ABSTRACT:
A driving mechanism of a cassette tape recorder, for inserting and ejecting a tape cassette and loading and unloading the tape of an inserted tape cassette. The driving mechanism comprises a positive motion cam having a cam groove consisting of two grooves having the shapes of circular arcs of different radiuses and different arc lengths, respectively, and a connecting groove interconnecting the two grooves, two followers suitably associated with the positive motion cam, two lever systems operatively interlocked with the two followers, respectively, and a single reversible motor interlocked with the positive motion cam. The operation of the reversible motor in the normal direction achieves a tape cassette inserting operation and a tape loading operation sequentially through the positive motion cam and the two lever systems. The operation of the reversible motor in the reverse direction achieves a tape unloading operation and a tape cassette ejecting operation sequentially through the same positive motion cam and the same lever systems.
