Title:
SYNCHRONIZING SIGNAL GENERATOR
Document Type and Number:
Japanese Patent JPH066534
Kind Code:
A
Abstract:
PURPOSE: To easily generate a synchronizing signal with high accuracy based on a deflecting state signal of an optical deflector.
CONSTITUTION: A phase of a deflection state signal obtained by a sensor coil 48 of a resonance optical deflector 22 is adjusted by 1st and 2nd phase adjustment circuits 66, 68 corresponding to a grid signal, and a blanking signal is obtained by a comparator 70. The synchronizing signal with high accuracy is generated from the grid signal by using the blanking signal.
