Abstract

PURPOSE:To eliminate the effect of external magnetic induction noises and improve S/N, by coaxially and closely attaching a noise-cancelling printed-wiring board having the same wiring configuration as a printed wiring for tachogenerator to the back surface of a generator wiring board, and connecting both the printed wirings. CONSTITUTION:To the back surface of a printed wiring board 7b for a tachogenerator, a printed-wiring board 7a is closely attached having a wiring configuration which is the same as that of the wiring for the generator for noise cancelling purpose or whose inner area surrounding the wiring is approximately equal to that of said printed wiring board 7b as well as whose wiring has an impedance approximately equal to that of said wiring for the generator, the generator wiring 14b and the noise component-canceling wiring 14a being connected together through a tangent wiring 15. In addition, the terminal 16a of the wiring board 7a and the terminal 16b of the wiring board 7b are arranged so that the external noise component is the same phase while the tachogeneration signal is the opposite phase with respect to the connecting wiring 15. Thereby, the noises are cancelled, the signal is intensified, and S/N can be largely improved.
