<p>PURPOSE:To make a tape recorder small-size by forming the opration part, which controls operations, with an electrical means. CONSTITUTION:When a tape recorder mode such as reproducing and recording is assigned by keyboard switch 80, control circuit 64 switches analogue switches 52 to 59 according to the mode and turns on or off mike 67, recording head 68 and erase head 69. Then, circuit 64 controls motor control circuit 65 to rotate motor 79 normally or reversely and switches the rotation direction of a capstan axis and a reel combined with the capstan axis, thereby switching the tape running direction. Then, circuit 64 controls motor 81 and switch 83 to move a pinchroller and a head. Thus, operations of the tape recorder are performed by the electrical means, so that the number of machine parts can be reduced, and the operational efficiency can be improved, and the tape recorder can be made small-size.</p> |
