In FIG. 1, 1 is a laser gun equipped with a barrel 1a, a trigger 1b, and an infrared light emitting device 1c, 2 is a screen, 3 is a supporting device thereof, 4 is a projector, 5 is a video camera, and 6 is a filter for blocking external light. , 7 are infrared ray receiving devices provided in a position close to the laser gun and away from the screen 2,
Reference numeral 8 indicates a control circuit (not shown), a laser disk player, a cabinet that also houses a hit detection device, 9 indicates a control device, 10 indicates a light beam for an image display that produces a spot 10a on the screen 2 projected from the projector 4, 11 Is fired from laser gun 1 and screen 2
A laser beam 11 ′ is generated on the spot 11 aa, and a light beam 11 ′ is reflected from the spot 11 a, passes through the filter 6, and is incident on the video camera 5.

It is recommended that the filter 6 preferably transmits only the laser beam emitted by the laser gun 1.

The laser disk player, the control circuit, and the hit detection device (not shown) respectively record a video signal necessary for projecting an image including a target on the screen 2, a game program, and target position information for each frame. is there.

Then, the video signal is converted by the projector 46 into an image including the spot 10a and projected on the screen 2.

The image of the spot 10a is emitted as a single light beam 10 from the projector 4, and the image moves on the screen 2 while changing the brightness and color tone in accordance with the video signal.

Various types of video cameras 5 have been developed according to the use, and a typical one is that an optical system can form an optical image on the photocathode and the optical image can be targeted by electronic means. The above-mentioned electronic image is converted and the electronic image is scanned by an electron beam or the like to obtain a video signal.

On the other hand, since the player can see the image projected on the entire surface of the screen 2, the target spot 10a in the image can be seen.
In order to aim at, the player directs the barrel 1a of the laser gun 1 toward the screen 2, and the oscillation from the infrared light emitting device 1c, as will be described later in detail in FIG. Is received by the infrared light receiving device 7 provided in the laser gun 1 and transmitted to the control circuit of the laser gun 1 through the control device 9 so that the laser gun 1 can emit a laser beam. At this time,
When the player pulls the trigger 1b of the laser gun 1, a laser beam 11 is emitted from the barrel 1a, and when it hits the screen 2, a spot 11a is produced.

Thus, if this spot 11a is within the target range preset according to the movement of the target spot 10a, the laser beam emitted from the laser gun 1 has hit, and if it is distracted, it is removed. It will be.

FIG. 2 is a block diagram showing the details of the safety device of the laser gun beam device equipped with the safety device according to the present invention. In FIG. 2, 12 is an oscillation circuit and 13 is a pulse from the oscillation circuit 12. Modulation circuit, 14 is an infrared light emitting diode that oscillates the pulse modulated by the modulation circuit 13, 15 is an infrared phototransistor, 16 is an amplification circuit, 17 is a code recorder that decodes the pulse code amplified by the amplification circuit 16, 18 receives the signal from the above code recorder 17,
It is a control circuit that enables the laser gun 1 to be fired.

Thus, the infrared light emitting device 1c has an oscillation circuit 12, a modulation circuit 13

When the laser gun is not directed toward the screen, the infrared phototransistor 14 does not receive the light emitted from the infrared light emitting diode 15, so that the above operation is not performed and the laser beam is not emitted.

Further, since the infrared light receiving device is installed at a position away from the screen provided at a position easily noticeable, it is inevitably installed at a position difficult to confirm,
Even when there are many infrared light emitting sources in the vicinity such as in a game center, an infrared beam emitted from a source other than the laser gun is detected, and no malfunction occurs.

This allows the player to trigger the laser gun 1 as described above.
When 1b is pulled, the laser beam is emitted toward the screen only when the muzzle of the laser gun 1 faces the screen, so the laser beam is always emitted only in the proper direction.

〔The invention's effect〕

Since the present invention is configured as described above, according to the present invention, the laser beam is emitted only when the player pulls the trigger by directing the muzzle of the laser gun into the screen. It is possible to provide a laser gun game device equipped with a playable safety device.
