Abstract

PURPOSE:To display the talking time close to the actual talking time by providing a counter means starting the count and outputting a display signal with either a detection signal of a ring back tone or an output signal of a timer means. CONSTITUTION:When a hook switch detection means 71 detects the off-hook state, a display switching means 6 selects a dial buffer 2 and when a dial key 1 is operated, a dial data is displayed to a display means 5 via the buffer 2. If the dial key 1 is detached, the timer means 8 starts counting and if a detection means 73 detects a ring back tone sent from a telephone-line, a display switching means 6 selects a counter means 4, the display means 5 displays the data of the counter means 4 and the timer means 8 gives no signal output. In case the ring back tone is not detected, the timer means 8 outputs a signal in 5sec after the dial sending, the switching means 6 selects the counter means 4 and the display means 5 displays the data of the counter means 4.

Description

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

Conventional technology Traditionally, there have been devices that display the dialed number to prevent dialing errors.Furthermore, when the telephone is not in use or when a call is being made, dialing is not necessary, so the current time or call time is displayed. There is a telephone with functions.

A conventional telephone equipped with a display section as described above will be described below with reference to the drawings.

FIG. 2 is a block diagram of the main parts of a conventional telephone equipped with a display section. In FIG. 2, reference numeral 1 denotes a dial key means for operating a dial, and 2 a dial buffer means for storing data manually entered by the dial key means 1. Reference numeral 3 is a clock means for displaying the current time, and reference numeral 4 is a timer means which, when initialized, outputs the elapsed time since the initial setting. 5 is dial buffer means 2
and display means for displaying the data transferred from the clock means 3 and the time measurement means 4; 6 is a display switching means; in order to switch the data to be displayed by the display means 5, the dial buffer means 2, the clock means 3, and the time measurement means 4; Select one of each output. 71 is a hook switch detection means, which detects whether the hook switch is on or off.

The operation of the conventional telephone configured as described above will be explained below.

When the hook switch detecting means 71 detects that the telephone is in the on-footer state (fl), the display switching means O selects the clock means 3 and makes the dial buffer means 2 and the time measuring means 4 non-selected. Selected clock means 3
displays the current time by outputting current time information to the display means 5. When the hook switch detection means 71 detects that the telephone is in an off-book state (the telephone is in use!2!), the display switching means 6 selects the clock means 4 and puts the dial buffer means 2 and the clock means 3 into non-selected states.

At the same time, the clock means 4 is initialized by the off-hook detection signal from the hook switch detection means 71.

Therefore, the display means 5 displays the time from the time of off-hook. When the dial key means 1 is operated in an off-hook state, the dial buffer means 1 notifies the display switching means 6 that the key operation has been performed. The display switching means 6 selects the dial buffer means 2 and makes the clock means 3 and the timekeeping means 4 non-selected. The dial data of the selected dial buffer 2 is displayed by the display means 5. When the dial operation is completed, the clock means 4 is selected again and the display means 5 continues to display the time after the off footer.

The third threshold is a main block diagram of Haku's conventional example.

The conventional telephone shown in FIG. 3 differs from the conventional telephone shown in FIG. 2 in that a clock display key means 72 is added. When the user operates the time display key means 72, the display switching means 6 initializes the time measurement means 4 and at the same time displays the lit/open time of the time measurement means 4 on the display means 5.

Problems to be Solved by the Invention However, in the conventional telephone set shown in FIG. 2, the dial operation time is added after the off-footer, so a time longer than the actual conversation time is measured and displayed. be done. On the other hand, in the case of the third cause, when the user operates the clock instruction key at the start of a call, the call time is accurately displayed, but the user may forget to operate the clock display key means 72. However, if one forgets to operate the time display key means 72, there is a problem that 31:00 will not be displayed.

The present invention has been made in view of the above-mentioned prior art, and it is an object of the present invention to provide a telephone equipped with a display section capable of displaying a call time close to the actual call time.

Means for Solving the Problems In order to achieve this object, the telephone set of the present invention includes a timer means that starts measuring time after inputting dial data and generates an output signal after a predetermined period of time has elapsed, and a timer means that starts counting time after inputting dial data and generates an output signal after a predetermined period of time has elapsed. ringback tone detection means for detecting an I-cut tone;
It consists of a clock means that is reset by either the detection signal of the ringback tone detection means or the output signal of the timer means, starts counting time, and outputs a display signal, and a display means connected to the clock means.

Effect With this configuration, if a ringback tone occurs, the elapsed time from the ringback tone is displayed as the call time, and if the ringback tone does not occur, the dialing end is displayed as the elapsed time after a certain period of time has elapsed. Since the time is displayed as a call time, the call time is displayed close to the actual call time.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of the main parts of an embodiment of the telephone according to the present invention. In Fig. 1, ■ indicates dial key means for dial operation, and 2 indicates dial key means 1.
This is a dial buffer means for storing input data. 3 is a clock means that outputs the current time;
4 is a timer which, when initialized, outputs the elapsed time since the time of initialization. 5 is a display means for displaying the data transferred from the dial buffer means 2, the clock means 3, and the timer means 4; 6 is a display switching means that switches between the dial buffer means 2 and the clock means 3 to switch the data displayed by the display means 5; and one of the outputs of the clock means 4 is selected. Reference numeral 71 is a hook switch detection means that detects whether the hook switch is turned on or off.

Reference numeral 73 denotes a ringback tone detection means for detecting a ringback tone sent to the recipient when the other party is being called after dialing is completed, and 8 is a timer means that starts measuring time after inputting the dial and outputs a signal after a predetermined period of time. Here, the predetermined time is set to, for example, 5 seconds. Further, the timer means 8 is applied with the output signal of the ringback tone detection means 73, and the timer means 8 receives the ringback tone detection signal.
output is stopped.

The operation of the telephone configured as described above will be explained below.

The hook switch detection means 71 detects the on-footer state (
When the display switching means 6 selects the clock means 3, the dial buffer means 2 and the clock means 4 are set to non-selected states. Selected clock means 3
sends the current time data to the display means 5, and the display means 5
displays the current time. When the off-footer state 5 (telephone usage state) is detected by the hook switch detection means 71, the display switching means 6 selects the dial buffer means 2 and makes the clock means 3 and the time measurement means 4 non-selected.

When the dial key means 1 is operated in the off-footer state, dial data is stored in the already selected dial buffer means 2, and at the same time, the dial data is displayed on the display means 5. When the dial key is released, the timer means 8 is reset and starts counting time. That is, each time the dial key is released, the timer means 8 is reset and starts counting, so the timer means 8 starts counting from the last time the key is released. After dialing the subscriber number of the other party, the ringback tone detection means 7 detects the ringback tone sent from the telephone line before the expiration time of the timer means 8.
3 is detected, the clock means 4 is initialized, and at the same time, the display switching means 6 selects the clock means 4, sets the dial buffer means 2 and the clock means 3 to a non-selected state, and displays the data of the clock means 4 on the display means 5. do. At this time, timer means 8
stops outputting an output signal because the ringback tone detection signal is applied. Furthermore, if the other party picks up the receiver immediately after the telephone line is connected to the other party, the ringback tone may not be detected. in this case,
Five seconds after the dial is sent, the timer 8 means expires and a signal is output to the display switching means 6. In response to this, the display switching means 6 selects the clocking means 4, and the displaying means 5 displays the data of the clocking means 4.

Effects of the Invention As described above, the present invention provides a timer means for starting time measurement after inputting dial data, a ringback tone detection means for detecting a ringback tone arriving from a telephone line, and a detection signal of the ringback tone detection means. If the ringback tone can be detected within a predetermined time by the clocking means that is reset by one of the output signals of the timer means and starts timing, and the displaying means, the time since the ringback tone was detected. In addition, if the ringback tone is not detected within a predetermined time by the dial sending stage, the timer will operate after a certain period of time has elapsed after sending the dial, so the call time can be displayed close to the actual call time. I can do it.
