Abstract: PURPOSE:To prevent the erroneous input of adjacent keys by composing one key by plural number of electrode groups and deciding that the key is ON only when the plural number of electrode elements to be the part are simultaneously are short-circuited. CONSTITUTION:For instance, a key A is composed of the electrode groups composed of 6 electrode elements A11 to A32. At this point, the processings at the time of depressing operations in the vicinity of the boundaries of the key A and a key B, and the key A and a key D are mentioned. In this case, when plural number of the electrode elements A11 to A32 to be the part are simultaneously short-circuited, it is decided that the key A is ON. Namely, when the electrodes A1 n, A2 n (n=1, 2), for instance, are simultaneously tuned ON or A2n, A3n are simultaneously turned ON, it is decided that the key A is selected. In this way, the area from an uppermost location 9a where the key A is made effective to a lower location 9b where the key A is made effective can be made a depressing effective area. Thus, by setting the depressing effective area which is wider than the original keys A to E, the erroneous input of adjacent keys can be prevented.
