By hooking, dial operation can be performed immediately.

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

FIG. 1 is a block diagram showing the electrical connection of the telephone device of the present invention.

In the figure, the output of the hook switch 2 to which a signal from a partner terminal (not shown) is guided via the telephone line 1 is guided to the call circuit 4 via the rectifier circuit 3, and is connected to the partner terminal. The output of the speech communication circuit 4 forming the speech communication path is guided to the handset 5 and the reception amplifier 6 provided in the main body of the apparatus. The output of the handset 5 indicating the voice signal of the user is sent to the telephone line 1 through the call circuit 4, the rectifier circuit 3 and the hook switch 2. Also, by turning on the hold button (not shown),
The hold control signal output from the hold control circuit 8 is led to each control input of the hold sound output circuit 9, the communication circuit 4 and the reception amplifier 6, and the hold sound output circuit 9 configured by C-MOS or the like. The output is guided to the communication circuit 4 and also to the speaker 7 via the reception amplifier 6.

On the other hand, when the alarm set time comes, the output 13 of the liquid crystal drive control circuit 13 that sends out a signal instructing to start the output of the alarm sound
1 is led to the control input of the power switch circuit 11, and also to the control input of the holding sound output circuit 9 and the control input of the receiving amplifier 6 for outputting the holding sound that also serves as the alarm sound. Further, the signal indicating the OFF hook from the hook switch 2 is guided to the liquid crystal drive control circuit 13 and
An output 132 of the liquid crystal drive control circuit 13, which outputs a signal instructing the output of the alarm sound by detecting the OFF hook signal, is guided to the mute circuit 10. Further, the output 101 of the mute circuit 10 which sends out the mute signal based on the signal from the liquid crystal drive control circuit 13 is the hold sound output circuit 9
The hold sound output circuit 9 stops outputting the hold sound to the communication circuit 4 based on the mute signal.
Further, one end of the power switch circuit 11 to which the output 131 of the liquid crystal drive control circuit 13 is led to the control input is connected to the plus terminal of the power supply voltage V _CC (for example, 3V) whose negative terminal is connected to the ground, and The other end is connected to the reception amplifier 6.

FIG. 2 shows a more specific circuit configuration of the liquid crystal drive circuit 13.

In the figure, the liquid crystal drive circuit 13 includes a key input port 22 for receiving an input from a time setting key 21 for setting the current time and the alarm time, and the output 221 of the key input port 22 is It is led to a memory 23 for storing the set alarm time and a time counter 24 for counting the current time. The time counter 24 and the memory 23 are bidirectionally connected, and the time counter
The data transfer between the memory 24 and the memory 23 is possible. The output of the time counter 24, which outputs a signal indicating the current time, is led to the output port 25. Also,
The output of the memory 23 indicating the set alarm time is led to the output port 25, and the output port 25 compares the current time input from the time counter 24 with the alarm time input from the memory 23. To do. When the two times coincide with each other, one of the outputs 131 of the output port 25 outputs a signal (see FIG. 3 (a)) for instructing the output of the alarm sound, and the other output 132 outputs the alarm sound. A signal instructing prohibition [see FIG. 3 (b)] is transmitted. The output of the hook switch detection unit 26 that detects the OFF state of the hook switch 2 is led to the output port 25.

Next, the operation of the telephone device having the above configuration will be described with reference to the signal waveform diagrams of FIGS. 3 and 4.

In the normal time when the alarm time is not set, when a call is made from the other terminal, the user sets the handset 5
By hooking off, the normal call status is established.
Also, when the user makes an OFF hook on the handset 5 to dial, and the other terminal responds to this and makes an OFF hook, the normal call state is established.

In this case, the call signal from the other party's terminal is guided to the call circuit 4 via the telephone line 1, the hook switch 2 and the rectifying circuit 3, and the handset is provided via the call path formed by the call circuit 4. 5 (in some cases, it is also guided to the speaker 7 through the reception amplifier 6). In this call state, when the user turns on the hold button, the hold control circuit 8 outputs the hold sound output circuit 9,
The hold control signal is output to the call circuit 4 and the reception amplifier 6. Based on this hold control signal, the call circuit 4 connects the hold sound output circuit 9 to the rectifier circuit 3, the handset 5 and the earphone amplifier 6, and mutes the send / receive signal to / from the partner terminal. Then, the hold sound output circuit 9
The hold tone of the music data or the like stored in is sent to the rectifier circuit 3, the handset 5 and the receiver amplifier 6 via the call circuit 4. As a result, the hold tone is sent to the other party of the call and the user of this device in preference to the send / receive signal.

Next, a case where the alarm operation time is set by the time setting key 21 will be described.

At this time, the current time is input to the time counter 24 from the time setting key 21, and the time counter 24 starts counting the current time based on this input, and the current time counted is the output port 25. Sent to. In this state, the timer time is entered using the time setting key 21. This timer time is the key input port 22
By being stored in a predetermined storage area of the memory 23, the data is output to the output port 25.

At the output port 25, the current time from the time counter 24 is compared with the timer time from the memory 23. Then, at time t ₁ when the current time and the timer time match, a signal that rises to the “H” level and maintains this level for the period T ₁ (specifically, a signal for instructing output of an alarm sound: It is called a muting signal.) 1321
It sends out the output 132, the time T from the time t ₁
In ₂ delayed by a time t ₂ rises to "H" level, and maintained for a period T ₃ this level, the signal 1321 is "L"
A signal 1311 (specifically, a signal for instructing to start outputting an alarm sound: hereinafter referred to as a switching signal) that changes to the “L” level at time t ₃ that is earlier than time t ₄ when the level changes by time T ₄ It is sent from the output 131. That is,
The muting signal is transmitted prior to the switching signal, and after the switching signal is transmitted, the muting signal is terminated.

Next, in this way, the muting signal 1321 and the switching signal 13 are output from the outputs 132 and 131 of the output port 25 in this manner.
When the handset 5 is in the ON hook state when the alarm time comes, or when the handset 5 is in the OFF hook state when the alarm time comes, the operation of the telephone device when 11 is output is performed. During transmission, the handset 5
The case where the ON hook state is switched to the OFF hook state will be described separately.

When the handset 5 is on hook at the alarm time.

In this case, the switching signal 1311 is output from the output 131 of the liquid crystal drive control circuit 13 at time t ₂ , and is supplied to the power switch circuit 11, the hold sound output circuit 9 and the reception amplifier 6.

First, in the power switch circuit 11, this switching signal
The circuit is turned on by 1311, and the power supply voltage V _CC is applied to the reception amplifier 6. Next, in the hold sound output circuit 9, the circuit is activated by this switching signal 1311,
The hold sound stored in the hold sound output circuit 9 is output to the reception amplifier 6. At this time, the hold tone is also output to the call circuit 4, but in this case, the call tone is not output to the handset 5 because the call circuit 4 is in a non-operating state. After that, in the receiving amplifier 6, since the circuit operates by the switching signal 1311, the holding sound guided from the holding sound output circuit 9 is supplied to the speaker 7, and the holding sound which is the alarm sound is sent from the speaker 7. To do. Note that the switching signal
The power supply switch circuit 11, the hold sound output circuit 9, and the reception amplifier 6 to which 1311 is applied operate during a period T ₃ of the “H” level of the switching signal 1311 and change to the “L” level at time t ₃ . Since the operation is stopped, the speaker 7 outputs the hold sound which is the alarm sound only during the period T ₃ . Further, at the time t _{1 which} is the period T ₂ before the time t _{2 at} which the switching signal 1311 is output, the muting signal 1321 is output from the output 132 of the liquid crystal drive control circuit 13 as described above. Since the circuit 4 is in the non-operating state, the muting signal 1321 in this case has a configuration that does not substantially affect the circuit operation.

When the handset 5 is in the OFF hook state at the alarm time.

In this case, since the muting signal 1321 is first output from the output 132 of the liquid crystal drive control circuit 13 at time t ₁ , the mute circuit 10 operates and the mute signal is output to the hold sound output circuit 9. It Thereafter, the switching signal 1311 is output from the output 131 of the liquid crystal drive control circuit 13 at time t ₂ , and is applied to the power switch circuit 11, the hold sound output circuit 9 and the reception amplifier 6. At this time, the hold sound output circuit 9 does not output the hold sound to the call circuit 4 since the sending of the hold sound to the call circuit 4 is muted by the mute signal from the mute circuit 10.
That is, the communication state with the other party's terminal is not disturbed. The operation after the time t ₂ is similar to the above case, and the holding sound is output from the speaker 7 during the period T ₃ from the time t ₂ .

When the handset 5 is ON while the alarm sound is being sent
When switching to the F hook state.

In this case, after the alarm setting time t ₁ , the handset 5 turns off.
Operation up to time t ₅ that is hooked (refer to FIG. 4) is similar to the above, holding tone is outputted from the speaker 7. In this state, when the handset 5 is hooked off at time t ₅ , the hook switch 2 causes the liquid crystal drive control circuit to move.
Since the signal indicating the OFF hook is input to the hook switch detection unit 26 of 13, the hook switch detection unit 26 sends the OFF hook detection signal 261 [see FIG. 4 (c)] based on this signal to the output port 25. Then, based on the OFF hook detection signal 261, the output port 25 stops sending the switching signal and the muting signal at time t ₅ . As a result, the operations of the power switch circuit 11, the hold sound output circuit 9, and the reception amplifier 6 are stopped, so that the output of the hold sound from the speaker 7 is stopped. That is, the handset 5 is OF
By hooking the F hook, the alarm operating state is automatically released, and normal dial operation is possible from this state.

In the above embodiment, the handset 5 is set at the alarm setting time.
It is described that the hold sound is output from the speaker 7 even when is in the OFF hook state, but in this case, the mute signal from the mute circuit 10 causes the call circuit 10 to operate.
Not only that, the sending of the hold sound to the receiving amplifier 6 can be muted. Further, in the above-described embodiment, the configuration in which the muting signal 1321 is output from the output 132 of the liquid crystal drive control circuit 13 even when the handset 5 is in the ON hook state at the alarm time has been described. , In this case the muting signal 1321
It is possible to have a configuration in which is not output.

(Effects of the Invention) According to the telephone device of the present invention, even if the alarm sound is being sent from the speaker, it is possible to stop the sending of the alarm sound by hooking the handset OFF hook. Ordinary dial operation can be performed without stopping the alarm sound unlike the telephone device.
