Abstract

PURPOSE:To provide talking and recording functions with simple constitution by providing a connection terminal connected to an input section of an external recorder to a telephone set. CONSTITUTION:The talking and recording preparation state is formed by connecting a connection terminal 17 connected to a telephone set 10 to a line-in connection section as an input section of a tape recorder section 19 provided to a cassette tape recorder 18, the talking and recording state is formed by using a recording switch 21 to connect the connecting terminal 17 and the telephone line 11. A transmission electric signal and a reception electric signal, that is, the content of talking is taken in by the recorder section 19 under the talking and recording state to apply the talking and recording.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a telephone equipped with a call recording function.

[Prior Art] Conventionally, in order to record the contents of a telephone call, a telephone pickup device and a tape recorder were prepared.

One end of the pickup device is attached to a telephone set, and the other end is connected to a tape recorder to record a call.

[Problems to be Solved by the Invention] However, the above-mentioned conventional call recording method requires a telephone pick-up device and requires work to attach the pick-up device to the telephone each time a call is recorded. , the management and handling of telephone equipment for recording telephone calls is complicated.

Incidentally, Japanese Patent Application Laid-Open No. 53-117915 discloses a telephone recording device which is integrally connected to a telephone set and is capable of recording the output of the telephone set. However, in this case, it is necessary to prepare a dedicated telephone recording device for the telephone and to always integrally connect them, resulting in the disadvantage that the overall shape of the telephone and the telephone recording device becomes larger.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone that can be equipped with a call recording function with a simple configuration.

Means for Solving Problem E] The telephone according to the present invention includes a connection terminal connected to an input section of an external recording device, and an attenuation shrine between the connection terminal and the communication circuit. This is how it was done.

[Function] According to the present invention, it is possible to obtain a call recording state by connecting the connection terminal to an external input section such as a cassette tape recorder with a radio. Under this call recording state, it becomes possible to capture the transmitted and received electrical signals, ie, the contents of the call, into the recording device and record the call. Thus, according to the present invention, a telephone pick-up device or a dedicated telephone recording unit can be used to record a single call! Ie
By using an arbitrary external recording device in combination without managing or handling the device, it is possible to obtain a telephone that can be equipped with a call recording function with a simple configuration.

[Embodiment] FIG. 1 is a circuit diagram showing a telephone IO according to an embodiment of the present invention.

The telephone IO has a telephone line 11, a hook switch 12,
Through the rectifier 13, a communication circuit 14, a transmitter 15, and a receiver 16 can be connected.

The hook switch 12 is closed in response to the usage status of the transmitter 15 and/or the receiver 16, and enables the communication circuit 14 to be connected to the telephone line 11. Transmitter 15
When the handset 16 and the handset 16 are integrated, the hook switch 12 closes in response to the use of the handset 15 and the handset 16, and when the handset 15 and the handset 16 are separated, the hook switch 12 closes. , the hook switch 12 is closed in response to the use of either the transmitter 15 or the receiver 16. The telephone circuit 14 transmits the transmitting electric signal generated by the transmitter 15 to the telephone line 11 and transmits the receiving electric signal sent via the telephone line 11 to the receiver 16 with as little loss as possible and good transmission characteristics. At the same time, the electric signal (sidetone) transmitted to the receiver 16 of the transmitter electric signal generated by the transmitter 15 is minimized to ensure a good conversation.

The telephone 10 includes a connection terminal (pin terminal) 17. The connection terminal 17 is connected to the line-in connection section 2 as an input section of a tape recorder section 19 provided in, for example, a cassette tape recorder with radio 18 as an external recording device.
0 (or the microphone connection part).

The telephone 4110 also includes a recording switch 21. The recording switch 21 connects the connection terminal 17 to the communication circuit 14.
It can be connected to the middle part of the receiver connection line.

22 is '##, an attenuator. The attenuator 22 enables the communication signal from the telephone line 11 to be transmitted to the cassette tape recorder 18 with a radio at an appropriate level without transmitting the noise of the cassette tape recorder 18 with a radio to the telephone line 11 side.

Note that the connection terminal 17, attenuator 22, and recording switch 21 may be connected to an intermediate portion of the connection line between the rectifier 13 and the communication circuit 14, which is indicated by A in FIG.

Hereinafter, the operation of the above embodiment will be explained.

According to the above embodiment, the call recording preparation state is established by connecting the connection terminal 17 to the line-in connection section serving as an input section of the tape recorder section 19 provided in the cassette tape recorder with radio 18, and furthermore, the call recording preparation state is established. By connecting the connection terminal 17 and the telephone line 11 using the switch 21, it becomes possible to obtain a call recording state. Under this call recording state, it becomes possible to capture the transmitted and received electrical signals, ie, the content of the call, into the tape recorder section 19 and record the call. As a result, the above phone 4
According to 1ilO, a call recording function can be achieved with a simple configuration by using a cassette tape recorder 18 with a radio as an external recording device, without managing or handling a telephone pick-up device or a dedicated telephone recording device. It becomes possible to have the following.

[Effects of the Invention] As shown in L below, the telephone according to the present invention includes a connection terminal connected to the input section of an external recording device, and an attenuator between the connection terminal and the communication circuit. This is what happened. Therefore, it is possible to provide a call recording function with a simple configuration.
