The interruption page count M is the number of pages at which a series of photographing operations is interrupted, and is the number of times of page turning operations of the automatic page turning apparatus 3. Note that, when displaying the operation screen G in Step SA1, the control section 25 displays, on the operation screen G, a specified value in the second input box 102 or a changed value of a specified value in the previous use of the divisional photographing mode, and an interruption interval T corresponding to the changed value.

When a new interruption page count M is inputted to the second input box 102 (YES at Step SA4), the control section 25 calculates a corresponding interruption interval (time), and stores the new interruption page count M and the interruption interval T in the storage section 26 while displaying the calculation result T on the operation screen G (“4 min” in FIG. 7) (Step SA5). Note that the interruption interval T is calculated by multiplying the time required for turning one page by the automatic page turning apparatus 3, or more specifically, the time secured for an optimal page turning operation, by the interruption page count M.
