Patent number: 6339510Abstract: A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.Type: GrantFiled: October 11, 1994Date of Patent: January 15, 2002Assignee: Minolta Co., Ltd.Inventors: Nobuyuki Taniguchi, Masaaki Nakai, Takanobu Omaki, Tokuji Ishida, Hisayuki Masumoto, Hisashi Tokumaru, Tsuneyo Metabi

Patent number: 4553817Abstract: An exchangeable lens assembly detachably mountable on a camera body having an automatic focusing device is selectively capable of either automatic focus adjustment by the operation of the automatic focusing device or manual focus adjustment by a manual operation. In two of the embodiments, the change-over between the automatic focus adjustment and the manual focus adjustment is made by operation of a change-over member provided on a stationary barrel separately from a manual focusing ring. A driven shaft coupled with a focus adjusting mechanism is disengaged from a driving shaft of the automatic focusing device in the case of the manual focus adjustment. In the remaining embodiments, a manual focusing ring rotatable and axially shiftable relative to a stationary barrel is axially shifted between an automatic focusing position and a manual focusing position for the change-over.Type: GrantFiled: April 4, 1983Date of Patent: November 19, 1985Inventors: Makoto Ando, Tsuneyo Metabi, Yukio Miki, Takeshi Egawa

Patent number: 4525037Abstract: A zoom lens assembly for use with a photographic camera having a capability of functioning two different modes one at a time. In one mode, the lens assembly is of a type having its aperture ratio variable with change in focal length, and in the other mode, it is of a type wherein change in aperture ratio resulting from the change in focal length is compensated for to give a uniform aperture ratio at all focal length settings. For this purpose, a unique change-over mechanism is built in the lens assembly for switching the lens assembly from one of the different modes onto the other of the different modes at the will of a photographer.Type: GrantFiled: June 8, 1983Date of Patent: June 25, 1985Assignee: Minolta Camera Kabushiki KaishaInventor: Tsuneyo Metabi

Patent number: 4344688Abstract: An interchangeable lens of the automatic present diaphragm aperture type for a single lens reflex camera includes a swingable actuating lever spring biased to an advanced position and retracted and released by a control member retracted and advanced by the camera mechanism respectively with the termination of the exposure and the initiation of an exposure. A diaphragm blade control ring is spring biased to fully open aperture position and is unidirectionally drive coupled to the actuating lever by a rod projecting from the ring into the path of movement of a projection on the actuating lever so as to follow the lever under the influence of the biasing spring and to disengage the projection upon the diaphragm reaching its fully open position thereby permitting further retraction of the actuating lever and so as to be engaged and positively advanced by the projection with the advance of the lever.Type: GrantFiled: March 18, 1980Date of Patent: August 17, 1982Assignee: Minolta Camera Kabushiki KaishaInventor: Tsuneyo Metabi
