3.2.10 Cassette Sensor Circuit - Brother P-touch PT-1180 Service Manual

3.2.10 Cassette Sensor Circuit

Fig. 3.2-20 shows the cassette sensor circuit. This circuit detects each of the five sensor switches
which is pushed or not depending upon the ID holes provided on a tape cassette currently
mounted.
By perceiving the states of those sensor switches, the CPU identifies the tape cassette type (the
varieties and the widths).
If an ID hole is open, the sensor switch is not pushed.
Table 3.2-1 lists the coded values for identifying the tape cassette type.
