CONSTITUTION:An operational key 11 has a display device with operational key 3a an its upper face and, when pressed down, it is moved downward. A switch part 12 holds the operational key 11 and is provided with a press-dawn sensor which senses that the display device with operational key 3a was pressed dawn, a transferring means which transfers required information such as characters, etc., to the device 3a, etc. Here, eight pairs of the elements of the operational key 11 and a switch part 12 are arrayed as an example. A small gap 3b is provided between respective display devices with operational key 3a for recognizing a border with touch. |
