Abstract
To provide a fingertip tactile-sense input device in an input device having a plurality of keys within an extremely small range such as within a range of person's fingertip movement, which while being made extremely small and thin, enables key input while maintaining a sufficient click feeling, and also which is excellent for mass production. A base plate (50) has one dome spring (51) arranged at an approximate center of a side of a hole space, and a contact structure (52) on an inside of the dome spring (51). A surface sheet (20) is fixed to a flange (11) so that in a free state, this becomes approximately the same level as an other face of a frame (10), and is provided with a plurality of surface protrusions (21) deployed within a range in which the person's fingertip moves, and has flexibility, elasticity, and pliability. A digitizer (30) is arranged on the hole space side of the surface sheet (20), so as to be slidable on the surface sheet (20), and is capable of electrically measuring a position where a force applied to the surface sheet (20) is the strongest. A convex part (41) is provided on an actuator (40), and the actuator (40) is fixed to the digitizer (30), and has rigidity.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
