Abstract
In an analog input device, a rubber member is provided between a key top and a movable electrode of an analog-quantity generating unit. A dead zone can be removed or reduced by forming a bottom portion of the rubber member of a flat or curved face. Furthermore, since first round surfaces are connected to an outer side face, the linearity of the input (e.g., a load)-output (voltage) characteristic can be enhanced.
