  • Large capacity paper feeder for an image forming apparatus
    Patent number: 5882005
    Abstract: In an image forming apparatus, a large capacity paper feeder has a single pick-up roller capable of selectively feeding papers from an LCT (Large Capacity Table) or from a cassette removably mounted to the apparatus. The paper feeder, therefore, does not need a bulky paper feed unit for a cassette feed mode. In addition, a space for an LCT feed mode is not necessary above the pick-up roller, so that the height of the apparatus is not increased.
    Type: Grant
    Filed: May 22, 1997
    Date of Patent: March 16, 1999
    Assignee: Tohoku Ricoh Co., Ltd.
    Inventors: Yoshiyuki Araseki, Takenobu Kamada, Hitoshi Kimura
