As will be described later, the device of this embodiment displays image information drawn within a partial area on the screen of the display tube 5 specified by the user.
This is to be output to the hard copy device 7. The operation of the device of this embodiment will be explained below according to the user's operating procedure.

First, the user uses the cursor movement key 15 to indicate to the hard copy device 7 the area to be output.

The instruction is made, for example, by specifying the upper left end and lower right end of the area to be output. First, move the cursor to the upper left corner of the area you want to output. After moving, turn on the upper left end coordinate input switch 18. Based on this signal, the cursor position detection device 14 sends the coordinates of the upper left end to the two-dimensional map creation device 12.

Next, move the cursor to the bottom right corner of the area you want to output,
Turn on the lower right coordinate input switch 19.

In response to this signal, the cursor position detection device 14 sends the coordinates of the lower right end to the two-dimensional map creation device 12.

Based on the received upper left coordinates and lower right coordinates, the two-dimensional map creation device 12 creates a 1-0 matrix map with 11" in the designated area and 0" in the other areas, as shown in FIG. M is sent to the two-dimensional map storage memory 13. In FIG. 3, the number of bits in the horizontal direction of the matrix map M corresponds to the number of dots in the horizontal direction of the display screen, and the number of bits in the vertical direction corresponds to the number of dots in the vertical direction of the display screen. Also,
A is the upper left coordinate, and B is the lower right coordinate.

According to the AND circuit 21, the two-dimensional map storage memory 1
The contents of image information storage memo 1711A are ANDed with the contents of image information storage memo 1711A, and the result is stored in image information storage memory IIB. Through this process, image information storage memo 1, 111
In B, the drawing information in the area specified by the user is set to “1”,
A 1-o matrix map with other values set to "0" is registered. The contents of the image information storage memory 11B are output to the hard copy device 7 via the image information output control device 6 by turning on the information transmission switch 2o.Hard copy device 7

25 is an enlarged/reduced image information creation device; 26 is an enlarged/reduced image information creation device; 26 is an enlarged/reduced image information creation device; Further, 28A and 28B are readout circuits, 29A and 29B are latch circuits, and 30 is a switch.

The device of this embodiment receives the image information of a partial area of the display screen created by the processing described above from the image information output control device 6, and enlarges it to the restored size on the copy paper specified by the user. Alternatively, it can be reduced and output as a hard copy.

The operation of the device of this embodiment will be explained below according to the user's operating procedure. It is assumed that the image information of the partial area of the display screen has been registered in the image information storage memory 22 in advance.

First, the user changes the magnification/reduction ratio (restored figure size on copy paper/figure size on display screen).
Set using the reduction magnification designation dial 23. The dial value detection device 24 detects the magnification set on the dial 23 and sends it to the enlargement/reduction matrix creation device 25.

The enlargement/reduction matrix creation device 25 creates an enlargement/reduction matrix [X] based on the sent magnification using the following equation.

[X]=α[Y] Here, α is a magnification, and [Y] is a matrix indicating dots on the display screen. The creation result is stored in the enlargement/reduction matrix storage memory 26. When the user turns on the copy output switch 30, the previously registered image 1
The contents of the image information storage memory 22 and the contents of the enlargement/reduction matrix storage memory 26 are sent to the enlarged/reduced image 1 image information creation device 27. The enlarged/reduced image information creation device 27 processes the following steps to create enlarged/reduced screen information and outputs it to the hard copy device 7.

Note that FIG. 5 shows a specific example of the operation corresponding to the following steps, taking as an example the case where the screen is reduced.

Step 1; Contents of the image information storage memory 22 (Fig. 5C
) and the contents of the enlargement/reduction matrix storage memory 26 (FIG. 5D).

Step 2: Superimpose the above two pieces of imported information as shown in Figure 5E.

Step 3: As a result of overlapping, within the square opening of the enlargement/reduction matrix, the squares with a value equal to or greater than the ratio of the area of the shaded area and the area of the white (non-hatched) area are defined as the shaded area, and the others are defined as the white area. A matrix (Fig. 5F) is created.

Step 4: Overlay the matrix created in step 3 with the matrix indicating the size of the paper to be output (Fig. 5G).

Although FIG. 5 shows the case of reduction, the same applies to the case of enlargement.
