2. Description of the Related Art Currently, facsimile machines are becoming more sophisticated and less expensive, and are widely used as a means of communicating image information. Many users interact with various facsimile machines and actually perform sending operations. The first operation of such a facsimile machine during transmission is to set a document. However, there are two ways to set the original: one with the reading side of the original facing up, and the other with the original facing down.

[0003] The difference in the way the original is set is that, for example, a CCD (Charge Coup) is used to read the original.
LED Device, Charge Coupled Device) or
Alternatively, it depends on whether a contact image sensor or the like is used. For example, when a CCD is used, the optical system using lenses becomes large, so the document reading section is provided inside the device, with the reading surface facing toward the top of the device. For this reason, the configuration is such that the document is inserted with its reading side facing down. Furthermore, when a contact image sensor is used, the document reading mechanism can be configured to be compact, and the document can be inserted upward and sent while checking the contents of the document.

[0004] In this way, in a facsimile machine, the method for setting the original differs depending on whether the scanner, that is, the image reading section is installed above or below the position where the original passes. There is. When a user alternately uses facsimile machines with different document loading methods, the user may set the document in the wrong direction and send the back side. If you make a mistake in loading the document with the right side and the front side, a blank recording sheet will be ejected from the receiving device, and the receiving side will notice that it has been sent in error. Then, the sending side becomes aware of the erroneous transmission due to notification from the receiving side which noticed the erroneous transmission, and then re-sends the same original. Due to this erroneous transmission, the receiving side will consume twice as much recording paper, and the sending side will incur twice the communication charges.

[0005] In order to solve such problems, there is a conventional technique described in, for example, Japanese Patent Laid-Open No. 10869/1983. In other words, the amount of encoded data obtained by encoding the scanned image information is counted and added, and the result is compared with a preset reference value, and documents that do not reach the expected density are detected by checking whether the originals are facing up or down incorrectly. It detects that the message has been inserted and immediately notifies the user on the sending side.

[0006]

[Problem to be Solved by the Invention] Conventional techniques for dealing with the problem of incorrectly inserting and transmitting the front and back sides of a document, for example,
The method described in Japanese Unexamined Patent Publication No. 10869/1986 did not give sufficient consideration to the receiving side. As a result, on the receiving side, it is not possible to immediately determine whether the received blank recording paper is due to a problem with the sending or receiving device, and confusion occurs, which reduces the reliability of the system as a whole. did not have sufficient effect. Furthermore, conventional devices that can detect when the wrong side of a document is inserted and transmitted do not take into account users who intentionally want to send white or nearly white documents, and send documents that are close to white. In this case, it is necessary to re-register the reference value, and after sending it, it is necessary to re-register the original reference value, which poses problems such as complicated operability.

It is an object of the present invention to solve the problems of the prior art, to immediately notify the receiving side of the detected transmission of incorrect insertion of the front and back sides of a document, to prevent confusion on the receiving side, and to prevent confusion on the receiving side. It is an object of the present invention to provide a facsimile device that can flexibly cope with low-quality originals and can improve the reliability of the entire system and transmission operability.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the facsimile apparatus of the present invention provides: (1) an image density value of a document calculated by counting and adding the amount of encoded data of encoded image information; A facsimile machine that detects mis-insertion and transmission troubles caused by incorrectly inserting the front and back sides of a document based on a comparison with a density reference value set arbitrarily in advance. The present invention is characterized in that a receiver-side information transmitter is provided to send information to the receiver-side device, and the receiver-side information transmitter immediately notifies a user on the receiver side of the occurrence of a transmission trouble such as incorrectly inserting the wrong side of a document. (2) In the facsimile apparatus according to claim 1, a comparison operation control unit is provided to control a comparison operation between the calculated image density value and the density reference value based on a user's instruction, and the facsimile apparatus is provided with a comparison operation control section that controls a comparison operation between the calculated image density value and the density reference value, When transmitting, the comparison operation control section controls the comparison operation between the calculated image density value and the density reference value.

[0009]

[Operation] In the present invention, when an erroneous transmission caused by a user's mistake in setting a document is detected during a transmission operation, erroneous transmission information is sent not only to the sending side but also to the receiving side. As a result, the user on the receiving side can immediately know that the printed blank recording paper is due to an error in setting the original on the sending side, and confusion on the receiving side can be avoided. Furthermore, when transmitting a document that is nearly white in color, the user on the transmitting side can easily control, for example, stop, the detection operation of the wrong insertion and transmission trouble of the document by operating the operation unit. As a result, the user can transmit an extremely low-density document, which would require a complicated operation to change the reference value in the conventional technique, by simply inputting an instruction.

Embodiments Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the structure of a facsimile machine according to the present invention.

The facsimile device 1 of this embodiment includes a CCD 2 that reads image information from a document, an A/D converter 3 that converts an analog signal (image information) from the CCD 2 into a digital signal, and a white digital signal (image information). A binarization processing unit 4 that quantizes into one of the values of and black, a system bus 5 that transmits various signals such as binarized image information, and an encoding unit for the binarized image information; A CODEC (Coder Decode) decodes received encoded data.

processing unit, central processing unit) and R which stores the operating procedures of the facsimile machine 1.
A system control unit 9 includes an OM (Read Only Memory), etc., and controls the overall operation of the facsimile machine 1, including the processing operations according to the present invention, and a system control unit 9 that receives operation instructions from the user and controls the device. an operation display section 10 that displays the operating status; a drive control section 11 that controls the drive of a sensor that detects the setting of a document (not shown); and a drive motor for conveying the document;
It consists of a plotter 12 that prints an image on recording paper based on the received image information.

Furthermore, the system control section 9 sends a notification signal to a main control section 13 that controls the operation of the entire apparatus, and a density comparison section 14 that is a conventional technique and detects incorrect insertion of the front and back sides of a document based on the density value. a notification signal sending section 15; a comparison operation control section 17 which is the present invention and controls the operation of the document wrong insertion transmission detection section 16; and a document wrong insertion transmission detection section 16 The receiving side information sending section 18 sends out wrong insertion transmission information of the wrong side of the document to the receiving side device based on the operation of the notification signal sending section 15 of 16.

With such a configuration, the facsimile machine 1 according to the present invention can detect erroneous transmission caused by a mistake in setting a document during a transmission operation, stop the subsequent document reading operation, and In addition to carrying out conventional operations such as notifying the user of the device, it also sends information on erroneous transmission to the receiving device, and stops detection of erroneous document insertion and transmission based on operation instructions from the user of this device (control). ) perform the action. This makes it possible to solve the problems that occur with the prior art.

The processing operation of the facsimile machine 1 during transmission according to the present invention will be described below. First, the CCD 2 reads the image information of the original. The read image information is an analog signal, and is converted into a digital signal by the A/D converter 3 for processing such as encoding. The image information converted into a digital signal is quantized into white and black values by a binarization processing section 4. The binarized image information is sent to the CODE via the system bus 5.
Enter into C6. The CODEC 6 encodes and compresses the binarized image information in order to efficiently transmit it. The compressed image information is modulated by the modem 7, and transmitted by the NCU 8 to the receiving device instructed by the user via the operation display unit 10.
Send via line.

[0016] At this time, the original front and back erroneous insertion transmission detection unit 16 uses the density comparison unit 14 to calculate a density value from the image information encoded by the CODEC 6, and compares it with a reference value. If the density comparator 14 outputs a comparison result indicating that the density of the original is extremely low, the notification signal sending unit 15 determines that there has been a problem in incorrectly inserting the front and back sides of the original and transmitting the original, and sends a transmission processing stop signal. Based on this signal, the main control section 13 stops the operation of the drive control section 11, and causes the operation display section 10 to display the details of the trouble and generate a buzzer sound. This makes it possible to reduce communication costs by avoiding unnecessary transmissions thereafter, and also allows the user to immediately know that the document has been set with the wrong side facing up and sent.

Furthermore, the facsimile machine 1 of this embodiment is provided with a receiving side information transmitting section 18, and based on the signal from the notification signal transmitting section 15, the receiving side device also transmits a message indicating that the original is wrongly inserted. It can let you know that there is a problem. As a method for notifying the receiving side device of a trouble by the receiving side information sending unit 18, for example, a pre-registered message may be sent via the modem 7 and the NCU 8, or a simple error sound activation signal may be sent. It's okay. Then, the facsimile machine on the receiving side that receives such a trouble notification prints out a message or generates an error sound. In this way, the receiving user can
You can immediately know that the blank recording paper that is output is due to a trouble in the wrong insertion and transmission of the wrong side of the document.

On the other hand, if the user on the sending side intentionally
Sometimes you may send an original that is almost white. In such a case,
Even though the user has correctly set the front and back sides of the original document, there is a possibility that the incorrect insertion/transmission detection unit 16 detects a trouble in the incorrect insertion/transmission of the wrong sides of the original document, and a troubleshooting process is performed. In response to such a situation, the facsimile apparatus 1 of this embodiment is provided with a comparison operation control section 17. That is, based on the user's instruction input from the operation display unit 10, the comparison operation control unit 17 stops the function of the document wrong insertion/reverse insertion transmission detection unit 16. As a result, even originals that are nearly white can be sent without troubleshooting.

It should be noted that the comparison operation control section 17 does not simply stop the function of the document wrong insertion/transmission detection section 16;
It may also be possible to adjust the comparison accuracy of the density comparison section 14 of the document wrong insertion transmission detection section 16. However, in this case, the user needs to perform delicate adjustment operations.

As described above, according to the facsimile machine 1 according to the present invention, during the sending operation, the users on the sending side and the receiving side can immediately know about the erroneous transmission caused by the mistake in setting the original. be able to. Then, based on the operation instructions from the user on the sending side, the operation of detecting the wrong insertion and sending of the document on both sides can be controlled, and the sending operation can be performed in a manner that flexibly corresponds to the density of the document.

[0021]

[Effects of the Invention] According to the present invention, it is possible to immediately notify the receiving side of the detected wrong-sided insertion and transmission of a document, thereby preventing confusion on the receiving side, and flexibly responding to documents with extremely low density. However, it is possible to improve the reliability and operability of the entire system.
