    • A camera of a preliminary winding type in which a film in a patrone is previously taken out from the patrone to roll it round a spool and, each time one frame photographing is completed, the film is rewound into the patrone by one frame in photographing. The camera comprises a motor, a preliminary winding mechanism, a frame-by-frame rewinding mechanism, a focal length varying mechanism, first and second planetary clutch mechanisms, and an engagement mechanism for locking the first planetary clutch mechanism, and is capable of switching the power transmission to the preliminary winding, frame-by-frame rewinding and focal length varying mechanisms by changing the direction of rotation of the motor.

    • A printing head for ink-jet printing comprises at least one ink-flow passage in the form of a hollow chamber and at least one ink-jet nozzle coupled to the ink-flow passage. The hollow chamber has a substantially uniform depth over substantially the entire area thereof. Preferably, the head comprises at least two laminated sheet-like members, one of the members having a hollow formed therein to comprise the ink-flow passage, and the other of the members having at least one nozzle formed therein. The head further comprises a flexible wall in communication with the hollowed chamber and a piezoelectric transducer connected to the flexible wall for producing ink-jetting pressure changes in the hollow chamber. Also disclosed are multi-nozzle printing heads with the chambers arranged in a circular configuration, and stacked double and triple decker arrangements.

    • A decorative frame that may be made of metal is arranged at the periphery of a manual operation button, and the manual operation button with decorative frame are designed so that they may be fixedly attached to the exterior cover of a camera body within an opening in the cover. More specifically a structure of a manual operation button is disclosed that includes: a decorative frame having an exterior portion that will not fit within the opening and an interior portion that will fit within the opening; a manual operation button positioned within an inner periphery of the decorative frame; and a holding member that is installed within the camera body, with a portion of the holding member abutting the inside surface of the camera body exterior cover and a portion of the decorative frame abutting the outside surface of the camera body exterior cover so that the decorative frame and holding member, when assembled as a unit, envelope the rim portion of the opening so as to attach the decorative frame and the holding member to the cover. The holding member holds the manual operation button so that it may be depressed to various positions when operating the camera.
