求項１記載のシリアルプリンタ。[Claims for Utility Model Registration] (1) A serial printer that prints by bringing a print head into close contact with the platen while moving the carriage in the main scanning direction parallel to the platen, wherein the carriage is rotatable and a guide shaft slidably supported in the main scanning direction; a guide rail having a step on a guide surface between an intermediate portion corresponding to the printing range in the main scanning direction and an end portion outside the intermediate portion; and the guide rail. The printing head moves in the main scanning direction integrally with the carriage while being guided by the guide surface of the guide rail, and when it is in contact with the guide surface of the intermediate portion of the guide rail, the printing head is pressed against the platen, and the end of the guide rail is moved. A serial printer comprising: guide/follower means for separating the print head from the platen when in contact with a guide surface of the printer. (2) The guide follower means includes a roller means that rolls on the guide surface of the guide rail, and a roller means that rolls on the guide surface of the guide rail, and the roller means such that the roller means always contacts the guide surfaces of the intermediate portion and the end portion of the guide rail in parallel. 2. A serial printer according to claim 1, further comprising means for supporting said means. (3) The serial printer according to claim 1, further comprising means for maintaining the separation state of the print head from the platen even within the print range when moving in one direction in the main scanning direction.
