Abstract
A lens barrel is associated with a frame body of a camera for advancing and retracting movements along an optical axis direction. A film accommodating chamber is located on the side outward from the lens barrel with respect to a direction normal to the optical axis direction. A motor is secured to the frame body, mechanical power of the motor being transmitted to the lens barrel via a gear train to move the lens barrel along the optical axis direction. The motor is located within a space defined by the lens barrel and the film accommodating chamber, such that an output shaft extends in a plane normal to the optical axis. The frame body has a path for insertion of a motor securing tool.
Claims3
A motor mounting structure for a camera, the camera comprising:
- i) a lens barrel associated with a frame body of the camera such that the lens barrel is capable of advancing and retracting along an optical axis direction,
- ii) a film accommodating chamber, which is located on the side outward from the lens barrel with respect to a direction normal to the optical axis direction, and
- iii) a motor, which is secured to the frame body, mechanical power of the motor being transmitted to the lens barrel via a gear train comprising a plurality of gears in order to move the lens barrel along the optical axis direction,
- wherein the motor is located within a space, which is defined between an outer surface of the lens barrel and an outer surface of the film accommodating chamber, such that an output shaft of the motor extends in a plane normal to the optical axis direction, and
- the frame body has a path extending perpendicular to the optical axis, through which a tool for securing the motor to the frame body by screwing is to be inserted.
