DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine in which a pachinko ball of a ball tank flows down, and a proximity switch is provided at a predetermined position to accurately detect the ball breaking.

[0002]

2. Description of the Related Art A conventional pachinko machine has already been provided with a ball-break detecting device in the middle of a lead-out gutter for guiding pachinko balls in a ball tank to a pachinko ball dispensing device, particularly near a ball tank. . The ball cut detector is provided with an opening on the bottom surface of the lead-out gutter and has one end pivotally supported by the opening, and faces an operating plate that is urged to always rotate upward about the pivotal support portion. A limit switch is provided below the operation plate. When there is a pachinko ball in the lead-out gutter, the operation plate is pushed downward by the weight of the pachinko ball and the limit switch is turned on. When the pachinko ball runs out, the operation plate rotates upward and the limit switch is turned on. The off state is notified when the ball has run out.

[0003]

However, in this pachinko machine, even if the pachinko balls do not ride on the upper surface of the operation plate due to dirt or dust on the operation plate and the like, the operation cannot be performed normally and the ball cannot be operated normally. There is a possibility that the ball may remain rotated downward and the ball cut may not be accurately detected.

[0004] In addition, the ball tank is usually provided with a discharge port communicating with the outlet gutter, but almost immediately below the discharge port of the ball tank, many pachinko balls are discharged at once through the discharge port. In this area, the pachinko balls exert a force on each other, so that a so-called bulging state is maintained, and the ball is clogged easily. When this ball clogging phenomenon occurs, the limit switch remains on, and not only can the ball out be accurately detected, but also the number of pachinko balls dispensed at one time from the pachinko ball dispensing device may not reach a predetermined number, As a result, there was a problem between the pachinko hall and the customer.

In view of the above, the present invention has been made in view of the above-mentioned problem, and it is possible to detect a pachinko ball after a proximity switch is a lead-out gutter, which is surrounded by a wall of the lead-out gutter and rectified in a line. And a pachinko machine provided at a position where a predetermined number of pachinko balls to be dispensed at one time from a pachinko ball dispensing device are secured, so that a broken ball in the lead-out gutter can be accurately detected. Is what you do.

[0006]

In order to achieve the above object, a pachinko machine according to the present invention is directed to a pachinko machine in which a pachinko ball dispensing device is provided at an end of a lead-out gutter through which a pachinko ball of a ball tank flows down. It is a gutter, and it is possible to detect pachinko balls after being rectified in a line surrounded by a wall of the outlet gutter and rectified, and a predetermined number of pachinko balls dispensed at a time from the pachinko ball dispensing device are secured. A proximity switch is provided at the position, and the proximity switch detects a ball break in the outlet gutter. The proximity switch is provided, for example, at a corner on the downstream side of the outlet gutter. This is because the corner portion is formed in a tubular shape whose periphery is surrounded by the wall of the lead-out gutter so that the pachinko balls can be arranged in a line and pass through, so that ball clogging does not occur at all.

[0007]

As described above, the proximity switch is provided at a position where a pachinko ball which is a lead-out gutter, which is surrounded by the wall of the lead-out gutter, and which is rectified and arranged in a line can be detected.
If the ball is clogged on the upstream side of the proximity switch, the pachinko ball downstream from the proximity switch is rectified and flows down, so that when the ball runs out, the proximity switch is turned off and accurate detection is possible. At this time, since the detection switch is provided at a position where a predetermined number of pachinko balls to be dispensed at one time from the pachinko ball dispensing device are secured, the pachinko balls will not be dispensed in a shortage state that does not reach the predetermined number. .

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a back view of a pachinko machine to which the present invention is applied. In the drawing, reference numeral 1 denotes a game board, 2 denotes a mechanism plate which is openably and closably mounted on the back of the game board 1, and 3 is fixed to an upper portion of the back. The ball tank 4 transfers the pachinko balls in the ball tank 3 to the ball passages 4a,
A pachinko ball dispensing device 6 which is electrically operated is connected to an end of a corner portion 5 which is bent in a U-shape on the downstream side, with lead-out gutters led out in two rows of 4b. Further, a discharge passage 7 is formed below the pachinko ball payout device 6 for guiding the paid-out pachinko balls to a hit ball supply tray (not shown).

The pachinko ball dispensing device 6 is shown in FIGS.
As shown in the figure, the main body base 8, the drive motor 9, the lead screw 10, and the cover 11 are roughly constituted. On the front surface of the main body base 8, the ball passages 4a, 4b of the outlet gutter 4 are provided.
The two supply passages 12a and 12b communicating with the pachinko ball are formed at right and left intervals, and discharge passages 13a and 13b for pachinko balls are formed downstream of the supply passages 12a and 12b, respectively. The drive motor 9 includes a motor mounting frame 14.
Is attached to the center of the front of the main body base 8 via
The lead screw 10 is disposed below the driving motor 9 and between the supply passages 12a and 12b.

As shown in FIG. 5, the lead screw 10 is provided on the outer peripheral surface of the cylindrical body 15 with the supply passages 12a and 12a.
A ridge 16 for receiving the state-of-the-art prize ball is spirally provided facing the surface 12b, and a rotary shaft 17 protruding in the vertical center of the cylindrical body 15 is mounted on the bearing pieces 18, 1 of the main body base 8.
8 so as to be horizontally rotatable. A driven gear 21 meshing with a driving gear 20 fixed to a motor shaft 19 is fixed to the tip of a rotating shaft 17 protruding above the cylindrical body 15, whereby the rotation of the motor shaft 19 is transmitted to the lead screw 10. It is supposed to. The ridge 16 of the lead screw 10 has a spiral shape such that the leading end pachinko ball of the supply passages 12a and 12b loses support and falls into the discharge passages 13a and 13b by one rotation of the lead screw 10. The shape is chosen. Also, premium ball detectors 22a, 22b are provided in the discharge passages 13a, 13b, and the pachinko balls to be paid out to the discharge passages 13a, 13b by rotation of the lead screw 10 are detected one by one. .

In the present invention, as shown in FIGS. 3 and 4, on the upstream side of the corner portion 5, on the back surface of the bottom wall 23, the proximity switch 2 having the detecting portion 24a corresponding to one of the spherical passages 4a.
4 and a proximity switch 24 'corresponding to the detection unit 24b in the other ball passage 4b. That is,
The corner portion 5 is formed in a cylindrical shape in which the periphery of each ball passage 4a, 4b is surrounded by the wall of the lead-out gutter 4 and the pachinko balls can pass in a line, so that the pachinko balls flowing down therethrough are balls. The proximity switches 24, 24 ', more specifically, both the detection units 24a, 24b, are mounted at positions where the rectified pachinko balls can be detected without causing biting of the ball and causing biting of the ball. Become.

Each of the detecting portions 24a and 24b is provided with a number of payouts at a time by the pachinko ball payout device 6 from the detecting portions 24a and 24b to the end of the ball passages 4a and 4b from the downstream side to the end. Positions where the same number of pachinko balls are lined up. Thus, the two proximity switches 24,
The reason why 24 'is made to correspond to each of the ball passages 4a and 4b is that it is not clear which ball passage 4a or 4b causes a ball break. For example, a ball break occurs in one ball passage 4a and the other ball passes. Even when the pachinko ball is not generated in the passage 4b, the pachinko ball discharging device 6 stops the paying out of the pachinko ball by detecting it.

The present invention is constructed as described above, and when a pachinko ball is present in each of the ball passages 4a, 4b of the outlet gutter 4,
Each of the proximity switches 24 and 24 ′ operates to detect the presence of a pachinko ball, and the lead motor 10 is rotated by the drive motor 9 of the pachinko ball dispensing device 6 to pay out the pachinko ball. On the other hand, a ball clogging occurs on the upstream side of each of the proximity switches 24, 24 ', and the ball passages 4a,
When one or both of 4b and 4b are out of the ball,
When the proximity switches 24 and 24 'operate to detect the absence of a pachinko ball, the drive motor 9 of the pachinko ball discharging device 6 is turned off, the rotation of the lead screw 10 is stopped, and the discharging of the pachinko ball is stopped.

During this time, even if the pachinko balls remain in the ball passages 4a and 4b, the number of the combined balls is the same as the predetermined number of pachinko balls to be paid out at one time by the pachinko ball payout device 6, so that the paying out is performed. Even if the pachinko balls are issued, a predetermined number of pachinko balls are paid out, so that there is no shortage of pachinko balls, and no trouble occurs between the pachinko hall side and the customer. Proximity switches 24, 24 'are provided at positions on the outlet gutter 4 where the balls do not act and pachinko balls can be detected after the flow is rectified, and the proximity switches 24, 24' cut the ball. Since the detection is performed, even if dirt or dust adheres to the pachinko ball, it is possible to accurately detect the out-of-ball without any relation. Although the proximity switch is used in the present invention,
In addition, a sensor that can be detected from outside the corner portion, for example, a photo sensor may be used.

[0015]

As described above, the pachinko machine according to the present invention is a lead-out gutter for flowing down a pachinko ball of a ball tank, which is surrounded by the wall of the lead-out gutter and is straightened in a line. Since the proximity switch is provided at a position where the pachinko ball can be detected, it is possible to accurately detect a ball break in the lead-out gutter, thereby preventing the pachinko ball dispensing apparatus from causing an error. Also, since the proximity switch is provided at a position where a predetermined number of pachinko balls to be dispensed at one time from the pachinko ball dispensing device are secured, even if the ball is out of ball, the number of pachinko balls to be dispensed does not reach the predetermined number and becomes insufficient. This has the effect that troubles between pachinko halls and customers can be avoided.
