This invention relates to a power-free counting mechanism for an automatic ball lending machine that lends out a fixed amount of pachinko balls.

t (Prior art): Traditionally, this type of automatic ball lending machine has mainly been self-help ball lending machines that use electrical means such as solenoids, relays, and microswitches. In order to save labor and provide services to customers, pachinko ball rental machines were installed between pachinko machines and incorporated into the pachinko ball supply system, allowing pachinko balls to be rented out at nearby locations. It has become.

However, in order to eliminate the problem of space and the various drawbacks caused by electrical means when installing a pachinko ball lending machine, an automatic ball lending machine without a power supply was devised. Such shortcomings were pointed out. In other words, the first condition is to accurately count the number of balls according to the coins inserted, and the machine must rely on an electric type with an operating end and an energizing means such as a weight. However, there were naturally differences in the performance of the formula, and these requirements could not be met.

(Problems to be Solved by the Invention) The present invention is an automatic ball lending machine having a purely mechanical configuration without using any electrical means, and which can accurately count the number of balls for the inserted coins and at the same time. A powerless automatic ball lending machine with a novel configuration consisting of a cam-equipped sprocket wheel, a coin repeating lever, and a starting lever, all of which have the main parts consolidated to eliminate malfunctions and failures when continuously inserting coins. The purpose is to provide a counting mechanism (
Means for Solving the Problems) The power-free counting mechanism of the automatic ball lending machine of the present invention consists of a disk that engages pachinko balls supplied to a ball passage and counts their revolutions, and a disk that faces the coin passage and that rotates when the coins collide with the coins. The activation lever is provided with an engaging pin that rotates by pressing down on the connecting part and at the same time rotates the next coin by the weight of the moored coin, and the disc has an engaging step on its surface. A sprocket wheel with a cam is formed with cams cut out on the inside and outside, and when not in operation, the engagement pawl of the repeating lever engages with the engagement stage of the inner cam, and also when not in operation, the engagement claw of the activation lever is engaged. B/ is configured to engage with the engagement stage of the outer cam.

(Function) The inserted coin pushes down the inclined collision part of the repeating lever, and resists the urging force in the direction of disengaging the engaging pawl that was engaged when not in operation from the engaging stepped part of the inner cam. As it rotates, the next coin that is continuously inserted is moored to the coin locking step.

The coin that presses down the coin-contacting part of the continuous throw lever depresses the abutting part of the activation lever located directly below it. The engagement pin of the activation lever rotates against the restoring force of the balance weight in a direction that disengages it from the engagement stage of the outer cam groove that was engaged during non-operation, releasing the restraint of the cam-equipped sprocket wheel. do.

The cam-equipped sprocket wheel starts rotating under the load of the pachinko balls supplied to the ball path, rotates once, and is restrained again, while the cam-equipped sprocket wheel counts and discharges the pachinko balls.

The number of balls equivalent to one coin is determined by the number of teeth on the sprocket wheel.
