<p>PURPOSE:To obtain a compact and lightweight loading mechanism, by setting rotatably a lever attached with an impedance roll and a head substrate to a chassis on the same axis. CONSTITUTION:A rotary lever 6 loading a sound head 7 and a postrecording erasion head 8 is fixed to a chassis and attached rotatably to a fixed shaft 6a. At the same time, a lever 11 attached with an impedance roll 5 is supported rotatably by the shaft 6a and energized clockwise with a spring 10. Therefore the rotary fulcrum of a head substrate loading magnetic heads 7 and 8 and the fulcrum of the impedance roll lever 11 exist at the common shaft 6a. In such a way, a compact and lightweight structure is attained for is loading mechanism.</p> |
