2. Description of the Related Art Conventionally, when a cordless telephone receives an incoming call from a telephone line (station line), both the base unit and the handset ring at the same time. It was annoying to me. In order to solve this, as in Japanese Patent Laid-Open No. 4-13749, in the master unit of a cordless telephone, the ringing order of each slave unit is stored in association with the identification code of each slave unit, and first when an incoming call arrives. When it rings, the identification number is sent to the set slave. If the first set slave does not respond, the second
The identification code of the second set slave was sent out.

However, in this example, the order, the number of times, the time, etc. of the incoming call are set collectively by the master unit, and therefore the changes cannot be easily made, and the master unit cannot be changed. And the child device needed control to exchange data, and the system was complicated.

[0004]

In order to solve this drawback, the invention has the following structure. The cordless telephone main unit and the cordless handset are provided with a storage unit for storing the ringing delay time, a timer unit for counting the end time, a ringing unit, and a control unit for controlling these, and this timer unit is provided when an incoming call is detected. By starting up and starting the ringing means when the end time of the ringing delay time stored by the storage means is detected, the master unit and the slave unit start ringing after the delay time set individually. Cordless phone.

FIG. 3 is a block diagram of a related portion of a cordless telephone master unit according to an embodiment of the present invention, and FIG. 4 is a block diagram of a related portion of a cordless telephone slave unit according to an embodiment of the present invention. FIG. 1 is a flow chart of the ringing sound of the master unit, and FIG. 2 is a flow chart of the ringing sound of the slave unit. In the master unit shown in FIG. 3, 1 is a telephone line, 12 is a hook switch, 13 is a voice circuit for making a voice call, 14 is an incoming call detecting unit that detects an incoming signal from the telephone line, and 21 is operation control of the parent unit. 22 is a signal control unit for exchanging signals of the handset, 23 is a storage unit for storing the ringing delay time from the time when an incoming call is detected, 24 is a timer unit for counting the end time,
Reference numeral 25 is a key input control unit, 31 is a transmission unit that sends a signal to the slave unit, 32 is a reception unit that receives a signal from the slave unit, 33 is a ringing unit that produces a ringing sound by the signal control unit 22, and 34 is ringing. It is an operation unit for storing the delay time.

In the slave unit shown in FIG. 4, 41 is a transmitting unit for sending signals to the master unit, 42 is a receiving unit for receiving signals from the master unit, 51 is a control unit for controlling the entire slave unit, and 52 is a slave unit. A signal control unit for exchanging signals with the machine, 53 is a storage unit for storing the ringing delay time from when an incoming call is detected, 54 is a timer unit for counting the end time, 63 is a ringing sound generated by the signal control unit 52. A ringing unit 64 is an operation unit for storing the ringing delay time.

First, a normal case will be described in which the ring delay is not set in each of the master unit and the slave unit. Next, when an incoming signal arrives from the telephone line 1, the operation of ringing the incoming call of the cordless telephone master unit and the slave unit will be described with reference to FIGS. 1, 2, 3 and 4. The base unit constantly repeats the incoming call detection operation. When an incoming call signal arrives from the telephone line 1, the incoming call detector 14 detects the incoming call and sends a detection signal to the controller 21.
The control unit 21 controls the signal control unit 22 to control the transmission unit 31 of the master unit.
The receiving unit 32 forms a wireless link between the master unit and the slave unit. When the wireless link is established, the control unit 21 of the base unit does not set the ringing delay in the storage unit 23, and therefore the signal control unit 22.
The ringing sound is generated by controlling the ringing unit 33 of the master unit via the.
Further, since a wireless link is established between the master unit and the transmitter unit 41, the receiver unit 42 of the slave unit, and the control unit 51 via the signal control unit 52, the control unit 52 of the slave unit operates the signal control unit 52. The ringing section 63 is caused to generate a ringing tone via the ringing section 63. Therefore, when an incoming signal arrives from the telephone line, the master unit and the slave unit simultaneously generate ringing sounds from the ringing units 33 and 63. However, in this case, when the wireless link cannot be established, the parent device immediately outputs the ringing unit 3
Generate ringing tone from 3.

Next, the operation of setting the ringing delay time only in the master unit will be described with reference to FIG. When the operation unit 34 is operated to select, for example, 6 seconds out of 0 seconds, 6 seconds, and 9 seconds, a data signal is sent from the key input control unit 25 to the control unit 21. The control unit 21 stores the data of the ringing delay time of 6 seconds in the storage unit 23. The setting is completed in this way.

Next, when an incoming signal arrives from the telephone line 1, the operation of ringing the incoming call of the cordless telephone master unit and the cordless handset will be described with reference to FIGS. It is assumed that the master unit has a ring delay time of 6 seconds, but the slave unit has no ring delay time. The base unit constantly repeats the incoming call detection operation. When an incoming call signal arrives from the telephone line 1, the incoming call detector 14 detects the incoming call and sends a detection signal to the controller 21. The control unit 21 controls the signal control unit 22 to form a wireless link between the master unit and the slave unit by the transmitter unit 31 and the receiver unit 32 of the master unit. When the wireless link is established, the control unit 2
1 determines whether or not the ringing delay is set in the storage unit 23. Since the ringing delay is set here, the control unit 21 delays the ringing control until the timer unit 24 times out the set time, that is, 6 seconds. When the control unit 21 detects that a time-out has occurred after 6 seconds, the ringing unit 63 is activated via the signal control unit 52 to generate a ringing tone. On the other hand, after the wireless link is established with the parent device, the child device
It is determined whether the incoming call is an internal line or an internal line. If the incoming call is an internal line, the control unit 51 checks whether the ring delay is set in the storage unit 53. Since the ring delay setting is not made here, the control unit 51 immediately controls the signal control unit 52 to cause the ring unit 63 to generate a ringing tone.

Next, the operation of setting the ringing delay time only in the slave unit will be described with reference to FIG. When the operation unit 64 is operated to select, for example, 9 seconds from 0 seconds, 6 seconds, and 9 seconds, the data signal is sent to the control unit 51. The control unit 51 stores the data of the ringing delay time of 9 seconds in the storage unit 53. The setting is completed in this way.

Next, when an incoming signal arrives from the telephone line 1, the operation of ringing the incoming call of the cordless telephone master unit and the slave unit will be described with reference to FIGS. 1 and 2. It is assumed that the slave unit has a ring delay time of 9 seconds, but the master unit has no ring delay time. The base unit constantly repeats the incoming call detection operation. When an incoming call signal arrives from the telephone line 1, the incoming call detector 14 detects the incoming call and sends a detection signal to the controller 21. The control unit 21 controls the signal control unit 22 to form a wireless link between the master unit and the slave unit by the transmitter unit 31 and the receiver unit 32 of the master unit. When the wireless link is established, the control unit 2
1 determines whether or not the ringing delay is set in the storage unit 23. Since the ring delay is not set in the master unit, the control unit 21 immediately activates the ring unit via the signal control unit 52 to generate a ringing tone. On the other hand, the slave unit is in a standby state and constantly detects a call from the master unit. After a call is made and the wireless link between the slave unit and the master unit is established, the control unit 51 determines whether it is an incoming call to a local line or an internal line. If the incoming call is a local line, the control unit 51 sets a ring delay in the storage unit 53. Check whether or not. Since the ringing delay is set here, the control unit 51
Delays the ringing control until the set time is timed out by the timer unit 54, that is, 9 seconds. When the control unit 51 detects that the time-out has occurred after the elapse of 9 seconds, the ringing unit is activated by the signal control unit 62 to generate a ringing tone. When the call from the master unit to the slave unit is an extension call, the control unit 51 immediately causes the ringing unit 63 to generate a ringing tone.

In the above description, the embodiment in which the master unit and one slave unit are used has been described. However, even if there are a plurality of slave units, it is possible to similarly set the ring delay for each slave unit. For example, one slave unit may be set for 6 seconds, the other unit may be set for 9 seconds, and the ringing delay may not be set for another unit.

[0013]

In the cordless telephone system according to the present invention, which starts individual ringing, when the incoming signal arrives from the telephone line, a ringing sound is generated after a delay time set by the user for the master unit and the slave unit individually. Therefore, a user who has set a long delay time will not be disturbed by a ringing sound each time a call is received. Further, since the delay time is set independently for the master unit and the slave unit, no control signal is exchanged between the master unit and the slave unit for ringing, so that the configuration can be easily performed.
