<P>PROBLEM TO BE SOLVED: To stop a disk at a prescribed position by detecting a change in an output signal from a detector which should fundamentally detect the change even if the output signal is overlapped with an unintended signal from the detector when a motor is rotated in a system using the motor, in particular a system in which the motor rotates the disk on which multiple reagents or specimens are installed. <P>SOLUTION: A motor system removes an abnormal signal and determines whether a change in a signal is adequate or not by means of a filter circuit capable of changing a characteristic depending on the rotation state of a disk in an input circuit of a motor controller relative to an output signal from a detector when the disk is rotated and a monitoring circuit for monitoring a signal state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
