Open 4
By removing the stopper 29, the sprocket 5 rotates due to the weight of the ball to supply the ball to the ball storage tank 3, and
The large and small gears 27 and 28 rotate to count the supply of balls. For example, when 100 balls are supplied, the large gear 28 makes one rotation and the stopper 29 operates to stop the sprocket 25. ing.

[Problems to be solved by the device]

However, since the above-mentioned conventional one does not detect the balls to be supplied, it is necessary to form the ball flow passages 4 which are inclined for a long distance in order to smoothly arrange and supply the balls in the flow passages. Moreover, the ball flow passage 4 is detected by detecting the opening of the pachinko front plate 2b.
Since the bulky closing lever 10 for closing the above is provided, installing these devices in a narrowly limited island for pachinko machine installation makes the installation work extremely troublesome and may cause a failure. Moreover, the number of balls to be thrown out is determined by a fixed gear ratio, so that an arbitrary number of balls cannot be supplied.

Therefore, the present invention has been made in order to solve the above-mentioned problems of the conventional technology, and detects and counts balls, and detects the opening of the pachinko board surface to supply the balls. It is to provide a small and inexpensive device in which the whole device can be installed compactly on the pachinko machine installation island and the supply amount of balls can be set arbitrarily.

[Means for Solving the Problems]

As a means for achieving this, the present invention rotatably arranges a sprocket having projecting ball engaging teeth in a ball flow passage between a ball supply trough and a ball storage tank of a pachinko machine, and the ball engaging teeth by a spring. A stopper biased to the locked state, and an electromagnet that operates the stopper in the disengagement direction from the ball engaging teeth are attached, and a sensor for detecting the presence or absence of a ball blocked by the sprocket is installed in the ball flow passage, A sensor for detecting the opening of the pachinko machine is provided, and the electromagnet circuit is controlled to be opened and closed by both sensors.

〔Example〕

The configuration of the present invention will be described in detail below with reference to an embodiment shown in the drawings.

Reference numeral 1 is a ball supply gutter, 2 is a pachinko machine, and a pachinko front plate 2b is attached to the front side of the frame 2a so as to be openable and closable by a hinge or the like, and a ball storage tank 3 is provided above the back surface of the pachinko front plate 2b. A ball flow passage 4 is provided between the ball supply gutter 1 and the ball supply gutter 1. These structures are constructed in the same structure as the conventional one.

In this invention, a ball cutting device 5 is attached between the ball flow passages 4. Reference numeral 7 denotes a sprocket, which is rotatably attached to the case body 6 of the ball cutting device 5 and has ball engaging teeth 8 formed on the outer periphery of the sprocket 7 for communicating with the ball flow passage 4 and a ball inflow passage 9 and a ball outflow passage. The sprocket 7 is projected so as to rotate by coming into contact with a falling ball passing between 10 and 10. Reference numeral 11 is an electromagnet, which is mounted in the case body 6 by a mounting bracket 12, and a stopper 13 is arranged so as to face the electromagnet 11 so as to be attractable, and an upper portion of the stopper 13 is a protruding piece of the mounting bracket 12. The lower end of the stopper 13 is pivotally attached to the sprocket 7, and the lower end of the sprocket 7 is releasably engaged with the ball engaging tooth 8 of the sprocket 7. The ball 13 is constantly urged in the direction of locking the ball locking tooth 8. Reference numeral 15 denotes a door opening detection sensor made up of a micro switch, which is attached to the lower surface of the case body 6, and a switch lever 15a of the door opening detection sensor 15 is arranged so as to be able to come into contact with and separate from the back surface of the pachinko front plate 2b.

Reference numeral 16 is a ball presence / absence detection sensor, and 17 is a ball counting sensor. The ball presence / absence detection sensor 16 is attached to the ball inflow passage 9 side with the sprocket 7 interposed, and the ball counting sensor 17 is attached to the ball outflow passage 10 side. There is.

Operation of the open door detection sensor 15 and ball presence / absence detection sensor
The operation of 16 is configured to operate the electromagnet 11 via an AND circuit (not shown).

With this configuration, when the balls are supplied to the ball storage tank 3 of the pachinko machine, a ball output command switch (not shown) is turned on as shown in the flow chart of FIG.
At this time, the pachinko front plate 2b is closed, the switch lever 15a of the door opening detection sensor 15 is in the ON state, the ball is flowing down into the ball inflow passage 9 of the ball-slicing device 5, and the ball presence / absence detection sensor 16 is ON.
In the state, the AND circuit is turned on, the electromagnet 11 is excited, the stopper 13 is attracted against the tension of the spring 14, disengages from the ball engaging teeth 8 of the sprocket 7, and the sprocket 7
Is in a free state, so the balls in the ball inflow passage 9 moored therein flow down to the ball outflow passage 10 side, are dropped and stored in the ball storage tank 3 of the pachinko machine 2, and the electromagnet 11 is caused by the flow of this ball. Is demagnetized to release the attraction force to the stopper 13, the tip of the stopper 13 is locked by the ball engaging tooth 8 of the sprocket 7 by the tension of the spring 14, and the rotation of the sprocket is stopped. Therefore, the balls in the ball inflow passage 9 are prevented from falling toward the ball outflow passage 10 by the ball engaging teeth 8 of the sprocket 7. Then, the flow of the ball is counted by the ball counting sensor 17, and when it reaches a predetermined number, the ball output command switch is turned off.
The replenishment is completed.

When the pachinko front plate 2b is in the open state for repairing or inspecting when replenishing the balls, the switch lever 15a of the door opening detection sensor 15 is in the OFF state, and the ball inflow path 9 is not replenished. Unless the ball presence / absence detection sensor 16 is in the OFF state and both circuits are not in the ON state, the electromagnet 11 is demagnetized by the AND circuit, the sprocket 7 is locked, and the balls are not supplied.

[Effect of device]

As described above in detail with reference to the embodiments, the present invention has a compact size by accommodating the electromagnet and the sprocket mechanism that operates by this and stops the supply of balls in the ball-slicing device. In addition to being compactly installed, the number of balls to be supplied can be freely changed to a desired number.

Furthermore, the front plate is opened due to the operation of the ball presence / absence detection sensor or the pachinko machine failure / repair / inspection, etc. even when the ball is not supplied to the ball supply gutter or the ball inflow path or the ball intermittently flows in. When the door-opening detection sensor operates while the ball is being turned on, the beating device stops the ball supply, so the balls are reliably counted and supplied, and the balls do not drop out of the ball storage tank. It is possible to provide a robust and inexpensive ball-slicing device such as that supplied to the.
