Abstract
A printer with excellent anti-static protection removes static electricity from the paper guide and recording paper and protects a paper detector from static. A printer 1 has a plastic frame 19 disposed facing the paper path A, and a stainless steel anti-static guard member 20 attached to the plastic frame 19 on one edge in the paper width direction X. The anti-static guard member 20 includes a protective plate 21 that shields the area around the detection unit 18a of a paper detector 18 from the paper path A; a paper guide 22 protruding from a side edge of the protective plate 21 to the paper path A side; and a ground part 24 connected to the protective plate 21 through a connecting part 23. The connecting part 23 and ground part 24 form a flat spring pressed against a case-side ground member 25.
