<p>PURPOSE:To eliminate an unnatural impression of function selection by making the selection of a second function consecutive to that of a first function in an electronic equipment in which the first and second function is selected by the difference in the depth of depressing a double action key. CONSTITUTION:At the initiating point of time 11 of a shallow depressing of the key, the first function is executed, and in case the key is released from this position, the first function is continuously executed. But, in case the key is depressed deeply, the first function is necessarily set temporarily because said point of time 11 is always passed by, and as the key is farther depressed to a point of time 13, the operation shifts to the second function. In such a way, the attempt to select the second function always invites the selection of the first function. Therefore, the first function is made such as function that there occur no harm even if the second function is executed immediately following the first function. Since the function is executed at the time of depressing the key, an operator has no unnatural impression in the selection of function.</p> |
