Abstract: An indicated state changing pin which abuts indicating pieces of a cartridge, which indicate the state of a photographic film accommodated within the cartridge, and bends the indicating pieces, wherein a proximal end portion of the indicated state changing pin is formed larger than a distal end portion of the indicated state changing pin. Therefore, since the indicating pieces are bent while abutting the indicated state changing pin, even if the moving speed of the indicated state changing pin is constant, the indicating pieces are bent slower than the case of using a linearly-formed straight pin. As a result, separation of the indicating pieces from the cartridge is prevented, and the indicating pieces are reliably bent to the necessary depth.

Abstract: The camera of this invention includes a parking mechanism that ensures a visual exposure indicator of an APS film cassette is in the parked position prior to removing the film cassette from the camera.

In a preferred embodiment, the parking mechanism includes a pin that engages the rotatable wheel after the film has been rewound into the film cassette and the wheel has been rotated sufficient distance to ensure that the visual exposure indicator moves to the parked position. When the pin engages the rotatable wheel, the pin prevents further rotation of the rotatable wheel. This indicates to the camera user that the visual exposure indicator is in the park position. The wheel may include a cam slot into which the pin travels as the film is being rewound into the film cassette.

Abstract: In a cartridge chamber of a camera is disposed a photoreflector to read a bar code formed on a disk attached to an end of a film spool. When a cartridge is loaded, the film spool is rotated more than one round in the direction to rewind the film. The photoreflector starts to read the bar code when supply of a driving force to rotate the spool is started. The leading part and the trailing part of the output signals of the photoreflector are compared in the reverse direction to find a point where signals corresponding to the constant rotation of the disk begin. The signals preceding the point are discarded and the initial position of the disk before it is rotated is determined based on the length of the signals truly representative of the bar code while the disk is rotating at the constant speed. Use condition of the film, unexposed, fully exposed, partly exposed or already developed, is judged from the initial position of the disk.

Abstract: In an apparatus having a film condition judging device which judges a film condition based on data obtained by reading out bar codes of a bar code disk equipped on a film cartridge, wherein the bar code disk is initially stopped at a predetermined rotational position in response to the film condition, signals which are output from a sensor, are detected at plurality of times during a bar code disk rotation, and so inclinations in changes of the sensor's output are detected, thereby an error signal is distinguished from a correct signal according to the inclinations in the changes. Further, a sensor's output as a correct signal is counted, then the used condition of the film is judged based on the counted value of the sensor's output. Thus, even if there occurs an unstable rotation of the bar code disk, which brings the error signal, the film condition can be correctly judged by one sensor.

Abstract: A camera uses a film cartridge, which has an information recording disk which is rotatable integrally with a cartridge spool shaft and represents information inherent to a film, and feeds the film leading end portion from the cartridge by using a driver.

Abstract: This invention is applicable to a camera having a cartridge chamber into which a film cartridge is detachably insertable along its axis direction. The camera is equipped with a cartridge-load detection switch for outputting a load signal when the cartridge is loaded in the cartridge chamber, and outputting a non-load signal when the loaded cartridge is drawn out from the cartridge chamber by at least a predetermined amount. When the photographed cartridge is partially drawn out from the cartridge chamber and then reloaded into the cartridge chamber as it is, the output of the load signal is continued if the draw-out amount is below the predetermined amount, thereby preventing an erroneous judgment that a new cartridge is loaded into the cartridge chamber. Therefore, for example, the double exposure can be prevented.

Abstract: A device (e.g., a camera) loaded with a film unit operates to detect a characteristic of the film unit, such as the state of an information part of the film unit.

Abstract: An Indicator device for use with a web of material having perforations therein of a first pitch along an edge incorporates a wheel having a plurality of teeth that have a pitch that is less than the pitch of the perforations in the web of material. A spring urges the wheel into contact with the web of material such that at least one tooth on the wheel engages a perforation on the web of material. As the web and the wheel move relative to each other when a tooth is aligned with a perforation, the movement of the web of material then rotates the wheel until the tooth disengages with the aligned perforation. When a tooth is not aligned with a perforation on the web, the wheel and its teeth slide on the web of material until a tooth is aligned with a perforation. The diameter of the wheel and the associated teeth translating into the pitch between the teeth can thus be much smaller than a wheel with teeth having the same pitch as the perforations on the web material.
