PURPOSE:To cause static electricity on a recording paper to escape and prevent breakage of a thermal head and jamming of the recording paper, by covering the outer peripheral surface of a platen with a conductive elastic material. CONSTITUTION:A platen 2 comprises a core member 2a formed of a metal and a conductive elastic material 2b such as a conductive rubber covering the cylindrical outer peripheral surface of the core member 2a. Since the elastic material 2b consists of a conductive material such as a conductive silicon rubber prepared by uniformly dispersing carbon black or a powder of a metal such as silver and copper in a silicone rubber, static electricity on a recording paper 4 is not accumulated but is permitted to escape to the elastic material 2b of the platen 2 against which the recording paper 4 is pressed, and the static electricity can be made to escape through the metallic core member 2a, a shaft 2c and an earthing member 6 to a casing 7 of a recorder. Accordingly, jamming of the recording paper 4 can be prevented from occurring due to electrostatic adhesion. |
