Abstract:
1. An imaging apparatus comprising: a mirror configured to advance into or retract from a photographic optical path; a shutter blade configured to close and open an aperture; a blade lever connected with the shutter blade; a blade return spring configured to urge the blade lever in a direction in which the aperture is opened by the shutter blade; a drive lever configured to press the blade lever in a direction in which the aperture is closed by the shutter blade; a blade drive spring configured to urge the drive lever in a direction in which the aperture is closed by the shutter blade; a first member configured to lock a position of the blade lever to cause the shutter blade to shift to a state of closing the aperture; and a second member configured to cause the mirror to advance into the photographic optical path at a first position and to cause the mirror to retract from the photographic optical path at a second position, wherein, the second member is driven from the first position to the second position after the first member has unlocked the blade lever so that the shutter blade is driven in the direction of opening the aperture by an urging force of the blade return spring before the mirror starts an operation for retracting from the photographic optical path.
