For more details, see Economic fluctuations for 1 coin.
When the number of pachinko balls for each machine changes, it becomes necessary to immediately change the counting mechanism of the automatic pachinko ball lending machine to continue business activities without any hindrance. This paper relates to a rate conversion mechanism for pachinko ball rental machines to meet this demand.

(Prior art) The number of thin ball lending machines installed between each pachinko machine is almost the same as the number of pachinko machines, but due to economic changes, the number of balls dispensed per coin can be changed. teeth,
Various rate conversion mechanisms for pachinko ball rental machines have been proposed, such as a method of replacing an expensive counting mechanism, or a method of changing the number of rental balls by replacing a plurality of intermediate gears prepared in advance with different diameters.

(Problem to be Solved by the Invention) The method of replacing the expensive counting mechanism as described above is not a good idea. Furthermore, the method of replacing intermediate gears requires preparing a plurality of intermediate gears with different diameters in advance, and the time and man-hours required for the replacement work are also uneconomical. The present invention aims to solve the problems of the rate conversion mechanism of the conventional pachinko ball lending machine.

(Means for Solving the Problems) In order to achieve the above object, the mechanism for converting the ball lending machine into the ray 1 according to claim 1 comprises: a starting lever whose one end rotates downward by the weight of the inserted coin; The sprocket 1 hesi wheel rotates with the weight of the supplied pachinko balls and causes the pachinko balls to flow down, and the gear that constantly rotates in conjunction with the sprocket wheel engages with the activation lever and rotates the sprocket 1 to wheel to release the balls. During this period, the sprocket wheel is rotated through a main gear having a cam plate that prevents the starting lever from returning and maintains the rotation of the sprocket I wheel, and a lock lever connected to the other end of the starting lever. The pachinko ball rental machine is equipped with a stop pawl for controlling the sprocket wheel for rotating the balls, and the sprocket wheel for rotating the balls is integrally provided with a plurality of gears of different diameters and a rotating body having protrusions on the outer peripheral surface, and the gears of the different diameters An intermediate gear is provided which sets the number of rotations of the sprocket wheel for dispensing coins by meshing with one of the main gears and interlocking with the main gear.

The rail conversion mechanism of the pachinko ball rental machine according to claim 2 has a rail in which a plurality of pivot positions of the intermediate gear and pivot positions of the sprocket wheel and the main gear are appropriately arranged. A switching plate is provided, and when the current shaft support position of the intermediate gear disposed on the rate switching plate is replaced with another shaft support position, and the intermediate gear is meshed with the different diameter gear, a mechanism is configured that meshes with the main gear. This makes it possible to change the number of balls lent per coin inserted using the same intermediate gear.

(Function) When a coin is inserted, the activation lever is rotated, and the lock lever connected to this activation lever releases the stop pawl from the sprocket wheel, releasing the rotation stop and causing the pachinko balls to start flowing down. . Then, this state of doweling for coins is maintained while the main gear having a cam plate that engages with this activation lever rotates once, that is, while the sprocket wheel rotates for doweling for coins, and the coin dispensing is completed. Later, the activation lever is returned to its normal state and the lock lever is lowered to engage the stop pawl, thereby stopping the rotation of the sprocket wheel. The number of balls lent based on the coins thus inserted is determined by the number of balls flowing down per one rotation of the sprocket I-wheel and the number of rotations of the sprocket wheel per one rotation of the main gear.

In the mechanism of the present invention, the intermediate gear interlocked with the main gear is meshed with one of a plurality of different diameter gears integrally provided on the sprocket wheel, and the main gear rotates once by changing the engagement partner and the different diameter gear. The rotation speed of the sprocket wheel is changed to change the number of balls lent to the inserted coins, that is, the rail.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described based on the drawings. Note that in the following, a 100 yen coin will be used as a coin.

FIG. 1 is an internal configuration diagram of a pachingo ball rental machine according to the present invention,

A ball passage 12 is provided almost vertically near the player's side 10a, and the pamphlet balls flow down inside this ball passage 12 and are discharged from a ball outlet 14. This ball passage 12 is provided with a sprocket wheel 16 that rotates by engaging with the pachinko balls flowing down.

This sprocket wheel 16 is provided with ten locking portions 16a that engage one pamphlet ball at a time, and rotates once when ten pachinko balls flow down. By stopping the rotation of the sprocket wheel 16, the pachinko balls can be prevented from falling.

A coin passage 18 is formed on the back side 10b of the casing 10, and a coin sorting machine (not shown) judges whether the 100 yen coins inserted by the player are good or bad, and only proper 100 yen coins are accepted. A starting coin falling down the coin passage 18 with one end 20a protruding into the coin passage 18 and rotated downward by the weight of the fallen 100 yen coin is pivotally supported. One end of a lock lever 24 is connected to the other end 20b of the activation lever 20 across the rotation shaft 22, and a stop claw 26 is connected to the other end of the lock lever 24. This stop claw 26 rotates around a fulcrum shaft 26a and is driven by a drive pin 24a provided on the lock lever 24. That is, when the lock lever 24 moves upward, the rotating end 26b of the stop claw 26 moves upward (arrow 100).

In this way, the activation lever 20 is activated by inserting a 100 yen coin.
By the rotation of the sprocket wheel 16, the rotation of the sprocket wheel 16 is started, and ball dispensing is started. Then, by one rotation of the cam plate 36, the activation lever 20 is returned to the normal state, and the rotation of the sprocket wheel 16 by the lock lever 24 and the stop claw 26 is stopped, thereby completing the payout of 100 yen worth of balls.

In this embodiment, the locking portion 16a of the sprocket wheel 16
Since there are 10 pachinko balls, for example, if you want to release 25 pachinko balls for 110110100 yen, the intermediate gear 30 should be pivoted at the pivot position B1 of the rate switching plate 31 mentioned above. If supported, the sprocket I/wheel 16 will be supported by the cam plate 36.
It will make two and a half revolutions during each rotation. Also, if you want to release 20 pachinko balls for 100 yen, if you replace the intermediate gear from the shaft support 1iB1 to B2, the sprocket/wheel 16 will rotate twice while the cam plate 36 rotates once. Become.

That is, the rotation ratio data of the main gear and sprocket wheel by the toothed metal gear of this example is as follows.

The sprocket wheel 16 has a rotating body 2 that rotates integrally with the sprocket wheel 16.
