Abstract
In the motor stop control device according to the embodiment, a main CPU is provided which executes any one of reel stop control processand the reel stop control processwhen the stop instruction of a stepping motor occurs. In the reel stop control process, the main CPU changes a drive power source A, which is applied to the stepping motor rotating at the constant speed, to the drive power source B, the voltage value of which is lower that that of the drive power source A, and executes the stop control of the stepping motor by the 2-phase excitation. In the reel stop control process, the main CPU changes the drive power source A, which is applied to the stepping motor rotating at the constant speed, to the drive power source B,the voltage value of which is between the voltage values of the drive power source A and the drive power source B, and executes the stop control of the stepping motor by the 2-phase excitation.
