A data input device comprises a microprocessor electrically connected to a camera device, a mirror installed in front of a lens of the camera device to allow the camera device to take a reference image reflected by the mirror. When the microprocessor detects that the camera device takes that a user touches the reference image in at least one input zone of an image, it then generates a corresponding input signal according to that the camera device takes that the user touches input images in at least one input zone. The data input device according to the present invention can more accurately and quickly generate input signal corresponding to an input operation processed by the user and saves the production cost more.
