Title: System for detecting temperature of printing head
Inventor: WAKAMURA SHOJI
IPC: B41J29/46
Filed: 1984-10-12
Abstract: PURPOSE:To detect temp. without using a thermal element, by integrating the weighting corresponding to the detection level signal of a power source voltage detection circuit over the output period of the above mentioned detection level signal during the printing operation of a printing head to detect the temp. of a printing head. CONSTITUTION:Detection level signals V1, V2, V3 are outputted according to the variation of power source voltage VH. This power source voltage VH is the power source voltage of the coil of a printing head 1 and varied by the number of pins (coils) excited according to printing data. That is, the detec tion levels V1-V3 of a power source voltage detection circuit 3 and the heat generation of the printing head 1 have interrelation. An incremental count pulse selector 12 outputs incremental pulses PU1-PU3, which correspond to the generation quantity of heat, corresponding to the detection levels V1-V3 and an incremental and decremental counter 13 integrates the incremental pulses PU, which correspond to the generation quantity of heat, corresponding to the detection levels V1-V3 during printing operation. By this method, the detec tion temp. of a temp. detection circuit TSC shows the heat generation state (temp.) of the printing head 1.
