Claim:
1. An image pickup apparatus comprising: a semi-transparent mirror; a holding member that holds said semi-transparent mirror and is rotatably supported by a mirror box so as to move said semi-transparent mirror between a mirror-down position in which said semi-transparent mirror enters into a photographing light path and a mirror-up position in which said semi-transparent mirror is retracted from the photographing light path; a drive unit configured to rotate said holding member between the mirror-down position and the mirror-up position; a shading member that is supported on an object-side end of said holding member via a rotation shaft so as to rotate between a closed position that is close to said holding member and an opened position that is apart from said holding member; an urging member that is arranged between said holding member and said shading member and that energizes said shading member in a direction to open said shading member to said holding member so as to arrange said shading member at the opened position when said holding member is in the mirror-down position; and an engagement portion that is provided in the mirror box and that engages with said shading member in a vicinity of the rotation shaft when said holding member rotates from the mirror-down position to the mirror-up position so as to rotate said shading member toward the closed position against an urging force of said urging member, and so as to arrange said shading member in the closed position when said holding member reaches the mirror-up position.
