- the file is designated and the process returns to step S30.
- step S60 when CPU 10 determines in step S60 that the file type symbol of the file name to be reproduced is not A, it determines whether or not the file type symbol is C in step S150. If CPU 10 determines that this is the case, the process proceeds to step S160. If CPU 10 determines that this is not the case, the process proceeds to step S180.
- step S160 the CPU 10 reproduces the file designated as the reproduction target, and proceeds to step S170.
- step S160 if the count value of the counter is 2, the CPU 10 proceeds to step S170 after the file is reproduced, and otherwise skips the reproduction of the file. The process proceeds to S170.
- step S170 the CPU 10 designates, as a new reproduction target file, a file having the first two digits of the file name updated by adding 1 to the first two digits, and returns the process to step S30.
- step S180 the CPU 10 determines whether or not the file type symbol of the file currently designated as the reproduction target is D. If so, the process proceeds to step S190, and if not, the CPU 10 determines that it is not. The process proceeds to step S210.
- step S190 the CPU 10 determines whether or not the file reproduced immediately before is a file having a value one lower than the first two digits of the current file to be processed as the first two digits. If it is determined that there is, the process returns to step S80. On the other hand, when determining that this is not the case, the CPU 10 advances the processing to step S200.
- step S200 the CPU 10 reproduces a file designated as a reproduction target (a file whose file type symbol is D) three times in succession, and ends the reproduction process three times.
- step S210 as in step S190, the CPU 10 determines whether or not the file reproduced immediately before is a file having a value one lower than the first two digits of the file to be processed as the first two digits. If so, the process returns to step S80. On the other hand, when determining that this is not the case, the CPU 10 advances the processing to step S220.

図2を参照して、ページ900には、画像901の他に、画像902~905が印刷されている。再生装置1では、画像901を撮影することにより生成された画像を認識して、認識された画像データを、ファイルを指定する情報に変換する。そして、再生装置1では、当該指定されたファイルが再生される。
図3は、再生装置1のブロック図である。
本実施の形態では、コンテンツの一例として、学習用教材に関連した音声ファイルが挙げられる。本実施の形態において、ファイル記憶部43には、次の表1に示されるように音声ファイルが格納される。
表1を参照して、説明したように、本実施の形態の音声ファイルのファイル名の3桁目には、再生に関する種別を表わす情報が配置されている。具体的には、大文字のアルファベットが配置されている。
再生装置1における、1回再生モードでのファイルの再生について、具体的に説明する。
次に、トラック単位フォルダ内の全部または一部のファイルを3回繰返して再生させる処理(3回再生処理)について、当該処理のフローチャートである図6および図7を参照して説明する。
そして、トラック単位フォルダ内の、最大の番号(先頭2桁の数字)を有するファイルが再生対象として指定されるまで、ステップS110で先頭2桁の数字が1加算更新されて新たな再生対象のファイルが指定される。これにより、図8に再生順序3、4、5として示すように、ファイル名「03A」「04A」「05A」が、順に、再生される。
新たに指定された再生対象のファイルのファイル種別記号が、Cであるため、ステップS30、ステップS60、ステップS150を経て、処理はステップS160へ進められる。
そして、処理は、ステップS30へ戻される。
再生装置1は、複数の音声ファイルが、予め定められた順番通りに再生対象として指定されたことを条件として、特定のファイルを再生することができる。このような再生に対応したテキストの表示内容を、図9に模式的に示す。
再生装置1は、トラック単位フォルダに格納される複数のファイルの中で、不正解のグループに属するファイルが1つも指定されることなく、正解に属するグループのファイルをすべて再生対象として指定されたか否かによって、ユーザからの再生対象の指定に対して、再生するファイルを決定することができる。
図11に、ランダム再生に対応するテキストの内容を表示する。テキストのページ800には、音声の再生を開始するための画像801が含まれている。
表7に、ページ800に対応する、トラック単位フォルダに格納されたファイルの内容を示す。
以上説明した本実施の形態では、再生対象として指定を受付けたファイルのファイル名から、識別情報(音声ファイルのファイル種別記号および/または先頭2桁の数字)が検出され、当該検出された識別情報に基づいて、指定を受付けたファイルのファイル名が指定条件を満たすか否かによって、当該指定されたファイルの次に再生されるファイルが指定される。これにより、最初に再生対象として指定されたファイルのファイル名に基づいて、その後に再生されるファイルが決定される。これにより、指定を受付けたファイルに基づいて、ファイルの再生パターンを種々変更することができ、装置に対して設定を変更することなく、よりバリエーションに富んだ再生パターンで、複数のファイルを再生することができる。
