Printer, cut paper discharge mechanism used for printer, and paper jam prevention method

摘要

A plurality of ribs are provided on a cut paper discharge guide and an upper cover which define a discharge port for discharging a cut paper. The ribs hold a cut paper in width direction. Even if a cut paper having a high degree of curl is supplied when a roll diameter of a roll paper is reduced, it is possible to prevent a paper jam such as falling or clogging of the cut paper. It is desirable that the ribs provided on the cut paper discharge guide and the upper cover are disposed in an alternate pattern along the width direction of the discharge port. This arrangement is particularly effective in a printer having an inclined paper passage.
