Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides an interactive automatic J! 1!
Regarding the drawing machine, in detail, it is an interactive automatic drawing system that improves operability by separating the operation surface where the operator uses a cursor to detect the position #, , and the drawing surface using a pen for drawing. There's something about machines.

[Background of the invention]

The interactive automatic drafting machine with a coordinate detector is
As shown in the figure, an operation surface 22 on which an operator detects coordinates using a cursor 21 and a drawing surface 23 on which a pen 24 of an automatic drafting machine moves to draw a drawing completely overlap. For this purpose, the coordinates are detected by the cursor 21,
Not only does this have poor operability when inputting data, but it also poses a safety problem when drawing with the pen 24.

□As shown in Fig. 1, a wire 26 is stretched for the purpose of making the operation surface easier to see, and the pen 24 is pivotally connected to the wire 26, which results in poor drawing quality. Since the frictional load increases, the drive system must be made stronger, which leaves the problem of increased costs.

Furthermore, as shown in FIG. 2, in order to improve the drawing quality, if the holding part of the pen 24 is made of a rod-shaped member 25 so as to give rigidity to the mechanical system for driving the pen, the inertia of the movable part increases. However, there was a drawback that the drawing speed was slow.

[Purpose of the invention]

An object of the present invention is to eliminate the problems of the prior art described above.
An object of the present invention is to provide an interactive automatic drafting machine that has improved safety and operability, and also enables improvement in drawing speed, quality, and cost reduction of a drive system.

[Summary of the invention]

In order to solve the above problems, it is first necessary to separate the drawing screen and the operation surface for coordinate detection in order to improve stability and operability. As a necessary condition, each coordinate on the drawing surface must match each coordinate on the operation surface, that is, each coordinate on the coordinate detector.

In order to solve this problem, in the present invention, a coordinate rendering device? i-In addition to being fixed to the main body of the drawing machine, the media that was previously attached to the coordinate detector with tape etc.
By having a structure that is separated from the coordinate detector and by freely moving the media, it is possible to move the drawing specified on the operation surface to a drawing surface that is separate from the operation surface. This configuration allows the media to be returned. At this time, the coordinate origin of the drawing surface and the coordinate origin of the operating surface always have a certain distance, but by correcting this distance through software processing, the coordinates of the drawing surface and the coordinates of the operating surface are made to perfectly match. This is what I did.

[Embodiments of the invention]

Hereinafter, practical examples of the present invention will be described in detail with reference to FIGS. 3 to S. FIG. 3 is a specific circuit diagram of the system configuration, and FIG. 4 is a perspective view of a main part of a driving section driven in the circuit of FIG. 3. The same reference numerals in FIGS. 3 and 4 indicate the same parts.

In these figures, 5 is the drive control section of the automatic drafting machine, and the parts controlled by it include the X-axis of the motor 1;
That is, as shown in FIG. 4, there is a motor 1 that rotates a belt on which media is pasted in the vertical direction. Also,
The motor 2IIi is for driving the Y-axis, that is, the object to which the pen 3' is attached in the left-right direction, as shown in FIG. Reference numeral 3 denotes a bay control unit which has the function of controlling the up and down movement of the pen 3' and bringing the pen 3' into contact with the media, and is composed of a magnet, a coil, and a pen holder. Reference numeral 4 denotes a pen exchange unit for exchanging the pen 3' attached to the pen control section 3. 1 is a coordinate detection device;
As shown in FIG. 4, the belt 11 is inserted between the belts.
This is a device for detecting coordinates artificially specified by a cursor from above the media. 6 is a central processing unit. 8 is a CRT (including keyboard),
It has the function of inputting operator commands to the central processing unit 6 or displaying messages from the central processing unit 6. Reference numeral 9 denotes a floppy disk for storing and outputting graphic data after graphic processing.

Now, in FIG. 4, by driving the motor 1, the roller 10 is rotated through a gear, and by driving the belt 11 connected to this roller by a sprocket system, a tape is pasted on the upper surface of the belt 11. The media 12 can be driven vertically. With this configuration, media 12
When an operator wishes to draw rABCDJ at a certain point above, for example, he specifies one or two points within the range to draw rA B CDJ using the curve 13, and reports the coordinates to the central processing unit 6. The operator also inputs a command to draw ABCDJ using the CRT 8, and the information is input to the central processing unit 6.

The central processing unit 6Ji drives the pages 1 and 2 based on the two pieces of information, and as a result moves the media 12 and pen 3'' to match the drawing starting point intended by the operator.
After drawing r A B CDJ, move the media to the position before the first drawing and wait for the next operator's operation. Here, the unit 4 holds pens of eight or more colors, and by operating a keyboard integrated with the CRT 8, the type of pen attached to the pen/holder can be automatically replaced.

, 75 are diagrams for explaining the relative positional relationship between the coordinate detector and the farm machine, which will be explained below. Fifth
In the figure, the origin (010) of the afiX+Y axis is shown, and b indicates the coordinate origin (0,0) of the coordinate detector. C indicates the plotting start point at the coordinates that the operator desires to plot. a
The difference between the coordinates of * and b is set as Y4 e Xl, and the difference between the coordinates of b and C is set as Yz-Xx. The example rAtBy explained earlier
When drawing with c*DJ, the data reported from the coordinate detection device 7 to the central processing unit 6 is (Yz-X2), and the central processing unit 6 converts the data into ( By commanding the pen to move to the coordinates (Yl + Yz t Xi + Xs), the pen located at the origin t will move to point C.

In addition, the value of coordinate Y1#X1 is fixed data in advance,
It is held in the central processing unit 6.

Also, when the pen is located at coordinate point a', since the relative distance between coordinate points a and a' is held in the central processing unit 6, the coordinate point You can move to C. In fact, it is desirable for the operator to set coordinate point a' on the media because the closer the coordinate points C and a' are, the less time it takes to move.

According to this embodiment, since the operating range of the pen 3' and the operator's operation surface are separated, safety in operation by the operator is improved.

Moreover, since it is a rotational drive system using the belt 11,
The load on the Y-axis drive unit is reduced, the cost of the drive system can be reduced, and the speed of the drive system can be increased. Since the pen 3' operates in a straight line, pen replacement is easy, mechanical vibrations are reduced, and the quality of drawing can be improved.

〔Effect of the invention〕

As is clear from the above-described embodiments, according to the present invention, the range of movement of the pen is separate from the operator's operation surface, so the safety and operability of the drawing machine are greatly improved. Moreover,
Since it is a belt drive system, it has advantages and effects such as the load is significantly reduced, the cost of the drive system can be reduced, high-speed drive is possible, and the quality of drawing can be improved.
