    摘要: A lens mirror cylinder having first and second movable lens structures, constructed by assembling in a mirror cylinder a plurality of magnetic circuit means arranged on the outer periphery side of the second movable lens structure, guided so that it can move in the light axis direction of the lens, so as to face each other across the light axis, a first lens driving means for driving the first movable lens structure arranged at a position on the outer periphery side of the second movable lens structure in which the magnetic circuits are not arranged, and a lens diaphragm unit. By this construction, the space of the lens mirror cylinder can be effectively utilized, and a reduction of size of the lens mirror cylinder and the camera using the lens mirror cylinder is realized.

    摘要: A sliding base 7 is supported over main guide shaft 27 and auxiliary guide shaft 28, and has first and second bearings 31 and 32 supported on the main guide shaft 27, and a third bearing 33 supported on the auxiliary guide shaft 28. The third bearing 33 has a fulcrum P3 thereof positioned on a straight line L1 connecting a middle point P4 connecting fulcrums P1 and P2 of the first and second bearings 31 and 32, and a center of gravity G1 of the sliding base 7 supporting an optical block 5 and objective lens drive 6 thereon. Thus, sliding base 7 can be presented from being vibrated.
