PROBLEM TO BE SOLVED: To provide a display input device such that there is no structure that hinders operation around a spatial image projected in the space and input operation around the spatial image by using an input member such as a finger of an operator can be naturally performed without minding the device.SOLUTION: A display input device has a configuration in which a panel-form imaging optical element (micro mirror array 1) is disposed on a top face of a housing (case 10), a light source (LED 4) is arranged around the micro mirror array 1 so as to illuminate an input member (finger H and the like) above the housing, a mounting table 2 is arranged at a given position in a lower portion of the housing corresponding to the micro mirror array 1 while being inclined at a given angle α with respect to the micro mirror array 1, and optical detection means (camera 5) is arranged at a position where the input member (finger H and the like) positioned about a spatial image (I') can be detected. |
