1. Field of the Invention
The present invention relates to an actuator and a blade drive device for a camera.
2. Description of the Related Art
Conventionally, there has been known an actuator used for driving a shutter blade employed in a camera, and composed of a rotor, a stator, a coil for exciting the stator, and an outputting member for transmitting the rotational movement of the rotor to the shutter blade. Japanese Unexamined Patent Application Publication No. 2004-309531 discloses a device in which a rotor and a drive pin, serving as an outputting member, are integrally formed.
However, in the case where the rotor and the drive pin are integrally formed, it is difficult to change the positional relationships between the rotor and the drive pin whereas it is effective for downsizing. Therefore, it is difficult to change an angular position of the drive pin relative to the rotor according to a design variation.
