Abstract
In an electronic apparatus having a membrane switch and a touch panel switch at its entirety section, the touch panel switch is elastic and is laid over the membrane switch. The two-layered structure provides users with two operations: a “finger-sliding” operation and a “finger-depressing operation.” When a user slides a finger on the surface of the touch panel switch, the sliding force activates the touch panel switch. The “finger-sliding” is used for selecting a desired item. On the other hand, when the user presses down on the surface of the touch panel switch, the depression force through the touch panel switch activates the underlying membrane switch. The “finger-depressing” is used for numeric or symbolic information entry. It is thus possible to realize an electronic apparatus offering an excellent compromise between ease of operation and a wide display section.
