Saddle stitching hold control

A.

Mechanism

The saddle stitching hold is the mechanism to prevent the paper misalignment at stapling. The saddle stitching
hold /Up [1] moves down to the saddle stitching hold /Lw [2] at its lower position and hold the center folded
paper [3] at the fold line from both up and down.
The eccentric cam [5] moves the saddle stitching hold /Up [1] up and down via the arm [6].
