Abstract
A power supply circuit providing voltage for operation, a motor operating powered by the output from this power supply circuit and continuing rotation powered by inertia even after loss of the output and a non-volatile memory are equipped. If the output voltage of the power supply circuit decreases, the control is continued by utilizing the voltage generated in the motor due to its inertial rotation, the data that has been used for controlling is saved on the non-volatile memory, and then access to the non-volatile memory is prohibited.
