Abstract

In the motor stop control device according to the embodiment, it is provided the main CPU 31 which executes any one of the reel stop control process 1 and the reel stop control process 2 when the stop instruction of the stepping motor 49 occurs based on an instruction from an external. In the reel stop control process 1, the main CPU 31 changes the drive power source A, which is applied to the stepping motor 49 rotating at the constant speed, to the drive power source B2 the voltage value of which is lower than that of the drive power source A and executes the stop control of the stepping motor 49 by the 2-phase excitation. And in the reel stop control process 2, the main CPU 31 changes the drive power source A, which is applied to the stepping motor 49 rotating at the constant speed, to the drive power source B1 the voltage value of which lies between the voltage values of the drive power source A and the drive power source B2 and executes the stop control of the stepping motor 49 by the 2-phase excitation.
