Heat-sensitive recording system

Abstract

Abstract PURPOSE:To prevent a heat-sensitive recording head from accumulating heat without causing an image to be disappeared, by dividing driving circuits into several groups that are operated at prescribed time intervals, and turning ON and OFF a source for driving the groups in accordance with the temperature of the heat-sensitive recording head. CONSTITUTION:The group selection driving circuits 2 are connected every other to be divided into two groups 10, 11, and one group 10 is directly connected to the electric source 12, and the other group 11 is connected through a bimetal 13 to the electric source 12. The bimetal 13 is placed on or near the heat-sensitive recording head so that when the bimetal 13 reaches a prescribed temperature, it is turned OFF to stop the feeding to the group 11 from the electric source 12.
