Abstract

A thermal image forming apparatus includes a platen roller, a thermal head facing a lower circumferential surface of the platen roller to form a first printing location and facing an upper circumferential surface of the platen roller to form a second printing location, a conveying part to convey a recording medium such that the recording medium passes through the first and second printing locations, and a guide roller to prevent the recording medium from being bent near the first and second printing locations by supporting the recording medium between the platen roller and the conveying part.

Description

technical field [0001] The invention relates to a thermal imaging device, and in particular to a thermal imaging device capable of forming images on both sides of a recording medium. Background technique [0002] figure 1 is a schematic diagram of a conventional thermal imaging device capable of printing images on both sides of a recording medium. refer to figure 1 , the conventional thermal imaging device 10 includes: a thermal imaging head 11, the thermal imaging head 11 faces the recording medium P to apply heat to the recording medium; a pressing roller 15, the pressing roller 15 presses the recording medium P toward the thermal imaging head 11; And a transfer section 20 that transfers the recording medium P. As shown in FIG. In the thermal imaging head 11 , on the surface facing the recording medium P, a plurality of heating spots 13 are arranged along the width direction of the recording medium P. As shown in FIG. The peripheral surface of the pressing roller 15 is...
