To visually, tactually and easily recognize touching and operating of a desired touch operation area in a display image plane having a touch panel.
When touching an operation button (Step 100 to 102) displayed in an initial form by the display image plane (P1 ≤ P < P2 : Step 102), processing B of changing a display color of the operation button is performed (Step 104), and driving 1 of retracting the display image plane small is performed (Step 105). When further pushing in this operation button (P2 ≤ P : Step 108), processing C such as a determination is performed (Step 109). At the same time, driving 2 of further largely moving the display image plane to the innermost side is performed (Step 110). Thus, touching and operating of the operation button can be visually and tactually known.
