A money handling apparatus includes an operation/display unit to display a money count result, and to display a portion or all of a plurality of various operation keys. The display of operation keys is based on the existence or nonexistence of display, contents of display, display-position information, and one or more conditions of display. A setting unit is configured to set the existence or nonexistence of the display for each operation key, while a control unit calculates the display-position information for each operation key, based on one or more conditions of display stored in the memory unit. The control unit also controls the operation/display unit to display the money count result and to display each operation key that is set to be displayed, in the display position and size that is based on the display-position information for the operation key.
