Virtual bullet charging device for gun game machine
 A gun game machine from where a player takes out and holds a model gun to play a game. When the number of operations of a trigger lever (6) attains the preset number of times, the game is stopped and, at the same time, a solenoid (20) operates to disengage a boss (23) of a lever (19) from a recess (22b) of a advance and retreat member (15) and the advance and retreat member is ejected down by the effect of a spring (24). When the player pushes up the advance and retreat member (15) to set, a sensor (16) detects the pushing action and resets the trigger count value for enabling the game to continue. The action of pushing up the advance and retreat device (15) is similar to the real action of loading a cartridge into a real gun and the player can enjoy a game having realism.
