In the sixth embodiment, when a drawing is input from the image input device in the opposite direction to the normal direction due to an operator's mistake, the drawing input management device cannot accurately read the drawing number area of the drawing. Therefore, it is necessary to input the drawing again from the image input device. In the eighth embodiment, even when the drawing is input in the reverse direction, the image data of the drawing is inverted (X-axis and Y-axis coordinate conversion). This eliminates the need to re-enter drawings. Next, the processing of the sixth embodiment will be described with reference to FIGS.
First, step S70 is the same as the processing of the fifth embodiment, and the image data is corrected by the man-machine processing (1) of step S72. Next, the central processing unit 1 (FIG. 1) determines whether or not there is an instruction to invert the image data from the operator (step S72). If the inversion is to be performed (YES), the image data in the drawing is fixed. The data is read from the area 3b of the disk 3 and image data inversion processing of the drawing is performed (steps S73 to S75), and thereafter, the second man-machine processing (2) is performed (step S76).

O), end. In the reversing process, as shown in FIG. 15, first, all the drawing image data (for one sheet) is read (step S74a), and the X and Y coordinates are reversed (step S75b). That is, for the black dot coordinates X (new) after the reversal in the X-axis direction, the paper size X
(Max) is obtained by subtracting the coordinates X (old) of the black dot before the inversion from the image, and calculating the black dot coordinates X after the inversion in the Y-axis direction.
(New) is obtained by subtracting the coordinates X (old) of the black dot before inversion from the paper size Y (max). Next, the image data of the inverted drawing is stored on the fixed disk 3 (step S74c).

FIG. 16 is a flowchart for explaining the processing of the seventh embodiment (Embodiment 7) of the present invention. In the seventh embodiment, if the image data of the drawing that has been input is input once so that the image data of the drawing is not input twice, the “input completed” is performed.
As information and displayed on a CRT device to alert the operator. The processing of the seventh embodiment will be described with reference to the flowchart of FIG. First, step S
The processing of 90 is the same as the processing of steps S50 to S62 of the fifth embodiment. Next, the central processing unit 1 determines whether the drawing of the corresponding drawing number has been registered (step S9).
2) If registered (YES), man-machine processing is performed (step S95), and if not registered (N
O), the image data of the drawing and the fixed position recognition result are stored in the fixed disk 3 (step S93), and the fact that the drawing number has been registered is stored in the fixed position information (step S94). Regarding the man-machine process in step S95, for example, "input completed" may be displayed on the CRT device to alert the operator, or a keyboard or mouse may be locked to disable input data.

[0019]

As described above, according to the first aspect, the four corner points are recognized based on the image data read from the drawing, and the additional information within a predetermined range from the base point is determined based on the four corner points. Since the display area is cut out, the identification number is determined and registered from the image data of the attached information display area, and the image data of the drawing is managed by the identification number, the time required for input processing of the data for managing the drawing is obtained. And shortening of data input errors. According to the second aspect, the result of discriminating the identification number from the clipped accessory information display area is compared with the image data of the identification number in the accessory information display area, and the comparison result is different. Since the identification number can be corrected in this manner, in addition to the effect of the first invention, there is an effect that the correction can be reliably performed when an input error occurs. According to the third aspect, the identification number is determined from the clipped accessory information display area, and the number of digits and the like are checked for the identification number. In addition, there is an effect that it is easy to find an input error. According to the fourth aspect, the four corner points are recognized based on the image data read from the drawing, and the attached information display area of a predetermined range is cut out from the four corner points to a predetermined position based on the four corner points. To determine the range of the attached information display area to be cut out,
The attached information display area can be accurately cut out, and in addition to the effect of the first aspect, there is an effect that the identification number can be more accurately determined. According to the fifth aspect,
While recognizing the four corner points based on the image data read from the drawing, based on the four corner points, a predetermined range of the attached information display area is cut out from the base point,
Since the attached information including the identification number and other information can be read and corrected from the extracted attached information display area, the time required for inputting a lot of data for managing drawings can be reduced, and data entry errors can be reduced. There is an effect that can be reduced. According to the sixth aspect, even when the image data of the above-described drawing is inverted and input due to an error of the operator or the like, it is possible to invert each bit data of the image data and determine the additional information such as the identification number. With this configuration, it is possible to reduce the time required for inputting data for managing drawings, and to further reduce data input errors. According to the seventh aspect, once the image data of the drawing is inputted and registered, the registered information is added to the attached information so that the image data of the same drawing cannot be re-entered. This has the effect of reducing the time required for data input processing for managing data and reducing errors in data re-input.
