CONSTITUTION:A holding output circuit 9 outputting a holding tone in common with an alarm tone outputs an alarm tone from a speaker 7 only provided to a set main body independently of the hook-state of a handset 5 at the alarm setting time. Moreover, when an alarm tone is outputted from the speaker 7 and the handset 5 in the ON-hook state is hooked off, a liquid crystal drive control circuit 13 detects it to stop the output of the alarm tone from the speaker 7. Thus, when the handset 5 is hooked off, even while the alarm tone is outputted, the user attains dialing instantly.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention has an alarm setting function, and when the alarm setting time comes, the handset is turned on or off.
The present invention relates to a telephone device that outputs an alarm sound for a certain period of time from either or both of a speaker and a handset provided on the device body depending on the hook state.

(Prior Art) Due to recent advances in science and technology, telephone devices have changed from dial-type to button-type telephones, and have also changed to cordless telephones. Additionally, in order to meet the diversifying needs of users, devices with various functions (for example, an answering machine function, automatic dialing function, automatic answering function, etc.) are being provided. One such example is a telephone device with a liquid crystal display panel equipped with an alarm function.

This telephone device is configured to output a hold tone as an alarm sound from a speaker provided in the main body of the device and a receiving section of the handset, regardless of whether the handset is hooked or not, when the alarm setting time arrives.

(Problem to be solved by the invention) For this reason, if the alarm time comes while the user is in a call state with the handset off-hook, the handset will also output an alarm sound, which will interfere with the call. There were problems such as being exposed. Furthermore, if it is necessary to make an emergency call while the alarm sound is being output, the alarm sound must be temporarily stopped, but this operation is extremely troublesome.

The present invention was made in view of the above circumstances, and its purpose is to output the alarm sound only from the speaker installed in the main body of the device, and to turn off the handset when an emergency dialing is required. To provide a telephone device which is easy to use for a user by stopping the output of an alarm sound by hooking the telephone device.

(Means for Solving the Problems) In order to solve the above problems, a telephone device of the present invention having an alarm sound output function is provided with an alarm sound output means for outputting an alarm sound only from a speaker; and when the handset, which was in an OFF-hook state, is turned OFF-hook while the alarm sound is being output from the speaker due to the operation of the alarm sound output means; and alarm sound output stopping means for stopping the output of the alarm sound from the speaker.

(Function) When the alarm setting time comes, the alarm sound output means outputs the alarm sound only from the speaker provided in the main body of the device, regardless of the hook state of the handset. Further, when the handset which was in the ON-hook state is hooked up while the alarm sound is being outputted from the speaker due to the operation of the alarm sound output means, the alarm sound output stop means disables this. Detected and stops outputting the alarm sound from the speaker. This allows the user to turn off the handset even when the alarm sound is being output.
By hooking up to F, dial operations can be performed immediately.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

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

In the figure, the output of a hook switch 2 to which a signal from a terminal (not shown) is guided via a telephone line 1 is guided to a communication circuit 4 via a rectifier circuit 3, and is connected to the terminal of the other party. The output of the communication circuit 4 forming a communication path is led to a handset 5 and a reception amplifier 6 provided in the main body of the device. Further, the output of the handset 5 indicating the user's voice signal is sent to the telephone line 1 via the communication circuit 4, the rectifier circuit 3, and the hook switch 2. Furthermore, by turning on a hold button (not shown), a hold control signal output from the hold control circuit 8 is guided to each control input of the hold tone output circuit 9, the call circuit 4, and the receiver amplifier 6, The output of the hold tone output circuit 9 configured with MOS or the like is guided to the telephone call circuit 4 and also to the speaker 7 via the receiver amplifier 6.

On the other hand, when the alarm setting time arrives, the output 131 of the liquid crystal drive control circuit 13, which sends out a signal instructing the start of output of the alarm sound, is led to the control input of the power switch circuit 110, and outputs a hold tone that also serves as the alarm sound. It is led to the control input of the hold tone output circuit 9 and the control input of the receiving amplifier 6.

Further, the signal indicating the OFF hook from the hook switch 2 is guided to the liquid crystal drive control circuit 13, and
A liquid crystal drive control circuit 13 that sends a signal instructing to prohibit the output of an alarm sound by detecting the FF hook signal.
The output 132 of is led to the mute circuit 10. Further, the output 101 of the mute circuit 10, which sends out a mute signal based on the signal from the liquid crystal drive control circuit 13, is led to the held tone output circuit 9, and the held tone output circuit 9 outputs a mute signal based on this mute signal. , the output of the hold tone to the call circuit 4 is stopped. In addition, the output 131 of the liquid crystal drive control circuit 13
One end of the power switch circuit 11, which is led to the control input, is
The negative terminal is connected to the positive terminal of the power supply voltage CC (for example, 3V) which is connected to ground, and the other end is connected to the receiving amplifier 6.

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

In the same figure, the liquid crystal drive circuit 13 includes a keypad 22 for receiving input from a time setting key 21 for setting the current time and alarm time, and an output 221 of the keypad 22 is as follows. 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 data can be transferred between the time counter 24 and the memory 23. Further, the output of the time counter 24, which sends out a signal indicating the current time, is led to an output port 25. In addition, the output of the memory 23 indicating the set alarm time is led to the output port 25, and the output port 25 is connected to the current time input from the time counter 24 and the alarm time input from the memory 23. Make a comparison. When the two times match, one output 131 of the output port 25 sends out a signal (see FIG. 3(a)) that instructs to start outputting an alarm sound, and the other output 132 outputs an alarm sound. A signal instructing prohibition [see Fig. 3 (bl)] is sent out.

Further, the output of the hook switch detection section 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 explained with reference to the signal waveform diagrams of FIGS. 3 and 4.

During normal times when an alarm time is not set, if there is a call from the other party's terminal, the user should use the handset 5.
By turning OFF, the normal talking state is established. Further, when the user dials the handset 5 with the handset 5 off-hook, and the other party's terminal responds with the 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 rectifier circuit 3, and is sent to the handset via the call path formed by the call circuit 4. 5 (in some cases, it is also guided to the speaker 7 via the receiver amplifier 6). In this call state, when the user turns on the hold button, the hold control circuit 8
, a hold control signal is output to the call circuit 4 and receiver amplifier 6. Based on this hold control signal, the call circuit 4 connects the hold tone output circuit 9 to the rectifier circuit 3 and the handset 5.
and the receiver amplifier 6, and mutes the transmitting/receiving signals to and from the other party's terminal. Then, the hold tone such as music data stored in the hold tone output circuit 9 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 and the user of the device in priority to the send/receive signal.

Next, the case where the alarm operation time is set using the time setting key 21 will be explained.

At this time, the time counter 24 has the time setting key 21
Based on this input, the time counter 24 starts counting the current time, and the counted current time is sent to the output port 25. In this state, the timer time is manually set using the time setting key 21. This timer time is stored in a predetermined storage area of the memory 23 via the key board 22 and output to the output port 25.

At the output port 25, the current time from the time counter 24 and the timer time from the memory 23 are compared.

Then, the time 1 when the current time and the timer time match.
A signal (specifically, a signal that instructs to prohibit the output of an alarm sound and is referred to as a muting signal below 2) that rises to the "l" level and maintains the bell during the period TI is output from the output 132. At the same time, at time t2, which is delayed by time Tt from time 1.
At time t4, the signal 1321 rises to the HJ level, maintains this level for a period T, and changes to the rLJ level.
At time t3, which is earlier by time T4, a signal 1311 (specifically, a signal instructing to start outputting an alarm sound: hereinafter referred to as a switching signal) that changes to the rLJ level is sent out from the output 131. That is, the muting signal is sent out before the switching signal, and after the switching signal ends, the muting signal ends.

Next, each output 132 .
The operations of this telephone device when the muting signal 1321 and the switching signal 1311 are output from 131 are as follows: ■ When the alarm time comes, the handset 5 is in the ON hook state; ■ When the alarm time comes. The case where the handset 5 is in the OFF-hook state and (2) the case where the handset 5 is switched from the ON-hook state to the OFF-hook state while the alarm sound is being transmitted will be explained separately.

■When the handset 5 is in the ON-hook state when the alarm time arrives.

In this case, a switching signal 1311 is output from the output 131 of the liquid crystal drive control circuit 13 at time t2, and is applied to the power switch circuit 11, the hold tone output circuit 9, and the receiver amplifier 6.

First, in the power switch circuit 11, the circuit is turned on by this switching signal 1311, and the power supply voltage V
cc is applied to the receiving amplifier 6. Next, in the hold sound output circuit 9, the switching signal 1311 puts the circuit into an operating state, and the hold sound stored in the hold sound output circuit 9 is output to the receiving amplifier 6. At this time, the hold tone is also output to the call circuit 4, but since the call circuit 4 is in an inactive state in this case, the hold tone is not output to the handset 5. Since the circuit is operated by the switching signal 1311, the held tone output circuit 9 supplies the held tone to the speaker 7, and the speaker 7 outputs the held tone which is an alarm sound. The power switch circuit 11, hold tone output circuit 9, and receiver amplifier 6 to which the switching signal 1311 is applied operate in an open period T during the rHJ level of the switching signal 1311, and change to the "I," level. Since the operation is stopped at time t, the speaker 7 outputs a hold tone, which is an alarm sound, only during period T. In addition, the switching signal 1
Period T from time t2 when 311 is output, time t just before
, from the output 132 of the liquid crystal drive control circuit 13,
The muting signal 1321 is output, but since the communication circuit 4 is in an inactive state as described above, the muting signal 1321 in this case has a configuration that does not substantially affect the circuit operation. It becomes.

■When the handset 5 is in the F-hook state when the alarm time arrives.

In this case, from the output 132 of the liquid crystal drive control circuit 13, time 1. First, the muting signal 1321
Since this is output, the mute circuit 10 operates, and a mute signal is output to the held tone output circuit 9. After this,
A switching signal 1311 is output from the output 131 of the liquid crystal drive control circuit 13 at time t2, and is applied to the power switch circuit 11, the hold tone output circuit 9, and the receiver amplifier 6. At this time, the hold tone output circuit 9 does not output the hold tone to the call circuit 4 because the output of the hold tone to the call circuit 4 is muted by the mute signal from the mute circuit 10 . In other words, the configuration is such that the conversation with the other party's terminal is not interrupted. In addition, time t
! The subsequent operation is the same as in case (2) above, and period T starts from time t8.

During this time, a hold tone is output from the speaker 7.

■When the handset 5 switches from the ON-hook state to the OFF-hook state while transmitting the alarm sound.

In this case, the alarm setting time 1. After that, the handset 5 is set to O.
The operation up to the time ts (see FIG. 4) at which the FF funk occurs is the same as in the above (2), and the hold tone is output from the speaker 7. In this state, at time t, the handset 5
When the hook is set to OFF, a signal indicating the OFF hook is input from the hook switch 2 to the hook switch detection unit 26 of the liquid crystal drive control circuit 13. Based on this signal, the hook switch detection unit 26 detects the OFF hook detection signal. 2
61 [see FIG. 4(C)] is sent to the output boat 25, and the output boat 25 stops sending out the switching signal and the muting signal at time t based on this OFF hook detection signal 261. As a result, the operations of the power switch circuit 11, the hold tone output circuit 9, and the receiving amplifier 6 are stopped, and therefore the output of the hold tone from the speaker 7 is stopped. That is, by turning the handset 5 off-hook, the alarm/operation state is automatically canceled, and normal dialing operations are possible from this state.

In the above embodiment, the handset 5 is activated at the alarm setting time.
The configuration is described in which the hold tone is output from the speaker 7 even when the is in the OFF-hook state. It is also possible to configure the system to mute the transmission of hold music. Furthermore, in the above embodiment, the muting signal 132'l 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 (in the case of ■). As described above, in this case, it is possible to adopt a configuration in which the muting signal 1321 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, the sending of the alarm sound can be stopped by hooking the handset off. Unlike other telephone devices, normal dialing operations can be performed without having to stop the alarm sound.
