Abstract: A gun game machine wherein the player can hold a model gun in the hand away from an machine casing. This gun game machine comprises a bullet hitting optical detection unit installed in the model gun for detecting a simulated bullet hitting position, a sliding cover provided on an exposed outward portion of the gunbarrel of the model gun and slidable in the longitudinal direction of the gunbarrel section, and a cover driving means for instantaneously moving the sliding cover at high speed. The model gun and the game machine casing may be coupled to each other by means of a flexible cable containing electric conductors. The sliding cover makes a long reciprocating motion similar to the so-called blow-back movement of an actual gun, so that the player can feel a similar reaction or impact corresponding to the firing of the actual gun. This simulated firing operation also serves to attract spectators to the game.

Abstract: A game machine has a plurality of targets which unpredictably come out and disappear from their corresponding holes at the surface of a table on a game stand. A player can only strike targets which are positioned above the surface thereof. A main shaft is provided with the target on its upper end and is supported by bearings in such a manner that it can rotate and move up and down. A plunger disposed at the periphery of the main shaft is magnetically attracted by an electromagnetic solenoid. When raised, the main shaft always faces a predetermined direction due to an action of permanent magnets. Hitting of the target can be detected by monitoring abrupt large fluctuations in current flowing through the solenoid during a period of time that the target is caused to appear above the table.
