ABSTRACT:
A printer comprises a first paper feed passage extending from the rear of a platen to a printing position through the lower part of the platen, and a second paper feed passage extending from substantially just under the printing position to the printing position. A first pinch roller is disposed on the way to the first paper feed passage for pressing a first paper against the platen. The first paper is fed by rotating the platen. A second pinch roller is disposed on the way to the second paper feed passage for pressing the second paper against the platen. Rotation of the platen here causes the second paper to be fed. In addition, a paper insertion device according to the present invention includes a flat part for placing a paper thereon and a slit for converting the advance direction of a paper from horizontal to vertical. With the second paper placed on the flat part and inserted into the printer, the paper is directed upward after the curved surface of the slit and allowed to enter the second paper feed passage with ease for further advance.
