Abstract

PURPOSE:To emphasize the consciousness of the call charge for subscribers and to contribute to the save of the call charge, by adding a display device for call duration to a telephone set to display the call duration in the form of a graph and displaying the present call duration in a graph to a prescribed call duration. CONSTITUTION:The 1st controller 5 adds the call duration of a call duration arithmetic circuit 4 to the call duration of the corresponding area of a memory 3 for spent call duration and stores the total call duration in the memory 3. At the same time, the graphed data on the total call duration is sent to the 2nd controtler 12 through data communication interface circuits 6 and 7 in response to the rate against the contents of a setting memory 14 for available call duration. Then the controller 12 graphs the relieved data and delivers it to a display device 15. In such a way, the actual call duration is displayed in a graph in comparison with the available call duration set previously. Thus it is possible to emphasize the consciousness of the call charge for subscribers. Then the call charge can be greatly saved as a whole.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention aims to make the user aware of how much of the set call time is currently used to manage and save the call time. This invention relates to a button telephone device.

Conventional technology FIG. 2 shows a conventional key telephone device.

The configuration of this conventional example will be explained below with reference to FIG. 2.

In FIG. 2, 1 is a dilJ relay contact for forming an outside line communication path and sending out dial pulses, 2 is an analog switch for forming a communication path with a telephone, and 3
Memo 1 to remember the call time used for each phone
1-14 is an arithmetic circuit that calculates call time; 5 is a first control device consisting of a microprocessor that controls the entire button telephone device; 6 is an interface circuit for data communication with the telephone; 7 is a first control device; 1, an interface circuit for data communication with the control device 5; 8, a hybrid circuit; 9, a handset; 10, a display for displaying call time; and 11, an outside line key or dial key for making a call. 12 is a second control device consisting of a microprocessor or the like that controls the telephone.

Next, the operation of the above conventional example will be explained. In FIG. 2, if the user picks up the handset 9 and operates the central office line key or dial key 11, the user picks up the handset 9 and operates the central line key or dial key 11.
2 and transmitted to the first control device 5 via the data communication interface circuits 7, 6. The first control device 5 operates the DILL relay based on the above information, operates its contacts, and sends the dial to the outside line.

Then, at the same time as forming a communication path with an outside line, the analog switch 2 is turned on to form a communication path with a telephone. Then, an arithmetic circuit 4 calculates the duration of one call after a certain period of time (after the other party's response if there is a response monitoring circuit)
starts working. The first control device 5 then monitors the contents of the call time calculation circuit 4 and transmits the data to the second control device 12 through the data communication interface circuits 6 and 7.

The second control device 12 displays the call time on the call time display 10 moment by moment. When the call ends and the handset is hung up, the first and second control devices 12 send a signal to the first control device 5 through the data communication interface circuits 7 and 6 that the handset has been hung up. Then, the first control device 5 determines that the call has ended, and changes the contents of the call time calculation circuit 4 to:
The cumulative total is stored in the corresponding area of the used call time memory 3.

Problems to be Solved by the Invention However, in the above conventional example, although the call time is displayed, there is no awareness of how much time can be used within a certain period, so the effect of saving on call charges is not achieved. few. Also, when used within Japan, the nationwide rate system is programmed and call charges can be displayed, but it cannot be used for calls to other countries.

The present invention is intended to solve the above-mentioned problems of the conventional example, and allows the user to manage and save call time by displaying the current usage time in a graph against the call time setting for a certain period of time. The purpose is to create awareness.

Means for Solving the Problems In order to achieve the above object, the present invention provides a telephone with a call time display that can display the call time in graph form, and displays the current usage time for a preset predetermined call time. It is configured to display time as a graph.

Therefore, according to the present invention, it is possible to clearly judge at a glance how many calls have been made for a certain preset call time, and awareness of call charges is significantly strengthened, and call charges can be reduced over a wide range. It has the effect of helping to save money.

EXAMPLE Below, the configuration of an example of the present invention will be explained with reference to the drawings. In FIG. 1, numerals 1 to 12 indicate the same parts as the conventional one shown in FIG.

13 is a switch for setting the usable call time and a display for confirmation; 14 is a memory for storing the usable call time set above; and 15 is a graph showing the call time. This is a call time indicator to display.

Next, the operation of the above embodiment will be explained. In FIG. 1, when the user picks up the handset 9 and operates the office line key or dial key 11, the second control device 12 detects this. The information is then transmitted to the first control device 5 via the data communication interface circuits 7 and 6.

The first control device 5 receives the above information, controls the DILL relay, operates its contacts, and sends the dial to the outside line. Thereafter, a communication path with an outside line is formed, and the analog switch 2 is turned on to form a communication path with a telephone set.

At the end of the call, the first control device 5 adds the call time of the arithmetic circuit 4 to the call time in the corresponding area of the used call time memory 3, and the cumulative total is added to the used call time memory 3.
to be memorized. At that time, the graphed cumulative call time data is sent to the second control device 12 through the data communication interface circuit 6.7 based on the ratio with the contents of the available call time setting memory 14. The second control device 12 that has received the data graphs it and outputs it to the display 15.

Note that in the above implementation sequence, instead of the total call time, one call time may be set in the usable call time setting memory 14 and displayed on the call time display 15 graphed for each call. It goes without saying.

Effects of the Invention As is clear from the above-mentioned embodiment, the present invention allows the user to set the available call time in advance and display the actual call time in a graph for comparison. This has the advantage that it is possible to emphasize time consciousness more strongly, and that a large saving effect on call charges can be expected as a whole.
