Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to diagnosis of a facsimile machine, and more particularly, to a facsimile machine having an automatic diagnosis function of a multi-communication port.

2. Description of the Related Art Conventionally, as a diagnosis of a facsimile apparatus of this type, a communication test is performed on each port from a diagnosis apparatus at a remote location.

Problems to be Solved by the Invention The conventional diagnosis described above uses a diagnosis device at a remote location, so that a faulty port cannot be confirmed unless a diagnosis is made from a remote location, and a failure is detected until a response is performed by maintenance personnel. Documents originating from ports have the disadvantage that they are not delivered.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and accordingly, it is an object of the present invention to provide a novel facsimile apparatus which can solve the above-mentioned disadvantages inherent in the prior art.

Means for Solving the Problems In order to achieve the above object, a facsimile apparatus having a multi-communication port according to the present invention is a facsimile apparatus having three or more multi-communication ports, wherein each port is connected to a network. Means for storing destination address information of each port, means for automatically transmitting facsimile encoded data from one port to another port of the same device, and normal communication by being able to decode normally on the receiving side. Means for recognizing; means for changing the combination of transmission / reception ports at the time of abnormal communication to perform communication with the own terminal port to detect a defective port; and means for not using the defective port in operational communication. .

Next, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

Referring to FIG. 1, reference numerals 1, 2, 3, and 4 denote communication control units for controlling transmission and reception, and 5 denotes a communication control unit 1, 2, 3, and 4, a CODEC unit 6, and a storage unit 9. A system control unit, 6 is encoding,
A CODEC unit for decoding, a scanner unit 7 for reading a document, a printer unit 8, and a storage unit 9 for storing encoded data are shown.

As an operation at the time of operation, the image information read by the scanner unit 7 is encoded by the CODEC unit 6, and the encoded data is accumulated in the accumulation unit 9. The stored encoded data is transmitted from the communication control unit 1 or 2 or 3 or 4.

 At the time of broadcast transmission, it is transmitted from a plurality of communication control units.

Next, the operation at the time of automatic diagnosis will be described. The diagnostic encoded data is stored in the storage unit 9. The ports of each communication control unit are connected to the address numbers 111, 222, 333, 444 shown in FIG. That is, the port of the communication control unit 1 is at the address “111”, the port of the communication control unit 2 is at the address “222”, and the port of the communication control unit 3 is also at the address “33”.
3 ", the port of the communication control unit 4 is connected to the address" 444 "(the address numbers are shown as an example). The address number information of each port is managed by the system control unit 5. Hereinafter, the port of the communication control unit 1 will be referred to as “port 1”.

First, communication is performed until normal communication can be confirmed with an arbitrary combination of ports according to a diagnosis start instruction from the operator.
For example, if transmission is performed from port 1 to address “222”, reception will be port 2. Here, if the port where normal communication can be confirmed for the first time is transmission from port 1 to port 2, the transmission operation of port 1 and the reception operation of port 2 can be said to be normal.

Next, the transmission operation of ports 3 and 4 can be confirmed by transmitting to port 2 in which the reception operation has been confirmed to be normal. The transmission operation of the remaining port 2 is determined by transmitting to another port 1 or port 3 or port 4.

The port determined to be defective in the transmission operation by the above operation is managed by the system control unit 5, and is not assigned to the transmission port in the normal transmission operation in the operation thereafter.

As described above, according to the present invention, the transmission operation of each port can be automatically diagnosed by performing an automatic loop-back test through a network in a multi-communication port, and the transmission from a bad port can be diagnosed. The effect of preventing non-delivery by calling can be obtained.
