c. Moving Up/Down (pick-up) the Pick-Up Roller
The pick-up roller and the feeding roller are supported by a roller holder, and the pick-up roller oper-
ates around the feeding roller shaft. The up/down movement of the pick-up roller shaft is driven using the
drive of the main motor (M1) through the cam 1 controlled by the pick-up solenoid (SL2).
In standby, the pick-up roller shaft is at uppermost position. The following operations take place when
picking up a single sheet of copy paper:
1. When the pick-up solenoid (SL2) turns ON, the drive of the main motor (M1) causes the cam 1 to make
a single rotation.
2. The single rotation of the cam causes the pick-up lever to swing.
3. As the lever swings, the pick-up roller shaft lowers once to come into contact with the copy paper, and
the drive of the pick-up motor (M4) is used to pick-up a single sheet of paper.
4. The rotation of the cam 1 raises the pick-up roller shaft.
