を特徴とする媒体厚検知機構。 When a print medium is inserted between a fixed first roller and a movable second roller, a sensor moves integrally with the second roller that moves in a direction perpendicular to the print medium. A medium thickness detection mechanism of a printing device that detects the thickness of the printing medium by a support member that integrally supports the second roller and the sensor, and a support member that integrally supports the second roller and the sensor; an elastic member for pressing against the roller; one end rotatably supported by the support member;
a link member whose other end is biased by the elastic member; a fixed shaft that rotatably supports the link member between the one end and the other end; and a fixed shaft that guides the support member in the vertical direction. A medium thickness detection mechanism characterized by having a means for detecting a medium thickness.
