Abstract
PURPOSE: To get rid of unnecessary tray by improving the sweep circuit in a way to set down the pen upon starting sweeping and set up the pen immediately at the end of sweeping.
CONSTITUTION: In time sweeping mode, when SW3 is connected to a contact 2, an integrator IG starts to integrate stable voltage ES2, and the output voltage is applied to a servo-circuit XS through contact 2 of SW1 to start time sweeping. On the other hand, transistor Q2 of a pen up-down drive circuit PUD becomes ON, Q3 becomes OFF, and Q4 is ON, so that a solenoid SN is excited, causing the pen to move down. The pen moves at a speified speed along X-axis by the sweep voltage of integrator IG. When the pen arm reaches the end point of effective recording range, the motor is stopped by the stopper. Accordingly, the differential signal of a differential amplifier A2 is increased on the negative side, and a light emitting diode DP is illuminated, and photo transistor QP is set ON. This causes the base potential of Q2 of pen drive circuit PUD to be earth potential, and Q2 is put OFF, Q3 is turned ON, and Q4 becomes OFF, so that the solenoid SN is not driven, thereby causing the pen to move up.
