[Problem to be solved by the invention]

Conventional image reading devices perform image reading operations as described above, so it is necessary to read data in a bound state in which two images are arranged horizontally or vertically, and one image must be enlarged or reduced. If it is necessary to do so, it is of course necessary to enlarge or reduce one image individually and then read it side by side with the other image at the same time, horizontally or vertically, so it is necessary to generate the output image data. There was a problem in that it took time.

This invention was made to solve the above-mentioned problems, and even when reading images of documents of different sizes, it is possible to enlarge or reduce the size as necessary and send out the image data of the image in a bag-bound state. The purpose is to obtain an image reading device.

(Means for Solving the Problems) An image reading device according to the first invention includes an image reading device that optically detects an image, converts a detection signal into image display data, and outputs the image display data; An external interface that outputs data to an image reproduction means, and when displaying a combination of multiple images detected from the same page in a predetermined arrangement relationship,
An enlargement lfi reading instruction means for instructing the enlargement/reduction size of each image as well as the combined display state of a plurality of images; Image data storage means is provided for storing each data in each data storage area in an arrangement determined by the display state and for outputting each data to the external interface according to the image combination state.

Further, the image reading device' according to the second invention includes an image reading means for optically detecting an image, converting a detection signal into image display data and outputting the same, and outputting the image display data to an image reproduction means. an external interface for displaying a plurality of images detected from different sheets of paper in a predetermined layout relationship, an enlargement/reduction reading instruction means for instructing an enlargement/reduction size of each image as well as a combination display state of the plurality of images; After converting each image display data output from the means to the specified enlargement/reduction size, store it in each data storage area in an arrangement determined by the image combination display state, and send each data to the external interface according to the image combination display state. The image data storage device is provided with an output image data storage means.

(Operation) According to the first invention, when document images of different image sizes read from the same paper are converted to the same size and then arranged on the left and right and used as a so-called expansion/contraction bag to create read image data, the same Image data read from the left half of the page is stored as data in the left half of the reading area after scaling, and image data read from the right half is separately stored as data in the right half of the reading area after scaling. The same result as reading a bound image of the same size can be obtained.

Further, according to the second invention, when images of different sizes are read from each original document, the image sizes are converted to the same size, and the images are arranged left and right to create so-called expansion/reduction bag binding read image data, The image data read the first time is stored as data in the left half of the reading area after scaling processing, and the image data read the second time is separately stored as data in the right half of the reading area after scaling processing, so that it looks like two pieces are lined up. The same result as reading a double-bound image can be obtained.

(Example) Hereinafter, an example of the first invention will be described with reference to the drawings.

In Figure 1, (1) is an image reading unit that optically scans and reads an image, (2) is an operating unit that instructs the reading operation, and (3) is an image reading unit that receives instructions from operating unit (2). (5) is an enlargement/reduction bag binding reading instruction unit that instructs left and right separately whether to enlarge, reduce, or read bag binding as it is; (6) is a control unit that controls read image data. An image enlargement/contraction/storage unit (4) is an external interface unit that sends the data of the image enlargement/contraction/storage unit (6) to the outside.

Next, the operation will be explained with reference to FIG. The control unit (3) controls the image reading unit (1) to read the image by operating the operation unit (2) to instruct the start of reading.
At this time, if there is no instruction to read the bag binding in the expansion bag binding reading instruction section (5), the reading range is set to M, for example, the number of main scanning lines in the vertical direction.
Then, MXN bit data is obtained by sequentially scanning in the horizontal direction with the number N of sub-scanning lines from the scanning start point. The read data is sequentially stored in the image enlargement/reduction/storage unit (6).

In addition, when the expansion/retraction bag binding reading instruction section (5) instructs to read the bag binding with no expansion/reduction on the left side and double magnification in both vertical and horizontal directions on the right side, reading the left half will change the reading range in the vertical direction. Scanning is performed sequentially from the scanning start point with the number M of main scanning lines and the number N/2 of sub-scanning lines in the horizontal direction to obtain MXN/2 bit data. This read data is stored in the front half of the image scaling and storage section (6). To read the right half, set the scanning range in the vertical direction with the number of main scanning lines M/2, and in the horizontal direction with the number of sub-scanning lines N/4, and set the scanning start point in the sub-scanning direction with N/4.
The data is scanned sequentially from the point moved by 2, and the read data is enlarged twice in the vertical and horizontal directions in the image enlargement/reduction/storage unit (6) to become MXN/2 bit data, and then the second half is stored. do. Thereafter, all the data stored in the image enlargement/reduction/storage section (6) is sent to the outside through the external interface section (4) according to a predetermined procedure.

In the above embodiment, the left half is read with M main scanning lines and N/2 sub-scanning lines, and the read data is left as is, and the right half is read with M/2 main scanning lines and N/4 sub-scanning lines. Although the case has been described in which the data is enlarged twice in both the main scanning direction and the sub-scanning direction, the enlargement/reduction ratio may be used separately for the left and right sides.

Next, an embodiment of the second invention will be described with reference to the drawing. The configuration of the device is the same as that shown in FIG.

The operation will be described below with reference to FIG. The control unit (3) controls the image reading unit (1) to read the image by operating the operation unit (2) to instruct reading to start, but at this time, the expansion bag binding reading instruction unit (5) indicates that there is no bag binding reading instruction. In this case, the reading range is sequentially scanned, for example, by the number M of main scanning lines in the vertical direction and the number N of sub-scanning lines in the horizontal direction from the scanning start point to obtain MXN bit data. This read cover data is sequentially stored in the image enlargement/reduction/storage unit (6). In addition, when the expansion/retraction bag binding reading instruction section (5) instructs, for example, to read the bag binding with no expansion/reduction on the left side and double magnification both vertically and horizontally on the right side, the first reading will change the reading range in the vertical direction. Scanning is performed sequentially from the scanning start point with the number M of main scanning lines and the number N/2 of sub-scanning lines in the horizontal direction to obtain MXN/2 bit data. This read data is stored in the front half of the image scaling and storage section (6). In the second reading, the reading range is sequentially scanned from the scanning start point by the number of main scanning lines M/2 in the vertical direction and the number N of sub-scanning lines in the horizontal direction, and the read data is used for image enlargement/reduction and storage. In step (6), the data is doubled in both the vertical and horizontal directions to become MXN/2 bit data, and then stored in the second half. Thereafter, all the data stored in the image enlargement/reduction/storage section (6) is sent to the outside through the external interface section (4) according to a predetermined procedure.

In the above embodiment, the left half has the number of main scanning lines M, the number of sub-scanning lines is N/2 and the read data is left as is, and the right half has the number of main scanning lines M/2 and the number of sub-scanning lines N/4. Although the case has been described in which the data after being read is enlarged to 2g in both the main scanning direction and the sub-scanning direction, the enlargement/reduction ratio may be used separately for the left and right sides.

〔Effect of the invention〕

As described above, according to the present invention, a plurality of images are individually read by the image reading means, and after the size of the read image data is expanded/reduced to the same size, it is stored in each image data storage area according to the image combination format. However, since the configuration is such that the contents of all the storage areas are read out on the image display surface and the combined image is displayed, multiple images are combined and edited in advance according to the image combination format, and then the combined image is displayed by the image reading means. This has the effect that combined image data can be easily generated without requiring complicated operations such as reading.
