  The photo sensor reads the barcode (210) by continuously moving the voice card (200), and transmits address information (for example, 0, 0) including characters to the MCU (70) (S130). ). When the MCU receives the address information, it reads the audio information corresponding to the track address 0 and the index address 0 stored in the voice card information in the memory (S140), and the read audio information is converted into a digital information processing unit (decoder, 50). (S150). The decoder (50) converts the sound information into analog sound and reproduces the analog sound through the speaker (60) (S160, S170).

  Furthermore, when the user wants to listen to the Korean language corresponding to the printed picture, the card voice card moving unit (30) is inserted by inserting the back side of the voice card printed with the Korean language into the voice card insertion unit (110). When driven, the audio data is played back by the same interaction relationship as the front of the voice card.

  The above embodiment relates to a voice card in which one bar code is formed on each of the front and back surfaces of the voice card. However, a plurality of bar codes may be formed on the front and back surfaces of the card. For example, for the same character and symbol, the front of the voice card is printed with alphabets and barcodes corresponding to Japanese characters, and the back of the voice card is printed with other barcodes corresponding to Korean characters. It may be printed so that three languages are learned with one voice card. In such a case, as illustrated in FIG. 5, the voice card moving unit (30) moves the voice card, so that the voice information stored in the voice card is stored in the voice card information storage unit in the memory of the player according to the present invention. Can be reproduced in English stored in track address 0 and index address 0, in Korean stored in track address 1 and index address 0, and in Japanese stored in track address 2 and index address 0.

  As shown in FIG. 3, an example of a player control procedure when using an audio book according to the present invention is as follows. In this embodiment, an example in which an electronic pen method and a hall sensor method are used in combination will be described.

  When the audio book (200) is placed on the book support unit (130) of the player main body (100) and the power is turned on, the hall sensor of the audio book page sensing unit (20) sends a sensing signal to the MCU (70). When the page recognition display is marked using the electronic pen (120), a sensing signal is sent to the MCU (70) (S210). Upon receiving the Hall sensor detection signal and / or the electronic pen detection signal (S220), the MCU 70 determines the page address of the audio book corresponding to the signal (S230). Then, the audio data of the audio book corresponding to the address determined in step S230 is sent to the digital information processing unit (S240). The audio data decoded by the digital information processing unit is output through a speaker (S250, S260).

  When the Hall sensor method and the electronic pen method are used together as described above, the number of audio books is identified by the Hall sensor detection signal, and the page and the content to be output by the electronic pen detection signal input by the user's operation are displayed. It will be possible to judge. That is, the voice card may be inserted without interrupting the output of words and sentences included in the audio book by marking the recognition display in the page of the audio book. FIG. 4 shows an embodiment in such a case. As shown in the figure, when a voice card is inserted during output of an audio book and an insertion signal from the photo sensor is input to the MCU (S310, S320), the MCU 70 is decoded by interrupting the audio output of the audio book. The remaining data is stored in the buffer (S330, S340, S350). In addition, the voice card mode as shown in FIG. 3 is executed (S360). That is, the card moving unit (30) is driven to receive a signal input from the voice card sensing unit, determine the barcode based on the signal, and set the address of the voice card audio data corresponding to the barcode. After the determination, the audio data of the voice card corresponding to the determined address is sent to the digital information processing unit, the audio data is decoded, and the audio data decoded by the speaker is output. Then, the MCU 70 determines whether the output of the decoded audio data of the voice card is completed (S370), and if it is determined that the output is completed, outputs the data stored in the step S350 through the speaker.
