Gap-adjusting mechanism

Abstract

Abstract PURPOSE:To provide a small-type lightweight gap-adjusting mechanism for a platen while retaining printing performance, by engaging through an eccentric bush a carriage with a guide shaft fixed between frames. CONSTITUTION:In a serial printer for printing on a paper by a printing head 21 mounted on a carriage 22 moved in the direction of an arrow 30 along guide shafts 23, 24 (numeral 25 denotes a platen), (i) the guide shafts 23, 24 are placed by fixing both ends thereof to the frames 28, 29, and (ii) the carraige 22 is engaged with the shaft 23 through the eccentric bush 26 rotatably fitted into an engaging part and is engaged with the shaft 24 through a hole 27 formed in an oval shape. Accordingly, by rotating the bush 26, the carriage 22 is moved in the direction of an arrow 31, and the gap between the printing head 21 and the platen 25 can be freely adjusted.
