  • Printer with reciprocating printhead carriage
    Patent number: 7568852
    Abstract: A printer including: a frame, a bearing assembly mounted to said frame, a platen rotatably supported in the bearing assembly for advancing a sheet of a recording medium, a guide rail mounted to the frame and extending in parallel with an axial direction (Y) of the platen, a ruler extending in parallel with the guide rail, a carriage driven to reciprocate along the guide rail and carrying a printhead, and a detector arranged to detect the position of the carriage relative to the ruler, wherein, in said axial direction (Y), the ruler is rigidly fixed at a location of the bearing assembly independently of the guide rail.

  • Frame structure for a scanning-type printer
    Patent number: 7401991
    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 gui
