COLOR REGISTRATION SENSOR FOR A IMAGING DEVICE, CAPABLE OF DETECTING A REGISTRATION TEST PATTERN REGARDLESS OF AN INSTALLATION POSITION OF A COLOR REGISTRATION SENSOR AND THE EFFECT ON AN ANGLE OF A LENS THAT IS REQUIRED FOR LIGHT EMITTING AND RECEIVING, A METHOD OF DETECTING A REGISTRATION TEST PATTERN BY USING SAME, AND A IMAGING DEVICE THEREOF

摘要

PURPOSE: A color registration sensor for an imaging device, a method of detecting a registration test pattern by using the same, and an imaging device thereof are provided to effectively detect a registration test pattern at a low cost by using a color registration sensor which is equipped with an electrode.;CONSTITUTION: A first electrode (110) detects a current which is generated by the electric force of an electrified toner that forms registration test patterns as registration test patterns for multiple colors which are formed on a transfer medium of an imaging device approach a color registration sensor (100). A first voltage generation unit (120) generates a first voltage signal corresponding to a first voltage signal by converting the current. A signal processing unit (130) detects a registration test position of each color by using the first voltage signal.;COPYRIGHT KIPO 2013;[Reference numerals] (110) First electrode; (120) First voltage generation unit; (130) Signal processing unit
