Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a facsimile machine having automatic dialing and memory.

Conventionally, in a facsimile device having automatic dialing and memory, a document having a destination mark indicating the destination and an end mark indicating the end of the document is scanned from the destination mark to the end mark, and the destination corresponding to the destination mark is stored. At the same time, a redundancy removal signal is created by removing redundancy from the image information signal of the document, the redundancy removal signal is temporarily stored, and then the stored redundancy removal signal is transmitted to the specified destination. An image information communication system is used.

Figure 1 shows an example of this, in which image information of a document with a specified destination mark position is read by Scanner S, and this read mark code is converted into an actual telephone number by destination reading circuit AC. is,
That number is stored in the destination memory AM. Then, the communication control device automatically starts dialing by the dialing start command signal (a) from the system control device SCU.
The automatic dialing circuit AD dials the destination through the CCU, and the destination is called. On the other hand, the image information from the scanner S is temporarily stored in the memory M after its redundancy is removed by run-length encoding or the like by the data compression circuit DC. Next, when a transmission procedure completion command is given to the communication control unit CCU by the transmission procedure completion command signal (b) from the system control unit SCU, the compressed image information stored in the memory M is transferred to the system control unit
A data sending command signal (c) from the SCU is given to the memory M and the communication line is passed through the communication control unit CCU.
Sent to CC.

By the way, such devices are used in center machines and the like to process a large amount of originals, but the destination terminal side is not in a busy state, and the destination terminal side is in a busy state.
If reception becomes impossible due to problems with the paper feeding system, etc., transmission cannot be performed, and the memory M becomes full of information, causing an overflow and making it impossible to transmit to others. This is a big problem for a center machine or the like whose purpose is to use the device efficiently in full operation.

Therefore, the present invention has been made based on these circumstances, and its object is to provide a facsimile device that can prevent memory overflow and can perform operations for this purpose quickly and without waste. It's about doing.

In order to achieve such an objective, the present invention
Basically, it consists of an input means for inputting destination information, an automatic dialing means for automatically calling a destination according to the destination information inputted by this input means, and a memory for storing image information read by scanning the sent document. In the facsimile apparatus, the facsimile apparatus includes a determining means for determining whether communication is possible with the destination terminal that has been called by the automatic dialing means, and a determining means for determining whether communication is possible with the destination terminal that has been called by the automatic dialing means; an erasing means for erasing the image information stored in the information storage means; an uncommunicable destination storage means for storing and holding information on uncommunicable destinations; and an uncommunicable destination storage means for storing the destination information of the image information erased by the erasing means. storage control means for storing the image information in the image information storage means when the destination information inputted by the input means is already stored in the communication-disabled destination storage means; It is characterized by having the following.

The basic concept of the facsimile apparatus configured in this manner is to erase the image information of the original from the memory (image information storage means) when the destination terminal is unable to communicate.

In order to realize this, when the automatic dialing means makes a call to the destination based on the destination information input by the input means, and the destination terminal side is determined by the determination means to be unable to communicate,
The image information that has already been read and stored in the image information storage means is erased by the erasing means.

Further, there is provided a communication-disabled destination storage means for storing and holding destination information of a destination terminal with which communication is impossible by the storage control means, and thereafter, destination information for which a transmission request is made is stored in the communication-disabled destination storage means. If the image information is stored in the memory, the prohibition means prohibits the memory from storing the image information.

This makes it possible to eliminate unnecessary access to the memory for writing and erasing data, thereby dramatically improving the throughput of processing speed.

Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 2 is a block diagram of an embodiment of the present invention. In the figure, ADF is automatic document feeder,
OR is a sent manuscript, and OR′ is a manuscript that cannot be sent.
ST is a sorter for sorting originals OR' that cannot be sent and originals that have already been sent. AT is a communication-disabled destination memory for storing the destination number of a destination terminal that has become unable to communicate, and when a command signal (d) indicating that communication of the destination terminal is disabled from the system control unit SCU is input to the destination memory AM, The destination number stored in the destination memory M is transferred to the uncommunicable destination memory AT. And the destination memory
In the AM, the destination number that has entered the destination memory AM is compared with the contents of the uncommunicable destination memory AT. Furthermore, when the destination terminal receives a telephone call or the like to inform that the destination terminal has been repaired, the contents of the unreachable destination memory AT can be reset and cleared by the operator. (d) is a command signal, which is a system control device
Since the destination number currently stored in the destination memory AM has become unreachable from the SCU, this is a signal instructing to transfer this number to the unreachable destination memory AT, and also the destination number input to the destination memory AM. This is a signal that informs the system control unit SCU that is the number of a terminal that cannot communicate.

(E) is a signal instructing the sorter ST that the document cannot be transmitted. And in Figure 2,
Since the other parts are the same as those shown in FIG. 1, they are omitted here.

FIG. 3 shows the contents of an embodiment of the management table stored in the uncommunicable destination memory AT of the present invention. A document number is given from the system control unit SCU, and a destination number is attached to this document number.

FIG. 4 shows the contents of an embodiment of the management table of the memory M provided in the system control unit SCU of the present invention.

Next, the operation of this embodiment will be explained.

The general operation in which a document is set at a predetermined position by the automatic document feeder ADF, and the scanner S reads the destination mark on the document and sends the document is the same as that shown in FIG. 1, and therefore will not be described here.

When calling the destination terminal, if a problem occurs on the destination terminal side and reception is not possible, a judgment signal is issued from the destination terminal side and the communication control unit CCU
System control device through command signal (b)
Given to SCU. The system control unit SCU interrupts the transmission procedure, and instructs the destination memory AM to transfer the destination number currently stored to the communication-disabled destination memory AT by the command signal (d); Stored in destination memory AT. At this time, there is at least one page of transmitted image information that cannot be received in the memory M, but this image information is erased by the command signal (c). Next, documents are set one after another from the automatic document feeder ADF, and each time the destination is read and input into the destination memory AM. In this destination memory AM, each time the destination number is input, it is checked against the contents of the unreachable destination memory AT,
When the contents match, that is, when it is determined that the terminal with that destination number is unable to communicate, this is notified to the system control unit SCU by a command signal (d), and the system control unit
Prevent document numbers from SCU from being given. At this time, since the memory M is not given the memory management number for the document number from the system control unit SCU by the command signal (c), storage in the memory M is prohibited.

On the other hand, the sorter ST is switched to the transmission disabled side by the command signal (e) from the system control unit SCU.
Documents sent to the terminal with which communication has become impossible are classified as untransmittable.

Although the facsimile apparatus of this embodiment has been described as applying a document fixed scanning method, it goes without saying that the present invention is not limited to this, and can be applied to other methods without changing the gist of the invention. stomach.

Note that it is also possible to display on the destination terminal that the destination terminal has become unable to receive data due to a failure.

As explained above, according to the present invention, by arranging the uncommunicable destination memory and the sorter, it is possible to prevent memory overflow of the center facsimile device when the destination terminal fails, and the transmission to the destination terminal can be prevented. Since documents can be sorted as documents that cannot be sent, nighttime operation is also possible, and the device can be fully operated and used efficiently.
