5-4. Paper supply and eject drive section

The paper supply and eject drive section is consituted by a paper supply motor block ass’y and

paper supply block ass’y.

The pickup roller sends the paper in the paper supply tray.  In this stage, some papers are
conveyed.  Next, when the papers are sent to between the paper supply roller and separation roller,

only the uppermost paper is conveyed to the platen block by the paper supply roller.  The papers
later than second paper are not advanced in this position.  The reason is that the rotation of paper

supply motor is directly transmitted to the paper supply roller, but it is transmitted to the separation
roller via a P limiter gear ass’y.

When only the paper is supplied, the separation roller is pressed against the paper supply roller.
When there is one paper or nothing, the drive paper conveyed directly from the paper supply roller

to the separation roller becomes higher than that from a torgue limiter (P limiter gear assy).  There
fore, gears BAND A of the P limiter gear assy are slipped and the separation roller is rotated in the

forward diretion.  But when more than two papers are put between the paper supply roller and
separation roller, gears A and B of P limiter gear ass’y are rotated in same direction and the

separation roller is rotated reversely since the direct transmission drive power from the paper
supply roller to separation roller becomes weak due to the slipped paper and since, the drive power

from the P limiter gear becomes higher.  When one piece, the paper is conveyed since the
separation roller is rotated in the forward direction.  When more than two pieces, only the

uppermost paper is conveyed and later two pieces are returned since the separation roller is rotated
reversely.

Lastly, the printed paper is conveyed to the paper eject section by the paper eject roller.
