るという欠点があつた。 Conventional recording/playback devices that repeatedly play back the sound of a tape recorder, for example, are recorded on an endless tape recorder and then played back by the endless tape recorder as needed. As a result, the endless tape wears out rapidly, and it also takes too long to rewind when switching from recording to playback mode, and the tape wears out during repeat playback, causing audio quality to deteriorate. There was a drawback.

明の一実施例を図面にもとづいて説明する。 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.

る。 The drawing is a configuration diagram of 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. Reference numeral 3 denotes a solid-state storage device such as a semiconductor memory, which constantly stores the output of the tape recorder 1 inputted via the analog-to-digital converter 2. However, since the capacity is limited, it is rewritten one after another as new information is input one after another, that is, audio signals from a certain moment up to, for example, several tens of seconds are always stored. 4 is a digital-to-analog converter, which converts the signal read from the solid-state storage device 3 into an analog signal. Reference numeral 5 denotes a changeover switch that selects either the output of the digital-to-analog converter 4 or the output of the tape recorder 1 and applies it to the output terminal 6. 7 starts reading.
The end control section controls which part of the recorded content is read out, reproduced, and ended when the solid-state storage device 3 is put into the reading state, and specifies the start and end points of reading. This makes it possible to repeatedly reproduce only the necessary portions. Reference numeral 8 denotes an operating state switching control section which switches the operating modes of the tape recorder 1, solid state storage device 3, changeover switch 5, and read start/end control section 7 as will be described later, as indicated by broken lines.

The tape recorder 1 is put into the operating state by a signal from the operating state switching control section 8, 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 is input to the solid-state storage device 3 via the analog-to-digital converter 2, and is sequentially stored in the form of a digital signal.

The signal stored in is read out, restored to the original signal by the digital-to-analog converter 4, and then outputted to the output terminal 6 via the changeover switch 5.

る。 Here, by specifying the read start and end points using the read start/end control section 7, it becomes possible to reproduce only the necessary portion. Therefore, compared to a device where the repetition period is set constant, for example, even if the necessary part is short, it is possible to omit the playback of unnecessary parts and immediately repeat the playback, and it is also possible to stop and start the tape recorder. This is very convenient in practice, as it allows you to play without noise, which often occurs at times.

While playing a VTR, you can instantly check the previous content if necessary, and you can listen to it over and over again, so you can take notes of what you missed. You can easily and accurately reproduce things that you would like to listen to over and over again. Furthermore, since the start point and end point of the portion that needs to be reproduced can be specified, there is no need to listen to unnecessary portions, which is extremely convenient in practice.
