  • Patent number: 7269834
    Abstract: A disc type recording and/or reproducing apparatus automatically performs the opening and closing of a shutter provided on a cartridge housing an optical disc in its case, and prevents the above-mentioned opening and closing mechanism from affecting the cartridge after an end of loading. When a DVR cartridge (51) is drawn into a recording and reproducing position by means of a tray (13), a shutter opening and closing mechanism (65) arranged on the side of the apparatus is relatively moved with regard to the cartridge (51). Thereby, shutter plates (100) of the cartridge (51) are opened or closed. Then, after the shutter plates (100) are completely released, the shutter opening and closing mechanism (65) is retracted by means of a cam (85) to be away from the cartridge (51).

  • Patent number: 7137129
    Abstract: A disk drive apparatus includes a casing having an upper plate; and a tray. The upper plate includes an arm having an attracted member fixed thereto. When the tray moves from a protruding position to a recording-and-playback position, since engagements of the arm and the tray are engaged with each other, the main body of the arm swings, and the attracted member serves as a chucking position facing a chucked portion of the disk-shaped recording medium placed on the tray. When the tray moves from the recording-and-playback position to the protruding position, since the engagement of the arm is detached from the engagement of the tray, the main body of the arm swings, and the attracted member serves as a retracting position retracting above the chucked portion of the disk-shaped recording medium.

  • Patent number: 5796465
    Abstract: An automatic film development apparatus includes a cartridge case for carrying a group of film cartridges loaded with undeveloped films. A feeder unit stores a plurality of the cartridge cases and delivering them one by one to an unloading station for unloading sheets of undeveloped film from respective film cartridges in the cartridge case. The undeveloped film sheet is rewound at a rewinding station into a takeup cartridge. A splicer unit joins one end of the undeveloped film sheet from the takeup cartridge to a short film leader supplied from a film leader supply unit for feeding short film leaders one at the time. A development unit developes the undeveloped film sheet joined to the short film leader. A separator unit separates a developed film sheet from the short film leader. The developed film sheet separated from the short film leader is loaded at a loading station back into its film cartridge.

  • Patent number: 5778510
    Abstract: A method and apparatus for attaching and detaching a filmstrip to a film cartridge having a take-up spool rotatably mounted therein. The cartridge has an access opening for allowing film to be inserted or removed from within. The apparatus includes means for positioning the film cartridge in a predetermined position. An attachment tool is rotatably mounted to the mechanism for movement about a pivot point. The attachment tool has a generally arcuate guide member. A mechanism is provided for moving the attachment tool from a non-engaged position to a first engaged position such that a portion of the attachment tool extends into the access opening for engaging the filmstrip to the attachment tool and for moving the tool to a second engaging position for allowing the filmstrip to engage the spool. The mechanism is further provided for moving the attachment tool in a radial direction while the attachment tool extends into the access opening.

  • Patent number: 5565953
    Abstract: Extra printing is made possible during a set of ordinary processing operations such as film development and printing. A film is developed and dried while being fed by a leader attached thereto. After cutting the leader from the film, it is fed to the printing unit to print the images on the film onto photographic paper. A plurality of film stocking units are provided in a path from the film drying unit to the printing unit. Each stocking unit can selectively stock a single film or allow it to pass without stocking. A second film stocking unit can move laterally to change the film track. If a film requiring a long exposure time is present in the printing unit, the subsequent films that have been developed and dried can be stocked in the other film stocking units. Thus, continuous film developing operations are not interrupted.

  • Patent number: 5461449
    Abstract: The leader attached to a web of film is cut from the film while processing the film in a photographic processing machine. Before feeding the film to the printing unit, the leader is separated from the film. At a turning point where the film feed direction extending from the film drying unit to the printing unit changes, the film is fed straight ahead and the leader is cut off the film by a cutter. The film is fed back in a reverse direction and its end is turned up by a guide. When the printing unit gets vacant, the film without the leader is fed into the printing unit.

  • Patent number: 5455653
    Abstract: The films are developed and printed continuously and automatically even if the film feed direction in the film processor and the one in the printer are not in the same vertical plane. A film stocking unit is provided downstream of the film driving unit. The film stocking unit is movable to a position aligned with the film feed path extending to the printing unit. This increases the freedom or flexibility in arranging the film processor and the printer.

  • Patent number: 5444514
    Abstract: A photographic processing apparatus capable of printing films having different widths. An exposure unit for printing film images on photographic paper has a negative mask to guide the movement of the films. The negative mask is provided with a plurality of film guide paths which correspond to widths of the films. A transfer unit is provided to move the negative mask in a direction perpendicular to the feed direction of the film. Along the film feed path toward the negative mask are provided sensors to detect the film size. Printing is carried out in such a manner that after the film size has been detected by the sensors, the transfer unit is controlled by the signal from the sensors to bring one of the film guide paths which corresponds to the film size into alignment with the exposure axis.
