DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radio telephone device, and more particularly to a radio telephone device in which a timer function is added to the device to generate a ring tone at a set time so that the device can be used, for example, as an alarm.

2. Description of the Related Art Conventionally, there is a wake-up call service provided at a hotel, etc., which uses a regular telephone for alarm purposes.

However, this wake-up call service
It is attached to a specific PBX and cannot be used on general public lines.

Furthermore, due to the wired nature of ordinary telephones, it is not possible to carry them anywhere you like, which causes various inconveniences when used as an alarm clock.

The present invention has been made in view of the above-mentioned circumstances, and utilizes the functions inherent in wireless telephone equipment.
A timer function has been added to this, making it possible to set the ring tone generation time using a dial.
To provide a wireless telephone device that can generate a ring tone accurately at a set time even in a telephone that is not connected to a PBX extension.

Embodiments of the present invention will be described below with reference to the drawings. Note that the drawings only show blocks related to the time setting function and the ringing tone generation function, and some of the telephone's original calling functions are omitted.
First, FIG. 1 shows a wireless telephone 10 and its parent device 20.
In particular, this is a block diagram in which a timer function is added to the wireless telephone 10 side.

This wireless telephone 10 includes a switch 11 that generates a time setting command signal to distinguish it from when the other subscriber makes a call.
and a dial 12 used for time setting, which are connected to a control circuit 13. This dial 12 is a dial used in a general telephone set, and is used to send out the subscriber number of the other subscriber when calling the other subscriber. The control circuit 1
In addition to the original control function on the wireless telephone side of the wireless telephone device, which mainly controls the line with the parent device 20 at the time of calling, receiving, and ending a call, 3 also performs functions using the dial 12 when setting the time. It has the function of setting the time based on the dial signal input at the time, and controlling the sending of a ring tone when the set time comes. 1
4 is a memory connected to the output end 13c of the control circuit 13 and stores a time setting signal; 15 is the control circuit 1;
This is a timer circuit that is connected to the output end 13d of the control circuit 3 and clocks based on a clock signal that is constantly supplied from the control circuit 13. This memory 14 and timer circuit 15
A comparison circuit 16 is connected to the output end of the memory circuit 16, which compares the memory output and the timer circuit output, and outputs a match signal when the two outputs match. The output side of this comparison circuit 16 is connected to the control circuit 1.
Connected to 3. This control circuit 13 is the comparison circuit 1
When a match signal is received from 6, it drives a built-in signal oscillation source (not shown) and outputs a calling signal to the output end 13.
The data is sent to b. 34 is a ringer amplifier connected to the output end 13b of the control circuit 13 and amplifying the calling signal sent from the control circuit 13;
18 reversibly converts the voice into an audio signal and supplies it to the amplifier 17a during a call, and the control circuit 1 during a call.
19a is a transmitting circuit.

On the other hand, the parent device 20 is connected to the telephone line 21 and has a relay function for the radio telephone 10.

Next, a description will be given of the operation of the radio telephone device configured as described above, especially when a time is set and a ringing tone is generated. First, when setting the time, turn off the hook and turn on switch 11. When the switch 11 is turned on, a geosignal, for example, enters the control circuit 13, and the control circuit 13 detects this signal and then uses the dial signal to be input from the dial 12 as a signal for time setting.
A predetermined control operation will be performed.

After turning on the switch 11, set the time using the dial 12. For example, to set 6:30, press the dial 12 in the order of "0630".
Then, the dial signal "0630" enters the control circuit 13, where it is converted into a time setting signal and stored in the memory 14. After setting the time as described above, when the handset is put down, the handset is turned on, and the switch 11 is turned off, the phone enters the ring standby state for the set time and returns to its original function as a telephone.

By the way, in the comparison circuit 16, the time setting signal of the memory 14 stored by the dial 12 and the time signal of the timer circuit 15 which is clocked based on the clock signal output from the control circuit 13 are used. Constant comparison and verification. And the timer circuit 15
When the time signal matches the time setting signal, a match signal is output and input to the control circuit 13. Control circuit 1
3 drives a built-in signal oscillation source upon receiving the coincidence signal and outputs a calling signal from the output end side 13b. The ringing signal output from the output end 13b is amplified by the ringer amplifier 34, and then generated from the transmitter 18 as a ringing tone. Therefore, the general wireless telephone 10
memory 14, timer circuit 15 and comparison circuit 1
Just by adding a timer function such as 6, dial 1
2, it is possible to generate a ring tone accurately at the set time.

In the above explanation, the switch 11 is used to issue a command to set the time, but in the case of a pushphone type wireless telephone device, the time can be set by pressing a specific dial signal, for example, the asterisk symbol * twice. It may also be defined as a command signal. In this case, when the control circuit 13 receives two consecutive asterisk signals from the dial 12, it determines that it is time to set the time and enters a preparatory operation for predetermined connection changes and signal processing. Furthermore, it goes without saying that the control circuit 13, memory 14, timer circuit 15, and comparator circuit 16 can be easily implemented as a microcomputer. It can be clocked.

Therefore, in the case of the above-mentioned radio telephone device, by simply adding a simple timer function to the conventional radio telephone 10, it is possible to generate a ring tone accurately at a preset time. It can be carried freely and is very effective as an alarm clock.

Next, FIG. 2 is a diagram showing another embodiment of the device of the present invention, and the difference from FIG. 1 is that the parent device 20
It has a timer function on the side. In addition to the switch 11, dial 12, and control circuit 13, this radio telephone 10 is provided with a transmitting low frequency amplifier 17a and a receiving low frequency amplifier 17b as amplifiers connected to the control circuit 13, and further includes a transmitting low frequency amplifier 17a and a receiving low frequency amplifier 17b. The configuration is such that a transmitting circuit 19a is connected to the output side, and a receiving circuit 19b is connected to the input side of the receiving low frequency amplifier 17b. 18 is a transmitter.

On the other hand, the parent device 20 has an amplifier consisting of a transmitting low frequency amplifier 23a and a receiving low frequency amplifier 23b connected to the telephone line 21 via a line switch 22, and further has a transmitting circuit connected to the output side of the transmitting low frequency amplifier 23a. 24a, receiving side low frequency amplifier 2
A receiving circuit 24b is connected to the input side of each of the receiving circuits 3b. Further, the parent device 20 is provided with a control circuit 25, which in addition to the original control function of the parent device, controls the ON signal of the switch 11 inputted via the receiving circuit 24b and the receiving low frequency amplifier 23b. It has the function of sending a line disconnection signal to the line circuit 22, converting the signal set by the dial 12 into a time setting signal, and sending out a clock signal. 26 is a memory, 27 is a timer circuit, and 28 is a comparison circuit.

Next, the operation of the apparatus shown in FIG. 2 will be explained. First, prior to setting the time, the radio telephone 10 is turned off, the switch 11 is turned off, and, for example, an earth signal is input to the control circuit 13. Control circuit 1
3 generates and outputs a time setting command signal upon receiving the earth signal. This command signal is sent to the transmitting low frequency amplifier 1.
The signal is modulated by the transmitting circuit and sent out from the antenna via the signal line 7a.

The master device 20 receives and demodulates the command signal sent from the wireless telephone side antenna via the master device side antenna in the receiving circuit 24b.
It is input to the control circuit 25 through 3b.

Next, the dial 12 is used to set the time. For example, to set the time to 7:30, enter “0730”
Perform dial operations in this order. The dial signal output from the dial 12 enters the control circuit 13, where it is processed into, for example, an on/off tone signal.
Transmission circuit 19a via transmission low frequency amplifier 17a
is modulated and transmitted from the antenna.

The signal transmitted from the antenna on the wireless telephone side is received by the receiving circuit 24b via the antenna on the parent device side.
It is demodulated and reproduced as a dial signal. Then, this dial signal enters the control circuit 25 through the receiving low frequency amplifier 23b, where it is converted into a time setting signal and stored in the memory 26, and the timer circuit 27
The control circuit 25 sequentially clocks a clock signal from a clock signal oscillation source (not shown) built in and outputs a time signal.

In the above, explanations of the operations of the foot switch and line switch have been omitted.

By the way, the time setting signal stored in the memory 26 is compared with the time signal of the timer circuit 27,
When the set time comes, a match signal is output from the comparison circuit 28 and inputted to the control circuit 25. When this control circuit 25 receives the match signal from the comparison circuit 28, it generates, for example, a tone signal for calling control. This calling signal is transmitted from the control circuit 25 to the low frequency amplifier 23a.
The signal is guided to the transmitting circuit 24a via the antenna, where it is modulated and transmitted from the antenna.

The signal transmitted from the master device 20 is transmitted to the wireless telephone 1
The received signal is received and demodulated by the receiving circuit 19b through the antenna No. 0, and is input to the control circuit 13 via the receiving low frequency amplifier 17b. The control circuit 13 receives the ringing signal and drives the ringer amplifier 34 to transmit the transmitter 1.
A ring tone is generated from 8.

Unlike the device shown in FIG. 1, the device shown in FIG. 2 has a timer function added to the parent device 20 side, and from the perspective of the wireless telephone 10, the number of parts does not increase and the device meets the demand for miniaturization of the wireless telephone 10. It is. Furthermore, since the signals sent and received between the wireless telephone 10 and the master device 20 can use the line connection tone signal normally used when making a call to the other subscriber, the device is not as complicated as the device shown in FIG. . Further, in the case of the push-dial type, it is also possible to use an asterisk to distinguish between the time of calling and the time of time setting, as in FIG. Furthermore, it is extremely easy to replace the control circuit 25, memory 26, etc. in the parent device 20 with a microcomputer, as in FIG. In addition, when the set time is reached and a call is made, for example, if the wireless telephone 10 is malfunctioning or the wireless telephone 1
If 0 is out of communication range and cannot be called, the parent device 20 is provided with an alarm function to generate an alarm sound,
It is also possible to notify the user that it is the set time. Note that the alarm sound can also be used by a speaker for transmitting the howler sound.

Next, FIG. 3 is a diagram showing another embodiment of the present invention, in which the ring tone at the set time and the ring tone when receiving a call from the other party are generated with different tones. It is something. For example, control circuit 1
A ringing signal (clock signal) line 31 and a sound modulation signal line 32 that determines the on/off cycle of the sound are provided on the output end side of 3, and these lines 31, 32
is connected to the two input terminals of the AND circuit 33.
The output terminal of the AND circuit 33 is connected to the transmitter 18 via the ringer amplifier 34. In this figure, the same parts as those in FIG. 1 are designated by the same reference numerals, and some explanations are omitted.

First, when a call is received from the other subscriber, a ringing signal is sent to the ringing modulation signal line 32 at a cycle of, for example, a 1-second on signal and a 2-second off signal, and an AND circuit 33 performs an AND with the ringing signal to drive a ringer amplifier 34. do.
On the other hand, a call indicating that the set time has come is sent to the sound modulation signal line 32 at a cycle of, for example, a 1-second on signal and a 1-second off signal, and an AND circuit 33 performs an AND with the call signal to drive a ringer amplifier 34. do. The signal output from the ringer amplifier 34 is then generated by the transmitter 18 as a ringing tone with different tones. Of course, as means for changing the tone of the ringing tone, it is also possible to use another oscillation source or to change the frequency division ratio of the clock signal. It goes without saying that this volume variable means can be easily applied not only to the device shown in FIG. 1 but also to the device shown in FIG.

FIG. 4 is a diagram showing another example of the device of the present invention, in which the volume level is initially set low and the volume level is increased as time elapses until a predetermined volume level is reached. This is a configuration that is saturated when it reaches . in particular,
A volume level changeover switch 35 is interposed between the ringer amplifier 34 and the transmitter 18, and the volume level changeover switch 3 is connected to the control circuit 13 via a line 36.
5, a switching control signal is input to set a predetermined volume level.

FIG. 5 is an example showing how the volume level can be varied. For example, if the ring tone when a call arrives from the other subscriber is set to volume level C, the control circuit 13 detects a call from the other subscriber, inputs a switching control signal to the volume level changeover switch 35, and outputs a switching control signal to the volume level C. and continue this level C.

On the other hand, when generating a ring tone indicating that the set time has come, the volume level is increased as time passes, as shown in FIG. First, the control circuit 13 detects a coincidence signal from the comparison circuit 16 and sets the volume level changeover switch 35 to A, which is the minimum volume level.

If the ringing tone continues to be generated for _T1 hours, the control circuit 13 detects this and sends out a switching control signal to switch the volume level changeover switch 35 and set the volume level to B. In this manner, the volume level is gradually increased in accordance with the generation time of the ringing tone, and is saturated at, for example, level C, which is lower than level D at hook-off. When the volume level of C reaches T _{for 1} hour, either continue the volume level C and turn it off at an appropriate time, or
When a predetermined time _T2 has elapsed beyond _T1 hour, the ringer is turned off.

Note that the present invention is not limited to the above embodiments. For example, the time setting signal may not only be stored in the memory 14, but may also be displayed on a liquid crystal display provided in the housing of the wireless telephone 10. In addition, in the explanation of FIGS. 4 and 5, the volume level of the ringer was gradually increased as time progressed.
Needless to say, it may be increased linearly. In addition, the present invention can be modified in various ways without departing from its gist.

As detailed above, according to the present invention, a timer function is added to either the wireless telephone or its parent device, and the time is set using a dial. It is now possible to generate a ringing tone, making it easy to use not only as an alarm but also for commercial purposes. It can also generate a ring tone accurately at the set time. Moreover, the wireless telephone can be carried freely within the service area, making it very convenient to use. In addition, the control circuit and timer functions can be easily implemented on a microcomputer, which satisfies the demand for miniaturization.If the timer circuit clock uses the microcomputer's clock signal as is, the number of components can be reduced. It is possible to provide a wireless telephone device that has various effects, such as being able to achieve it without increasing the number of devices.
