IPC: G03G15/01
Filed: 2007-08-16
Abstract: <P>PROBLEM TO BE SOLVED: To ensure the detection accuracy of a mark formed on an carrier.  <P>SOLUTION: The greater a difference between a quantity of light reflected from the surface of a conveying belt 18 and a quantity of light reflected from a mark, the greater an amount of adjustment is made to increase a difference between the output level of a light receiving signal corresponding to the light reflected from the surface of the conveying belt 18 and a threshold value. Thus, if the difference between both the quantities of light is large, the effect of noise components in an output level corresponding to the light reflected from the surface of the conveying belt 18 can be suppressed during the mark detection. Thereby detection accuracy can be improved. If the difference between both the quantities of light is small, the difference between the output level corresponding to light reflected from the mark and the threshold value can be maintained by restraining the amount of adjustment.  <P>COPYRIGHT: (C)2009,JPO&INPIT
