Description

TECHNICAL FIELD The present invention relates to a communication device capable of making a call or data communication.

[Prior Art] In a normal communication device of this type, such as an answering machine or a facsimile device, if the automatic reception mode is set,
It only automatically receives transmissions from arbitrary destinations and records the received data on recording tape or recording paper, and does not have a function of selecting destinations to receive.

In this type of facsimile machine, for example, when the automatic reception mode is set and the transmission mode is set in the facsimile machine in the polling mode, the group ID matches or the telephone number matches or the ID and the telephone number are matched. Only when they match, the receiving mode is switched from the receiving mode to the sending mode and the original is only transmitted. In the automatic receiving mode, when the calling party receives a call, the receiving party receives the called party. At present, it is not considered at all to select whether or not to use the information such as an ID registered in advance.

[Problems to be Solved by the Invention] Therefore, in view of the above points, an object of the present invention is to determine whether a communication partner who has transmitted a procedure signal in hope of automatic data communication is a predetermined communication partner. Accordingly, it is another object of the present invention to provide a communication device that enables predetermined data communication to be automatically executed or data communication to be manually executed after making a call.

[Means for Solving Problems] In order to achieve such an object, a communication device according to the present invention includes a data communication means for performing data communication or a connecting means for connecting a call means for making a call to a communication line, and a data means. Whether a key for instructing the execution of communication, a ringing means for generating a ringing tone, and a procedure signal received by the data communication means include data indicating that the communication partner is a predetermined partner In response, the data communication means is controlled to execute predetermined data communication with the communication partner, or
Alternatively, the data communication means is controlled to return a procedure signal for generating a ringing tone on the communication partner side that has transmitted the procedure signal, and the ringing means is controlled to generate a ringing tone on the own station side. And a control means, wherein the control means performs the predetermined data communication with the communication partner when the key is operated during a call by the call means after the ringing tone is generated. It controls the means.

[Operation] In the present invention, depending on whether or not the received procedure signal includes data indicating that the communication partner is a predetermined partner, a ringing tone is generated to the communication partner who has transmitted the procedure signal. Since it is configured to send back the procedure signal for making it possible, even if the communication partner who has sent out the procedure signal in hope of automatic data communication cannot automatically determine whether or not to execute the data communication, It becomes possible to perform data communication manually after making a call.

Reference numeral 130 is a power supply circuit for supplying various power supplies to each part of the circuit of this embodiment.

Here, the case of reception will be described.

First, the calling side goes through steps S31 and S32 in FIG.
Dial using your telephone or an alternative method. As a result, a ring tone is transmitted from the exchange to the called side via the telephone line 110. The called side detects this ring tone by the network control circuit 100 and sends it to the main control circuit 60.

When detecting the ring tone, the main control circuit 60 enters the control procedure shown in the flowcharts of FIGS. 2 and 3.

That is, when the ring tone is detected in step S1, it is then determined in step S2 whether or not this communication device is operating, for example, a copying operation.
Here, if it is not in operation, the process proceeds to step S3 to determine whether it is the automatic reception mode or the manual reception mode.

If in manual reception mode, move to step S4
Ring 120 bells. The ringing is on the called party's telephone 1
Continue until you pick up 20 handsets or the caller stops calling and the line is disconnected.

On the other hand, in the automatic reception mode, the process proceeds to step S5,
Here, the main control circuit 60 activates the power supply circuit 130.

By activating the power supply in this manner, the state of the switch 51 of the operation panel 50 is read according to the instruction of the control program circuit 70 and temporarily stored in the storage circuit 80.

In this storage circuit 80, it is assumed that the data of the other party who receives the reception such as the other party's ID or telephone number is registered. The number of registrations is limited according to the storage capacity of the storage circuit 80.

As soon as such an apparatus is initially prepared, the procedure signal is converted between the transmitter / receiver via the telephone line 110 from the modulation / demodulation circuit 90 and the network control circuit 100, and then the message is transmitted.

Here, exchange of procedure signals will be described with reference to FIGS.

In step S6 shown in FIG. 2, first, in the case of automatic reception, a called station identification signal CED is transmitted as a response signal, and subsequently in step S7, a nonstandard function (including ID etc.) is included as a function identification signal of the receiver. ) An identification signal NSF, a called terminal identification signal (telephone number) CSI, and a digital identification signal DIS are sent to the calling side.

In order to respond to it, the calling side sends out the dialed number, and then waits for a response from the other side.
If no received signal is detected at step S3
Go to 4 and set the soft timer for time T1 here.
If there is no response from the calling side during the time T1, it is determined that T1 time is up in step S35 and the process proceeds to step S36, where the line is disconnected.

On the other hand, when the calling side receives any signal, the process proceeds from step S33 to S37. Then, when NSF, CSI, DIS on the called side is detected in step S37, a response signal is transmitted in the next step S38.

That is, the calling side responds with a non-standard function command signal (NSF including ID etc.) as a signal which is a mode setting command.
Response signal) NSC and transmission terminal identification signal (telephone number) TSI
And a digital transmission command signal (DIS response signal) DCS.

At the called side, in step S8, these NSC, TSI, DCS
It is determined whether or not a signal is detected, and when it is detected, the process proceeds to the sequential steps S9 to S10, and when the ID of the NSC signal and the ID registered in advance in the called device are obtained, or , When the telephone number in the TSI signal matches the telephone number registered in the called device, step S12
And set the receiver mode according to the DCS signal command.

The calling side proceeds to step S39, where the phase / training signal is transmitted.

On the called side, in step S12, phase matching and training are performed based on the sent phase / training signal, and in next step S13, reception preparation confirmation signal C
After sending FR, it goes to the message receiving routine S14.

When the calling side detects such a signal CFR, it proceeds from step S40 to the message transmission routine S41.

Below that, the communication operation shall be performed in accordance with the customary T30 procedure.

The above is an example of the case where the NSC signal or TSI signal matches the ID or telephone number registered in the called side device, but unlike this, even if the called side detects the NSC TIS DCS signal twice. , ID, etc. or telephone numbers do not match, the process proceeds from step S11 to step S15 and the procedure interruption signal PRI EOP
Is transmitted to the calling side, and the process proceeds to step S16 in the flowchart of FIG.

When the calling side detects such a PRI EOP signal, it proceeds to step S43 in the flowchart of FIG.

In step S43, a pseudo-bell sound close to that of the telephone is sounded to call the operator, while in step S44, the T1 timer is reset, and the next step S
At 45, the second soft timer of time T2 is newly set.

The time T2 is monitored in step S46, and if the operator does not pick up the receiver within the predetermined time, the process proceeds to step S54 to disconnect the line. This returns the transmitter to the initial state.

On the other hand, before the time T2 expires, the operator picks up the handset and waits for the other party to come out. If the opponent comes out,
After steps S47 to S49, talk with the other party and then step S5.
At 0, the receiver searches for the reception key. If the receive key is pressed, the send key is turned on in step S51.

Then, the DIS signal is detected in step S52. Here, when the DIS signal is detected, the process proceeds to step S53 and DC
After sending the S signal, the process returns to step S39 in FIG.

Hereinafter, the message is transmitted by following the above procedure.

On the other hand, in step S48 (FIG. 5), if the other party does not come out, or if the user talks with the other party and the reception is rejected in step S50, the process proceeds to step S54, and the receiver is placed. Here, the line is disconnected and the initial state is restored.

Next, the procedure (FIG. 3) after step S16 on the called side will be described.

In step S16, a pseudo bell is sounded in the same manner as the calling side to call the operator, while in step S17, a timer is set, and in step S18, it is determined whether or not the timer counts up, and the call is received within the predetermined time. If the operator on the side does not come out, the process of the line disconnection S25 similar to step S54 on the calling side is performed.

Local, called operator picks up the handset (step
S19), when the other party comes out (step S20: YES), conversation is performed through steps S19 to S21, and if it is necessary to receive, the reception key is pressed in step S22. Then, in step S23, the DIS signal is transmitted, in the next step S24, DCS detection is performed, and the process returns to step S12 in FIG.
Receive a message.

The message signal is demodulated by the demodulation circuit in the modulation / demodulation circuit 90, and is further temporarily stored in the memory circuit 80 by the main control circuit 60. When the received data for one line is complete, the received data is transferred to the recording head drive circuit 41, and the recording head 32 reproduces the message on the recording paper 31.

By repeatedly executing the above operation, it is possible to record the successive lines and receive and record one message.

If the sender has a large number of originals to send, such as multiple sheets, the reel
It can be repeatedly received from 34 until the recording paper 31 runs out.

When the communication device of the present embodiment is a transmitter, the telephone 120 calls the receiver on the other side, and procedure signals are exchanged between the transmitter and the receiver as in the case of reception under the control of the main control circuit 60. Then, as soon as the preparation for transmission is completed, the data read by the document reading unit 10 is stored in the storage circuit 80 through the binarizing circuit 21 and the encoding circuit 22 in the reading control circuit 20 and under the control of the main control circuit 60. Read the data. This data is modulated by the modulation / demodulation circuit 90, data is repeatedly transmitted from the network control circuit 100 to the transmitter side via the telephone line 110, and the message is reproduced.

By repeating the above process, it is possible to transmit a plurality of originals.

As described above, according to the present embodiment, unlike a communication device such as a conventional facsimile device that indiscriminately receives a transmitted original document, by registering a recipient who receives the reception in advance, In addition to being able to limit the destination, on the contrary, even if it is not registered, it is possible to operate like manual reception mode by ringing a pseudo bell sound, and you should talk and receive using the telephone with the other party It can be received by a manual reception operation by determining whether or not the contents are included. Therefore, according to the present embodiment, it is possible to reduce wasteful operation time by avoiding unnecessary reception.

Therefore, the present embodiment can exert the following effects.

(1) Since the receiver side can select the other party to receive, unnecessary information (for example, direct mail) can be prevented from being received.

(2) Useless use of recording paper is eliminated.

(3) Useless operating time is eliminated, and the telephone or communication device can be effectively used.

(4) With the automatic reception mode set, even if the ID or telephone number do not match, the operator can perform the same processing as manual reception by ringing a pseudo bell, so it is necessary. You can prevent the failure to receive information.

Although the present embodiment has been described by taking the case of a facsimile machine as an example, the present invention is not limited to a facsimile machine and can be implemented in any communication device such as a telex.

[Effect] As described above, according to the present invention, the communication that has transmitted the procedure signal is determined depending on whether or not the received procedure signal includes data indicating that the communication partner is a predetermined party. Since it is configured to send back a procedure signal to generate a ringing tone to the other party, it is automatically determined whether the communication party who has sent the procedure signal in hope of automatic data communication is a party to execute data communication. Even when it is not possible to make a decision, it is possible to obtain a special effect that it becomes possible to manually perform data communication after making a call.
