Patent ID: 8131147

Claim:
A movement mechanism comprising: a base body disposed in an inner part of an outer case of an imaging device; a mover that is movable in a first movement direction with respect to the base body between a receiving position where the mover is received in a receiving concave portion formed in the outer case and a projecting position where the mover protrudes outward from the outer case, and has a locked portion; a pressing spring to press the mover from the receiving position toward the projecting position; a moving base capable of moving in a second movement direction between a lockable position to the base body and a lock release position; a lock lever that is supported by the moving base and can move rotatably between a lock position and an unlock position, can move integrally with the moving base in the second movement direction, and is engaged with the locked portion of the mover when the mover is moved to the receiving position, the moving base moves to the lockable position, and the lock lever moves to the lock position, so as to lock the mover; and a driver that is connected to the moving base and is a drive source for moving the moving base in the second movement direction, wherein when the moving base moves from the lockable position to the lock release position, an engagement of the lock lever and the locked portion of the mover is released and the mover moves from the receiving position to the projecting position due to pressing force of the pressing spring, wherein the first movement direction of the mover is approximately perpendicular to the second movement direction of the moving base, wherein a cam sliding portion is installed in the moving base, and wherein a cam portion is installed in the mover such that, when the mover moves from the receiving position toward the projecting position, the cam portion slides with the cam sliding portion and moves the moving base from the lock release position to the lockable position, wherein in the cam sliding portion of the moving base, an elastic deformation portion capable of being elastically deformed in a direction toward or away from the cam portion is installed, and wherein when the mover moves from the receiving position toward the projecting position, the elastic deformation portion of the cam sliding portion is elastically deformed in a direction where a pressing force is applied to the moving base in a movement direction from the lock release position to the lockable position.
