DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information selective reproducing apparatus capable of selectively reproducing a desired portion of recorded program information from a disc which is an information recording medium on which the program information is recorded. .

[0002]

2. Description of the Related Art A digital audio disk (hereinafter referred to as DAD) having a spiral recording track formed by digitizing an audio signal and recording it as program information on a rotating disk-shaped recording medium is used. A DAD system in which a disc player reproduces an audio signal, which is program information recorded in a DAD, has been proposed as an audio signal reproducing system capable of obtaining a high-quality reproduced audio signal.

In such a DAD, for example, two-channel program information as left and right signals forming a stereo music signal is recorded, and a disc player for reproducing the program information transmits the two-channel program information from the DAD. That is, the left and right signals forming the stereo music signal can be obtained separately and simultaneously. In the DAD, the program information of, for example, two channels recorded therein takes the form of an aggregate of a plurality of section program information corresponding to each music piece and the like, and is accompanied by address data. It is said. This address data indicates, for example, the recording arrangement order from the reproduction start end side of each section program information.
Usually, data called a track number (hereinafter, TN)
O), data which is usually referred to as an index (hereinafter referred to as INDEX), which represents the order of subdivisions in one section program information, and reproduction time from the beginning of one section program information. For example,
It includes various data such as time data (hereinafter, referred to as TA) expressed in units of minutes, seconds, and 1/75 seconds called frames.

[0004] In general, the DAD is such that when the innermost periphery of a spiral recording track is a reproduction start end and the outermost periphery is a reproduction end, a normal reproduction by a disc player is performed. In order to perform the playback operation from the center of the disc to the outer periphery,
The read head of the disc player is moved. In reproducing the program information from the DAD in this manner, the address data as described above is recorded along with each piece of program information. By moving the head to a desired recording position on the disc, for example, a position where the specific division program information is recorded, the specific division program information and the subsequent division program information can be selectively reproduced, and The read head can be moved to a desired recording position on the disk very quickly.

[0005] Taking advantage of the features of such a DAD system,
For example, a training DAD in which program information corresponding to the content of a foreign language training text in which a foreign language and a translation for the foreign language are described is prepared, and the learner transfers the text content to the training DAD. It is conceivable to configure an educational device that enables learning by using the reproduction of recorded program information by a disc player. Training DADs used in such educational devices are:
The contents of the text, for example, the entire plurality of sentences in each of the items constituting the text is recorded as the segmented program information, and each of the plurality of sentences in each item is recorded as a subdivision in the segmented program information. When recording
TNO that is to be changed sequentially for each of a plurality of sentences in each item, INDEX that is to be changed for each of a plurality of sentences in one item, and a plurality of T. which gradually changes throughout the text A. And address data including the following. Therefore, when reproducing the program information corresponding to the contents of the text from the training DAD by the disc player, reproduction from a desired item and reproduction of a desired item in a plurality of sentences in a specific item are performed using reproduction address data. Reproduction from one or reproduction of a plurality of sentences in a specific item from a desired position can be performed.

[0006]

However, in an educational apparatus using the above-described disc player, the address information recorded in the training DAD is used to store the program information recorded in the training DAD. In performing selective reproduction from a specific location, the TNO and INDEX or T.D.
A. It is necessary to input data such as address data by operating a data input key provided on the disc player. Therefore, when the learner learns the contents of the text together with the reproduction of the program information recorded in the training DAD by the disc player, the learner frequently operates the data input keys provided on the disc player. The user has to take his eyes off the text, and the user is liable to make an error in the input operation of the address data.

Further, in the conventional disc player, the program information recorded in the DAD is subdivided into the divided program information with the selected TNO and the divided program information with the selected TNO and INDEX. , Or the selected T.D. in the segmented program information appended with the selected TNO. A.
In the case where reproduction from the part specified by is performed, after the reproduction of the specific program information part is completed, each of the segmented program information recorded subsequently to the specific program information part is recorded on the recording medium. Reproduction is performed sequentially according to the arrangement order. For this reason,
For example, as in a case where the text is a foreign language training text and a foreign language is learned, each of a plurality of sentences in each item of the text is relatively short, and the relatively short text from the disc is used. If it is desired to reproduce only the subdivision of the division program information corresponding to each sentence described above, the reproduction operation of the disc player is promptly stopped when the reproduction of the subdivision of the division program information is completed. However, there is an inconvenience that a troublesome operation on the disc player is required.

In view of the above, the present invention relates to a method for storing text having contents corresponding to program information recorded on a disk with address data and program information recorded on a disk with specific address data. Information reproduction operation means that can be selectively reproduced, the operator can perform the operation according to the content of the text by a very simple operation that can be performed without taking an eye on the text,
It is an object of the present invention to provide an information selective reproducing apparatus suitable for use as an educational device, capable of reproducing only a desired portion of program information recorded on a disc by an information reproducing operation means.

[0009]

In order to achieve the above object, an information selective reproducing apparatus according to the present invention has a character or picture corresponding to program information recorded on a disk together with address data. At the same time, a bar code including address information representing address data recorded on the disk is read in close proximity to these characters or pictures, and the bar code allocated to the text is read and recorded on the disk. A bar code reading unit for issuing control data including address information representing the selected address data, and a data input key unit for issuing key input data corresponding to the address information representing the address data recorded on the disk in response to an operation And an information reproducing operation unit connected to each of the bar code reading unit and the data input key unit. Raw operation portion, according to the key input data from the control data or data input key unit from the bar code reader, a row physician playback of portions with a particular address data of the program information recorded in the aforementioned disk At that time, key input from the data input key section

Priority over control according to the control data according to the bar code
It is supposed to operate and configured.

[0010] In addition, the information selecting playback equipment according to the present invention,
Specifically , the information reproducing operation unit determines whether the input data is either key input data from the data input key unit or control data corresponding to the bar code read by the bar code reading unit. And control means for selectively performing control in accordance with key input data and control in accordance with the control data, and the control means reads the control in accordance with the key input data from the data input key section by the barcode reading section. The priority is given to the control according to the control data corresponding to the barcode.

[0011]

In the information selecting / reproducing apparatus according to the present invention configured as described above, when an operator operates the data input key section, key input data corresponding to the operation is supplied to the information reproducing operation section. The information reproducing operation unit takes an operation state of reproducing a portion accompanied by specific address data of the program information recorded on the disc according to the key input data, and is freely operated by the operator, for example, with one hand. When an operation of reading a specific barcode arranged in the text is performed by a barcode reading unit formed in a pen shape that can be handled, control data corresponding to the read barcode is supplied to the information reproducing operation unit. The information reproducing operation unit reads the text of the program information recorded on the disc in accordance with the address information represented by the control data. Take the operating state for the issued bar code to play a part corresponding to the character or picture is intended to be placed in close proximity.
