Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the functionality of a group learning device.

BACKGROUND ART Group learning devices, such as language practice devices and music practice devices, have been known in the past, in which a plurality of study tables for students are provided for one adjustment console for the teacher. In conventional group learning devices of this type, for example, language practice devices for learning English conversation, a teaching material tape is played back using a tape recorder installed in the adjustment console, and the played teaching material signal is transmitted to a tape recorder installed in each learning desk. I'm trying to record it. This allows students to repeatedly practice English conversation while playing back recorded teaching material signals.

When recording the teaching material signal, all tape recorders of each study desk are operated by remote control on the adjustment console side. That is, first, all tape recorders are set to rewind mode, the tape is rewound to the top of the tape, and then stopped, and then set to recording mode, when the tape has traveled the length of the leader tape, the tape recorder on the adjustment console side is set as playback mode, and the played teaching material signal is recorded. Conventionally, these operations, such as rewinding, stopping, recording, and playback, were performed by pressing the corresponding operation buttons in sequence. For this reason, it is difficult to confirm, for example, whether rewinding has been completed on all tape recorders, and in reality, the user waits a suitable time after rewinding and then presses the stop button. As described above, in the past, when recording educational material signals, timing of operations for remotely controlling a large number of tape recorders was difficult, and as a result, erroneous operations were likely to occur, resulting in recording failures. In addition, while preparing the recording, the teacher is busy with the preparation work and the tape recorder for the students cannot be used, so there is almost no learning to be done, and this results in wasted time in the class. , impairing learning efficiency. Recently, such a device has been proposed that copies teaching material signals in a short time while increasing the speed of the tape, and in this case, it is necessary to copy teaching material signals more efficiently and reliably.

The present invention has been made in view of the above problems, and embodiments of the present invention will be described below with reference to the drawings.

In the drawing, an operation button 1 for instructing automatic recording, a tape recorder 3 for reproducing teaching materials, a system control circuit 2, and an AND gate 4 are provided on the adjustment console side. Further, the n study desks are provided with tape recorders 5 ₁ to 5 _o for recording and reproducing teaching material signals.

When a teaching material signal is to be recorded, when the operation button 1 is pressed, an automatic recording instruction signal S _R is applied from the system control circuit 2 to the tape recorders 5 ₁ to 5 _o , respectively. This instruction signal S _R includes information for sequentially performing the above-described series of operations for recording the educational material signal, such as rewinding, stopping, recording, and reproducing operations at predetermined timings. This instruction signal S
_R causes the tape recorders 5 ₁ to 5 _o to first go into rewind mode, and all tapes are rewound. Each of the tape recorders ₅₁ to _5o is provided with a means for detecting the rotation of the reel shaft, and when the tape is rewound to the tape top and the reel shaft stops, the rotation detecting means outputs a tape top detection signal. can get. The detection signals S _D1 to S obtained from the rotation detection means of each tape recorder 5 ₁ to 5 _o
Do is added to AND gate 4. Therefore, an output signal is obtained from the AND gate 4 when the tapes of all the tape recorders ₅₁ to _5o are rewound to the tape top. Based on this output signal, the system control circuit 2 temporarily stops the tape in each tape recorder, and then sends an instruction signal S _R to set the tape recorder to recording mode. As a result, the tape in each tape recorder stops once and then starts running. Next, when each tape has run the length of the leader tape, for example, several seconds after the above-mentioned stop,
A reproduction command signal S _p is applied from the system control circuit 2 to the tape recorder 3 . As a result, the tape recorder 3 enters the reproduction mode, and the reproduced teaching material signal _ST is applied to the tape recorders 5 ₁ to 5 _o and recorded on each tape. Incidentally, the reproduced teaching material signal S _T is monitored by a headphone (not shown) provided on the adjustment console. When the operation button 1 is pressed again when the reproduction of the teaching material signal S _T is completed in the tape recorder 3, the system control circuit 2 instructs each tape recorder 5 ₁ to 5 _o to cancel recording. As a result, each tape recorder is brought to a halt state, and the recording of the educational material signal is completed.
When performing the above-mentioned high-speed copy, the tape must be stopped once and entered into recording mode, and then
The tape recorder 3 may be set to playback mode after ~0.7 seconds.

As described above, according to the group learning device according to the present invention, when recording a teaching material signal with the tape recorder of the study desk, a series of operations can be automatically performed by simply operating one operation button on the adjustment console side. Therefore, erroneous operations can be eliminated, and teaching material signals can be reliably recorded on the tapes of all tape recorders. Furthermore, since both the teacher and the students have free time during the time from when the operation button 1 is pressed until the end of the recording, it is possible to use this time to conduct other classes. Therefore, learning can proceed more efficiently and the learning effect can be enhanced.
