ABSTRACT:
A printer including a frame, a feed roller rotatably supported in the frame for advancing a recording medium, a sheet support plate for supporting said recording medium, a guide rail extending in parallel with an axial direction (Y) of the feed roller, and a carriage guided at the guide rail and carrying a printhead facing the recording medium on the sheet support plate, the frame being composed of a support structure and two plate-like function blocks, which are supported on said support structure at both ends of the feed roller so as to extend in respective planes (X-Z) normal to said axial direction (Y), and which support the guide rail and the sheet support plate, wherein the feed roller is rotatably supported in two bearings, each of which has a bearing case, each bearing case being supported on a member of the support structure, each of the function blocks defining a downwardly open V-shaped notch which is supported on the peripheral surface of one of the bearing cases at exactly two points, and the guide rail rests on V-shaped top surfaces of the function blocks and is thereby accurately positioned in both directions (X, Z) normal to said axial direction (Y).
