Abstract

Disclosed is a mechanism of 'Page Slip' reformer for Passbook Printer. The disclosed mechanism acts on the printing page of an opened passbook to correct the top edge displacement of the page against the top edge of another passbook pages by rotating an upper roller at a peripheral speed more than that of a main feed roller.

'Page Slip' Reformer for Passbook Printer

      Disclosed is a mechanism of 'Page Slip' reformer for Passbook
Printer.  The disclosed mechanism acts on the printing page of an
opened passbook to correct the top edge displacement of the page
against the top edge of another passbook pages by rotating an upper
roller at a peripheral speed more than that of a main feed roller.

      The slippage as described above occurs while the passbook is
fed through the media feed mechanism on its way to the print unit.
This 'Page Slip' leads to poor print line registration and in turn
leads to poor print quality.  The disclosed mechanism effectively
eliminates such 'Page Slip' and helps improve the overall print
quality.

      The figure shows each component of this mechanism.  It consists
of Main Feed Rollers 1, Upper Roller 2, for reforming 'Page Slip',
Electro-magnetic Clutch 3, Passbook 4, and Media Sensor 5.  After
Media Sensor 5 detects Passbook 4, Control Circuit activates
Electro-magnetic Clutch 3 for a specific period of time to drive
Upper Roller 2.  Upper Roller 2 rotates at a peripheral speed more
than that of Main Feed Rollers 1.  This speed difference of the
rollers reforms the 'Page Slip'.  Upper roller 2 functions as an idle
pinch roller while Electro-magnetic Clutch 3 is not activated.

      Braking of Main Feed Rollers 1 for a specific period of time
while continuously driving Upper Roller 2 is an alternative method to
achieve the same result.
