Abstract

An ink ribbon cassette (10) is provided with a shaft container (23) including a reel-out shaft holder (17) having a reel-out shaft bearing (13) journaling an ink ribbon reel-out shaft (12); a reel-in shaft holder (20) having a reel-in shaft bearing (15) journaling an ink ribbon reel-in shaft (14); and a pair of lateral bodies (16) connecting the reel-out shaft holder (17) to the reel-in shaft holder (20). A reel-out shaft holder cover (19) adapted to cover the reel-out shaft holder (17) of the shaft container (23) is connected to the reel-out shaft holder (17) via a first connecting body (18). A reel-in shaft holder cover (22) adapted to cover the reel-in shaft holder (20) of the shaft container (23) is connected to the reel-in shaft holder (20) via a second connecting body (21). The first and second connecting bodies (18) and (21) have two or more hinges (18a, 18b); and (21a, 21b), respectively.

Description

Technical field [0001] The present invention relates to a thermal transfer ink ribbon cartridge, and particularly relates to a miniaturized ink ribbon cartridge without a hinge part protruding to the outside. Background technique [0002] Generally, an ink ribbon cartridge with a thermal transfer ink ribbon is widely used in printing equipment such as printers. The thermal head of the printer contacts the ink ribbon, and thermally transfers the printed material on the ink ribbon. Printing ink ribbon dyes and pigments. Such a thermal transfer ink ribbon is supplied from the ink ribbon take-up shaft of the take-up bearing body of the ink ribbon cassette during printing, and is taken up by the ink ribbon take-up shaft of the take-up bearing body of the ink ribbon cassette. [0003] That is, as Picture 9 As shown, the conventional ink ribbon cartridge 30 is provided with: a winding bearing body 37 having a winding bearing 31 that axially supports the ink ribbon winding shaft 35 on w...
