Title: Apparatus for preparing thermal head
Inventor: SAWAE TETSUNORI
IPC: H01L49/00
Filed: 1985-01-30
Abstract: PURPOSE:To easily grasp the reduction degree of the irregularity in a resistance value, by mounting a pulse generation circuit and a resistance meter while providing a calculation part to calculate the average value or standard deviation of the resistance value of a heat generating resistor. CONSTITUTION:A voltage pulse is applied to the heat generating resistor of a thermal head 7 from a pulse generation circuit 10 on the basis of the set signal of a peak value Vs and the number (n) of pulses by a calculation part 12. At this time, said voltage pulse is applied to the heat generating resistor, of which the resistance value is larger than an objective resistance R0, in one group of heat generating resistors. The preceding resistance value is compared with the lately resistance value and, when the lately resistance value is low and higher than the objective resistance value R0, the peak value Vs is made further high by DELTAV to adjust said lately resistance value to the objective resistance value R0 or less. When the adjustment of one group is finished by this method, CPU14 calculates an average value and standard deviation. When the adjustment with respect to all heat generating resistors of one thermal head 7 is finished, CPU14 calculates the average value and standard deviation sigmaof the whole and displays the result thereof on a printer 17.
