In the motor stop control device according to the embodiment, a main CPU is provided which executes any one of reel stop control process 1 and the reel stop control process 2 when the stop instruction of a stepping motor occurs. In the reel stop control process 1, 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 B2, 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 2, 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 B1,the voltage value of which is 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 by the 2-phase excitation.
