Abstract

PROBLEM TO BE SOLVED: To totally cut off the cut part when an already recorded part of a roll paper which is carried by a driving roller and a pinching roller is cut by a cutter. SOLUTION: A paper discharging side of a platen which loads and guides a paper is constituted of a horizontal guide part 4a which approx. horizontally guides the paper, and a bent guide part which guides the paper downward. In the vicinity, step parts D1, D2 are formed. Both sides of a roll paper 10 on the platen are pinched by a driving roller and a pressing roller, and the roll part 10 is carried onto a plotting member 12, and a recording is performed by a recording head on the roll paper 10 on a plotting location of the plotting member 12, and after the recording, the roll paper 10 is cut by a cutter. After the cutting process, when the already recorded part of the roll paper 10 is not totally cut off, the driving roller is normally/reversely rotated, and the roll paper 10 is longitudinally moved at a high speed so that the cut applied part of the roll paper 10 may come into contact with the step parts D1, D2, and the already recorded part of the roll paper 10 is totally cut off, and dropped from the platen.

2. Description of the Related Art A drive roller and a pressure roller hold both sides of a roll paper on a platen, and the rotation of the drive roller conveys the roll paper onto a drawing member. There is conventionally known a pen plotter in which recording is performed on the roll paper by a recording head, and after recording, the roll paper is moved by a cutter in a direction crossing the roll paper to cut the roll paper. In the above conventional plotter,
The recorded portion of the roll paper may not be completely separated due to the blade edge amount of the cutter, the cutting pressure, the life of the cutter, and the like.
Therefore, the conventional plotter draws the roll paper in front of the plotter and moves the roll paper back and forth to shake off the recorded portion.

When printing is completed, a predetermined portion of the roll paper (10) is moved onto the cut groove (38) of the cut mat (34), the cutter (28) is lowered, and the carrier (26) is moved to the Y-rail ( 24), and roll paper (10)
Is disconnected. When the cut portion (42) of the roll paper 10 is incomplete and the recorded portion of the roll paper (10) does not fall from the platen (2), the cut-off portion (42) is generated based on a signal from a paper detection sensor (not shown). The controller shifts to the paper swing-down operation. This swing-down operation is performed by setting the roll paper (10) on the step portions (D1) and (D2) of the platen (2).
Roll paper (10) so that the cut portion (42) of
Is driven by forward and reverse rotation of the drive roller (14), and the cut portion (42) is moved back and forth in the AB direction within a predetermined range (W). When the incompletely cut portion (42) of the paper (10) hits the steps (D1) and (D2), pressure is applied from this portion, and the incompletely cut portion (42) is completely cut off, and the roll paper ( The recorded portion of 10) falls from the platen (2).
