Camera incorporated with a movable flash light device
摘要:
In the disclosed flash camera, a flash unit is movable between protruding and stowed positions, and a sensor senses whether a capacitor that flashes the unit is adequately charged. A switch and a control circuit enable the flash only when the unit is in the protruding position and the sensor simultaneously senses an adequate charge.
