PROBLEM TO BE SOLVED: To deal with customers efficiently without using a large-scale apparatus. SOLUTION: The processor is provided with a first and second input means (for example, a key board 110, a scanner 111, and the like) as a data input means. Commodity sales information based on commodity data inputted by the first input means 110a, 111a, and the like and commodity sales information based on commodity data inputted by the second input means 110b, 111b, and the like are displayed on displays (an operator display 107 and a customer display 120) on the right side and left side respectively, and the commodity sales data processing can be executed right and left independently (dual mode). When the dual mode is set, input of the commodity data by the first input means 110a, 111a, and the like and input of the commodity data by the second input means 110b, 111b, and the like are distinguished by differentiating display modes of the display at the time of commodity data input.
