2. 2- / 3-hole Dual Use Type
At the home position, the Punch Home Position Sensor is ON. To punch two holes, punching of the first
sheet ends when the punch shaft half peripheral area has rotated in the forward direction 180°, and the
state of the Punch Home Position Sensor has changed from OFF to ON. At this time, the 3-hole
puncher is moved reciprocally in the escape direction (hole puncher rise direction) on the remaining
half peripheral area on the Punch Shaft.
Punching of the second sheet ends when the punch shaft half peripheral area has rotated in the
reverse direction 180°, and the state of the Punch Home Position Sensor has changed from OFF to
ON. Also at this time, the 3-hole puncher is moved reciprocally in the escape direction (hole puncher
rise direction) on the remaining half peripheral area on the Punch Shaft. To punch three holes, the 2-
Hole Puncher is moved reciprocally in the escape direction (hole puncher rise direction).
The following illustrates punching when two sheets are punched with two holes.
a. A hole is punched in the trailing edge of the first sheet.
