2.3.1 Media Type Detect Sensor Circuit, Media Position Detect Sensor Circuit and
Cover Open Sensor Circuit
(1) Media type detect sensor circuit
The sensor circuit consists of media sensor with five switch systems (CAS1
through CAS5). Loading a tape cassette, some of five switches turn on and the
others retain off according to the configuration of its' ID code apertures. Clogged
ID apertures turn on the corresponding sensor switches.
As shown Table 2.3-1, the CPU identifies media type and size from the status of
each sensor switch.
