とを特徴とするプリンターのセンサー機構。 In a sensor mechanism of a printer that detects a position by intermittently receiving light emitted by a light emitting part through a transparent part of a sensor slit and a sub-slit at a light receiving part, a gap between the sensor slit and the sub-slit is maintained constant. 1. A sensor mechanism for a printer, characterized in that a roller is provided for the sensor slit, and a diameter of a portion of the roller that faces the light-transmitting portion of the sensor slit is reduced.
