ABSTRACT:
A drive control device for a brushless motor having a rotor and a plurality of coils with different phases can be included in an image reading apparatus or an image forming apparatus. The drive control device may include a detection target configured to rotate in synchronization with rotation of the rotor and having formed thereon a pattern representing modulation information, a detector configured to read the pattern and to output modulated output signals, a demodulator configured to demodulate the modulated output signals and to obtain demodulated information, and a controller configured to control rotation of the rotor on the basis of at least the demodulated information obtained by the demodulator.
