Abstract: PURPOSE: To reduce a low frequency electromagnetic field so as to suppress an organism influence, by providing an insulating layer between a center conductor and a heating unit, and short-circuiting the other end of this center conductor and the other end of the heating unit. CONSTITUTION: A commercial AC current supplied from a power source is made to flow in a heating unit 3 from a center conductor 7 via a short-circuiting part 9 through a power supply switch 5 and a power supply cable 4. In this way, the heating unit 3 generates heat. Here, in an alternating current flowing in the center conductor 7 and the heating unit 3, the magnitude of the current becomes equal with a flow direction reverse to each other, and also in a low frequency electromagnetic field respectively generated by these currents, similarly the direction becomes reverse to each other further with equal intensity. As a result, a low frequency electromagnetic field corresponding to a frequency of the supplied AC current and a generation almost low frequency electromagnetic field are reduced. The center conductor 7 is coated with an insulating layer 8, and it is coated with the heating unit 3.

Filed: 1978-08-22
Abstract: PURPOSE:To reduce the number of connecting terminals and increase printing speed, by supplying electricity selectively to heat generating bodies arranged in a line by means of movable electrodes and feeding paper for printing each line. CONSTITUTION:Drive plate 23 moves right and left, and in coordination with this movable electrode 22 sweeps fixed electrode 13. By means of control circuit, electricity is supplied only to those required fixed electrodes when they are connected to each movable electrode. One movable electrode 22 is assigned with a plurality of fixed electrodes 13. For example, assume that there are 20 places per line in a 5X7, one-dot space font. Then, the number of fixed electrodes is (5+1)X20=120. Suppose that there are five electrodes. Then, one movable electrode sweeps 24 movable electrodes. When printing of one line is completed, the movement of movable electrode 22 is reversed. But, before it starts sweeping in the opposite direction, rubber roller 26 rotates a fixed angle, and recording paper is fed by one dot. When sweeping is repeated for seven times in this way, printing of a one- line equivalent is done at the normal 5X7.
