Abstract
A camera includes a fixed first mirror for both reflecting a light flux and transmitting the light flux therethrough, a second mirror for reflecting a part of the light flux transmitted through the first mirror toward a particular device, the second mirror being capable of moving between a non-exposure position and a mirror-retracted position, and a light blocking member movable in interlocked relationship to a movement of the second mirror in such a manner that, when the second mirror is located at the non-exposure position, the light blocking member is located at a light blocking position at which the light blocking member blocks at least a part of the light flux transmitted through the first mirror, and, when the second mirror is retracted to the mirror-retracted position, the light blocking member moves to a retracted position at which the light blocking member is retracted from the light blocking position.
