The present invention relates to an information selective playback device equipped with a disc player that can selectively play back desired portions of recorded program information.

B. Summary of the Invention The present invention is capable of selectively reproducing a desired portion of recorded program information from a disc, which is an information recording medium on which program information is recorded, such as a digital audio disc. In an information selective playback device equipped with a disc player, the disc player is provided with a barcode reading section, and the selective playback operation of the program information recorded on the disc by the disc player reads the written content corresponding to the program information recorded on the disc. The control is performed according to the successive outputs of the barcode reader with respect to the barcode placed on the text containing the text. By causing the disc player to stop playing the program information recorded on the disc when the playback is finished, the disc player can This makes it possible to select and obtain only the desired playback program information.

C. Conventional Technology A digital audio disk (hereinafter referred to as DAD) is used, in which an audio signal is digitized and recorded as program information on a rotating disk-shaped recording medium, and a spiral recording track is formed. A DAD system in which an audio signal, which is program information recorded on a DAD, is played back by a disc player has been proposed as an audio signal playback system that can obtain high-quality playback audio signals.

Such a DAD records, for example, two channels of program information, which are left and right signals forming a stereo music signal, and a disc player that reproduces the program information receives two channels of program information from the DAD, that is, The left and right signals that form a stereo music signal are
It is assumed that they can be separated individually and obtained simultaneously.

Furthermore, in a DAD, for example, the program information of two channels recorded therein is in the form of a collection of a plurality of segmented program information, each corresponding to each piece of music, etc., and is accompanied by address data. It is said that This address data is, for example, data usually called a track number (hereinafter referred to as TNO), which indicates the recording arrangement order from the reproduction start end of each section program information.
Indicates the order of subdivisions within one division program information,
Usually, data called index (hereinafter, INDE
X), and time data (hereinafter referred to as T.A.

), etc.).

In the DAD, the innermost circumferential side of the spiral recording track is normally set as the playback start point, and the outermost circumferential side is set as the playback end. Therefore, when normal playback is performed by a disk player, the center of the disk is The read head of the disc player must be moved from the inner side to the outer side. When playing program information from the DAD in this way,
Since address data as described above is recorded along with each segment program information, the read head of the disc player can be directed to a desired recording position on the disc, for example, for a specific segment program, using the playback address data. This makes it possible to selectively reproduce specific section program information and subsequent section program information by moving the information to the recorded position, and moreover, to move the read head to the desired recording position on the disk very quickly. It becomes something that can be done.

By taking advantage of the characteristics of such a DAD system, for example, a training DAD is prepared in which program information corresponding to the contents of a foreign language training text containing a foreign language and its translations is recorded, so that learners can , the content of the text,
It is conceivable to configure an educational device that allows learning to be performed by using a disc player to reproduce program information recorded on a training DAD. In the teaching DAD used in such educational devices, the content of the text is, for example, the entire plurality of sentences in each item constituting the text is classified program information, and each of the plurality of sentences in each item is classified. TNO, which is recorded as a subdivision within program information, and when recorded, changes sequentially for each of multiple sentences in each item,
INDEX that changes sequentially for each of multiple sentences within one item, and INDEX that changes sequentially across multiple sentences within one item <T,
It is assumed that address data including A is attached.

Therefore, when playing back program information corresponding to the content of the text from the training DAD using a disc player, the playback address data is used to play back from the desired item.

It is possible to reproduce from a desired one of a plurality of sentences in a specific item, or from a desired position in a plurality of sentences in a specific item.

D. Problems to be Solved by the Invention However, in an educational device using a disc player as described above, address data recorded in the training DAD is used to create program information recorded in the training DAD. When performing selective playback from a specific location, the TNO and IND corresponding to that specific location are
Input address data such as EX or T, A, etc.
It is necessary to operate data input keys provided on the disc player. Therefore, when learning the content of the text by using a disk player to play back the program information recorded in the training DAD, learners frequently have to operate the data input keys provided on the disk player. This results in the inconvenience of having to take one's eyes off the text, and also leaves the user susceptible to errors in inputting address data.

Furthermore, in conventional disc players, program information recorded on the DAD is
Sectional program information marked with NO.

The beginning of the subsection of the section program information with the selected TNO and INDEX, or the selected TN
Selected T in section program information marked with O
,A, when the playback is performed from the portion specified by They are played back in sequence according to the order in which they are recorded. For this reason, for example, if the text is used as a foreign language teaching text,
As in the case of learning a foreign language, each of the sentences in each item of text is made relatively short, and details of segmented program information corresponding to each such relatively short sentence are retrieved from the disk. If only a segment is desired to be played, a troublesome operation on the disc player is required to quickly stop the playback operation of the disc player when the reproduction of the subdivision of the segment program information is completed. There is this inconvenience.

In view of this, the present invention selectively combines text having content corresponding to program information recorded on a disc with address data and program information recorded on a disc with specific address data. The disc player is equipped with a disc player that can reproduce programs recorded on a disc by the disc player in accordance with the contents of the text by an extremely simple operation that the operator can perform without taking his eyes off the text. It is an object of the present invention to provide an information selection and reproducing device suitable for use as an educational device, which is capable of reproducing only a desired portion of information.

E. Means for Solving the Problems In order to achieve the above-mentioned object, the information selection and playback device according to the present invention is provided with characters or pictures corresponding to program information recorded on a disk together with address data. At the same time, there is a text in which a barcode containing address information representing the address data recorded on the disk is arranged adjacent to these letters or pictures, and a barcode reading unit that reads the barcode arranged in this text. and a disc player. Then, the disc player reproduces a portion of the program information recorded on the disc that includes specific address data according to the address information included in the barcode read by the barcode reading section, and - An information reproducing operation unit is provided which operates to stop reproducing the program information recorded on the disc when the reproducing of the program information portion recorded with data is completed.

F Effect In the information selection and reproducing apparatus according to the present invention configured as described above, the operator can select a specific one of the barcodes arranged on the text, for example, into a pen shape that can be freely handled with one hand. When a reading operation is performed using the barcode reading unit, the information reproduction operation unit of the disc player performs a process to read the information recorded on the disc according to the address information contained in the barcode read from the text in accordance with the output of the barcode reading unit. An operating state is assumed in which a part of the program information corresponding to the characters or pictures that are placed close to the read barcode in the text is reproduced. Then, the specific part of the program information recorded on the disc is played back, and then the information playback operation unit plays back the specific program information part in accordance with the output of the barcode reading unit. When the program is finished, the program automatically stops playing the program information recorded on the disc.

By doing this, the operator can perform extremely simple operations without taking his eyes off the text, for example, by simply scanning a selected one of the barcodes placed on the text with the barcode reader. By operation, it is possible to reproduce only a desired portion of the program information recorded on the disc in accordance with the content of the text.

The specified address data Dx is supplied to the second register 66. Then, the specified address data Dx is supplied from the second register 66 to the comparison operation circuit 64.

At this time, the first register 63 receives TNO and T from the decoding circuit 61 based on the control signal Cd.

Selected playback address data D representing A is supplied,
This signal is sent out in response to the control signal H8 Cn from the central control block 62 and supplied to the comparison calculation circuit 64. The central control block 62 then uses the operation data DO obtained from the comparison operation circuit 64 based on the comparison between the selected playback address data D and the portion of the designated address data Dx containing TNO and start T, A. Based on this, the optical head 43 is brought into a state in which a search operation is performed, as in the case where the above-mentioned TR, L, mode state is taken, and as a result,
Selected playback address data D is specified address data D
TNO and start T at x.

When the search result matches the part containing A and A, the optical head 43 ends the search operation and performs an operation for normal reproduction. At the same time, the transmission of the muting control signal Cm is stopped, and the muting section 50 is made to stop the muting operation.

As a result, the part to which T, L, start T, A specified by the mode barcode is attached in the classified program information recorded with the TNO specified by the mode barcode, That is, playback is started from the characteristic part of the program information corresponding to all the sentences in a specific item in the text 16, and the D/A converter 49 starts playing the first and second channels related to the playback. Program information 1gAL and AR are obtained, and are led out to reproduction output terminals 51 and 52 via a muting section 50.

In this way, the information reproducing operation section assumes the T, L, mode state, and uses the T, L, mode in the classified program information recorded with the TNO specified by the T, L, mode bar code. Playback starts from the part marked with start T or A specified by the barcode, and the playback program information of the first and second channels related to that playback @
In the state where AL and AR are led out to the reproduction output terminals 51 and 52, the central control block 62 receives the selected reproduction address data D and the specified address data from the comparison calculation circuit 64.
The calculation data DO obtained based on the comparison with the portion containing TNO and the end T, A in the data Dx is monitored, and the calculation data D is calculated.

indicates that the selected playback address data D matches the portion of the specified address data Dx containing TNO and end T, A, that is, T
, L, T, L, in the classification program information recorded with the TNO specified by the mode barcode.
Start T, A, and end ゛T specified by mode barcode.

When the reproduction from the portion specified by A is completed, the central control block 62 controls the information reproduction operation section to take a pause state.

The pause state taken by the information reproducing operation unit described above is based on the key data K obtained by operating the data input keys 26 or based on the reading of the barcode 14 placed on the text 16 by the barcode reading unit 30. The control data Bb from the control data generating section 65 obtained by the control data generation section 65 is maintained until it is input to the central control block 62.

In addition, when the data input key 26 is operated and the key manual data K is input to the first input terminal (2) of the central control block 62, the central control block 62 gives the muting control to the muting unit 50. When the signal Cm is supplied and the muting operation state is established, the central control block 62 selects TNO, the combination of TNO and INDEX specified by the key manual data K, or the combination of TNO and T, A. Specified address data Dx as contents is formed. The specified address data Dx formed in accordance with the key manual data K is supplied to a comparison calculation circuit 64, and in the comparison calculation circuit 64, the above-mentioned information reproduction operation section determines TR, L, mode status, 1.
A comparison similar to the comparison between the selected reproduction address data D and the specified address data Dx in the comparison calculation circuit 64 is performed when the L, L, mode state or T, L, mode is set, and based on the comparison, the information is The playback operation part is T
R, L, mode state, 1. L, mode state or T,
In the same way as when the optical head 43 is in the L mode state, after the optical head 43 enters a state in which it performs a search operation, it performs an operation for normal reproduction.

Then, when the optical head 43 enters a state to perform an operation for normal playback after the search operation, the central control block 62 stops sending out the muting control signal Cm to stop the muting operation in the muting section 50, The information reproducing operation section is set to play from the beginning of the classified program information recorded with the TNO specified by the key manual data K (TN○ specified reproduction mode state), specified by the key manual data K. A (IN
(DEX specified playback mode state), or T, A specified by the key manual data K in the classified program information recorded with the TNO specified by the key manual data K.

A state in which playback is performed from the part specified by (T, A
, designated playback mode state), and this state continues until the reading position by the optical head 43 reaches the end of reading on the disc 41, and the reading position by the optical head 43 continues until the reading position on the disc 41 reaches When the end point is reached, the information reproducing operation unit is caused to take a stop state.

When the information reproducing operation section is brought to a stop state, the motor 42 is stopped, the rotation of the disk 41 is stopped, and the light beam from the optical head 43 is not irradiated.
