PROBLEM TO BE SOLVED: To solve inconvenience that may occur when erasing data stored in an auxiliary storage device.SOLUTION: A terminal device comprises first selection accepting means, storage means, second selection accepting means and erasing means. When storing new data in a storage region that an auxiliary storage device has, the first selection accepting means accepts any one selection from indexes allocated to a plurality of sub regions included in the storage region. The storage means stores the new data in a region corresponding to the index of which the selection is accepted by the first selection accepting means. When erasing data from the storage region, the second selection accepting means accepts any one selection from the indexes allocated to the sub regions. The erasing means collectively erases the data stored in the region corresponding to the index of which the selection is accepted by the second selection accepting means. |
