Abstract

PURPOSE:To send a picture to an operator of a communication opposite station surely without giving a trouble by sending the picture of a message to the communication opposite station when no reserved talking is applied by a talking reservation function. CONSTITUTION:If the talking reservation is applied during the reception of picture and no talking is realized, a transmission station is called automatically after the end of communication to send the of the message picture representing the desire of talking. An MPU 3 reads a message of desired communication from a ROM 1 and a telephone number of its own station from a RAM 2 and reads the date from a timer and sends them to a line 10 via a network controller 8. Thus, the picture of the message desired for talking is recorded on recording paper together with a picture of telephone number and date in an equipment of the transmission station. Thus, the desired talking is sent surely to the operator of the transmission station.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an image communication device, and in particular, an image communication device equipped with a telephone,
The present invention relates to an image communication device having a so-called call reservation function for reserving a call with a communication partner using the telephone during image communication.

[Prior Art J] This type of image communication device includes a facsimile device having a call reservation function. This is because, in facsimile communications, there are many cases in which the operator uses the telephone attached to the facsimile device to speak to the operator of the other party's device after the end of the image communication.

FIG. 5 explains the communication procedure when reserving a call using a conventional facsimile machine having a call reservation function, and shows an example of the procedure when the operator of the receiving device desires to reserve a call. Note that Recommendation T is used for Group 3 equipment according to the standards of CCITT (International Telegraph and Telephone Consultative Committee).
Communication shall be performed using a communication control procedure that complies with 30.

First, a Dis (digital identification) signal that informs the device's functions, a DOS (digital command) signal that instructs the desired mode of communication, a training signal for the high-speed modem that transmits the image signal, and a TCF (training check) that confirms the training. The image signal is transmitted from the transmitting side to the receiving side after exchanging a signal, a CF'R (reception preparation confirmation) signal indicating that the preparation after reception is completed, and the like.

Then, when the receiving side operator operates the operation key for communication reservation provided on the operating section of the receiving side device at the timing indicated by symbol a while receiving the image signal, the receiving side device indicates the end of the image signal. At the time when the EOP (procedure end) signal shown in FIG.

In response to this, the transmitting device immediately starts calling the operator at timing C, and stops calling when the operator responds by operating the telephone off-hook at timing C.

Next, as a response to the PiP signal, the transmitting device notifies that the image signal for one page has ended and will return to the beginning of phase B, and also requests the operator's intervention.
- Sends an EOP (procedure interruption) signal, and then switches the line to the attached telephone at the timing of code d.

On the other hand, when the receiving device receives the PRi-E PO double signal, it starts calling the operator, stops the calling in response to the operator's response similar to the case of the sending device described above, and then transmits the PiP signal. At the timing indicated by symbol e, the line is switched to the attached telephone set, thereby enabling communication between the two operators.

[Problems to be Solved by the Invention] However, in the procedure for making a call reservation as described above, if the operator on the transmitting side is absent and there is no response even after the transmitting side device calls the operator for a predetermined period of time, The communication is terminated, and the receiving operator's intention to talk is not conveyed to the transmitting operator at all, and the communication is terminated.

For this reason, the operator on the receiving side has to contact the sending side again after the communication is completed, which is a problem in that it takes time and effort.

This problem is common to other image communication devices having a call reservation function.

[Means for Solving the Problems] In order to solve the above-mentioned problems, according to the present invention, a telephone is attached, and a call reservation function is provided for reserving a call between the telephone and the communication partner station during image communication. means for storing a message indicating a desire to make a call using the telephone; and control for transmitting an image of the message to a communication partner station if the call reserved by the call reservation function is not made. We have provided means.

[Operation] According to such a configuration, if a call reserved by the call reservation function is not made, an image of a message requesting a call is sent to the communication partner station. Therefore, the desire to make a call is reliably communicated to the operator of the communication partner station, and the operator of the image communication device does not need to contact the communication partner station, which saves time and effort.

[Example] Hereinafter, details of embodiments of the present invention will be described.

Here, a facsimile device equipped with a call reservation function is used as an example, and it is assumed that this device is a Group 3 device according to the CCITT standard and performs communication using a communication control procedure conforming to Recommendations T and 30. In the operation description, the communication control signals that have already been described in the description of the conventional technology will be indicated by abbreviations, and the functional description thereof will be omitted.

FIG. 1 schematically shows the overall configuration of a facsimile apparatus according to this embodiment, and the hardware of this configuration is almost the same as a conventionally known facsimile apparatus having a call reservation function.

Reference numeral 3 also indicates an MPU (-' microprocessor) that controls the whole, and a ROM (read only memory) 1.
and RAM (random access memory) 2. In addition to the control program and various fixed data necessary for control, the ROM 1 stores a character code for a message indicating that the communication partner desires to make a call using the attached telephone. Further, the RAM 2 is used to temporarily store processing data such as image data, and the telephone number of the communication partner station is also temporarily stored here. Further, the telephone number of the own station is also stored in the RAMZ, and this data is of course configured so as not to be volatile.

On the other hand, an image data generator 5 for converting character codes into image data is connected to the MPU 3, and at the subsequent stage, codes and codes for encoding and decoding the image data are connected.
The decoding station 6 is connected to a transmission section 7 that modulates and demodulates image signals, and further connected thereto is a network control device 8 that switches the line 10 between the facsimile machine side and the attached telephone 9 side. It is assumed that the P control device 8 has an automatic calling function that automatically calls the communication partner station.

Also connected to the MPU 3 is an operation section 4 in which various operator keys are arranged for the operator of the facsimile machine to input various operations. A call reservation key 4a, which is an operator's key for issuing commands, is provided along with other input keys (not shown).

In addition, it goes without saying that the MPU 3 is connected to a reading section for reading an image of a transmitted document and a recording section for recording a received image, but these are not shown in the drawing.

With such a configuration, at the time of reception, the image signal received from the line 10 via the network control device 8 is demodulated by the transmission section 7, decoded into image data by the encoder and decoder 6, and the image signal corresponding to this image data is demodulated by the transmission section 7. Image power (sequentially recorded in the recording section under the control of the MPU 3. Also, at the time of transmission, the image data of the transmitted document is read in the reading section, and this data is encoded and recorded in the decoder 6.
The signal is then encoded by the transmission section 7, modulated into an image signal, and sent to the line 10 via the network control device 8.

Next, operations related to call reservation will be explained using the device of this embodiment as the receiving side with reference to FIGS. 2 and 3. Note that FIG. 2 shows the control procedure related to the call reservation at the time of reception by the MPU 3 in FIG. 1, and FIG. 3 shows the communication procedure when the call reserved by the call reservation function is not made. There is.

First, in step SL of FIG. 2, the MPU 3 performs a known pre-communication procedure by exchanging DiS signals, DC3C12 training signals, etc. with the other transmitting station as shown in FIG. 3, and then receives one page of images in step S2. During this procedure, the TSi (transmitting station identification) from the transmitting station must be
The telephone number of the transmitting station sent by signal is stored in RAM2.

When the reception of the image of one page is completed, in step S3, it is checked whether or not a call reservation has been made by inputting the call reservation key 4a of the operation unit 4 at the timing indicated by reference numeral a in FIG. 3 while the image is being received. Step S if
In step 4, the PiP signal mentioned above is transmitted to the transmitting station. As a result, in the transmitting station device, the operator is called for a certain period of time from the timing indicated by symbol A to the timing indicated by symbol C' in FIG.

Next, in step S5, it is determined whether or not the operator of the transmitting station has responded to the call within the above-mentioned predetermined time using PR1-E from the transmitting station.
The presence or absence of an OP signal is checked, and if there is a response, a call is made in the same manner as in the case of the prior art.

Further, if the operator is absent and there is no response and the call is not made, the fact that the call was not realized is stored in the RAM 2 in step S6, and the process proceeds to the next step S8. If not, the process branches to step S7, performs the normal post-procedure after receiving one page of images, and then jumps to step S8.

Next, in step S8, whether or not all images have been received is determined.
That is, it is checked based on the EOP signal from the transmitting side whether or not the image of the next page has been received, and if there is a primary page, the process returns to the previous procedure in that case and repeats the steps from step 52 onwards.

In addition, if the reception of all images is completed, step S9 is set to 1.
Then, it is checked from the memory in RAM 2 whether or not the call was realized. If it is read out that the communication has not been realized, the communication is terminated by disconnecting the line 10 at the timing f in FIG. , waits for a predetermined time in step S11. Thereafter, in step S12, a call is automatically made to the transmitting station, and an image of a message indicating that a call is desired, stored in the ROMI, is transmitted.

To explain the details of the operation in step S12, the MPU
3 first reads the telephone number of the transmitting station from the RAM 2, and thereby causes the network control device 8 to automatically make a call at the timing g in FIG. When the call is connected again to the other party, Di
A pre-transmission procedure is performed by exchanging S signals, DO5 signals, and training signals, and then the MPU 3 transmits an image of the message 11 for which a call is desired to the transmitting station, together with an image of the own station's telephone number, date, etc. This transmission begins when MPU3 sends message 11 requesting communication from ROMI.
, reads the telephone number of the own station from the RAM 2, reads the date of the day from a timer (not shown), converts each code into image data by the image data generator 5, and encodes it by the encoder and decoder 6. , furthermore, the electric transmission section 7
This is done by modulating the image signal into an image signal and transmitting it to the line 10 via the network control device 8.

After transmitting the message, the MPU 3 performs known post-procedures by exchanging EOP signals, MCF signals, etc., transmits a DCN signal, disconnects the line IO, and ends communication.

Note that if it is determined in Step S9 that a telephone conversation is being made, the control is immediately terminated.

As described above, according to the present embodiment, if a call reservation is made during image reception and the call is not realized, the destination transmitting station is automatically called after the communication ends, and a message indicating that the call is desired is made. Send the image of message 11.

As a result, in the device of the previous transmitting station, the image of the message 11 that was sent requesting a call is recorded on the recording paper 14 together with the image of the telephone number 12 and the date 13, as shown in FIG. 4, for example.

Therefore, the desire to make a call is reliably communicated to the operator of the destination transmitting station.

The operator of the device of this embodiment does not need to contact the operator of the previous transmitting station, which saves time and effort.

It goes without saying that the device of this embodiment performs the same operation when a call reservation is made while transmitting an image as the transmitter.

It goes without saying that the configuration related to call reservation as described above is not limited to facsimile machines, but can be similarly applied to other image communication devices having a call reservation function.

[Effects] As is clear from the above description, according to the present invention, an image communication device is provided with a telephone and has a call reservation function for reserving a call with the communication partner station using the telephone during image communication. , a means for storing a message indicating a desire to make a call using the telephone, and a control means for transmitting an image of the message to the communication partner station if the call reserved by the call reservation function is not made.

An excellent effect can be obtained in that when a call reserved by a call reservation function is not made, the desire to make a call can be reliably communicated to the operator at the communication partner station without requiring the operator any effort.
