Abstract

PURPOSE:To attain the transmission of a picture signal corresponding to an original for a required part desired by a user by resending a corresponding picture signal in a storage memory based on retransmission information at the abnormality of communication. CONSTITUTION:A CPU 1 stores a picture signal obtained from the original by a read section into a storage memory 4 and applies the control relating to the retransmission based on a program stored in a nonrewritable area 21 in a main memory 2. Further, the CPU 1 detects a given specific code and stores the retransmission information into the rewritable area 22 of the memory 2. Then the corresponding picture signal in the memory 4 is resent based on the retransmission information of the area 22 at the abnormality of communication. The retransmission information representing which part of the stored picture signal is to be resent is revised externally in such way and the signal is resent based on the retransmission information, then the picture signal of the part desired by the user is sent.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a facsimile machine that has a storage memory for storing image signals and is capable of retransmitting the image signals in the storage memory after a communication error. It is related to the device.

(Prior Art) In this type of conventional facsimile apparatus, when a communication error occurs, retransmission is performed using an image signal stored in a storage memory.

In this case, if the image signals stored in the storage memory are based on, for example, multiple originals, when retransmitting, the image signals corresponding to all of the multiple originals must be retransmitted, or the Whether or not to retransmit the image signal corresponding to the document after the abnormality has occurred is uniquely fixed for each facsimile device.

Therefore, even if you do not resend an extremely important document from the beginning when a communication error occurs, a transmission error may occur if the facsimile machine is to send image signals for originals after the original where the communication error occurred. It was impossible to transmit image signals for originals before the original.

Furthermore, for reasons such as organizing documents, some users may request that all manuscripts be sent after the one in which the communication error occurred when retransmitting them. , there was a risk that they would be forced to do 94 tedious tasks to organize the sent documents.

(Problems to be Solved by the Invention) As described above, with conventional facsimile devices, the image signal to be retransmitted after a communication error is uniquely and fixedly determined for each facsimile device. This was inconvenient because it was not possible to retransmit the data according to the customer's wishes. The present invention has been made in view of the shortcomings of the conventional facsimile apparatus, and its purpose is to retransmit the corresponding image signal in response to an instruction regarding which part of the accumulated image signal is to be retransmitted. An object of the present invention is to provide a facsimile device that performs the following functions.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a storage memory that stores a series of image signals to be transmitted, and a storage memory that stores a series of image signals that are stored in the storage memory during retransmission after a communication error. a retransmission information memory storing retransmission information regarding which part to retransmit; a retransmission information storage means for storing externally given retransmission information in the retransmission information memory; The facsimile apparatus is provided with retransmission means for retransmitting the corresponding image signal in the storage memory based on the retransmission information.

(Function) According to the above configuration, retransmission information can be given from the outside to cause the photometric signal in the storage memory to be retransmitted.
This may take the form of retransmission as desired.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of essential parts of an embodiment of the present invention. In the figure, 1 is the CPU, and the CPU 1 is the main memory 2.
Each part is controlled based on the internal programs and data. Reference numeral 3 indicates a reading section, and the reading section 3 photoelectrically converts an image of an input document to obtain an image signal. The read image signal is stored in the storage memory 4 by the CPU 1.

In addition to the image signals read by the reading section 3, the M product memory 4 also stores image signals sent from the other party's facsimile machine. 5 indicates a recording unit, and the recording unit 5 is CPtJl.
Recording output is performed based on the image signal in the storage memory 4 given under the control of. 6 indicates a panel section. In addition to dial keys and communication keys, the panel section 6 includes various function keys (in this embodiment, M transmission information setting keys 61, 62, 63).
＞ is installed, and the necessary display device is also provided. The retransmission information setting keys 1 are used to set that all input documents should be retransmitted from the beginning, and the retransmission information setting key 62 is used to resend the input document after the communication error occurs. The retransmission information setting key 63 is used to set what should be done, and is used to set that only a specific page should be retransmitted. The main memory 2 has a rewritable area ti (by ROM) 2, as shown by the broken line.
1 and a rewritable area (based on RAM) 22, and the rewritable area 22 has retransmission information setting keys 61 to 61.
Based on the operation of 63, CPt11 captures the corresponding retransmission information. 7 indicates a modem, 8 indicates an NCU, and 9 indicates a line. The modem 7 modulates the image signal to be transmitted and demodulates the image signal to be received, and the NCU 3 performs activation and recovery of the network connected via the line 9. Usually, a facsimile machine includes a function for encoding and compressing an image signal, and conversely, decoding and reducing it, but this is not relevant to this invention and will therefore be omitted.

The CPU 1 of the facsimile machine as described above performs control related to retransmission based on the programs of the flowcharts shown in FIGS. 2 and 3 stored in the non-rewritable area 21 in the main memory 2. Specifically, it operates as follows.

When the power is turned on, initialization is performed and then it is detected whether there is an input (101). If there is an input, the resend notification setting key 61
- 63 is operated or not is detected (102).

When the retransmission information setting keys 61 to 63 on the panel section 6 are operated, a specific code is given to the CPUI.
1 detects this and stores retransmission information corresponding to any one of 61 to 63 in the rewritable area 22 in the main memory 2.
103). Further, if the retransmission information selection keys 61 to 63 are not operated, it is detected whether or not it is a transmission request (by operation of the transmission key) (104), and if it is a transmission request, the process shifts to the transmission operation shown in FIG. However, if it is not a transmission request, the process proceeds to other processing.

In the transmission operation, the CPU 1 controls the NCU 3 to activate the network and send out a corresponding dial signal via the line 9 to call the destination facsimile machine. The other party's facsimile machine responds and sends control signals DIS and NSF based on a predetermined communication control procedure. CP this NSF
tJl detects via the NCU 3 whether or not the recipient facsimile machine is capable of continuing retransmission and receiving (2
01).

Here, when the information that allows continuous reception is detected in the NSF, the CPU 1 uses the retransmission information in the rewritable @ area 22,
At the time of retransmission, information indicating which part of the document is to be retransmitted is included in the control signal NSS and sent to the other party's facsimile machine via the NCU 3, and DO3 and CF are transmitted in the communication control procedure (202). . Next, C
PU1 transmits the image signal in storage memory 4 from the beginning (
203). Then, it detects whether the communication is abnormal or not (
204). This communication error occurs when the other party's facsimile machine
This is detected by checking the number of error lines when decoding the received image signal. In the event of a communication error, after the sender's facsimile device sends an MPS, which is a control signal indicating the end of sending one page, the other party's facsimile device sends an R.
A TP (retransmission request) is sent.

When the CPU 1 detects this, a communication abnormality is detected. Therefore, CPtJl prepares for retransmission by transmitting DO3 and TCP, and reads out the image signal in the storage memory 4 from a predetermined portion based on the retransmission information in the rewritable area 22 and retransmits it (205). That is, if the retransmission information indicates that all of the input originals should be retransmitted from the beginning, the image signals in the storage memory 4 will be retransmitted from the beginning, and the retransmission information will indicate that all of the input originals should be retransmitted from the beginning. If the retransmission information indicates that the original after the original should be retransmitted, the image signals in the storage memory 4 after the original are retransmitted, and if the retransmission information indicates that only a specific page should be retransmitted, the specific The image signal in the storage memory 4 corresponding to only the page is retransmitted. The communication control procedure when image signals are transmitted in this way is the fourth
As shown in the figure.

When communication is performed as described above and the communication abnormality is resolved, the process branches to YES in step 204, and the CPU
Then, the process moves to a communication control procedure for terminating communication (206). That is, the CPU 1 detects via the NCLJ8 that the MCF sent from the other party's facsimile machine has been correctly received, and then sends a DCN and disconnects the line.

On the other hand, if it is detected in step 201 that the other party's facsimile machine does not have a function that allows continuous reception of retransmissions, the CPU 1 transmits the image signal according to the normal communication control procedure (207), and Detect (
208). This detection of a communication abnormality is performed by the CPU 1 using the method described in step 204. When the transmission of the image signal is completed without any communication abnormality, the process moves to step 206.
When CPU1 detects a communication abnormality, it disconnects the line and then
When you call the other party's facsimile machine again and answer,
The corresponding image signal in the storage memory 4 is retransmitted based on the retransmission information in the rewritable area 22 (209). This retransmission is the same as that described in step 205.

As described above, according to this embodiment, the retransmission information setting keys 61 to
63, the mode of retransmission can be freely selected, and moreover, the sending side can perform retransmission with the right to decide.

In this embodiment, once retransmission information is set, it does not return until it is changed next time. However, when the standard mode (for example, retransmission) is determined from the beginning (for example, retransmission information is written in the non-rewritable area 21) and the retransmission information setting keys 61 to 63 are operated when necessary, In the corresponding mode, after the end of communication (step 206), the CP
The retransmission information may be stored in the rewritable area 22 so that U1 becomes the standard mode. In this way,
The mode of retransmission can be changed only in one necessary communication.

Furthermore, in this embodiment, the image signal transmitting side has the right to decide on the mode of retransmission, but the image signal receiving side may have the right to decide. In order to do this, retransmission information is transmitted using NSF in the communication control procedure in FIG.
1 may receive it, store it in the rewritable area 22, and erase it every time the communication is made.

Furthermore, regarding the mode of retransmission, in addition to using a control signal in a communication control procedure, it is also possible to transmit using an MF double signal.

[Effects of the Invention] As explained above, according to the present invention, retransmission information regarding which part of the image signal stored in the storage memory is to be retransmitted can be externally changed, and this retransmission information Since the corresponding image signal in the storage memory is retransmitted based on this, the image signal corresponding to the required portion of the document is transmitted according to the user's wishes.
