THERMAL HEAD FOR THERMAL RECORDING

摘要

PURPOSE:To perform a high density recording at a high speed by providing a protective cover having a projected part approaching a semiconductor element for driving heat generating bodies and a conductive heat transmission means between the projected part of the protective cover and the semiconductor for driving heat generating bodies. CONSTITUTION:A recording paper 9 is pressed on a thermal head 11 for thermal recording with a paper feed roller 10 and according to a picture signal, a heat generating body 13a is driven with a semiconductor element 15 for driving heat generating bodies and the recording paper 9 is fed in the direction of the arrow to perform a recording generating heat. A projected part 16b is provided at the point corresponding to a recessed relief part 16a of a protective cover 16 on the semiconductor element 15 for driving heat generating bodies while a heat transmission member 17b is provided between the projected part 16b of the protective cover 16 and the semiconductor element 15 for driving heat generating bodies. Thus, the protective cover 16 can be utilized as a radiating plate of the semiconductor elements 15 for driving heat generating bodies to reduce the temperature rise of the element 15.
