Claims (1)

[Scope of utility model registration request] It can be rotated around the shooting aperture of the camera body,
A printed coil is provided that cooperates with a permanent magnet provided in the camera body, and is driven to rotate in one direction or the opposite direction by applying a positive or negative control current from the sequential operation control circuit of the camera. a shutter blade drive movable element, which is rotatable around the photographing aperture of the camera body, and a printed coil that cooperates with the permanent magnet provided in the camera body; an aperture and lens drive movable element that is rotationally driven in one direction or the opposite direction by being supplied with a positive or negative control current from the aperture and lens drive movable element; a lens distance adjusting means for adjusting the lens shooting distance from a central commonly used intermediate distance to a long distance or a short distance by rotating the aperture and lens drive movable element in one direction or the opposite direction; The child is normally elastically biased to adjust the lens adjustment distance to the central commonly used intermediate distance, and is guided by the camera body so that it can reciprocate in one direction and the opposite direction from the central position. an aperture set lever that is attached to the aperture set lever and is elastically biased so as to be normally held at the center position; one end is pivotally attached to the aperture set lever, and the aperture set lever is in the center position; an interlocking lever whose other end is elastically energized so that the aperture and lens drive movable element is engaged with the aperture and lens drive movable element when the aperture and lens drive movable element is in the central position; an aperture pivotally supported on the body and operatively connected to the aperture set lever, the aperture having an intermediate aperture formed in the aperture aligned with the aperture in the camera body when the aperture set lever is in the central position; the diaphragm is pivoted to the camera body so that when the diaphragm set lever is moved in one direction or the opposite direction, a large diaphragm aperture or a small diaphragm aperture formed in the diaphragm is aligned with the aperture in the camera body; An iron piece lever is provided with an arm that presses the interlocking lever to separate it from the diaphragm and lens drive movable element, and a suction piece that cooperates with a holding magnet provided on the camera body. is elastically biased away from the interlocking lever, and when the holding magnet is energized by a control current from the control circuit, it attracts the suction piece and pivots the iron piece lever. the arm of the iron lever, which is formed on the aperture set lever, and is configured to press the arm against the interlocking lever to separate the interlocking lever from the diaphragm and lens drive movable element; the diaphragm set lever is releasably latched and held in that position when the holding magnet is energized; The aperture adjustment is first performed via the interlocking lever and the aperture set lever by the first rotation of the aperture and lens driving movable element while it is locked to the movable element;
The energization of the holding magnet causes the iron piece lever to be operated under suction, and the interlocking lever is disengaged from the diaphragm and lens driving movable element, and the diaphragm set lever is locked at its adjustment position to maintain the diaphragm adjustment state. An actuator for a camera, characterized in that the lens distance can be adjusted by a second rotation of the diaphragm and the lens drive movable element.
