Document Type and Number:
Japanese Patent JP2009271128
Kind Code:
A
Abstract:
To increase moving speed required when moving a mirror to a position on a photographing optical path from a photographic lens to an image sensor and a position deviated from the photographing optical path, and to reduce power consumption caused by the drive of a motor.
A mirror driving device moves the mirror 7 to a first position on the photographing optical path Q passing through the photographic lens 3 and a second position deviated from the photographing optical path Q, and includes a plurality of magnetic devices 31 to 34 moving the mirror by either or both of repulsive force and attractive force generated by magnetic force at least when starting moving the mirror 7 to the first position or the second position.
