Abstract

PURPOSE:To obtain a manual printer which is convenient for service and with which printing can be easily performed on every possible places, by a method wherein a top end heating element array of a thermal head is established at an edge of a box body, and a part of a rear side end face in a transfer direction of the box body is notched so that the top end heating element array may be visually observed. CONSTITUTION:When printing is performed on a note or the like having a rule mark with a manual printer, as the start position of printing, a printer transfer direction is made coincident with a notched part 26f of a box body 26. Since besides an end face 26e of the box body 26 is notched and a thermal head 1 and an ink ribbon 17 can be visually observed from the arrow F direction, a center of the thermal head 1 is made coincident with a center of the rule mark of printing paper. A printing impossible area is an area wherein a distance B, a distance to a heating element array of the head 1 in total width E of the box body is subtracted from a difference in level part by left and right pages at a center of a note. Thereby, the printing start position can be visually observed, and can be easily judged from a changing part of the box body. Therefore, printing paper on which a printing possible area is determined becomes easily printable.
