When it is returned and the document is the final document, the basic operation is finished (step 111).

Next, the operation of the cut and edit process in step 3 of FIG. 6 will be described.

In the case of this embodiment, since the input pen 39 is in the shape of a marker pen having a certain width as shown in FIG. 4, as shown in FIG. In the case of a portion having a high image density such as a character string, it is convenient because the input pen 39 may be moved by touching it once in the direction of the arrow B in a manner of marking the area 51.

Hereinafter, with reference to the flowchart of FIG.
The cutting process will be described.

First, in step 201, in order to designate the cut-out designation area 51 shown in FIG. 7, the input portion 43 of the pen tip 41 of the input pen 39 as shown in FIG. 4 is moved to the designated area on the sense line 31 of the digitizer 37. It is placed at the left end 53 of 51. Next, in step 203, the predetermined position 47 of the input part 43 of the placed pen tip 41 is recognized by the sense line 31, and in step 204, the arithmetic processing part 40 causes the rectangular designating area of the input part 43. The coordinate value of is calculated based on the positional relationship information between the predetermined position 47 and the outer periphery of the rectangular input section which is held in advance. That is, if the input portion of the pen tip is a rectangle, the coordinate values of a plurality of points indicating the rectangle, for example, the coordinate values of the four vertices of the rectangle and the coordinate values of two diagonal points are calculated. Next, at step 205, the input pen 39 is moved to B in FIG.
Then, the coordinate values of the designated area 51 are sequentially calculated, and the recognized cut designated area 51 is clarified on the display. That is, since the portion traced by the input pen 39 is directly selected as the cut-out designated area, the selected designated area is already selected at each time point as shown in FIG. 9 so that the user can sequentially recognize it. The designated area is highlighted on the display board 5 in black and white for clarity. Then, with respect to the region which has been inverted once, the inverted display is continued as it is even if the designation process is performed again. In the reverse display, the CPU 29 subtracts the actual brightness (density) from the maximum brightness (density) given to each pixel of the specified area based on the coordinate value of the cut-out specified area from the pointing device 7. This is accomplished by determining the value and displaying it. Next, step 20
In step 6, it is judged whether or not the designation process of the desired cut designation region 51 is completed. If the designation process is not completed, the movement of the input pen 39 is further continued in step 207, and the process goes to step 203. Return. If it is determined in step 206 that the designation process has been completed, then in step 208, the determination process for all designated regions is performed. That is, in step 204,

This coordinate value may be determined by calculating a plurality of coordinate values by calculating the coordinates of each recognized small figure area, or as shown in FIG. This may be performed by turning on the selection bit inside the small figure and synthesizing it. Then, finally, in step 209, the obtained images of all the designated areas are stored in the second memory 2 for the output image.
3 is written in the output area 25 of the display board 5, and the cutting process is completed.

Next, a second embodiment of the layout copier according to the present invention will be described with reference to FIG.

The second embodiment is the same as the pointing device of the first embodiment, except that the marker pen-shaped first input pen 39 having a certain width as described above and the second input pen for designating one point. In the case of an image in which the cutout region 63 exists as shown in FIG. 12 apart from other image portions and the cutout boundary is slightly errored as shown in FIG. Using the second input pen 61, the cutout area 63 is surrounded by a plurality of dot sequences as in the conventional case, and the designation processing is performed.
In the case of an image having a high image density as shown in FIG. 7, the designation processing as described above is performed using the first input pen 39. The rest of the configuration operation is the same as that of the first embodiment, so a detailed description will be omitted.

In the above embodiment, the coordinate values of the four vertices of the rectangle are calculated in order to obtain the coordinate values of the rectangular designated area after recognizing the predetermined position 47 of the input section 43 of the marker pen-shaped input pen 39. The coordinate values of the two-diagonal points are calculated, but as shown in FIG. 13, the information of the pen tip graphic is stored as a bitmap image, and the determined predetermined position 47 and the pen tip graphic The designated area may be determined by superimposing it on the predetermined position 71 in the bitmap image of.

Further, as the clarification processing of the cut-designated area, a certain pattern may be superimposed and displayed on the designated area in addition to the inversion processing.

Further, although an electromagnetic type digitizer is used as the digitizer of the pointing device in this embodiment, it is possible to recognize the coordinates of the position designated by the input pen of the pressure sensitive system and the display is the sense line. Anything that can be repeated can be used.
