Sensor Circuit
(1) Media type sensor circuit
The sensor circuit consists of media sensor with six switch systems (CAS1 through
CAS6).
Loading a tape cassette, some of six 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 next page, the CPU identifies media type and size from the status of each
sensor switch.
Fig. 2.3-5 shows the media type sensor circuit.
