1Temperature Detection Sensor
Detects the temperature, to perform the black correction.
2Cassette-in Sensor
Detects the existence of a cassette.
3REC INHIBIT Sensor
Detects the REC inhibiting plug of the cassette tape.
4Tape End Sensor
Detects the end of the tape that runs in the forward direction.
5Tape Top Sensor
Detects the end of the tape that runs in the reverse direction.
6Function Cam Sensor
Detects the rotation position of a cam.
7Take-up Reel Table Rotating Sensor
Detects the rotation of the take-up reel table. The FG output signal of this sensor is input to a servo circuit so as to calculate the winding diameter of the tape.
8Cassette Lock Sensor (Switch)
Detects that the cassette compartment was locked.
9Tape Thickness Sensor
Using a tub on the back side of the cassette tape, this sensor detects the thickness of the tape wound on a cassette tape that is being inserted into the unit.
0Reel Hub Diameter Sensor
The reel hub diameter of a cassette tape varies depending on the length of the tape wound on the cassette tape. The reel hub diameter sensor detects the reel hub diameter by the tab on the back side of the cassette tape. The output signal of this sensor is input to a servo circuit so as to calculate the winding diameter of the tape.
!- Condensation Sensor
Detects whether the dew condensation occurs in the unit. != Supply Reel Table Rotating Sensor
Detects the rotation of the supply reel table. The FG output signal of this sensor is input to a servo circuit so as to calculate the winding diameter of the tape.
