Description

DETAILED DESCRIPTION OF THE INVENTION The present invention constantly records the output signals of a tape recorder, VTR, etc. in a separate storage device.
The present invention relates to a recording and reproducing apparatus that can instantly and repeatedly reproduce recorded contents for a certain period of time immediately before the recording when necessary.

Conventional recording and playback devices that repeatedly play back the sound of a tape recorder, for example, were recorded on an endless tape recorder and then played back by the endless tape recorder as needed. Because it has to be recorded, the endless tape wears out rapidly, and it also takes too long to rewind when switching from recording to playback, and the tape wears out during repeat playback, causing audio deterioration. There was a drawback of doing so.

The present invention solves this conventional drawback by allowing signals from playback devices such as tape recorders or VTRs whose output can be temporarily stopped.
To provide a recording/reproducing device configured to constantly store data in a solid-state storage device such as a semiconductor memory and to instantaneously reproduce the immediately previous stored content from the solid-state storage device as needed. An embodiment of the present invention will be described below based on the drawings.

The drawing is a configuration diagram showing an embodiment of the present invention.
Reference numeral 1 denotes a tape recorder, which is an example of a reproducing apparatus characterized in that when the reproduction output is temporarily stopped, the next information is not lost during the stop time. Therefore, it may be a VTR or other optical recording/reproducing device, and does not include devices that simply receive and output broadcast waves, such as a radio or television receiver. 2 is an analog-to-digital converter that converts the output of the tape recorder 1 into a digital signal. 31 and 32 are solid-state storage devices such as semiconductor memories, which store the output of the tape recorder 1 input via the analog-to-digital converter 2. 4 is a digital-to-analog converter that converts the output of the solid-state storage device 31 or 32 into an analog signal; 5 is an output terminal for selecting either the output of the digital-to-analog converter 4 or the output of the tape recorder 1; This is a selector switch that outputs to 6. Reference numeral 7 denotes an operating state switching control section, which controls the tape recorder 1 and the changeover switch 5 as shown by broken lines.
Switching switches 8 and 9 and the solid state storage device 3 switch the operation mode of the solid state storage device 31 and the solid state storage device 32 into the storage state and the read state, respectively.
Selection switch 10 for selecting 1 or 32 outputs
This is used to switch the operation mode of the

First, in the case of normal operation, the operating state switching control section 7
The tape recorder 1 is brought into operation by this signal, and the output signal of the tape recorder 1 is outputted to the output terminal 6 via the changeover switch 5. At the same time, the output signal of the tape recorder 1 passes through the analog-to-digital converter 2 and is stored in the solid-state storage device 31 or 32. The storage and read states of the solid-state storage devices 31 and 32 are switched by changeover switches 8 and 9, respectively. That is, when one of the two is in storage, the other is in read mode, and when one is in read mode, the other is in memory mode. can be switched alternately. This control is performed by the changeover switches 8 and 9 in response to a signal from the operating state changeover control section 7.

Next, in the case of repeat playback operation, the selection switch 10 selects the output of the solid-state storage device 31 or 32 that was in the storage operation state until just before, based on a signal from the operation state switching control section 7. After the signal is restored to the original signal by the digital-to-analog converter 4, it is transmitted to the output terminal 6 via the changeover switch 5. The switches 8, 9, and 10 are controlled by the operating state switching control section 8 so as to alternately reverse each time the switching switch 5 enters the repeat playback state.

According to the configuration of the above-described embodiment, it is possible to instantly check the previous content and listen to it over and over again, if necessary, while the tape recorder (or VTR) is being played back. You can easily and accurately reproduce what you have heard, what you want to write down, what you want to enjoy listening to over and over again.

At this time, in the above case, two systems of solid-state storage devices are provided, and one is always in the storage state, so the tape recorder's normal playback state and the repeat playback state by reading from the solid-state storage device are frequently switched. Also, the previous signal can always be played repeatedly. Furthermore, since the tape recorder is stopped in the repeat playback state, when switching to normal playback operation, playback starts from the position where the tape stopped and the information can be listened to without missing information.

As described above, according to the present invention, it is possible to provide an excellent recording and reproducing device that can easily perform repeated reproduction and can reproduce the immediately preceding information even if the state of normal reproduction and repeat reproduction is frequently switched. It is.
