Abstract:
1. An optical device controller in the type of imitative gun comprising: a trigger-like portion, a barrel-like portion having a muzzle-like opening, a gas passage forming portion arranged at a rear end of the barrel-like portion for providing a gas passage formed therein, a grip portion including a gas chamber and a gas leading passage for leading a gas from the gas chamber to the gas passage, a movable valve provided on the gas leading passage for maintaining the gas leading passage open in response to movement of the trigger-like portion, an optical device positioned in the barrel-like portion in communication with the outside of the barrel-like portion through the muzzle-like opening, an operation controlling portion for shifting the optical device from an inoperative condition to an operating condition in response to the movement of the trigger-like portion, a sliding member having a pressure receiving portion positioned at the back of the barrel-like portion and subjected to gas pressure generated through both the gas leading pressure and the gas passage, said sliding member initially moving back along the barrel-like portion from a reference position with gas pressure acting on the pressure receiving portion and then moving forward to return to the reference position, and a movable member in operative relation with the operation controlling portion for moving together with the sliding member and enabling the operation controlling portion to shift the optical device from the inoperative condition to the operating condition whenever a backward movement relative to the reference position of the sliding member is initiated.
