Overview and Operating Principle 1-13
Figure 1-14 Fast Paper Feeding
Operation of Gear,paper feeding drive and Gear,paper feeding (Refer to Figs. 1.15 and 1.16.)
The Gear,paper feeding drive engages with the Paper feeding lever, then Gear,paper feeding
drive rotates again in the direction of arrows (a) and (b) in relation to the vertical movement of
the paper feeding lever (in the direction of arrows (c) and (d)). Conversely, the Gear,paper
feeding which engages with the Gear,paper feeding drive meshes with the Gear,paper feeding
drive in one direction only to perform intermittent rotation in the direction of arrow (f).
Paper feeding condition (Refer to Fig. 1.15)
When the paper feeding lever is pulled in the direction of arrow (a) by the groove cam section of
the Cam,paper feeding, the Gear,paper feeding drive rotates in the direction of arrow (e) to
mesh with the Gear,paper feeding. This causes the Gear,paper feeding to rotate intermittently
one or two teeth in the direction of arrow (f), and the Roller,paper feeding mounted on the same
shaft as the paper feeding gear rotates simultaneously in the direction of arrow (d) to feed paper.
