Abstract
A flash device in which a mechanism for shifting a light emitting section up and down and a mechanism for changing over the light distribution angle can be automatically controlled by means of a single motor and which occupies a comparatively small spacing when mounted on a camera. The flash device includes a bidirectional drive motor mounted in a body member, and a shiftable member having the light emitting section thereon. The shiftable member is shifted by rotation of the motor in either direction between a retracted inoperative position and a projected operative position. The light distribution angle of the light emitting section is changed over by continued energization of the motor after the shiftable member is moved from the inoperative to the operative position. A friction mechanism is interposed in a motion transmitting mechanism from the motor to the shiftable member. The motor and the motion transmitting mechanism are disposed at a location within the body member at which they are located, when mounted on a camera, above a spacing sidewardly of a central portion of the camera in which a pentagonal prism is disposed.
