Abstract

PURPOSE:To confirm a time display clearly without providing any speech time display part separately by displaying a speech time by using the numbers of ten-key buttons in common by utilizing a LED lamp provided below the ten-key buttons. CONSTITUTION:The ten-key buttons 15 are made of translucent silicone rubber, etc., and one or plural LED lamps 19 are provided for each number below the buttons and connected to a LED turning-on circuit 21 from its terminal 20. When a signal is inputted from the opposite side through a trunk line 22 and a handset is put off the hook, the signal is inputted to a talking circuit 24 through a hook switch 23. This talk is confirmed by a speech monitoring circuit 11 continuously, its speech time is computed by a timer circuit, and LED lamps 19 on a ten-key substrate 18 light through the LED turning-on circuit 21. In this case, a 2nd button 16 lights for the speech time of, for example, two minutes and a 5th button in the ten-key buttons 15 lights for the speech time of five minutes.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a call time display device for a telephone.

2. Description of the Related Art A conventional telephone talk time display device will be described with reference to FIG. 3 and FIG. 4 on page 2. As shown in FIG. 3, the telephone consists of a main body 1 and a handset 3 connected by a curl cord 2. The top surface of the main body 1 has a numeric keypad section 4.
and a call time display section 5 (LCD display section) that displays how many minutes of call time have passed, and the call time display section 5 displays the call time at the time of reception and the time of transmission. It has become.

This will be explained using the circuit shown in FIG. For example, if a reception is received on the input/output side 6 of the central office line, a reception tone is emitted by the ringer circuit 9, and at the same time, the reception tone is received by the telephone communication circuit via the hook switch 7, and the handset 3 is picked up and the telephone call is made. start. When a call is started, a signal is sent to the call time display section 6 via the call circuit 8, and the call time is displayed to notify the caller of the call time.

Problems to be Solved by the Invention This conventional configuration works well when the place where the main body 1 of the telephone is placed is bright, but when talking without the light on or when the light intensity of the light is low.・When the main unit is placed in a dark place, the time displayed by the call time display section 5 becomes difficult to see, and depending on the viewing angle, it is almost invisible, which limits viewing angles. was there.

The present invention is intended to solve these problems, and aims to make it possible to clearly confirm the time display even in a dark place.

Means for solving the problem In order to solve this problem, the present invention provides a numeric keypad button for dialing provided on the main body, and a numeric keypad button provided below the numeric keypad button and corresponding to the numbers on the numeric keypad button. It is equipped with a numeric keypad board made of translucent silicone rubber, etc., and an LED lamp provided above the numeric keypad board, and transmits and receives data from the input/output side of the central office line to the communication circuit via the 7-way wire, as well as a call monitoring circuit. Input/output to
The information is transmitted from the call monitoring circuit and the timer circuit to the numeric keypad board via the LED lighting circuit.

With this configuration, when receiving from the central office line, the LED lamp provided on the upper side of the numeric keypad board corresponding to the numeric keypad button lights up through the call monitoring circuit, timer circuit, and LED lighting circuit, and this lighting indicates the duration of the call. It is also displayed as the number on the numeric keypad button. On the other hand, when a message is sent to the other party using the numeric keypad button, the transmission is sent to the other party from the dial circuit and the call circuit, and the LED lamp is lit by the call monitoring circuit, timer circuit, and LED lighting circuit, and this lighting indicates the call time by pressing the numeric keypad button. 1. An embodiment of the present invention in which the call time is known by displaying the same number as the numeral 1.An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 shows the numeric keypad section provided on the top surface of the main body of the telephone, 15 is a numeric keypad button, and in this figure, the number 2 button 16 of the numeric keypad buttons 16 is shown.
It shows. A conductive rubber contact 17 is provided below the numeric keypad button 15, and is energized by pressing the numeric keypad board 18 on which the carbon pattern 14 is formed from above. The numeric keypad button 15 is made of translucent silicone rubber, etc., and one or more LED lamps 19 are provided for each number on the lower side, and the terminal 20 is connected to an LED lighting circuit 21 (Fig. 2). are doing.

In FIG. 2, the hook switch 23 is connected to the central office line 22,
It is connected to a ringer circuit 26 that emits a reception sound when receiving,
A telephone call circuit 24, a numeric keypad button 16 and a numeric keypad board 18 for transmitting the other party's number when making a call are connected to the hook switch 23 via the dial circuit 13.

On the other hand, in parallel with the dial circuit 13, a call monitoring circuit 11 that constantly checks the call status, a timer circuit 12 that calculates the call time, and an LED lamp 19 provided on the numeric keypad board 18 are output. LEp lighting circuit 2 that lights up the numbers on the numeric keypad 15 that indicate
Connected to 1.

In the above configuration, for example, when an input is received from the other party via the central office line 22, a ring tone is generated by the ringer circuit 25, and when the hand cent is picked up, the input is input to the telephone call circuit 24 via the A-hook switch 23. .

This call is constantly checked by a call monitoring circuit 11, the call time is calculated by a timer circuit, and an LED lamp 19 of a ten-key board 18 is turned on via an LED lighting circuit 21.

This lighting is such that if the call time is 2 minutes, the 2nd button 16 will be lit, and if the call time is 6 minutes, the 5th button of the numeric keypad 16 (not shown) will be lit. The number on the numeric keypad 15 and the call time are also displayed.

Next, when making a call to the other party, operate the numeric keypad button 15 to send a message via the numeric keypad board 18 and dial circuit 13 to make a call, but even during this call, the call is monitored according to the reception time. After passing through the circuit 11, the timer circuit 12 performs calculations, and the LED lamp 19 on the numeric keypad board 18 is lit via the LED lighting circuit 21. In other words, if the call time is 7 minutes, press 7 on the numeric keypad 15.
A number button (not shown) is illuminated to inform the caller that the call time is 7 minutes.

7 〆＼ In other words, the numbers on the numeric keypad are also used to display the call time.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention includes a call monitoring circuit, a timer circuit for calculating the call time, and an LED lighting circuit for transmitting the call time to the LED lamp side of the numeric keypad board in parallel with the dial circuit. This LED lighting circuit outputs the output to the LED lamp provided below the numeric keypad button made of translucent silicone rubber to display the call time, so the numbers from 0 to 9 on the numeric keypad button can be displayed. It can be displayed for both purposes, making it easy to inform the caller of the call time, and in fact, the darker the place, the easier it is to see. In addition, since the numeric keypad can also be used as a numeric keypad, there is no need to provide a separate call time display section like in the past, and the call time can be displayed even on a miniaturized phone without a flat surface. It is something.
