DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a pachinko machine that detects when a game ball passes through a guide gutter or the like provided on the back surface of a game board for guiding a winning ball, for example. The present invention relates to a winning detection device for a gaming machine.

[Conventional technology]

Conventionally, a pachinko game machine is provided with a device for detecting passage of a winning ball, a driving ball, a supply ball, etc., and a non-contact type proximity switch having an oscillation coil as a detection coil is used for the device. Has been done. FIG. 6 is a perspective view of a conventional flat package type proximity switch, and FIG. 7 is a schematic sectional view of a variable winning device provided with a conventional proximity switch. In FIG. 6, 61 is a proximity switch, 62 is a through hole through which a game ball passes, 63 is a detection unit having an oscillation coil embedded around the through hole 62, 63a is the tip of the detection unit 63, 64 is an amplification circuit, etc. Is a package base provided with, and 65 is a lead wire. Further, in FIG. 7, 70 is a game board and 71 is a game board.
A variable winning device provided at the bottom of 70, 72 is a big winning opening, 73
Is the opening / closing door of the big winning opening 72, 74 is a guide gutter that guides the winning ball,
75 is a housing portion for housing the proximity switch 61, 76 is a guide piece that fills a step with the tip portion 63a of the proximity switch 61, 77 is a front glass plate of the pachinko gaming machine, and 78 is a game for collecting prize balls in one place. A winning ball set protection plate provided on the back surface of the board 70, and 79 is a mounting substrate. Incidentally, 90 is a game ball.

Now, when the game ball provided on the game board 70 wins, the opening / closing door 73 of the special winning opening 72 is opened as shown in FIG. 7,
The winning ball 90 is guided by the guide gutter 74. Then, when the winning ball 90 passes through the through hole 62 of the proximity switch 61 arranged in the accommodation portion 75 of the guide gutter 74, the proximity switch 61 emits a detection signal. Based on this detection signal, operation according to winning value,
For example, a predetermined prize ball is discharged.

[Problems to be Solved by the Invention]

By the way, the side surface 62a, the side surface 62b, and the side surface 62c of the through hole 62 of the proximity switch 61 arranged in the guide gutter 74 can be attached so as to be flush with the inner surface of the guide gutter 74.
However, in the conventional pachinko gaming machine, the side surface 62d of the proximity switch 61 is not flush with the back surface of the mounting substrate 79 of the variable winning device 71 because the detection coil is embedded around the through hole 62. As shown in FIG. 7, a protrusion is formed in the guide trough 74 due to the thickness of the tip portion 63a. Therefore, in the conventional pachinko gaming machine, the winning ball 90 that has fallen is inclined to the upper portion of the housing portion 75 as shown in FIG. 7 so as not to collide with the tip portion 63a (projection portion) of the through hole 62. There is a drawback in that the structure of the passage becomes complicated because it is necessary to provide a guide piece 76 having such a surface or to embed the tip portion 63a of the proximity switch 61 in the back surface of the mounting substrate 79.

Further, as shown in FIG. 7, when the conventional proximity switch 61 is arranged vertically on the back surface of the variable winning device 71, the gap between the mounting substrate 79 of the variable winning device 71 and the winning ball set protective plate 78 is narrow. Therefore, the lead wire 65 of the proximity switch 61 was pressed and bent by the winning ball gathering protection plate 78, and an unreasonable pressure was applied to the lead wire 65. Therefore, in the conventional pachinko game machine, if it is used for a long time, it may malfunction due to disconnection of the lead wire 65, etc., and there is a problem in terms of durability and reliability.

Some of the conventional game ball passage detecting devices have a shape in which the tip of the detecting portion is cut out as shown in FIG. 8 (Shokai Sho 60-23076). FIG. 8 (a) is a plan view thereof, and FIG.
FIG. 2B is a schematic cross-sectional view as seen from the side surface. The gaming ball passage detection device 80 detects the passage of the winning ball 90 by the displacement of the actuator 82. By the way, the cutout portion 81 provided in the detection unit 83 regulates the passage of the game ball so that the center of the game ball passes through the center of the detection unit 83 by the so-called three-point support concept. Therefore, in the gaming ball passage detection device 80, when the tip of the detection unit 83 is formed in an open state,
It becomes impossible to regulate the passage of the game ball and the operation becomes unstable. As described above, since the gaming ball passage detection device 80 shown in FIG. 8 cannot form the tip of the detection portion 83 in an open state, the pachinko gaming machine using such a game ball passage detection device 80 also has the same structure as described above. There were similar drawbacks.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a winning detection device for a pachinko gaming machine, which can simplify and downsize the structure of the passage of the game ball.

[Means for Solving the Problems]

The present invention for achieving the above-mentioned object is a ball passing portion in which a through hole having an open end through which a game ball passes is formed, and a central axis of a winding is substantially orthogonal to a passing direction of the game ball. And an oscillation coil provided facing the through hole on the side opposite to the open one end, and the change in the inductance of the oscillation coil generated when the game ball passes through the ball passing portion is electrically changed. And a circuit board on which the oscillation coil is attached and the circuit of the oscillation section is formed so that the central axis and the substrate surface are parallel to each other. It is characterized in that it comprises a detection part, the ball passage part and the detection part are formed in a flat plate shape, and the thickness thereof is smaller than the diameter of the game ball.

[Action]

According to the present invention, the oscillation coil is arranged at a part of the side portion of the ball passing portion so that the central axis of the winding thereof is substantially orthogonal to the passage of the game ball, and the oscillation coil penetrates through the ball passing portion. Since one end of the hole is open, even if the device of the present invention is arranged in the passage of the game ball, the ball passage portion and the oscillation coil do not become an obstacle when passing the game ball, and thus the passage The structure is simple and small.
