Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having display means for displaying a call time.

2. Description of the Related Art Conventionally, there is a telephone having a means for displaying a dialed number in order to prevent a dial error, but since the dial is not required when the telephone is not in use or during a conversation, the current time display and the conversation time are There are telephones that have the function of displaying timers for measurement.

Hereinafter, a telephone having the above-described conventional display means will be described with reference to the drawings.

FIG. 2 is a block diagram of a main part of a telephone having a conventional display means. In FIG. 2, 1 is a dial key means for dial operation, 2 is a dial buffer means for storing data inputted by the dial key means 1, 3 is a clock means, 4 is a timer, 5 is a dial buffer 2 and The display means 6 for displaying the data transferred from the clock means 3 and the timer 4 is a display switching means, and selects the data to be displayed by the display means 5 from the dial buffer 2, the clock means 3 and the timer 4. Reference numeral 71 is a hook switch detecting means for detecting ON / OFF of the hook switch.

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

When the hook switch detection means 71 detects that it is in the on-hook state (telephone unused state), the display switching means 6
Selects clock means 3, dial buffer 2 and timer 4
Is deselected. The selected clock means 3 displays the current time by the display means 5. When the hook switch detecting means 71 detects that the hook switch detecting means 71 is in the off-hook state (telephone use state), the display switching means 6 selects the timer 4 and deactivates the dial buffer 2 and the clock means 3. At the same time, the timer 4 is initialized by the off-hook detection signal of 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 the off-hook state, the dial buffer 1 informs the display switching means 6 that the key operation has been performed. The display switching means 6 selects the dial buffer 2 and deactivates the clock means 3 and the timer 4.
The selected dial buffer 2 displays dial data by the display means 5. When the dial operation is completed, the timer 4 is selected again and the display means 5 continues to display the time after the off-hook.

FIG. 3 is a main block diagram of another conventional example.
The conventional example shown in FIG. 3 is different from the conventional example shown in FIG. 2 in that a timer display key means 72 is added. When the user operates the timer display key means 72, the display switching means 6 initializes the timer 4 and at the same time selects the display means 5 to display.

However, in the conventional example shown in FIG. 2 in which the timer is displayed by the off-hook signal detected by the hook switch detecting means 71 in the above-mentioned configuration, since the dial operation time is added after the off-hook, the actual operation is actually performed. More than the conversation time of. On the other hand, the timer display instruction key means 72 shown in FIG.
In the conventional example in which the timer is displayed according to the instruction, there is a problem that the user may forget to operate the timer display key means 72.

The present invention has been made in view of the above-mentioned prior art, and displays the time after the ringback tone is detected and connected to the other party after dialing, and the ringback tone is displayed within a predetermined time after the tire is sent out. Provided is a telephone with a display capable of displaying a call time very close to an actual call time even when it is not detected.

Means for Solving the Problems To achieve this object, the telephone of the present invention is connected to a telephone line, and a hook switch detecting means for detecting whether the handset is lifted or placed on the telephone body by a hook switch. And dial data input means for temporarily storing dial data input by operating the dial keys, display means for displaying various data, and display switching means for switching data to be displayed on the display means. A ringback tone detecting means for detecting a ringback tone coming from a telephone line, which is a telephone set,
The time counting is started after the dial data is input, the time counting is output when a predetermined time has elapsed, and the time counting is stopped if the ring back tone detection output is obtained from the ring back tone detecting means before the predetermined time elapses. No. 2 timer means and the ringback tone detection means obtain a ringback tone detection output, or the second timer means outputs a timing output, whichever comes first, and outputs timing data. A first timer means, and is configured to display the time measurement data of the first timer means on the display means.

Function With this configuration, the call time after the call partner picks up the call is displayed, and if the call partner cannot pick up the call, the time measured after a certain time has elapsed after dialing is finished is displayed. Therefore, the call time very close to the actual call time is displayed.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a main part in one embodiment of the present invention. In FIG. 1, 1 is dial key means for dial operation, 2 is a dial buffer for storing data input by the dial key means 1, 3 is clock means for outputting the current time, 4 is a timer, 5 is Display means for displaying the data transferred from the dial buffer 2, the clock means 3, and the timer 4, 6 is a display switching means, 71 is a hook switch detecting means, and 73 is sent to the receiver when calling the other party after dialing is completed. A ringback tone detecting means for detecting a ringback tone, 8 outputs a signal after a predetermined time (about 5 seconds) after starting dialing and counting time, but outputs a signal when the ringback tone detection signal is applied. Not the second timer.

The operation of the telephone configured as above will be described below. When the hook switch detection means 71 detects that it is in the on-hook state (telephone unused state), the display switching means 6 selects the clock means 3 and deactivates the dial buffer 2 and the timer 4. The selected clock means 3 displays the current time by the display means 5. When the hook switch detecting means 71 detects the off-hook state 5 (telephone use state), the display switching means 6 selects the dial buffer 2 and deactivates the clock means 3 and the timer 4.

When the dial key means 1 is operated in the off-hook state, the dial data is stored in the dial buffer 2 which is already selected, and at the same time the display means 5 displays the dial data. When the dial key is pressed, the second timer 8 is reset and when the dial key is released, the second timer 8 is reset.
Timer 8 starts counting time. That is, the second timer 8 starts counting the time when the last one of the plurality of dial keys is released. When the ringback tone sent from the telephone line is detected by the ringback tone detecting means 73 after the dialing of the other party's subscriber number is completed, the timer 4
The display switching means 6 simultaneously selects the timer 4, the dial buffer 2 and the clock means 3 are deselected, and the display means 5 displays the data of the timer 4. At this time, the second timer 8 does not output the time-out signal due to the ringback tone detection signal being applied.
The movement of is not disturbed. Also, if the other party picks up the handset immediately after connecting to the other party, the ringback tone may not be detected. In this case, the second timer 8 expires 5 seconds after the dial transmission and outputs a signal to the display switching means 6. In response to this, the display switching means 6 selects and activates the timer 4, and the display means 5 displays the data of the timer 4. In addition, when it takes time to connect to the other party due to multiple telephone lines, the ringback tone does not come back easily. In this case, first, the second timer 8 expires and the output signal is output. To occur. Therefore,
The display switching means 6 selectively activates the timer 4 and causes the display means 5 to display the timer. After that, when the other side is connected and a ring back tone is detected, the second timer 8 stops its operation, and the timer 4 is reset and a new time measurement is started. Therefore, the display unit 5 displays the time elapsed after the ringback tone is detected.

As described above, the telephone of the present invention is connected to the telephone line, and the hook switch detection means for detecting whether the handset is lifted or placed on the telephone body is operated by the dial switch and the hook switch detection means. A telephone having a dial data input means for temporarily storing inputted dial data, a display means for displaying various data, and a display switching means for switching data to be displayed on the display means. A ring back tone detecting means for detecting an incoming ring back tone, and a time counting start after the dial data is inputted and a time counting output when a predetermined time has passed, and a ring back tone detecting means before the predetermined time has passed. If a ring back tone detection output is obtained from the A first timer means for starting the clock and outputting the timing data when the ringback tone detection output is obtained from the clock tone detecting means or the second timer means outputs the timing output, whichever is earlier. Then, the time measurement data of the first timer means is displayed on the display means. Therefore, since the other party's off-hook after the ringback tone is detected and the timer operation is started, an accurate conversation time is measured. Furthermore, it is difficult to detect the off-hook of the other party surely because the number of cases where it is used under various private exchanges has increased due to the spread of telephones, but the timer operation starts after a certain period of time. Thus, the operation time of this timer is displayed, which has the effect of reducing the error in measuring the conversation time.

Further, in the present embodiment, the clock means is not selected when the timer is selectively displayed, but the timer and the clock can be simultaneously displayed when the display means can display them simultaneously.
