Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a cordless telephone device.

(Prior Art) In conventional cordless telephone devices, in order to avoid interference from other cordless telephones, the base of the own station and the handset each have a security code (security code), It is common practice to match the handset numbers and exchange this security code as data at the start of wireless communication, so that wireless communication is only possible when a match is made.

Furthermore, 1 is a reception section, 2 is a control signal detection section, 3 is an audio control section, 4 is an audio amplification section, 5 is a speaker, 6 is a dial key, and 7 is a dial that generates a dial pulse obtained by the dial key 6. A signal generator, 8 a microphone, 9 an audio amplification section, 10 a transmission section, 11 a security code generator, 12 a switch for setting the security code, and 13 a control section for sending or stopping the security code. , 14 is a call activation switch for making a phone call, 15 is a receiving section, and 16 is a voice control section.

17 is a voice amplification section, 18 is a line control section for connecting to a telephone line, 19 is a security code detection section sent from the handset section, 20 is a switch for setting the security code, and 21 is a response signal sent to the handset section. A control signal generator, 22 is an audio amplifying section, and 23 is a transmitting section.

Next, the operation will be explained.

In FIG. 3, the code generator 11 is activated by turning on the call activation switch 14.

A code generator 11 generates a code determined by a code setting switch 12. And that data is
The signal is FM modulated by the transmitting section 10 and sent to the base section (2). In one base part ■, the receiving part 15
M demodulation is performed and the signal is sent to the code detection section 19. The code detection unit 19 detects whether the code matches the code determined by the code setting switch 20. Then, it controls the voice control section 16 and the line control section 18. Furthermore, by controlling the control signal generator 21, the handset section ■
and establish the communication system of the base part ■.

(Problems to be Solved by the Invention) In the above-mentioned conventional security setting method for cordless telephones, in order to set the security code, the security code setting switches on the handset part and the base part are set to have the same code. This had the drawback that the general public could not easily set it.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cordless telephone device that overcomes the conventional drawbacks, eliminates the inconvenience of matching two independent security codes on the handset part and the base part, and satisfies the security function.

(Means for Solving the Problems) The cordless telephone device of the present invention utilizes a charging terminal, has a base section equipped with a device for sending out a preset code, and a handset section equipped with a code receiving section and a storage section. This simplifies the code settings.

(Function) According to the present invention, when the handset is charged with the base, the contents of the PIN number set using the security code switch in the base can be set simultaneously by transferring the security code to the base. This is what we do.

(Example) An example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 shows the configuration of a cordless telephone device according to the present invention. In the figure, ■ is a handset part, and ■ is a base part. Further, 24 is a receiving section, 25 is an audio control section,
26 is a control signal detection section, 27 is an audio amplification section, 28 is a speaker, 29 is a comparator, 30 is a code storage section, 31 is a code detection section, and 32 is a code generator.

33 is a code transmission control unit, 34 is a battery, 35 is a charging terminal, 36 is a dial key, 37 is a dial signal generator, 38 is a voice amplification unit, 39 is a call activation switch, 40 is a transmitting unit, 41 is a microphone, 42 4 is a receiving section, 43 is an audio control section, 44 is an audio amplification section, 45 is a line control section, 4
6 is a control signal detection section, 47 is a comparator, 48 is a code storage section, 49 is a code generator, and 50 is a code sending control section.

51 is an audio amplifying section, 52 is a code setting switch, 53 is a charging control section, 54 is a transmitting section, and 55 is a charging terminal.

Next, the operation will be explained.

The receiving section 24 receives and demodulates the radio station wave number, and transfers the audio signal to the audio control section 25 and the data signal to the control signal detection section 26. The comparator 29 is a code storage unit 30
and the control signal detection section 26 are compared.

The audio amplification unit 27 amplifies the audio signal obtained from the audio control unit 25 and converts it into sound using the speaker 28 . The security code generator 32 controls the contents of the code storage section 30 by the sending control section 33 . The dial key 36 is a control switch for a dial signal generator 37 that generates dial signals for the telephone. Microphone 41 provides an audio signal to audio amplification section 38 . The control signal detection section 46 detects the code signal obtained from the reception section 42. The code storage section 48 is set by the code setting switch 52.
Store the N-OFF signal as a code. The code transmission control section 50 controls the transmission of the code to the transmission section 54 based on a signal from the control signal detection section 46 or the charging control section 53.
