[ 3 ] Identification of Tape Cassette Type
The cassette sensor PCB has four sensor switches (SW2, SW3, SW6 and SW7).
Loading a tape cassette turns on some of those switches while keeping others off
depending upon the ID encoding holes provided in the tape cassette currently loaded.
If an encoding ID hole is closed, the corresponding sensor switch goes on.
With the states of those sensor switches, the CPU identifies the tape width and tape
cassette type, as listed below.

0: Switch OFF (ID hole opened)
