Abstract

PROBLEM TO BE SOLVED: To retransmit an image in the original size without bothering an operator of the transmitter and receiver sides by providing a control means that stores image data in the original size to a storage means when reduction is conducted in image data transmission but does not store the image data thereto when the image data are transmitted without reduction. SOLUTION: Information denoting 'B4 size recording enabled' is set to a DIS signal at a receiver side in the case of re-transmission. Thus, in the case that no reduction is conducted, B4 size image data stored in a storage section 5 are transmitted without reduction. when a control section 2 recognizes an opposite terminal is still in the state of receiving only A4 size data only on the basis of the received DIS signal, the reduced data are retransmitted again and storage contents in the storage section 5 are not deleted. In the case of transmission of reduced data, the image data of the original size are left in the storage section 5. Thus, an operator can transmits data of the original size without setting an original again to the facsimile terminal.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a transmission data storage function.

[0002]

2. Description of the Related Art A facsimile apparatus which performs communication via a public telephone line exchanges transmission / reception functions according to a facsimile communication procedure prior to transmission / reception of image data. And
The control unit of the facsimile apparatus on the transmitting side determines the size and linear density of the image data to be transmitted in consideration of the setting of the operator, the document size, and the receiving ability of the receiving side.

For example, when a document of B4 size is set in the facsimile apparatus on the transmitting side, and there is only A4 recording paper in the facsimile apparatus on the receiving side,
The transmitting side performs an automatic reduction process from the B4 size to the A4 size and transmits to the receiving side.

When a B4 recording paper break occurs in a facsimile apparatus capable of setting B4 recording paper and A4 recording paper, the B4 recording paper is sent to the facsimile apparatus.
Facsimile machines that attempt to send originals of the same size
The data is sent after being automatically reduced to the size.
A relatively large size document such as a B4 size document is often not a simple document document but a drawing such as a circuit diagram or a mechanical diagram. When such a document is transmitted in a reduced size, detailed information may be lost.

Therefore, the receiving side operator often replenishes the B4 recording paper and requests the transmitting side operator to resend the same document. In response to the request, the transmitting side operator needs to take out the original again, set it on the facsimile machine, and perform the transmission operation again.

[0006]

As described above, since the conventional facsimile apparatus has the automatic reduction function, the operator on the transmitting side and the operator on the receiving side may be bothered in some cases. There is a problem that.

Accordingly, the present invention provides a facsimile apparatus which performs automatic reduction transmission according to the reception function of the receiving side, and retransmits the original document of the original size without bothering the transmitting side operator and the receiving side operator. It is an object of the present invention to provide a facsimile apparatus capable of performing the following.

[0008]

In a facsimile apparatus according to the present invention, when a reduction process is performed during image data transmission, the image data of the original size is stored in the storage unit, and the transmission is performed without performing the reduction process. It is provided with a control means for not storing the image data when the operation is performed. Therefore, when the partner device returns to a state where it can receive a size that does not shrink, image data of the original size can be easily transmitted using the image data in the storage means.

The control means stores the communication result in the storage means at the end of each communication and displays the communication result on the display unit in response to the request of the operator, and the storage means in response to the designation of the operator. And retransmission means for retransmitting the image data in the image data. According to such a configuration, the operator can easily obtain the information to be retransmitted.

[0010] The retransmitting means may be configured to retransmit to the destination specified by the destination information included in the communication result. According to such a configuration, the operator can start retransmission without inputting the destination telephone number.

The retransmitting means may be configured to retransmit the image data of the document in the storage means specified by the operator. According to such a configuration, even when the image data of each document based on a plurality of communications is stored in the storage unit, the operator can select the relevant document and retransmit the document.

The control means may be configured to include a polling transmission means for transmitting the image data stored in the storage means when receiving the transmission command signal from the partner facsimile machine. According to such a configuration, the original document of the original size can be retransmitted without any operation by the operator.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a facsimile apparatus. In FIG. 1, an operation panel 1 has various keys and a display unit, and transmits key press information to the control unit 2 and displays various information on the display unit in accordance with an instruction from the control unit 2. A document size detection unit 3 using a microswitch or an optical sensor detects the size of a document placed on a document set table (not shown). The reading unit 4 reads the contents of a document and performs binarization processing or the like to generate image data. Further, the reading unit 4 stores the image data in the storage unit 5 according to the instruction of the control unit 5.

The control section 2 controls transmission and reception of facsimile procedure signals and image signals via a communication section 6 including a modem or the like. The received image signal is supplied to the recording unit 7,
The printout is performed by the recording unit 7. The control unit 2 is realized by, for example, a microprocessor.

Next, the transmission process will be described with reference to the flowchart of FIG. 2 and the sequence diagram of FIG. When a document is set on the document set table and an operation for transmission is performed on the operation panel 1, the control unit 2 inputs document size information from the document size detection unit 3. And the reading unit 4
Is given a reading instruction. Then, the reading section 4 reads the contents of the document and performs binarization processing or the like to generate image data (step S1). Then, the image data is stored in the storage unit 5 (step S2). Here, it is assumed that a B4 document is set.

When the reading of the original is completed, the control unit 2 gives a call instruction to the communication unit 6. The communication unit 6 performs a calling process according to the instruction (Step S3). When the receiving-side facsimile apparatus responds, the control unit 2 exchanges the facsimile communication procedure with the receiving-side facsimile apparatus via the communication unit 6 (step S4).

FIG. 3 is a block diagram of the ITU-T T.30. FIG. 3 is a sequence diagram showing an example of a G3 facsimile communication procedure based on G.30. The receiving-side facsimile apparatus sets the DIS in response to the incoming call.
Send a signal. Here, in the facsimile apparatus on the receiving side, it is assumed that the B4 recording paper has run out and only the A4 recording paper has been set. Then, information indicating “A4 recordable” is set in the DIS signal.

When the control unit 2 receives the DIS signal and knows that the facsimile apparatus on the receiving side can receive only the A4 size, the control unit 2 decides to reduce the image data in the storage unit 5 and transmit it (step). S5, S6). Therefore, DC
Set information indicating "A4 original" in the S signal,
Thereafter, the image data in the storage unit 5 is reduced and the image signal (PI
X). The reduction is realized by, for example, thinning out image data by the control unit 2.

If the read original is A4 size, the original is transmitted without being reduced (steps S5 and S7). It should be noted that, even if it is transmitted as it is, necessary encoding processing and the like have been performed. If the transmission is performed without reducing the size, the transmission is completed when the transmission is completed.
The image data in the storage unit 5 is deleted (step S8), but when the reduced transmission is performed, the image data in the storage unit 5 is not deleted.

When the transmission is completed, the control section 2 sets the transmission time and information for specifying the destination in the storage section 5 (step S9). By the above processing, the operator does not recognize that the reduced transmission has been performed, but the image data remains in the storage unit 5 of the facsimile apparatus together with the communication record.

The user on the receiving side will have a reduced recorded image. If the recorded image is unclear as a result of the reduction processing, the user replenishes the B4 recording paper and requests the operator on the transmitting side to retransmit it by telephone or the like.

Next, the processing at the time of retransmission will be described with reference to the flowchart of FIG. 4 and the sequence diagram of FIG. Since a facsimile apparatus generally has a communication record display function, an operator on the transmitting side first performs an operation for displaying a communication record from the operation panel 1. The control unit 2 reads the communication record from the storage unit 5 according to the operation. Then, the communication record is displayed on the display unit of the operation panel 1 (step S11). When there are many communication records, for example, the communication records are displayed sequentially.

If the operator finds a communication record corresponding to the request of the user on the receiving side, he specifies retransmission of the transmission corresponding to the communication record (step S12). The retransmission is specified, for example, by specifying the serial number assigned to each communication record. If retransmission is specified,
The control unit 2 calls a destination that can be identified from the corresponding communication record (step S13), and thereafter performs the same processing as the processing of steps S4 to S9 in the flowchart of FIG. 2 (steps S14 to S19). And perform a retransmission. That is, the image data stored in the storage unit 5 is
Send to destination.

At the time of retransmission, as shown in the sequence diagram of FIG. 5, information indicating "B4 recordable" is set in the DIS signal on the receiving side. Therefore, step S
In the determination of 15, it is determined that no reduction is performed, and the B4 image data stored in the storage unit 5 is transmitted as it is. Here, if the control unit 2 recognizes from the received DIS signal that the partner device is still in a state where it can only receive A4, it performs reduced transmission again and does not delete the storage content in the storage unit 5.

As described above, in this embodiment, when reduced transmission is performed, image data of the original size remains in the storage unit 5. Therefore, the operator can transmit a document of the original size without resetting the document. In addition,
Since the image data is stored in the storage unit 5 only when the reduced transmission is performed, the storage capacity is not wasted.

In addition, the communication record is displayed at the time of retransmission, and the operator can specify retransmission by specifying the communication record. Therefore, at the time of retransmission, it is troublesome to specify the telephone number of the destination again. Can be omitted. further,
Since the communication record is displayed, if the image data of each document based on a plurality of communication is stored,
The corresponding document can be easily selected.

In this embodiment, the case where the size is reduced from B4 size to A4 size is taken as an example. However, the present invention can be similarly applied to a case where a reduction process for other sizes is performed.

In this embodiment, the description has been given of the memory transmission in which the image data is stored in the storage section 5 before calling, but the present invention is also applicable to the case where the direct transmission without storing the image data is designated in advance. Can be applied. In this case, when the direct transmission is specified, the document reading is started, for example, after receiving the CFR signal. When it is not necessary to perform the reduced transmission, the image data from the reading unit 4 is transmitted as it is. When the reduction process needs to be performed, the image data from the reading unit 4 is temporarily stored in the storage unit 5, and the control unit 2 reads out the image data from the storage unit 5, performs the reduction process, and transmits the image data.

In the above embodiment, retransmission is performed at the request of the user on the receiving side, but retransmission can be performed by polling transmission. For example, the control unit 2
The image data stored in the storage unit 5 after the reduction transmission is performed is managed as the image data of the document stored for the polling transmission.

The user on the receiving side makes a call to the facsimile machine on the transmitting side instead of requesting the operator on the transmitting side to retransmit by telephone or the like. When the facsimile machine on the transmitting side receives a call, as shown in FIG. 6, the control unit 2 performs control for sending out a DIS signal. In this case, the DIS signal includes information of "with transmission function". . Then, the receiving-side facsimile apparatus that has received such a DIS signal,
A TC (digital transmission command) signal is transmitted. The control unit 2 of the facsimile apparatus on the transmitting side performs control for transmitting the DCS signal in response to the reception of the DTC signal, and then performs the processing from step S15 shown in the flowchart of FIG.

Therefore, the original document of the original size can be retransmitted without any operation by the operator on the transmitting side.
Therefore, by using the polling transmission / reception, the trouble of the operator on the transmission side at the time of retransmission can be further reduced. Even if the image data of a plurality of documents exist in the storage unit 5, since the transmission destination can be specified from the communication record of the document, only the image data of the document desired by the facsimile apparatus which has issued the polling reception request is stored. It can be sent to the facsimile machine.

The control unit 2 manages the image data stored in the storage unit 5 after the reduced transmission has been performed as a document for polling transmission, and controls the operator as described in the first embodiment. May be managed as a document to be retransmitted in accordance with the specification of. That is, the control unit 2 transmits the image data of the specified document in the storage unit 5 when retransmission is specified by the operator, and when the polling reception request is received from the facsimile apparatus on the receiving side, the control unit 2 The image data of the corresponding document in 5 is transmitted.

[0033]

As described above, according to the present invention, when the facsimile apparatus performs the reduction processing at the time of transmitting image data, the image data of the original size is stored in the storage means and the reduction processing is performed. When the original is sent without being sent, the original size of the original document can be retransmitted without bothering the transmitting and receiving operators. There is an effect that can be done.
