Title:
CAMERA DEVICE
Document Type and Number:
Japanese Patent JP2003029320
Kind Code:
A
Abstract:

To realize a reduction of the cost and a miniaturization of an actuator used to drive a light shielding member in a camera device.

This camera device is constituted of a stator 1 consisting of a disk type piezoelectric element and generating rotational driving force to a peripheral end face in response to feed, a rotor 2 press-contacting with the peripheral end face and performing rotation by the rotational driving force, the light shielding member for photographing 31 integrally formed with the rotor 2, and a control part directly driving the member 31 by controlling the feed of the stator 1. For example, the member 31 is a shutter blade. Or, the member 31 is a diaphragm blade. Or the member 31 is a diaphragm turret plate.
