ABSTRACT:
When an operator manually rotates flanges for holding roll paper, flange placement rollers rotate accordingly. Paper is supplied from the roll paper, and rotational force of one of the flange placement rollers is transmitted to a drive roller by a gear mechanism. Once the tip portion of the paper is held between the drive roller and an idler roller, the paper is semi-automatically fed to a set position by rotation of the drive roller. A torque limiter is provided in the gear mechanism to prevent an undesirably large load from being exerted on the paper.
