ABSTRACT:
The paper strip conveying apparatus includes a conveying roller which is provided in such a manner that the outer peripheral plane comes into contact with one surface of a paper strip, a roller drive mechanism which rotates the conveying roller and a paper strip biasing member which is provided in such a manner that the tip portion comes into contact with the other surface of the paper strip. A convex portion is formed circularly along the outer peripheral plane of the conveying roller. The paper strip biasing member has a concave portion into which the convex portion of the conveying roller fits without contact at the tip portion. When the paper strip is sandwiched between the conveying roller and the paper strip biasing member, since the convex portion of the conveying roller fits into the concave portion of the paper strip biasing member, the paper strip is forcedly flexed so as to be urged onto the convex portion of the conveying roller and conveyed by the rotation of the conveying roller. In the other cases, since the conveying roller and the paper strip biasing member do not come into contact with each other, the conveying roller does not receive any external force, which results in reduction of rotation load of the conveying roller.
