[ 2 ] Cassette Sensor
The sensor circuit consists of a 7-switch cassette sensor (SW1 through SW7).
Loading a tape cassette turns on some of those seven switches on the cassette sensor
while keeping other switches 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, ink ribbon
type of the tape cassette, as listed in Table 2.2-1.
Table 2.2-1 Coded Values for Identifying Tape Cassette Type
* The tape cassette type is detected by the detecting switches provided in the machine
and the hole provided in the tape cassette.
