Abstract
A signal processing circuit for a rotation detector includes a rotational direction determining portion, an effective edge determining portion, a normal-rotation pulse request holding portion, a reverse-rotation pulse request holding portion, an output request signal outputting portion, a pulse outputting portion, a first resetting portion, and a second resetting portion. When one of the holding portions holds an output request signal, the pulse outputting portion outputs a pulse based on the output request signal. When the other one of the holding portions holds an output request signal and then a condition for holding the output request signal that is already held by the one of the holding portions is satisfied in a state where the one of the holding portions holds the output request signal, the second resetting portion resets the output request signal held by the other one of the holding portion.
