Abstract

PURPOSE: To extend a piezoelectric body in length and to make it more powerful and to prevent variations of a lens barrel and an increase a camera in width by forming the piezoelectric body of a power generating member in an arc shape by matching it with the shape of the lens barrel.
CONSTITUTION: The titled device is constituted in a partial arc or semi-arc shape centered on the optical axis of an exposing device 6. The device is also provided with the power generating member 1 of the bimorph piezoelectric body, which generates a deforming movement in the direction in parallel with the optical axis X, and a rocking member 3 which arranged in a position nearly symmetrical with the power generating member with respect to the optical axis Z, can rock centered on an axis X perpendicular to the optical axis Z. The member 3 is rocked by the power generating member 1. The rocking member 3 converts movement in parallel with the optical axis, which is caused in the power generating member 1, into a rocking movement centered on the axis. Thus the power generating member 1 can be made longer than the conventional but never introduces the deformation of the lens barrel or the increase in the width of the camera.
