Abstract: A fault inspection system for the rotary machine is disclosed in which the rotational speed or a physical quantity related thereto of the rotary machine drive with changing rotational speeds is detected as a first detection signal, and the sound pressure or mechanical vibration from the rotary machine as a second signal. A reference line representing the relationship between the values of the first and second detection signals is determined on the basis of the same values. A fault of the rotary machine is detected on the basis of a third detection signal associated with an area corresponding to the region where the first or second detection signal exceeds the reference line.

During driving scanning of the light emitting elements and the light receiving elements in the direction of the X-axis, a light reception signal developed in response to incident disturbant light from a selected one of the light receiving elements in the direction of the Y-axis is stored into a memory, and then the light reception signal is subsequently read out from the memory and is subtracted on a subtractor from a light reception signal developed from a light receiving element selected upon driving scanning for the direction of the Y-axis. The subtractor thus provides a position signal from which an influence of disturbant light has been eliminated assuredly.
