1. A display input device comprising:
- a display portion that displays a list;
a touch panel portion that is provided in the display portion and that detects a touch position touched by a user; and
a processing portion,wherein, while the display portion displays the list, a scroll operation that is an operation of moving the touch position after the touch of the touch panel portion and of thereafter cancelling the touch of the touch panel portion is performed such that the touch panel portion receives an instruction to scroll the list,the processing portion determines, when the scroll operation is performed on the touch panel portion, an operation start position where the touch is first performed and an operation completion position where the touch is cancelled, and calculates an inclination angle of the scroll operation direction that is an angle formed by a line extending from the operation start position in a previously determined direction and a line connecting the operation start position and the operation completion position, andwhen the scroll operation is performed on the touch panel portion, the display portion changes a scroll width at which the list is scrolled such that the scroll width equals a scroll width associated with an angle range including the inclination angle of the scroll operation direction among a plurality of angle ranges previously determined.

Abstract
While a display portion displays a list, a scroll operation that is an operation of moving a touch position after the touch of a touch panel portion and of thereafter cancelling the touch of the touch panel portion is performed such that the touch panel portion receives an instruction to scroll the list, and, when the scroll operation is performed on the touch panel portion, the display portion changes a scroll width at which the list is scrolled according to a scroll operation direction that is a direction in which the touch position is moved at the time of the scroll operation.

2. A display input device comprising:
-
a display portion that displays a list; a touch panel portion that is provided in the display portion and that detects a touch position touched by a user; and a processing portion, wherein a total number of display targets listed in the list is variable, while the display portion displays the list, a scroll operation that is an operation of moving the touch position after the touch of the touch panel portion and of thereafter cancelling the touch of the touch panel portion is performed such that the touch panel portion receives an instruction to scroll the list, the processing portion determines, when the scroll operation is performed on the touch panel portion, an operation start position where the touch is first performed and an operation completion position where the touch is cancelled, and calculates an inclination angle of the scroll operation direction that is an angle formed by a line extending from the operation start position in a previously determined direction and a line connecting the operation start position and the operation completion position, the processing portion determines the total number of display targets listed in the list and calculates, based on the total number of display targets listed in the list, scroll widths associated with the previously determined angle ranges, and when the scroll operation is performed on the touch panel portion, the display portion changes a scroll width at which the list is scrolled such that the scroll width equals a scroll width associated with an angle range including the inclination angle of the scroll operation direction among a plurality of angle ranges previously determined.

6. A display input device comprising:
-
a display portion that displays a list; and a touch panel portion that is provided in the display portion and that detects a touch position touched by a user, wherein, while the display portion displays the list, a scroll operation that is an operation of moving the touch position after the touch of the touch panel portion and of thereafter cancelling the touch of the touch panel portion is performed such that the touch panel portion receives an instruction to scroll the list, when an operation is performed of moving the touch position after the touch of the touch panel portion in a previously determined scroll operation reception position within a screen on which the list is displayed and of thereafter cancelling the touch of the touch panel portion, the touch panel portion receives the operation as the scroll operation whereas, when an operation is performed of moving the touch position after the touch of the touch panel portion in a position other than the previously determined scroll operation reception position and of thereafter cancelling the touch of the touch panel portion, the touch panel portion does not receive the operation as the scroll operation, and when the scroll operation is performed on the touch panel portion, the display portion changes a scroll width at which the list is scrolled according to a scroll operation direction that is a direction in which the touch position is moved at a time of the scroll operation.
