Mirror drive apparatus incorporating a brake mechanism of an SLR camera |
摘要 |
A mirror drive apparatus incorporating a brake mechanism of an SLR camera includes a mirror pivoted about a mirror rotational shaft and swingable between a viewing position and a retracted position, wherein the mirror is biased to swing from the viewing position to the retracted position; a brake drum which rotates in association with a swing movement of the mirror; a mirror brake member including a brake shoe which is brought into contact with and disengaged from the brake drum; a mirror control cam driven by a motor to return the mirror, which is biased to swing from the viewing position to the retracted position, to the viewing position from the retracted position; and a brake lever control mechanism which makes the brake shoe contact the brake drum and moves the brake shoe off the brake drum by a rotating operation of the mirror control cam. |
