Abstract

PURPOSE:To easily perform the recording and transmission of a a desired part only, by performing the recording and transmission after changing either a designated part to fetch a data indicated from a vertical and horizontal size designation means or a part other than the designated part, to a white data. CONSTITUTION:When the partial transmission of the desired part X is performed, a coordinate from a reference position is inputted by the size designation key of an operating panel, and a vertical size and a horizontal size (xS, yS) (xE, yE) are designated, and a processor moves an optical device to a designated position (yS) based on a size designation signal, and scans to a designated position (yE), and the picture data of the designated part (yS yE) is transferred to the processor. The processor changes an area other than an area (xS xE) designated by the picture data (yS yE) to the white data. In such way, it is possible to perform the recording and transmission of the desired part easily only by designating the vertical and the horizontal sizes of an original.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to an image reading device such as a facsimile machine that reads, records, or transmits a document using an optical device.

<Prior art> Conventionally, when transmitting and recording images in an image reading device,
Some manuscripts may contain parts that would be difficult to convey to the other party, so it was necessary to edit the manuscript in advance and send it.

<Problems to be Solved by the Invention> Therefore, it is necessary to take time to edit the original before transmitting or recording the original.

The present invention has been made in view of the conventional drawbacks.

To provide an image reading device that eliminates the need to create a document for the image reading device and also eliminates the need for document editing work because the size of a desired portion of the document can be specified.

Means for Solving the Problems> The present invention provides a size specifying means for specifying the vertical and horizontal sizes of a desired portion of the document in an image reading device that reads and stores or transmits a document using an optical device. , a processing device that records or transmits the specified data from the size specifying means by adding white data to either the specified portion of the import or the non-specified portion, and records or transmits only the desired portion. It is characterized by transmission.

<Operation> When performing partial transmission in the image reading apparatus of the present invention, first, the desired size in the vertical and horizontal directions is specified using the size specifying means. Next, the original or the optical device is moved by the processing device so that the optical device is positioned at a desired portion of the original.

The optical device scans only the designated area and transfers the image data to the processing device. The processing device changes the image data to white data except for the designated portion, and records or transmits the white data.

Therefore, by simply specifying the vertical and horizontal sizes of a desired portion of a document, it is possible to easily record and transmit only the desired portion.

<Embodiment> Hereinafter, an image reading device of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of an image reading device according to an embodiment of the present invention, and FIG. 2 is a diagram showing the configuration of the image reading device.

In the figure, 1 indicates the main body of the image reading device, 2 indicates a document holding plate,

It is provided movably in the Y direction). 10 is a processing device that moves the optical device 9 to a specified position and processes a signal sent from the optical device 9 into a desired image, and 11 is a recording device that records the received image. , roll paper 11A.

It is composed of a pinch roller 11B, a platen roller IIC, a thermal head 11D, and a discharge roller LIE.

Fig. 3 shows an operation flowchart of the present invention, and Fig. 4 shows a plan view of the document table, and the operation will be explained according to the figures.

When partially transmitting a desired portion
XE −yE ) is specified, S′5 (nl), and the processing device 10
moves the optical device 9 to the specified position (y5) (B2).

Next, the optical device 9Fi is scanned to the specified position (yE) (B
3) Transfer the image data of the designated portion (y3.yE) to the processing device 10 (B4). The processing device 10 processes the area (XS→XE) specified by the image data (y5→yE).
) to white data (B5), if copying, output it as is to the recording device (B6), and if sending to another device, encode and D/A convert before transmitting (B
7).

This operation ends when it is completed at the specified position (y5)'1.

In the above-described embodiment, size specification was performed by manually inputting coordinates from all reference positions using keys. In this case, as shown in FIG. 4, a tape measure 12 is provided around the original platen 4, and the desired designated fixed area is manually pressed using the coordinates from the reference position A. The present invention does not have to be an image reading device l in which the optical device 9 is moved, but can also be implemented in an image reading device in which the optical device 9 is fixed and the document 7 is moved.

In another embodiment, a slide switch 13 is provided around the document table 4 as shown in FIG. 5, and the desired area X can be specified by moving the slide switch 13.

Furthermore, it is also possible to provide an LED array 14 as shown in FIG. 6 around the original platen 4, and to move and specify the LED display using keys manually.

As shown in FIG. 7, the original 7 is placed on the special sheet 15, and the transmission part X is specified by marking on the sheet 15.
By detecting this marking portion with a detection device (not shown), only the desired portion can be recorded or transmitted.

It is also possible to record several types of designated area patterns (for example, B5° and A4 size), select a designated area pattern manually using a key, and record or transmit only that pattern portion.

Although the embodiment of the present invention is configured so that only the designated area can be recorded or transmitted, it is also possible to make the designated area a prohibited area and record or transmit other than the designated area. .

Furthermore, in other embodiments of the present invention, it is better to use the image reading device 1 that fixes the original and moves the optical device 9 in order to precisely specify the position on the original. However, it is also possible to carry out the implementation even with an image reading device in which the optical device 9 is fixed.

Therefore, with the image reading apparatus of the present invention, it is possible to easily record and transmit a desired portion of a document by simply specifying the vertical and horizontal sizes of the desired portion.

<Effects> As described above, the present invention provides a size specification method for specifying the vertical and horizontal sizes of a desired portion of the document in an image reading device that reads, records, or transmits a document using an optical device. and a processing device that takes in the specified data from the size specifying means, changes either the specified part or the non-designated part to white data, and records or transmits it, and is easy to operate. Only desired parts can be recorded or transmitted ii! ! It is possible to provide an i-elephant reader.
