A pachinko ball discharge device having a sphere control rotating body for controlling flow and having the following requirements (a) to (d).
(A) The ball supply path is formed in two rows on the upstream side.
(B) Two pairs of the claw wheels of the ball control rotating body are formed on the same axis corresponding to the number of rows of the ball supply paths, and the number of engaging claws of each claw wheel is three.
(C) When each claw wheel is rotated integrally and the angle between adjacent claw wheels is shifted by 60 degrees, when the engaging claw of one claw wheel is in a Y-shape, the other claw wheel is The engaging claws are in a reverse Y-shape.
(D) When the engaging claw of one claw wheel is in a Y-shaped state, the pachinko ball is received between the back and the abdomen of the engaging claw, and at that time, the engaging claw of the other claw wheel is in an inverted Y-shaped state. The pachinko ball is received with one engaging claw.
It is.

Therefore, since the balls up to the claw wheel on the ball supply path are arranged directly below, the weight of the plurality of balls is added to the claw wheel, so that a relatively large stepping motor is required and the discharge ball number command is not relevant. There is a drawback that even if the sensor for counting the number of paid-out balls is activated, it is difficult to determine that the processing is illegal.
Patent No. 3760772

    In view of the above-described conventional drawbacks, the present invention prevents the weights of a plurality of balls from being applied straight to the first and second ball receiving members, and if the stepping motor is driven illegally, An object of the present invention is to provide a ball dispensing device that can be discovered accurately and more quickly.

Since a stepping motor with a built-in position detection sensor is used, if the stepping motor is illegally driven or the first and second ball bearing members are illegally rotated, it can be easily detected. it can.
Therefore, fraud can be easily found.

(3) According to the above (1), since the stepping motor incorporating the payout position detection sensor is used in the main body, the stepping motor is hardly affected by disturbance and can be detected with high accuracy, and the dead space in the stepping motor Can be effectively utilized, and it is not necessary to separately provide a position detection sensor outside, so that the ball dispensing device can be miniaturized.

(4) In claim 2, the same effects as in the above (1) and (2) can be obtained, and fraud can be detected more accurately and promptly by the abnormal signal issuing device.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the present invention shown in the drawings.

  In the best mode for carrying out the present invention shown in FIGS. 1 to 11, reference numeral 1 denotes a ball dispensing device according to the present invention provided between a ball supply channel 2 and a ball dispensing channel 3. The ball dispensing device 1 has a case body 4 and an upper portion provided on the inner wall surface of the case body 4 formed in two rows vertically by a partition wall 5 communicating with the ball supply flow path 2, closer to the upper portion than the center portion. The first and second sphere supply path forming plates 6 and 7 are formed in such a manner that the portion is bent in a square shape and formed in two rows by the partition wall 5 so that one sphere can pass vertically at the lower end. The first and second ball supply passages 8 and 9 and the pair of guide pieces 10 and 10 and the lower portions of the first and second ball supply passages 8 and 9 bent in a square shape, etc. Three ball stoppers 11, 11, 11 and ball feeders 12, 12, 12 formed at intervals are formed, and each is shifted by 60 degrees. The first and second ball receiving members 13 and 14 and the first and second ball receiving members 13 and 14 are rotationally driven in units of 60 degrees in accordance with a payout ball number command. A stepping motor housed in the stepping motor chamber 4a of the case body 4 having a payout position detection sensor 16 with a signal output synchronized with the timing at which the balls are discharged from the two ball receiving members 13 and 14. 17 and a ball passage detection switch 18 for detecting a passing sphere provided in the case body 4b of a portion where one sphere downstream of the first and second sphere supply paths 8, 9 passes vertically. It is composed of

The payout position detection sensor 16 incorporated in the stepping motor 17 is a sensor part through which light passes through a recess 16a provided on the substrate 19 concentrically with the rotary shaft 15 on the stator side 20 inside the stepping motor 17. The optical sensor 24 and a rotor 22 that covers the entire optical sensor 24 and has an uneven portion 21 as a detecting portion that passes through the recessed portion 16a.
For this reason, since the payout position detection sensor 16 is disposed inside the rotor 22, it can be detected with high accuracy without being easily affected by disturbance, and the dead space in the stepping motor 17 can be effectively utilized. In addition, since it is not necessary to separately provide the position detection sensor 16 outside, the ball dispensing device 1 can be reduced in size.

The ball dispensing device 1 having the above configuration guides the sphere from the sphere supply flow path 2 to the first and second sphere supply paths 8 and 9, and the upper portions of the first and second sphere supply paths 8 and 9 are 2. The first part and the second ball receiving member 13, 14 are positioned in the lower part of the column that is perpendicular to the center and closer to the upper part than the central part, and is bent into the lower part. -One ball guided to the second ball receiving members 13 and 14 is located at the ball stoppers 11 and 11 or the ball feeding portions 12 and 12 of the first and second ball receiving members 13 and 14, and Since the sphere is located on the curved surface portion bent in a square shape and is not in a state of pressing the previous sphere directly by its own weight, a large load is applied to the first and second ball receiving members 13 and 14. Therefore, a relatively small stepping motor 17 can be used.

Further, the number of balls paid out by the stepping motor 17 can be detected by the payout position detection sensor 16 provided inside the stepping motor 17.
Accordingly, the payout position detection sensor 16 provided inside the stepping motor 17 performs payout processing (rotation control of the stepping motor) for the number of payout balls while confirming the signal in response to the payout ball number command.
On the sphere passage detection switch 18 side, it is confirmed whether or not the spheres corresponding to the number of commands have passed (discharged). If it is insufficient, a payout command is sent again for the shortage and the same operation is performed.

The payout position detection sensor 16 provided in the stepping motor 17 is effective for detecting (monitoring) an illegal operation. For example, the sensor signal is changed even though no operation command is issued. In such a case, fraud processing can be found from the judgment that it has been activated by an external factor.
