PURPOSE:To provide a fast recordable thermal head with simplification of various wirings by arranging a signal wire, a clock wire and power supply wires of logic circuits between a gate wire and a grounding wire which are formed at a specified position to be connected to several heating elements. CONSTITUTION:Several gate wires 4 are formed at the position the farthest from a plurality of heating elements 1 aligned and a grounding wire 8 at the position the closest thereto respectively parallel with the heating element 1. At least signals 5 and 5', two clock wires 6 and 6' and a power supply wire 7 of logic circuits are arranged in an area between the gate wires 4 and the grounding wire 8. The first of the gate wires 4 is arranged at the position the closest to the heating elements 1 in such a length that it can be connected to a gate terminal of silicone chips 3 No. to No.M. The signal wire 5 is connected to a signal input terminal D.IN of silicon chips 3 No.1, No.M+1.... |
