and PLAY/CUE/RECORD Mode. And each mode has a 4bits mode signal, which is judged by the CAM switch
which the L/C motor operates.
%
The cassette-in driving of the S1-Mecha Deck undergoes a process as follows.
- When a cassette is inserted, F/L Drive Rack falls out.
- MICOM recognizes a point of time when the light is transmitted at the Start Sensor.
- MICOM let L/C Motor drive via Motor Drive IC.

S1-MECHA Deck forces REEL to operate on the FF/REW mode and in case of other modes, it operates the
REEL SLIP.

In the FF/REW mode, S1-MECHA Deck should be operated under the unloading position to protect cassette
tapes.
