Title:
MEDIUM-PROCESSING DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/050775
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving processing accuracy by minimizing minute changes in the tension applied to the medium surface to be processed. As a means of solving said problem, this medium-processing device (P) is a medium-processing device for conveying and processing a sheet-shaped medium, wherein a medium-winding structure (4) is equipped with: a winding roller (111) for winding a processed medium (M) in a rolled shape; a first tension-imparting means (120) having a first tension bar (121) for contacting the medium (M) and imparting tension thereto between the winding roller (111) and a medium-conveying structure (30); a first outer-diameter detection means for detecting the outer-diameter dimensions of the medium (M) wound around the winding roller (111); and a first position-changing means for changing the relative position of the first tension bar (121) in relation to the winding roller (111). Furthermore, a control unit (70) controls the first position-changing means in a manner such that the relative position of the first tension bar (121) in relation to the winding roller (111) is a prescribed position, on the basis of the detected outer-diameter dimensions of the winding roller (111).
