Display screen operation device

摘要

In a state in which any one of selection buttons is selected (state in which a color is reversed), a touch panel in a controller is operated, and, the selected state of the selection button is released when an operation signal from the above controller is corresponding to a moving trajectory from a gray zone to another gray zone through a cancellation zone. Thereby, unnatural feeling at operation caused by distance between a finger position on the touch panel of the controller and a position of the selection button in the selected state is reduced or eliminated.
