DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball sending device which sends a pachinko ball by rotating a rotating body with a plurality of ball passages through which the ball flows down, and rotating the rotating body with a motor.

[0002]

2. Description of the Related Art Conventionally, a plurality of ball passages through which balls such as winning balls and premium balls flow down, for example, a rotating body having a concave portion for receiving a pachinko ball formed on the outer periphery thereof so as to correspond to each other. 2. Description of the Related Art There has been known a ball sending device that rotates a rotating body by a motor and sends out a winning prize ball or a prize ball. Such a ball sending device has a structure in which a rotating body facing each ball passage is integrally provided on a motor shaft of one motor.

[0003]

For this reason, there has been a problem that the balls flowing down a plurality of ball passages cannot be sent out while controlling the sending speeds of the balls independently. Further, in order to solve such a problem, it is conceivable to prepare two sets of a rotating body and a motor, which are paired, and provide them at a position away from the ball passage or at the front side and the back side of the ball passage. However, such a configuration has a disadvantage that the installation area of the ball sending device becomes large, and the entire device becomes large. The present invention has been made in view of the above problems,
It is an object of the present invention to provide a ball sending device which can independently control the sending speed of the balls flowing down a plurality of ball passages and requires a small installation area.

[0004]

In order to achieve the above-mentioned object, according to the present invention, a rotating body is made to correspond to a plurality of ball passages through which balls flow, and the rotating body is rotated by a motor so that a pachinko machine is used. In the ball sending device for sending out balls, the motor has a hollow motor shaft of a first motor provided on an output shaft side of a second motor, and the hollow motor shaft has a motor shaft of the second motor. And the rotating bodies corresponding to the plurality of ball passages are respectively independently fixed to the motor shaft of the first motor and the motor shaft of the second motor. It is. When the present invention is applied to a ball game machine using a pachinko ball, a prize ball sending device for paying out a predetermined number of prize balls based on a prize, and a prize ball sending device for processing the winning prize balls one by one. It can be embodied as a device.

[0005]

The pachinko balls flowing down the plurality of ball passages are sent to the downstream side by the rotation of the rotating bodies corresponding to the respective passages. However, since each rotating body is fixed to the motor shaft of a different motor, by setting the rotation speed of the motor arbitrarily, the sending speed of the balls flowing down a plurality of ball passages can be independently controlled. Can be controlled. In addition, since different motors are provided to overlap in the motor axis direction, the installation area can be small.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. An embodiment in which the ball sending device according to the present invention is applied as a prize ball sending device for paying out a predetermined number of prize balls based on winnings is shown in FIGS. 1 to 4, in order to process winning prize balls one by one. 5 and 6 show an embodiment in which the present invention is applied as a winning ball sending device. First, a case where the present invention is applied to a prize ball sending device will be described with reference to FIGS.

First, with reference to FIG. 3, the structure of the mechanism plate 1 on which the premium ball sending device 30 according to the embodiment is installed will be described. FIG. 3 is a rear view showing the structure from one side portion to the lower central portion of the mechanism plate 1, and a predetermined processing is performed based on a winning ball processing mechanism for processing a winning ball and a winning signal processed by the winning ball processing mechanism. The portion of the prize ball sending device 30 that pays out a number of prize balls is shown.

In FIG. 3, winning ball collecting gutters 2a and 2b for collecting generated winning balls are provided in an inclined manner below the mechanism plate 1. Although only one prize-ball collecting gutter 2a, 2b is shown in the figure, it is formed so as to overlap in the front-rear direction. The number of prize balls paid out by the prize balls collected in the prize ball collecting gutter 2a formed on the back side is a relatively large number of prize balls (for example, 13), and the prize balls formed on the front side. The number of prize balls paid out by the winning balls collected in the collecting gutter 2b is a relatively small number of prize balls (for example, seven). In addition, components with "a" attached to each part number described below constitute a mechanism related to thirteen parts in principle, and components with "b" attached to each part number are defined in principle. And a mechanism related to seven of them.

At the ends of the above-mentioned prize-ball collecting troughs 2a and 2b, proximity-type prize-ball detectors 3a and 3b are provided, and prize-ball processing solenoids 4a and 4b are provided below the prize-ball detectors 3a and 3b. (This solenoid has an electromagnet-like function).
In the vicinity of the suction plates 5a, 5b, there are disposed flow-down regulating members 6a, 6b that rotate in accordance with the movement of the suction plates 5a, 5b. When the winning ball processing solenoids 4a and 4b are turned ON, the upper ends of the flow-down regulating members 6a and 6b enter a position slightly above the winning ball detectors 3a and 3b. Further, below the winning ball detectors 3a, 3b, winning ball discharging passages 7a, 7b are connected, and the ends of the winning ball discharging passages 7a, 7b are merged, and a winning signal output detector 8 is connected to the merging portion. Is provided. The above-mentioned winning ball detectors 3a and 3b, the winning ball processing solenoids 4a and 4b,

The operation of the winning ball processing mechanism will be described. Winning balls generated in a game area (not shown) are collected in the winning ball collecting gutters 2a and 2b and flow down in one line. Then, when reaching the winning ball detectors 3a, 3b, they are stopped by contacting the upper ends of the suction plates 5a, 5b. In the stopped state, the first winning ball is located in the ball passing hole of the winning ball detectors 3a and 3b, and thus the winning ball detectors 3a and 3b.
After that, the state in which the winning detection signals Pa and Pb are derived continues. When the winning detection signals Pa and Pb are derived, the stepping motors 42a and 42b of the prize ball sending device 30 described below are driven until the set number of prize balls are discharged.

When the transmission of the predetermined number of prize balls is completed by the prize ball transmitting device 30, the transmission end signals Qa and Qb are derived, and based on the transmission end signals Qa and Qb, the winning ball processing solenoids 4a and 4b are set for a predetermined time. (For example, 0.5 seconds to
1.0 second). Then, the suction plates 5a and 5b are sucked, and the top winning ball stopped at the upper ends of the suction plates 5a and 5b is opened and discharged to the winning ball discharge passages 7a and 7b. At this time, the upper ends of the flow-down regulating members 6a and 6b are earlier than the top winning ball is released.
Since they enter the ends of the a and 2b, the next winning ball is blocked by the upper ends of the flow-down regulating members 6a and 6b and does not flow downward. Then, when the predetermined time has elapsed, the winning ball processing solenoids 4a and 4b are turned off, so that the suction plates 5a and 5b return to the original state.
The next winning ball blocked at the upper ends of the a and 6b abuts on the upper ends of the suction plates 5a and 5b so as to stop in the ball passage holes of the winning ball detectors 3a and 3b. Hereinafter, a predetermined number of prize balls are paid out by repeating the above operations for the next winning prize ball.

The winning balls discharged to the winning ball discharging passages 7a and 7b pass through a winning signal output detector 8 and merge into a ball removing passage 12, which will be described later, and finally to the outside of the pachinko gaming machine. It is ejected, but the winning signal output detector 8
When N, a display lamp (not shown; different from the prize ball payout notification lamp) provided on the game board is turned on.
A prize ball payout notification lamp 24b (indicated by reference numeral in FIG. 4) for notifying that the prize ball has been paid out has a basic circuit 60 described later based on the outputs of the prize ball detectors 3a and 3b.
It is executed by the control of. Further, the winning signal output detector 8 may be used as a detector for giving safe ball data to the management computer. In this case, it is necessary to provide two winning signal output detectors corresponding to each of the winning ball discharging passages 7a and 7b.

At appropriate positions on the curve gutter 9, ball deficiency detectors 10a and 10b are provided as ball deficiency detecting means. When the ball deficiency detectors 10a and 10b do not detect pachinko balls, the drive of the prize ball dispensing device 30 is stopped even if the winning detection signals Pa and Pb are present. However, even if the ball deficiency detectors 10a and 10b are activated while the prize balls are being sent out, the sending operation is continued, and the prize balls corresponding to the prize detection signals Pa and Pb based on the next prize balls are sent out. Operation is stopped. Therefore, from such a viewpoint, the installation position of the ball deficiency detectors 10a and 10b is determined by the number of prize balls discharged from one of the prize detection signals Pa and Pb counted from the ball placement units 35a and 35b described later. It is desirable to be installed above the storage position. When the ball deficiency detectors 10a and 10b are activated, a ball-out lamp 24 provided on the front of the game board.

Are formed, and at the ends of the curved passages 32a and 32b, delivery passages 33a and 33b and ball ejection passages 34a and 34b formed in substantially circular shapes are connected. Therefore, the delivery passages 33a and 33b and the ball ejection passages 34a and 34b are in a state of communicating with each other at the end of the supply passages 32a and 32b. As shown in FIG. 1, the inner passage walls forming the delivery passages 33a and 33b and the ball ejection passages 34a and 34b penetrate recesses 38a and 38b formed continuously on the outer peripheral portions of the sprockets 37a and 37b. Therefore, a notch groove is formed.

The supply passages 32a, 32b guide the supply passages 32a, 32b to positions corresponding to the end portions of the supply passages 32a, 32b and to the connecting portions of the inner passage walls between the delivery passages 33a, 33b and the ball ejection passages 34a, 34b. The ball placing portions 35a and 35b on which the designated top prize ball is placed are formed.
