to the servo circuit to control the threading speed so
that the tape is not damaged during threading and
unthreading.
2Threading-end/unthreading-end sensor
This sensor detects whether the threading ring reaches
the threading-end or unthreading-end position.
3T tension regulator arm sensor
During recording and playback, this sensor detects the
tension arm position and controls the reel torque to
keep a constant T tape tension.
4Condensation sensor
This sensor detects whether the dew condensation
occurs in the unit.
5Tape top sensor
This sensor detects the top of the tape, and in addition
detects the tape end of the tape that runs in the rewind
direction.
