ABSTRACT:
A changeover mechanism switches the power transmission path from a single reversible motor between parts performing a cassette and tape loading function and parts performing a tape unloading and cassette ejecting function in a cassette tape recorder. The changeover mechanism has a pivotable arm supporting a drive pinion, and the free end of the arm is connected to a shiftable reversing lever through a torsion spring which is arranged to bias the pivotable lever in a bistable manner so that it is moved positively in one direction and then the other, to mesh the pinion with a positive motion cam for unloading the tape and then with a cassette driving gear for ejecting the tape cassette to an unloading position.
