The present invention relates to a calling station display device of an automatic telephone answering device, and more particularly, to be suitable for identifying a calling station.

Conventionally, only the message can be delivered and recorded using the telephone answering machine, so the user has to check the recorded incoming message by ear.

The present invention has been made to solve this problem, and an object of the present invention is to provide a calling station display device of an automatic telephone answering device, which allows a caller to find out a calling station through an LCD display device.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

1 is a block diagram according to the present invention, a CPU 3 for controlling the system as a whole is connected to a line control and an interface circuit 1 which detects an input signal and switches it in case of a telephone / fax combination. .

The CPU 3 is connected with a memory 4 capable of storing a system operation program and various input data such as a telephone number, a name and an address.

In addition, the line control and interface circuit 1 and the CPU 3 are connected with a DTMF decoder 2 for converting input data under the control of the CPU 3, and is provided with an origination message recording apparatus for recording an origination message ( 7) and an incoming message recording device 8 for recording an incoming message.

The CPU 3, the outgoing message recording device 7 and the incoming message recording device 8 are connected with amplifiers 5 and 6 for amplifying the input and output messages, and the amplifier 5 has a microphone (MIC). ) Is connected, and a speaker SK is connected to the amplifier 6.

On the other hand, the CPU 3 is connected to the LCD display device 9 for displaying a telephone number, etc., each of which is configured to receive the driving power by the power supply 10. And TL, which is not described, is a telephone line.

In the present invention configured as described above, first, the user records the message in the outgoing message recording apparatus 7 through the microphone (MIC) before going out. Then, when a call is received from the outside while the user is out, the line control and interface circuit 1 detects a signal, connects the telephone line, and informs the user of the telephone number of the calling station previously recorded. A message 2 is sent to the calling station requesting the message to be communicated.

When the calling party hears this message, it enters his / her phone number through the keypad of the phone and presses the 패드 key on the keypad to indicate that the message has been delivered.The DIMF decoder (2) returns the calling party's telephone number. The CPU 3 decodes and outputs it to the CPU 3, and the CPU 3 displays the telephone number of the calling station on the LCD display 9, and finds whether the telephone number of the calling station is recorded in the memory 4. If a name or company name corresponding to the telephone number of the calling party is recorded in the system, the name is recorded under the telephone number displayed on the LCD display unit 9, and if the incoming telephone number is not recorded in the memory 4, the calling party side Only the telephone number of is displayed on the LCD display 9.

Thereafter, the incoming call is recorded on the outgoing message recording device 8 and displayed on the LCD display device 9 as described above.

When the user returns and presses the confirmation key, the telephone number and name of the calling party are sequentially displayed on the LCD display 9 in the order of incoming calls, and the user can select and confirm the incoming message recorded on the incoming message recording device 8. It becomes possible.

This will be described in more detail together with the flowchart of FIG. 2 as follows.

First, FIG. 2A is a flow chart of an outgoing message transmission operation, in which a user records a message in the outgoing message recording apparatus 7 through a microphone MIC before going out.

Then, when a call is received from the outside while the user is out, the line control and interface circuit 1 detects a signal, connects a line, and informs the user of the caller's telephone number recorded beforehand. And a specific frequency input, time count, line on / off, etc. are checked by the CPU 3, and then a recorded message, for example, a message (message 2) requesting a message to be transmitted is sent. .

2B or the incoming message receiving operation flow chart, the CPU 3 causes the line control and interface circuit 1 to switch lines after detecting a ring, and then transmits an input message. When a message is input from the other party, it is checked whether the telephone number is stored in the ROM in the memory 4.

If it is confirmed that the phone number is in the ROM, the telephone number and name are displayed on the LCD display device 9 at the same time, and if not stored in the ROM, only the telephone number is displayed.

Further, the incoming call number is sequentially recorded in the RAM and the incoming message recording device 8 in the memory 4. Then, it detects whether a specific key signal is input, how much time has elapsed, and whether the line is on or off, and completes the operation.

FIG. 2C is an operation flowchart when a user sends an incoming message, and a user who has gone out presses a specific key to return to know the input data.

Then, the CPU 3 determines whether the input key is a user ID or key to send, and if there is an input message, transmits and displays the telephone number and name on the LCD display device 9, and then displays the entire message. Send it out.

That is, the entire message is stored in the incoming message recording device 8 and later sent out through the speaker SK. It is confirmed whether the telephone number and name are previously entered into the ROM in the memory 4, and sequentially into the RAM. Upon input and upon user request, the CPU 3 sends RAM data to the LCD display device 9 via the DTMF decoder 2 to the display and the speaker SK.

As described above, the present invention enables the user to check the called party for a short time since the user can easily find out the calling station through the LCD display without having to check the incoming call recorder for each incoming call. Has the effect of being.
