Abstract

An image-scanning apparatus for inputting image data to an image processing device. The apparatus includes an image document holding cassette for holding an image document, a document holder stacker for storing the image document holding cassettes therein, and supplying the image document holding cassette into a scanner, the scanner for irradiating the image document located on a document supporting table and inputting the image data from the irradiated image document with an input sensor through a magnification mechanism, the magnification mechanism for changing the magnification of the image document at said input sensor so that the magnification of the image data is changed, and the document supporting table being capable of changing the angle of the image document to the scanner so that the angle of the image data is changed.

Claims

1. An image scanning apparatus for inputting image data representing a plurality of documents to an image processing means, comprising:

a plurality of image document holding means for holding a plurality of corresponding image documents;

a document holder storing means for storing said plurality of image document holding means therein, and individually transferring each of said image document holding means to a scanning means;

said scanning means for irradiating an image document located on a document supporting means, and inputting said image data from said irradiated image document with an input means through a magnification means;

said magnification means for changing the magnification of said image document located on the document supporting means at said input means so that the magnification of said image data is changed; and

said document supporting means being capable of changing the angle of said image document located on the document supporting means relative to said scanning means so that the angle of said image data is changed.

2. The apparatus claimed in claim 1, wherein each of said image document holding means has an identification code mark provided thereon so that each image document holding means and the image document held therein is identified by said image processing means.

3. The apparatus claimed in claim 2, wherein said input means inputs said image data line by line.

4. The apparatus claimed in claim 3, wherein said image documents are transparent.

5. An apparatus for providing image data representing a plurality of documents to an image processor, comprising:

a plurality of means for holding the documents, each holding means holding a corresponding document;

means for individually irradiating each of said documents to produce images representing said documents;

means for supporting at least one of said plurality of holding means, said supporting means being capable of changing the angle of a document held by said one holding means relative to said irradiating means to change the angular orientation of an image representing the document held by said one holding means;

means for storing said plurality of holding means;

means for individually transferring each of said holding means from said storing means to said supporting means;

means for adjustably magnifying said image representing the document held by said one holding means; and

means for generating image data in response to said image representing the document held by said one holding means and providing said image data to said image processor.

6. The apparatus claimed in claim 5, wherein each of said plurality of holding means has an identification code mark provided between thereon so that the image processor is capable of identifying each holding means and the document held therein.

7. The apparatus claimed in claim 5, wherein said generating and providing means transmits said image data line by line.

8. The apparatus claimed in claim 5, wherein said documents are transparent.

9. A method for providing image data representing a plurality of documents to an image processor, comprising the steps of:

providing said documents in a document holder storing means which is capable of storing said plurality of documents;

generating image data for each of said plurality of documents, the step of generating the image data including the steps of;

(a) individually conveying said documents from said document holder storing means to an irradiating position; and

(b) individually irradiating said documents at said irradiating position with a first scanning means to form images representing said documents;

providing said image data to said image processor and displaying the image data on a display means;

deriving angle data and magnification data for said images;

altering the angular orientations and the sizes of said images in accordance with said angle data and said magnification data, respectively;

generating altered image data in response to said altered images; and

providing the altered image data to said image processor.

10. The method according to claim 9, wherein said step of generating altered image data includes the steps of:

individually conveying said documents from said document holder storing means to a second irradiating position;

positioning said documents at said second irradiating position in order to obtain the altered angular orientations and sizes of said images, and

individually irradiating said documents with a second scanning means to form said altered images representing said documents.

11. The method according to claim 9, wherein said step of deriving angle data and magnification data includes the steps of:

providing framing data to said image processor and displaying the framing data on the display means;

identifying a plurality of image points on said displayed image data;

identifying a plurality of frame points on said displayed framing data; and

determining the changes in the angular orientations and the sizes of the images which are necessary to provide altered image data such that the plurality of image points on the altered image data correspond to the plurality of frame points on the displayed framing data.

12. The method according to claim 9, wherein said step of deriving angle data and magnification data includes the steps of:

identifying a plurality of instruction points on instruction images placed on a dimension input means connected to said image processor;

identifying a plurality of image points on said displayed image data; and

determining the changes in the angular orientations and the sizes of the images which are necessary to provide altered image data such that the plurality of image points on the altered image data correspond to the plurality of instruction points on the instruction images.

13. The method according to claim 9, wherein said step of generating altered image data is performed after image data has been generated for all of said plurality of documents.

14. A method for providing image data representing a plurality of documents to an image processor, comprising the steps of:

providing said documents in a document holder storing means which is capable of storing said plurality of documents;

generating image data for each of said plurality of documents, the step of generating image data including the steps of;

(a) individually conveying said documents from said document holder storing means to an irradiating position;

(b) individually irradiating said documents at said irradiating position with a first scanning means to form images representing said documents; and

(c) storing first angle data and first magnification data for each of said documents at said irradiating step in a memory means;

providing said image data to said image processor and displaying the image data on a display means;

correlatively deriving second angle data and second magnification data for each of said images in relation to said first angle data and said first magnification data;

altering the angular orientations and the sizes of said images in accordance with said first angle data and said second angle data, and said first magnification data and said second magnification data, respectively;

generating altered image data in response to said altered images; and

providing the altered image data to said image processor.

15. The method according to claim 14, wherein said step of generating altered image data includes the steps of:

individually conveying said documents from said document holder storing means to a second irradiating position;

positioning said documents at said second irradiating position in order to obtain the altered angular orientations and sizes of said images, and
