What is claimed is:1. An apparatus for controlling page turning, comprising:an interruption section which repeatedly interrupts a page turning operation of a page turning apparatus, which mechanically turns a page serving as an imaging target, at predetermined equal interruption intervals, wherein the predetermined interruption intervals are predetermined such that a plurality of pages are turned between interruptions of the page turning operation; anda restarting section which, every time the page turning operation of the page turning apparatus is interrupted, restarts the page turning operation in response to a restart instruction by a user.2. The apparatus according to claim 1, further comprising:a processor which functions as the interruption section and the restarting section.3. The apparatus according to claim 1, further comprising:a storage section which stores interruption information for determining the interruption intervals,wherein the interruption section interrupts the page turning operation of the page turning apparatus at the interruption intervals, which are determined based on the interruption information stored in the storage section.4. The apparatus according to claim 3, further comprising:a setting section which prompts the user to set the interruption information for determining the interruption intervals,wherein the storage section stores the interruption information set by the setting section prompting the user.5. The apparatus according to claim 4, wherein the setting section prompts the user to set, as the interruption information, one of a page count and an interruption interval time period.6. The apparatus according to claim 4, further comprising:a display section which displays the interruption information.7. The apparatus according to claim 1, wherein a specific control mode is provided as a control mode for controlling the page turning apparatus, andwherein the interruption section in the specific control mode interrupts the page turning operation of the page turning apparatus at specified interruption intervals, and the restarting section restarts the page turning operation of the page turning apparatus interrupted by the interruption section.8. A method for controlling page turning, comprising:repeatedly interrupting a page turning operation of a page turning apparatus, which mechanically turns a page serving as an imaging target, at predetermined equal interruption intervals, wherein the predetermined interruption intervals are predetermined such that a plurality of pages are turned between interruptions of the page turning operation; andevery time the page turning operation of the page turning apparatus is interrupted, restarting the page turning operation in response to a restart instruction by a user.9. The method according to claim 8, further comprising:storing interruption information for determining the interruption intervals in a storage section,wherein the interrupting interrupts the page turning operation of the page turning apparatus at the interruption intervals, which are determined based on the interruption information stored in the storage section.10. The method according to claim 8, further comprising:prompting the user to set, as interruption information for determining the interruption intervals, one of a page count and an interruption interval time period.11. The method according to claim 8, wherein a specific control mode is provided as a control mode for controlling the page turning apparatus, andwherein the interrupting interrupts the page turning operation of the page turning apparatus at specified interruption intervals in the specific control mode, and the restarting restarts the page turning operation interrupted in the page turning apparatus.12. A non-transitory computer-readable storage medium having a program stored thereon that is executable by a computer to actualize functions comprising:repeatedly interrupting a page turning operation of a page turning apparatus, which mechanically turns a page serving as an imaging target, at predetermined equal interruption intervals, wherein the predetermined interruption intervals are predetermined such that a plurality of pages are turned between interruptions of the page turning operation; andevery time the page turning operation of the page turning apparatus is interrupted, restarting the page turning operation in response to a restart instruction by a user.13. The storage medium according to claim 12, wherein the program further causes the computer to store interruption information for determining the interruption intervals in a storage section, andwherein the interrupting interrupts the page turning operation of the page turning apparatus at the interruption intervals, which are determined based on the interruption information stored in the storage section.14. The storage medium according to claim 12, wherein the program further causes the computer to prompt the user to set, as interruption information for determining the interruption intervals, one of a page count and an interruption interval time period.15. The storage medium according to claim 12, wherein the program further causes the computer to provide a specific control mode as a control mode for controlling the page turning apparatus, andwherein the interrupting interrupts the page turning operation of the page turning apparatus at specified interruption intervals in the specific control mode, and the restarting restarts the page turning operation interrupted in the page turning apparatus.16. An apparatus for controlling page turning, comprising:a setting section which prompts a user to set a page count as interruption information;a derivation section which derives an interruption interval of a series of page turning operations of a page turning apparatus, which mechanically turns a page serving as an imaging target, based on the page count set by the user;an interruption section which interrupts the series of page turning operations of the page turning apparatus, at equal interruption intervals to the interruption interval derived by the derivation section;a restarting section which, every time the series of page turning operations of the page turning apparatus are interrupted, restarts the series of page turning operations in response to a restart instruction by the user; anda display section which displays the page count and the interruption interval derived by the derivation section.17. An apparatus for controlling page turning, comprising:a first interruption section which repeatedly interrupts a series of page turning operations of a page turning apparatus, which mechanically turns a page serving as an imaging target, at a predetermined equal interruption intervals;a second interruption section which interrupts the series of page turning operations of the page turning apparatus, in response to an interruption instruction given by a user, regardless of the interruption intervals; anda restarting section which restarts the series of page turning operations of the page turning apparatus interrupted by the first interruption section or the second interruption section in response to a restart instruction by the user.
