Title: Thermal head
Inventor: MICHIHIRO TOSHIAKI
IPC: B41J2/335
Filed: 1991-11-29
Abstract: PURPOSE:To provide a thermal head which can form accurately a required print image even on a recording member consisting of a hard material which is hardly curved. CONSTITUTION:A plurality of heating resistors 2 are mounted on one main face 1a of an electrical insulating base sheet 1 and a driving IC 5 for performing selectively joule heat generation of the heating resistor 2 is mounted on another main face 1b. The surface of the side of the electrical insulating base sheet 1 on which the heating resistor 2 is mounted becomes approximately flat thereby and as the result, it is unnecessary to curve a recording member 6 when the recording member 6 is fed on the heating resistor 2 to form a print image and it is possible to form a good print image as it is even when the recording member 6 consists of a hard material such as a plastic.
