Abstract

PURPOSE:To transmit or copy picture information in a designated range even when plural spots are designated by providing a selecting means to select an area surrounded by an odd-number-th maker line and an even-number-th marker line larger than the above mentioned line only by 1. CONSTITUTION:On an original, the range to be partially copied or partially transmitted is described by marker lines M1-M4. A marker line detecting means detects these marker lines M1-M4 and based on a detected result, the selecting means selects the area surrounded by the odd-number-th marker line and the even-number-th marker line larger than the above mentioned line only by 1. According to the result of this selection, an output means reads and transmits or copies the pictures in the range to the odd-number-th marker line and the even-number-th marker line larger than the above mentioned line only by 1. Thus, even when the plural ranges are designated, the original pictures of all the ranges can be selected and transmitted or copied and it is not necessary to partially cut off the original.

Description

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

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

2. Conventional facsimile machines cannot meet such a request unless a part of the transmitted document is physically cut out, which is very inconvenient.

Furthermore, depending on the manuscript, there are cases where it is desired to copy or transmit two or three parts of the manuscript, which is even more inconvenient.

The present invention does not require cutting out the original to be sent, but by simply specifying an area with a marker on the original to be sent, image information within the specified range can be sent or copied, regardless of whether it is two or three areas. The purpose is to provide an extremely convenient facsimile machine that can perform

In order to achieve the above-mentioned purpose of i ″゜, there is provided a marker line detecting means for detecting marker lines written in a direction intersecting the sub-scanning direction on a transmitted document, and a marker line detecting means for detecting marker lines written on a transmitted document in a direction intersecting with the sub-scanning direction, The present invention is characterized by comprising a sorting means for sorting out areas surrounded by large even-numbered marker lines, and an output means for reading and transmitting or copying the document image of the area sorted by the sorting means.

According to the present invention, by marking the range to be partially copied or partially transmitted on a document with a marker line, the marker line detecting means detects the marker line, and the detection result is detected by the marker line detecting means. Based on this, the selection means selects an area surrounded by an odd-numbered marker line and an even-numbered marker line that is 1 larger than the odd-numbered marker line.

Then, based on the selection result, the output means reads and transmits or copies the image in the range from the odd-numbered marker line to the even-numbered marker line, which is one larger than the odd-numbered marker line.

FIG. 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, for example, line by line. A sheet of paper with faded letters as shown in FIG. 3 is used as the transmission document. When only part of the manuscript is to be transmitted, the portions P, . In order to specify P2..., multiple (four in the example) markers Ml, M! ．． M3, M
It is delineated by n...

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 is suitable.

2 is an image processing circuit that binarizes the image data read by CCD 1; 3 is a storage circuit including a RAM ROM that stores a program for executing the sending operation of the facsimile device; and 4 is a memory circuit necessary for transmitting the image data. A circuit for encoding, 5 a modem for modulating transmission data and sending it out to the telephone line, and demodulating received data input from the telephone line, 6 installed on the outer panel (not shown) of the facsimile. Operation keys including numeric keypad, start key, partial send key, partial cobby key, etc. 7 is a keyboard controller, 8 is an LCD display section provided on the panel,
9 is an LCD controller, IO is a thermal head for recording data received through a telephone line on recording paper,
11 is a circuit that drives the head IO, and 12 is a microprocessor that is connected to the above-mentioned circuit through a data bus DB and controls transmission and reception operations.

The facsimile with the above configuration can perform sending, receiving, and copying functions using the same operations as conventional ones. That is, after placing the manuscript on a manuscript table (not shown) and entering the telephone number of the other party manually,
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, marker lines M+, Mz, M3, and M4 as shown in FIG. 3 are marked on the manuscript to be placed on the manuscript table.
If the partial transmission key or the partial copy key is pressed, the process is executed according to the flowchart shown in FIG. That is, when any of the above keys is pressed (S 1
), set the transmission area register in MPUI 2 to O (S2). This register indicates the range in which the current document scanning position is surrounded by marker lines M, , M2 or M3, M4 (that is, the range surrounded by odd-numbered marker lines and even-numbered marker lines that are 1 larger than the odd-numbered marker lines). If the register value is O, the document scanning position is in the range before the first marker line or from the even-numbered marker line to the next odd-grained marker line (the next odd-numbered marker line). If there is no main marker line, it means that it is in the range from the rear edge of the document), and if the register value is 1, the document scanning position is from the odd-numbered main line to the next even-numbered marker line. (If there is no next even-numbered marker line, it means that it is in the range up to the rear edge of the document).

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 3.
4, the CCD scans and reads one line of the upper edge of the document. Then, the read l-line data is star-coded, sampled, and encoded, and then subjected to band compression processing (S
5). The compressed code for I lines obtained in this way is determined 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 l scanning lines, and it is assumed that such an all-black code does not exist on the document except when scanning marker lines Ml and Mz. standing under In other words, this means excluding cases where there are frame lines, cross lines, etc. on the document. If the compressed code of the read data is not an all-black code, the process advances to step S8, and the value of the transmission area register is set to "1".
Determine whether When you press the partial copy key or partial send key, the value of the register is set to O in step S2, and the value of the send area register is maintained at O until the main marker line is scanned, so in that case, the step Proceeding to S9, the compressed code of the line read earlier is not stored in the storage circuit 3. Subsequently, the scanner mode is rotated by one line to feed the document one line in the sub-scanning direction A, and the next line is read. In this way, one line at a time is read, but if the transmission area register is "0", all the read data is discarded.

Next, when the first marker line is conveyed to the COD reading position, the read data of that part is all black and the compressed code is an all black code, so the program proceeds from step S6 to step S37. Set the transmission area register to "L". Then, the program advances from S8 to Sll, and the data read earlier (all black code in this case) is stored in the memory.

Subsequently, the scanner mock is rotated by one line and the next line is read. Since the value of the transmission area register is 1 from when the first marker line M is detected to when the second marker line M2 is detected, the data read in each scanning line during that time is encoded into a compressed code and stored in the memory. is stored in 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 advances from step S6 to step S7 and changes the value of the transmission area register to 0. .

Thereafter, the value of the transmission area register is 0 until the third marker line M is detected, so the data read in each scanning line during that time is discarded.

As the document scan progresses and the third marker line M is detected,
Since the transmission area register is inverted to 0-1 in step S7, the period until the fourth marker line is detected is the same as the period from the first marker line M1 to the second marker line M2 described above. , S 1 1-S 1 2-S 3
-S4-S5→S6→S8-Sll processing is performed to encode the data read in each scanning line and store it in the memory.

Subsequently, when the fourth marker line M4 is detected, the transmission area register is inverted to O (S7), and the data read from then on up to the trailing edge of the document is discarded.

After scanning to the rear edge of the document as described above, the program advances from S3 to 313, and determines whether the key pressed in step S1 is a cobby key or a send key.
If it is a transmission key, the read data is sent to the line through the modem (S14), and if it is a copy key, the read data is decoded (315), and the thermal head of the receiver is driven to print it on recording paper. The read data is printed (S16).

In the embodiment, a case has been described in which four marker lines are drawn on the document, but it goes without saying that the number of marker lines is not limited to four. As can be understood from the flowchart in Figure 2, the range that the device in Figure 1 transmits or copies is the range from the odd-numbered marker line to the next even-numbered marker line, or the range surrounded by the next even-numbered marker line. If it does not exist, the range is from the odd-numbered marker line to the rear edge of the document.

Next, marker line M. ．． Mf, M,...Mn are usually scanned by the operator's hands, so it is difficult to scan them completely parallel to the main scanning direction, and they run somewhat obliquely. 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 slightly skewed, it is sufficient as a marker to ensure that all black data is obtained when reading on the marker line. It is preferable to use thick ones. As explained above, according to the present invention, by simply specifying the range to be sent or copied using a marker on a document, even if there are multiple specified ranges, all the ranges of the document image can be copied. It is very easy to use as it allows you to select and send or copy, and there is no need to cut out parts of the document as in the past.
