Description

[Detailed Description of the Invention] The present invention relates to a tape recorder for language practice that can be set to a so-called practice state in which teaching material tracks are played back and student tracks are recorded.

A language practice tape recorder has a practice state mode in addition to the playback mode.

In a general 4-track, 2-channel cassette tape recorder, the two channels can be used for simultaneous recording or simultaneous playback, which are called a recording mode and a playback mode, respectively.

In addition to these modes, the language practice tape recorder has a practice state mode. In Fig. 1, while playing the teaching material tracks 1b and 1c of the magnetic tape 1, the learner's practice audio is recorded on the practice tracks 1a and 1b. It is for recording.

In language practice, the learner listens to the teaching material, records it as the learner pronounces it, then rewinds the tape recorder and compares the sound of the teaching material with the learner's pronunciation.In the next sentence, the learner listens to the teaching material again. A repeated operation of recording is performed.

Conventionally, in the practice state of this type of tape recorder, there have been two methods for changing from the playback state to the practice state.

(1) Record a specific signal on the student track in the practice state,
A method that continuously monitors the presence or absence of the signal during a temporary playback operation and switches from the temporary playback state to the practice state without the signal.

(ii) After cueing and rewinding without any detection means,
A method that enters a playback state and maintains that state, and requires an operation such as pressing the practice mode switch to return to the practice state.

However, the method (1) described above requires means for generating a specific signal, and means for extracting the specific signal component from the voice output during reproduction.

Furthermore, the specific signal naturally falls within the audible range due to the recording and playback frequency characteristics of the tape recorder, and there is a risk of inhibiting learning, so special care must be taken to remove it from the audio output, resulting in a complex structure. I can't help it.

Further, the method (11) described above requires frequent operations and is inconvenient in handling.

In view of the above method, the present invention is designed to automatically return to the practice state at the beginning of the next sentence after rewinding the playback.

Examples thereof will be described below.

In FIG. 2, 1 is a magnetic tape, 2 is a magnetic head, and 3 is a reproduction amplification circuit.

Reference numeral 4 denotes a terminal where playback output is generated, to which headphones or the like are connected.

Reference numeral 5 designates a circuit that generates a pulse indicating the start of the teaching material audio, 6 a binary counter, 7 a register for setting the practice mode, 8 a playback register, and 9 a rewind register.

10 is a rewind counting circuit; 11 is a switch for cueing and rewinding; 12 is a switch for setting practice mode;
13 is an OR circuit.

Next, the operation will be explained.

Now, when the switch 12 is pressed, the practice mode register 7 is set, the practice state is set using an appropriate means (not shown), and tape running is started.

Listen to the first teaching material sound such as "tt Iam a boy" and then listen to the next teaching material sound such as "You are a qir".
If the cue rewind switch 11 is pressed before "I" is played, the binary counter 6 is reset, the practice register I is reset, and the rewind register 9 is set, resulting in a rewind state.

Then, the rewind counting circuit 10 is activated.
When the tape has been rewound to the first tape position of "Boy", the playback register 8 is set using an appropriate means (not shown), and both the teaching material track and the student track are in a playback state (referred to as a temporary playback state).

) to run the tape. When the first part of "Iamaboy" is reproduced, the teaching material audio start pulse generating circuit 5 generates one pulse and increments the binary counter 6 by one.

When the playback of "I am a boy" is finished and the first part of the next teaching material "You are a boy" is played back, the teaching material audio begins. The pulse generating circuit 5 generates one pulse, and the binary counter 6 Further air blow.

By the way, since this counter 6 is a binary counter, it can be outputted by the second pulse, setting the practice register 1, resetting the reproduction register 8, and automatically returning the tape to the practice state.

Thereafter, the same operation is repeated, but if the cue rewind switch 11 is not operated in the practice state, no change will occur in the operation even if the binary counter 6 outputs an output.

Although not shown, the binary counter 6 is configured not to operate during a true reproduction state.

As is clear from the above explanation, according to the present invention, simply by operating the cue/rewind switch from the practice state, when the next teaching material sound for repeated listening is played, the practice state is automatically returned to. It is not necessary to operate a practice mode switch every time a student performs a practice mode, and it is possible to provide a device that is less complicated to operate for a learner.
