SCANNING APPARATUS FOR HAVING A CCD TRIGGER PULSE GENERATOR WITH A POSITION TRIGGER

摘要

PURPOSE: A scanning unit with an image location synchronization device of an image sensor trigger signal generator is provided to scan an image of a high resolution by synchronizing a trigger signal with a starting point of an available image. CONSTITUTION: A CPU(100) controls all operations of a scanning unit, sets up a period value and a coefficient value of a trigger signal, and an interrupt service. A trigger signal generator(200) receives the period value and generates a trigger signal. An over-shoot controller(300) generates a flag signal for obtaining a desired value of input minimum values. A synchronization signal generator(400) outputs a command for generating the trigger signal of a normal period to the trigger signal generator.
