Abstract

PURPOSE:To prevent wrong dialing because an entered incoming call is confirmed on a display section and correction is implemented simply and to allow redialing to be executed with a simple key operation regardless of hook-on. CONSTITUTION:An incoming call number is inputted from a pushbutton dial section 2 and displayed on an input number display section 1. A mis-input part of the number is designated and corrected by a correction cursor moving key 3. When the number input is finished, an execution key 4 is depressed and stored in a RAM 7. The incoming call number in the RAM 7 is converted into a selection signal by a selection signal conversion section 8 by the control of a central controller 5 and sent to a subscriber line 12 via an input output control section 9. When a handset is hooked on once and then hooked off again, the incoming number in the RAM 7 is displayed on an input number display section 1. When the enter key 4 is depressed again and the handset is not once hooked on, the handset is hooked on automatically and then hooked off and a selection signal corresponding to the incoming number of the RAM 7 is sent.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to communication terminals, and more particularly to communication terminals such as telephones and fax machines connected to a telephone line network for inputting the called number of the called party.

0002

[Prior Art] Conventionally, when dialing the incoming number of the called party using a communication terminal such as a telephone or fax, if the wrong number was dialed, the user would go on-hook and dial the number again from the beginning. .

0003

[Problem to be Solved by the Invention] This conventional communication terminal is said to be inefficient because if you dial the wrong number of the called party, you have to go on-hook once, go off-hook again, and dial the number from the beginning. There are drawbacks. In particular, when re-dialing with a key telephone or the like, different key operations must be performed for each model specified for re-transmission, which also has the drawback of not being universally applicable.

0004

[Means for Solving the Problems] The communication terminal of the present invention is a communication terminal that is connected to a telephone line network, inputs a called number of a called party, and sends out a corresponding selection signal. a number input means for inputting a number, a number display means for displaying the inputted called number, a number correction means for correcting an incorrect input part of the displayed called number, and a number storage means for storing the called number; selection signal converting means for converting the called number stored in the number storage means into a selection signal digit by digit; and the number storage means for converting the called number displayed on the number display means based on an instruction from an execution key. and a number transmission control means for converting the selection signal into the selection signal and transmitting it to the telephone network via the selection signal conversion means.

In the above configuration, when the number transmission control means detects an off-hook state after on-hook after sending the selection signal based on the instruction of the execution key, the number transmission control means transmits the called number stored in the number storage means. When the number is displayed on the number display means and an instruction is received from the execution key again, if the off-hook state after the on-hook is not detected, the off-hook state is first set to the on-hook state and then the off-hook state is detected again, and the off-hook state after the on-hook is detected. If the incoming call number is stored in the number storage means, the incoming call number stored in the number storage means is converted into the selection signal through the selection signal conversion means and sent to the telephone line network. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 shows a series of operations when a subscriber on the calling side inputs a dial number of the other party and then re-dials because the other party is busy. FIG.

In FIG. 1, 1 is an input number display section that displays the input number, 2 is a push-button dial section for inputting each digit of the number, and 3 is a number displayed on the input number display section 1. 4 is an execution key that instructs to send a number, 5 is a central control unit that controls the whole, 6 is a ROM that stores a control microprogram, and 7 is an input number display section. 1 is a RAM that stores number information; 8 is a selection signal converter that converts the number information in RAM 7 into a selection signal; 9 is an input/output controller that controls input/output with the subscriber line; 10 is a handset; 11 is a an input number display section 1, a push-button dial section 2, an input key control section for controlling a correction cursor movement key 3 and an execution key 4;
2 is a subscriber line.

Next, the functions and operations from when the subscriber on the calling side dials the called number of the device on the called side until redialing will be explained.

When the calling subscriber goes off-hook (step S1), the number stored before going off-hook is displayed on the input number display section 1 (step S2). When inputting the incoming call number of a new destination device different from this number (NO in step S3), the input key control unit 11 causes the number input from the push-button dial unit 2 to be displayed in the input number display unit 1. is displayed (steps S4, S5), and when all dial numbers have been input (steps S6, S8), pressing the execution key 4 saves the dial information to the RAM.
7 (step S9). At this time, if you input the dial number incorrectly (YES in step S6),
By using the correction cursor movement key 3 (step S7), the input key control section 11 operates, and it is possible to correct a number that has been input in error. Next, the information stored in the RAM 7 is converted into a selection signal by a selection signal converter 8 under the control of a microprogram built in the ROM 6, and transmitted to the subscriber line 12 via an input/output controller 9. (Step S10). At this time, the input number display section 1 constantly displays the input number.

Next, when the subscriber on the calling side uses the handset 10 to redial when he/she recognizes that the other party's station is busy, the subscriber on the calling side displays the input number display section 1.
Look at the number displayed, confirm that there is no mistake, and press ENTER key 4 again. By pressing the execution key 4, the following functions are activated. After the microprogram built in the ROM 6 finishes transmitting the number stored in the RAM 7 to the subscriber line, it monitors whether the calling terminal is on-hook or off-hook.

[0012] After the calling subscriber goes on-hook once (YES in step S11), it goes off-hook (step S1).
~S3), if execution key 4 is pressed (step S9)
, the information stored in the RAM 7, that is, the number displayed on the input number display section 1, is transmitted again to the subscriber line 12 (step S10).

[0013] Furthermore, if the subscriber on the calling side presses the execution key 4 to redial (step S9) without going on-hook once (NO in step S11), the microprogram built in the ROM 6 It controls the output control unit 9 and sets the on-hook state. Thereafter, the off-hook state is set, and when a dial tone is detected, the number stored in the RAM 7, that is, the number transmitted immediately before, is displayed again on the input number display section 1, and the number is further transmitted to the subscriber line 12. (Step S10). As described above, the redial operation is executed even when the calling subscriber does not go on-hook.

[0014]

[Effects of the Invention] As explained above, the present invention is useful for preventing incorrect dialing because the called number of the called party can be confirmed by the number display means. You only need to correct the
Redialing is also possible with a simple operation of the execution key regardless of the presence or absence of on-hook, making dialing operations efficient and versatile.
