Abstract

PURPOSE:To enable a game to be played without touching the control portion of a game machine comprising a digital circuit for controlling generator mechanisms by providing sensors for detecting the arrival of a player at a playing position, and operating a ball shooting mechanism in response to detection signals of the sensors. CONSTITUTION:A game machine is provided with a ball shooting mechanism 2 for shooting game balls onto a game board 1, an openable guide member 4 disposed on the game board 1 to guide the game balls into a scoring slot 3, a throttle device 5 comprising a plurality of display wheels, and a variety of generator mechanisms 6, etc., the generator mechanisms 6 being controlled by a digital circuit comprising a number of IC chips. In this case, sensor means 9 such as a photosensor and an electric wave sensor, etc., for detecting that a player has sat in a position opposite the game board, i.e., for detecting the arrival of the player at a playing position, are installed on the game board 1 and in nearby positions. A predetermined time after detection signals of the sensor means, an output signal is generated from a timer circuit, and the ball shooting mechanism 2 is operated by the output signal to automatically shoot the game balls onto the game board 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unauthorized operation preventing apparatus used in various digital game machines such as pachinko machines and throttle machines.

[0002]

2. Description of the Related Art As this type of game machine, for example, as shown in FIG. 3, a ball firing mechanism 2 for firing a game ball on a board 1 and an openable / closable guide member 4 for guiding the game ball to a winning opening 3, for example. Throttle device 5 and nail 1a, which are composed of a plurality of display wheels
It is known that various accessory mechanisms 6 including the above and the like, and a digital electronic circuit (not shown) for controlling the prize mechanism 6 for prize winning are controlled.

[0006] Conventionally, as an illegal prize ball action in a game machine such as a pachinko machine, a ball is guided to a winning opening 3 by a magnet,
Alternatively, it is generally known that a sensor for detecting a winning ball in the winning opening 3 is caused to malfunction by an electromagnetic wave so that the winning state is achieved.

As a method for preventing these fraudulent prize balls, a magnetic detector or a receiving device corresponding to the frequency of the electromagnetic wave is installed, and an alarm sound or a warning light is emitted when the magnetism or the electromagnetic wave is oscillated near the game machine. An alarm is issued to automatically suspend the game machine, promptly informing the player of the illegal prize ball act.

[0005]

However, in this type of digital amusement machine, when the winning ball is managed, which has a serious influence on the management of the amusement hall, the management data for starting the operation of the ball launching mechanism 2 is used. The number of operations of the rotatable operation handle 7 and the number of operations of the stop button 8 that can arbitrarily stop the operation of the ball firing mechanism 2 by the player's will are grasped, and based on this data, the accessory such as the throttle In some cases, a method of digitally controlling the mechanism to manage the mechanism is adopted. In such a case, if the player can arbitrarily change the number of times of operating the operating handle and the stop button, the player can freely play the role. It can be said that there is an inconvenience that there is a possibility that the prize mechanism may be created by operating the object mechanism.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve these inconveniences, and its gist is to provide a ball launching mechanism for launching a game ball onto a board surface, and various types of balls arranged on the board surface. In a game machine composed of a role mechanism and a digital circuit for controlling the role mechanism, a sensor means for detecting arrival of a player at a play position, and the ball firing mechanism is operated by a detection signal from the sensor means. An tampering prevention device for a game machine, which is characterized by comprising an operating means.

[0007]

The sensor means detects that the player has reached the play position and outputs a detection signal, and the detection means outputs the detection signal, and the actuating means activates the ball launching mechanism, which causes the ball launching mechanism to play on the board. Will fire a ball,
Further, when the player moves away from the play position, the operation of the ball shooting mechanism is stopped.

[0008]

1 and 2 show an embodiment of the present invention. In this case, a ball launching mechanism 2 for launching a play ball onto a board surface 1 and a play ball guided to, for example, a winning opening 3 arranged on the board surface 1. A guide member 4, which can be opened and closed, a throttle device 5 including a plurality of display wheels, various accessory mechanisms 6 including nails 1a, and a digital circuit (not shown) including a large number of IC chips for controlling the accessory mechanisms 6. It is configured.

Reference numeral 9 is a sensor means, which is an optical sensor,
An electric wave sensor or the like is adopted, and it is installed on the board surface 1 and a nearby portion, and when the player sits at a position facing the board surface, the arrival of the game position is detected and a detection signal is output from the detection circuit 10. There is.

Numeral 11 is an actuating means, which sends a signal to the output circuit 13 after a predetermined time has elapsed in the timer circuit 12 after receiving the signal from the detection circuit 10, and actuates the ball launch mechanism 2 by this signal, Shoot a game ball on board 1,
Further, when the player leaves the playing position, the detection signal from the sensor means 9 is interrupted, so that the operation of the ball shooting mechanism is stopped.

Since this embodiment is constructed as described above, the sensor means 9 detects the arrival of the player at the play position and outputs a detection signal. The detection signal from the sensor means 9 causes the actuating means 11 to move the ball. The firing mechanism 2 can be operated, and the operation of the ball firing mechanism 2 can be stopped when the player leaves the playing position. Therefore, the operation handle 7 and the stop button 8 for operating the ball firing mechanism 2 can be operated. It can be a game machine with a lost structure.

Therefore, as in the conventional case, the player arbitrarily changes the number of times the operating handle 7 and the stop button 8 are operated,
It is possible to prevent a player from freely operating the accessory mechanism 6 to create a winning state by his / her own initiative, and the player can play without touching the operation part, and infection of an infectious disease, etc. The effect on public health can also be obtained by preventing this, and further, it is possible to prevent double hitting by one player.
As a result, it is possible to reduce the management staff of the amusement hall and to smoothly operate the amusement hall.

The present invention is not limited to the above embodiment, but can be applied to various game machines such as a digital pachinko machine, a digital throttle machine, a so-called hi-ki pachinko machine, etc. The structure and the like of the mechanism 6 are appropriately designed and changed.

[0014]

As described above, according to the present invention, the operating handle and the stop button can be eliminated, so that the player can arbitrarily change the number of times of operation and the player can freely operate the accessory mechanism. It is possible to prevent the winning state from being created by one's own initiative, and the player can play without touching the operation part, preventing infection of infectious diseases, etc. and obtaining public health effects. Can prevent double hitting by one player, so that it is possible to reduce the number of managers of the game hall and to smoothly operate the game hall.

As described above, the intended purpose can be sufficiently achieved.
