Abstract

PURPOSE:To prevent a magnetic field leaking from a motor from exerting an evil influence upon a magnetic tape, a magnetic head, etc., by interposing a magnetic shielding member between the rotary magnet and fixed coil of the motor, and a rotatable body for tape driving. CONSTITUTION:Stator cores 41 and 41, and 42 and 42 are arranged on a printed wiring board 33; the upper parts of the rotary spindles 39 and 40 of rotor magnets 31 and 32 pierce the printed wiring board 33, and the lower end parts are supported rotatably on a receiving member 94 stuck to the printed wiring board 33. Then, a magnetic shielding member 98 is stuck to the top surface of the printed wiring board 33 to magnetically shield a capstan motor 43, a reel motor 44, and a magnetic tape and a recording and reproducing head which are not shown in the figure.
