Note that an automatically stopped turning operation may be automatically restarted at timing at which the time elapsed from the stop time point of a turning operation has reached a predetermined waiting time instead of the timing of the issuance of a photographing start instruction by the user. In this case as well, the apparatus may be configured to receive a photographing start instruction from the user and, when a photographing start instruction is received from the user before the time elapsed from the stop time point of a page-turning operation reaches the waiting time, the apparatus may restart the page turning operation at this time point.
Also, the page turning operation of the automatic page turning apparatus 3 is stopped at an arbitrary time point in response to an interruption instruction from the user even if the sequential page-turning count m has not reached the interruption page count M. Accordingly, it is possible to deal with a situation in which a page state on a page-turning end point side has deteriorated against the user's expectation before the sequential page-turning count m reaches the interruption page count M, which also improves convenience in addition to workability in photographing a series of pages.
In the present embodiment, the tablet 2 executes the book management program. However, the present invention is not limited thereto. The function according to the present invention can also be actualized by supplying a program which can actualize the same processing as that actualized by the book management program to other information devices such as a general personal computer. In addition, an arbitrary program supply method can be used. For example, a program may be supplied from a Web page on the Internet to a personal computer or the like.
