Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly, to a facsimile machine capable of preventing all unnecessary received documents such as direct mail from being output.

[0002]

2. Description of the Related Art In recent years, with the widespread use of facsimile machines, it has been popular to send public notices of various products by direct mail to a large number of unspecified parties. Generally, a facsimile machine always stores image information to be received. However, since most of the above-mentioned direct mails are unnecessary for the recipient, when such direct mails are sent, a record is made. Paper is wasted.

The wasteful consumption of the recording paper is one of the factors that have a serious influence on the deterioration of the global environment. That is, in recent years, the phenomenon of the desertification of the earth due to the felling of wood has been extremely advanced, and one of the causes is that a large amount of the felled wood is used as paper. Therefore, it is required to protect the global environment by reducing paper consumption, reducing timber cutting.

As a means for reducing the consumption of paper in order to solve such a point, for example, Japanese Patent Laid-Open No. 64-772.
The one described in Japanese Patent Publication No. 77 is known. This is a facsimile device that receives image information from a plurality of destinations via a public telephone line network, in which the telephone numbers of the destinations that need to be communicated are registered in advance, and the sender of the image information is received. If the sender's telephone number is registered and the sender's telephone number is registered, the received image information is recorded immediately, while if the sender's telephone number is not registered, the sender's telephone number and The received image information is stored, a part of the image information is recorded, and the operator visually judges the image information to judge whether the stored image information is recorded or erased. I am trying.

For this reason, when unnecessary image information such as direct mail is received, the image information is temporarily stored, and if the sender's telephone number indicates that it is not an important destination, the received image information is not recorded. It can be erased and the waste of recording paper can be reduced.

[0006]

However, in such a conventional facsimile apparatus, since it is a facsimile apparatus which receives image information from a plurality of destinations via a public telephone line network, an image of an analog line is not received. Only the information could be received, and only the image information processing received from this line could be performed.

In addition, if the telephone number of the other party that needs communication is registered in advance, the telephone number of the sender is identified when the image information is received, and if the telephone number of the sender is registered, Since the received image information was recorded immediately, the registered recipient's image information is always recorded, and if there is a duplicate document or a document that is unnecessary even for a specific recipient, as a result, The recording paper has been used up.

Further, when the sender's telephone number is not registered, the sender's telephone number and the received image information are stored and a part of the image information is recorded. Since a specific management number or the like is not given to the receiver, it is necessary for the receiver to judge whether the received image information should be recorded or erased each time, that is, the facsimile device when receiving the received information. There was a problem that the processing of the image information was very troublesome because the receiver had to be near.

Therefore, in the invention described in claim 1, a management number is given to all the image information received from the digital line control means or the analog line control means, and only the first part of the image information is printed out, and the remaining image information is printed. Information is recorded or deleted depending on the receiver's judgment and management number input, preventing unnecessary image information such as direct mail received from digital or analog lines from being printed. It is therefore an object of the present invention to provide a facsimile apparatus which can reduce the waste of recording paper and can process received documents for each communication unit with a management number to facilitate the processing operation.

According to the second aspect of the present invention, by outputting the hard copy according to the first part of the image information and the management number only in the designated time zone, the necessity / unnecessity of the received image information in the designated time zone. It is possible to provide a facsimile device with high performance, which enables the normal facsimile device to be received in other time zones and to be used properly according to the time period. Has a purpose.

According to a third aspect of the present invention, when the designated time setting means is operated, a list of the telephone number or ID code of the image information and the management number is displayed in one communication image information unit or a plurality of communication images. By collectively outputting in units of information, the first part of the received image information is not output, and the document specified from the list of the output telephone number or ID code and management number is recorded or erased. Thus, it is an object of the present invention to provide a facsimile apparatus capable of significantly reducing the waste of recording paper.

Further, the image data compression / decompression unit 8 receives the message compression mode (MH system or MR system) for decompression from the activation information from the SCU 2, and prepares for decompression. In addition, the writing unit 5 is an SC
Preparation for writing is performed using A4, B5, etc. according to the start information from U2.

Upon completion of these preparations, SCU2
The first page of the received message output from the HD is called and sent to the image data compression / expansion unit 8. Image data compression / decompression unit 8
Decompresses the received image information and sends it to the image processing unit 7.
At this time, the image processing unit 7 converts the management number into image data at a suitable position in the received image information, writes the management number, and sends it to the writing unit 5.

The writing unit 5 records the received image information on a recording sheet (step S4). When the SCU 2 finishes reading the first page, the SCU 2 sends an output end notification to the image processing unit 7, the image data compression / decompression unit 8 and the writing unit 5 via the system bus 11. Therefore, the image data compression / decompression unit 8 receives the end notification from the SCU 2 and ends the processing. Further, the writing unit 5 records all the received image information and ejects the paper, and then ends the processing.

At this time, the receiver reads the electronic message output to the copy tray in step S5 and determines whether or not the electronic message is necessary. At this time, if it is determined that the message is unnecessary, the process proceeds to step S6, the image information output mode is operated from the operation unit 6 to select the message not required, and the management number recorded in the message being output is displayed on the numeric keypad. Enter from.

At this time, the operation unit 6 sends the management number input by the receiver to the SCU 2 via the system bus 11. S
The CU 2 sets the entire text (including the first page) of the received electronic message corresponding to the management number received from the operation unit 6 in step S7 to H
The process is erased from D and the current process ends. On the other hand, when the receiver determines that the received message is required in step S5, the image information output mode is operated from the operation unit 6 to select the message required in step S8, and is recorded in the output message. Enter the registered control number using the numeric keypad. Therefore, the operation unit 6 notifies the SCU 2 of the management number input by the receiver via the system bus 11. The SCU 2 reads the second and subsequent pages of the received message corresponding to the management number received from the operation unit 6 from the HD, records the same on recording paper, and ends the current processing. After that, when the execution key is released, normal reception processing of the facsimile device 1 is performed.

In this way, this function assigns a management number to the image information received from the G3 communication control unit 9 or the G4 communication control unit 10 and prints out only one copy of the image information, and the remaining image information is printed by the recipient. Since either the recording or the erasing process is performed by the judgment and the input of the management number, the image information received from the G3 communication control unit 9 or the G4 communication control unit 10 can be processed, and the direct processing can be performed. It is possible to reduce waste of recording paper without printing unnecessary image information such as mail. Further, it is possible to determine whether all the received documents are necessary or unnecessary, and to remove all the unnecessary documents, which can reduce the waste of recording paper. Further, the received document can be processed by the management number for each communication unit, and the processing operation can be performed very easily.

FIG. 3 is a flow chart of the received image information program stored in the ROM and executed by the SCU 2.
This flowchart is executed when the time is designated without operating the execution key for executing the flow shown in FIG. In this case, the recipient inputs the designated time zone from the numeric keypad in advance. After this, the SCU2 sends the input time zone information to the SCU2 via the system bus 11.
To notify. At this time, the SCU 2 receives the time zone information from the operation unit 6 and stores it in the memory unit 3.

Then, in step S11, it is determined whether or not there is a reception, and if there is a reception, the PSTN or ISDN is received.
It is determined that there is an incoming call from any one of the above, and the process proceeds to step S12. The SCU 2 starts monitoring of the above-mentioned time zone, determines whether or not the current time is in the designated time zone in step S12, and if it is determined that the current time is not in the designated time zone, the step S13. Proceeding to step 1, the normal reception process, that is, all the received electronic messages are recorded on the recording paper by the writing unit 6 and output.

On the other hand, if it is determined in step S12 that the time is in the designated time zone, the process proceeds to step S13 to perform the same processing as the flowchart shown in FIG. Then, the process returns to S11 again and the designated time period is monitored. After the completion of the series of processes, when the switch that disables this function is selected by the operation unit 6, this notification is immediately notified to the SCU 2 via the system bus 11. SCU
When this notification is given, 2 erases the present time zone information stored in the memory unit 3, and at that time, performs a normal reception process for the received message.

As described above, the function can output the hard copy according to the first part of the image information and the management number only in the designated time zone by inputting the designated time. It is possible to judge whether the received image information is necessary or not, and to receive a normal facsimile device during the other time zones.
As a result, it is possible to properly use the facsimile device according to the time zone and improve the usage performance.

FIG. 4 is a flow chart of the received image information program stored in the ROM and executed by the SCU 2.
This flowchart describes a method of designating a time, registering a telephone number or ID code of a specific destination, and storing received image information in the memory unit 3 without outputting the first page. In this case, the operation key for executing the flow of FIG. 2 is not operated, and the numeric keypad of the operation unit 6 is operated in advance to input the telephone number or ID code of a specific destination, and the numeric keypad is operated to specify the designated time period. And then operate the list creation switch. In the present embodiment, description will be made assuming that the ID code is input.

First, when an incoming call is received from either PSTN or ISDN, the SCU 2 starts monitoring the above-mentioned time zone, associates the image information received during this time zone with the management number, and sets it as one communication image information unit. HD of memory part 3
(Steps S21 and S22). At this time, SC
U2 refers to the ID code of the transmission source, and when this ID code matches, this ID code is also stored in the HD in association with the image information. At this time, the image information of the first page is not output. In this flow, the operation from receiving the image information to accumulating it in the memory unit 3 is the same as in the flowchart shown in FIG.

When appropriate received messages are stored in HD,
For example, when 20 communications have been accumulated, the image information associated with the management number is created and output as a list together with the management number and the ID code. Next, the SCU 2 reads the received message information from the memory unit 3, and the image processing unit 7
Is sent (steps S23 and S24). At this time, the image processing unit 7 changes the received message text message list as shown in FIG.
An image is formed based on the received electronic message information received from 2 and sent to the writing unit 5. The writing unit 5 records in the received message list that is the received image information (step S25), and enters a standby state when the output is completed.

The receiver judges the necessity or unnecessaryness by looking at the received message list, and the operation unit 6 displays, for example, I
If the D-code is the unregistered sender, the management number of the unregistered sender is entered from the ten-key pad to output the first page of this document and determine whether to delete or output. .. This operation is similar to that of the flowchart of FIG.

As described above, when the designated time zone is input with the ten keys, this function displays a list of the telephone number or ID code of the image information source and the management number in one communication image information unit or a plurality of communication image information units. Since the data is collectively output in units, it is possible to record or erase the document specified from the list of the output ID code and the management number without outputting the first part of the received image information. .. As a result, the waste of recording paper can be significantly reduced. This function is very effective when executed on holidays. The reason is that, in general, the direct mail of the facsimile apparatus is often sent on holidays.

In the present embodiment, the designated time zone is directly input with the ten-key pad, but the present invention is not limited to this, and the operation unit 6 is used.
It is also possible to provide a designated time setting mode in and specify the time only when this operation mode is operated. In this case, information indicating that this mode is valid is stored in the memory unit 3, and the SCU 2 monitors the information for a specified time.

A switch for canceling the designated time setting mode is provided on the operation unit 6, and when this switch is released, the SCU 2 notifies the memory unit 3 of this information via the system bus 11, and the memory unit 3 It suffices to delete the information that this function is valid from 3. In this embodiment, normal reception processing is performed when the time designation is released.
