Abstract

end. TECHNICAL FIELD OF THE INVENTION

This is a technology that enables automatic reception of a document in a hook-off state after a ring incoming in the facsimile apparatus.

I. Technical Problems to be Solved by the Invention

If a person who has no function in the facsimile rings the ringing tone, then when the telephone is received by the handset, the CNG tone signal of silence or fax is heard, and the call is interrupted so that the important document can not be received.

All. The point of the solution of the invention

In the facsimile apparatus, when a tone signal or silence is detected while the hook switch is hooked off by the user during ring reception, the facsimile apparatus automatically switches to the FAX mode and receives the document transmitted through the telephone line.

la. Important Uses of the Invention

To a facsimile apparatus.

Description

How to Receive Documents in Hands-Off Mode of the Facsimile Handset

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of receiving a document in a hook-off state of a facsimile machine, and more particularly, to a method of automatically receiving a document in a hook-

A typical method of receiving a document in a facsimile includes automatic reception, manual reception, automatic response reception, etc. In the case of automatic reception, when a ring reception is detected, the number of rings is automatically detected after being detected, And receives the call by pressing the start key while listening to the handset. In the case of automatic answer reception, after a ring tone is emitted for a predetermined number of times, an outgoing message (OGM) for automatic response is sent out, and then a silent mode or a CNG tone is detected. In addition, there is a method to switch to the fax reception mode when the remote start key is pressed after confirming the fax signal from the external telephone. In the case of the telephone / fax mode, a certain number of rings are sounded and the fax is not hooked off If not, switch to fax receive mode. Also, when a fax and a telephone are used together on the same telephone line, there is a method in which a specific key is pressed on the telephone to detect the signal from the fax and switch to the reception mode.

However, in such a conventional facsimile, when a ringing tone is heard by a person who has no knowledge of the fax function, the telephone is received by the handset so that there is no problem in case of a simple telephone call, but the telephone is interrupted when a silent or faxed CNG tone signal is heard There was a problem that important documents could not be received.

It is therefore an object of the present invention to provide a method of receiving a document in a handset hook-off state in which a facsimile can automatically receive a document when the handset is hooked-off during ring reception.

According to an aspect of the present invention, there is provided a mobile communication terminal, comprising: a ring tone receiving unit for receiving a document transmitted through a telephone line by automatically switching to a fax mode when a tone signal or silence is detected in a state where the hook switch is hooked- .

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

1 is a diagram of a facsimile block according to an embodiment of the present invention,

The CPU 10 controls the overall operation of the facsimile, and controls to switch to the reception mode when hook-off occurs during ring reception. The mode selecting unit 16 selects a telephone or a facsimile under the control of the CPU 10, and is connected to the telephone in the normal state. The hook switch 18 is connected to the telephone selecting terminal of the mode selecting unit 16 and hooks on / off as the handset is placed or heard. The hook-off detecting unit 12 detects the hook-on / off state according to the state of the hook switch 18 and provides it to the CPU 10. The bridge rectifier 14 is connected to a telephone selection terminal of the mode selection unit 16 and full-wave rectifies and outputs a voice signal and a tone signal input from the telephone line. The SPEECH IC 22 processes the full-wave rectified voice signal from the bridge rectifier 14 and outputs it to the speaker 24. The trans 20 matches the impedance between the telephone line and the facsimile when the mode selector 16 is selected as the fax mode. The transmission / reception selection switch 26 switches to select the transmission or reception line of the facsimile under the control of the CPU 10. The resistor R1 and the capacitor C1 are connected to the facsimile select terminal of the mode selector 16 to keep the signal to be fed to the fax line in the hook-off state. Under the control of the CPU 10, the modem 28 analog-modulates the transmission data and demodulates and outputs the analog reception data.

2 is a control flowchart for automatically receiving a document in a hook-off state according to an embodiment of the present invention.

The operation of the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

First, after the ring incoming in step 101, the CPU 10 proceeds to step 102 and searches whether the mode is set to the automatic reception mode. At this time, if the automatic reception mode is not set, a function corresponding to the corresponding mode set in step 103 is performed. However, if the automatic mode is set, the process proceeds to step 104, where the user is hooked up to the hook switch 18 to search for a hook-off state from the hook-off detecting unit 12. [ If the hook-off state is not detected, the process proceeds to step 108 and the document is automatically received. However, if it is determined in step 104 that there is a hook-hook state, the process proceeds to step 105 to find whether a CNG tone or silence is detected, and if no tone or silence is detected, However, if the CNG tone or silence is detected, In step 107, the CPU 10 controls the mode selection unit 16 to switch to the FAX mode. And controls the transmission / reception selection switch 26 to be connected to the reception port of the modem 28. Then, in step 108, the CPU 10 receives the document via the modem 28 from the telephone line.

As described above, according to the present invention, when a handset is hooked-off by a user during ring reception in a facsimile, a document can be automatically received, and a document is received when a user who does not know the function of the facsimile disconnects the telephone Thereby improving the function of the system.
