The present invention relates to a voice and image transmission device for transmitting and receiving voice and image information (for example, handwritten text, a handbook menu, a picture, a picture, a table, a text, etc.).

In general, a telephone for transmitting and receiving voice information includes a handset and a signal processing device for transmitting and receiving voice over wired or wireless, and a fax mill for transmitting and receiving image information includes an image transmitting / receiving device and a printing device.

In the facsimile, such image information is scanned by a transmitting apparatus and transmitted through a series of signal roll communication links, which are reconstructed as original images by the receiving apparatus and printed onto a recording medium by optical, thermal, or magnetic printing means. Is played on.

However, the telephone and the facsimile as described above are constituted by separate and independent communication devices, and thus, there is a problem in that voice and video cannot be simultaneously transmitted and received in one device. That is, when the voice information that can be expressed orally and image information that must be expressed in text, diagrams, pictures, and pictures must be exchanged at the same time, information exchange cannot be performed smoothly. In order to solve these problems, a combined fax machine having a telephone function added to the facsimile machine has been developed and used. However, since the facsimile function and the telephone function are simply combined, the above problem cannot be solved ultimately.

Although transmission and reception were possible, it was impossible to return to the original telephone function after the transmission and reception of the image information was completed. In other words, if the voice information needs to be exchanged while transmitting / receiving image information using the facsimile function, the telephone-facsimile machine stops exchanging image information transmitted / received, that is, the online state of the communication line for transmitting / receiving image information is offline. After that, I had to select the phone function and talk. Therefore, there is a problem in the telephone combined fax that it is not possible to exchange voice information without interruption of a communication line online state while exchanging image information.

The operation and operation of the audio and image transmission apparatus according to the present invention configured as described above will be described in detail with reference to FIGS. 1 to 3.

First, the audio and image transmitting apparatus 100 according to the present invention receives the contract signal (for example, DTMF tone signal) generated by the telephone function selected by the telephone unit 1 or the menu selection unit 12. When the side mode switching unit 32 is remotely controlled, and the functions displayed on the menu selection unit 12 are selected by the input pen 7, an associated additional function corresponding to the function is placed on a predetermined portion of the monitor 6. When the relevant additional function displayed on the monitor 6 is selected with the input pen 7, the corresponding operation is performed.

An embodiment in the case of transmitting and receiving image information while making a telephone call performed by the present invention will be described below with reference to FIG. 3 (a).

First, when the telephone menu displayed on the icon menu selection unit 12 is selected by the input pen 7 or other contact member, the icon menu selection processing unit 36 is operated, and the monitor is operated by the operation of the processing unit 36. A predetermined button (6) displays a dial button. At this time, if the telephone number of the receiver side to be called using the input pen 7 is selected, the tablet 21 of the monitor 6 recognizes the selected telephone number, and the tablet processing unit 24, namely A / The D converter converts the phone number so that the microcontroller 40 can recognize it. When the microcontroller 40 receives the output signal of the A / D converter 24 corresponding to the telephone number, the microcontroller 40 controls the relay of the mode switching unit 32 so that the demodulation unit 26 is connected to the communication line. And a dual tone multiple frequency (DTMF) tone signal corresponding to the telephone number is generated in the modulation / modulator unit 26. When the DTMF tone signal corresponding to the recipient's telephone number is generated and transmitted by the modulation / demodulation unit 26, a telephone call is possible (steps 30 and 34).

If, in step 30, the telephone menu of the icon menu selection unit 12 is not selected, the handset 2, 3 of the telephone unit 1 is picked up and the dial button 4 corresponding to the telephone number of the receiver side is selected. A telephone call can be made (step 32). At this time as well, the DTMF tone signal corresponding to the telephone number is generated.

When the telephone call is enabled through the above process, the call is made as in step 36. There are two methods of calling. That is, if the recipient's telephone number is selected on the tablet 21, the call can be made through the microphone 9 and the speaker 11, and the recipient's telephone number is selected by the dial button 4 of the telephone unit 1. If so, you can talk through your usual handsets (2, 3). In addition, it will be apparent to those skilled in the art that the call may be made through the handsets 2 and 3 during the call through the microphone 9 and the speaker 11, and vice versa. The contents of the call through the microphone 9 and the speaker 11 are signal-processed by the modulation / demodulation unit 26 and are preferably transmitted and received.

If image information exchange is necessary as in step 38 during a telephone call as in step 36, the input pen 7 is used to select an image sending menu on the tablet 21 (step 42). When the image transmission menu on the tablet 21 is selected by the input pen 7, the tablet 21 recognizes this, and the tablet processing unit 24 processes the recognized signal as described above. The signal processed by the tablet processing unit 24 is input to the microcontroller 40 to perform a predetermined control to perform the operation related to the image transmission (step 44). That is, the microcontroller 40 determines whether the menu recognized on the tablet 21 is a menu for image transmission. If it is determined that the menu is for image transmission, the microcontroller 40 performs the following related control operation and determines that the image is not image transmission. If so, perform the function of the menu or continue talking (step 40). When the microcontroller 40 determines the image transmission menu, it controls the mode switching unit 32 (relay) so that predetermined image information is transmitted and received through the trunk line L (step 46). That is, the microcontroller 40 modulates and demodulates a predetermined contract signal (e.g., DTMF tone A signal) after the trunk line L is connected to the telephone unit 1, and then connected to the modulation / demodulation unit 26. To be generated in section 26 (step 48). Here, the role of the agreement signal is for mode switching of the transmitting and receiving side transmission apparatus. That is, a predetermined contract signal is generated and the mode can be switched when received (for example, switching from the audio mode to the image mode).

When the predetermined agreement signal is generated in the modulation and demodulation unit 26 as described above, the microcontroller 40 transmits the agreement signal (hereinafter referred to as DTMF tone A signal) to the image information receiving side through the trunk line L. Be sure to When the receiver side transmitting apparatus 100 receives the DTMF tone A signal, the agreement signal receiver 39 detects the DTMF tone A signal and inputs it to the microcontroller 40. When the microcontroller 40 receives the detected DTMF tone A signal, the relay contact of the mode switching unit 32 is switched so that image information can be received through the trunk line L (step 50). That is, when the trunk line L is connected to the telephone unit 1, the relay contact of the mode switching unit 32 is switched to connect the trunk line L to the modulation and demodulation unit 26 so that image information can be received. As described above, when the mode switching unit 32 is switched and the trunk line L is connected to the modulation / demodulator 26, image information is transmitted and received through the modulation / demodulator 26. Here, the transmission and reception of the image information is transmitted and received according to a predetermined image transmission / reception protocol (for example, G3-FAX protocol) (step 52). Therefore, when the image transmission on the image transmission side is finished, a predetermined image transmission end signal is generated in accordance with the protocol and transmitted to the reception side transmission apparatus 100. Upon reception and recognition of the image transmission end signal by the receiving side transmitting apparatus, a predetermined confirmation signal indicating that the image transmission ending signal has been received is transmitted to the transmitting side autonomous according to the protocol, and accordingly, the microcontroller 40 relays ( 32, the contact point is switched so that the trunk line L is connected to the telephone section 1 (receive side). When the transmitting transmitter receives the acknowledgment signal transmitted from the receiving transmitter, the microcontroller 1 controls the relay 32 as in the receiving transmitter, so that the trunk line L is connected to the telephone unit 5. The contact is switched so as to be connected to the phone so as to enable a telephone call (steps 52, 54, 56). Therefore, it is possible to selectively transmit and receive audio and image information as necessary in the online state of one communication line.

In addition, as another embodiment of the present invention, the operation and operation when the receiving side transmission apparatus is in the auto-response mode will be described with reference to FIG.

First, a ring count value must be set in an environment setting menu provided in the icon menu selection unit 12. If a ring count value is not set in the configuration menu, the ring count value is preferably set in the menu. This is for the recognition of the auto answer mode state in the voice and image transmission apparatus.

In this state, when the transmitting transmitter transmits the dialing (step 65), the receiving transmitter transmits the ring signal by the dialing of the transmitting transmitter (step 66). After the receiving transmitter counts the ring signal, the ring detector 38 detects the ring signal and inputs the detected signal to the microcontroller 40. When the microcontroller 40 receives the ring signal, the set ring count value stored in the register of the modulator 26 is read to compare the received ring signal with the set ring count value. When the received ring signal is equal to the set ring count value, the microcontroller 40 controls the mode switching unit 40 so that the trunk line L is connected to the modulation and demodulation unit 26 (step 67). At this time, the microcontroller 40 controls the voice processing unit 33 to read the missed voice information stored in the voice storage unit 34 through the modulation / demodulation unit 26 (step 68). That is, when the voice processing unit 33 reads the missed voice information stored in the voice storage unit 34, the modulation / demodulation unit 26 transmits the missed voice information through the trunk line L. When the transmitting device which has sent the ring signal receives the missed voice information transmitted through the trunk line L, the system operates the voice information and the image information in the auto answer mode as described with reference to FIG. Can be recorded and stored on the transfer unit.

Here, the difference from FIG. 3 (a) is that the voice information and the image information to be transmitted and received may be output after being stored in the memory unit 27 and the voice storage unit 34 of the transmission apparatus in the automatic response mode. will be. That is, the voice information stored in the voice storage unit 34 may be output through the speaker 11 by a user of the transmission device user, and the image information preferably stored in the RAM 29 of the memory unit 27 may be monitored ( 6) can be displayed or printed by an external output device such as a printer through the interface terminal 8 and the interface processor 31.

As described above, the image information transmitted / received by the transmission device according to the present invention is transmitted as created on the tablet 21 of the monitor 6 or by an input device (for example, a scanner) connected to the interface processor 31. It may be transmitted as read and displayed on the liquid crystal display element 22 of the receiving side monitor 6, or may be output to the outside through the interface processor 31. Alternatively, the received image information may be temporarily stored in the RAM 28 of the memory unit 27 and used later.

As described above, the voice and image transmission apparatus according to the present invention can transmit and receive voice information and image information without interruption of an online situation of a communication line, and the receiving side transmission apparatus remotely transmits the voice and image transmission / reception mode from the transmitting side transmission apparatus. Can be controlled to improve convenience.

In addition, the voice and image transmission apparatus according to the present invention can be used later after temporarily storing the received voice and image information can be achieved to maximize the utilization of the information.

Furthermore, the voice and image transmission device according to the present invention can provide an advantage of visually exchanging information by using a display device such as a monitor, and can receive and transmit information from an external input device and transmit and receive information.
