摘要： The light emitted from a paper detection sensor is reflected on a ribbon guide in the absence of a printing paper. The reflection light is received by the paper detection sensor to eliminate erroneous recognition of paper detection.
[Means for Resolution]
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 a slant surface (3b,3d), inclined relative to a surface of a printing paper (P) to reflect the light emitted from the paper detection sensor (4) toward a position outside the paper detection sensor.
