[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is mainly applicable to conveying messages to others when you are away, etc., and various applications such as music, drama, news reporting, lectures, etc. The present invention relates to a telephone equipped with a built-in tape recorder and radio for use in listening to audio programs.

(Prior Art) A normal telephone consists of a telephone main body in which various parts such as a signaling device and a communication device are built-in, and a handset in which a transmitter and a handset are integrally molded. When sending a message to someone else, they would ask the Nippon Telegraph and Telephone Company to connect them to an electronic exchange line. Additionally, in order to listen to various audio programs, it was necessary to prepare a new radio.

(Problems to be solved by the invention) <Problems with the conventional technology> However, since ordinary telephones must be connected to the line of the Nippon Telegraph and Telephone Company, not only do they require permission and authorization, but the telephone Because it uses the station's power supply, there is a lack of safety, and when changing the contents of messages etc.
Each time, a request had to be made to the Nippon Telegraph and Telephone Company, which not only made the operation troublesome and not easy to use, but also lacked interest and increased costs. Furthermore, when listening to various audio programs, it is necessary to prepare a radio separate from the telephone set, which is inconvenient and increases costs.

<Technical Issues> Therefore, the present invention was created to solve the above-mentioned problems, and eliminates the need for permission and authorization by eliminating the connection to the Nippon Telegraph and Telephone Company line. In addition to eliminating the need for power from the telephone office, it is completely safe, and anyone can easily change the contents of messages, etc., making it easier to use, improving interest, and reducing costs. In addition, when listening to various audio programs, there is no need to prepare a separate radio from the telephone, making it extremely convenient and cost-saving to use a telephone with a built-in tape recorder and radio. This is what we provide.

[Structure of the Invention] (Means for Solving the Problems) The present invention is a technical means for solving the problems of the prior art, in which a microphone-equipped microphone and a speaker-equipped receiver are integrally molded. This telephone consists of a handset, a tape recorder that uses the microphone of the handset and a speaker of the handset to record, play, and erase data, and a radio that allows you to listen to various audio programs. The tape recorder inside the main body includes a switching circuit that commands recording and playback using a recording switch and a playback switch, and records and detects recording and playback signals that are commanded by the recording switch and playback switch of this switching circuit. It is formed of an audio amplification circuit, a sound sensor circuit that detects external sound pressure and instructs reproduction together with a reproduction switch of the switching circuit, and a tape cue sensor circuit that always positions the beginning of the endless tape in a starting state, On the other hand, the radio is configured such that a radio circuit for commanding various audio programs is connected between the audio amplification circuit and the power supply circuit using a radio switch.

(Function) The present invention uses the technical means described above to turn on the recording switch of the switching circuit of the tape recorder when recording a message, etc., and instruct the recording via the digital IC. By using this recording signal to put the recording/playback head into a recording state via the digital IC of the audio amplification circuit, and then, after the endless tape has rotated, by speaking a message etc. from the microphone of the handset. Messages, etc. are recorded on an endless tape, and when playing back the recorded messages, turn on the playback switch of the switching circuit and command playback via the digital IC, or use the sound sensor circuit. The microphone detects external sound pressure such as applause or human voices and commands playback, and these playback signals put the recording/playback head into a playback state via the digital IC of the audio amplification circuit. Then, after the endless tape has been rotated, messages can be heard from the speaker of the handset.On the other hand, when listening to various audio programs, turn on the radio switch of the radio circuit of the radio and turn on the radio switch of the radio circuit. An audio program is commanded, and various audio programs can be heard from a speaker via a radio circuit using the audio signal.

Furthermore, even if the recording switch 9 and the playback switch 10 of the switching circuit 11 are turned off when the beginning of the endless tape is halfway during recording and playback, the electrolytic capacitor C
Since the collector current of transistor T8 was flowing until T7.27 was charged, each transistor T7.27 was charged. T8 is OFF
Even if the current does not flow from the transistor T8, the transistor T9 remains on and the motor 28 and the endless tape continue to rotate. Thereafter, as in the normal case, only when the head of the endless tape rotates once and the insulating cut contacts the sensor inch 26, the transistor T9 turns OFF and the motor 28
The power is turned off and the beginning of the endless tape stops at the start position. Furthermore, when changing the contents of a message, etc., the previously recorded message, etc. is automatically erased by the erasing head 23 located at the front of the endless tape rotation direction of the recording/playback head 22 when making a new recording. Of course, it will be deleted.

Furthermore, to explain the operation of the radio 7, when listening to various audio programs on the radio 7, the radio switch 30 of the radio circuit 31 is turned on, various audio programs are commanded, and the audio signals are used to listen to the radio 7. Speaker 3 via circuit 3o
You can listen to various audio programs from 2.

[Effects of the Invention] As described above, the present invention provides a handset 5 in which a handset 2 with a microphone 1 and a handset 4 with a speaker 3 are integrally molded;
It consists of a telephone main body 8 in which a tape recorder 6 is incorporated, and a microphone 1 of a transmitter 2 of a handset 5 and a receiver 4.
Since messages can be recorded, played back, and erased using the speaker 3 of the tape recorder 6, it is possible to record messages, etc. on the endless tape of the tape recorder 6. Not only is there no need for any permits or approvals as there is no need to ask the operator to connect to the electronic exchange line, but there is also no need for permits or approvals, and since the 6V power supply circuit 18 is used as the power source, safety is ensured. .

Moreover, when changing the contents of a message, etc., by performing the same operation as when recording for the first time, the previously recorded message, etc. is automatically erased and a new message, etc. is recorded on the endless tape. Therefore, anyone can easily change the contents of a message, etc., without having to request the Nippon Telegraph and Telephone Company again each time as in the past. Therefore, it is not only easy to use, but also very interesting, and costs can be significantly reduced.

Furthermore, when reproducing a recorded message, etc., the operation can be performed not only by operating the reproduction switch 10 of the switching circuit 11 but also by detecting external sound pressure such as applause or human voice by the sound sensor circuit 13. , it is possible to perform a wide variety of playback operations, further increasing the level of interest.

Furthermore, when listening to various audio programs on Radio 7, it is extremely easy to operate by simply pressing the radio switch 30 on the radio circuit 31 of Radio 7, without having to prepare a separate radio from the telephone as in the past. Since you can listen to various audio programs, it is extremely convenient and can further reduce costs.
