Abstract
Provided is a compact thin type optical unit provided also with a housing 2 having an mounting surface 31 for mounting an imaging device 18 on, an optical system driving device 5 for driving the optical system 3, a light quantity control member 16 for controlling a light quantity projecting on the imaging device 18 and a light quantity control driving device 6 for driving the light quantity control member 16, and the optical system driving device 5, wherein the light quantity control driving device 6 are arranged outside a same side of the mounting surface 31 so as to overlap each other in a direction perpendicular to an optical axis X of the optical system 3.
Claims18
An optical unit for projecting an image of a subject on an imaging device comprising:
- a housing having an mounting surface for mounting an imaging device on;
- a movable optical system;
- an optical system driving device for driving the optical system;
- a light quantity control member for controlling a light quantity projecting on the imaging device;
- and
