An input device including multiple magnets rotatably disposed, multiple magnetic field detecting elements, and a controller. The magnets have the N pole and the S pole formed at a predetermined angular pitch in a rotating direction. The magnetic field detecting elements are disposed facing the magnets. The controller outputs a driving signal in response to a pulse signal output from the magnetic field detecting elements. The controller changes the driving signal to be output in response to a time difference or the number of pulses of pulse signals output from the magnetic field detecting elements.
