DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotary winning device according to the present invention is used for a game machine (pachinko machine) having a well-known configuration, and will be described with reference to FIG. A winning device 20 is arranged substantially at the center of the gaming area 10 of the pachinko machine, and an operating port 7 is arranged at a lower left portion of the winning device 20. The winning device 20 includes a pair of opening / closing claws 21, a distributing rotator 22, and a distributing device 30.

[0007] A symbol display (two 7-segment displays) 11 for displaying a "winning symbol" and a "missing symbol" is provided above the winning device 20. , A rotary winning device (also referred to as a starting winning device) 50 described in detail below is disposed, and a large winning opening 90 having an opening / closing door 90a is provided below the rotary winning device. The pachinko machine is provided with a ball supply tray 2, a ball storage plate 3, a firing handle 4, and the like under the ball supply tray. The ball that does not win is ejected from the outlet 5.

The opening / closing claw 21 provided on the top of the winning device 20 keeps the open state by the electromagnetic solenoid for 2 seconds, for example, when the game ball wins the operating port 7. The game ball with the opening / closing claw 21 being opened is detected by a specific winning detector (proximity switch type or the like) provided below the opening / closing claw 21 and guided to the distribution rotating body 22. The disk-shaped distribution rotator 22 is always rotated by a motor (a stepping motor or the like), and the distribution rotator 22 is formed with six concave receiving portions 23. A game ball that has entered one receiving unit (V receiving unit) is detected by a determination detector (proximity switch type) and guided to the distribution device 30.

When the determination detector detects a game ball, a lottery is performed. At the time of a big hit, the game ball is guided to a specific area via the distribution device 30, and the specific ball detects the game ball. "Rights" occur. On the other hand, when the lottery is lost, the game ball is guided to the normal area, and when the game ball is detected by the normal detector, a predetermined number of prize balls are paid out as winning balls.

In the lottery, as is well known, for example, a circulation counter of 0 to 9 (1 is added every 2 ms) is created by software, and a game ball is detected by a determination detector. When the value of the circulation counter is, for example,
It is a hit when “7 (probability 1/10)”. Then, the result is fixedly displayed on the symbol display 11 after the symbols (0 to 9) are variably displayed. For example, when the hit determination display is “7, 7”, first, “7” is stopped and displayed in the left digit after a predetermined time, and then “7” is displayed in the right digit. In the case of a departure, the symbol display 11 displays different symbols on the left and right.

Then, the "right" is generated, and thereafter,
Until this right is extinguished, when the start detecting device 60 attached to the starting discharge path 71 formed in the starting winning device 50 installed on the right portion of the winning device 20 detects the big winning opening 90,
It is opened for a predetermined time or until a predetermined number of winning balls are present, so that a large amount of prize balls can be obtained.

Next, the configuration of the starting winning device 50 will be described with reference to the general view shown in FIG. 2A, the component parts diagram shown in FIG. 2B, and FIG. A hole 51a through which the rotator 52 is inserted is formed in the egg-shaped flat substrate 51, and a starting discharge path 71 is formed below the hole 51a, and a starting detector 60 is attached in the middle thereof. An insertion hole 57 is formed. A support body 59 for supporting a motor (such as a pulse motor) 56 is integrally formed on the top of the substrate 51 toward the back side. Also, on the top of a case body 53 covering the front surface of the base body 51 and the periphery of the rotating body 52,
An entrance 58 for guiding a game ball to a rotating body 52 to be described later is formed. The case body 53 is fixed from the back side of the base body 51 by screws (not shown) or the like. Further, a lamp board 54 is attached to a lower rear portion of the base 51, and is turned on and off by the control device to notify a game state.

A main magnet (permanent magnet) 55a is attached to a rotating shaft 56a of a pulse motor 56 vertically mounted on a support 59. On the other hand, a sub-magnet (permanent magnet) 55b is attached to the rotating body 52 having a cylindrical U-shaped ball receiving portion 52a so that the rotational power of the main magnet 55a can be transmitted. Therefore, the rotation of the pulse motor 56 is
Power is transmitted through the attraction force of the main magnet 55a and the sub magnet 55b to rotate the rotating body 52. The U-shaped tip of the ball receiving portion 52a has a round shape so that the game balls can smoothly fall on the ball receiving portion, and is formed at a depth at which one game ball can be stopped. is there. The main magnet 5
The 5a and the sub-magnet 55b are provided at positions that do not affect game balls (made of metal) stopped at the ball receiving portion 52a.

Next, the operation of the start winning device 50 having the above configuration will be described with reference to FIGS. 4 (A), 4 (B), 4 (C) and 4 (D). Continuous game balls Ya, Yb are the starting winning device 50.
The ball receiving portion 5 of the rotating body 52 that is rotating
When 2a reaches the top, the game ball Ya falls to the ball receiving portion 52a. Then, the rotating body 52 further rotates, and the ball receiving section 52
The game ball a falls into the starting discharge path 71, and the starting detector 60
Is detected by The detection signal of the start detector 60 performs a process such as a big hit. On the other hand, the subsequent game ball Yb maintains the state of being placed on the rotating body 52, and enters the ball receiving section 52a when the ball receiving section 52a comes, and the game ball Yb is detected by the rotation of the rotating body. And a process such as a jackpot is performed.

When the game ball Ya is sandwiched between the case 53 and the U-shaped ball receiving portion 52a as shown in FIG. 6A, the rotation of the rotating body 52 becomes impossible. Since it is configured to be rotatable via the attractive force of the main magnet 55a and the sub-magnet 55b, only the pulse motor 56 and the main magnet 55a rotate, and failures such as burning of the pulse motor 56 can be prevented.

In the above-described configuration, both the main magnet 55a and the sub-magnet 55b are formed of magnets. However, power may be transmitted by magnets on one side and objects that can be attracted on the other side. In the case, since the spinning body 52 is free to rotate smoothly and the rotating body 52 is easy to be free, the game ball is dropped on the ball receiving portion 52a due to vibration or the like, and the game can be continued.

Next, FIGS. 5A and 5B show another structure for transmitting the rotation of the pulse motor 56 to the rotating body 52. FIG. 5A is a sectional view, and FIG. Four inclined claws 81 are inserted into the rotation shaft 56 a of the pulse motor 56 and inserted into the inner periphery of the cylindrical coupling body 80 in a protruding state via a spring 83 fixed by a plug 82. is there. On the other hand, the insertion body 84 attached to the rear part of the rotating body 52 is housed in the connecting body 80, and the claws 81
And tightly bonded. Therefore, the rotation of the pulse motor 56 rotates the rotating body 52 via the connecting body 80 and the inserting body 84.

However, even if the rotating body 52 becomes unrotatable, the connecting body 80 is subjected to a rotating torque by the pulse motor 56, and the rotating torque presses the claw 81 to compress the spring 83. Can be.
That is, the claw 81 acts as a torque limiter,
Even if the rotating body 52 becomes unrotatable, the pulse motor 56 can rotate, so that a failure such as burning can be prevented. In addition, the connecting body 80 is aside from the pulse motor 56 side,
It may be attached to the rotating body 52 side, and the resilience of the spring 83 is selected in consideration of the rotating torque of the rotating body 52 and the like.

As described above, the rotating body 52 for receiving the game ball can easily transmit the rotational torque via the magnet and the torque limiter even if the game ball bites and cannot rotate. Furthermore, since power transmission can be cut off, failure of the pulse motor can be prevented. The starting winning device 50 has a configuration in which a game ball is dropped on a rotating body from an entrance formed at the top,
The game ball may be formed so as to receive the game ball falling obliquely from above from the diagonally upper part on the rotating body. In this case, the load on the rotating body is reduced by the continuous game ball. In addition, the rotary winning device having the rotating body 52 is not limited to the starting winning device 50, but can be applied to the distribution rotating body 22 and other similar winning devices.
