Abstract: PURPOSE:To utilize the input board surface more effectively to input many input items, by increasing the number of rows of eyeholes for keys, which are provided on the key mat, more than the number of rows of input keys by one row. CONSTITUTION:The number of rows of eyeholes 5, 5' and 5'' provided on respective key mats 21-216 of code input device 1 is increased more than the number of rows of input keys 6 by one row. This increased row is shown by 5' and 5''. Though eyehole row 5' is unuseful and rest holes 5 are useful on key mat 21, these unuseful holes 5' become useful holes (keys 6 are protruded from these holes) and the hole row in the side edge part out of useful hole rows becomes an unuseful hole row when key mat 21 is turned over to the right. Thus, each time key mats are turned over, the relation between unuseful holes and useful holes is inverted. Further, spaces (a) and (b) are reduced to minimums.
