Abstract

PURPOSE: To constitute the instrument having no mechanical contact parts in the position feedback means of its movable part by providing a detecting means moving along a magnetostrictive wire in correspondence to the movement of the movable part which is driven by a balance motor.
CONSTITUTION: An amplifier AM inputted with the deviation ε of an input signal Ei and the feedback signal Ef from a position feedback means 6 drives a balance motor 44 according to the deviation ε. When the balance motor 44 is driven, a movalbe part 3 is moved along a guide rail 2 by way of a reeling yarn 41, by which a detecting part 61 is also moved and the position feedback signal Ef corresponding to the position of this detecting part 61 automatically balances in the position where it becomes equal to the input signal Ei. Hence, the movable part 3, i.e., recording pen 32, may be let to accurately follow up the input signal Ei, and from the recording positions thereof, the magnitude of the input signal may be known.
