Abstract

PURPOSE: To prevent a count error in case of a detection signal of a high speed, by dividing finely and roughly at the same time as to a length detection signal of an object to be measured, and counting in accordance with a speed of the detection signal.
CONSTITUTION: A length detection signal which is supplied is divided finely at 12 and roughly at 14 at the same time. A speed of the detection signal is detected 20 by use of the roughly divided output, and in accordance with this speed detection signal, in case when the speed of the detection signal is low, the finely divided output is selected at 18 and is output, and on the other hand, in case when the speed of the detection signal is high, the roughly divided output is selected at 18 and is output. And, each selected output is counted at 34, and length of an object to be measured is displayed digitally.
