The CPU 110 links each chapter element to the lower order of the parent element of the original work as the original work tree structure data 1311 (step S110).

  The CPU 110 specifies the start position of the text of the original work data 131 based on the original work data 131 (step S112). The CPU 110 reads the next sentence from the original data 131 (step S114). CPU 110 identifies the type of sentence based on symbols (key brackets and question marks) included in the sentence (step S116). The CPU 110 stores the sentence type and the sentence position in the memory 130 as the original tree structure data 1311 (step S118).

  CPU 110 determines whether a chapter element has already been created based on the table of contents (step S120). If a chapter element has already been created based on the table of contents (YES in step S120), CPU 110 determines whether there is a line break before the currently targeted sentence (step S122). If there is a line break before the target sentence (YES in step S122), CPU 110 executes the processing from step S130. If there is no line break before the target sentence (NO in step S122), CPU 110 executes the processing from step S134.

  If the chapter element has not yet been created based on the table of contents (NO in step S120), CPU 110 determines whether there is a page break before the target sentence (step S124). If there is no page break before the target sentence (NO in step S124), the processing from step S122 is repeated.

  If there is a page break before the target sentence (YES in step S124), CPU 110 creates a tree structure element of the chapter including the target sentence (step S126). The CPU 110 links the tree structure of the target chapter below the parent element (step S128).

  The CPU 110 creates a tree structure element (paragraph element) of the target paragraph (step S130). The CPU 110 links the target paragraph element to the lower level of the target chapter element (step S132). The CPU 110 links the target sentence tree structure (sentence element) below the target paragraph element (step S134).

  The CPU 110 determines whether or not easy information (numerical value, date, proper noun, symbol, designated character, etc.) for facilitating specification of the sentence is included in the target sentence (step S136). . If easy information is not included in the target sentence (NO in step S136), the processing from step S142 is executed.

  If easy information is included in the target sentence (YES in step S136), CPU 110 creates a tree structure element of the information (step S138). CPU110 links the said information to the subordinate of the sentence element used as object (Step S140).

  The CPU 110 determines whether or not the target sentence is the last sentence of the original data 131 (step S142). If the target sentence is not the last sentence of the original data 131 (NO in step S142), the processing from step S114 is repeated. When the target sentence is the last sentence of original data 131 (YES in step S142), CPU 110 ends the original analysis process.

<Page turning process>
Below, the page display process performed by CPU110 is demonstrated. FIG. 9 is a first flowchart showing a page display process according to the present embodiment. FIG. 10 is a second flowchart showing page display processing according to the present embodiment. CPU110 performs the following processes, when the command which displays an electronic book is received.

  Referring to FIGS. 9 and 10, when CPU 110 receives an instruction to display an electronic book (hereinafter referred to as an original), whether or not a translation is already associated with the original to be displayed. Is determined (step S202). If the translated document is associated with the original work (YES in step S202), the processing from step S204 is executed.

  CPU110 performs a document designation | designated process (step S500), when the translation is not matched with the original work (when it is NO in step S202). The document designation process will be described later. When the document specifying process (step S500) is completed, the CPU 110 displays the original page on the display 121 (step S204). For example, the CPU 110 reads the original page displayed last time last time and displays the page on the left side of the display 121.

  CPU110 performs a link process (step S400) regarding the displayed original page. The link process (step S400) will be described later. When the link process (step S400) ends, the CPU 110 displays the translated document page specified by the link process on the right side of the display 121 (step S206).

  CPU 110 determines whether or not a touch operation is input via touch panel 120 (step S212). CPU110 repeats the process of step S212, when the touch operation is not input (when it is NO in step S212).

  When a touch operation is input (YES in step S212), CPU 110 determines whether an instruction for designating a part of the original work has been received (step S214). CPU110 judges whether the command for designating a sentence was received, when the command which designates a part of original work was received (when it is YES in step S214) (step S216). More specifically, when any sentence of the original book is touched (clicked), CPU 110 determines that an instruction for selecting the sentence has been received.

  CPU110 performs the link process (step S400) regarding the said sentence, when the command for selecting the said sentence is received (when it is YES in step S216). When the link processing (step S400) is completed, CPU 110 changes the display mode of the translated sentence corresponding to the designated sentence (step S220).
