摘要： A camera comprising a main body part with spaced film supply and film take-up chambers and an exposure opening located between the film supply and take-up chambers and configured for exposing an unexposed film frame, a metering pawl for engaging a film perforation during exposure of the film frame at the exposure opening, and a film winding take-up for moving an exposed frame in a film take-up direction from the exposure opening to the film take-up chamber, is characterized in that the metering pawl is supported to engage a film perforation between the exposure opening and the film supply chamber during exposure of a film frame at the exposure opening, and a tensioning spring urges the metering pawl substantially opposite to the film take-up direction in order to tension a film frame at the exposure opening. Since the film length between the metering pawl and the film winding take-up is longitudinally tensioned, the film frame is similarly tensioned at the exposure opening. Thus, the film tensioning positively acts to prevent frame shift during exposure of the film frame.

摘要： A photographic camera wherein a film metering sprocket undergoes respective cylces of rotation in each of two opposite directions when a filmstrip is advanced substantially a frame increment in reverse directions over the metering sprocket, and an operating element is actuated to perform a camera function when the metering sprocket is rotated a cycle in one of the opposite directions but is not actuated for such purpose when the metering sprocket is rotated a cycle in the other direction, is characterized in that the metering sprocket and the operating element are disposed in a coaxial relation and include one-way motion transmitting means which when the metering sprocket is rotated a cycle in the one direction engages to compel the metering sprocket to rotate the operating element continuously in the same direction but which when the metering sprocket is rotated a cycle in the other direction does not engage in order to permit the metering sprocket to rotate independently of the operating element.

摘要： In a camera loaded with a 110 type film cartridge a film drive mechanism is provided with a control circuit for controlling a drive motor. In the normal film wind up operation a high voltage is applied to the motor, and after the final frame has been exposed and when the trailing part of the film is being fed, the voltage applied to the motor is lowered by use of a time constant circuit.

摘要： A device for conveying a motion picture film has at least one uniformly distributed row of perforations. An unwinding toothed reel, which continuously unwinds the motion picture film from a film supply reel, a winding toothed reel that continuously winds the motion picture film onto a film winding reel, and a film feeding mechanism, which intermittently conveys the motion picture film, engage inside said perforations. In order to switch the film conveyance from three to four perforation holes per film frame, the rotational speed of the film conveying motor connected to the winding toothed reel and to the unwinding toothed reel, is increased by 4:3, whereas the multiplication of the film feeding mechanism, of the movement gearing or of a movement gearing element can be altered by three or four perforation holes per film frame in order to adapt to the conveyance of the motion picture film.

摘要： When a camera is loaded with a film cassette, information corresponding to the diameter of a film wind shaft with film wound thereon is detected by a film cassette type switch. An address of a ROM is designated by the shaft diameter information, and shaft rotation angle information corresponding to the designated address is read out from the ROM. The film wind shaft is rotated through an angle corresponding to the rotation angle information by the driving force of a pulse motor. When a fixed length of a film is wound on the film wind shaft, the shaft diameter information is updated, a new piece of rotation angle information is read out from the ROM in accordance with the updated shaft diameter information, and the film wind shaft is rotated to be wound with the constant length of the film in accordance with the updated rotation angle information.

摘要： A simple mechanism is provided for winding film in a film cassette in which a pawl engages a perforation in each film frame to actuate a film stop device which, in turn, disengages the pawl from the perforation to remove any force from the film during picture taking. Winding force is transmitted from a unidirectionally rotating film feed disc to a reciprocating link and then to a undirectionally rotating spool gear which drives the film spool.

摘要： A sub-miniature photographic camera with a housing elongated in a direction transverse to the optical axis, and having a lens window opening and a viewfinder window opening in the front edge of the housing, spaced from each other in the direction of elongation of the housing. A cover plate or blind plate is slidable within the housing from a position closing both openings to a position uncovering both openings. A manually operable member slidable on the housing in a direction transverse to the optical axis serves simultaneously to initiate movement of the cover plate to an open position, and to wind the film, and to tension or cock the shutter operating mechanism ready for making an exposure. After the film winding and shutter tensioning movement of the manually operable member, if the operator decides not to take a picture right away and therefore moves the manually operable member back to its initial position in order to move the cover plate to its closure position, the manually operable member becomes automatically disconnected from the film feeding parts, so that it will not cause further film feeding movement if the manually operable member is again moved in a film feeding direction in order to shift the cover plate to an open or picture-taking position, when the operator is ready to make an exposure.

摘要： A film feeding device for a camera including a rotatable center shaft member having a protrudent clutch pin, the center shaft being movable alone in the direction of its axis; a rotatable film feeding sprocket which has a slot to allow the protrudent pin to engage therewith and which thus moves together with the center shaft member when the center shaft rotates; a drive device which is provided with a clutch groove to allow the protrudent pin to engage with and disengage from the clutch groove, the drive device being arranged to rotate in response to a film winding operation. When the center shaft shifts to one side defined by the slot, the protrudent clutch pin comes to engage with the clutch groove to cause the sprocket to rotate in response to the film winding operation. When the center shaft shifts to the other side, the protrudent clutch pin is disengaged from the clutch groove to permit free rotation of the sprocket. Thus, rotation of the sprocket is controlled by means of the single protrudent pin in such a manner as to minimize variation in spacing between one photographed picture and another.
