The third (2l) is a diagram showing the structure of PLU (price lookup) information stored in the memory 2.The PLU code attached to each transaction product is in the PLU code area 2
1, and information representing the product name is stored in the text order area 22. Transaction product ㅅ) The unit price is stored in the unit price field 23, and in this embodiment, two types of unit prices are set. That is, the unit price P2 is set in the region 23a, and the unit price P2 is set in the region 23b.

Specified information that specifies the unit price determination procedure is specified information header 2.
It is set to 4. This designation information specifies a designation code, which will be described later. Further, the total sales quantity of the traded products is stored in the quantity robust area 25, and the total sales amount of the traded products is stored in the sales total area 26. The same number of such PLU information as the number of product keys 12 is set. FIG. 4 is a diagram showing an example of the structure of information stored in the memory 2 and representing the unit price determination procedure. If the designation information is, for example, an 8-bit code, 256 types of procedures can be set. Unit price determination. 7) The designation code scaled by f for each procedure is stored in the designation code area 31. The unit price determination procedure is based on the standard unit rtJ subarea 35 and the condition judgment unit 38.
It consists of three calculation units. In the standard unit price area 35,
Information specifying the standard unit price of traded products is set,
When the truth value of the condition determination unit 38 is "false", that is, when the condition is not satisfied, the unit price specified by this information is used as the unit price of the traded product.

The condition determination unit 38 is composed of a type code area 36 and determination condition head areas 37a and 37b. A type code representing the type of judgment criterion f'+ is set in the type code area 36, and specific judgment conditions are set in judgment condition areas 37a and 37b. In this embodiment, two types of publication regulations f'1; are set. When the truth value of the condition determination unit 38 is “true”,
That is, when the conditions are met, the calculations specified by the three calculation units are performed, and the calculation results are used as the unit price of the traded product.

The three calculation units have an operation code head area 32 and an operand number area 3.
