Abstract

PURPOSE:To optionally read out plural previously dialed telephone numbers and to reoriginate them by storing the plural previously dialed telephone numbers in a reoriginating memory and reading out and displaying these numbers by a dial search button to send them to a telephone line. CONSTITUTION:A redial searching button 4 is a button for successively reading out plural telephone numbers previously dialed and stored in the reoriginating memory 8 and displaying them in a display device 3. When a CPU 10 receives a redial searching signal, a reorigination control part 7 reads out telephone numbers from the memory 8 and displays data read out through the CPU 10 on the display device 3 through a display device driving circuit 11. If a reoriginating signal button 5 is depressed when a specified telephone number is displayed on the display device 3, the telephone number is read out from the memory 8 and the displayed telephone number is sent from a dial sending part 9.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention includes a telephone equipped with a display, a main device equipped with a repeat memory capable of storing a plurality of previously dialed telephone numbers, and a telephone number that is previously dialed. This invention relates to a button telephone device that allows one of nine telephone numbers to be selected and re-dialed.

BACKGROUND OF THE INVENTION Traditionally, this type of key telephone device incorporates the ability to redial a previously dialed telephone number. However, this only allows re-dialing of the telephone number dialed immediately before, and only one telephone number can be stored in the re-dialing memory section.

(Problem to be Solved by the Invention) Therefore, the conventional key telephone device can re-call the eiii phone number that was dialed just before, but there is no way to remember the previous number, so all digits of the same phone number are input. The drawback is that you have to do it.

SUMMARY OF THE INVENTION An object of the present invention is to provide a button telephone device that can make a re-dialing even if the telephone number has been dialed immediately before.

(Means for Solving All Problems) In order to achieve the above object, the button telephone device according to the present invention includes a telephone interface that accommodates a plurality of button telephones, a call path switch that connects the button telephones, and the call path switch and the In a button telephone device consisting of a main device consisting of a main control unit that controls an interface, and a key telephone equipped with a visual display and an audible display, the main device contains a plurality of previously dialed telephones. A re-call memory capable of storing all numbers, a dial search button, a re-call control unit that sequentially reads telephone numbers from the repeat memory by operating the dial search button and displays them on the display, and a re-call control unit that causes the repeat call to be displayed on the display unit by operating the re-call button. The apparatus is constructed by providing a control means for controlling sending of the displayed telephone number to the line.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 shows an embodiment of a telephone according to the present invention.

FIG. 3 is a front view of the exterior.

FIG. 2 is a block diagram illustrating an embodiment of a telephone circuit.

In FIG. 1, a handset 11, a dial button 2, a display 3 capable of displaying up to 10 digits, a redial search button 4, and a redial button 5 are provided on the front of the telephone.

The display 3 displays a telephone number read out from a replay memory 8, which will be described later, in addition to a telephone number input by operating a dial button.

The re-dial search button 4 is a button operated to read out in full order a plurality of previously dialed telephone numbers stored in the re-repeat memory 8 and display them on the display 3.

The re-call button 5 is a button that is read out by the re-dial search button 4 and is operated to call the telephone number displayed on the display 3 again.

In FIG. 2, portions with the same reference numerals as those used in FIG. 1 are portions that perform the same functions.

The key input information for the redial search button 4 and redial button 5 is Cr throughout the key input circuit 6 in the main gICT.
t, l 10. The CPUtO receives the redial search signal and requests control from the redial control unit 7. The re-call control section 7 reads out the telephone number from the re-transmission memory 8 and causes the display 3 to display the data read out through the CP'U 10t through the indicator drive circuit 11.

Next, the operation will be explained.

Each time the telephone user goes off-hook and presses the re-dial search button 4t, the re-call control section 7 causes the display 3 to sequentially display the telephone numbers stored in the re-call memory 8. By operating the two-way re-dial search button, the reading direction can be changed, and a plurality of telephone numbers 't' in the re-dial memory can be freely displayed and selected.

When the specified telephone number is displayed on the display 3, if the re-call button 5t is pressed, the CPTJ 10 receives this re-call signal, reads it out from the repeat memory 8, and dials the displayed telephone number. It is sent from section 9. The telephone number dialed using the re-call button 5 or the dial button 2 is stored in the re-call memory 8, and the oldest stored telephone number is deleted.

(Effects of the Invention) As explained above, the present invention stores all previously dialed telephone numbers in a re-issue memory, reads them out using the dial search button, and displays them. Since the telephone numbers are configured so as to be sent to the telephone number, it is possible to freely read a plurality of previously dialed telephone numbers from the memory for re-calling and re-dialing them.
