Printer

A printer for pulling out a paper wound in a form of a wound roll, comprising:

• a cartridge configured to accommodate the paper;
• a housing in which the cartridge is mounted;
• a cover moveable between an open position for opening the top surface of the housing and a closed position for closing the top surface of the housing;
• a first printing unit mounted to the housing;
• and
• a second printing unit mounted to the cover,
• wherein the paper is configured to be pulled out between the first printing unit and the second printing unit, and
• wherein the second printing unit comprises:
• a protrusion-shaped decurling part having a first curvature radius, and configured to surface-contact with an upper side of the paper in a process of pulling out the paper when the cover is in the closed position;
• and
• a paper guide part having an inclined surface configured to surface-contact with the upper side of the paper in the process of pulling out the paper when the cover is in the closed position, and
• wherein a first height from a bottom surface of the housing to a first center of the first curvature radius of the protrusion-shaped decurling part is greater than a second height from the bottom surface of the housing to an upper end portion of the inclined surface of the paper guide part, and
• wherein the decurling part is configured to press the paper such that a portion of the paper, contacted with the decurling part, is angled at an obtuse angle.
