22 the paper format of the drawing and thus the format of the

23 plotters, the cost of a plotter varies.

24 A plotter for the character format DIN A 0 currently costs

25 at least DM 40,000.00. This plotter comes at a cost

26 nor the cost of the computer itself with its software,

27 of the storage facilities, as well as the costs, if applicable

28 of a so-called graphics or digitizing tablet.

31 only the workplace for a single draftsman,

32 although the actual computer in larger computers

33 and larger storage facilities - at higher costs

34 of the same - can also be used for several workplaces

35 can. Smaller companies can therefore usually do this

36 such systems for DIN A 0 formats cannot provide.

However, 3 systems cannot process DIN A 0 sheet formats

4, only one sheet can be used in the plotter

5 of the DIN A3 format can be inserted.

6 There are now plotters, although they only have one

8 larger drawing sheet can be placed and there

9 can be moved. These plotters have a

10 Input keyboard on, can be moved with dsr dsr drawing pen

11 can. These plotters are relatively inexpensive, and they can

12 with the corresponding user software also by means of so-called

13 named micro- or personal computers, which are already in many

14 writing and drawing offices are available

Become 15. Using this plotter, various individual

16 drawings of the maximum format DIN A 3 on one

17 larger sheets can be drawn. The plotter will open

18 this larger drawing sheet moved by hand and

19 aligned. But it is not in this way of working

20 possible to draw a figure larger than that

21 DIN A 3 format to be processed by the plotter.

22 Such a well-known plotter is e.g. from the company

23 Rotring Technik GmbH under the name "NC-plotseriber"

24 expelled. There are various control units and

25 also a CAD system (screen drawing creation

26 system). This system is also very expensive.

27 The invention is based on the object / a generic

28 to create a proper drawing board with the drawings

29 of the DIN A 0 format can be created more cheaply.

30 This task is defined by the subject matter of the claim

31 1 solved. The total area of the drawing board is in

32 divided into several fields that at least touch each other

33 or even slightly overlap with those of the plotter

34 can be permanently assigned.

35 An essential element of the invention is a

36 plotter, which is opposite to a drawing board in different

37 who can determine exactly definable positions.

38 This plotter does not have its own support surface for

4 bottom, i.e. it has an open bottom

5 frames. Such a plotter essentially consists of

6 a rectangular frame in which in one to one

7 pairs of side edges parallel direction a guide

9 lies across these side edges. On this guide rail

11 movable and perpendicular to the plane of extent of the frame

12 can be raised and lowered. A plotter with one down

13 open frame is known as such (see "NC plotscri-

14 about "from Rotring Technik GmbH).

15 The plotter now used here, however, still needs resources

16 for permanent assignment to a specific and determinable

17 field of the drawing board, i.e. the plotter may

19 can be moved completely freely. These means allow

20 dun plotter exactly to the individual fields

21 judge and keep. Such means can be found on the drawing board

22 fixed pins that engage in holes

23, which can be carried out either directly on the plotter or on inem

24 component firmly connected to the plotter are provided. (! 25 You can also use the drawing board as well as the

26 plotter bores may be provided which are aligned

27 and through which to lock the plotter opposite

28 the drawing board pens or the like. are slidable.

29 Such a plotter preferably also has a

30 Keypad, via which control commands for the character (s)

31 pen (s) can be entered.

32 Further details and advantages of the invention

33 result from the subclaims and from below

34 exemplary embodiments described with reference to the drawing.

35 It shows:

'4 Figure 3 is a plan view of a drawing board with a

5 plotter according to a third embodiment, and

6 Figure 4 is a plan view of a drawing board with a

7 plotter according to a fourth embodiment.

8 A drawing board 1, which is known as such

9 and also have a drawing machine, not shown in can>. dis yegklappbar cdsr vjssschwsrtkbsr is, bssitzt hisr 11 at least one horizontal at its upper longitudinal edge

, 12 arranged row of pins 2, which are identical to one another

■ 13 are moderately spaced and their axes are perpendicular to the

. 14 extend plane of the drawing board 1.

15 This drawing board 1 is according to Figure 1 for maximum

16 sheet formats DIN A 0 (1,189 mm χ 841 mm) are provided, and

17 has a width of 1.5 m and a height of 1 m. on

18 of this drawing board 1 is a drawing sheet 3 of the

19 formats DIN A 0 arranged. This drawing sheet 3 is now

20 divided into three times three matrix fields 4 what through here

21 dash-dotted field delimitation lines 5 is indicated.

22 According to Figure 2, the drawing board 1 for drawing formats

23rd DIN A1 (841 mm χ 594 mm) provided and accordingly

24 smaller. On this drawing board a) 25 drawing sheet DIN A1 is arranged, which is analogous to Figure 1

26 is divided into two two matrix fields 4.

27 This division into matrix fields 4 needs on the

28 drawing sheet 3 not to be made by lines,

29 although such auxiliary lines make it easier to get over the top.

30 Each of these nine or four matrix fields 4 can have one

31 and the same plotter 6 are assigned, so that for this

32 a plotter 6 nine or four different arrangements

33 must be possible. Each matrix field 4 is assigned

34 moderately - here - two-digit field number 7, e.g. 11, 12,

35 13, 21, 22, 23, 31, 32 and 33 or 11, 12, 21 and 22, where

36 the first digit indicates e.g. the "line" of the matrix,

37 while the second digit denotes the "column" of the matrix

2 The plotter 6 can only have one matrix field in the

3 Edit size DIN A 3. Due to the exact assignment of the

4 Plotters 6, which will be discussed in more detail below, too

5 a certain matrix field 4, e.g. in Figure 1 to the

6 Matrix field 4 with the field number "23" and in Figure 2 to the

7 matrix pad 4 with the box number "22", the computer can

8 internally a whole drawing sheet of size DIN A 0 resp.

9 DIN A 1 manage and it can be done through successive

10 Displacement of the plotter 6 over the entire sheet form

11 mat are drawn if the computer is given the, 12 field number 7 of the matrix field 4 to which the

13 plotter 6 is assigned in each case. This is through a

14 software program possible, which due to the assignment

15 of the specific matrix field 4 from the virtual total

16 image of the memory of the computer only the respective

17 selects virtual image of the specific matrix field 4.

18 The assignment of plotter 6 to a specific one

19 Matrix-Fald 4 can due to two similar trainings

20 of the drawing board can be obtained, the execution

21 form according to Figure 2 is only possible if the entire sheet in

22 is divided into two fields 4 a maximum of twice, i.e. if

23 e.g. when using a DIN A3 plotter only one

24 is to be created drawing in DIN A 1 on a correspondingly smaller (25 ren drawing board. 1

26 as stated above, Figure 1 shows the use of a

27 DIN A 3 plotters 6 for creating a DIN A O drawing

28 tion, whereby a matrix with nine fields 4 is necessary.

29 Since the Ratrix field 4 with the field number "22" does not have a

30 Side edge with the character format of the sheet in format

31 DIN A 0 has in common, so the plotter 6 does not - as in

32 Figure 2 - set immediately next to the drawing sheet

33, there is a plate 8 on such a plotter 6

34 attached, which should be as transparent as possible and here

35 consists of a plexiglass.

36 This plate 8 is here a little narrower than the largest

37 length of plotter 6 while the length of plate 8- in

38 Figure 1 seen in the vertical, so in the direction of the

1 shorter side edge of the matrix area 4 - slightly

2 greater than twice the length of the shorter side edge of the

3 matrix field 4 is.

4 This plate 8 now points here, i.e. for a

5 character format DIN A 0 and a plotter of the format

6 DIN A 3, three vertical rows of evenly spaced apart

7 spaced holes 9, the three rows

8 are evenly spaced from one another. The distance

9 between every two rows of holes 9 is a maximum, so

10 large, like the shorter side edge of a matrix field 4

11 is long. Corresponds to the size of the matrix field 4 exactly

12 the format DIN A 3, i.e. 420 mm χ 297 mm, this is ^ 13 Distance e.g. 280 mm.

14 The distance between the holes 9 of a row is

15 so that a multiple of it is a maximum of the length

16 corresponds to the longer side edge of the matrix field, at

17 DIN A 3 format, e.g. the distance between two

18 holes is 140 mm.

19 According to the embodiment of Figure 1 is now on

20 upper side edge of the drawing board 1 a bar 10

21 attached, in which the pins 2 are arranged in a row

22, this row being parallel to this side edge of the

23 board runs. The distance between two neighboring ones

24 pins 2 corresponds exactly to the distance between adjacent ζ 25 holes in plate 8.

According to FIG. 1, three pins 2 each grip the bar

27 10 in three holes 9 in a row. This gives the

28 plotter 6 opposite one on the drawing board

29 drawing sheet 3 an exactly defined position, according to

30 Figure 1, the field number "23" is to be assigned.

31 Now detach plate 8 from pins 2 and

32 moves it together with the plotter 6 by three pens here

33 to the left, the plotter 6 of another is exactly

34 defined position, here the matrix field 4 with the

35 Assigned to field number "22". This matrix field 4 now has

36 coordinates in virtual image of the computer around the

37 three times the distance between adjacent pins 2, so here around

13 be. It is only essential that the computer has the

14 exact position of plotter 6 by F, input z.O. the

15 field number 7 is communicated.

16 The plotter 6 now has a keypad 12. With

17 this keypad 12 can control commands for the character

18 pen can be entered into plotter 6. Depending on the command,

19 this command is also sent directly to the computer via the

20 line 13 communicated via the keypad 12 can

21 e.g. enter that the drawing pen is based on a

22 pre-determined point a line in a certain

23 should pull in the direction and with a certain length.

24 The designer who used this drawing board 1 with (*) 25 plotter operated, no longer draws with pencil and

26 ruler, but it gives e.g. the angle via the keypad

27 one that he previously set on his drawing machine,

28 whereupon he then enters via the keys on the keypad 12,

29 how long the line should be that the pen draws

30 should. If he does not know the exact length of this line, then it can

31 he himself, as before with his pencil, at the end of it

32 "feel up", i.e. it first gives a large character

33 step and then smaller and smaller drawing steps over the

34 keypad until the line ends where it appears according to the

35 Presentation of the designer should end. So it is

36 not necessary, first the exact end coordinates of a
