摘要

The layout of a unit image UP displayed/outputted can be modified by a layout operation using an input device 802. Furthermore, when the layout of the unit image UP is modified, an actual work load corresponding to the layout modification is calculated and displayed/outputted. For this, for example, when modifying a structure of a unit system used in a sales shop, it is possible to easily examine a new layout of the frame unit in advance and easily check the work load for the layout modification in advance. Thus, provided is a data processing device having a structure which can effectively support structure modification of a unit system formed by an arbitrary combination of unit members of two or more types.
