Title:
PAPER DRIVING METHOD FOR PAPER-DRIVING TYPE PLOTTER
Document Type and Number:
Japanese Patent JPH0761190
Kind Code:
A
Abstract:

PURPOSE: To solve deterioration of image quality because of the unsettling condition of a paper by means of a software of a controller by lowering the speed of acceleration of plotting to the given value based on the angle and length of a segment data to be plotted and the action of drawing up a hanging- down section of the paper.

CONSTITUTION: A paper 4 placed on the upper face of a paper placing stand 2 is gripped by a driving roller 6 and a punch roller 8 and driven in the left and right direction X by the forward and reverse rotation of the driving roller 6. A writing tool 10 set above the paper placing stand 2 is disposed to be movable in the vertical direction Y so that its end is brought into contact with and away from the upper face of the paper 4. In that case, for the purpose of driving the paper 4, whether the angle made by a segment data to be plotted to the Y axis is the given value or more and the length is the given value or less is judged. Then whether the segment data to be plotted accompanies the action of drawing up a handing-down section of the paper or not is judged. Successively when the judgment result is all positive, the speed and acceleration of plotting are lowered to the given values.
