PURPOSE:To enable data immediately after printing to be confirmed soon by positioning heating resistors to as much near the end of an insulating base plate as possible. CONSTITUTION:A vitreous thermal insulator graze layer 8 is formed on the surface of an insulator base plate, and an array of many heating resistors 9 in a row is formed on the layer 8. The resistors 9 on the graze layer 8 are connected with separate cells 10 for power supply and a common cell 11, facing each other, where the cell 11 is extended to the tips of the cells 10 through the downside of the layer 8 and fetching is made from the cell 11 at the end portion. Since the fetching is made on the same side as the cells 10 in relation to the resistors 9, the width of the common cell 11 becomes smaller, and the position of the resistors 9 comes near the end of the insulator base plate. |
