Abstract: In a film scanner capable of reading images from films of different forms, i.e., a cartridge film and a film strip, and arranged to be simply adjustable, image light from the cartridge film is reflected by a reflecting mirror to be projected on an image sensor which converts the projected image light into an image signal. Image light from the film strip is projected onto the image sensor to be converted also into an image signal with the reflecting mirror rotated counterclockwise away from its position by rotating a motor which moves a cam, etc. In manufacturing the film scanner, the position and inclination of the image sensor relative to the film strip are adjusted with the reflecting mirror retracted from its predetermined position, and a base plate on which the image sensor is mounted is fixed by an adhesive to a lens frame with the image sensor set in the adjusted position.

Abstract: A camera arranged to permit photographing by taking full advantage of a spurious telephoto shooting function irrespective of the current state of facilities of photofinishing laboratories is provided with an image plane frame change-over mechanism which acts in response to mode selection made by a mode change-over switch to effect change-over of the size of an image plane frame between a normal image plane frame having a normal image plane frame size and a spurious telephoto image plane frame having a size not exceeding 1/2 of the normal image plane frame size and a restricting member which causes a shooting image plane set by the spurious telephoto image plane frame to become containable within a range of film usable in taking a panorama shot. Therefore, in the spurious telephoto mode, a spurious telephoto shot is taken within the range of film for a panorama shot.

Abstract: This invention discloses an improvement of a filter apparatus for cameras and particularly discloses various arrangements for improving the filter apparatus for cameras in which, for example, an operating means for placing a filter in and taking it out of the optical path is provided so that the operating means automatically removes the filter from the optical path by stopping the operations of filter photography at the completion thereof. Thus, a photograph can be prevented from mistakenly being taken with the filter still in place in the optical path, and protective means for preventing damage of the filter surface is provided on the filter.

Abstract: A camera has a changeable picture frame forming means for changing the picture frame size and features the prohibition of actuating the changeable picture frame forming means during the use of one and the same roll of film.

Abstract: The disclosed camera changes between two focal lengths by bringing or taking a built-in attachment lens into and out of axial alignment with a master lens. A single electric motor serves as the drive source both for changing the focal length and effecting automatic focusing. The attachment lens is brought into axial alignment with the master lens for telephoto operation and taken out of axial alignment with the master lens for standard operation.

Abstract: An optical system shifting device for a camera in which an optical system is shifted in the direction of the optical axis by the driving force of a motor, wherein a first positioning member effects the positioning of the optical system in the direction of the optical axis independently of the driving force of the motor, a second positioning member effects the positioning of the optical system in a direction perpendicular to the optical axis of the optical system, and a switching member actuates the motor by giving an external force to the optical system, whereby the functional features as well as maneuverability of the optical system shifting device are improved.

Abstract: A barrel driving device for a camera including a distance adjusting ring having cam portions for axially moving a photographic lens barrel forward, ratchet teeth formed in the outer periphery of the distance adjusting ring, a ratchet arranged upon movement from an initial or first position to a second position to turn the distance adjusting ring in engagement with one of the ratchet teeth, and a pawl arranged upon engagement with one of the ratchet teeth to hinder the reverse movement of the distance adjusting ring, wherein there is provided a limiting member having an abutment surface against which the head of the ratchet abuts so that the ratchet is hindered from turning outwardly of the distance adjusting ring when it goes in the second position.

Abstract: A control signal generator for a camera arranged to control the aperture of a stop by the opening degree of at least two shutter blades; to detect the opening degree of the shutter by detecting, with a photo interrupter, openings provided in one of the shutter blades; and to form a control signal based on to the opening degree of the shutter thus detected. When the shutter is closed, a shutter blade other than the blade having the openings confronts the light emitting and receiving elements of the photo interrupter to block an optical path thereby. When the shutter begins to open, the optical path is opened and the photo interrupter generates a signal indicating commencement of the opening action of the shutter.

Abstract: In a vari-focal camera which has a photo-taking optical system including a main lens system and an auxiliary lens system and is arranged to be shiftable between at least two different focal lengths by moving the photo-taking optical system back and forth on a photo-taking optical axis in such a way as to cause the auxiliary lens system to move onto and out of the optical axis, a guide bar is arranged to allow a lens barrel unit which includes the photo-taking optical system, a shutter and a photo-taking lens focusing device to straightly move. The guide bar is fittingly engaged with a member secured to a camera body. The camera is further provided with an adjusting member for focusing the photo-taking optical system in each of preset positions in which the photo-taking lens has the different focal lengths.

Abstract: A motorized camera having a gear train between an electric reversible motor and a film rewind fork with a mechanism for transferring the driving torque from an intermediate gear of the train to move a member having function other than film transportation as the gear is out of mesh with the next one, wherein a mechanism is provided between the last gear of the train and the rewind fork so that only when the last gear has rotated by a prescribed angular distance, the fork starts to engage the supply spool of the film cartridge to rewind the film.

Abstract: A device for driving the axial movement of a photographic lens barrel of a camera including a distance adjusting ring having a number of cam portions of similar shape arranged successively on the front end of the ring to cooperate with a follower on the barrel, a ratchet mechanism for turning the ring from the initial or first to the terminal or second position of each cam portion, a rotor arranged in a magnetic field to drive the ratchet mechanism, and a circuit for controlling the current supply to the rotor. After an exposure has been completed, as the ring is further turned in the same direction, when the terminal end of the cam portion moves away from the follower, the lens barrel is set in the initial position of the next cam portion. The rotor control circuit is provided with a switch arranged to open after the lens barrel has moved some distance from the initial position, whereby the circuit is rendered responsive to the closure of the switch for stopping the current supply to the rotor.
