Abstract

PURPOSE:To improve the operability by depressing a correction button for a number depressed finally by mistake if a wrong number is entried on the way in case of dialing and correcting a correct number to correct the wrong number. CONSTITUTION:In case of dialing, if the 8th digit number is depressed by mistake, the correction button is depressed without depressing the 9th digit number. Thus, correction button depression information 103 from a key matrix section 10 is detected by a control section 20 to generate correction button information 202 and the 8th digit number in a button information storage section 30 is cleared. When the correct 8th digit number is depressed again, the number is set. Then the rest numbers are depressed successively and the end button is depressed finally, then all numbers are sent from a control section 2 and dialing is finished. Thus, the button information storage section 30 stores only one digit of button information and it is cleared by the information 202.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone connected to a main unit, and more particularly to a button telephone capable of dial correction.

[Conventional technology]

Conventionally, key telephones use central office lines (or CO/PBX lines).
- One or more connected to the housed main device.

The main device connects and switches calls between the central office line and the key telephone based on data sent and received between the key telephone and the key telephone. When making a call, the caller selects the central office line using the call button on the key telephone, and then presses the dial button switch.

At this time, the key telephone instantly sends dial button information to the main device in the order in which the one dial button switch is pressed.

[Problem that the invention seeks to solve]

With the above-mentioned conventional key telephone, if you dial the wrong number before you have pressed all the dialing buttons for all the digits of the other party's number, you have to re-grab all the counter lines and press dial 1 again from the beginning. There were some annoying drawbacks.

[Means to solve all problems]

This system solves the above-mentioned drawbacks. When dialing, if you dial the wrong number before pressing all the digit buttons of the other party's number, To provide a button telephone that allows correction by dialing the correct number after pressing a correction button.

That is, according to the present invention, in a button telephone connected to the central office line via the key telephone main device "ft" which is connected to the central office line, the key matrix section including the button operation section t-t and the key matrix section, key scanning and button press detection are provided. a button information storage section that stores all one-digit button information for each one-digit dial operation in the key matrix section;
means for erasing and correcting the stored contents of that digit by operating a predetermined button when the number of the latest digit dialed is incorrect; A key telephone set including a data driver section and a data driver section for sending data to a telephone main unit is obtained.

[Example] Next, an example of the present invention will be described with reference to all the drawings.

The drawing is a block diagram of one embodiment of the present invention.

In the figure, a key telephone 1 is connected to a main device 2 via a data line 100 and a voice line 200. The main device 2 accommodates all stations @L*-Lt...L, selectively connects and switches between the station lines and the voice line 200 of the key telephone 1, and also connects the data line 100. Data is sent and received through the LAN, and various controls are performed based on the received data. The voice line 200 is connected to the telephone call circuit 50 of the key telephone 10.

In addition to the telephone call circuit 50, the button telephone 1 includes a key matrix section 10 including a button operation section, a key scanning section through the entire key matrix section 10, a button press information detecting means, and a control section having a micro combiator that controls data transmission and reception. 20, a button information storage section 30 that temporarily stores minus-digit dial button information, and a data driver section 4 that sends the button information sent from the control section 2.9 to the data bus 8 to the main device 3.

When the dial button in the key matrix section 1 is pressed in order to grab and dial a station il in the button telephone 5 having such a configuration, the button press information 101 is transmitted to the control section il.
Sent to O. The button press information 101 is stored in the button information storage section 30 as button information representing a dial number. One digit worth of button information 201 is stored in the button information storage section 30, and when the next digit number of the stored number is pressed, the button information representing the stored number is transferred from the control section 20 having a micro combiator. After being read out, the number of the next digit pressed by sending n1 is stored next. When all the dials are dialed, the button information representing the last digit number is still stored in the button information storage section 30, so when the end button of the key matrix section 10 is pressed, the button information is stored by detecting the press information 10. Accumulation section 30
The number sound of the last digit is read out and sent to the data bus 8. Data bus 8 button information is data driver 40t-
The data is sent to the main device 100 via the main device 100.

Now, for example, if you try to dial a 10-digit number and press the 8th digit incorrectly, press the correction button (not shown) without pressing the 9th digit. Information] Oa is detected by the control unit 20, correction button information 20. All occur, button information storage section 30F3-8
Clear all digit numbers. Next, press the correct 8th digit number again, and the 09th digit will be set to the 8th digit number.
Complete the 10th digit number and finally press the end button.
The 10th digit number is sent out from the microcombinator section 2, and dialing of the 10-digit whole tone number is completed.

Therefore, the button information storage section 30 stores only one digit of button information and can clear the one digit of button information 7' (f-clear) using the correction button information 202.

As mentioned above, if you press the wrong number while dialing, you can clear the last number you pressed by pressing the correction button, and then press the higher number again to continue from the next number. Can be dialed.

〔Effect of the invention〕

As explained above, in the present invention, when dialing, if you press the wrong number before pressing all the buttons for all the digits, press the correction button for the last number pressed and then dial the correct number. Can be corrected by pressing,
No need to dial back from the beginning.
