When the ten-key for dialing and the call detection circuit detect a call, the sound generating means is driven, and when the ten key is operated for a predetermined time, the volume of the setting means and / or
Alternatively, it comprises control means for driving the sound generating means for a predetermined time after changing the tone color setting.

(E) Operation The present invention is configured as described above, and the volume or / and tone of the ringing tone can be changed by the ten keys for dialing, and the result of the change can be known.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings by taking a cordless telephone as an example.

FIG. 1 is a diagram showing a configuration of the master unit (1), (3) is a receiving circuit for receiving a signal from the slave unit (2), and the received signal is a telephone line (L) via the network circuit (4). ) Is supplied to. Reference numeral (5) is a transmission circuit supplied from the telephone line (L) through the voice syngoga network circuit (4), and is configured to transmit to the slave unit (2).
Reference numeral (6) is a bell signal detection circuit for detecting a bell signal when calling from an outside line, and the detection output is supplied to the control circuit (7). (7) is a control circuit for controlling the entire base unit,
Upon detection of the line connection request signal from the slave unit (2) and the telephone number data included in the reception signal from the reception circuit (3), the switch contact (not shown) in the network circuit (4) is closed. Then, the telephone line is connected, and a dial signal is generated based on the telephone number data to control dialing.

FIG. 2 is a diagram showing a configuration of the slave unit (2), in which (8) is a receiving circuit for receiving a signal from the master unit (1), and the received signal is an electronic volume (9), an amplifier (10). ), And a loudspeaker (11) for reception is used. It should be noted that the electronic volume (9) can be set, for example, in five stages of volume level, and in order of level 1, 2, 3, 4, 5, 1, 2 ... With one pulse given from the control circuit (19). Change the level by one step. Reference numeral (12) is a transmission circuit for transmitting a signal from the slave unit (2) to the master unit (1), which supplies the output signal of the transmission microphone (13) and the output signal of the control circuit (19). Has been done. (14) is a ringing tone generation circuit that generates two types of ringing tones, "Melody" and "Ringa". It is activated by the H signal from the output O ₂ of the control circuit (19), and H from the output O ₃ The signal is “melody”, the L signal is
Switched to "Linga". (15) and (16) are analog switches connected to the ringing tone generating circuit (14), and are turned on when the H signal is applied to the control terminal. (17) is an inverter, (R ₁ ) and (R ₂ ) are volume adjustment resistors with different resistance values. The resistor (R ₁ ) is for “standard” and the resistor (R ₂ ) is for “loud volume”. (18) is a calling speaker, (19) is a control circuit for controlling the entire handset, and is a keyboard (23) composed of a numeric keypad (20), a call key (21) and an end key (22). Based on the key signal from, the control signal and the dial signal are controlled to be transmitted to the master unit (1).

2 (a) and 2 (b) show the control circuit (1) of the slave unit (2).
The flowchart of the program of the main part written in 9) is shown, and the operation will be described based on this.

First, after the power is turned on, the control circuit (19) is initially set.
Outputs two pulses from output O ₁ and outputs O so that the electronic volume (9) is set to "volume level 3", the ringing tone generation circuit (14) is set to "ringer" and the ringing volume is set to "standard". L signal is output from ₃ and O ₄ (step S
-1). In this state, the base unit (1) detects the bell signal,
When the signal for instructing the call is sent to the slave unit (2), the control circuit (19) outputs the H signal from the output O ₂ and drives the ringing tone generating circuit (14) (steps S-2 and 3). . Thus, "ringer" signal is supplied to the speaker (18) via the analog switch (15), the resistor (R _1), "ringer" sounds are reproduced at the standard volume. When the call key (21) is operated to respond to this call, the control circuit (19)
A control signal for instructing a response is to be sent to the master unit (1) (steps S-4, 5), and the control circuit (7) of the master unit (1) controls the network circuit (4) to establish a line connection. Will be done. As a result, since the bell signal is stopped, the control circuit (19) changes the output O ₂ to the L signal and stops the operation of the ringing tone generation circuit (14) (step S-6). A call between the person who is the child device (2) and the caller becomes possible. Incidentally, if the calling is stopped before the answer by the call key (21), the operation of the ringing tone generating circuit (14) is likewise stopped and the process returns to the step S-2 (steps S-7 and 8).

Then, when the call key (21) is operated again during a call, the control circuit (19) outputs one pulse from the output O ₁ to the electronic volume (9) each time, and the speaker (18) outputs. The volume is changed (steps S-9 and 10). The reason why the volume of the speaker (18) can be changed by the call key (21) is that there is no need to operate the call key (21) after a call is made and there is no support for operation (end key ( 2
2) is used to end the call, and the numeric keypad (20) may be used for remote control). The call ends and the end key (2
When 2) is operated, the control circuit (19) sends a signal instructing the end of the call to the master unit (1) (step S-11).
As a result, the control circuit (7) of the parent device (1) controls the network circuit (4) to release the line.

Next, when it is determined that there is no call in step S-2,
The control circuit (19) detects the operation of the call key (21) (step S-13). With the operation of the call key (21),
If a line connection request signal is sent to the master unit (1) and then the ten key (20) is operated, dial number data is sent to the master unit (1) and the process proceeds to step S-9 described above. (Steps S-14 and 15). If the end key (22) is operated before dialing is completed, the process proceeds to step S-12 (step S-16).

When it is determined in step S-13 that the call key (21) is not operated, the control circuit (19) determines whether the "0" key and the "1" key of the ten keys (20) have been operated. It is detected (steps S-17 and 22). If it has been operated, the built-in timer is activated (if it has already been activated, the timekeeping operation is continued), the operation time is measured, and if not, the operation proceeds to step S-28. After clearing the timed content of the timer, the process proceeds to step S-2 (steps S-18, 23, 28).

Here, if the operation of the "0" key or the "1" key is less than 3 seconds, the process proceeds to step S-2, but if it is 3 seconds or more, the control circuit (7) outputs H from output O ₂ for 1 second. Outputs a signal to drive a ringing tone generation circuit (14) and a speaker (18)
A ringing tone is generated (steps S-19, 20, 23,
twenty four). As a result, it is possible to know the tone color and volume of the ringing tone that is currently set, and to know the timing of releasing the key operation. Next, if the operated key is the “0” key, the output signal of the output O ₃ is changed (L signal → H signal or H signal → L signal) to change the tone color of the ringing tone generation circuit (14). It is changed (step S-21). If the operated key is the "1" key, the output signal of the output O ₄ is changed (L signal → H signal or H signal → L signal) and the ringing volume of the speaker (18) is changed ( Step S-2
6).

After the processing of step S-21 or step S-26, the control circuit (19) outputs the H signal from the output O ₂ again for 1 second to drive the ringing tone generation circuit (14), and A ringing tone is generated from the speaker (18) (step S-2)
7). Then, the content measured by the timer is cleared and the process proceeds to step S-2 (step S-28).

In this way, the tone and volume of the ringing tone can be changed every time the “0” key or “1” key of the numeric keypad (20) is operated for 3 seconds or more, and at that time, not only the state after the change but also the state before the change Since the state is also notified, the amount of change can be easily recognized especially in the volume.

In the above-mentioned embodiment, when the operation time of the "0" key and the "1" key becomes 3 or more tacks, the volume and tone color of the ringing tone are changed, but at this time, the slave unit is in the so-called standby mode. In the case of (on-hook state in a general telephone), the time may be longer than the time for erroneous operation (generally, about 1 to 2 seconds).

Further, in the above embodiment, if the ring tone is generated while the call key is not operated, for example, while the "0" key and the "1" key are simultaneously operated, the setting state is set at any time. Since it is possible to know, a more preferable cordless telephone can be provided.

(G) Effect of the Invention As described above, according to the present invention, since the volume or / and the tone of the ringing tone can be changed by the ten keys for dialing, it is not necessary to provide a dedicated switch for changing them. The size can be reduced. Further, since the ringing tone is generated for a predetermined time after the change, it is possible to know the result of the change even with an automatic return key such as a ten key.
