PURPOSE:To lower the unit cost saving trouble for exchanging tubules by employing a plastic disposable exchange type having an ink storage section for the tubule cartridge unit in a dot printer designed to stick out a cartridge. CONSTITUTION:A tubule cartridge 13 having an ink container 13C is energized with a spring 18 through guides 15, 16 and 17 fitted into a plastic frame 14. With the excitation of a plunger 19 by a solenoid, a tubule 13B sticks out to print on a printing paper 11. A tubule unit 12 is locked at a shaft 12 pressed with a press section 24A of a carriage 20. The press locked sections 12A and 24A is released by pressing a detaching lever finger press section 24B with a finger and allowed to be removed. The ink container 13C requires no more capacity beyond the damage to the tip of the tubule 13A and thus, the use of a plastic unit 12 can result in a lower cost. |
