<p>PURPOSE: To maintain a sheet supply condition favorable even in the case where a reverse roller or feed roller is abraded. CONSTITUTION: In an FFR type sheet supply device provided with a feed roller 2 and a reverse roller 4, a press arm 24 to press the reverse roller 4 to the feed roller 2 is provided to be capable of oscillating freely, and a second torque limiter 22 to transmit a specified torque to produce this press force to the press arm 24 is provided. The specified torque is transmitted to the press arm 24 from the second torque limiter 22, and the press force by the press arm 24 is set to be almost constant even in the case where the feed roller 2 or reverse roller 4 is abraded, thereby feed failure of sheets or happening of double feed due to abrasion of the reverse roller 4, etc., can be prevented.</p> |
