Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a brush plotter that drives and controls a brush on a printing paper in three directions of XYZ continuously to draw a brush character. The present invention relates to a paper pressing device that presses a printing paper on a base surface by a paper pressing.

(Prior Art) In a conventional plotter, a writing instrument is continuously driven and controlled in a front-rear direction, a left-right direction, that is, an XY direction on a plane parallel to a printing sheet, and a writing end whose tip is abutted on the printing sheet in the vertical direction, that is, the Z direction. Two-position control is performed to reciprocate between the character position and the non-character position away from the printing paper, and even if a handwriting is used as a writing tool, the writing pressure is constant, so it is not possible to draw a character unique to a writing brush. It was

On the other hand, a writing brush is used, and the writing pressure on the printing paper is continuously changed by continuously controlling the driving in the Z direction in addition to the XY directions.
A brush plotter as shown in the figure has been developed.

Reference numeral 1 is a base on which a printing paper 17 is placed, and a Y-axis carriage 3 is mounted on two Y-guide shafts 2 mounted in parallel with each other on the base 1 so as to be slidable in the Y-direction.

Two X guide shafts 5 parallel to each other are mounted on the Y-direction carriage 3, and an X-axis carriage 6 is mounted on the X guide shafts so as to be slidable in the X-axis direction to form an XY mechanism. ing.

A Z mechanism supporting arm 8 extending in the X axis direction is mounted on the X axis carriage 6 which is movable in the XY directions of the XY mechanism, and a Z pulse motor 14 and a writing brush 11 are attached to the tip of the Z mechanism supporting arm 8. And a brush holder 16 for holding the
The mechanism is attached via a support plate 15.

Therefore, the brush 11 is the belt 4 driven by the Y pulse motor 12.
Drive control in the Y direction via X, drive control in the X direction via the wire 7 by the X pulse motor 13, Z pulse motor
By the drive control in the Z direction by 14, the brush characters are continuously driven in the three directions of XYZ, and the brush character is drawn on the printing paper 17 arranged on the base 1.

In the brush plotter configured as described above, in order to stably draw good brush characters, the drive control in the Z direction is precisely performed, and the printing paper 17 is brought into close contact with the surface of the substrate 1 by the drawing portion. A paper presser is placed near the.

(Problems to be Solved by the Invention) As described above, the Z mechanism is supported by the foot portion 10 of the position plate 9, and the foot portion 10 slides on the surface of the base body 1 when drawing. If the paper retainer is placed on this sliding portion, the writing will be obstructed as in the case of being placed on the drawing portion.

For example, as shown in FIG. 6, when the address is written on the envelope 18, the postal code, address, name, etc. are drawn by defining the character arrangement by the automatic layout mechanism.
The locus on which the foot portion 10 slides is in the range of 19, 20, and 21 surrounded by the solid line, and if the paper retainer is placed on this portion together with the drawing portion, the drawing will be obstructed.

However, in the past, it was not clear where the paper presser was placed when the paper presser was placed, so that the paper presser may be placed on this part to cause an error in the character printout.

In order to solve the above-mentioned problems of the prior art, the present invention performs automatic layout to determine the optimum character arrangement for the printing paper at the time of drawing, and at the same time places a paper presser that does not interfere with drawing. The purpose is to provide a brush plotter whose possible range is clearly defined.

(Means for Solving the Problem) That is, the present invention provides a brush plotter for drawing a brush character by continuously controlling the handwriting held in the brush holding portion in the three directions of XYZ with respect to the printing paper. Paper pressing range determining means for determining a mountable range of the paper pressing that does not hinder the drawing according to the character arrangement determined by the automatic layout mechanism configured by means for storing, selecting and determining the arrangement, and A paper pressing device for a writing plotter, comprising: paper pressing range display means for displaying the paper pressing range determined by the paper pressing range determining means.

(Action) The present invention is configured as described above, and its action is to draw a character according to a character arrangement defined by an automatic layout mechanism including means for storing, selecting and determining a character arrangement. Since the mountable range is defined and this is displayed, it is possible to easily mount the paper presser at a position where it does not interfere with drawing.
