Abstract

PURPOSE:To surely prevent a feed of plural sheets at a time, in a paper feeder of copying machines, by providing means for inhibiting rotation of a separator roller when a form is held between a conveying roller of the form and its driven separator roller. CONSTITUTION:At paper feed operation, firstly a feed roller 13 begins rotating to feed the uppermost paper of piled papers 11, at this time, a separator roller 15 is not applied with a brake, driven and rotated by a conveying roller 14, then a form is surely held. Secondly if the fed uppermost paper is held between the feed roller 14 and the separator roller 15, a solenoid 17, constituting a brake device, is electrically conducted to pull a brake belt 18 and stop rotary motion of the separator roller 15. Accordingly, when at least two sheets of forms are fed out, only the upper paper is conveyed, and only one sheet can be surely conveyed. And then, the conveying roller 14 continues rotating to convey the form to resist rollers 16.
