装置。 Left and right flywheels each having a capstan for driving the tape at a constant speed in the forward and reverse directions;
A magnet provided on each of the flywheels and alternately magnetized with N and S poles, and a lead wire for connecting each flywheel in parallel on the same board, and arranged opposite to each of the left and right magnets. a pole position detection element provided opposite to one of the magnets to detect the position of the pole of the magnet, and a pole position detection element that is turned on and off by a signal generated from the pole position detection element to detect the position of the pole of the magnet. A direct drive device for a tape recorder that serves as a drive circuit including a transistor that controls a drive current flowing through a coil, and a coupling means that mutually transmits and adds torque generated during rotation between the left and right flywheels.
