Electrophotographic copying apparatus with an editing mode

A copying apparatus having a usual mode wherein a document image is copies in its entirety onto copy paper and an edition mode wherein a desired portion of the document image is copied onto copy paper, the copying apparatus comprising:

• image forming means capable of copying the document image in the usual mode and the edition mode,
• coordinate initial value memory means for storing area data specifying a specific area of the document, coordinate memory means for storing area data specifying a specific area of the document for use in controlling the copying operation of the apparatus in the edition mode,
• means for selecting the edition mode,
• means responsive to the selection of the edition mode for transferring the data stored in the coordiante initial value memory means to the coordinate memory means and storing the data therein,
• key input means, and
• means responsive to the manipulation of the key input means for varying the data stored in the coordiante memory means.

A copying apparatus adapted to specify a desired portion of a document by at least two coordinate data items and to copy the specified portion on copy paper, the apparatus comprising:

• first coordinate memory means for storing first data included in the area data for use in controlling copying operation in an edition mode,
• second coordinate memory means for storing second data included in the area data for use in controlling the copying operation in the edition mode,
• means for feeding specific coordinate data to the first coordinate memory means,
• first varying means for varying the data stored in the first coordinate memory means and causing the first coordinate memory means to store the varied data again,
• means for causing the second coordinate memory means to store the data stored in the first coordinate memory means,
• second varying means for varying the data stored in the second coordinate memory means and causing the second coordinate memory means to store the varied data again, and
• means for copying on copy paper the document portion specified by the data stored in the first and second coordinate memory means.

• data variation command input means,
• mode selection means for selecting one of a first coordinate selection mode and a second coordinate selection mode,
• first varying means responsive to a data variation command in the first coordinate selection mode for varying the data stored in the first coordinate memory means and causing the first coordinate memory means to store the varied data again,
• means for causing the second coordinate memory means to store the data stored in the first coordinate memory means when the second coordinate selection mode is selected,
• second varying means responsive to a data variation command in the second coordinate selection mode for varying the data stored in the second coordinate memory means and causing the second coordinate memory means to store the varied data again, and
• means for copying on copy paper the document portion specified by the data stored in the first and second coordinate memory means.
