It consists of an elastic roller made of sponge or the like, and a harder roller than the elastic roller, which is pressed into contact with the elastic roller so as to bite into the elastic roller by 1 to 2 mm. The roller is a grooved roller having a plurality of grooves at the same intervals, a guide plate for manually feeding paper is disposed through the groove, and a manual feed stop sensor is provided in the groove near the exit of the roller to stop the feed roller. What is claimed is: 1. A manual feeding device, characterized in that the leading edge of the sheet is placed in a standby state near the exit of the roller, and curling is performed only on the leading edge, depending on the sensor and the operation timing of the manual feeding device. (2) A hard roller is on the driving side, an elastic roller on the driven side is rotatably supported on an eccentric shaft connected to the driving roller shaft of the hard roller via a counter-rotating clutch, and the amount of eccentricity of the eccentric shaft is controlled. Claim: 1. The amount of penetration of the hard roller into the elastic roller is approximately 2/1, and the penetration state between both rollers is formed only with respect to the leading edge of the paper by rotational displacement of the eccentric shaft. (1) Manual feed device as described.
