<p>PURPOSE:To prevent the influence of vibration, etc., from respective mechanism parts, to prevent malfunction, to improve the assemblability of the respective parts of a lens barrel and workability and to reduce cost by constituting a fixed member constituting the lens barrel so that it may be divided into plural units. CONSTITUTION:The part which is the fixed member constituting the lens barrel E is divided into plural units 5 to 7 such as a fixed barrel 10, a 1st fixed barrel part 31, and a 2nd fixed barrel part 43, the units are integrally connected by screwing, etc., so that the lens barrel 1 is formed. A focusing mechanism part 2, an image blurring preventing mechanism part 3 consisting of a shake preventing optical system L3 and an image blurring preventing driving mechanism 30, and a shake detection sensor part 4 consisting of a shake detection sensor 40 are respectively and individually assembled and disposed in the respective units 5 to 7. Thus, the direct influence of the vibration caused by the actuation of each driving part and the vibration caused by the actuation of an actuator itself in each driving part exerted on the sensor 40 is suppressed.</p> |
