Claims

[Claim for Utility Model Registration] By winding up the wire by rotating the winding drum by the lifting motor, the hopper base connected to the wire is raised, and the printing paper inside the hopper base is transferred to the machine via the hopping roller. In the paper feeding device that feeds the paper into the main body, if the printing paper runs out in the hopper base or a paper feeding error occurs during feeding, printing control within the device is stopped and the message is displayed on the display of the device. A sheet feeding device characterized in that, when processing is performed, means is provided for driving an elevating motor to place the hopper base at the lowest position at the same time as the display processing.
