2. The cassette tape pushes the draw-in lever. Then the load switch is turned ON via the draw-in arm and load buffer
lever.
3. The sub motor starts running.
4. The sub motor turns the mode gear. Then the mode gear moves the load drive lever and load buffer lever.
5. The shaft holder of the load buffer lever rotates the draw-in arm to draw in the cassette tape.
- Eject operation
1. The cassette tape is ejected in accordance with the reverse of the loading operations. After that, the load switch is
turned OFF and the sub motor stops rotating.

1.3 LOADING AND EJECT OPERATIONS(2)
- Loading operation
1. When the mode gear rotates, the load drive lever moves in the direction B marked with an arrow in the figure.
2. As the load buffer lever is linked with the load drive lever via a spring, the load buffer lever turns the draw-in arm
in the cassette.
- Eject operation
1.
Eject operation is done in accordance with the reverse of the loading operation.

The mode gear is rotated by rotation of the pre mode gear which is driven by the sub-motor.
The modes are in series in the order of "release"rt"forward play"rt"REW"rt"FF"rt"reverse play".
The rotation of the mode gear makes changeover of the head position, press contact between the pinch rollers(for-
ward, reverse), the rewinding reel rotation, etc.
The actions to be performed in the separate mode are show in Fig.1 through 5.
