Abstract

PURPOSE:To select an original picture in a range detected by a marker line detection means and surrounded by a marker line with a transmission or copy means and to send or copy the original picture by drawing a range to be sent or copied partially on an original with 2 marker lines. CONSTITUTION:A part on an original desired to be sent or copied is drawn by two black marker lines. When the 1st maker line is carried to a read position of a CCD 1, a read data is represented in a fully black level, the value of a register K of an MPU 12 is changed from '0' to '1' and the value K is changed from '1' to '2' at the 2nd marker line. When the value K is '1', the data read by the scanning line is coded into the compression code and stored in a memory and when the value K is '2', the read data is all aborted. When the original is scanned up to the tail end, the value K is reset to '0', the data stored in the memory is read and sent or copied.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device capable of transmitting a part of a document image.

Part 1 There is often a request to send only a portion of a document using a facsimile machine.

Conventional facsimile machines cannot meet such requests unless they physically cut out a portion of the original to be sent, which is very inconvenient.

An object of the present invention is to provide an extremely convenient facsimile device that can transmit image information within a specified range by simply specifying an area with a marker on the transmission document (without cutting out the transmission document). There is.

In order to achieve the above-mentioned purpose of "1", there is provided a marker line detecting means for detecting a marker line marked on a transmission document in a direction intersecting the sub-scanning direction, and a marker line detecting means for detecting a marker line marked on a transmission document in a direction crossing the sub-scanning direction. The present invention is characterized in that it includes means for transmitting or copying the original image from the time when the second marker line is detected to the time when the second marker line is detected.

According to the present invention, by marking the range to be partially copied or partially transmitted on a document with two marker lines, the marker line detection means detects the first and second marker lines. , a partial transmission or copying means selects and transmits or copies the original image within the range surrounded by the two marker lines.

Figure 1 shows a block diagram of a facsimile machine for carrying out the method of the present invention, in which numeral 1 is a CCD array for reading a transmitted document line by line, for example. A sheet of paper with characters drawn on it as shown in FIG. 3 is used as the transmission document. When only part of the original is to be sent, two markers M+ 2Mz are placed on the original to specify the part P to be sent.
It is delineated by

Note that the color of the marker does not matter, but the thickness must be sufficiently thicker than the characters on the document; for example, a thick black marker pen is suitable.

2 is an image processing circuit that binarizes the image data read by the CCD 1; 3 is a RAM that stores a program for executing the sending operation of the facsimile machine.

A storage circuit including a ROM, 4 a circuit for encoding necessary to transmit image data, and 5 modulating transmission data and sending it out to a telephone line, or demodulating received data input from a telephone line. A modem, 6 is an operation key including a numeric keypad, a start key, a partial send key, a partial copy key, etc. provided on the outer panel (not shown) of the facsimile, 7 is a keyboard controller, and 8 is an LCD display provided on the panel. 9 is an LCD controller, 10 is a thermal head for recording data received through a telephone line on recording paper, 11 is a circuit for driving the head 10, and 12 is connected to the above circuit through a data bus DB for transmitting and receiving operations. It is a microprocessor that controls the

The facsimile machine with the above configuration can perform sending, receiving, and copying functions using the same operations as conventional ones. That is, after setting the original on the original table (not shown) and entering the recipient's phone number,
When the start key is pressed, the original is read and sent, and when the copy button is pressed without pressing the destination phone number and the start key, the original can be copied. Also, if a call is received through the telephone line, after exchanging transmission control signals,
Perform automatic reception.

On the other hand, if the document to be set on the document table has markers &iM,,M, as shown in FIG. 3, and the partial transmission key or partial copy key is pressed, the flowchart shown in FIG. Execute processing. That is, when any of the above keys is pressed (Sl), MPUI 2
The register K inside is set to 0 (S2). This register is used to determine whether the current document scanning position is in the range surrounded by marker line M+9M2. If K is O, it is determined that the current document scanning position is in the range before the first marker line M1. If K is 1, it means that the document scanning position is between the first marker line M and the second marker line M2,
Furthermore, if K is 2, the document reading position is the second marker line M.
2 to the rear edge of the document. Also, it is expected that three or more marker lines will be mistakenly drawn on a single document, and in that case, K will take a value larger than 3, but as will be explained later, in this case, K will be the same as 2. will be processed.

The direction in which the document is conveyed (sub-scanning direction) in the reading section is the direction indicated by arrow A in FIG. 3, and therefore, the reading start position is at the upper end of the document. When the partial copy key or the partial send key is pressed, the upper end of this document is automatically conveyed to a CCD reading position by a scanner motor (not shown) and stopped at that position.

After completing the processing in step S2, the program moves from S3 to 8.
Proceeding to step 4, the COD scans and reads one line of the upper edge of the document. Then, the read data for one line is quantized, sampled, encoded, and further subjected to band compression processing (S
5). The compressed code for one line thus obtained is judged in step s6 whether it is an all-black code.

An all-black code means that all pixels are black over the entire length of one scanning line, and such an all-black code does not exist on a document except when scanning marker lines M+ and M2. If the compressed code of the read data is not an all-black code, the process advances to step S8, and it is determined whether the value of K is 1 or not.

Step S when you press the partial copy key or partial send key
2, K is set to 0, and the value of K is maintained at O until the first marker line is scanned. In that case, the process advances to step S9, and the compressed code of the line read earlier is discarded. Next, the scanner motor is rotated by one line to feed the document one line in the sub-scanning direction A (SIO), and the next line is read. Thereafter, this operation is repeated until the first marker line is detected, and all read data is discarded.

Next, when the first marker line is conveyed to the reading position of the CCD, the read data of that part is all black and its compressed code is an all black code, so the program proceeds from step S6 to S7. Add 1 to the value of K. Since the value of K was O until this time, K becomes 1 when the process proceeds to step S7. Then, the program goes from S8 to Sl.
The process advances to step 1, and the data read earlier (in this case, the all-black code) is stored in the memory. Next, turn the scanner motor 1
Move by one line and read the next line. In addition,
As mentioned above, since the marker lines Mt and Mt are thick, the all-black code is actually detected across multiple lines, so when the first marker line M is scanned, K is 5 or 6. It is expected that the value will be . However, in that case, it can be handled by setting the value of K in step S8 to 5 or 6. However, for convenience of explanation, in this embodiment, =1 is the value from when the first marker line M1 is detected to when the second marker line M2 is detected.

Since the time between detecting the first marker line M and detecting the second marker line M2 is 1, the data read in each scanning line during that time is encoded into a compressed code and stored in memory. be done. Then, when the CCD starts scanning the second marker line M2, the data read at that time is an all-black code, so the program moves to step S6.
Proceed to 87 and change K to 2. The program then proceeds to 58-39-310 and discards the read data. Thereafter, this operation is repeated until the rear end of the document is scanned, and all read data is discarded without being stored in the memory.

Note that three or more marker lines may be mistakenly drawn on the manuscript, but in that case, the value of K is the same as the number of marker lines.
This will increase to 3.4...

However, if the value of K is other than 1, the program proceeds to step S8-39→SIO and steps S11. Since S12 is not passed, there is no possibility that unnecessary portions will be stored in the memory.

After scanning to the rear edge of the document as described above, the program advances from S3 to S13, resets K to 0, and determines whether the key pressed in step S1 is the copy key or the send key. A judgment is made (S14). If it is a transmission key, the read data is sent to the line through the modem (515), and if it is a copy key, after decoding the read data (S16), the thermal head of the receiving section is driven to transfer it to the recording paper. Print the read data (S17
).

Note that the marker lines M, M2 are usually drawn by the operator's hands, so they are drawn completely parallel to the main scanning direction.

It is difficult to follow, and it is somewhat oblique. In this case, if the marker line is thin, reading and scanning on the marker line may not result in all black data, so even if the marker line is a little skewed, all black data will always be obtained when reading on the marker line. It is desirable to use a sufficiently thick marker.

As explained above, according to the present invention, by simply specifying the range to be sent or copied with a marker on the original, it is possible to select and send or copy the original image within that range. It is very easy to use as there is no need to cut out parts of the document as in
