ABSTRACT:
The present invention provides a sheet supplying and conveying apparatus comprising a sheet supporting means for supporting sheets, a convey roller contacted with the sheet supported by the sheet supporting means with predetermined sheet supplying pressure and adapted to feed out the sheet and convey the sheet around the convey roller by rotation of the convey roller, a separation rotary member urged against the convey roller with predetermined separation pressure and adapted to separate the sheets fed out by the convey roller one by one, a torque limiter for permitting rotation of the separation rotary member in a sheet conveying direction when rotational torque directing toward the sheet conveying direction and having a value greater than a predetermined value acts on the separation rotary member and for preventing the rotation of the separation rotary member in the sheet conveying direction when the rotational torque having a value smaller than the predetermined value acts on the separation rotary member, and a pressure releasing means for releasing the sheet supplying pressure and the separation pressure on the way of the conveyance of the sheet by the convey roller. The present invention further provides a recording apparatus having such a sheet supplying and conveying apparatus.
