Abstract
A thermal printer of the present invention is basically constructed to use roll form printing paper, but able to use also fan-fold form printing paper by mounting to a casing; a guide shaft for fan-fold form printing paper instead of a roll for roll form printing paper; and a guide unit for fan-fold form printing paper, provided with side plates for regulating both side edges of fan-fold printing paper and with a press plate for restricting the upper surface of the same, and mounted to the casing in condition of being connected to an opening between the casing and the rear end of a cover for the casing. The thermal printer of the present invention has a pair of reel plates to which the roll for roll form printing paper or the guide shaft for fan-fold form printing paper are mounted having larger diameter than the roll for roll form printing paper prior to use or guide shaft for fan-fold form printing paper, so that roll form or fan-fold form printing paper, when in use, is free from the skew, thereby enabling accurate and reliable paper feeding.
