Holder Moved Parallel To Plane Of Sheets Patents (Class 271/164)
  • Patent number: 4660823
    Abstract: A sheet feeding device for a business machine includes a cassette and a cassette receiving station which cooperate to move sheets in the cassette toward a sheet feed roll after the cassette has been fully inserted and which also cooperate to move sheets in the cassette away from the sheet feed roll immediately before the cassette is withdrawn. Two projections extend from opposite sidewalls of the cassette and cooperate with grooves in the receiving station for facilitating cassette insertion and removal and for locking the cassette in place. Sheets in the cassette rest on top of a pressure plate. A pressure arm in the receiving station moves in an opening in the bottom of the cassette below the pressure plate to move the latter, thereby raising or lowering the sheets. A lug formed on the cassette engages an operating arm for the pressure arm upon insertion of the cassette.

  • Patent number: 4285510
    Abstract: A sheet feeding cassette which is capable of receiving manually inserted sheets is disclosed to eliminate the need to provide a copying apparatus with a device for receiving manually inserted sheets when the copying apparatus uses a sheet feeding cassette for sheet feeding. For readily receiving manually inserted sheets when the cassette is in position in the copying apparatus, the cassette includes a pressure plate responsive to the action of a sheet feeding pressure applying member, an upper lid capable of opening and closing even when the cassette is in position in the copying apparatus, and a member operative to cause the sheet feeding pressure applying member to act or stop its action in conjunction with the opening and closing of the upper lid. Sheets other than those which are usually contained in the cassette can be readily and positively manually fed readily and positively to the copying apparatus as desired for the purpose of producing copies.

  • Patent number: 4245835
    Abstract: A film storage device that is placed between an X-ray film cassette and X-ray film processor. The device is capable of storing three X-ray films at a time and enables an operator to reduce the waiting time for a typical set of three films per patient to be made available.Each film drops from the cassette into a light tight enclosure where it engages the nip of a S shaped system of rollers and belts. The film is carried fast to the end of the belt system where a curved plate and roller system delivers it to a slower travelling set of rollers which are part of the processor. The curved plate and rollers ensure that the X-ray film is appropriately curved and in compression as it awaits processing. An electrical indicating device on the processor is connected electrically to a switch on the fast S shaped roller system. The operation of these controls ensures that the delivery of film to the processor can be halted if necessary while the first film is being processed.

  • Patent number: 4245830
    Abstract: A sheet feeding unit includes a stack elevator which raises the top of a supported stack of sheets to infeed height. A sensor senses the position of the top sheets of the stack, to ascertain whether these exhibit improper left or right offset. Depending upon the magnitude and size of the sensed offset, the stack elevator is correctively shifted, to minimize offset at the top of the stack. Although the sensor is located to only one side of the stack, not at both sides of the stack, it is capable of sensing offset in both left and right directions. When the elevator is lowered, for the laying in of a fresh stack, it is automatically brought to a centered position.
