Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that converts an image of a document into an electrical signal and transmits the same, and records an image on paper from the received electrical signal.

[Conventional technology and its problems]

Reflecting the current information society, facsimile machines are rapidly becoming popular as a mainstay of office automation, and their applications are expanding into all fields.
For example, in the field of education, there is a learning method in which answers created by students in remote areas are sent to the teacher using facsimile, and the teacher corrects the answers and then sends them back to the students by facsimile. It is used for correcting and proofreading printed manuscripts. In such applications, based on one document, transmission of the document by facsimile and addition to the received document are repeated.

For additions, a color (for example, red) that is different from the color of the document (for example, black) is often used to make the added portion easier to see.

In such cases, conventional facsimiles have a problem in that the facsimile transmission and reception are repeated many times, resulting in a significant drop in image quality and making it difficult to see.

In addition, since it is generally not possible to distinguish colors with facsimiles, even if the color of the added portion is changed as described above, the color remains the same, and the problem remains that it is difficult to see.

[Technical means for solving the problem] In view of the above-mentioned problem, the present invention provides a facsimile device that can prevent image quality from deteriorating even if transmission and reception are repeated many times. The technical means for this purpose includes means for transmitting document identification information for identifying the document to be transmitted.

[For production]

At the time of transmission, document identification information for identifying the document is sent in addition to the image signal of the document, and the receiving party can determine whether the recorded paper is actually being sent based on this document identification information. You can check whether the recording paper is suitable for the document you are using.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing the general structure of a facsimile machine 1. As shown in FIG. The facsimile machine l includes a document table 4 on which a document 2 for transmission is placed, and a reading gutter 5 for reading an image of the document 2 sent from the document table 4 at the time of transmission.
, a paper cassette 6 for storing the recording paper 3 for reception, a printing gutter 7 for printing an image on the recording paper 3 sent out from the paper cassette 6 at the time of reception, an ink ribbon 8 used for printing, It consists of an ejection tray 9 for ejecting the original 2 or printed recording paper 3, and a large number of rollers 10, 1112, 13, 14, 15, and the like.

The reading nozzle 5 is of a photoelectric conversion type, consisting of a light source 16 such as a light emitting diode or a fluorescent lamp, and an image sensor 17 such as a MOS image sensor or a CCD image sensor. A filter 18 is provided which absorbs the color of the print by the ribbon 8. For example, if the ink ribbon 8 is red, the filter 18 is also red, and among the images drawn on the original 2,
colors other than red are read by the reading head 5;
Transmitted as an image signal. Therefore, the image to be sent to the other party is drawn on the document 2 in a color other than red, for example black.

Referring also to the block diagram of FIG. 2 showing an outline of the circuit configuration of the facsimile machine 1, a barcode reader 19 is provided above the document table 4. Barcode 2 printed on the tip
1 (see Figure 5). The barcode 21 is for identifying the manuscript 2 to be transmitted, and is either written on the manuscript 2 from the beginning or, as described later,
Once transmitted by the facsimile machine 1, it is printed by the printing hand door. When the barcode 21 is read by the barcode reader 19, the document identification information creation section 32 creates document identification information based on the barcode 21. This is temporarily stored in a buffer within the document identification information creation section 32, and then the line control section After the transmission destination is selected in step 34, the image signal is transmitted prior to the image signal. The recipient of the transmission is
Based on the sent document identification information, it is checked whether the set reception recording paper is suitable for receiving the image of the document 2. However, the reading of the barcode 21 by the barcode reader 19, the transmission of document identification information, or the above-mentioned check performed by the other party are performed by the input unit 41 such as a keyboard or switch.
Alternatively, depending on the content of the barcode 21 or the presence or absence of the barcode 21, the system control unit 39 selectively controls whether or not to perform the operation.

It was mentioned earlier that the barcode 21 is printed by 7 dos 7 at the time of transmission, but the contents of the barcode 21 can be entered from the input section 41 or by first printing the document 2 on the document table 4. When set to , the random number generator in the system control unit 39 automatically generates a random number.

In this example, the original ! used at the time of transmission! ? &2 is used as recording paper 3 during reception. Therefore, at this time,
The original 2 is placed on the original table 4, and the barcode 21 is read by the barcode reader 19.

Based on the barcode 21 read by the barcode reader 19, paper identification information is created by the paper identification information creation section 43, and this is temporarily stored in a buffer within the paper identification information creation section 43. When document identification information is sent from the other party during reception, the collation unit 36 collates the paper identification information and the document identification information, and the set recording paper 3 for reception is checked.
is suitable for receiving the image of the original that the other party is trying to send. As a result of the check, if the recording paper 3 is compliant, a signal is sent back to the other party to permit transmission of the image signal.

If the condition is not met, a warning sound is emitted or a message to that effect is displayed on the display unit 40 to issue a warning. However, whether or not the comparison check between the paper identification information and the original identification information is performed depends on the contents of the original identification information transmitted from the other party, the presence or absence of the original identification information, or the operation input from the input unit 41. are selectively controlled by the system control unit 39.

In FIG. 2, reference numeral 31 denotes an image signal generation unit that performs scanning and the like to generate an image signal, 33 denotes a modulation unit, and 35
is a demodulation section, 37 is a print control section, 38 is an image control section, 42
is a driving part such as a motor or a clutch.

Next, the function and operation of the above-mentioned facsimile machine 1 will be described in 2.
A case will be described in which back-and-forth communication is performed between the facsimile machines Wla and lb on the table based on one document.

In FIG. 3, first, in order to perform transmission from the facsimile machine 1a, the line control unit 3 of the facsimile machine 1a
4 and the system control unit 39 perform the connection operation (step #1). When the facsimile machine 1b on the receiving side completes reception preparations (step #2), the reading head 5 of the facsimile machine 1a on the sending side reads the image of the original 2 in a color different from the color of the filter 18 (black). The image is read (step #3) and sent. At this time, the random number generator in the system control unit 39 also transmits the ordered manuscript identification information and corresponds to this manuscript identification information.

A barcode 21 is printed on the leading edge of the document 2 (Suftemp #4).

The facsimile machine 1b on the receiving side prints an image on the set recording paper 3 in the color of the ink ribbon 8 (red), and also prints a bar on the leading edge of the recording paper 3 based on the sent document identification information. Print code 21 (step #6).

The recipient writes on the recording paper 3 with a black writing instrument in order to proofread or correct the content received by the facsimile device 1b (step #7). Thereafter, the facsimile device fib transmits the data to the facsimile device 1a. On the side of the facsimile machine 1a, in order to use the previously transmitted original 2 as the recording paper 3 for reception, the original 2 is set in advance on the original table 4 (step #8).

The same connection operation as described above is performed on the facsimile device 1b on the sending side (step #9), the receiving side prepares for reception (step #10), and the recording paper 3 with added notes is set as the original document 2 on the sending side. , reads the barcode 21 of the original 2 (step #11), and transmits original identification information (step #14).

On the other hand, the facsimile machine 1a on the receiving side determines whether or not this communication is a reply, that is, whether the communication requires matching the recording paper 3 on the receiving side to the original document 2 on the sending side (step #12). ). If no, general reception is performed (step #13).

If YES, the document identification information sent from the sending side is compared with the paper identification information of the recording paper 3 set in the facsimile machine 1a on the receiving side, and it is determined whether the recording paper 3 is compatible. Check (Step #15).

If it is compatible, the sending facsimile device 1b
The original 2 is read (step #17) and an image signal is transmitted (step #18). When reading the original 2, only the black image added later out of the images of the original 2 is selected by the filter 18. In the facsimile machine 1a on the receiving side, the added image is printed on the recording paper 3 in red using the ink ribbon 8 (steps #19 and 20). ... Therefore, on the facsimile machine 1a side, the parts that the other party (on the side of the facsimile machine 1b) has added such as proofreading and corrections are printed on the original document 2 itself created on the facsimile machine 1a side. There is no reduction in image quality at all,
Moreover, while the original 2 is black, the added parts are red, making it very easy to see,
Since only the added portion is transmitted from side b, the time required for transmission is significantly reduced, and communication charges are also significantly lower.

In the above embodiment, in step #4 barcode 21
Although the barcode 21 is printed on the document 2, it is also possible to use the document 2 on which the barcode 21 is printed in advance. Although the barcode 21 is read by the barcode reader 19, it may also be read by the reading gutter 5.

In that case, in order to make it easier to read the barcode 21, the filter 18 may be made movable and retracted, or as shown in FIG. An image sensor 17b dedicated to the barcode 21 may be provided, and the timing at which the barcode 21 is read will vary depending on this. When using the document 2 that was once used for transmission as the recording paper 3, the roller 10 is rotated and the barcode 21 of the recording paper 3 is
It is necessary to feed the recording paper 3 to a position where it can be read. In this case, if the recording paper 3 does not match the original document, the roller IO may be reversed after reading the barcode 21 to issue an alarm. Instead of the barcode 21, letters, numbers, and other symbols may be used.

The parts of the original 2 on the facsimile machine 1a that do not need to be sent, such as the frame for writing the original and pre-printed parts such as questions, are colored the same as the color of the ink ribbon 8 (red in the above embodiment). and facsimile machine 1b.
If the recording paper 3 having the same pre-printed portion is used on the side as well, the amount of images to be transmitted will be reduced, and the time required for transmission will be further reduced.

In the above embodiment, the ink ribbon 8 and the filter 1
The color 8 and the color of the document 2 may be colors other than red and black. The color of the recording paper 3 may be changed by replacing the ink ribbon 8. In addition to being fed from the document table 4, the recording paper 3 may be automatically fed from the paper cassette 3. At this time, the barcode sensor 20 is provided in the paper feed path, the paper is fed once to the barcode detection position, and when it is determined in step #15 that the paper is not compatible, the roller 12 is reversed. . Furthermore, it is easy to provide a dedicated feeding port for feeding the original document 2 once sent again.

In addition, the telephone number of the sender is also received in step #5, and the telephone number is printed in a barcode in step #6, and automatic dialing is performed based on the barcode when transmitting this recording paper 3. You can also do this.

〔Effect of the invention〕

According to the present invention, since document identification information for identifying the document is transmitted at the time of transmission, this document identification information allows
It is possible to check whether the recording paper on the receiving side is compatible with the transmitted original. Therefore, by keeping these formats and pre-printed parts the same between the sending document and the recording paper for receiving, or by making the same format and pre-printed parts, or by making the same document based on one document, the document sent by facsimile and the received document can be changed. When additions to the above are repeated, all the information can be transmitted without transmitting the common parts (by transmitting only the necessary parts. This makes it possible to transmit and receive multiple times. It is possible to prevent the image quality from deteriorating even if the image is repeated, and by making the color of the original image and the color of the print different, the received image becomes very easy to see.
