Abstract

PURPOSE: The output from the detector with a light source and light-receiving element is passed through the logical circuit to control the size of damage to be judged to be defective arbitrarily.
CONSTITUTION: Detectors consisting of a light source and a light-receiving element is set on both upper and lower sides of the conveyor for laver sheets in parallel. The light-receiving elements are divided into two groups, one set around the periphery of the laver sheets A1WA5, A31WA36 and the other at the center part A7WA30 and each output therefrom passes through its arithmetic amplifier to the logical circuits composed of NAND gate B, NOT circuit C and NOR gate C. The output from the logical circuit is selected by the rotary switch RS and the detection signal is sent from the terminal 4. By switching the rotary switch, how many adjacent elements received light is detected, it means whether the laver sheet has damages or not, to judge whether the sheet is defective or not.
