8.1.3 Paper separation operation
Since no paper separation claws are used in the
cassette, a paper separation roller is installed in-
side the machine. The separation roller section
consists of a paper feed roller, separation roller,
spring joint, etc., as shown.
The feed roller is rotated by the feed clutch in the
direction of the arrow ( ) at the same timing as
the pick-up roller.
As shown in the lower right figure, the feeding of
two sheets occurs. Since the friction between the
sheets is smaller, the lower sheet is stopped being
fed any further while the upper sheet is forced to
be transported by the feed roller in the direction of
the arrow ( ).
[Example]
When only one sheet of paper 1 has entered into
the separation roller section, since the feed roller’s
transporting force is stronger than the separation
roller’s braking force, the separation roller is forced
to rotate causing the sheet to be sent toward the
aligning roller ( ).
When, two sheets ( 1 and 2 ) have entered into
the separation roller section at the same time, since
the powers of the feed roller’s transpor ting and
separation roller’s braking are greater than the fric-
tion power of the paper, the paper 1 is transported
in the direction of the arrow ( ) and the paper
2 is not transported any further by the separation
roller.
