Patent number: 4200385Abstract: In the present invention, stopping-down, sector preliminary closure and lens shutter release are effected in association with an interlocking member of the lens. The difference between the amount of operation of the interlocking member effected when a camera with an electronic eye, hereinafter an EE control mechanism is operated is obtained by varying the amount of operation of the interlocking member, regardless of the pressure or absence of EE control provided by the EE control mechanism. The use and non-use of the lens shutter is switched depending on this difference. The relating means between the camera and the lens is substantially identical to the relating means between an ordinary interchangeable lens not having a lens shutter and an automatic aperture. Therefore, for switching between the lens shutter use and non-use, it is unnecessary to provide an additional relating means between the lens and the camera.Type: GrantFiled: July 6, 1978Date of Patent: April 29, 1980Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventor: Tetsuji Shono

Patent number: 4199243Abstract: A release mechanism for camera of the type to which a motor winding unit may be selectively coupled to carry out rapid sequence film exposure is disclosed. The release mechanism is a constructed as a mechanical AND mechanism two inputs of which are changes in position of two members disposed within the camera body. One of the two members is an interlocking member interlocked with the operation of the shutter button and another is a movable member which moves to a predetermined position at the time of completion of winding motion. Therefore, the mechanical AND mechanism can drive the shutter system of the camera only when the winding is completed and the shutter button is pushed down.Type: GrantFiled: September 11, 1978Date of Patent: April 22, 1980Assignee: Nippon Kogaku K.K.Inventor: Yoshiyuki Nakano

Patent number: 4199247Abstract: A photographic diaphragm of the iris type, having two sets or series of diaphragm leaves instead of the usual single set. Each leaf is relatively narrow in a direction radially with respect to the optical axis, thereby reducing the radial dimensions of the annual space necessary to receive the leaves when the diaphragm is fully open. During a closing down movement to a smaller aperture, both sets or series of diaphragm leaves swing inwardly simultaneously during the first part of a closing movement; then one set of leaves remains stationary while the other set continues to swing inwardly to close the aperture down to as small a size as desired. The two series of leaves are in separate planes slightly spaced from each other in the direction of the optical axis. The diaphragm is preferably of the spring back type, which will spring back automatically to a predetermined aperture after it has been opened wide for focusing purposes.Type: GrantFiled: June 12, 1978Date of Patent: April 22, 1980Assignee: Carl Zeiss StiftungInventor: Gerhard Schwarz

Patent number: 4182566Abstract: In a camera, a motion transmitting member has a wedge-shaped end portion inserted between a shutter release member and a shutter restraining member. Manual depression of the release member pivots the motion transmitting member, which moves the restraining member to free the camera shutter for exposure. A spring member urges the motion transmitting member to maintain its wedge-shaped end portion in mutual contact with the release and restraining members. The spring-urging automatically adjusts the position of the motion transmitting member between the release and restraining members to compensate for wear of their contacting surface portions and substantially prevents any lost motion or lag between manual depression of the release member and movement of the restraining member to enable shutter actuation. Following shutter actuation, manual movement of a film member causes an extracting member to remove the motion transmitting member from between the release and restraining members.Type: GrantFiled: January 6, 1978Date of Patent: January 8, 1980Assignee: Eastman Kodak CompanyInventor: James R. O'Reagan

Patent number: 4163613Abstract: A camera body houses a rotatable pinion disposed in engagement with a fixed rack for translation along the rack as the pinion is rotated. A manipulatable portion of the pinion exteriorly projects through a slot in the camera body, enabling the pinion to be manually rotated. A slide member rotatably supports the pinion and is supported within the camera body for translation by the rotated pinion in adjacent overlapping relation to the slot. In this way, the slide member maintains the slot substantially closed to dirt or other foreign matter during the various stages of rotation of the pinion. A control element, adjustably movable for focusing or exposure control, is operatively coupled to the slide member for movement by the slide member in response to manual rotation of the pinion. A visual indicator on the slide member is viewable through a window in the camera body for indicating the proper setting of the control element.Type: GrantFiled: January 27, 1978Date of Patent: August 7, 1979Assignee: Eastman Kodak CompanyInventor: David C.
