Abstract
PURPOSE: To enable a stabilized measurement of little erroneous operation by performing a correction for temperature drop due to an iron oxide et al by a method wherein an output of a photoelectric element which was once generated is made to hold equivalently by means of a specified circuit.
CONSTITUTION: The 1st and 2nd photoelectric elements 15aW15n and 16aW16n are disposed in a detector 4 and according to the state of a figure, 15eW15k and 16dW 16m form an image of red heat steel 1. Here, if a pool 40 of iron oxide et al exists, the photoelectric elements 16g, 16h which should generate the output of red heat steel material 1 do not generate the output, thus, resulting in a detection error. Therefore, a shift register 42 is installed and the signals from the detector 4 which once generated output are held the output state through the register 42 and the data signals are sent to a substraction circuit 43. In the circuit 43, the difference of the plate width of steel sheets are operated from the parallel outputs of two photoelectric elements of the register 42 and the specified signals are output from a drive signal generating circuit 14, thus, an erroneous operation can be prevented.
