BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile (abbreviated as FAX), and more particularly to a FAX incorporating an insulation separation circuit that insulates between a telephone and a main body.

As is well known, FAX is an apparatus that converts original characters such as texts, photographs, diagrams, and the like into small pieces, converts shades of elements into electric signals, and transmits them, and reproduces the original image on the receiving side. There are four types of FAX transmissions that have this function. G1-G3 is analog, G3 is the highest, and G4 can digitally transmit A4 for a few seconds.

In such a fax, a key input means having a numeric key for inputting a telephone number and a function key for operating a fax is attached to a handset, that is, a handset and a main body. And the key input means attached to the main body can perform the FAX function and the telephone function.

However, when the power supplied to the FAX from the outside is interrupted, the key input means attached to the FAX main body becomes impossible to operate, and only the key input means attached to the telephone can operate. Therefore, when the external power supply is interrupted, a user who does not know that the operation of the key input means attached to the FAX main body becomes impossible may operate the key input means attached to the FAX main body, which may cause confusion. There is a problem.

In addition, in the conventional FAX in which a key input means is attached to the telephone and the key input means is attached to the main body, the built-in key input means of the telephone has a problem of not only mechanical difficulty but also an increase in production cost.

On the other hand, a photocoupler is a component for transmitting an electrical signal through an optical signal, and converts the electrical signal into an optical signal by a light emitting diode and transmits it, and the received optical signal is restored to an electrical signal by a photo transistor. It has the function to electrically insulate between input and output.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to include a key input means in only a main body and to insulate the main body and the telephone from each other without having a key input means in the telephone. It is to provide a FAX to reduce the production cost and to be able to perform the telephone function regardless of the external power supply.

In order to achieve the above object, the present invention provides a telephone unit which performs a telephone function, receives an input signal and a message through a telephone line, and transmits a signal and a message to be transmitted to an external telephone or a fax through the telephone line. Network control unit (NCU) to transmit by telephone or FAX, external signal inputted through the network control device by modulating the signal or message to be transmitted to external telephone or fax A FAX comprising a modem for demodulating a message, a central processing unit for controlling the operation of the entire system, and an operation panel unit for providing a key signal for controlling overall operation of the FAX, the FAX being connected to a battery power supply terminal. It further includes an insulation separation unit for transmitting a key signal provided from the panel unit to the telephone unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a hardware configuration diagram of a facsimile for carrying out the present invention, the network control unit (NCU) 100 that receives signals and messages input from the outside via a telephone line and transmits the signals and messages to an external telephone or FAX (100). ), A modem for modulating a signal or a message to be transmitted to an external telephone or a fax and transmitting it to the network control device 100 and demodulating an external signal or message input through the network control device 100 (MODEM: Modulation AND Demodulation). (200), a control panel unit 400 which is composed of numeric keys and function keys to provide key signals for executing various operations of the fax, and a telephone unit connected to the network control device 100 to perform a general telephone function ( 600), the insulation separation unit 500 for transmitting the key operation signal to the telephone unit 600 by the operation panel unit 400, and the system to operate according to the key signal provided from the operation panel unit 400. And when a message is transmitted from the outside through the modem 200, the message is recorded on the recording paper to be discharged to the outside, to record the message received from the external telephone or fax and to read the original to be sent to the outside, receiving from the outside It is composed of a central control unit (Central Control Unit) 300 for storing the messages and various data to be stored and the program for operating the system, and controls the overall operation of the system.

At this time, as can be seen in the following description, since the telephone function can be performed through the operation panel 400 of the FAX main body, no key matrix is configured in the handset of the telephone unit 600. In addition, the display unit 700 is configured to display information generated in FAX.

Figure 2 shows in detail the insulating separator constructed between the telephone section and the operation panel section.

As shown in the figure, the insulation separator 500 is configured of a photo coupler composed of a pair of light emitting diodes and a photo transistor, as described above.

At this time, the key signal input through the operation panel 400 which is configured only in the FAX main body is provided to the telephone unit 600 and the central processing unit 300. If no external power is supplied, the central processing unit 300 operates. I never do that.

Accordingly, the telephone unit 600 may perform the telephone function by the insulation separation unit 500 driven by the battery power source. For example, when the (1) key of the operation panel 400 is pressed, the battery power is supplied to the light emitting diode connected to the (1) key, so that the light emitting diode is driven to emit light and the transistor Q4 And Q5 is operated to recognize that the (1) key is selected in the telephone unit 600.

The same procedure as described above is performed for the remaining keys, and thus the description is omitted.

As described above, the FAX according to the present invention includes not only the FAX function but also the telephone function by a key signal inputted by the key matrix means by having a key matrix means only in the main body and an insulation separation circuit between the phone and the key matrix means. In addition, since the phone does not have to have keymetric means, there is an effect of reducing the production cost.
