とがあった。(Problems to be Solved by the Invention) However, the method used to measure the wire drawing amount and linear speed is to convert the voltage generated by a tachogenerator (alternating current generator) attached to a wire drawing machine into an analog/digital (A/D) The linear velocity was obtained by averaging the total voltage value per unit time taken in via a digital (digital) converter, and the length of the drawn strip was determined by integrating the linear velocity data over time. Therefore, it is accurate when the wire speed is constant, but when the wire speed changes greatly, errors occur in the wire feedout and accuracy cannot be obtained, and when the protector of the wire connection part passes the gold wheel, When repeating the unwinding and winding of the wire, an error may occur between the unwinding lines.

により主ローラ１は回転する。(Example) To describe an example of the present invention in detail, an electric wire C is held by a presser roller 2 and a main roller 1. The gripping force is obtained by a spring 4 attached to a presser roller arm 3 from the main body. The main roller 1 rotates due to the movement of the electric aC held by the presser roller 2 and the main roller 1.

１９２＋ｎまでの条長を測定することができる。The rotation of the main roller 1 is transmitted to the rotary encoder 6 by the timing belt 5, and the rotary encoder 6 is rotated. For the length, count the number of pulses on the rotary encoder 6 and set the number of pulses to 900 or 1800 by 1.
The data is output as a total of 12 bits of digital data. This 1 bit becomes 1m or 2m, and this digital bit is outputted as 12b1 (1v or IOV analog m) by D/A conversion.This allows a maximum of 8
