MEDIUM-PRINTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To switch printing colors in a simple structure by a movement of a printing head part. SOLUTION: A ribbon-switching assembly 4 set to a printing head part 1 has a slide bar 17 which moves along a movement direction of the printing head part 1. The printing head part 1 moves, thereby moving a projecting part of the slide bar 17 while butting the projecting part with a right upper frame 8a or a left upper frame 8b. An ink ribbon is accordingly moved in a breadthwise direction to switch printing colors.
