CONSTITUTION:When the finger touches any of each contact point of a touch switch having plural contact points in a lattice shape corresponding to the screen of CRT (the step 4 is 'YES'), whether or not the contact point is included in any operation area A1 or A10 which is specified in the display screen (the step 6), and when it is included, the contact operation area is stored in the area N (the step S8). When the finger does not come in contact with any contact point (the step S4 is 'NO'), the switch corresponding to the storage value in the area N is operated (the step S12).</p> |
