Abstract

PURPOSE:To improve recorded image quality by providing a thermal resistor shaped a parallelogram or rhombic and arranging adjoining thermal resistors in such a way that their angles may look overlapped as viewed sideways. CONSTITUTION:Plural thermal resistors 1a of parallelogram are aligned in almost straight line, and the angles of adjoining thermal resistors are set so that they may look overlapped as viewed from side. Then color-forming dots 2a develop an overlapped part A on part of each upper and lower section when process sequence such as heat sensing and thermal transfer recording is performed. However, no gap 4 does not generate, thus insuring satisfactory recorded image quality. '3' represents a lead wire, and the thermal resistor 1a may be of rhombic form.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は、感熱、熱転写記録装置のサーマルヘッドに関
