PURPOSE:To obtain the structure of arrangement of the captioned head well fitted for double- color recording by a method wherein two thermal heads with a plurality of heating elements arranged in a straight line in the end parts thereof are arranged and provided with roller for pressing the thremorecording paper and witha means for drawing out a supporting body from an aperture between the heads. CONSTITUTION:A thermorecording layer 2, an adjesive layer 3, an ink layer 4 and the supporting body 5 are laid sequentially on substrate paper 1, thus the thermorecording paper is obtained. When the 1st thermal head is made to touch the paper 1 and later the supporting body 5 is drawn apart, the adhesive layer 3 and the ink layer 4 in the unheated part are separated together with the supporting body 5, while, in the heated part, the supporting body 5 alone is separated. Then, the thermorecording layer 2 is made to contact with the 2nd thermal head and heated, thus double-color recording is attained. As a device for this purpose is employed a group of thermal head arrangements constituted in such a manner that two thermal heads 14 formed by arranging a plurality of heating elements 7 in a row in the end part on a substrate 10 and providing lead wires 6 and earth-wire electrodes 8 therefor are provided with an aperture between them, that a roller 13 pressing the recording paper 1 on both thermal heads 14 downward from the position above the heads is provided, and that rollers 13 and 13' drawing out the supporting body 5 from the aperture are provided. |
