  • Patent number: 4928900
    Abstract: A cartirdge or cassette for containing light-sensitive web material for application to utilization apparatus is provided with mechanical encoding on one of the cartridge end caps, in the form of a series of protrusions and/or recesses. The protrusions or recesses are formed by injection molding in one of the exposed walls of the end cap and provide a binary code which, in cooperation with utilization apparatus, prevents the improper insertion and utilization of the cartridge. The code positions are formed during set-up of the mold in which the end cap is formed by injection molding by the selection of cooperation pairs of mold pins in recesses provided in the mold halves, to form either a recess or a protrusion in the form of a pin in each of four possible code positions. The protrusions have closed ends and are hollow, so that the breaking off of a protrusion by attempted improper utilization permits light to enter the interior of the cartridge through the protrusion and end cap.

  • Patent number: 4220405
    Abstract: An arrangement for setting camera functions in dependence upon a characteristic of film being used in the camera. The arrangement includes a manually operable setting knob which can be turned to a plurality of settings and is arrested in each by an arresting device. This knob is used when the film cassette employed in the camera has no film-characteristic (e.g., film speed) mark. When the cassette does have such a mark, the insertion of the cassette into the film chamber of the camera causes disengagement of the arresting device and automatic turning of the knob to a position corresponding to the detected mark. Since the knob is visible to the user it serves as an indicator of the film in the camera, whether the camera setting is manually or automatically made.

  • Patent number: 4055846
    Abstract: A camera has a cover member for opening and closing a film cartridge-retaining chamber, and a detecting member movable to effect automatic setting of the film sensitivity or automatic change-over of a filter. The film cartridge has a signal element on its side wall of a predetermined size which may be engaged by the detecting member when the film cartridge is charged into the camera for effecting the automatic setting of the film sensitivity or of the automatic change-over of a filter. After the detecting member has engaged the signal element, and thus tends to tilt the film cartridge, the detecting member is moved in a direction away from the signal element due to a closing operation of the cover member, or the detecting member is released from a force which urges the detecting member toward the signal element, thereby eliminating the influence of the force acting to tilt the film cartridge.
