  • the box is provided with a separation pawl facing the inside and located on each end of the upper side of the sheet feeding lateral side, the separation pawls being mounted to allow the box to move vertically to some degree.
  • the bottom surface of the box body is inserted into the space between the lower side and the bottom surface of the arm in order to limit the separation pawls from moving over a certain degree.
  • This invention relates to an automatic cut sheet feeding unit used in electrophotographic or various other copying devices or in simple printers.
  • This invention includes, further, the improvement of cassette means used in the automatic cut sheet feeding device.
  • An object of this invention is to provide a mechanism to dispense paper, one sheet at a time, assuredly and smoothly from such a cut sheet box.
  • This invention is directed to a device which automatically feeds the above-mentioned cut sheets effectively into a copying device etc. and does not require an auxiliary guide etc. even when the number of sheets has been reduced.
  • the device feeds the sheet extremely smoothly at all times, and allows the cut sheets and cassette to be easily loaded.
  • a cut sheet box with an open top is provided with a separation pawl facing the inside and located on each end of the upper side of the sheet feeding lateral side.
  • the separation pawls are mounted to the cut sheet box in such a manner as to allow the box to move vertically to some degree.
  • the sheet feeding lateral side of the cut sheet box is made separately from the box body, and arms are provided on both ends at right angles respectively, and the sheet feeding lateral side is loosely mounted on the box body.
  • a separation pawl is provided facing inward on each end of the upper side of the sheet feeding lateral side, the lower side thereof being bent along the bottom lower surface of the box body, and the bottom surface of the box body being inserted into the space between the lower side and the bottom surface of the arm in order to prevent the separation pawls from moving over a certain degree.
  • this invention does not require the separation of the sheet feeding side of the cut sheet box, and, allows the separation pawls to be provided with a stopper, which controls the sheet position of the sheet feeding side.
  • An intermediate plate which is smaller than the inside of the box body, is inserted into the box body and, between the intermediate plate and the bottom springs are provided, which are strong enough to push up, by way of the intermediate plate, a specified number of cut sheets, even when the number of sheets is reduced by consumption, and to press the sheets against the separation pawls with the proper force.
  • This invention offers several embodiments for the cassette mentioned above.
  • the following description is directed to an embodiment wherein the feed roller rotates and depresses the sheet only at feeding time.
  • the feed roller is supported by an arm provided with a shaft, and is positioned by the force of a spring etc. at a position spaced apart from the paper surface in the cassette box.
  • the feed roller may rotate continuously or just at the time of feeding the sheet. 1
  • the feed roller Upon receiving the feed signal, he arm rotates a certain angle and the feed roller is pressed on the upper surface of the stacked sheets.
  • the latter position of this feed roller is always constant, and is set in such a way that the lowest surface of the feed roller is slightly lower than the natural position which the uppermost sheet reaches when the stack of sheets is pushed up by the springs. Accordingly, the separation pawls are always in position to press the sheets by their own weight regardless of the height of the stacked sheets. In other words, the separating action is always the same even when the number of sheets is reduced and thus the feeding of a single sheet is performed with assurance.
