摘要： A camera having a detection assembly and method are capable of detecting a top edge or a bottom edge of film. The camera includes a film detection assembly positioned within a camera body to detect one of the top edge and the bottom edge of the film. The film detector assembly includes a force detection assembly that detects a force exerted by one of the top edge and the bottom edge of the film. The film detection assembly also includes a film indication assembly to indicate the presence of film within the camera. The film indication assembly is connected to the force detection assembly. The film indicator assembly includes a switch assembly that opens and closes in response to the absence or presence of film within the camera.

摘要： A cam drive mechanism includes: a cylinder in which a cam groove is formed from one end face of an inner circumferential surface toward another end with a forming mold; a drive target object that comprises a cam follower to engage in the cam groove and is linearly driven along a rotational axis of the cylinder as the cylinder rotates; and a pressing member that presses the cam follower against a cam surface constituting a side surface of the cam groove. The cam surface is formed to have varying gradients so as to enable adjustment of an extent of displacement of the drive target object per unit of rotational angle by which the cylinder rotates and the cam groove is formed in a shape that allows the forming mold to be extracted from the cylinder through rotational extraction.

摘要： A camera having a lens barrier unit that opens without encountering obstructions in response to the operation of an operating member and without increasing the size of the lens barrel of the camera. The lens barrier unit covers the front surface of a photographic lens in a closed position, and moves clear of the front surface of the photographic lens in an open position. A sliding member, which is a separate member from the operating member, mechanically drives the lens barrier unit to an open position in response to the movement of an operating member by means of the operation for photographic preparation (e.g., when the camera is switched ON), and drives the lens barrier unit to a closed position, by coupling to the movement of the photographic lens unit while moving from the extended position to the retracted position (e.g., when the camera is switched OFF). The camera may include a finder optical system for visually recognizing an image of an object, with the sliding member disposed in the vicinity of a film aperture. The slide member is disposed in a face-to-face position to the finder optical system with the film aperture being interposed therebetween.

摘要： In a camera, there is a requirement for ensuring the timing of opening and closing a film cartridge light cutoff door when a cartridge chamber lid is opened and closed, and moreover for lightening the operational force for opening and closing the cartridge chamber lid. In view of these requirements, the camera according to the present invention includes a cartridge chamber into which a film cartridge which comprises a light cutoff door is loaded, a cartridge chamber lid which is selectively opened and closed so as respectively to communicate the cartridge chamber to the exterior or to isolate the cartridge chamber from external light, and a door opening and closing mechanism which exerts opening driving force upon the light cutoff door so as to open it, after the cartridge chamber has been isolated from external light by closing operation of the cartridge chamber lid. Preferably, the door opening and closing mechanism comprises an energy storage mechanism which stores energy from the cartridge chamber closing operation in order to open the light shielding door of the cartridge. The opening of the light cutoff door is started only after the cartridge chamber has been isolated from external light by closing operation of the cartridge chamber lid.

摘要： A high magnification zoom lens barrel including a drive ring having a short length in the optical axis direction to permit a compact camera configuration. The zoom lens barrel includes a first lens group support member to support a first lens group, and a second lens group support member to support a second lens group. The drive ring advances and withdraws the first lens group support member in the optical axis direction as the drive ring itself advances or withdraws in the optical axis direction as it rotates. The drive ring drives the first lens group support member with helicoids. A drive cam member is driven by the drive ring to rotate so that as the drive cam member rotates, it advances and withdraws the second lens group support member relative to the first lens group support member. A second drive ring is inserted into the drive cam member and rotates relative to the drive ring and is able to move in unison with the drive ring in the optical axis direction.

In one embodiment of the camera, a display unit is located on the upper surface of the camera body, and has a portion thereof, such as its drive mechanism at least partially positioned in a space formed between a light projection unit and light receiving of the camera's rangefinder device. In another embodiment, the camera has a mounting board of the required size for holding constituent control circuit components of the camera located in the camera body with attention to the location of the board in relationship to the cartridge compartment and other camera components to provide for a more compact design. A rigid mounting board is used as the mounting board and is located and incorporated within the camera body at the upper, inside portion of the camera body, in contact with the upper end of a reverse loading type cartridge compartment, and extending over a photographic lens barrel and to the upper side of a spool compartment. At least one or more camera components is arranged in a vacant space formed between the mounting board, the photographic lens barrel and the spool compartment. Furthermore, with the rangefinder device and a photometer device both mounted on the mounting board, a portion of the viewfinder unit is located on the lower side of the mounting board.
