Abstract

PURPOSE:To smoothly convey copying paper, in a device where the copying paper is lifted, pressed to a feed roller, taken out sheet by sheet and fed by resist rollers, by releasing paper feed pressure when the resist rollers are rotated. CONSTITUTION:A paper feed roller 8 is rotated clockwise, then the uppermost copying paper 7' on a feed paper cassette 1 is fed. Then if a point end of the copying paper 7', before reaching resist rollers 12, is detected by a paper sensor 13, the paper feed roller 8 is stopped rotating after several pulses. Then immediately the resist rollers 12 are rotated in a direction of arrow marks, and the copying paper 7' is conveyed forward. Further at this time, simultaneously with rotation of the resist rollers 12, a solenoid 9 is turned on to rotate a pressure lever 2 clockwise and separate a pressure roll 5 from a bottom plate 6 of the feed paper cassette. Accordingly, press contacted pressure of the copying paper 7' to the paper feed roller 8 can be reduced to smoothly convey the copying paper 7'.
