Abstract
A thermoelectric printer includes a cartridge accommodating a pair of reels around which a thermoelectric ink ribbon is wound, a carriage for removably supporting the cartridge, a printing head disposed on the carriage to apply a recording voltage to the ink ribbon to carry out printing, and a return electrode disposed inside the cartridge to electrically contact the ink ribbon. A resilient member conductive to the return electrode is also arranged inside the cartridge. The carriage has a contact element. When the cartridge is installed to the carriage, the contact element protrudes inside the cartridge to forcibly-contact the resilient member to form an electric correction between them. Then, a printing current flows from a recording electrode of the printing head to the ink ribbon, return electrode, resilient member and contact element and is then discharged to the carriage.
