Indicates a learning card with a magnetic tape, which is formed by a paper card 2 having a size of width 187 x height 115 x thickness 0.45 mm, on the surface of which, for example, a picture of an "apple" 3 and the character 4 of "apple" are printed. Further, under the card 2, a magnetic tape 5 used in an open reel type tape recorder is stuck in parallel with the long side, and the sound of "Apple" is recorded in English on this tape 5. There is.

FIG. 9 shows a player of the learning card 1 with the magnetic tape, which has a structure similar to that of a general tape recorder, except that a card guide groove 7 is used instead of the reel shaft and the tape guide pin. Are formed. Then, as shown in the drawing, when the lower left end of the card 1 is inserted into the groove 7, the card 1 is guided to the groove 7 by the capstan and the pinch roller (neither is shown) and is fed leftward, At this time, a reproducing head (not shown) contacts the tape 5, and the sound of "Apple" recorded on the tape 5 is reproduced from the speaker 8.

The feeding speed of the card 1 is 2.4 cm.
/ Sec, so the maximum play time for one card is 6.2 seconds. Therefore, according to the learning card 1 with the magnetic tape, the English words can be learned at the same time visually and aurally, and the short sentences can be reproduced, which is suitable for the English education of children. Alternatively, depending on the contents of the card 1, it is possible to learn kanji, vehicles, insects, animals, plants, greetings, and the like. In this way, the learning card with magnetic tape 1
Can be conveniently used for children or toddlers to learn.

[0005]

However, the learning card 1 with the magnetic tape is not flexible in the card 2 and the improvement of the head touch of the tape 5 is desired, and the feeding speed of the card 1 is slow. Was limited. Also, since the reproduction time is limited to 6.2 seconds at the maximum, and only information for a short time can be reproduced, it is difficult to handle stories and songs, and it cannot be used like ordinary picture books and records. For example, there is a method of dividing a story or song into several cards, but it is inconvenient to handle. The present invention is
It is intended to solve the above problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the card or booklet reproducing system of the present invention will be described below with reference to FIGS.
That is, in FIG. 2, reference numeral 10 denotes a card used in this example, which has a rectangular shape as a whole and is formed of, for example, a paper card 12 having the same size as the learning card 1 with a magnetic tape. Then, on the surface of this card 10, in the example of FIG. 2, a picture 13 of "apple" and "apple"
And the characters 14 are formed by printing. In addition, below the card 10, three sets of barcodes 15A to 15C are provided.
However, it is formed by printing along the long side of the card 10, that is, the reading direction of the barcodes 15A to 15C is the long side direction of the card 10.

In this case, the bar codes 15A and 15B are
It shows the track number and elapsed time (or index number) of the compact disc, that is, the track number and elapsed time (or index number) of the recording position where the audio corresponding to the contents of the card 10 is recorded.
Is a bar code. Also, barcode 15
C is auxiliary control data, bar code 1 in this example
The number of minutes and seconds from the start point of the sound of the track number and the elapsed time (or index number) specified by 5A and 15B is reproduced, that is, the data indicating the reproduction time length is bar-coded. is there.

Further, on the back surface of the card 10, as shown in FIG. 3, an example sentence or an explanation sentence 16 corresponding to the contents of the card 10 is printed. And such a card 10
Is made for each English word. Also, the card 10
A compact disc used in combination with, for example, has the track number "1" at the address of the track number "1" as shown in FIG. 1 or the track number "1" as shown in FIG. Elapsed time "t1" (however,
"T1" is expressed in the form of XX minutes and XX seconds), and the voice of "Apple" is recorded in English corresponding to the contents of the card 10 of FIG. Note that FIG. 1 and FIG.
In, the time T _{101 to} T ₉₉₁₀ indicates the length of each voice (this is not recorded on the compact disc), and the bar code 15C is a bar code of this time. Bar codes 15A and 15B are bar codes of the track numbers and elapsed times (or index numbers) shown in FIGS. 1 and 10.

Further, FIG. 4 shows the appearance of a bar code reader for reading the bar code of the card 10. A card guide groove 17 is formed on the upper surface of the bar code reader so as to extend in the left-right direction. 10 is guided in this groove 17 so that it can travel from right to left in the figure. However, this bar code reader does not have a drive mechanism for feeding the card 10, and the card 10 is manually fed along the groove 17.

FIG. 5 shows a bar code reading circuit of the bar code reader device. That is, reference numeral 21 denotes a photo sensor (bar code reader), which is provided on the wall surface of the groove 17 facing the card 10 so that the card 10 can be inserted into the groove 17.
Bar code 15A-1 when sent by being guided to
5C is read sequentially. Then, the read output of the sensor 21 is supplied to the decoder 22, decoded, and then supplied to the controller 23. The controller 23 is composed of, for example, a 4-bit microcomputer, and converts the outputs of the decoder 22 corresponding to the barcodes 15A and 15B into the format of the remote control signal of the compact disc player, which will be described later. At the time of output corresponding to 15C, the reproduction time length (T ₁₀₁ or the like) indicated by the bar code 15C is measured, and after the lapse of the time length, a remote control signal or the like for placing the compact disc player in a pause state is formed.

The controller 23 has the same address of the compact disc (recording location of the same track number and the same elapsed time (or index number)).
Repeat switch RPT for repeat playback
A stop switch STP for stopping the repeat reproduction, a down switch DWN for decreasing the reproduction volume by one step each time the reproduction volume is pressed, and an up switch UP for increasing the reproduction volume are connected, and the outputs of these switches are also converted into the remote control signal format. To be done. The switch RPT
Each of DWN to DWN is a non-lock type push switch and is provided on the surface of the barcode reader device.

Then, the remote control signal from the controller 23 is supplied to the modulation circuit 24 to be a PWM pulse,
This pulse is transmitted to the infrared LED through the drive amplifier 25.
26. The LED 26 is provided on the surface of the bar code reader device, and infrared light from the LED 26 is transmitted to the compact disc player. And FIG. 6 shows a player which is used in combination with a bar code reader device to reproduce the compact disc described above. This player is a general compact disc player that is commercially available. In this example, when the track number and the elapsed time (or index number) of the compact disc are designated by the infrared remote control signal, the playback is performed from the designated position. It is of a type that can be operated by various remote controls, such as the start of a remote control. Although not shown, the reproduction signal of this compact disc player is supplied to the speaker through the audio amplifier.

According to this structure, when the card 10 is used (during learning), the compact disc described in FIG.
0 may be manually sent along the groove 17 of the barcode reader device. That is, by doing so, the bar codes 15A to 15C are sequentially read by the sensor 21, and the controller 2 detects the bar codes 15A and 15B from the read outputs.
At 3, the remote control signal indicating the track number and the elapsed time (or index number) is formed, and the command signal for setting the compact disc player in the reproduction mode is also formed, and these are transmitted to the compact disc player by the LED 26. At this time, the reproduction time length is extracted from the read output of the bar code 15C, and the controller 23 starts measuring the reproduction time length.

Now, assuming that the card 10 is that shown in FIG. 2, the elapsed time "t1" of the track number "1" of the compact disk is changed by the infrared light from the LED 26.
The reproduction of the audio signal is started from the position (or the index number "1"), so that the sound of "Apple" is reproduced from the speaker (not shown). Then, when the sound of "Apple" ends, the time length T ₁₀₁ elapses, so that the controller 23 forms a remote control signal for designating a pause, and the pause signal is transmitted to the compact disc player by the LED 26. The player is in a paused state, and no sound is reproduced thereafter.

In this case, the repeat switch RPT
When is pressed, a remote control signal indicating this repeat reproduction is output from the controller 23 and transmitted to the compact disc player by the LED 26 so that the player is set to the repeat reproduction mode and the pause signal is generated even after the time length T ₁₀₁ has elapsed. Is not formed. Therefore, the time length T ₁₀₁
After the passage of, the elapsed time of the track number "1""t
The reproduction is performed from the position of "1" (or the index number "1") and the sound of "Apple" is reproduced. Then, this is repeated until the stop switch STP is pressed.

The same operation is performed when another card 10 is placed on the bar code reader, and the card 10 is read from the address of the track number and the elapsed time index number indicated by the bar code 15A, 15B. The audio corresponding to 10 is reproduced. Thus, according to this example, when the card 10 is sent to the groove 17 of the bar code reader device, the sound corresponding to the card 10 is reproduced from the compact disc, so that the sound quality of the reproduced sound is very good. Not only can music and sound effects be obtained with sufficient sound quality.

The playback time for one card 10 is determined by the capacity of the compact disc, which is a maximum of 74.
Since it is a little more powerful, it can be played for a sufficiently long time and can handle stories and music. Moreover, it is easy to handle and easy for children. In addition, card 10
Need only print the bar code 15A to 15C at the same time as the picture 13 and the character 14 on the blank card 12,
The card 10 can be very low cost. In addition, the capacity of the compact disk is equivalent to 700 or more (= 74 minutes / 6.2 seconds) of the learning card with magnetic tape 1 (= 74 minutes / 6.2 seconds), and one compact disk can be easily duplicated. The cost corresponding to the card 10 is low.

Further, the bar code reader is also inexpensive since it only needs the reading circuit shown in FIG. 5 and does not require a drive mechanism for the card 10. Further, a compact disc player may be a general one, and a dedicated machine is not necessary. Also, since it is possible to record more than 74 minutes of voice on one compact disc, for example, in the case of English conversation, the compact disc holds many English conversations, but the card 10 is divided into several stages, and the first stage card 10 is divided. If the master is mastered, the second-stage card 10 is additionally purchased, and if the master is mastered, the next-stage card 10 is additionally purchased.

Further, the card 10 can be considered as a remote controller of a compact disc player, and the card 1
If the karaoke lyrics and the bar codes 15A to 15C are printed one by one for each 0, it is easy to find the beginning of the karaoke, and at the same time, it is very convenient without the trouble of searching for the lyrics card. It is also convenient for playing music by movement. Alternatively, it can be used for games such as Hyakunin Isshu, Carta, and Intro. In addition, you can cut randomly like hundreds of people's islets or cards, and you can intuitively sort things you remember and those that you do not. By the way, a part of the compact disc player has an accessory connector through which a signal of track number and elapsed time (or index number) can be inputted, and track number and elapsed time of the address currently being reproduced. There is a player that can output a signal (or index number).

FIG. 7 shows an example of a bar code reader used in combination with a compact disc player having such an accessory connector. That is, the controller 23 is connected to the plug 28 through the interface 27, and the plug 28 is connected to the accessory connector of the compact disc player.

When the card 10 is sent to the groove 17, the bar codes 15A and 15B are read, a signal indicating the track number and the elapsed time (or index number) is formed in the microcomputer 23, and the player is set to the reproduction mode. Command signals are formed, these signals are supplied from the plug 28 to the player through the interface 27, and the corresponding audio signals are reproduced from the compact disc of the player. At the time of this reproduction, a signal indicating the currently reproduced track number and the elapsed time or the index number is also extracted from the compact disc, and this signal is supplied from the plug 28 to the controller 23 through the interface 27 to the card 23. 10 is compared with the track number and the elapsed time (or the index number), and when both are equal, the reproduction is continued as it is, but when they do not match (this is the track number and the elapsed time indicated by the card 10 ( (Or when the playback of the voice of the index number) is finished), if the switch RPT is pressed, repeat playback is performed, and if the switch STP is pressed, the pause state is set and the next card 10 is played. It will be in a standby state.

In the case of this connector type, the response of the compact disc player to the operation of the card 10 can be speeded up. In the above description, the present invention is applied to a card, but it may be a booklet such as a picture book or a musical score. In that case, the sensor 21 is detached from the barcode reader device and the barcode 15A.
-15C is read, which is more effective as a voiced picture book or a musical score with a performance, and can be used in a wider range.

Further, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.

[0025]

According to the disc reproducing apparatus with remote control of the present invention, high sound quality can be obtained, and the reproducing time and the reproducing start position can be arbitrarily set. Further, according to the present invention, the bar code address information which is the print information is read by the bar code reader and the reproduction is started from the position where the address signal of the disc corresponding to this address information is recorded, so that the operation is simple. is there. Further, the repeat reproduction mode can be easily set by operating the repeat switch provided on the bar code reader.
