Abstract

A resin roller and a rubber roller are supported on the same shaft. The resin roller has a smaller diameter and a smaller coefficient of surface friction than the rubber roller. Alignment of the leading end of the medium is performed by bringing only the resin roller into contact with the medium. As for conveyance after that, higher pressure is applied to the shaft toward a pinch roller to bring both of the resin roller 3 and the rubber roller into contact with the medium.

Description

technical field [0001] The present invention relates to a technique for conveying media along a conveying path. Background technique [0002] For a document form / paper printer using a bankbook, document form / slip, etc. as a medium to be printed, there is a need for a mechanism capable of preventing the medium from being skewedly inserted into a print head that performs printing and are printed skewed. As a conventional technique, Japanese Patent Application Publication Nos. 2888251 and 3349922 disclose a printer which is structured to include a polygonal roller 100; a stopper 111; a transport roller 107; and a pinch roller 106, as shown in the figure 1A, FIG. 1B and FIG. 1C, and also includes a mechanism, which aligns the front end of the medium 108 by means of a polygonal roller 100 and a stopper 111, and by means of a transfer roller 107 and a pinch roller 106 opposite to the transfer roller 107 , the continuous transmission medium 108 . [0003] Referring to Figures 1A...
