Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an X-Y plotter device that draws lines and characters on paper by moving a writing instrument and paper in the X and Y directions.

BACKGROUND TECHNOLOGY As shown in FIG. 8, a paper feed roll 3 formed by pressing a drive roll 1 and a presser roll 2 is used to transport a paper sheet.
is movable in the X direction, and the writing instrument 5 is movable in the Y direction by a moving mechanism (not shown), and the paper feed roll 3 and the writing instrument 5 are moved in the X and Y directions based on input data with the writing instrument 5 as the origin position. A so-called paper-driven X-Y plotter device is known that moves to draw a desired figure.

Problems to be Solved by the Invention With such an X-Y plotter device, a gripping allowance is required for the paper feed roll 3, and a writing instrument 5 is required.
are arranged at a slight distance from each other so as not to interfere with the paper feed roll 3, so that a portion 4' where drawing cannot be made occurs at one edge of the paper 4 in the feeding direction, as shown in FIG.

On the other hand, on the paper 4, a frame 4b is drawn so as to have a binding margin 4a on the left side as shown in FIG. 9, or a frame 4b is drawn so as to have a binding margin 4a on the right side as shown in FIG. There is something.

For this reason, if the paper 4 has a binding margin 4a on the left side as shown in FIG. 9, it is possible to draw across the entire frame 4b, but if the paper 4 has a binding margin 4a on the right side as shown in FIG. If so, drawing cannot be performed on the left side of the frame 4b.

In addition, as shown in Figure 11, there is a binding margin 4 on the right side.
If paper 4 with a is set with the left and right sides reversed, a drawing can be drawn across the entire frame 4b, but if this is done, the drawn figure will be upside down.

In other words, the top and bottom of the paper 4 are determined by the frame 4b, and the paper 4 and writing instrument 5 move in the X and Y directions based on the input data, so for example, when drawing a convex figure, When the data is input, a convex figure is drawn on paper 4, and
When viewed from above and below, it becomes a cross-shaped figure.

Means and operation for solving the problem The calculation command circuit that outputs X and Y direction movement data to the paper feed roll and writing instrument based on input drawing command data has a binding margin on the opposite side of the paper from the paper feed roll. A key input unit is provided to output commands to reverse the signs (+) and (-) of the X and Y direction movement data when drawing by moving the paper feed roll and writing instrument in the direction based on the input drawing command data. This allows it to move in the opposite direction.

Embodiment FIG. 1 and FIG. 2 are overall schematic front views and plan views, and show a drive roll 11 driven by a first motor 10.
Press the presser roll 12 against the paper feed roll 1.
3, and this paper feed roll 13 moves the paper 14 to
The second motor 16 moves the writing instrument 17 along the main body 15 in the Y direction.
It is provided so as to be movable in the Y direction, and can be moved up and down by a solenoid 18.

FIG. 3 is a control circuit diagram, in which plotting command data sent from a data command section, for example a personal computer 20, is inputted to an arithmetic command circuit, exemplified as a CPU 22, via an interface 21.
The CPU 22 decodes the input drawing command data, performs calculations, converts it into X-direction movement data, Y-direction movement data, and writing instrument vertical data, and sends the data to the drive unit 22.
is input to the first and second motors 1 from the drive unit 23.
0, 16 and solenoid 18.

24 is a key input section, which is equipped with a coordinate system selection switch 25, which selects the standard coordinate system and 180
Either one of the °C rotational coordinate systems is input to the CPU 22, and when the standard coordinate system is input, the CPU 22 directly outputs the X and Y direction movement data based on the drawing command data to the drive unit 23,
When a 180° rotation coordinate system is input, (+) of the X and Y direction movement data based on the drawing command data,
The (-) signs are respectively inverted and output to the drive section 23. If this operation is shown in a flowchart, the fourth
The result will be as shown in the figure.

Therefore, for example, when drawing command data such as drawing a straight line A of P ₀ → P ₁ → P ₂ → P ₃ as shown in Figure 5 is input, if the standard coordinate system is input, P (+) such as located at ₀ , P ₁ , P ₂ , P ₃
When the X, Y direction movement data of
The sign of the directional movement data is converted into (+) and (-) and input to the drive unit 23, thereby P ₀ , P′ ₁ ,
Move to the positions P′ ₂ and P′ ₃ and move P′ ₀ →P′ ₁ →
We will draw straight line B of P' ₂ → P' ₃ , that is, a straight line rotated 180 degrees symmetrical to straight line A.

Therefore, as shown in FIG.
In the case of 4, the binding margin 14a is set to the left side, that is, the paper feed roll 13 side, and the writing instrument 17 is set with the lower left as the origin position 0.

In this state, the personal computer 20 outputs drawing command data to draw a convex figure, and the coordinate system selection switch 25 selects the standard coordinate system.
A convex figure can be drawn on the paper 14 by outputting (+) and (-) sign X and Y direction movement data based on the input drawing data command to the CPU 22.

If a frame 14b is drawn in which the binding margin 14a is on the right side, as shown in FIG. Set position 0 to be at the top right, and press the coordinate system selection switch 25.
By inputting the 180° rotating coordinate system to the CPU 22 and outputting the X and Y direction movement data with opposite signs of (+) and (-) based on the drawing command data, it is possible to draw a 〓 shape on the paper 14. , if the paper 14 is turned upside down, it becomes a convex figure.

Effects of the Invention When drawing a sheet with a binding margin on the opposite side of the paper feed roll, the X and Y direction movement data output from the arithmetic command circuit can be output with opposite signs (+) and (-). The paper 14 and writing instrument 17 can be moved in the opposite direction to the direction based on the input drawing command data.

Therefore, even if the binding margin is on the side of the paper feed roll, or on the paper with the paper on the opposite side of the paper feed roll, it is possible to draw across the entire frame, and the drawn figure will not be upside down.
