<p>PROBLEM TO BE SOLVED: To provide a movable mirror-driving unit of a camera capable of performing mirror bound suppression without affecting position accuracy of a main mirror and a sub-mirror with a simple structure.SOLUTION: A movable mirror-driving unit of a camera comprises: a first buffer member which is moved by being pressed to absorb an impact when a main mirror turns from a retreat position to a finder light guide position; a second buffer member which is moved by being pressed to absorb an impact when the main mirror turns from the finder light guide position to the retreat position; and a third buffer member which is moved by being pressed to absorb an impact when a sub-mirror turns to a projection position accompanying the turning of the main mirror to the finder light guide position. When the main mirror is at the finder light guide position, and the sub-mirror is at the projection position, the first buffer member is held at a non-contact position to a main mirror support member by the second buffer member, and the third buffer member is further held at a non-contact position to a sub-mirror support member by the first buffer member.</p> |
