In a spacing mechanism for a printer, the spacing mechanism includes a belt that is stretched in tension and has a plurality of teeth formed on its inner circumferential surface that mesh with the teeth of the pulley and the teeth of the idle roller. The tooth profile curve and the tooth profile curve of the root surface adjacent to the root surface are formed in a continuous substantially U-shape, and the tooth profile curve of the tooth root surface is continuous with the tooth profile curve of the root surface. The belt is formed into a generally arcuate shape that is swollen outward, and the tooth profile curve of the idle roller is formed in the same shape as the tooth profile curve of the pulley, and the tooth profile curve of the belt is such that the belt can When the belt is stretched by a roller, the tooth tip surface of the belt is formed in a shape that matches the tooth bottom surface of the pulley, and the tooth tip surface of the belt matches the tooth root surface of the pulley. 1. A spacing mechanism for a printer, characterized in that the belt is formed in a shape such that a tooth root surface of the belt is formed in a shape that matches a tooth end surface of the pulley.
