Abstract
A paper feeding device for automatic drafting machine in which paper is fed in a predetermined direction by drive rollers and pressure rollers that are in resilient contact with the drive rollers. A writing implement is shiftably disposed in a right angle direction to the feeding direction of the paper, and the writing implement abuts on the paper. A predetermined pattern is drawn on the paper by mutual operations of the transfer of the writing implement and the transfer of the paper in the feeding direction. Underlay rollers are disposed in parallel to the transfer path immediately below the transfer path of the writing implement. The direction of drive and rotation of the underlay rollers is identical with that of the drive rollers, and a circumferential speed of the surfaces of the underlay rollers is set slightly higher than a circumferential speed of the drive rollers.
