A touch panel type operation device, comprising: a display device that displays a selectable object (61, 64 to 68); a touch panel that is placed on a display area of the display device and accepts a touch operation of a user; a touch-on detection unit that detects a touch-on where a state in which the user is not touching the touch panel transits to a state in which the user is touching the touch panel; a touch-off detection unit that detects a touch-off where the state in which the user is touching the touch panel transits to the state in which the user is not touching the touch panel; a touch coordinate acquisition unit that, if the user is touching the touch panel, acquires a touch coordinate that is a coordinate of a point where the user has touched; a selection unit that selects the selectable object corresponding to the touch coordinate acquired by the touch coordinate acquisition unit; and a scroll-display unit that scroll-displays on the display device the selectable object being selected by the selection unit, based on a displacement of the touch coordinate acquired by the touch coordinate acquisition unit; characterized in that the touch panel type operation device comprises: a touch-off determination time setting unit that sets a touch-off determination time; a touch-off determination unit that determines occurrence of the touch-off if the state in which the user is not touching the touch panel has continued for the touch-off determination time or more after the touch-off was detected by the touch-off detection unit; a displacement judgment unit that judges whether the touch coordinate acquired by the touch coordinate acquisition unit just before the touch-off was detected by the touch-off detection unit is displaced, and in that the touch-off determination time setting unit, if the displacement judgment unit has judged that the touch coordinate acquired by the touch coordinate acquisition unit just before the touch-off was detected is displaced, sets the touch-off determination time longer than if the displacement judgment unit has judged that the touch coordinate acquired by the touch coordinate acquisition unit just before the touch-off was detected is not displaced. a display device that displays a selectable object (61, 64 to 68);
