Abstract:
An arithmetic processing device includes a menu displaying unit which displays a menu screen for a plurality of arithmetic processings when the predetermined key is operated, each of the arithmetic processings being assigned to one of a plurality of numeric keys; an arithmetic processing unit which, when a numeric key allocated to any one of the arithmetic processings is operated, executes an arithmetic processing corresponding to the operated key; and a display controller which, when a key other than the numeric keys assigned to the arithmetic processings is operated, displays a specific mark.
