ABSTRACT:
An input apparatus has a selection key for inputting a signal on the basis of an operation, a timer which is reset by an input of a signal from the selection key and which measures a predetermined time period, and a controller for inputting first conditions such as a menu selection on the basis of an input of a signal from the selection key, and for inputting second conditions such as a menu decision on the basis of an output of the timer. The first conditions are input on the basis of an input of a signal from the selection key, so that an operation such as a menu selection is done. When the selection key is not operated for a time period longer than the predetermined time period set in the timer, the second conditions are input, so that an operation such as a menu decision is done.
