ABSTRACT:
A paper feeder for a printer in which a paper separator roller 15 is rotatably provided in the end portion of a paper holder 12 so that when a paper feed roller 14 is rotated in the paper feed direction, the paper separator roller 15 is arranged to stop at a predetermined position and act similarly to a conventional friction pad, while when the paper feed roller 14 is rotated in the paper return direction, the paper separator roller 15 also rotates in synchronization with the above rotation. By way of vibrating the paper separator roller 15 in the rotational direction or another direction, paper sheets P stacked on the paper holder 12 are vibrated for the purpose of being successively moved in the portion at which the two rollers 14 and 15 are positioned in contact with each other. As a result of this structure, the paper feeder of the printer according to the present invention can be prevented from local abrasion of the paper separator roller 15 causing papers to be fed in an overlap manner, and stop of paper feed can be prevented, and papers can be assuredly fed one at a time to the printing mechanism portion 1.
