Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone, and particularly to a telephone with a call recording function, which is equipped with a recording/playback device and is capable of recording the contents of a call.

[Conventional technology]

Conventionally, the content of a call is recorded, and later the recording and playback device is operated to play it back by a predetermined operation.
There are telephones equipped with a call recording function that allows you to check the recorded content by outputting it to a speaker circuit.

[Problem that the invention seeks to solve]

However, in terms of confirming the content of a call, it is not limited to playing it through the speaker, but in some cases, it may be necessary to send the content to the telephone line so that the content can be confirmed with each other or necessary information can be conveyed to the other party. Furthermore, in that case, from the viewpoint of maintaining confidentiality, it may be desirable to reproduce and transmit only the contents of the call, or conversely, there may be cases in which it is desired to reproduce and transmit any recorded portion. In that case, if different operations are required for each case, it is not only complicated but also prone to erroneous operations.

[Means for solving problems]

In order to solve these problems, the present invention includes a line sending circuit that sends out a reproduced signal to a telephone line, and furthermore, allows recording of the current call with the other party by operating a specific operator during call recording. Select reverse transmission mode, which plays back only the content of , a means for selecting the speaker playback mode by operating a specific operator during on-hook, and when reverse transmission mode is selected, controlling the recording and playback device and line sending circuit to perform reverse transmission, and switching to line reproduction mode. When the mode is selected, the recording/playback device and the line sending circuit are controlled to perform line playback, and when the speaker playback mode is selected, the recording/playback device and the speaker circuit are controlled to perform the speaker playback. It was established.

[Effect]

No matter what playback mode you desire, just operate the same controls and the operating mode will be automatically determined based on the conditions at that time, making operation extremely easy and eliminating the risk of erroneous operation. .

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, reference numeral 11 denotes a tone ringer circuit, which is connected to the office line terminal L as shown in the figure when on-hook, and when an incoming call is received, this is notified through the speaker 12. When the handset 13 is picked up, the switch HS ₁ switches and the call circuit 1 is switched on.
4 is connected to the office line terminal L, making it possible to make a telephone call.
It is also possible to make a call using the dial circuit 15.

On the other hand, 16 is a control circuit equipped with a well-known CPU.
Controls the recording and playback system. Next, this will be explained using the flowcharts shown in FIGS. 2 to 6.

First, the control circuit 16 resets the flag indicating that the call recording mode is in progress (step 1).
201), with all analog switches 17, 18, and 19 turned off (step 202), it waits for an operation to instruct a recording/playback operation. When the button instructing call recording is pressed in this state, the control circuit 16 detects this through the call recording switch _SW1 (step 203) and shifts to a recording operation (step 204). Similarly, when the button instructing playback is pressed, the control circuit 16 detects this with the playback switch SW ₂ (step 205) and enters playback operation (step 206), and when the stop button is pressed, the stop switch is activated. SW ₃ detects this (step 207) and shifts to a stop operation (step 208).

Therefore, the control circuit 16 that has transitioned to recording operation,
As shown in Figure 3, first switch HS ₂
After confirming that the input from the terminal is at the "H" level to indicate an off-hook state, in other words, a talking state (step 301), a call recording mode flag is set (step 302). Next, the control circuit 16 causes the cassette deck 21 to perform a recording operation via the deck controller 20, and at the same time sends a signal of a specific frequency from a predetermined oscillator (not shown in the diagram) to the head 22 to record the recording start position on the recording tape. (Step 303). Next, the control circuit 16
The call is recorded by turning on the analog switch 17 (step 304) (step 305). That is, voice signals arriving at the telephone line and voice signals sent to the telephone line are transmitted to the head 22 via the amplifier 23. In addition,
C ₁ is a DC blocking capacitor, and R ₁ is a resistor.

To end the recording, press the stop button as described above, and the control circuit 16 will stop the recording operation of the cassette deck 21 as shown in FIG. 4 (step 401), and then start executing step 201. Transition.

On the other hand, when the playback operation is started, the control circuit 16 first checks whether it is in an off-hook state or an on-hook state as shown in FIG. It is checked whether the middle flag is set (step 502), and if it is set, the analog switch 17 is turned off (step 503).
Recording the recording end position on the tape (step
504). On top of that, the control circuit 16 connects the cassette deck 2
1 is rewinded (step 505). and,
When the signal indicating the start position is detected by the recording start position detection circuit 24 (step 506), the analog switch 18 is turned on (step 506).
507), and the cassette deck 21 is operated for reproduction (step 508). The reproduced signal is sent from the head 22 via the amplifier 25 to the telephone line. Thereafter, when a signal indicating the end position is detected by the recording end position detection circuit 26 (step 509), the deck operation is stopped (step 510) and the analog switch 18 is turned off (step 511). In this way, a reverse call is performed in which only the current call with the other party is sent to the telephone line.

On the other hand, if the call recording mode flag is not set (step 502), the control circuit 16
Immediately, the analog switch 18 is turned on (step 521), and the deck is operated for reproduction (step 522). If the tape is set in advance at a desired position during off-hook, that portion will be played back and sent to the telephone line. In other words, line regeneration is performed.

Furthermore, if it is on-hook (step 5)
01), the control circuit 16 turns on the analog switch 19 (step 531), and causes the deck to perform a reproducing operation (step 532). The reproduced signal is output from the head 22 via the amplifier 27 and from the speaker 28. In other words, speaker reproduction is performed.

In this manner, when the playback button is pressed, the control circuit 16 determines the setting conditions for the call recording mode, that is, in this embodiment, whether the call recording mode flag is set or reset, and the conditions for the hook switch, that is, the on-hook state. Depending on whether the device is in the off-hook state or not, the next operating mode is selected as reverse transmission mode, line playback mode, or speaker playback mode, and the deck and other functions are controlled according to the selection result. The determination procedure for selecting this operation mode is summarized in FIG. 6.

〔Effect of the invention〕

As explained above, according to the present invention, in addition to the speaker circuit, by adding a circuit for transmitting the reproduced audio from the recording and reproducing device to the telephone line, in addition to the speaker reproduction mode, the reverse transmission mode and the line reproduction mode can be set. By adding modes and making it possible to select these modes automatically depending on the conditions during playback operation, you can use each of these functions freely and easily depending on the purpose. This allows you to take full advantage of the call recording function.
