。 In a printer that uses roll paper, a disc with a slit is fixed to the rotation shaft of the roll paper, and the disc is rotated coaxially with the roll paper, and a sensor that detects the rotation speed of the disc is installed from the slit in the disc. A roll paper near-end detection device, which is installed on the side of a plate, detects the feed speed of the roll paper from the rotational speed of the disk, and displays a near-end display on a display unit when the roll paper reaches the near-end.
