Abstract
An operation input device () includes a directional key () and coils (-). The directional key () is accommodated within a case () when a slide part () is slid in a closing direction to be in a closed state, is displaced to a position protruding from an opening part () of the case () when the slide part () slides in an opening direction to be in an open state, and is displaced inward from the opening part () when an operation input is applied while the slide part () is in the open state. The coils (-) detect the position of the directional key () in a non-tactile manner and output a signal according to the amount of displacement of the directional key (). The signal output from the coils is used to determine whether the slide part () is in the open or closed state.
