SCREEN DISPLAY KEY INPUT UNIT

摘要

A screen display key input unit in which any one of keys (21 to 35) shown on a screen (3) is inputted by touching with a pen (15), a mouse or the like. Each of the keys (21 to 35) shown on the screen (3) are defined with the first and second graphic character codes. A key input means for pointing out in a key display area on the screen (3) and a selection processing means for outputting one of the first and second graphic character codes defined on each of the keys (21 to 35) by determining the difference of key selection operations of the key input means are provided. The two graphic character codes are defined on each of the keys (21 to 35), so that the number of keys shown on the screen (3) is reduced as compared with a conventional input unit which each key is defined with one graphic character code, resulting in the improved operability.
