Abstract
PURPOSE: To easily change a space between a printing head and a platen in accordance with in variations of the sheet number or thickness of paper and to provide clear print at all times by a printer wherein a plurality of printing surface facing the printing head with different gaps therebetween are provided on the periphery of the platen.
CONSTITUTION: A dial 12 is rotated to cause a platen 6 and a cam 13 to rotate and the platen 6 is fixed at a certain position with engagement between a recess 14 and a roller 15. When printing on a sheet of paper, for example, the softest printing surface 7 is positioned to face a printing head 5. At this time, the printing surface 7 has the largest diameter R1 and a gap S between the printing surface 7 and the printing head 5 becomes minimum in accordance with thickness of the paper. With the paper increasing in thickness thereof, a slightly soft printing surface 8, slightly hard printing surface 9 and the hardest printing surface 10 are used in due order. The respective printing surfaces 8W10 have radii R2WR4 decreasing gradually, so that the gap S is increased correspondingly. Thus, the uniform and clear print can be obtained irrespective of thickness of the paper.
