Sensor control section
Two types of sensors are provided, a magazine up sensor and a mark sensor.
Signals of the magazine up sensor are output from pin No. 2 of the
connector P4. If the magazine opens, the switch is turned off, and an “L”
level signal is transmitted to the FPGA. While the magazine is closed, an
“H” level signal is output.
Signals of the mark sensor are output from pins Nos. 1 and 2 of the
connector 6. Signals for detecting the mark of the recording paper are
output from pin No.1, and those for judging the presence of the recording
paper are output from pin No. 2. If the mark of the recording paper touches
the sensor, or recording paper is not provided, an “L” level signal is output.
The signal is then amplified to about 5 times the original signal with
µ
PC358G2 (IC38) and transmitted to the CPU.
