[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings using a cordless telephone as an example. FIG. 1 is a diagram showing the configuration of the master unit (1), and (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 being supplied to. Reference numeral (5) is a transmission circuit to which a voice signal from the telephone line (L) is supplied via the network circuit (4) and is configured to be transmitted to the slave unit (2). (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 master unit, which detects 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 circuit (4) is closed to connect the telephone line, and the dial signal is generated based on the telephone number data and controlled to dial. FIG. 2 is a diagram showing the configuration of the slave unit (2), in which (8) is a receiving circuit that receives a signal from the master unit (1), and the received signal is an electronic volume (9) and an amplifier (10). ), And the voice is amplified through the receiving speaker (11). It should be noted that the electronic volume (9) can set the volume level to, for example, five levels, and the level 1, 2, 3, 4, 5, 1, 2, ... Change the level one step in the order of. (12) is a transmission circuit that transmits the signal from the slave unit (2) to the master unit (1), and the output signal of the transmission microphone (13) and the output signal of the control circuit (19) are supplied. Has been done. (14) is a ringing tone generating circuit that generates two types of ringing tones, "melody" and "ringer". It is activated by the H signal from the output O2 of the control circuit (19) and the H from the output O3. The signal switches to "melody" and the L signal switches to "ringer". (15) and (16) are analog switches connected to the ringing tone generating circuit (14), which are turned on when the H signal is applied to the control terminal. (17) is an inverter, and (R1) and (R2) are volume adjusting resistors having different resistance values. The resistor (R1) is for "standard" and the resistor (R2) is for "loud". (18) is a speaker for calling. Reference numeral (19) is a control circuit for controlling the entire slave unit, which is based on a key signal from a keyboard (23) composed of a ten-key (20), a call key (21) and an end key (22). ) To control signals and dial signals.

FIG. 3 and FIG. 4 show flowcharts of the main program written in the control circuit (19) of the slave unit (2), and the operation will be described based on this.

First, after the power is turned on, as an initial setting, the control circuit (19) sets the electronic volume (9) to “volume level 3”, the tone color of the ringing tone generation circuit (14) to “ringer”, and When two pulses are output from the output O1 so that the ringing volume is set to "standard", an L signal is output from the outputs 03 and 04 (step S-1). In this state, when the master unit (1) detects a bell signal and sends a signal for instructing the slave unit (2) to call, the control circuit (19) outputs an H signal from the output 02 to generate a ringing sound. The circuit (14) is driven (steps S-2 and 3). As a result, the "ringer" signal is supplied to the speaker (18) via the analog switch (15) and the resistor (R1), and the "ringer" sound is reproduced at the standard volume. When the call key (21) is operated to respond to this call, the control circuit (19) sends a control signal instructing the response to the master unit (1) (steps S-4, 5). ), The control circuit (7) of the master unit (1) controls the network circuit (4) to establish a line connection. As a result, since the bell signal is stopped, the control circuit (19) changes the output O2 to the L signal and stops the operation of the ringing tone generation circuit (14) (step S-6). The call between the person at machine (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).

When the call key (21) is operated again during a call, the control circuit (19) outputs one pulse from the output O1 to the electronic volume (9) each time, and the speaker (18) ) Is changed (steps S-9 and 10). The reason why the volume of the speech force (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 in progress and there is no operational problem (end key). (22) may be used to end a call, and the numeric keypad (20) may be used for remote control). When the call ends and the end key (22) 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 master unit (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). If the call key (21) is operated, a line connection request signal is sent to the master unit (1), and if the ten key (20) is subsequently operated, dial number data is sent to the master unit (1). Then, the process proceeds to step S-9 (steps S-14 and 15). If the end key (22) is operated before the dial transmission 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) operates the "0" key and the "1" key of the ten keys (20). It is detected whether or not it has been touched (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 contents 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 the H signal from the output O2 for 1 second. Is output to drive the ringing tone generation circuit (14), and the ringing tone is generated from the speaker (18) (sub S-19, 20, 23, 24). As a result, it is possible to know the tone and volume of the ringing tone that is currently set, and also to know the timing of releasing the key operation. Next, if the operated key is the "0" key, the output signal of the output O3 is changed (L signal to H signal, or H signal to L signal), and the tone color of the ringing tone generation circuit (14) is changed. It is changed (step S-21). If the operated key is the "1" key, the output signal of the output 04 is changed (L signal to H signal, or H signal to L signal), and the ringing volume of the speaker (18) is changed ( Subup S-26). After the processing of step S-21 or step S-26, the control circuit (19) again outputs the H signal from the output O2 for 1 second to drive the ringing tone generating circuit (14), and A ringing tone is generated from the speaker (18) (step S-27). Then, the content of the timer is cleared and the process proceeds to step S-2 (step S-28). In this way, the tone color or 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 of is also notified, it is easy to recognize the amount of change, especially for the volume.

In the above-described embodiment, when the operation time of the “0” key or the “1” key reaches 3 seconds or more, the volume or tone of the ringing tone is changed. In the so-called standby mode (on-hook state for ordinary telephones), the time may be longer than the time for erroneous operation (generally about 1 to 2 seconds). Further, in the above embodiment, if the ringing 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. Therefore, a more preferable cordless telephone can be provided.

[Effect of the invention]

 As described above, according to the present invention, since the volume or / and the tone color 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, and the size of the telephone 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 numeric keypad.
