Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display device that displays the elapsed usage time of a telephone in order to prevent long phone calls.

[Technical background of the invention]

Conventionally, as this type of display device, one that directly displays eaves passing time is known.

[Problems with background technology]

However, with devices that simply display time, you can tell how much time has elapsed, but if your attention is distracted or you have gotten used to it, you will no longer pay attention to the display of elapsed time. In addition, even if the elapsed time is longer, it only shows the time, and there is no active encouragement from the user, so the user has to subjectively judge whether the call is long or not. The drawback was that it was of little use to those who were addicted to it.

[Purpose of the invention]

The present invention not only attracts the user's attention, but also actively encourages the user to notify whether or not the call is a long call, regardless of the user's subjective opinion.

[Summary of the invention]

The present invention includes a detector for detecting whether the telephone is in use, a display section having lamps emitting light of blue, yellow, and red, and an open operation that detects when the telephone is in use by the detector and starts operation. This configuration is characterized by comprising a control unit that controls lighting of the lamp of the display unit in the order of blue, yellow, and red as the elapsed time becomes longer.

In this way, the color of the lamp changes depending on the elapsed time, so it can catch your attention even if your attention is distracted or you have become accustomed to it.Furthermore, the display is similar to a traffic light, so it is easy to understand. It is easy to use and has a strong appeal to users. In addition, since it objectively displays whether the call is long or short, it is possible to prevent individual differences in the perception of a long M1 talk, and it is possible to reliably prevent long phone calls.

[Embodiments of the invention]

Next, one embodiment of the present invention will be described based on the drawings.

Figure 1 is a front view of the display device (1). In this figure, (2) is the display device body, (3) is a switch as a detector, which is attached to the telephone set (4) and the receiver (5). When it comes off, it turns on and detects that it is in use.

A lamp display section (6) having blue, yellow and red lamps CB) (Yl
), but there is also a time display section (7) at the bottom that displays the usage time.
) is provided.

Figure 2 is a block diagram of the display device (1). In this figure, (8) is a timekeeping section, which is composed of an oscillation circuit, a counter, etc., and when the switch (3) is turned on, the terminal (a)
) is supplied with operating power from a power supply (not shown) connected to the main unit (not shown), and the time is measured.

(9) is a control unit which displays the display on the lamp display unit (6) according to the time signal output from the clock unit (8) and the one attached to the outside of the main body (2) of the device (not shown in Figure 1). This is to control the buzzer 0@ that is displayed. As for this control, for example, the blue lamp (B) of the lamp display section (6) is turned on until the clock section (8) measures 2 minutes and 30 seconds.
The yellow lamp fYl is lit from seconds to 3 minutes, and when the time is over 3 minutes, the red lamp ■ is lit and the buzzer (1
0). And if it is longer than 4 minutes, a buzzer (1
0), and the red lamp α is blinked, and the blinking speed is increased every minute thereafter.

The time display section (7) displays the time based on the time signal output from the time measurement section (8).

Next, the present invention will be explained in detail.

First, the user uses the telephone receiver (5) to use the telephone (4).
), the switch (3) is turned on, and the timer section (8) starts operating at i1, thereby causing the time display section (7) to start displaying the elapsed time. Further, the control section (9) is also operated, and the blue lamp CB of the lamp display section (6) is turned on.

If the user continues to use the handset even after 2 minutes and 30 seconds have passed since the user took off the handset (5), the control unit (9) turns off the blue lamp 03) on the lamp display unit (6). , and the yellow lamp (Y) lights up.

Furthermore, if the user continues to use the handset (5) even after 3 minutes have elapsed, the control unit (9) will control the lamp display unit (6) to turn on the yellow lamp (the leopard L1 is turned off and the red lamp (■) is turned on, and at the same time, the buzzer (10) starts to sound.

Furthermore, if the user continues to use the device after 4 minutes have passed, the red lamp (B) will start blinking under the control of the control unit (9), and the usage time will increase to 5 minutes and then 0 minutes. As the speed increases, the blinking action will become faster.

Also, when the user finishes using the telephone (4) and the receiver (
5), the switch (3) is turned off and the cutting part (8) is turned off.
) is cleared. Then, the display on the time display section (7) disappears and the control section (9) is also cleared. Therefore, in the lamp display section (6), (Y)α out of all the lamps is turned off. If the buzzer θ0) is sounding, it is also stopped.

In the above embodiment, the time display section (7) displays the telephone (
4) is configured to display only the elapsed time from the start of use, but it is also possible to display the time like a normal watch and display the elapsed time only while the telephone (4) is in use. In this case, a new clock section is provided to display the time, and when the switch (3) is off, the output of the clock section for displaying the time is input to the time display section (7), and the switch (3) is turned on. In this case, the control section (9) may control so that the output of the clock section (8) for displaying the elapsed time is input to the time display section (7).

Further, the detection means is not limited to the switch (3) attached to the outside of the telephone (4), but may be configured to be installed inside and perform a similar operation. However, if the display device (1) is provided externally, it has the advantage that the display device (1) can be easily attached to an ordinary telephone.

If you are making an international call and it takes a long time to be able to talk to the other party after you remove the handset (5), you can manually press the switch (3) to turn it off.This will only count the duration of the call. can.

Furthermore, in the embodiment described above, the red lamp aO blinks when the elapsed time becomes longer, but this is to draw the user's attention more. In addition to the lamps )(Y) and (b), the buzzer (10) is also provided for the same purpose, and also to alert the other party to the conversation.

〔Effect of the invention〕

According to the present invention, since the elapsed usage time is displayed by lighting blue, yellow and red lamps similar to traffic lights, it is possible to attract the attention of the user and the meaning of each lamp. It is easy for anyone to understand, and it has a strong appeal to users. Furthermore, since it objectively displays whether the usage time is long or short, it is possible to eliminate individual differences in the perception of long phone calls, and it is possible to reliably prevent long phone calls. This saves costs, especially when making long-distance or international calls.
