Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a video cassette recorder, and more particularly to a video cassette recorder capable of outputting information regarding the operation of the video cassette recorder through audio synthesis.

(Prior Art) As shown in Fig. 2, this type of video cassette recorder has a control microcomputer (■) that controls the operation of the video cassette recorder, and information (operation information) regarding the operation of the video cassette recorder. Memorized voice R
OM2, a voice synthesis circuit 3 that outputs the operation information from the voice ROM 2 as a synthesized voice signal in response to input of a command signal from the control microcomputer 1, and an amplifier that amplifies the synthesized voice signal from the voice synthesis circuit 3. 4, and a speaker 5 that outputs operation information as a sound in response to the synthesized audio signal amplified by the amplifier 4.

On the other hand, this video cassette recorder includes an audio head 6, an audio recording/reproducing circuit 7 for recording audio onto a video tape (not shown) via the audio head 6, and reproducing audio recorded on the video tape, and an RF converter 8. The reproduced audio signal from the audio recording/reproducing circuit 7 is output directly to the audio output terminal 9 and via the RF converter 8 to the RF output terminal IO.

Both output terminals9. Each IO is connected to a corresponding input terminal on a television receiver (not shown), and by being connected to each input terminal, audio is output through the speakers of the television receiver. It has become.

When a user wants to know how to operate such a video cassette recorder, the user sets the video cassette recorder to an operation guide mode. Then, the control microcomputer i responds to the input of the operation guide mode by driving the operation information output system to synthesize the operation information in the voice ROMZ in the voice synthesis circuit 3, and then synthesizes the operation information in the voice ROMZ through the amplifier 4. Audio is output from the speaker 5.

On the other hand, in the playback mode for playing back the audio recorded on the videotape, the control microcomputer 1 responds to the input for the playback mode, plays the audio recorded on the videotape through the audio head 6, and plays back the audio recording. After the reproduction processing is performed in the circuit 7, the corresponding output terminal 9. Output as playback audio from IO.

(Problem to be Solved by the Invention) By the way, since such a video cassette recorder is limited in external size, it is necessary to incorporate a large speaker 5 with excellent sound quality as the speaker 5 for providing audio guidance of operation information. Therefore, there is a drawback that it is unpleasant to listen to the guidance voice of operation information through a speaker with poor sound quality.

In addition, the playback audio is from the television receiver's speakers.
Also, the synthesized sounds are output from the built-in speakers 5, but since the video cassette recorder needs to connect its output terminals 9 and 10 to the corresponding input terminals of the television receiver, Since they are usually placed close to each other, if audio is output from each speaker at the same time, it will be very difficult to hear the audio guidance on how to operate the video cassette recorder.

The present invention has been made in view of the above-mentioned problems, and allows for comfortable guidance of operation information by making it possible to output a voice guidance on how to operate the video cassette recorder using the speaker of the television receiver. At the same time, the playback audio of the video cassette recorder output from the speakers of the television receiver and the synthesized audio about how to operate the video cassette recorder are output selectively, rather than simultaneously. By configuring the system to do so, the purpose of the present invention is to eliminate the difficulty in audible guidance of operation information due to overlapping of both voices.

(Means for Solving the Problems) In order to achieve such an object, the video cassette recorder of the present invention includes a voice synthesizing means for outputting a synthesized voice signal corresponding to information regarding the operation of the video cassette recorder; an audio reproducing means for reproducing an audio signal recorded on a videotape; a reproducing audio signal output terminal for outputting the reproducing audio signal obtained by the audio reproducing means as it is; and the audio synthesizing means and the audio reproducing means, respectively. and a switch circuit that selectively outputs one of the two audio signals in response to a switching signal from the control microcomputer. The audio signal from the audio synthesis means or the audio signal from the audio reproduction means is individually output to the audio signal dedicated terminal via the switch circuit in response to a switching signal given from the control microcomputer, respectively. It is characterized by

(Operation) The audio synthesizing means outputs a synthesized audio signal corresponding to information regarding the operation of the video cassette recorder, and the audio reproducing means outputs a reproduced audio signal for the video tape.

In response to a switching signal given from the control microcomputer in the operating method guidance mode, the switch circuit outputs one of the audio signals from the audio reproducing means or the audio synthesizing means, respectively.
One audio signal is selectively output to the audio signal dedicated terminal.

Therefore, by connecting the audio signal dedicated terminal to the corresponding input terminal of the television receiver, it is possible to output information regarding how to operate the video cassette recorder using the speaker of the television receiver, and
When the information is output from the speaker, the reproduced audio from the videotape is not output from the speaker at the same time, making it very easy to hear the information.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a circuit diagram of a video cassette recorder according to an embodiment of the present invention, and the same parts as in FIG. 2 according to the conventional example are given the same reference numerals, and the parts related to the same reference numerals are explained below. is omitted.

The characteristic configuration of the video cassette recorder of this embodiment is as follows.

That is, in the video cassette recorder of this embodiment, a synthesized audio signal and a reproduced audio signal are applied from the audio synthesis circuit 3 and the audio recording/reproducing circuit 7 as audio reproducing means to the individual contacts 11a and Ilb, respectively. , of both audio signals, the movable terminal Inc is connected to one of the individual contacts in response to a switching signal from the control microcomputer l, so that one of the audio signals (in the playback mode, the playback sound signal, the operation Synthetic voice signal when in method guidance mode)
The switch circuit 11 selectively outputs the audio signal from the audio recording/reproducing circuit 7 or the audio signal from the audio synthesis circuit 3 through the switching circuit 11 depending on the playback mode and the guidance mode. The reason is that the signal is configured to be output to the signal-dedicated terminal 12.

In the video cassette recorder of this embodiment having the above configuration, by connecting the audio signal dedicated terminal 12 to the corresponding input terminal of the television receiver, the reproduced sound and operation can be performed using the speakers of the television receiver. At the same time, when the audio of the operating method is output from the speaker, the playback audio from the videotape is not simultaneously output from the speaker, making it very difficult to hear the information about the operating method. It becomes easier.

Also, 9. IO is a playback audio signal output terminal, and this output terminal 9. The synthesized audio signal is not output from the IO, but is used, for example, in dubbing mode.

(Effects of the Invention) As is clear from the above explanation, according to the present invention,
Since audio guidance on how to operate the video cassette recorder can be output using the television receiver's speakers, the operating information can be comfortably heard by using the television receiver's speakers with excellent sound quality. At the same time, the speaker of the television receiver outputs the playback audio of the video cassette recorder and the synthesized audio about how to operate the video cassette recorder, rather than simultaneously, so that the two sounds overlap. As a result, it is possible to solve the problem of difficulty in hearing the guidance of operation information.
