Portable terminal, display control program and display control method

A non-transitory display control program that is used in a portable terminal having a display that displays a display item and a touch panel that displays a display item and detects contact made thereon, the non-transitory display control program comprising:

• a detection step of detecting a first contact point and a second contact point at different positions on the touch panel;
• a determination step of, when the detection step detects the first contact point and the second contact point, determining whether or not the first contact point moves before release of at least one of the first contact point and the second contact point, and further determining, only when determining that the first contact point has moved before release of at least one of the first contact point and the second contact point, whether or not a change in a relative position of the second contact point with respect to the first contact point, before the movement of the first contact point is smaller than a predetermined amount and after the movement of the first contact point is smaller than a predetermined amount;
• and a display control step of, when the determination step determines that the change in the relative position of the second contact point with respect to the first contact point, before the movement of the first contact point is smaller than the predetermined amount and after the movement of the first contact point is smaller than the predetermined amount, specifying, according to a direction of the movement of the first contact point, a position on the display to which a first display item is to be moved and a position on the touch panel to which a second display item is to be moved, the first display item being displayed on the display prior to the movement of the first contact point and the second display item being displayed on the touch panel prior to the movement of the first contact point, and displaying the first display item at the position on the display to which the first display item is to be moved and display the second display item at the position on the touch panel to which the second display item is to be moved.
