PURPOSE:To decrease the number of drive sources to make it possible to simplify the mechanism of a paper feed system in a recording device, by retracting a paper feed roller from its operating position by the drive force of a drive source for feeding a recording paper, before recording. CONSTITUTION:When a motor M2 is driven to rotate the rubber section 120a of a paper feed roller 120 the topmost recording paper alone is fed out, and a timer is simultaneously set. If the recording paper does not pass a paper sensor 101 just before a platen 101 within a predetermined time, the rotation of the motor m2 is stopped while a motor M1 is rotated in the direction D by a predetermined number of pulses, and therefore, the paper feed roller 120 and a paper discharge roller 124 are retracted by means of a gear 10, a friction clutch 115 and a sector gear 118 to carry out the disposal of paper jamming. If no jamming occures when the paper 101 is bit into between the platen 101 and a registering roller 103, the motor M1 is stopped, and then is rotated in the direction D by a predetermined number of pulses to be held at a printing position. |
