摘要： A dot printer not using any type, nor requiring any ink ribbon has an ink roller 1, a platen 2 having an outer surface coated with ink by contacting the ink roller 1, and a printing head 3 facing the platen 2 in an appropriately spaced apart relation thereto. The printing head 3 is a dot impact type printing head having a plurality of printing wires caused to project selectively to form letters, and a recording medium 6 is conveyed between the platen 2 and the printing head 3 to have printing made thereon by the printing head 3. A protective film 8 is employed between the printing head 3 and the recording medium 6.

摘要： The present invention is directed toward a printer having a ribbon guide capable of reflecting light emitted from a paper detection sensor away from the paper detection sensor in the absence of a printing paper. As a result, the possibility of erroneous recognition of paper detection is eliminated. There are provided a print head 1, a ribbon guide 3 attached to the print head, and a reflection-type paper detection sensor 4 arranged on a side of the platen in a manner opposed to a printing paper P passing between the platen and the ribbon guide 3 to emit light for detecting the printing paper. The ribbon guide 3 is formed with sloped surfaces 3b and 3d that are inclined relative to a surface of a printing paper P to reflect the light emitted from the paper detection sensor 4 toward a position away from the paper detection sensor.
