<Playback Stand-by (Stop) mode>
(1) The tape loading operation completes and the loading motor stops.
(2) In the same way as in the playback mode, the capstan motor rotates in forward direction and the T reel
disc takes up the tape. (For more details, refer to the playback mode.)
(3) After running the tape for 0.6s, the mechanism rotates the capstan in the reverse direction for 0.3s to
slack the tape properly with pinch roller pressed.
(4) If nothing is operated for about 5 minutes, the loading motor rotates in the forward direction and the cam
position reaches the position V, and both the loading motor and the cylinder motor stop.
(5) During this period, the video and audio systems are in the same status as in the stop mode.
[2] Tape unloading & Cassette unloading
<Tape Unloading>
(1) When the [EJECT] button is pressed in the stop mode, the mechanism enters the eject mode.
(2) IC601 controls cylinder motor drive IC to make the cylinder motor rotates.
(3) IC601 makes the loading motor rotate in the reverse direction, and shifts the cam slider.
1) The mechanism components move in the reverse direction against the loading operation.
(4) When the cam slider reaches the position II, IC601 makes the capstan motor rotate in the reverse direction
(LP X11) and takes up the tape at a specified torque using the clutch mechanism.
(5) When the cam slider reaches the position I, it brakes the capstan motor to stop, and then stops the loading
motor after 230ms passed.
<Cassette unloading>
(1) Furthermore, IC601 makes the loading motor rotate in the reverse direction and also the capstan motor in
reverse direction, applies braking force to the capstan motor by detecting the tape start sensor
OFF --> ON, and the capstan motor stops.
(2) IC601 makes the loading motor stop after 150ms passed from sensing “ON”.
(3) Also IC601 makes the loading motor rotate in the forward direction after 120ms passed.
