<p>PURPOSE:To miniaturize a device without using a loading motor, a mode switch, and a transmission gear, etc., by fixing a coil unit on a metallic substrate, fixing with a spindle a rotary plate on which a permanent magnet is fixed rotatably by confronting it with the coil unit, and linking a tape draw out member to it. CONSTITUTION:The coil units 37 and 38 are fixed on the metallic substrate 28, and the rotary plates 30 and 31 on which the permanent magnets 35 and 36 are fixed are confronted with the coil units 37 and 38, and are fixed with the spindle on the metallic substrate 28 so as to be coaxial-rotated with arms 9 and 10. The arms 9 and 10 are rotated by the driving forces of the permanent magnets 35 and 36 which rotate by reacting with a magnetic field generated by currents on the coil units 37 and 38, and the tape draw out members 3 and 4 are moved via loading links 7 and 8. In such a way, it is possible to perform loading drive and to miniaturize the device without using the loading motor, the mode switch, or another driving gear.</p> |
