Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is an answering machine for recording a message from a caller on a recording medium (including simultaneous recording when a call is directly made with the caller). Regarding telephone equipment.

(Prior Art) In a conventional answering machine, the contents of a message from a caller are all recorded on a recording medium (hereinafter referred to as a recording tape). For this reason, when this recording tape is made public to a third party, if it cannot be partially made public, for example, if it contains an individual name, group name, etc., that portion should be completely erased by another means. Was there.

(Problems to be Solved by the Invention) As described above, in the conventional device, since the unpublished portion is completely erased, there is a problem that the erased portion cannot be reproduced again.

(Means for Solving Problems) The answering machine of the present invention has been made in view of the above circumstances, and in the answering machine for recording a message from a caller on a recording tape, the recording tape is used. Of 1
A call signal storage means for recording a call signal which is a message from a caller in one channel area, and a call signal recorded in the one channel area in another one channel area of the recording tape. A camouflage signal recording means for recording a camouflage signal at a location corresponding to a location to be camouflaged, and a mixing means for mixing the camouflage signal and the call signal during reproduction are provided.

(Operation) At the time of reproduction, the call signal recorded in one channel area (for example, L channel area) of the recording tape by the call signal recording means and another one channel area (for example, R channel) of the recording tape by the camouflage signal recording means. The camouflage signal recorded in the area) is mixed and output by the mixing means. As a result, the necessary portion can be camouflaged without erasing the call signal once recorded.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic block diagram of an answering machine of the present invention.

In the figure, 1 is a recording tape, 2 is an L channel recording / reproducing head (hereinafter abbreviated as L head), 3 is an R channel recording / reproducing head (hereinafter abbreviated as R head), 4
Is a reproducing amplifier, 5 is a power amplifier, 6 is a speaker, 7 is a recording amplifier, 8 is a signal generating circuit, 9 is a bias oscillating circuit, and 10 is a signal reproduced from an L channel track and an R channel track. Mixing switch for mixing signals, 11 is a changeover switch that switches appropriately according to recording mode and reproduction mode, 12 is a bias ON / OFF switch for adding a bias signal when recording a camouflage signal, and 13 is a call A bias ON / OFF switch for adding a bias signal to a call signal from a person, and a camouflage signal ON / OFF switch for recording a camouflage signal. Note that FIG. 2 shows the positional relationship between the recording tape 1 and the L head 2 and the R head 3.

Next, the operation of the answering machine having the above configuration will be described for each mode.

Call recording mode In the call recording mode, both the mixing switch 10 and the bias ON / OFF switch 12 are OFF, the bias ON / OFF switch 13 is ON, and the selector switch 11 is switched to the terminal b side.

In this switch state, a call signal, which is a message from the caller, is input to the recording amplifier 7 and, after being amplified here, superimposed on the bias signal from the bias oscillation circuit 9, and the terminal b of the changeover switch 11 is inputted. It is supplied to the L head 2 via -c and recorded on the track of the L channel of the recording tape 1.

Camouflage signal recording mode In camouflage signal recording mode, mixing switch 10 is OFF, bias ON / OFF switch 12 is ON, bias O
The N / OFF switch 13 is OFF, and the changeover switch 11 is changed over to the terminal a side.

In this switch state, the call signal recorded on the recording tape 1 is reproduced by the L head 2, and the changeover switch
It is input to the reproduction amplifier 4 via the terminal c-a of 11, is appropriately amplified by the reproduction amplifier 4 and the power amplifier 5 of the next stage, and is output from the speaker 6 as reproduced sound. While monitoring the voice call from the speaker 6, the operator turns on the camouflage signal ON / OFF switch 14 while the recording tape 1 is running through the portion to be camouflaged, and the camouflage signal created by this Is recorded on the track of the R channel of the recording tape 1.

Playback mode In playback mode, mixing switch 10 is ON, bias
Both the ON / OFF switches 12 and 13 are OFF, and the changeover switch 11 is still connected to the terminal a side.

When the recording tape 1 is reproduced in this switch state, in the portion to be camouflaged, the camouflage signal reproduced by the R head 3 from the R channel track is mixed with the call signal reproduced by the L head 2 from the L channel track. Then, in a state where the portion is camouflaged, the speaker 6 outputs the reproduced sound.

As a result, the camouflage effect can be obtained without erasing the call signal. Further, when the camouflage is not necessary, such as when the operator listens, the miking switch 10 may be turned off in the reproduction mode.

(Effects of the Invention) As described above, according to the answering machine of the present invention, it is possible to camouflage only a necessary portion without erasing the message message recorded on the recording tape.
