Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a safe ball detector in a pachinko machine, which is used for detecting a safe ball in a pachinko machine.

[Prior Art] Conventionally, a device of this type is publicly known, and therefore, illustration thereof is omitted. Generally, a safe ball is dropped in a vertically arranged square pipe, and a micro switch is provided corresponding to the drop passage.
A coil, a hall element or the like is arranged, and a detector for detecting a falling pachinko ball is output to a computer provided separately.

[Problems to be Solved by the Invention] However, each of the above conventional devices has the following drawbacks. As described above, the microswitch and other various detectors all detect a falling ball, so that the passing speed of the ball is fast and the ON time of the output signal to the computer is short. Also, if the balls pass continuously,
OFF time becomes shorter.

In either case, it is not possible to obtain a sufficient signal width for the computer to accept the signal. In order to output a signal that can be received by a computer, it is usually necessary to extend the output signal to approximately 100 msec or more in both ON and OFF times, but for that, an appropriate number of spheres is temporarily stored and then sequentially output. Must be done.

Therefore, in general, a complicated signal output device including a storage device is provided, and the price is inevitably high.

The present invention has been made to solve such a problem, and its purpose is to manufacture it at a low cost with a very simple structure without the need for a complicated signal output device including the conventional storage device. Moreover, it is an object of the present invention to provide a safe ball detector in a pachinko machine capable of outputting a signal having a sufficient width, detecting balls falling continuously, at a constant interval, and outputting them to a computer.

[Means for Solving the Problems] This invention for achieving the above object will be described. It is pivotally mounted 5 on a frame 4 having a pachinko ball passage 3 between an inlet 1 and an outlet 2. Balancer 6; Pachinko ball receiving portion 7 and closing portion 8 for closing the passage 3
The balancer 6 having a; normally, the receiving portion 7 is urged to be in a first state capable of receiving a pachinko ball, and when the receiving portion 7 receives the pachinko ball, the pachinko ball Of the balancer 6 in the second state by closing the passage 3 on the inlet 1 side by the closing portion 8 due to the weight of the balancer 6; The balancer 6 that drops the ball of the receiving portion 7 to release it and returns to the first state by the biasing; the operating member 10 of the signal device 9 provided on the balancer 6; the frame 4 Also, the signaling device 9 operated by the operating member 10;
Both first and second stoppers that prevent the balancer 6 from rotating
11 and 12; projections 19 provided at positions obliquely below the shaft attachment portion 5 of the frame 4 and in positions that can contact the outer circumference of the pachinko ball held by the balancer 6. It is a safe sphere detector.

[Operation] The pachinko ball is fed from the entrance 1 to the balancer 6 in the first state.
Into the receiving portion 7 of. Then, the balancer 6 is rotated by the weight of the ball against the bias and is blocked by the second stopper 12 to be in the second state. Then, in the process, the actuating member 10 provided on the balancer 6 actuates the signal device 9 provided on the frame 4 to emit a signal. Further, in that case, since the closing portion 8 closes the passage 3, if there is a succeeding ball, the ball is blocked from passing through,
You will have to wait. Next, when the balancer 6 is in the second state, the ball received in the receiving portion 7 falls,
Release. Then, the balancer 6 that has lost the ball rotates in the opposite direction to the above-mentioned rotation by the full bias, and the closing portion 8 moves the passage 3
Is released, the receiving portion 7 is ready to receive a ball, and is prevented from rotating by the first stopper 11 to return to the first state. The above operation is repeated below. The signal generated by the signal device 9 can generate a signal having a sufficient width for reception by a computer.

Further, when the pachinko ball flows into the receiving portion 7 of the balancer 6 and is rotated, when the pachinko ball held by the balancer 6 is obliquely below the shaft attaching portion 5 due to the rotation,
Attempting to get out of the receiving part 7 slightly, the frame 4
It comes in contact with the protrusion 19 provided on the rear side and is returned to the receiving portion 7.
Thus, the rotation speed of the balancer 6 can be prevented from increasing. In addition to this effect, the signal emitted by the signal device 9 or the detector 14 can be made a signal having a sufficient width for reception by the computer.

[Embodiment] In FIGS. 1 and 2, reference numeral 4 denotes a frame having an inlet 1 and an outlet 2 of a pachinko ball 13 and a passage 3 therebetween. A balancer 6 is pivotally mounted on the frame 4 so as to be swingable. The balancer 6 is formed with a notch-shaped receiving portion 7 that receives a pachinko ball and an arc-shaped closing portion 8 that closes the passage 3. Normally, as shown in FIG. 1, the receiving portion 7 is a pachinko ball. 13 is acceptable, that is, the first state. And this is the balancer 6
As an example, the balancer 6 is formed in the first state due to gravity, and the balancer 6 is formed so that the approximate position A shown in FIG.

The urging in the above case is performed by gravity as an example, but this urging may be performed by other springs or the like. In that case, a spring is provided between the frame 4 and the balancer 6 to perform the same urging. To do so. Next, 10 is an actuating member, which is provided on the balancer 6 and is provided with a magnet piece as an example. Further, a reed switch is provided as a signal device 9 on the frame 4, and the reed switch is closed when the magnet piece approaches and the reed switch is opened when it is separated. However, it goes without saying that the signal device 9 and the actuating member 10 for actuating the signal device may be of a suitable known type other than the above.

It is preferable that the magnet piece be formed so as to also serve as a weight of the balancer 6. Reference numerals 11 and 12 denote both first and second stoppers. Next, in the one shown in FIG. 1, the balancer 6 is provided with the actuating member 10, and thereby the signal device 9 provided in the frame 4 is actuated. As shown in the figure, a pachinko ball detector 14 for outputting to a computer may be provided in the passage 3a below the passage 3 through which the pachinko ball passes.

Even if formed in this way, it is possible to output a signal having a signal width longer than that of the conventional one, similar to the transmitting means.

In FIG. 3, 15 is a casing provided with the frame 4, 16 is a bottom plate, 17 is a running path, 18 is a drop gutter of a safe ball, and 13 is a pachinko ball.

Further, in FIG. 1, reference numeral 19 denotes a protrusion, which is provided in order to bring the ball 13 into contact with the protrusion 19 and not to increase the rotation speed of the balancer 6. 20 is a protrusion, which is a sphere
When the ball 13 is dropped, the ball 13 is not brought into contact with the projection 20 to prevent the drop speed from increasing.

Further, reference numeral 21 is a projecting portion for securely holding the pachinko ball 13. 22 indicates a balance part.

[Advantages of the Invention] The present invention is configured as described above, and the signal device 9 provided on the frame 4 is operated by the operation member 10 provided on the rotating balancer 6, and the following ball passes during that time. , The signaling device 9 can emit a signal having a width long enough for the computer to receive. Further, it is possible to provide a safe ball detector in a pachinko machine which has a simple structure and can be manufactured at low cost. Further, the one in which the detector 14 is provided in the passage 3a can also obtain the same operational effect. Further, the one using gravity as the biasing means can perform the biasing which does not change with time.

Further, when the pachinko ball flows into the receiving portion 7 of the balancer 6 and rotates, the pachinko ball held by the balancer 6 slightly moves when the pachinko ball held by the balancer 6 is obliquely below the shaft mounting portion 5 due to the rotation. When attempting to come out of the receiving portion 7, the projection 19 provided on the frame 4 is brought into contact therewith and is returned to the receiving portion 7. Thus, the rotation speed of the balancer 6 can be prevented from increasing. In addition to this effect, the signal emitted by the signal device 9 or the detector 14 can be made a signal having a sufficient width for reception by the computer.
