Abstract

PURPOSE:To enable a manual fine adjustment of the rotation of a platen by providing a connecting means between a platen rotating shaft and a step motor as driving source to meet specific requirement. CONSTITUTION:In a paper feeder in which manual control members (knob)4 and 5 are directly connected to a rotating shaft 2 of a platen 3 while being connected to a step motor 13 through proper connecting means 15, 17, 18 and 20, the number Z of steps required for covering one cycle of the number N of division (the number of steps per rotation of a rotor) and the switching in the excited phase of a step motor 13, a deceleration ratio K of the rotating shaft 2 by the connecting means with respect to the step motor 13 and the diameter D of the platen 3 are set to meet the formula: L/M.1/piD=K.Z/N.
