Abstract

The printer comprises a carriage 23 moving in the direction perpendicular to the carrying direction of a medium, a print head 15 mounted on the carriage 23 and printing on the medium, and a ribbon guide 16 for guiding the ink ribbon to the forward end face of the print head 15. The ribbon guide 16 has a medium guide surface abutting against the medium and engages removably with the carriage 23 or the print head 15. Thus, the printer in which a ribbon guide can engage removably with a print head or a carriage mounting the print head and an ink ribbon can be replaced easily, surface of the ink ribbon abutting against a medium is prevented from abrading significantly to vary the interval between the upper surface of the medium and the print head, print quality is prevented from deteriorating, and winding of the ink ribbon is carried out with no trouble.

Description

technical field [0001] The present invention relates to printers. Background technique [0002] Conventionally, in financial institutions such as banks, post offices, and credit unions (financial cooperatives in Japan), printers such as voucher bookkeeping machines have been used to record accounts on vouchers such as deposit books (for example, refer to Patent Document 1).
