DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to a first aspect of the present invention is directed to a scanner section for reading an original, a storage section for temporarily storing line data read by the scanner section, A display unit for displaying, and the sender arbitrarily designates and reads the range of the document appearing on the display unit in the sub-scanning direction of the scanner unit. This has the effect that the start and end of the direction can be specified.

According to a second aspect of the present invention, there is provided a scanner section for reading a document, and a mask section movable in the main scanning direction for covering the scanner section from the document surface side. This is characterized in that the original is selectively read and has an effect that the left and right areas of the transmitted original can be limited.

According to a third aspect of the present invention, there is provided a scanner unit for reading a document, an operation unit for restricting data input during reading by the scanner unit, and a bit map of the restricted data among the read data. It has an image data storage unit for forming and storing, and is characterized in that it stores only originals with a limited range, and has the effect of enabling transmission of originals whose areas are partially skipped in the sub-scanning direction. .

An embodiment of the present invention will be described with reference to the following drawings. It is assumed that the sender is familiar with the contents and arrangement of the manuscript in advance, and in general, the manuscript often includes unnecessary parts (hatched parts) as well as unnecessary parts as shown in FIG. First, a description will be given of a method of reading the document while limiting the left and right ranges of the document.

As shown in FIG. 2, a movable mechanical mask section 2 is provided on the right and left of the scanner section 1 so as to cover the scanner section when reading a document. That is, reference numeral 1 denotes a scanner unit for reading a document, and 2 denotes a left and right movable mask unit which covers the scanner unit 1.

The sender adjusts the position of the mask unit 2 so as to remove unnecessary left and right portions, and designates the reading width of the scanner unit 1 in the main scanning direction. In this way, the sender can read the document by limiting the left and right ranges of the document.

Next, a method of selecting and reading an area in the main scanning direction will be described. The pixels of the entire original are temporarily stored in a memory as a storage unit in the facsimile, and then transmitted to a communication partner.

In FIG. 3, reference numeral 3 denotes a partial storage storage unit for temporarily storing data read by the scanner unit 1;
Is a display unit for displaying the data stored in the partial storage unit 3 so that the sender can check it visually. 5 is a unit for sequentially forming and storing the data stored in the partial storage unit 3 as a bit map line by line. An image data storage unit 6 is an operation unit operated by a sender to block data from flowing from the partial storage storage unit 3 to the image data storage unit 5, and a data compression unit 7 is used to compress data before transmission to a communication partner facsimile. Is a compression unit to which data is passed from the image data storage unit 5 for

The line data read by the scanner unit 1 is sequentially read one line at a time for each reading.
Sent to Data for a certain line is stored in the partial storage unit 3, and a part of the transmission document is displayed on the display unit 4.

The sender skips to the operation unit 6 while watching a part of the document displayed on the display unit 4 until the start line which is the uppermost part of the necessary document part appears at the lowermost end of the display unit. Keep inputting the signal. For example, while the sender is pressing the skip button, the original is conveyed, but data during that time is not taken in. FIG. 4 shows an example of a display unit when a document is conveyed.
FIG. 3B illustrates a state at the start of reading, FIG. 4B illustrates a state during reading, and FIG. The state of FIG. 4A shifts from the state of FIG. 4 to the state of FIG. When the data reaches the top, the data is erased.

In the image data storage unit 5, while the skip button of the operation unit 6 is being pressed, no data is formed and the image data storage unit 5 continues to stand by at the top of the image data storage unit 5.

The sender stops pressing the skip button when the start line, which is the uppermost part of the necessary original, appears at the lowermost part of the display unit. Thereafter, the data lines of the document read by the scanner unit 1 are formed in the image data storage unit 5 line by line as an image to be transmitted. FIG. 5 shows an example of an actual arrangement state of the image data storage unit 5. As shown in FIG. 5, the image data is stored in the direction from the top to the bottom of the image data storage unit 5.

Thereafter, while the data is being formed in the image data storage unit 5, the sender checks the part of the original displayed on the display unit 4 while checking the end line which is the lowermost part of the necessary original. Wait for. When the end line appears as shown in FIG. 4C, the user starts to press the skip button of the operation unit 6.

The image data storage section 5 holds the information on the position of the end line, that is, stands by at the next line of the map where the data formation is completed.

When the scanner unit has finished reading the lower end of the document, the loading of the data stored in the image data storage unit ends.

Finally, when the original document size data is formed in the image data storage unit 5, the facsimile notifies the sender of the size in A4, B5, etc., and the sender transmits the original document. Make sure it matches the size of.

If the paper size does not fit within the specified paper size, the fact is notified to the sender. After confirming that the reading of the document from which the unnecessary portion has been removed is completed, the sender instructs the compression unit 7 to send data.

The compression section 7 transmits the fetched data. In the following, an example of skipping a case where the range of the original to be transmitted is divided into two parts by sandwiching unnecessary parts as shown in FIG. As represented by the range 12 and the range 14, the range corresponding to the necessary portion is 2
Suppose you are two areas away. The sender skips the unnecessary portion 11 located above the range 12 and reads the range 12 in the manner described above.

Thereafter, after the end line at the lowermost end of the range 12 is read, the skip button of the operation unit 6 is pressed again to remove unnecessary portions.

While the skip button is pressed, the image data storage unit 5 waits in a state in which data of the range 12 has been formed, that is, in a state in which data is to be formed again from the next line. FIG. 7 shows an example of the image data storage unit.

The sender terminates the reading of unnecessary portions by the scanner unit 1, stops inputting the skip signal when the range 14 of the necessary portion of the document appears on the display unit 4, and causes the scanner unit 1 to read the unnecessary portions. Let it resume.

The image data storage unit 5 forms data of the start line 2 which is the uppermost end of the range 14 from the line line immediately below the end line 1 which is the lowermost end of the range 12.

After reading the range 12 and the range 14 in this way, as shown in FIG. 6B, a document from which unnecessary portions have been removed is transmitted to the destination.

As shown in FIG. 8, every time the scanner reads one line in the chart, the data is shifted upward by one line in the partial accumulation storage unit 3. As a result, FIG.
From the state shown in FIG. 4 to the state shown in FIG.

In this way, the original document arbitrarily designated by the sender in the main scanning direction and the sub scanning direction can be read.
