<P>PROBLEM TO BE SOLVED: To provide a touch type keyboard which is convenient in operation and novel in exterior appearance. <P>SOLUTION: A touch type keyboard includes a touch plate, a board, a projection device, and a control module. The touch plate covers the board and the projection device is arranged on the board so as to be raisable. The control module is concatenated to the touch plate and previously stores coordinate information of a plurality of key icons inside. The projection device includes a projector to project the key icons on the touch plate. When the key icon projected on the touch plate is touched, the control module detects a touched position and records the coordinate information of the touched position. Then, the coordinate information is compared with previously stored coordinate range information of the key icons, so as to output command information corresponding to the touched position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
