ABSTRACT:
A camera has either a built-in flash unit or a removably attachable flash unit which is turnable between a retracted position and a projected position and which is provided with an illumination-angle varying mechanism. The camera includes a motor, disposed in a body of the camera, for driving the illumination-angle varying mechanism, and a transmission system, which transmits an output rotation of the motor to the illumination-angle varying mechanism. The transmission system includes a rotating wheel which has a central axis coincident with a turning axis of the flash unit. The flash unit may include a structure divided into at least three areas: a middle area, a first side area, and a second side area. A flash generating device is disposed in the middle area; a red-eye prevention lamp is disposed in the first side area; and a drive transmission system for driving the illumination-angle varying mechanism is provided in the second side area.
