方向判別装置。A slit is provided in a disc that rotates together with the rotating body to be measured.
In a device in which the slit is positioned between photocouplers to generate an on/off output to the photocoupler, the shape of the slit is such that the output of the photocoupler is larger on one side in the rotation direction than on the other side. A rotating body characterized in that the output side of the photocoupler is connected to a direction discrimination circuit via two comparators that compare the output side with high and low set values and generate output signals. rotation direction determination device.
