Description

TECHNICAL FIELD The present invention relates to an edit area input method, and more particularly to an edit area input method in the case of reducing and copying an original and performing edit processing.

<Prior Art> Conventionally, a copying machine provided with an editing function has been provided as a part of multi-functionalization.

In a copying machine equipped with such an editing function, the conventional method of inputting the editing area is to set the original on a contact glass with the original sandwiched in a dedicated coordinate sheet and handle the area to be edited. To move the pointing piece (see Japanese Patent Application Laid-Open No. 57-16468), and a method of using a tablet to input four points corresponding to the area to be edited by pressing with a pen or the like. (See Japanese Patent Laid-Open No. 57-38065).

In any of the above methods, the area to be edited on the document can be easily input by moving the pointing piece or pressing it with a pen or the like.

<Problems to be Solved by the Invention> In the case of the above method, a dedicated coordinate sheet or tablet is indispensable, and particularly in the case of reducing and copying a large-sized original, the obtained copy is a small-sized copy. Nevertheless, there is a problem in that a large-sized coordinate sheet or tablet must be used. That is, if a reduced copy is made and an edit area is input based on the obtained copy, a dedicated coordinate sheet or a small oval tablet can be used. If you use the tablet or tablet to input the edit area, you can obtain not only the edit processing but also the reduction copy operation for the input edit area based on the once reduced copy. There is a problem that the copy becomes too small.

Also, if the copy magnification is reset to the same size, there will be no problem in terms of size, but since the copy operation is performed based on the copy, the ultimate image quality of the copy will be obtained. There is a problem of decrease.

In addition, if the dedicated coordinate sheet and the tablet become large in size, there is a problem that a large space is required and the cost increases.

Especially when the manuscript is large size such as A3 size,
For the convenience of filing and the like, it is often done to make copies in, for example, A4 size, so that the above-mentioned problems become conspicuous.

<Object of Invention> The present invention has been made in view of the above problems,
The edit area can be set based on the small copy obtained by performing the reduction copy, and the reduction ratio of the copy after the editing process can be set as the reduction ratio set for the original document. It is intended to provide an edit area input method.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the editing area input method of the present invention, in the case of reducing and copying an original larger than a predetermined size and performing the editing process, The original is reduced and copied so that the size of the original becomes a predetermined size, and the coordinate values to be edited based on the reduced and duplicated copy are input. The input coordinate values and the reduction ratio of the reduced copy are input. Based on the above, the coordinate value corresponding to the corresponding area of the original is calculated and set as the editing area.

<Operation> In the editing area input method described above, first, a document larger than a predetermined size is reduced and copied. Then, based on the copy obtained as a result, the coordinate values for performing the edit area are input. Then, the coordinate value corresponding to the corresponding area of the document is calculated based on the input coordinate value and the reduction ratio of the reduced copy. As a result, the edit area of the original is set.

<Examples> Hereinafter, detailed description will be given with reference to the accompanying drawings illustrating examples.
