Platen roller, and recording device, thermal activation device, and sticking label printer provided with the platen roller

摘要

There are disclosed a platen roller capable of inhibiting at least one of drop of an adhesive force of a thermally active adhesive layer and deterioration of the platen roller which are seen in a case where recording and thermal activating are performed with respect to a thermally active adhesive sheet having the thermally active adhesive layer on a backside of a recording surface of a sheet-like substrate, and a recording device, a thermal activation device, and a sticking label printer which are provided with the platen roller. As a platen roller for conveying the thermally active adhesive sheet having the thermally active adhesive layer on the backside of the recording surface of the sheet-like substrate, a platen roller is used whose roller portion contains a fluorine atom containing rubber.
