Abstract
The invention is intended to allow a motor to be driven normally even when an output voltage of a primary power source unit varies. A motor drive control unit configured to attenuate a charge of a secondary cell by an electromotive force of a solar cell to a level lower than the charge at that moment before driving the motor, and then intensify the charge of a level higher than the charge at that moment after having driven the motor is provided.
Claims20
A drive control apparatus comprising a motor drive control unit configured to attenuate a charge of a secondary power source unit by an electromotive force of a primary power source unit while a motor is driven in comparison with a case where the motor is not driven.
