Punch operation
The hole puncher is driven by the punch motor (M102). The home position of the hole
puncher is detected by the punch position sensor (S102) and punch HP sensor (S104). Home
position is reached when the two sensors both detect the sensor flag.
Punch operation is performed by driving the rack gear back and forth with the punch motor
(M102) and lifting the hole puncher through the punch lifter pin. The rack gear has sensor
flags and the punch operation is detected by the combination of these sensor flags and 3
sensors (punch position sensor (S102), punch 2-/3-hole sensor (S103), and punch HP sensor
(S104)).
The items controlled by the combination of sensor flags and sensors are shown below.
