JPH0726800B2 - A hit detection mechanism for shooting play equipment - Google Patents

Description

TECHNICAL FIELD The present invention relates to a hit detection mechanism attached to a part of a player's body when performing a shooting game using a ray gun.

[Prior Art] US Pat. No. 346676 as a shooting play equipment using a ray gun.
No. 1 is disclosed. In the shooting play equipment of the US patent, a light gun and a light detector are connected, and the light detector is attached to a helmet and fixed in a predetermined direction.

[Problems to be Solved by the Invention] However, when two or more players play a shooting game using the above-mentioned light ray detector, the light ray detector tilts or rotates the helmet due to the intention or negligence of the player. By doing so, it may be difficult to detect light rays, which may prevent fair game execution.
Also, when the ray detector is activated by the ray emitted from the ray gun, it informs that the bullet has hit by sound or blinking the light, but it is given directly to the surface of the player's body. Since it was not a physical stimulus, it was not realistic as a shooting playground equipment, and there was room for improvement.

[Means for Solving Problems] The present invention has been made to solve the above problems, and the light receiving unit of the light ray detection mechanism has a cylindrical outer shell. Is formed of a transparent material, and a conical protrusion having a peripheral surface formed into a reflecting mirror surface is provided on the lower surface of the top wall in the cylinder, and a photosensor is disposed on the bottom surface. .
