ABSTRACT:
This specification discloses a sheet feeding device for feeding sheets from a sheet supporting bed such as a cassette or a deck, and more particularly a sheet feeding device having a sheet supporting bed holding sheets thereon and adapted to be removably mounted at a predetermined position in an image forming apparatus, a rotatable member for contacting the sheets on the sheet supporting bed and feeding the sheets when the sheet supporting bed is mounted at the predetermined position in the image forming apparatus, support means for supporting the rotatable member for idle rotation by a predetermined amount in a forward direction and a reverse direction, and intermittent means for intermittently connecting the support means to a drive source. The sheet supporting bed includes, for example, a cassette type one which can be perfectly removed from the image forming apparatus or, for example, a drawing type one which can be pulled out and inserted relative to the predetermined position while remaining engaged with the image forming apparatus.
