Abstract

PURPOSE: To improve the probability of detecting superposed feeding and improve reliability by providing a stadard balue setting register and a compared data register and judging superposed feeding of the blank sheets through comparison of the both data.
CONSTITUTION: In the detecting apparatus equipped with a light source 101, photosensor 102, amplifier 103, and an A/D converter 104, the control part 105, upper and lower limit standard value setting registers 105 and 106, and a compared data register 108 are installed. The prescribed coefficient smaller than 1 is multiplied by the value obtained on a standard blank sheet, and the resultant value is set as the upper limit standard value in the register 106, and the prescribed coefficient larger than 1 is multiplied by the value obtained on the standard blank sheet, and the resultant value is set as the lower limit standard value in the register 107. Afterwards, the control part 105 inputs the data corresponding to the amount of light transmittance into the register 108 every time when the blank sheet C is sent-out from a hopper H, and judges whether the value is within ghe range of the registers 106 and 107 and detects superposition of two sheets.
