BJC-50
1.5 Scanner Drive
The scanner cartridge is recognized by the scanner cartridge contacts and TOP.S,
C.CHA and C.CHK signals. These three signals are equivalent to the TOP, DIODE A
and DIODE K signals of the BJ cartridge.
Color distinction is performed by ID 0 and ID 1 as in the BJ cartridge.
The three signals, CMD 0 (REN), CMD 1 (RWR) and CMD 3 (RDT) are used to set data
in the scanner resistor. These signals correspond with the ODD ENB, BENB 0 and
BENB 1 signals of the BJ cartridge. Together with a clock signal, serial data is output
to the resistor.
Data scanned with a scanner cartridge is output by S.SCLOCK (DTCK), S.SYNC (LNST)
and S.DATA (DT). The scanner cartridge is operated when the S.SYNC (LNST) signal is
inputted.
The scanning dot data set in the resistor is output as serial data in sync with a clock
signal.
