BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus having a repeat function.

[0002]

2. Description of the Related Art Conventionally, many recording / reproducing apparatuses have a so-called repeat function for repeating a reproduced content during recording / reproducing. In recent years, as shown in Japanese Patent Application Laid-Open No. Sho. A storage device using a storage means including a semiconductor memory has been developed. In such a recording / reproducing apparatus, a recorded voice is converted into a digital signal and the recorded content responding to a predetermined reproduction time is stored in a storage means.For example, in a tape reproducing apparatus, a tape is used for repetition. There is an advantage that no mechanical operation such as reversing the running is required, and no stress is applied to a recording medium such as a tape for such reversal driving.

[0003]

The recording / reproducing apparatus having such a repeat function performs endless recording of the reproduced sound, so that when the capacity of the storage means is not sufficient, the recording / reproducing apparatus performs repeat reproduction from the beginning of the stored data. After all of the storage means have stored, the stored contents are rewritten, and the repeat reproduction is performed by reading from the stored contents of the address immediately after the rewriting.
In other words, the content to be stored is increased, and in the case of repeat reproduction, the content is read from the beginning. For this reason, the repeat reproduction is started from an arbitrary recording start position, independent of the operator's intention to confirm the reproduced sound again. Therefore, for example, in the case of repetition of a phrase in an English conversation or confirmation of a missed word in a lecture, a desired reproduced sound cannot be confirmed until after listening to a considerably long time before that.

As another method of the repeat reproduction, there is a method in which an operator instructs the timing of storing in the storage means with a push button or the like, and based on the instruction, starts the storage and repeats the reproduction of the stored contents. For example, buttons are operated after the start of a new phrase, or button operations are performed after feeling that you missed it, so even if you have a delay memory for storage, it often shifts from the desired timing, so it is preferable Did not.

[0005]

Means for Solving the Problems In consideration of the above points, the present invention considers phrases that are easy to hear in phrases and lectures of a conversation learning device, so-called non-recording times such as blank time for repeated learning and breathing. The output of the reproduction amplifier is stored in the storage unit based on the output of the non-recording detection unit that detects no recording from the output of the reproduction amplifier that reproduces the recorded voice. When the output of the regenerative amplifier is amplified by the amplifier, a repeat unit is provided for reading out from the storage unit upon reception of the repeat signal and inputting the signal to the amplifier.

[0006]

As a result, the repeat reproduction is performed based on the non-recorded portion.

FIG. 1 is a block diagram of a recording / reproducing apparatus showing an embodiment of the present invention. Reference numeral 1 denotes a reproducing amplifier for reproducing a recorded voice from a recording medium 11 such as a tape or a disk via a head 12. Numeral 2 denotes a non-recording detecting means for detecting non-recording from the output of the reproducing amplifier 1, a comparator 21 for judging whether the output level of the reproducing amplifier 1 is equal to or higher than a predetermined value, and a constant of the comparator when the recording / reproducing apparatus is in the reproducing mode. A timer means 22 for measuring whether the output that is equal to or less than the value has continued for a fixed time (for example, 0.5 seconds or more), and an output from the regenerative amplifier 1 having a constant value after the clock means has counted a certain time. It comprises a timing means for outputting a signal if it exceeds the limit, and a gate 23 for generating an end signal for a silent portion consisting of an AND gate having an inverted output of the comparator as an input.

Reference numeral 3 denotes storage means for storing the output of the reproduction amplifier 1 based on the output of the no-recording detection means 2, and a processor 33 for controlling the semiconductor memories 31, 32 and the addresses, storage / readout, etc. of the semiconductor memories 31, 32. And regenerative amplifier 1
A / D that delays the output signal of analog and converts it to analog / digital
34, and a D / A 35 for converting the contents of the semiconductor memory into a digital-to-analog signal and outputting the converted signal. Reference numeral 4 denotes an amplifier for selectively inputting and amplifying the output of the reproduction amplifier 1 and the output of the storage means 3, and the output is connected to a speaker 41. Numeral 5 is a repeat means for receiving a repeat signal when the output of the regenerative amplifier 1 is amplified by the amplifier 4, reading from the storage means 3 and inputting the output of the storage means 3 to the amplifier 4.
The key scan of the reproduction switch 61, the repeat switch 62, etc., and the switching control of the changeover switch 63 are performed, and the motor 64 for driving the recording medium is also controlled as necessary. Become.

In such a configuration, for example, the recording medium 1
The operation will be described by taking as an example a case where three phrases A, B, and C are recorded with a non-recording part interposed therebetween. During reproduction, a reproduction switch 61 is operated, power is supplied to each circuit part, a motor 64 is driven, and a changeover switch 63 is operated.
Is set so that the output of the regenerative amplifier 1 is guided to the amplifier 4. At this time, the processor 33 stores the semiconductor memories 31, 3
2 is set to the storage mode. When the reproduction of the storage medium 11 is started, the first non-recording section 2 detects the first non-recording section, and outputs from the gate 23 of the non-recording detecting section 2 in response to the first voice of the phrase A. Processor 33
Designates the start address of the semiconductor memory 31 and A / D3
4 is instructed to start conversion. Then, the address of the semiconductor memory 31 is sequentially updated in synchronization with the conversion timing of the A / D. Thus, the phrase A is stored in the semiconductor memory 31. At this time, the sound of the phrase A is reproduced by the amplifier 4, but the timing of the analog-to-digital conversion is delayed by the operation time of the comparator 21, the gate 23, the repeat means 5, and the processor 33 of the no-recording detecting means 2. However, since this delay time is a substantially constant time that can be scheduled in advance, a delay corresponding to the delay time is A /
The first portion of the phrase A is not lost in the storage in the semiconductor memory 31 because it is provided before D34.

As the recording medium 11 is reproduced, the second unrecorded portion is reproduced.
3 stores the phrase B in the semiconductor memory 32 in the same manner. In this case, when receiving the output of the timekeeping means 22 of the no-recording detecting means 2, the processor 33 merely needs to change the address designation to the head address of the semiconductor memory 32 for storage.
The next phrase C is stored in the semiconductor memory 31.

As described above, the phrases are alternately stored in the two semiconductor memories 31 and 32 based on the unrecorded portion.
If the repeat switch 62 is operated in the middle, the repeat means 5 switches the changeover switch 63 to the storage means 3 side, switches the semiconductor memories 31 and 32 from the storage mode to the read mode, and switches the semiconductor memory which is not currently addressed. Address the memory and specify the D / A 35 conversion. D
By sequentially updating the address in synchronization with the conversion of / A35, the contents of the semiconductor memory are reproduced as audio,
Is output via. For example, when the repeat switch 62 is operated after the predetermined time of the second non-recording portion has elapsed or during the reproduction of the second phrase B, and the repeat means 5 receives the repeat signal from the repeat switch 62, the current address becomes the semiconductor memory 32. Therefore, the reading is started from the head address of the semiconductor memory 31, and the phrase A is reproduced.

It is preferable that one of the following two processes be performed for reproduction after the end of repeat reproduction.

When the reproduction operation is stopped in the repeat operation and the reproduction of the recording medium which has been interrupted again when the repeat reproduction is completed is continued, the next phrase often starts in the middle. In this case, the reproduction up to the point where the operation was interrupted may be repeated.
There are two methods. One is that the storage of the semiconductor memory is performed in units of phrases. However, one semiconductor memory is repeatedly reproduced and then the other semiconductor memory is also reproduced. The other is to provide two sets of addresses of the processor 33 so as to correspond to the semiconductor memories 31 and 32, respectively, and to record the phrase B in the semiconductor memory 32 as long as the storage capacity of the semiconductor memory 31 remains. However, it is memorized twice. In repeat reproduction, all the stored contents are reproduced and output, and then reproduction of the recording medium is restarted. For example, if the repeat switch is operated during the reproduction of the phrase B, the contents of the phrase B until the repeat switch is played are recorded in both of the two semiconductor memories 31 and 32. After the recording has been completed, the recording medium is reproduced, so that all the contents can be heard.

Since the repeat means 5 controls the motor 64 in the reproduction processing, the storage is continued until the non-recording signal is output from the timer means 22 of the non-recording detection means 2 even after the repeat reproduction signal is received. Semiconductor memories 31, 32
It is also effective to stop the reproduction of the recording medium after all the phrases are stored. In this case, the contents of any semiconductor memory can be read out by operating the repeat switch 62, which is effective for learning English conversation, for example. Specifically, when the repeat switch 62 is operated in the middle of the phrase B, the phrase A is repeatedly played back, but the recording medium 11 is in the third unrecorded portion (after the phrase B).
Will be stopped. If the subsequent operation of the repeat switch 62 is short, the repeat means 5 repeat-plays the phrase A as many times as long as the repeat signal is short. When the repeat play is over, the repeat means 5 maintains the stop state. When the repeat switch 62 is operated for a long time (for example, 0.8
(Seconds or more), the repeat means 5 operates the processor 33
And the phrase B stored later is reproduced. Therefore, an opportunity to repeat the same phrase any number of times is obtained. When it is desired to proceed to the next phrase, the reproduction switch 61 may be operated again.

[0015]

[Effect of the Invention] As described above, according to the present invention, since the storage in the storage means is based on the unrecorded portion, the repeat playback is repeated from a certain beginning of the sentence, and the phrase for language learning is reproduced. It is possible to easily confirm the missed points such as repetitions and lectures.
