放電発光器の照射角切換装置。 In the illumination angle switching device for a flash discharge light emitting device configured to change the illumination angle by moving a light emitting unit consisting of a flash discharge tube, a reflector, etc. along the optical axis direction of a lens optical system, the light emitting unit is moved to a predetermined position. a drive mechanism including a spring member that applies a moving force to constantly move the light emitting unit back to the first position; an electromagnetic actuator that drives the light emitting unit to move toward the second position against the moving force of the spring member;
and a cam locking mechanism that locks and holds the light emitting unit moved to the position and releases the lock when the light emitting unit receives a driving force from the drive mechanism at the second position, and the light emitting unit is moved to the second position. 1. An illumination angle switching device for a flash discharge light emitting device, characterized in that the illumination angle can be changed to two stages: a telephoto illumination angle and a wide-angle illumination angle by moving the illumination angle to a first and second position.
