Abstract

A platen-gap regulating apparatus for regulating a carriage (1) with respect to a platen of a printer, comprises: a pair of guide members (3,4) rotatably mounted on the printer via an eccentric portion (3a,4a), for running the carriage; and regulating means for imparting the same rotational displacement quantity to both the guide members, wherein the carriage (1) is separated from and drawn near to a printing reference plane (P) in parallel thereto.
