Claims

[Scope of utility model registration request]

A thickness gauge that detects the thickness of a rigid steel plate being rolled by a rolling mill; 1. A comparator that divides the plate thickness deviation from the thickness gauge into off-gauge and on-gauge, a pulse generator that generates a clock pulse corresponding to the winding speed of the steel plate coming out of the rolling mill, and an off-gauge signal of the comparator porridge. a first pulse counter that is set by the on-gauge signal from the comparator, counts the clock pulses up to a set value, and outputs the count value; and a first pulse counter that counts the clock pulses from the start of rolling; a second pulse counter that stops counting operation and outputs the count value when an output signal of the count value corresponding to the on-gauge area is output from the first pulse counter; and a count value corresponding to the on-gauge area from the first pulse counter. An apparatus for measuring an off-gauge length during rolling of a steel plate, comprising: an output signal from the second pulse counter as an interrupt input signal;
