摘要： PURPOSE:To make a rocking range small and to open/close a shutter in a short time without changing the attaching position of a shutter blade. CONSTITUTION:This shutter is the shutter of a camera where the shutter blade 12 is arranged at the poststage of a 1st diaphragm 5 for incident light, a projection part 14 projected toward the 1st diaphragm 5 is formed at one part of the shutter blade 12. The incident luminous flux is intercepted just behind the 1st diaphragm 5 by the projection part 14. Therefore, the shutter is opened/ closed at a spot in a minimum luminous flux area, which is formed by the 1st diaphragm 5, and the action of the shutter is performed in a short time.

摘要： PURPOSE:To provide a film unit equipped with a lens having a release operation part whose cost can be more reduced by making the structure as simple as possible, unnecessitating an incorporation work and reducing the manufacturing cost. CONSTITUTION:An unexposed film is previously packed in the film unit equipped with a lens, and a photographic lens for exposing the film is installed on the front wall of the unit, a shutter mechanism for opening/closing a photographic aperture passing through the photographic lens and a shutter driving mechanism for operating the shutter mechanism are separately installed in the unit, and a shutter-releasing pressure part 40 for operating the shutter driving mechanism is installed on the top plate 12b of the unit so as to be positioned on the same plane as that of the top plate 12b. One end part of the pressure part 40 is elastically connected with the top plate 12b through an elastic connection part. The top plate 12b is provided with a cut-out part 45 which is formed on a part other than the elastic connection part by cutting the surrounding of the pressure part 40 out of the top plate, and the pressure part 40 is molded of synthetic resin integrally with the top plate 12b.

摘要： PURPOSE:To return a camera to the original mode to continue preparatory winding and photographing by closing a rear cover again unless a film is rewound in case of erroneous opening of the rear cover during loading of the film, by charging a mode switching means with a member interlocked with opening and closing of the rear cover. CONSTITUTION:When a cartridge is loaded and the rear cover is closed, a mode switching lever 306 is charged, and a mode changeover switch 300 is connected to a preparatory winding contact R, and a rear cover switch SC is turned off. A film detecting switch SF detects the presence of a film and is turned on, and a current is flowed through the rear cover switch SC, a normally closed contact NC of a relay switch RLS, a driving motor 2 and the preparatory winding mode contact R of the mode changeover switch 300 to execute preparatory winding. If frames of the film which are exposed to light by erroneous opening of the rear cover in the photographic mode are fed, a manual rewind switch SA is turned on to make the operation of a one-frame switch SO impossible, and thereby, driving of the driving motor 2 is continued till the film switch SF is turned off, and the film is wound into the cartridge.

摘要： PURPOSE:To protect an already photographed film by connecting a cartridge switch to a driving motor circuit of the preparatory winding mode in series with a driving motor and making a mode switching means and the driving motor unoperative when a rear cover is closed again even if the rear cover is opened during loading of the film. CONSTITUTION:A film detecting switch SF which detects whether a film exists or not, a mode changeover switch 400, and a cartridge switch ST are connected in series to a power source E and a rear cover switch SC which is turned off and on in accordance with opening and closing of the rear cover. If the rear cover is opened erroneously in the photographic mode, a mode switching lever 406 is moved to a preparatory winding mode position by the action of a charge lever 424, and the lever 406 is detained in the preparatory winding mode position by a detaining lever 416, and the mode changeover switch 400 is connected to the preparatory winding mode. Meanwhile, a projection 310 and a cartridge lever 304 are disengaged from each other in accordance with opening of the rear cover due to a rear cover spring member 312, and the cartridge switch ST is turned off, and therefore, preparatory winding is not executed.

摘要： PURPOSE:To pull out exposed film simultaneously with the work of taking out a battery and to improve working efficiency by using the cover of a film chamber also as the cover of a battery chamber. CONSTITUTION:The cover 6 of the film chamber for taking out a cartridge 3 in which the exposed film is wound is attached to the aperture part of the film chamber 2 so that it can be freely openable and closable to the edge part of a unit 1. A cap 6a being the cover of the battery chamber 4 is formed at the tip of the cover 6 of the film chamber so that it may project to the side. By opening the cover 6 of the film chamber in the case of taking out the cartridge 3 of the exposed film, the cap 6a is simultaneously opened to open the aperture 4a of the battery chamber, so that the battery 5 is taken out simultaneously with the film cartridge 3.

摘要： PROBLEM TO BE SOLVED: To provide a switch-switching device for detecting a different state or operation using one switch, and to provide a camera using the switch switching system for the opening and closing detection of a rear cover and the operation detection of an unwinding operation part.
SOLUTION: An operation member 27 is integrally formed of a sliding rear cover operation part 17 for opening and closing the rear cover, a push type unwinding operation part 18 for carrying out unwinding on the way of a film for the camera, and a cam part 39 for turning on/off a rear cover switch 43, in response to these operations. When the rear cover operation part 17 is slid upward, an operation member 27 as a whole is moved upward, a cam part 29 pushes one metal contact piece 43a of the rear cover switch 43 to be brought into contact with the other metal contact piece 43b so as to make the rear cover switch 43 to turn on. In addition, when an unwinding operation part 28 is operated to be pushed, a curved part 38 is deformed elastically, and the cam part 39 makes the rear cover switch 43 to turn on.

摘要： PROBLEM TO BE SOLVED: To prevent a film magazine from falling carelessly from the magazine chamber of a DIL system reverse loading type camera.
SOLUTION: A protrusion 9 for preventing fall is integrally molded on the inner peripheral wall of the magazine chamber 5. The film magazine 7 is loaded in a loading position shown by an alternate long and two short dashes line. When a back cover is opened while the base of the camera is turned downward, the magazine 7 begins falling, and the magazine 7's falling is stopped when the upper cap 7c of the magazine 7 is engaged with the protrusion 9 on the cartridge chamber 5 side. Then, the lower part of the magazine 7 is projected from a camera body. By holding the lower part of the magazine 7 with user's hand and drawing it out to the lower side, the outer periphery of the cap 7c gets over the protrusion 9.
