Description

Description: TECHNICAL FIELD The present invention relates to a FAX mail system that stores transmission data in an external storage device connected to a FAX device and transmits the data via a storage and exchange device. The present invention relates to a destination error correction method that can correct an incorrect destination without re-inputting image information.

2. Description of the Related Art Generally, in order to transmit image information, it is necessary to input destination data such as a fax number equivalent to a telephone number for specifying a communication destination and to read an image. If the destination is wrong, the reading of the image is useless, and it is necessary to suppress the reading of the image.

When a single fax machine transmits, after connecting to the destination,
The image is read after the startup procedure of the AX device is completed. Therefore, in the case of this type of single fax device, if incorrect destination data, for example, a number for only a telephone, is input, the other fax device is not activated, and no image is read.

Therefore, the related art relating to the handling of the error of the transmission destination generally suppresses the connection itself to the destination, thereby suppressing useless image reading at the time of the destination error.

Incidentally, as this kind of prior art, for example, Japanese Patent Laid-Open No. 62-21
A technique described in, for example, Japanese Patent No. 7777 is known.

Further, the fax mail system according to the related art performs an operation as described below.

That is, a fax mail system is a system in which image information read from an input fax machine is stored in a storage and exchange device and transferred to an output fax machine based on control information, and is independent of the state of the output fax machine. In this system, the input fax machine can perform transmission processing.

The control information is information for the storage and exchange apparatus to control data transmission, and includes destination data for specifying a facsimile apparatus to be output, service data for specifying a service type, and the like. Further, there are roughly two types of fax mail systems, which are called a closed network and an open network, respectively.

The closed network is a network in which destination data of all facsimile devices with which communication is performed is registered in advance in the storage and exchange device, and can output only to the facsimile devices registered in the system. For this reason, in each storage and exchange device, the destination data of all the fax devices in the system and the destination data of the storage and exchange device to which each fax device is connected are registered, and the validity of the input destination data is confirmed. You. Further, the storage and exchange device for storing transmission data is registered in advance for each fax device, and does not need to be designated by the operator.

An open network is a network in which destination data of a fax device is not registered, and can output to any fax device. Therefore, the storage and exchange device does not check the validity of the input destination data, and first, the storage and exchange device for storing the transmission data is specified by the operator.

Hereinafter, operations in these networks according to the related art will be described with reference to the drawings.

FIG. 6 is a diagram showing a detailed operation sequence in the closed network.

In FIG. 6, first, the operator inputs destination data of the output fax machine from the input fax machine. Input side F
After the AX device is connected to the storage and exchange device in which the fax device is connected in advance, the input fax device outputs control information generated from the input destination data,
Transfer to the storage and switching device.

The store-and-forward device checks whether a fax machine corresponding to the destination data in the control information exists in the system based on the registered destination data. In this inspection, if a corresponding FAX device exists in the system, the input FAX device reads an image based on the destination data check result information from the storage and switching device, and generates image information. If there is no corresponding FAX device, the connection between the input FAX device and the store-and-forward device is immediately disconnected, and the image is not read by the input FAX device.

FIG. 7 is a diagram showing a detailed operation sequence in the open network.

In FIG. 7, first, the operator inputs data designating the storage and exchange device and destination data of the output fax device from the input fax device. After the input-side FAX device is connected to the storage and switching device specified by the operator, the input-side FAX device transfers control information generated from the input destination data to the storage and switching device.

The input-side fax device further reads the image to generate image information, and transfers this to the storage and switching device.

The storage and exchange device generates transmission data based on the received control information and image information, stores the data in an external storage device connected to the storage device, and communicates based on the destination data of the output fax device in the control information. Connect the line. When the line is connected to the other party's fax machine, the storage and switching apparatus determines that the destination data is normal, and transfers the transmission data to the fax machine. If the line is not connected to the other party's fax machine, the storage and switching apparatus determines that the destination data is abnormal, discards the stored transmission data, and reports the abnormality to the input fax machine.

That is, in the closed network, useless image reading can be suppressed by disconnecting the connection with respect to the error of the transmission destination, but in the open network, useless image reading cannot be suppressed.

As described above, in the related art, a countermeasure is considered only when an error in the destination is found before the image is read.

Further, as another conventional technique, transmission data composed of image information and control information input from a facsimile
There is known a FAX mail system in which data is temporarily stored in an external storage device connected to the device, and then transmitted via a storage and switching device.

In this FAX mail processing, an image is read before the input FAX device is connected to the storage and switching device, and transmission data is stored in an external storage device connected to the FAX device.
Then, the facsimile apparatus transfers the transmission data to the storage and exchange apparatus, and the storage and exchange apparatus accumulates the transmission data in an external storage device connected to the apparatus and assigns a storage serial number.

In the case of a closed network, the store-and-forward device checks whether a fax machine corresponding to the destination data in the control information exists in the system based on the destination data registered in its own device. The transmission serial number of the transmission data and a message indicating error detection are transferred to the input fax machine.

That is, in a fax mail system in which transmission data including image information and control information input from a fax device is temporarily stored in an external storage device connected to the fax device, it is a closed In the case of a network or an open network, after the image is read.

[Problems to be Solved by the Invention] In the above-described related art, no consideration is given to a case where there is a destination error, and if there is an error in the destination even though the read image itself is normal. However, the image information is also discarded and becomes invalid, and therefore, it is necessary to re-input the image information.

An object of the present invention is to provide a destination error correction method in a fax mail system which solves the above-mentioned problem of the prior art and makes it possible to effectively use image information once read even when destination data is incorrect. To provide.

[Means for Solving the Problems] According to the present invention, the object is to store transmission data including image information and control information in an external storage device connected to a facsimile device, and then transmit the data via a storage and switching device. Fax to
In the mail system, the store-and-forward device includes the FA
The transmission data from the X device, information such as a data storage serial number designating the transmission data, and the destination data are temporarily stored in an external storage device connected to the own device. If there is an error in the destination data, the data storage serial number is used. When a message indicating that there is an error in information and destination data is transferred to the fax device to prompt input of correct destination data, correct destination data and information such as a data storage serial number are input from the fax device. Generating new transmission data by combining the image information of the transmission data specified by the information such as the storage serial number and the control information generated from the correct destination data, and generating the new transmission data by the information such as the storage serial number. To be stored in an external storage device connected to the storage and exchange device, and to transmit this transmission data to the destination fax machine. Is achieved by

[Operation] When there is a destination error in the transmission data previously transmitted from the transmitting fax machine, the storage and exchange apparatus notifies the transmitting fax machine of the error together with information such as the data storage serial number. After that, when the operator inputs the information such as the data storage serial number and the corrected destination data of the communication partner FAX device by the operator, the transmission-side FAX device stores the control information generated from the destination data and the input information. Transfer to switching equipment.

When the storage and exchange apparatus receives information such as a data storage serial number and control information from the facsimile apparatus, the image information of the transmission data corresponding to the reception information among the transmission data stored in the external storage device and the reception control New transmission data including information is generated, and the transmission data is replaced with transmission data corresponding to the reception information and stored in an external storage device. The storage and exchange device then faxes the transmission data to the destination FAX in accordance with the destination in the control information in the transmission data.
Send to device.

According to the present invention, even when a destination is erroneously input, the destination can be corrected without re-inputting the image information, and the image information can be transmitted to the other party's fax machine.
