Abstract
PURPOSE: To provide a serial printer having constantly fixed printing positions in each of them, by a method wherein the carriage shift is conducted through the engagement between a rack gear and a carriage driving gear.
CONSTITUTION: A carriage driving gear 52 is fitted to the lower part of a carriage 3, the gear 52 being provided on its peripheral surface with cam teeth 52a extending over slightly less than two turns. The cam teeth 52 engage with prescribed teeth 8a- 1 of a rack 8 in an angular range from 0°W170° and engate with teeth 8a-2 in an angular range from 170°W360°, and the carriage 3 is shifted by one character by the rotation of the gear 52 in engagement with the teeth 8a. After completion of the printing of one line, the rack 8 for the shift is moved by a blank printing instruction, the engagement between the teeth 8a and gear 52 is released, and the carriage 3 is returned by the force of a spring pulling the carriage 3 toward the initial position of the latter.
