Abstract (en)
[origin: EP0072494A2] A thermal head which comprises a plurality of heating resistor strips (14, 16) arranged in a main scanning direction on an insulator layer (10). Each heating resistor strip (14, 16) includes a plurality of resistor pieces (261, 262, ..., 281, 282, ...) aligned in a main scanning direction. The resistor piece (261, 262, ..., 281, 282, ...) of each heating resistor strip (14, 16) is displaced in a main scanning direction so as not to be superposed in the subscanning direction. The resistor pieces (261, 262, ..., 281, 232, ...) of each heating resistor strip (14, 16) are supplied with currents in response to bit data at a predetermined timing and are thus heated to obtain a line of recording dots for a main scanning line.
