4 that can capture the pachinko ball p is formed. Reference numeral 5 denotes a plastic case formed around the lead screw 1, and the case 5 is formed with a pair of inclined ball moving rods 6a and 6b along the outer peripheral surface of the lead screw. Then, at the lower ends of the both ball moving rods 6a and 6b, a dispensing rod 7 is formed which joins the pachinko balls p flowing down from the both ball moving rods in one row, and the pachinko balls p flowing down to the dispensing rod 7 are detected. One sphere sensor 8 such as a proximity switch or an optical sensor is provided. In the passages 9a and 9b formed above the ball moving rods 6a and 6b, the pachinko balls p are lined up from the premium ball tank (not shown) in a line through the rectifying rods and flow down under their own weight.
[0008]
The rotation and stop of the pulse motor 2 are controlled by a ball delivery control circuit (not shown), and by rotating the lead screw 1, the pachinko balls in both ball moving rods 6 a and 6 b are caused to flow down, and through the dispensing rod 7, it becomes a prize ball dispensing rod. Let it drain. Then, the pachinko ball p passing through the payout basket 7 operates the ball sensor 8 and 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 p. Can be discharged into a prize ball payout basket.
[0009]
Since the two ball moving rods 6a and 6b are provided at the symmetrical positions on both sides of the lead screw 1 as described above, the pachinko balls p flow down the two ball moving rods 6a and 6b alternately. There is no possibility that the balls will overlap at the dispensing basket 7, and there is no possibility that the balls will bite at this junction. Further, the lead screw 1 is formed in a conical shape, and the both ball moving rods 6a and 6b are formed in an inclined shape along the outer peripheral surface of the lead screw. Therefore, detection by the sphere sensor 8 is also performed without error.
[0010]
【The invention's effect】
As described above, the ball payout device for the pachinko gaming machine according to the present invention provides a rotation shaft at the base end portion of the conical lead screw so that the lead screw is rotated by the pulse motor, and the lead screw. A pair of inclined ball moving rods along the outer peripheral surface of the lead screw are formed on both sides of the ball screw, and a payout rod that joins pachinko balls flowing down from both ball moving rods into one row at the lower ends of both ball moving rods. Since one ball sensor that detects and detects the pachinko sphere is provided in the payout basket, the pachinko sphere flowing down both the ball moving baskets can be counted with only one ball sensor, and a plurality of ball sensors are provided. As a result, the manufacturing cost is reduced and signal processing is facilitated.
