The concept of a reference button is defined in the electronic book, and it is possible to call up the contents related to the displayed text. With this function, it is possible to refer to synonyms and objections, and it is possible to continuously display various scenes on a disk for English conversation.

Further, in the electronic book, it was possible to return to the previously displayed screen (hereinafter, this function will be called return).

[0008]

However, since this return function is a function of displaying the screen displayed immediately before that screen is displayed, it has a problem in that it is inconvenient for the user.

For example, now, A, B, C, D, B
The screens are displayed in the order of, and the screen B is currently being displayed. At this point, when the user requests a return, the user thinks that B, C, D, and B have made a round, so screen A
Although it is considered to return to, the screen actually returns to the screen D displayed immediately before. As described above, since the operation is different from the user's expectation, there is a problem in that the usability of the user is poor.

When a series of displays are performed by using the reference function and the screen returns to the first screen, the screen immediately before that is returned when the screen is restored, and it is impossible to return to the logical previous screen. There was a problem.

[0011]

[Means for Solving the Problems] A function of storing a displayed screen and a function of determining whether a newly displayed screen matches a stored screen. It consists of the function to transit to the screen.

[0012]
