When a cassette is set in the cassette holder, appropriate photointerrupters (Q651,

Q652, Q653, Q654) turn on or off.

The microprocessor on the DC controller PCB identifies the presence/absence of a

cassette based on the combinations of the photointerrupters which are either on or off
(Table 5-501); accordingly, the microprocessor controls where the scanner must be
reversed or when to execute blank exposure.

(unit: mm)

1: photointerrupter is blocking light.
0: photointerrupter is not blocking light.

*size may be stored; must be within the range specified in mm; for details, see p. 10-
43.
