摘要： A lens holding frame holding a lens in a lens barrel is arranged, and a contact member extending therebelow is in friction coupling with a driving axis. By applying driving pulses having such a waveform that includes a moderate rising portion followed by an abrupt falling portion to a piezoelectric element, the holding frame is moved along the direction of the optical axis. An index provided at the holding frame is exposed through a slit of lens barrel, and from the position of the lens on the holding frame, information with respect to the distance to the object is displayed. Detection of the position of the holding frame is performed by a position sensor of ferromagnetic thin film magneto-resistive element type (MR sensor) so as to obtain positional information of the lens on the holding frame based on the detection signal, and the obtained information may be displayed on a liquid crystal or other display portion provided on the lens unit or on a camera body.

摘要： A zoom lens barrel based on the vari-focal optical system includes a zoom cam ring which is supported only rotatably about the optical axis and a focus cam ring which is supported movably only in the axial direction both fitted on a fixed tube inside a lens barrel. For the alteration of the lens focal length, the zoom cam ring is turned to carry out zooming, and for the focusing of an object, the focus cam ring is moved in the axial direction to carry out focusing, thereby preventing the interference between zooming and focusing caused by the movement of the lens sets. A drive mechanism based on a piezo-electric element is used to move the focus cam ring in the axial direction, thereby simplifying the structure and reducing the weight.

摘要： A sliding coupling mounted between a pair of separately rotational members, including a pair of coiled springs, which realizes no rotational delay at time of reversing a rotational direction of one of the rotational members. Each coiled spring has a projecting part extending radially outwardly from one end thereof. The pair of coiled springs are fictionally mounted on an outer surface of one of the rotational members with the circular parts and the projecting parts of the coiled springs being overlapped with each other so that the winding directions of the coiled springs are opposite to each other. The other rotational member has an engaging groove with which the projecting parts of the coiled springs are engaged without a space between each projecting part and a surface forming the engaging groove of the rotational member in each rotational direction. When the rotational direction of the one rotational member is reversed, the rotational direction of the other rotational member is also reversed with no rotational delay.

摘要： A structure for preventing an image being shaken when a vibration occurs in an optical system so as to stabilize the object. A compensating lens is incorporated in a third lens group of a lens barrel constituting the optical system. The compensating lens is allowed to move within the third lens group and only in a direction perpendicular to the optical axis. A pulse motor mounted on a fixed barrel drives the compensating lens. The rotation of the pulse motor is converted into the rotation of an interlocking lever. The interlocking lever is a straight bar having an uncircular sectional configuration. A driving lever having approximately the same configuration as the sectional configuration of the interlocking lever is slidably inserted thereinto. The driving lever rotates together with the interlocking lever. One end of the driving lever penetrates through the frame of the third lens group, thus contacting the head portion of a pin which presses the compensating lens. When the driving lever rotates, the compensating lens is pressed through the pin. At a position opposed to the pin, a plate urged by a leaf spring supports the compensating lens. A mechanism for driving the compensating lens is provided in x-direction and y-direction with respect to the compensating lens. When the driving lever rotates in the opposite direction, the compensating lens is moved to the initial position by the elastic force of the leaf spring.
