2. Description of the Related Art A pair of left and right opening / closing bodies are provided on the front surface side of a mounting board, and each base of the opening / closing bodies is pivotally supported by an axis orthogonal to the mounting board, and the opening / closing body is tilted about the axis in both left and right directions. Therefore, an openable-closure type winning device that spreads to a prize winning state is widely known.

In addition, as a means for detecting a game ball, for example,
In the 55-67776 publication, a game car receives a ball at a position facing the exit of a taxiway that flows down, and a rearranging car that is rotated by a motor to send safe balls one by one, and a rearing car at the rear of the rearranging car. There is described a signal generating device in a pachinko machine including a safe ball on a rearranging vehicle and a switch that is opened and closed by making contact with the safe ball.

Conventionally, the detection of safe balls in this type of winning device is
A guiding path for guiding a game ball that wins the winning device downward from the winning device is provided in communication with a winning opening of the winning device, and further communicates with the guiding path to flow down the guiding path. Since the detecting means for detecting the sphere is arranged, it takes time for the gaming sphere to flow down the taxiway from the winning of the gaming sphere to the winning device to the detection of the winning by the detecting means, and a considerable amount. A time lag is required, and the operating time of the accessory or the like linked to the winning of the prize must be taken into consideration.

Therefore, in the conventional open / close type winning device of the pachinko machine, it is necessary to provide a ball passage at the bottom of the winning device and to arrange a prize detecting device for detecting a prize on the ball passage. It was very limited.

In addition, the game ball detection means is provided on the back side of the safe ball receiver, and the wiring board on which the reed switch is fixed is provided on the back side of the safe ball receiver so as to project from the game ball guide box. A magnet is provided on the other end of the lever operating body that controls the opening and closing of the opening and closing body at one end, and one end of the lever operating body is attached to the winning side of the game ball on the shaft that penetrates the side surface of the wiring board and the guide box. It is placed at a position facing to, pivotally supported, and provided with a magnetically transparent opening on the side where the wiring board of the game ball guide box is attached, when the game ball wins the safe ball receiver, The lever actuating body swings due to the fall of the game ball, and the magnetic change caused by the swinging reversal of the magnet at the other end of the lever actuating body is detected by the reed switch from the side of the game ball guide box through the opening. Reed switch mounting structure for safe ball socket of pachinko machine "It is disclosed as Japanese Unexamined Utility Model Publication No. 59-38982.

However, this is a detection method using a reed switch, and therefore, when a fraudulent act of bringing a magnet closer to the game board side is performed, the reed switch malfunctions, which is not suitable for actual use.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention It is an object of the present invention to provide an opening and closing type winning device for a pachinko machine which can prevent the influence of magnetism, can respond to the winning of the pachinko machine quickly, and can be freely arranged on the game board. .

MEANS FOR SOLVING THE PROBLEMS The opening and closing type winning device of a pachinko machine of the present invention is a game machine in which a splashing wheel is provided on the back side of the main body of the opening and closing type winning device at a constant angle with radially projecting springs. The spring is supported so as to rotate freely with the spring facing the path, a micro switch is arranged at the rear of the spring, the switch lever of the switch is formed of an elastic body, and the tip end side is outward. The curved portion of the switch lever is capable of coming into contact with each spring surface of the spring and the shaft outer surface at the same time.

Action When a pachinko ball falls into the open / close-type winning device, it hits one of the springs that protrudes at a constant angle in the radial direction of the splash car, and the splash car is freely rotated by the weight of the pachinko ball. With the rotation of the vehicle, the curved portion near the tip of the switch lever of the micro switch, which is elastically in contact with each of the splash surfaces with respect to the rotation of the flywheel, is located behind the curved portion in the rotation direction. The rotation of the spring pushes it up to actuate the microswitch, and when the spring further moves and passes through the curved portion near the tip of the switch lever, the switch lever elastically returns and the pushed switch lever is pushed up. The curved portion of the spring elastically contacts the spring surface and the shaft outer surface of the spring wheel, and the rotation stop position of the spring wheel is positioned.
The splash wheel stops spinning.

In the initial state in which the pair of opening / closing bodies are closed, the opening prevention protrusions of the left and right opening / closing bodies are abutted from the outside by the both side plates of the splash wheel. It will never be opened.

When a pachinko ball wins between the left and right opening and closing bodies, the falling pachinko ball rotates the splash wheel by pushing down the splash with its own weight, and when the splash wheel passes the interference position with the curved part of the switch lever, The switch lever elastically returns, and the curved portion makes elastic contact with the rear side of the spring and the shaft outer surface of the spring again, so that the rotation stop position of the spring is positioned and the rotation of the spring is stopped. . Thus, the flywheel is rotated 1/3.

When the splash wheel rotates 1/3, the release prevention protrusions protruding from the back side of the left and right opening and closing bodies lose their support by both sides of the splash wheel.
The left and right opening / closing bodies rotate by their own weights about the rotation axis and are opened.

If the pachinko ball wins again with the opening / closing body open, when the pachinko ball passes below the rotation axis along the opening / closing body, the opening / closing body will be closed temporarily, but the pachinko ball will resplash. Even if the car is rotated 1/3 turn, the opening prevention protrusion still loses the support by both sides of the splash car, so the opening / closing body is opened again by its own weight.

Furthermore, if the pachinko ball wins again between the opening and closing bodies, when the pachinko ball passes below the pivot axis of the opening and closing body,
Before the opening and closing body starts the opening movement due to its own weight, the pachinko ball rotates the splashing wheel a further 1/3 turn to return the splashing wheel to the original position, so the opening prevention protrusion of the opening and closing body is splashed again. With the support of both side plates of the car, it keeps closed and returns to the initial state.

Embodiment Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIG. 1, FIG. 2 and FIG.

In FIG. 1, reference numeral 1 denotes an opening / closing type winning device, and an opening / closing body 3 which is opened / closed in accordance with a winning of a pachinko ball is rotatably supported by a rotating shaft 4 in the winning device body 2, and the opening / closing body 3 is provided. An opening prevention protrusion 5 is integrally molded on the back side of the.

On the back side of the winning device body 2, a splash wheel 6 provided with three splashes 9a, 9b, 9c projecting every 120 ° in the radial direction, with the splash 9 facing the course of the game ball. It is pivotally supported to rotate freely. The spring wheel 6 is provided with side plates 6a on both sides of the two springs 9b and 9c which intersect each other in the axial direction.

As shown in FIG. 1, the opening / closing bodies 3 arranged on the left and right sides of the winning device body 2 are attached to the opening / closing bodies 3 by the side plates 6a of the splash wheel 6 on which the respective opening preventing projections 5 are rotatably supported. It is supported in the direction of rotation.

A micro switch 8 having a switch lever 7 and a pressing piece 8a is arranged behind the flywheel 6. The micro switch 8 is formed by inserting the two hanging walls 8b between the two side plates 2a of the winning device body 2 and inserting the detachable pins 10 and 10 between the side plates 2a and the hanging wall 8b. It is detachably attached to the apparatus body 2.

The switch lever 7 is formed of an elastic body, the base end of which is attached to one end of the microswitch 8 provided with the pressing piece 8a, and the other end of which is bent toward the outside in an arc shape. The curved portion 11 is provided, and the curved portion 11 is in elastic contact with the spring surfaces of the springs 9a, 9b, 9c and the shaft outer surface 6b at the same time when the spring wheel 6 rotates.

Therefore, at the stop position of the flywheel 6, as shown in FIG. 3 (A), the spring surface of the spring 9a and the shaft outer surface 6b of the spring 9a contact the curved portion 11 of the switch lever 7. And be positioned.

When the splash wheel 6 rotates, the bending portion 11 moves up and down every 1/3 rotation of each spring to cause the micro switch 8 to move.
Turn on / off.

Next, the operation of this embodiment will be described. First, in the initial state in which the left and right opening / closing bodies 3 are closed as shown in FIG. Since it is supported by both side plates 6a of the car 6, the left and right opening / closing bodies 3 are not opened accidentally by an external impact.

From the state shown in FIG. 3 (A), when a pachinko ball wins between the left and right opening / closing bodies 3, the falling pachinko ball splashes 9c.
The splash wheel 6 is rotated by pushing down by means of its own weight, and the rotating splash wheel 6 moves with the rotational movement of the spring 9a.
The curved portion 11 of the switch lever 7 is pushed up, and the switch lever 7 operates the micro switch 8 by pushing the pushing piece 8a at the base end thereof.

Further, when the spring 9a rotates and passes through the position where the switch lever 7 interferes with the curved portion 11, the switch lever 7
Elastically returns, and the curved portion 11 again elastically contacts the rear side of the spring 9a and the shaft outer surface 6b of the spring wheel 6, whereby the rotation stop position of the spring wheel 6 is positioned and the rotation of the spring wheel 6 is prevented. Be stopped. Thus, the splash wheel 6 is rotated 1/3 by the falling pachinko ball.

Since the winning ball is detected when the winning ball passes through the splash wheel 6, the delay time for detecting the winning ball is extremely short.

On the other hand, when the splash wheel 6 rotates 1/3, the release prevention projections 5 protruding from the rear surfaces of the left and right opening / closing bodies 3 lose the bearing by the both sides 6a of the splash wheel 6 as shown in FIG. Opening and closing body 3
Is rotated about its own axis by its own weight and is released.

If the pachinko ball wins again with the openable body 3 open,
When the pachinko ball passes along the opening / closing body 3 below the rotation axis 4, the opening / closing body 3 is temporarily closed, but even if the pachinko ball makes the splash wheel 6 rotate 1/3 again, Fig. 3 (C)
As described above, since the opening prevention protrusion 5 still loses the support by the both side surfaces of the splash wheel 6, the opening / closing body 3 is opened again by its own weight.

However, when the pachinko ball wins again between the opening / closing bodies 3, when the pachinko balls pass below the rotation axis 4 of the opening / closing body 3, the opening / closing body 3 temporarily starts the opening motion due to its own weight. Since the pachinko ball makes the splash wheel 6 rotate 1/3 more to return the splash wheel 6 to the original position, the opening preventing projection 5 of the opening / closing body 3 is again supported by the side plates 6a of the splash wheel 6. Keeps the closed state and returns to the initial state.

In this embodiment, the open / close type winning device with two continuous openings is described, but as shown in FIGS. 4 and 5, the number of the splashes 9 is set to 4 every 90 ° and the splashes 9 By using the flywheel 6 with every other side plate 6a in between,
Opening or double side plates on only one between the flywheels 6 provided with four splashes 9 every 90 ° as shown in FIGS. 6 and 7.
By using a flywheel 6 having 6a and no side plates 6a between the other three splashes 9, it is possible to change to an open-and-close type winning device having three continuous openings.

The effect of the invention The opening and closing type winning device of the pachinko machine of the present invention is, on the back side of the opening and closing type winning device main body, a splashing wheel provided with a radially projecting spring at a constant angle is provided in the path of the game ball. Since the micro switch is rotatably supported with the feet facing, and the micro switch is placed behind the splash wheel, there is no magnetic influence unlike reed switches, and the switch switch lever is made of an elastic body and located near its tip. Is curved in an arc shape toward the outside and the curved portion of the switch lever is elastically brought into contact with each spring surface of the spring when the spring is rotated, allowing the spring to rotate freely due to the weight of the pachinko ball. However, the curved portion near the tip of the switch lever of the microswitch, which elastically contacts the surface of each spring with respect to the rotation of the flywheel, rotates the spring located on the rear side of the curved portion in the rotation direction. Push by moving When the micro switch is lifted to operate the micro switch, and when the spring rotates and passes the curved portion near the tip of the switch lever, the pushed switch lever elastically returns, and the curved portion of the switch lever is The spring wheel is positioned at the rotation stop position by elastically contacting the shaft outer surface of the spring wheel. Therefore, the drive mechanism for rotationally driving the spring wheel and the positioning means for stopping the rotation of the spring wheel. There is no need to provide a separate device, the device can be downsized, and its arrangement is free anywhere on the game board, and in particular, it is possible to place it at the bottom of the game board, which was extremely difficult in the past.
