Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a ball game machine represented by a pachinko game machine, a coin game machine, an arrangement-type pachinko game machine, or the like.
Specifically, it relates to a ball game machine in which a ball is hit in a game area to play a game.

[Prior Art] In this type of ball game machine, for example, a game machine is arranged in the center of a game area, which is generally known in the past, and a ball is struck below the game machine. There was one that was equipped with a winning ball device that can win. And there is a need to maximize the period during which the player can enjoy the falling situation of the hit ball with the expectation that the hit ball hit in the game area may win this winning ball device. there were. For that purpose, it is necessary to provide the winning ball device below the game area as much as possible.

Also, in the conventional ball game machine, the more complicated the electric drive device arranged on the game board, or the larger the number of electric drive devices, the more the ball detection switch is However, when the number of ball detection switches increases, there is a problem that the mounting space for mounting the ball detection switches becomes insufficient. Therefore, for example, JP-A-51-146938
As described in Japanese Patent Publication, when a hit ball that is hit in the game area hits a predetermined winning area, it is possible to use a technique in which the winning ball detecting means for detecting the winning ball is configured by a proximity switch. Conceivable.

[Problems to be Solved by the Invention] This proximity switch is a type of switch that generates a constant magnetic field and detects that the magnetic field changes due to passage of a ball, and the switch has a relatively small (thin) configuration. It has the advantage that it can be done. By using this proximity switch as the hitting ball detection means, there is an advantage in the mounting space of the detection switch, and there is an advantage that many detection switches can be easily provided. Moreover, because there is generally an outlet at the bottom end of the game area,
When the winning ball device is provided at a position as low as possible in the game area, there is a problem in that it is not possible to secure a large mounting space for a ball detection switch that detects a winning ball that has won the winning ball device because of the outlet. If this ball detection switch is composed of the proximity switch, a small mounting space will suffice.

Further, in the above-described winning ball device, it is general that a plurality of winning regions in which hit balls are won are arranged in the lateral direction. Of such a plurality of winning areas, for example, a detection switch for exclusively detecting only winning balls that have won in a specific winning area (for example, a central winning area) is provided.
Furthermore, if a detection switch is provided which is located downstream of the detection switch and collects all the winning balls that have won from the plurality of winning areas in one place and detects the collected balls, the collective ball is detected. The detection of the balls by the detection switch is delayed, a delay in the detection of the winning ball occurs, and there is an inconvenience that a delay in the control occurs due to the detection delay, and the winning ball that has won a prize in the specific winning area is generated. Since the ball detection switch is detected again by the ball detection switch after it is detected by the ball detection switch, the space for mounting the ball detection switch is limited due to the provision of the upper-side ball detection switch and the lower-side ball detection switch. Since it is necessary to secure them in a state of overlapping in the vertical direction, there arises a disadvantage that it is difficult to provide the winning ball device below the game area.

On the other hand, in the proximity switches described above, a magnetic field for detection is generated in the vicinity of the switch body, and when the proximity switches are arranged close to each other, the magnetic fields of the proximity switches interfere with each other and the operation of each proximity switch becomes unstable. There was a drawback that

Further, in the above-mentioned conventional ball game machine, a coil as an electronic element forming a proximity switch is provided at a ball passing position, and a passage detecting circuit for detecting passage of the ball is provided, and the passage detecting circuit is provided. It is necessary to wire-connect the above-mentioned coil and the above-mentioned coil, and when manufacturing the ball game machine, not only the complicated work of making the wire connection between the coil and the passage detection circuit is required, but also by the wire-connection work. There is a drawback that a connection error may occur.

On the other hand, there is a case where the design or shape of the surface of the mounting substrate is changed in order to change the image of the winning ball device, and such a design change can be made easily and at low cost. There is also a required need in terms of manufacturing the winning ball device, such that the manufacturing of the winning ball device is easy.

In short, in the conventional ball game machine provided with the winning ball device, it is difficult to install the winning ball device in the lowermost position of the game area due to the problem of the mounting space of the hitting ball detection means, and the detection delay of the winning ball occurs. In addition, when the hitting ball detecting means is configured to detect the change in the magnetic field caused by the passing of the ball, mutual mutual interference of the hitting ball detecting means occurs, and the mounting work and arrangement / connection of the hitting ball detecting means. There was a drawback that was complicated.

The present invention has been conceived in view of the actual situation, and an object thereof is to solve the problem of the mounting space of the hitting ball detection means, thereby facilitating the installation of the winning ball device at a position as low as possible in the game area and at the same time winning balls. It is possible to prevent the detection delay of, and to avoid the mutual interference of the hitting ball detection means, the installation work of the hitting ball detection means and the wiring connection are simple, there are few connection wiring mistakes, and moreover, in terms of manufacturing the winning ball device described above. It is to provide a ball game machine that can meet the demand needs.

However, in the case of this circuit, L = L1 + L2 + 2M (M is a mutual inductance).

In the circuit of FIG. 10, the coils L1 and L2 correspond to the coil 84 shown in FIG. Therefore, when the pachinko ball passes through the coil 84, the inductances of the coils L1 and L2 change, the resonance condition is not satisfied, and the transistor Q1 turns off.

Expression (1) of the resonance frequency f ₀ of the resonance circuit in the above description
Therefore, it is clear that the resonance frequency f ₀ of the resonance circuit can be changed by changing the capacitance of the capacitor C1 or the inductance of the coil L1 or L2 within an appropriate range. In this embodiment, the capacitance of the coil C1 is changed within an appropriate range, and the resonance frequencies f ₀ of the winning ball detection switches 18, 20, 22 are set to be different from each other. This is one of the features of this embodiment.
