ABSTRACT:
A magnetic recording and reproducing apparatus has a tape loading mechanism for pulling out a magnetic tape incorporated in a cassette which is loaded in position. A driving motor for the tape loading mechanism is also employed for changing over operation modes of the apparatus, thereby realizing a mechanism which is greatly reduced in size. In particular, power from the driving motor is transmitted to tape loading device through a worm and a worm gear. The worm is adapted to be axially slidable. An operation mode changeover device is moved by sliding the worm. When the tape loading device have pulled out the tape to a predetermined position by the rotation of the driving motor, the tape loading operation is stopped. By further rotating the worm either forwardly or backwardly in relation to the worm wheel which is stopped, the worm slides to set, the mechanism in an operation mode selected from the stop mode, the reproducing mode, the high-speed feed mode and so forth by means of the operation mode changeover device.
