Cutter Guard with Receipt Holding Function

      Disclosed is a safety guard device which has the ability to
protect the operator from touching the cutter blade which is
installed in a receipt printer.

The blade is moved by motor, and this cutter guard has two more
functions:
  1.  The cut receipt does not drop back to a cut position to
       avoid double cutting.
  2.  The cut receipt does not drop out of printer.

      Fig. 1 shows this device composition.  The hatching portion is
the cutter guard.  The cutter is composed of a fixed blade and a
moving one.  "C" is the cut position; "R" is the maximum radius of
the curl of  the receipt roll paper; "r" is the minimum one.  In this
device, the cutter guard's shape is designed so that both circles
whose radiuses are R and r passes through points "A" and "B" and the
upper surface of  the fixed blade.  Then, the cut receipt does not
drop back to the cut position in all curl radius.

      Fig. 2 shows the case of a long-receipt issued.  It does not
drop out because the cutter guard holds it with the friction of
points "A" and "B".
