This circuit detects the type of film cartridge.
The Cartridge type detector switch CSIZE3 is mounted at the film cartridge inlet.
When an A3 film cartridge is inserted, the A3 film cartridge presses the Cartridge
type detector switch CSIZE3 and turns it ON (P14 becomes LOW).
The Cartridge type detector switch CSIZE4 is mounted at the film cartridge inlet.
When an A4 film cartridge is inserted, the A4 film cartridge presses the Cartridge
type detector switch CSIZE4 and turns it ON (P20 becomes LOW).
The Cartridge type detector switches remain OFF when an A6 film cartridge is
inserted and when no film cartridge is inserted.
