PURPOSE:To achieve a recording with an even density by fixing a cylindrical cam having an eccentric through hole on a round bar mounted under a thermal line head 3 with a clamping screw 11. CONSTITUTION:After moved on a round bar 8 to the center thereof, a cylindrical cam 10 is turned to push up the most bent section A of a thermal line head 3 and fixed in site with a clamping screw 11. At this point, a recording paper is inserted between a platen roller 2 and the thermal line head 3 to check the density of the recording. If the density is not even in the axial direction of the platen 2, the clamping screw 11 is loosened to turn or move the cylindrical cam 10. Then, the adjusting screw is tightened and the density is checked again for readustment. |
