Abstract

PURPOSE:To prevent the access to the automatic answering function part of a master set based on the careless operation of a slave set from being performed by making access the automatic answering function part of the master set corresponding to the feasibility/ infeasibility information of an automatic answering telephone operation when it is performed by each slave set. CONSTITUTION:The CPU 35 of the slave set 3, when detecting the depression of a functional key in a key part 33 and that of a dial key following the depression of the functional key, judges them as the automatic answering telephone operation. The CPU reads out automatic answering telephone operation feasibility/infeasibility information set on an E<2>PROM 32, and judges the feasibility/infeasibility of the automatic answering telephone operation. When it is feasible, a radio transmission/reception part 31 checks whether or not the system is being operated, and when it is confirmed that it is being operated, functional data representing the automatic answering telephone operation are transmitted to the master set 1 via the transmission/reception part 31 in operation. As a result, the master set 1 performs the automatic answering telephone operation in accordance with the functional data. When the operation of the functional key of the key part 33 of the slave set 3 is not detected, processing is completed after another processing is performed. In such a way, since the feasibility/ infeasibility of the automatic answering telephone operation is set on each slave set, the access to the automatic answering telephone function part of the master set due to the careless operation the slave set can be prevented from being performed.

Reference numeral 19 is a radio transmitter / receiver section for performing radio communication with the handset 3, 20 is a function key, 21 is an answering key for setting the cordless telephone device in an answering machine mode, 22
Is a dial key, 23 is an E ² PROM in which the ID code of the base unit 1 is stored and which can be electrically written and erased, 24
Is an amplifier that amplifies various signal sounds output to the speaker SP1, and 25 is a CPU that controls the base unit 1.

The slave unit 3 is constructed as follows. That is, 31 is a wireless transmission / reception unit that performs wireless communication with the master unit 1, and 32 is an E ² PRO that stores the ID code of the slave unit 3.
M and 33 are key units, 34 is a tone ringer that generates various ring tones and outputs them to the speaker SP2, and 35 is a CPU that controls the slave unit 3.

Here, when the answering key 21 of the base unit 1 is operated when going out, this device is set to the answering machine mode.
In such an answering machine mode, the CPU 24 of the base unit 1
Detects an incoming call coming to the line L via the incoming call detection circuit 11, it automatically responds to this incoming call by turning on the transistor Q via the dial IC 13, and drives the recording IC 18 to send a response message to the line L. Send out. After that, the message of the other party's message is sent to the cassette mechanism section 1.
Record to 6. In this way, an incoming call which is not in progress is automatically answered, and the message messages of the other party are sequentially recorded in the cassette mechanical section 16. When the answering key 21 is operated after returning home, the answering machine mode is canceled, and when the function key 20 or the like is operated, the message messages are sequentially reproduced and heard from the handset (not shown).

The answering machine function section such as the cassette mechanical section 16 of the master unit 1 can be operated by an operation from the slave unit 3 in addition to the master unit 1. That is, in this case, when the function key in the key unit 33 of the slave unit 3 and the dial key subsequently to this are operated, the CPU 35 in the slave unit 3 detects this and sets the wireless transmission / reception unit 31 as the function data.

FIG. 1 is a flow chart showing the operation of the CPU 35 for setting whether or not the answering machine operation of the slave unit 3 is possible. That is, in this case, the CPU 35 sets whether or not the answering machine can be operated. Therefore, in the idle state, the CPU 35 confirms "N" for pressing the registration key in the key section 33, and then, in step ST2, the dial key "0". It is judged whether or not the button is pressed. When the pressing of the dial key "0" is detected and the determination in step ST2 is "Y", it means that the setting mode has been entered, and thus step ST3.
Then, in step ST4, it is determined whether the dial key "1" for detecting that the answering machine operation is possible and the pressing of the dial key "1" for setting the answering machine operation not possible are detected.

In this case, when the pressing of the dial key "1" is detected, it is determined that the handset 3 can perform the answering machine operation, and in step ST5, information indicating that the answering machine operation is possible is provided by E ² P.
It is set in the ROM 32 (setting means). When the pressing of the dial key "2" is detected, the handset 3 determines that the answering machine cannot be operated, and sets information indicating that the answering machine cannot be operated in the E ² PROM 32 in step ST6 (setting means). If the pressing of the dial key "0" is not detected and the "mode setting?" In step ST2 is "N", it means that the answering machine operation availability setting mode is not set. When the operation is detected and judged, and if this is detected, other setting processes are performed in step ST8, and the process returns to step ST1. After that, when the registration key in the key unit 33 is pressed and the determination in step ST1 becomes “Y”, each setting process ends.

In the present embodiment, an example in which one child device is accommodated in one parent device is shown, but the same is true when a plurality of child devices are accommodated. In each of the accommodated slaves, registration operation of the answering machine availability information is performed, and the information is set in the E ² PROM built in each slave.

Then, it is determined whether or not the function key in the key unit 33 is pressed and the dial key is pressed subsequently, and when the press of these keys is detected, it is determined that the answering machine is operated, and step ST
At 11, the answering machine operation propriety information set in the E ² PROM 32 is read to determine whether or not the answering machine operation is possible. In this case, if the answering machine operation is impossible, step S
The process proceeds to T15 and other processing is performed to end the processing (control means).

If it is determined from the read answering machine operation availability information that the answering machine operation is possible and the answer is "Y" in step ST11, it is confirmed in step ST12 that the wireless transmission / reception section 31 is in operation, and if it is in operation. In step ST14, the function data indicating the answering machine operation is transmitted to the base unit 1 via the operating wireless transmission / reception unit 31 (control means). As a result, the base unit 1 performs the answering machine operation according to the function data. If the operation of the function key of the key unit 33 is not detected in the handset 3, the process proceeds to step 16 to detect other keys and the like, and proceeds to step ST15 to perform other processes and ends. .

As described above, by setting the availability of the answering machine operation for each child device, it is possible to prevent the malfunction of the answering machine function of the cordless telephone device due to the careless operation of the child device.
