Become.

[Problems to be Solved by the Invention] However, even if an attempt is made to learn English conversation using such a card player, the audio recorded on the card 5 will only be played back unilaterally by the above-described playback operation. However, there is a lack of interactivity, and only two voices can be recorded.
Since it was short, about 7 seconds, there was a problem that the learning mode had no development potential. For example, just playing one card can only be used to check pronunciation.

Of course, if a large number of cards are played one after another, it is possible to create a dialogue state using the playback audio, for example, but in such a case, the user is distracted by the card playback operation and cannot concentrate on the playback audio, making it difficult to learn at all. Therefore, it has the disadvantage that it is not suitable as a learning device.

Means for Solving Problem U] The present invention has been made in view of these problems, and includes a card reproducing circuit equipped with a reproducing head means corresponding to two or more recording tracks formed on the card. In addition to providing
A storage circuit unit capable of storing predetermined audio data among the audio data of each recording track read by the playback head means is provided, so that when a card on which two or more recording tracks are formed is inserted, ,
The audio data read from one designated recording track is played back and output as is from the speaker unit, etc. At the same time, the audio data read from other recording tracks is input to the storage circuit unit and temporarily stored, and the audio data is output at the desired time. It is configured so that it can be read out and output as reproduced audio.

[Function] By using the card player of the present invention, two or more tracks can be formed on a card to record questions and answers in English conversation, for example.

It becomes possible to record relatively long audio by dividing it into tracks.

[Embodiment] FIG. 1 shows the appearance of an embodiment of a card player of the present invention, and the same reference numerals as in FIG. 5 indicate the same parts. In this embodiment, an example will be exemplified in which the contents of a card 5 having two tracks 6a and 6b formed on the magnetic recording section 6 can be reproduced.

A track selection switch 17 is used by the user to select which of the tracks 6a and 6b will be directly reproduced, as will be described later. Reference numeral 18 is a memory playback button, and as will be described later, the playback audio signal of the track that was not directly played back and output is stored in the storage circuit section, and the user operates this button when the user wants to listen to the stored sound. It is something to do.

In order to read the magnetic data of two tracks, the reproducing head 10 provided near the boundary between the insertion groove 1 and the running groove 2 has two units of head elements 1 as shown in FIG. 2, for example.
0a and 10b are provided. Further, as a card detection mechanism and a card running mechanism, mechanisms similar to those shown in FIG. 6 are provided. Note that the playback head 10

Note that 8, 11, and 16 indicate a detection switch, a capstan, and a capstan motor, respectively, which are similar to those shown in FIG. 6 above.

25 is an A/D conversion circuit that converts the reproduced signal obtained from the head element 10a or 10b into a digital signal; 26 is a solid-state memory that stores the reproduced signal converted into digital data; and 27 is a solid-state memory that stores the reproduced signal that has been converted into digital data. Reference numeral 628 is a system control circuit section (hereinafter referred to as a control section), which is a D/A conversion circuit that converts the output data into an analog signal. Selection information from the switch 17 and a playback operation signal from the memory playback button 18 are input as control information.

The control section 28 is also equipped with a clock generation means and an address counter used for storage/read processing of reproduced data, and an A/D conversion circuit 25. A sampling clock is supplied to each of the D/A conversion circuits 27, and a write/read address signal is supplied to the solid-state memory 26 along with a control signal and a clock for writing/reading. It controls the A/D conversion and storage operation of the reproduced signal, and the reading and D/A conversion of data stored in the solid-state memory 26.

Note that S, , S2. S indicates a switching circuit whose contacts are switched and controlled by the control section 28.

In the card player of this embodiment, the control unit 28 performs system control and executes card playback operations based on the detection of insertion of the card 5 by the detection switch 8 and the operation of the track selection switch 17 and the memory playback button 18. Its operation will be explained with reference to the time chart of FIG.

First, it is assumed that the track selection switch 17 is set so that the track 6a is directly played back when the card 5 is inserted (at the time of to).

Corresponding to the track selection by the track selection switch 17, the control section 28 connects the switching circuit S1 to the a contact and the switching circuit S2 to the b contact.

When the card 5 is inserted from the insertion groove 1 at time t1, a detection signal is output from the detection switch 8 to enter the playback mode, as explained in FIG. is driven, and the card 5 starts running in the running groove 2. Further, the switching circuit s3 is connected to the C contact.

Therefore, from time t5, card 5 finishes running at t2.
Up to this point, the reproduced signal from the track 6a read by the head element 10a is amplified as it is via the switching circuits S, . . . S3, and is supplied to the speaker device 24 and output as audio.

Meanwhile, during this time, the reproduction signal from the track 6b read simultaneously from the head element 10b is supplied to the A/D conversion circuit 25 via the switching circuit S2, and is converted into a digital signal based on the control of the control section 28. It is stored in memory 26.

When the user presses the memory playback button 18 at time t3, for example, after listening to the reproduced audio of the track 6a, the memory playback mode is entered, and the control unit 28 connects the switching circuit S3 to the d contact, and Controls reading of the solid-state memory 26. That is, the audio data of the track 6b stored in the solid-state memory 26 is read out, converted into an analog signal, and supplied to the speaker device 24 via the switching circuit S3 for reproduction and output (ts
Note that this memory playback operation can be repeated any number of times until a new card is inserted and the playback operation is performed.

In this way, since the data of two tracks can be read simultaneously and played back sequentially, each track 6a, 6 of the card 5
If, for example, questions and answers in an English conversation are recorded in B, the user can first insert the card 5 into the card player, listen to the questions, and then simply operate the memory playback button 18 at the desired time. , you can listen to the answers, making it suitable for learning, etc.

Furthermore, in this embodiment, by switching the track selection switch 17, it is possible to switch between a track whose contents are directly reproduced and a track whose contents are temporarily stored in the solid-state memory 26.

For example, at time t5, switch the track selection switch 17,
When track 6b is selected, switching circuit S1. St is connected to the b contact and the a contact, respectively. Therefore, at the time from t6 to t7 when the card 5 is inserted and the regeneration run is performed,
The reproduced audio of track 6b is output from the speaker device 24, and the reproduced audio of track 6a is output from the solid-state memory 24.
6 is stored. Then, at time t8, when the memory playback button 18 is pressed and the memory playback mode is entered, track 6
The reproduced audio of a is read from the solid-state memory 26 and output from the speaker device 23.

In this way, in this embodiment, the data on one track can be directly reproduced, and the data on the other track can be temporarily stored in the solid-state memory 26 and read out at a desired time. Questions and answers can be recorded on the screen to provide interactivity, and different usage methods can be considered by switching the track to be played first.

Furthermore, relatively long sounds that cannot be recorded on one track can be recorded on two tracks, and if used as a learning device, for example, various usage modes can be realized. Although the memory playback mode is started by operating the memory playback button 18, for example, after the playback of 5 cards 5 is completed, a predetermined time is counted and the memory playback is automatically performed. good.

In this embodiment, the card player is compatible with two tracks of cards, but a case with three or more tracks is also conceivable. In that case, in addition to matching the number of head elements, the required number (number of tracks - 1) of memory circuit sections consisting of an A/D conversion circuit, solid-state memory, and D/A conversion circuit is provided, and tracks other than the tracks to be directly reproduced are It is only necessary to configure the device so that it can store playback data and read out each stored content at a desired time.

Furthermore, the playback data of tracks that are directly played back can also be stored in the solid-state memory, making it possible to repeatedly play back the data of all tracks any number of times.

[Effects of the Invention] As explained above, the card player of the present invention reads the data of each track corresponding to a plurality of tracks on the card, directly reproduces and outputs one track, and outputs data for other tracks. Since the playback data can be temporarily stored in a memory means and then played back and output at a desired time, it is possible to add interactivity to the recorded contents on the card and extend the recording time, etc. as a software. This has the effect of increasing the variety of cards, expanding the scope of application of the cards and card players, and improving their usefulness. In particular, when used as a learning device, learning modes can be expanded with the diversity of software, and learning effects and efficiency can be improved.
