ABSTRACT:
A serial printer comprises a carriage (21) which is movable parallel to a platen roller (11) and on which are mounted a character carrying disc (28) having a flexible blades, a stepping motor (26) for selecting the character to be printed, and a striker hammer (30, 31). The carriage is slidable on a cylindrical guide (17) and is provided with a pair of slider members (62, 63) which co-operate with a fixed bar (18) that is parallel to the guide (17) and to the platen roller (11). Mounted on the fixed bar (18) at the left-hand side of the printer is a key (70) which can co-operate with the slider members (62, 63) of the carriage to disconnect them from the bar (18) and to permit the carriage (21) to be swung down so that the character carrying disc (28) can be easily removed and replaced.
