Description

Description: TECHNICAL FIELD The present invention relates to a communication device, and more particularly, to a communication device sharing one line for telephone and data communication. (Prior Art) In recent years, in the information society, facsimile communication devices have become widespread along with miniaturization and price reduction of devices. However, when the frequency of facsimile communication is not so large, a facsimile dedicated to facsimile is newly provided. It is common that a common telephone line is shared with a normally used telephone line by using a switch or the like without drawing a complicated telephone line. In this case, when the telephone mechanism is frequently used as a telephone, and there is a person nearby, the facsimile mechanism does not perform automatic reception, but sets a manual reception state, and switches the connection with the line to the facsimile mechanism only when performing facsimile communication. . When a person is not nearby or when facsimile reception is large, the absence mode is set and facsimile communication is automatically received. Therefore, facsimile communication can be received even during absence. As described above, in the conventional communication device control method, communication is performed by switching the connection to a line to a telephone mechanism or a facsimile mechanism in accordance with the usage status of the communication device. (Problems to be Solved by the Invention) However, in a conventional communication device in which one telephone line is shared by a telephone mechanism and a facsimile mechanism, in an unattended mode, a call from the line is not transmitted. Regardless of whether the other party is a telephone or a facsimile machine, all are in the facsimile automatic reception state, so if the other party is a telephone, not only will the fee be wasted, but also the message cannot be transmitted. Was. (Objects of the Invention) Accordingly, the present invention enables data communication or recording of a message from the other party by appropriately switching the line to the telephone side or the data apparatus side according to the other party, and recording of the message. In some cases, unnecessary recording operations are not performed, thereby realizing the transmission of business requirements and the reduction of waste, and improving the convenience and usability of a communication device that shares one line for telephone and data communication. It is intended to be. (Constitution of the Invention) The present invention relates to a communication device having a home mode and an absent mode to selectively connect a line to a telephone or a data device to perform a telephone call or a facsimile communication. It is equipped with voice recording means for recording voice messages sent from the front. When a call signal from the line is detected, it is determined whether to be in the home mode or the absence mode before connecting to the line. In the absence mode, the ringing period is monitored by the ringing signal. If the telephone does not go off-hook even if the ringing period reaches a preset period, the line is automatically connected to the data device. Side, and after connecting to the line, immediately sends a voice message notifying the absence, and determines whether the other party is a data device or a telephone based on the signal sent through the line If it is determined that the other party is a data device, a predetermined data communication procedure is executed to perform facsimile communication, while if it is determined that the other party is a telephone, a voice message The recording is started after the determination. Further, in the present invention, in the home mode, a call or facsimile communication is performed according to an operation by an operator, or the fact that a voice message is recorded by the voice recording means in the absence mode is stored by a flag or the like, and the home mode is stored. At the time of switching to the mode, the voice message is output (reproduced), and the voice message recorded by the voice recording means is deleted in response to the delete command, for example, when the reproduction stop command is determined to be a delete command and the stop is performed. It is preferred that this be done. (Examples) Hereinafter, the present invention will be specifically described based on examples. 1 to 5 are views showing an embodiment of the present invention.

The CPU 10 controls each unit to execute processing as a memo call, and executes reception processing in the absence mode of the present invention. The ROM 11 stores a processing program as the memo phone 1 and a reception processing program in the absence mode of the present invention, and the RAM 12 is a memory for storing image data. The DCR 13 performs compression / reproduction of image data. The operation port 14 is a port for the error display lamp 6, the communication display lamp 7, the start / stop switch 8, and the mode switch 9. The plotter unit 15 includes a thermal head having a heating element, a platen roller that comes into contact with the thermal head, a step motor that drives the platen roller, and a roll-shaped recording paper that is supplied between the thermal head and the platen roller. The image information read by the scanner unit 16 and the image information sent via the lines L ₁ and L ₂ are recorded on recording paper. The scanner unit 16 includes a light source that projects light onto a document inserted from the document insertion slot 4, an image sensor that receives reflected light from the light source and performs photoelectric conversion, a feed roller that feeds the document, and a step motor that drives the feed roller. While the original inserted from the original insertion slot 4 is fed by a feed roller, light is projected from a light source, and the reflected light is photoelectrically converted by an image sensor. The modem 17 or modulated into a transmittable signal form the image information on the telephone line L _1, L _2, demodulates the signal the sent via the telephone line L _1, L _2. The NCU 18 includes a switching relay 31, an off-hook detection sensor 32, a dial pulse generating relay 33, and the like. The switching relay 31 connects the telephone lines L ₁ and L ₂ to the handset (telephone mechanism) 3 side and the facsimile mechanism (modem 17) side. Switch to. The switching relay 31 has its normally closed position set by the mode switch 9 and is switched by a switching signal from the CPU 10. A photocoupler is used as the off-hook detection sensor 32, which detects an off-hook of the handset 3 and outputs an off-hook signal to the CPU 10 via the I / O port 19. The DTMF detection unit 20 detects a tone signal transmitted through the telephone lines L ₁ and L ₂ , and this tone signal is generated by the other party pressing a predetermined push button according to a voice message from a voice recording / output unit 21 described later. This is a tone signal to be transmitted. The audio recording / output unit 21 is, as shown in FIG.
It has a voice synthesis IC 34 and a voice data storage RAM 35,
The voice data stored in the RAM 35 for storing voice data is input from the handset 3 and transmitted as voice messages from the memo telephone to the telephone lines L ₁ and L ₂ and voice data transmitted as voice messages from the other party through the telephone lines L ₁ and L _2. To memorize. The voice recording / output unit 21 converts the telephone lines L ₁ and L ₂ as voice data voice messages stored in the voice data storage RAM 35 in response to a voice message transmission signal from the CPU 10.
The voice data stored in the voice data storage RAM 35 is output as a voice message from the other party through the speaker 24 according to a reproduction signal from the CPU 10. Next, the operation of the facsimile machine 1 can be selected between the home mode (I) and the absence mode (II) by the mode switch 9, and the operation will be described for each mode. (I) Home Mode When the home mode is selected by the mode switch 9 of the memo telephone 1, the switching relay 31 connects the lines L ₁ and L ₂ to the handset 3 according to a switching signal from the CPU 10. Therefore, when there is ringing through the lines L ₁ and L ₂ , the operator goes off-hook the handset 3 and responds. In this case, if the other party is a telephone, the conversation is continued as it is, and if the other party is a facsimile machine, the operator presses the start / stop switch 8 to start the receiving operation. The off-hook in this case is detected by the off-hook detection sensor 32, and the CPU 10 starts preparing for reception. (II) Absence mode When the absence mode is selected by the mode changeover switch 9 of the memo telephone, the switching relay 31 connects the lines L ₁ and L ₂ to the modem 17 side, that is, the facsimile mechanism side in accordance with a switching instruction from the CPU 10. . Hereinafter, the operation of the memo phone 1 in the absence mode will be described.
This will be described with reference to the flowchart shown in FIG. In addition,
The fourth figure P ₁ to P ₁₆ shows the steps of the flow. When there is ringing through the line (when a ringing tone is detected) (step P ₁ ), it is checked whether or not the mode changeover switch 9 is on the absent mode side (step P ₂ ). judges whether or not the elapsed or a predetermined time rang number (step P _3). If the user is off-hook during this period (step P ₄ ), the operator is at home, and according to the operation of the operator, if the user is not off-hook, a switching signal is output from the CPU 10 to the switching relay 31 and the telephone line L ₁ , the L ₂ switch to modem 17 side (step P _5). Thereafter, the CPU 10 outputs a voice message transmission signal to the voice recording / output unit 21 and
The output unit 21 sends a voice message to the telephone lines L ₁ and L ₂ (step P ₆ ). This voice message is, for example, "This is xx. I am absent right now, please press the dial number 1 and get a message." The voice message is recorded that the other party is absent. When the user desires, a certain operation is urged. Subsequently, a CED (Called Terminal Identification) signal and DIS
It sends a facsimile control signal, such as a (digital identification) signal (step P _7), the other party even when the also the facsimile apparatus even when the phone, and ready for action. Next, a DTMF signal (for example,
Upon receiving the DTMF signal of the push button No. 1 (step P ₈ ), the other party is determined to be a telephone, and the CED signal and DIS
The transmission of signals and the like is stopped and the audio flag is turned on (step P ₉ ), and a recording signal is output to the audio recording / output unit 21 to activate the audio recording / output unit 21 (step P ₁₀ ). The voice message sent from the other party is recorded in the voice recording / output unit 21 (step P
₁₁ ) When the other party goes on-hook and the polarity reversal detection unit 22 detects the polarity reversal of the lines L ₁ and L ₂ (step
P _12), the flow is terminated line as disconnection (step P
₁₃ ). Therefore, in the absence mode, by transmitting a predetermined DTMF signal in accordance with the voice message, the voice message (message) of the caller can be recorded (registered), so that not only the telephone charge is not wasted but also the memo call 1
Convenience and usability can be improved. At this time, when the other party goes on-hook and disconnects the line, the polarity reversal detection unit 22 immediately detects the polarity reversal of the lines L ₁ and L ₂ , and performs this flow, that is, the voice recording / voice recording of the voice message sent from the other party. Since the recording by the output unit 21 is terminated (stopped), useless recording is not continued. On the other hand, in step P _8, when the DTMF signal is not received, DCS (digital command) whether check has been received facsimile control signal from the signal such as the other party (step
P _14), when receiving a facsimile control signal, performs normal facsimile communication procedure (step
P ₁₅ ). Thereafter, the facsimile reception is completed, to open the line the flow ends (step P _13). Step when not receiving a mating facsimile control signal at P _14, CED signal from memo telephone 1, to check whether or not elapsed preset prescribed time as the time for sending the facsimile control signal, such as a DIS signal (step P _16), the step P ₇ until the elapse of the specified time, P
_8, repeated P ₁₄ and step P _16. When the specified time has elapsed, the line is released and the flow ends. When the voice message from the other party is recorded in the voice recording / output unit 21 during the receiving process, the voice message is output from the speaker 24 by the operation described below. That is, as shown in FIG. 5, when the operator switches the mode changeover switch 9 to the home mode side (step S ₁ ), the CPU 10 checks whether the voice flag is on (step S ₁ ).
S _2), the present flow is determined that the voice message is not recorded in the audio recording / output unit 21 when not turned on proceeds to exit to the normal home mode process. This speech flag is flag turned on before a voice message recording in Step P ₉ of the Figure 4. When the audio flag is on, the CPU 10
It determines that a voice message is recorded in the output unit 21 and outputs a playback signal to the voice recording / output unit 21;
It activates the audio recording / output unit 21 to output a voice message from the speaker 24 (Step S _3). The reproduction of the voice message is repeated until the operator presses the start / stop switch 8 (step S ₄ ). When the start / stop switch 8 is pressed, the CPU 10 outputs a stop signal (erase command) to the voice recording / output unit 21. and stop playing the voice message, to erase the recorded content (step S _5). As described above, according to the memo phone 1 of the present embodiment, in the absence mode, it is possible to notify the calling party of the absence by voice and to record the voice message from the other party without waste (recording). ), The telephone charge is not wasted, and the convenience and usability of the memo telephone 1 can be improved. In the case of the present embodiment, recording is performed only when the other party intends to send a voice message, so that waste of memory can be prevented. It goes without saying that the voice message sent to the other party is not limited to the content of the above-mentioned party. Further, a magnetic tape or the like may be used as the audio recording / output unit. Further, the communication device is not limited to the memo telephone, but may be any communication device having both a telephone mechanism and a facsimile mechanism. (Effects) According to the present invention, it is possible to receive a voice message from a telephone even when the user is absent, and to transmit a message, thereby reducing wasteful telephone charges and making one telephone line available. Convenience and usability of a communication device shared between the communication device and the data communication can be improved.
