Claims

[Claims for Utility Model Registration] A position that produces a signal that becomes a reference value at a predetermined stop position of a moving body driven by a motor, has different polarity before and after the stop position, and has a value that corresponds to the rotation angle of the rotary body. a detection means, a first comparator circuit having a first undesired band and outputting a normal rotation command signal when the output of the position detection means has one polarity and exceeds a first predetermined level; a second comparator circuit that has a dead band and outputs a reverse rotation command signal when the output of the position detector is of the other polarity and exceeds a second predetermined level; and a second comparator circuit that outputs the reverse rotation command signal when a stop command is received; a forward speed setting means for driving the motor at a predetermined low speed in a forward direction in response to a stop command; and a reverse speed setting means for driving the motor at a predetermined low speed in a reverse direction in response to the reverse command signal when a stop command is received. Means for stopping the motor by disabling the forward direction speed setting means and the reverse direction speed setting means when the output of the comparison circuit disappears due to the output of the speed setting means and the position detection means falling into one of the above-mentioned undesirable bands. What is claimed is: 1. A stop position control device for a moving body, comprising:
