    摘要: A time-sharing drive apparatus for a camera having a plurality of motors includes a motor drive control system which alternately drives the motors in a time-sharing control. When the camera includes a zoom lens provided with a first stationary lens group, a second movable lens group and a third movable lens group, the motors are composed of a first motor which opens and closes a diaphragm of the zoom lens, a second motor which moves the second lens group, and a third motor which drives the third lens group. The motor drive control system which drives the first, second and third motors is controlled via a time-sharing system.

    摘要: A drive apparatus for a zoom lens barrel having at least two movable lens groups, one of which is used also as a focusing lens group, comprising a pair of lens frames which respectively hold the two movable lens groups, a pair of driven pins which are integrally provided on the lens frames, a drive cam plate which is provided with a pair of cam surfaces which engage with the corresponding driven pins and which is rotatable about an axis, a drive mechanism which includes a motor for driving the drive cam plate, and a detection mechanism which detects the angular position of the drive cam plate. One of the cam surfaces that corresponds to the movable lens group, other than the focusing lens group, is defined by a stepped cam surface having discrete sections which are adapted to set the focal length discretely, so that no movement of the movable lens group takes place in the range of the angular position of the drive cam plate corresponding to the discrete sections. The other cam surface that corresponds to the movable lens group that functions not only as the zooming lens group but also as the focusing lens group is defined by a continuous cam surface which is adapted to move the movable lens group continuously when the drive cam plate is rotated in accordance with the object distance. The stop position of the drive cam plate during the zooming operation and the angular position of the drive cam plate during the focusing operation is controlled by the detection mechanism of the angular position of the drive cam plate.

    摘要: A lens position adjusting method for a zoom lens includes at least two movable lens groups, one lens group being primarily utilized for focusing and the other lens group being primarily utilized for magnification, wherein an object at a predetermined distance is in-focus when each movable lens group is positioned at each of respective initialized positions thereof with the zoom lens being set at a first focal length, and wherein each movable lens group is moved to vary magnification in accordance with a moving amount from the initialized positions of the movable lens groups. The lens position adjusting method includes: arranging a testing object at a position corresponding to a predetermined distance from the zoom lens; arranging a focal point detecting device at a reference focal plane or in the vicinity of the reference focal plane of the zoom lens; moving each movable lens group to each position at the first focal length; moving each movable lens group along an optical axis of the zoom lens so that a lens moving amount of each movable lens group is detected when a sharp image of the testing object is formed on the focal point detecting device via the zoom lens; making each of the positions of the movable lens groups as provisional initialized positions after completion of movement by the lens moving amount from the initialized positions; moving each movable lens group from the provisional initialized positions to positions at a predetermined focal length; detecting the lens moving amount by moving the movable lens group being chiefly utilized for focusing; obtaining a defocus amount from the lens moving amount; and obtaining an adjusting amount according to the defocus amount detected at given plurality of focal lengths so that each position of the movable lens group at which the in-focus state with the testing object is obtained at the first focal length serves as each adjusted initialized position.
