Patent attributes
A printer having a paper discharge mechanism which reliably prevents recording paper after completion of the printing operation from being pulled back inside the printer. The printer includes a paper feed roller 62 located on the upstream side of the printing position 83 along the horizontal paper transportation path of the printer. A paper cutting mechanism 67 is located downstream from the printing position. A pressure roller 66 presses the recording paper against a discharge roller 65 from the top side of the paper transportation path. A reversing-prevention lever 80 is disposed coaxially and freely rotatably to the pressure roller 66. The center of gravity of the reversing-prevention lever 80 is downstream from the axis of rotation 66e of the pressure roller 66, and the weight of the reversing-prevention lever 80 causes the reversing-prevention lever 80 to contact the top of the discharged paper 10. If the trailing end of the cut and discharged paper 100, which rests on top of the leading end of the roll paper 10, moves with the leading end of the roll paper 10 when the roll paper 10 is pulled back inside the printer after cutting, the trailing end of the discharged paper 100 contacts the reversing-prevention lever 80 and is thus prevented from being pulled back inside the printer.
