May be. In this case, when the save button is operated, the recording unit 13 stores the audio information in the backup database. Further, when the save button is operated, the conversion means 14 stores the character information in the backup database. Further, when the save button is operated, the image storage means stores the image information in the backup database. The display control means 15 also has a third predetermined operation for erasing characters and graphics displayed on the board 2 by the user at the position where the first predetermined operation is performed without operating the save button in the input / output means 6. In the case where a message is displayed, a warning display (for example, a character image “Is it really okay”) may be displayed to warn that voice information, character information and / or image information is not stored in the backup database.

  Returning to FIG. 3, the reproducing means 17 reproduces the sound of the sound information generated by the recording means 13. The reproduction unit 17 has performed a second predetermined operation (for example, an operation for indicating a character) indicating the position on the board 2 by the user at the position where the first predetermined operation has been performed from the position detected by the detection unit 3. In this case, referring to the recording DB 20 (see FIG. 4), the sound of the sound information associated with the time indicated by the position information of the position where the first predetermined operation has been performed is reproduced from the speaker 5. Further, for example, the playback unit 17 performs control such that the operation icon 64 displayed on the input / output unit 6 shown in FIG. 5 fast-forwards, rewinds, stops, etc. according to the operation by the user.

  The above-described functional configuration of the present system is merely an example, and one functional block (database and function processing unit) may be divided, or a plurality of functional blocks may be configured as one functional block. Each function processing unit reads a computer program stored in a storage device such as a ROM (Read Only Memory) or a hard disk by a CPU (Central Processing Unit) built in the computer device, and is executed by the CPU. It is realized by. That is, in each function processing unit, this computer program reads and writes necessary data such as a table from a database (DB; Data Base) stored in a storage device or a storage area on a memory, and may be related in some cases. This is realized by controlling hardware (for example, an input / output device, a display device, and a communication interface device). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but it simply means a collection of tables and files, and the internal structure of the database itself is not questioned.

Therefore, when the user wants to hear the voice uttered in relation to the character written on the board 2 in the place where the utterance is made, the user simply points to the written character and when the character is written. The spoken voice can be played back. Therefore, it is possible to quickly reproduce a desired portion of the voice in the place where the speech is made.

  In addition, the recording unit 13 performs a third predetermined operation (for example, an operation to delete the written characters) that erases characters and figures displayed on the board 2 by the user at the position where the first predetermined operation has been performed. In addition, the voice information associated with the time indicated by the position information of the position where the first predetermined operation has been performed is deleted. Thereby, the user can erase the voice uttered in association with the character only by erasing the character written on the board 2 when the utterance is made.

  The writing board 1 further includes position display means 7. The position display means 7 displays the position of the position information associated with the time indicated by the sound information on the board 2 when the reproducing means 17 is reproducing the sound of the sound information. Thereby, it can be clarified to which character the voice being reproduced corresponds to the board 2. Further, by deleting the character at the position displayed on the position display means 7, it is possible to delete the sound information of the reproduced sound, so that it is possible to prevent the erroneous sound information from being deleted.

  The writing board 1 further includes conversion means 14, input / output means 6, and display control means 15. The conversion unit 14 converts the voice information generated by the recording unit 13 into character information corresponding to the voice. The input / output unit 6 displays the character information converted by the conversion unit 14. When the second predetermined operation is performed at the position where the first predetermined operation is performed, the display control unit 15 corresponds to the time indicated by the position information of the position where the first predetermined operation is performed, which is converted by the conversion unit 14. Character information corresponding to the voice of the attached voice information is displayed on the input / output means 6. Thereby, since the user can confirm the voice information to be erased with the character information displayed on the input / output means 6, it is possible to prevent the necessary voice information from being erased.

  In addition, the recording unit 13 erases the voice information corresponding to the portion selected by the user from the character information displayed on the input / output unit 6. Thereby, since the user can delete the voice information by operating the character information displayed on the input / output means 6, only the unnecessary voice information can be surely deleted.
