Abstract
PURPOSE:To drive a mirror smoothly, by driving a sub-mirror by a cam provided on a main mirror driving lever, in a mirror driving device of a single- lens reflex camera consisting of a main mirror and a sub-mirror. CONSTITUTION:A holding lever 10, a holder 6 for a main mirror 4, and a holder 20 for a sub-mirror 18 are installed to turning shafts 12a, 12b provided on a mirror box 2, turning shafts 8a, 8b on the holding lever, and shafts 22a, 22b planted on arm parts 6a, 6b of the main mirror holder 6, respectively. As for the sub-mirror, an angle to the main mirror can be adjusted finely by an eccentric pin 26 which can be adjusted. To a driving shaft 40 of a mirror driving arm, a cam 44 of S-end is installed so as to be opposed to a shaft to be driven, of the sub-mirror holder, and when driving the mirror, the sub-mirror is guided in the closing direction against the main mirror.
