8.1.4 Outline of the Pickup Assembly Motor Control System

The machine uses 12 stepping motors of a 2-phase excitation type.
Each of these motors is supplied with 24-V power by the motor drive PCB, and is turned on and off by the pulse signals from the DC controller PCB; its
direction of rotation is also controlled by the DC controller PCB.
The following shows the motors used in the machine's pickup assembly, and the diagram that follows shows the control circuit used for the cassette 3/4
pickup motor (representative of all pickup motor control circuits):
