Pistol Projects Pictures (Feb, 1938)
Pistol Projects Pictures
Pictures are “shot” onto a viewing screen by a novel flash-light gun recently introduced as a toy for children. As shown at the left, pulling the trigger operates a pawl to move, one frame at a time, an endless strip of picture film in front of a battery-operated lamp. Simultaneously, the trigger makes an electrical contact to light the lamp and project the picture onto the screen.
