Claims

[Scope of Claim for Utility Model Registration] In a printing device equipped with an automatic paper feeder, upon receiving a paper feed command, the feed roller of the automatic paper feeder is driven to rotate, and the printing paper is fed through a paper guide path to a platen. The first paper feeding mode sets the printing paper at the printing start position by rotating the machine, and the first paper feeding mode rotates the feed roller of the automatic paper feeding device in response to a paper feeding command to feed the printing paper through the paper guide path to the platen. Then, the platen is rotated to feed the printing paper to the outside of the automatic paper feeder, and the platen is further rotated in the opposite direction to introduce the printing paper into the paper evacuation path and set the printing paper at the printing start position. an automatic feed control device comprising: a mode switching means for selectively switching between paper feeding modes; and a paper feeding control means for driving and controlling the feed roller and platen based on the mode selected and set by the mode switching means. Printing device with paper feed device.
