Abstract

PURPOSE:To eliminate the gain regulation of the voltage amplifier associated with changes in the nozzle replacement, ink beam position adjustment and charging efficiency by controlling the gain of the voltage amplifier so that the output of the voltage amplifier at the optimum phase is invariably held within the prescribed voltage. CONSTITUTION:The signals F and F/n from the phase shift circuit 13 and the single DIN from the converter D are inputted into the gain regulation circuit 50. When the gain of the voltage amplifier 24 is too small, under the phase condition of n, the output vo of the smoothing circuit 25 changes to L from VF2 while the output of the latch 66 goes to L. After the end of the n phase checking, the signal of F/n is inputted to the up/down counter 65 for down counting. When the counter is H (high level), the switches 61-64 are closed. The down counting increases the total value of the feed back resistances 71-74 resulting in an increase in the gain of the amplifier 24. At the same time, the entry of the signal F/n clears the latch 66.
