Press-to-operate input device

摘要

An input device (10) includes push switches (1) allowing depressions to shallow and deep levels. Operation keys (2) of the push switches (1) are arranged in a line and exposed in an opening (8b) of a top panel (8a). A strip-like guide surface (8d) provided on the top panel (8a) forms a top surface of a ridge (8c) and extends along the line of the operation keys (2) and along one-side ends (2a) of the operation keys (2). The strip-like guide surface (8d) allows a user' finger (F) placed thereon to depress any operation key (2). The push switches (1) are each in a shallowly depressed state when at least a central part of the one-side end (2a) of the corresponding operation key (2) is flush with or projects relative to the strip-like guide surface (8d), and in a deeply depressed state when the one-side end (2a) of the operation key (2) is below the strip-like guide surface (8d).
