A group education system including a first memory for storing an original sentence group, a second memory for storing a starting address, an end address of a sentence block of an original sentence group stored in the first memory, a control circuit for controlling the selection of a playback mode and the reading order of the sentence blocks of the original sentence group stored in the first memory and the change of the pause times thereof and a third memory for storing the reading order, the starting address, the end address and the altered pause times of the selected sentence block under the control of the control circuit. Accordingly, it becomes possible to form with ease a sentence group in which the playback mode and the reproducing order of the selected sentence block are selected and the pause times between the sentence blocks are changed.

An automatic control mechanism for a tape cassette player comprises a control motor selectively rotatable in first and second directions, a cassette holder movable between a cassette load/eject position and a cassette operating position, and a head plate movable to any of a plurality of positions respectively enabling operation of the cassette player in a plurality of modes. First, second and third cams are mounted for reversible rotation by the motor. A first operating arm controlled by the first cam effects reversible movement of a tape cassette within the cassette holder between an ejected position and a loaded position. A second operating arm controlled by the second cam effects reversible movement of the cassette holder between the cassette load/eject position and the cassette operating position. A third operating arm controlled by the third cam effects reversible movement of the head plate to a selected one of the mode-enabling positions. The first, second and third operating arms are moved in a sequence which depends on the direction of rotation of the motor.
