PURPOSE:To facilitate assembling process and enhance the accuracy of positional relationships of a paper-feeding roller, a paper press roller and a paper-supplying guide, by a method wherein a bearing for a paper-feeding roller is fixed by pressing it against a partition wall of a paper-supplying guide by a platen, and a paper press roller is pressed against the paper-feeding roller to pinch a printing paper between them. CONSTITUTION:The bearing 54 for a roller shaft is provided with a projected part 55, a part of the partition wall 48 of a lower guide plate 46 is protruded on the upper side through an opening part of an upper guide plate 47, and the projected part 55 is fitted into a recessed part 56 of the wall 48 from above. The bearing 54 is pressed from above by a lower end surface of a platen 4, and the lower guide plate 46 is pressed from above by the bearing 54. The upper guide plate 47 is also pressed by the platen 4, and the platen 4 is pressed by a frame, thereby completing assemblage of the paper guide 7. The paper-feeding roller 52 and the bearing 54 are fitted and fixed to the partition wall 48 of the guide 7 by the platen 4, and the paper press roller 63 is pressed against the roller 52 to pinch the printing paper between them, so that the positional relationships of the rollers 52, 63 and the guide 7 are maintained to be constant. |
