Cutter Mechanism

This is an autocutting mechanism that cuts the roll paper with the driving force of the motor and
has an emergency cutter to cut roll paper manually.

Autocutter Mechanism

The basic idea of the autocutter mechanism on this printer is the "scissors principle" to cut paper
at the intersection of two blades. The autocutter on this printer has one stationary blade and two
movable blades: a scissors blade that moves rotatively and a sliding blade that moves in a
straight line. In operation, it employs a compound blade type autocutter mechanism that leaves
the area between the scissors blade and the sliding blade uncut. The structure requires that the
stationary blade, the scissors blade and the sliding blade be established on the cutter frame and
the drive mechanism be established on the cutter cover.
