Operation of the paper feeding lever
The groove cam is built into the Cam,paper feeding. Section A of the Paper feeding lever is set
on the groove cam. When the Cam,paper feeding rotates in the direction of arrow (a), the paper
feeding lever moves along the groove cam. The paper feeding lever moves with section B as the
supporting point and is amplified with the lever ratio causing section C to move up and down in
the direction of arrows (b) and(c).
