Abstract
PURPOSE: To obtain an automatic correction circuit containing a special portion for controlling a motor used to overrun a sliding mount to make it possible to obtain a record output in proportion to the line density on a plate.
CONSTITUTION: A portion 2 for controlling a motor used to overrun a sliding mount can make the line density on a printing plate continuously variable by adjusting an input voltage for driving the motor, controlling the speed for overrunning the sliding mount and changing the input voltage. A voltage conversion circuit 1 is the one which changes the voltage inputted to the portion 2 for controlling the motor used to overrun a sliding mount, and this conversion output is used to input power to a carrier oscillation circuit 3. The carrier oscillation circuit 3 generates a high frquency output to transmit a picture signal input. A modulator 4 modulates the carrier high frequency output by means of the differential output between a picture signal input and the voltage value of a texture justifying input. A power amplifying portion 6 amplifies the modulated output in terms of power, while a voltage amplifying portion 7 amplifies the power amplifying portion 6 in terms of power. The record output derived from the voltage amplifying portion 7 depends on the power source voltage from the carrier oscillation circuit 3.
