The operation will be described with reference to FIGS. FIG. 4 is a flowchart showing a merchandise item registration process when the merchandise key (5b) is used. For example, when a product key (FIG. 2A) corresponding to the product code 01 is pressed,
The key position code of the product key is taken out and stored in the key position memory (3-5 (A)) (step 4-1).

The key position code has a sequential value according to the arrangement on the keyboard. By adding the head address of the key layout memory 1 to the key position code, the address of the key layout memory corresponding to the key position can be calculated. it can. By this calculation process, the memory address (3-1 (A)) corresponding to the product key position 01 of the key layout 1 is obtained (step 4-2).

The contents (product code) of the memory are read using this memory address (step 4-3) and stored in the product code memory 1 (3-5 (B)) (step 4-4).

Next, the cumulative sales quantity corresponding to the product code is taken out, the current registration quantity is added, and then written and updated in the cumulative sales quantity memory (3-3 (A)) (step 4-5). Next, the current date / time information is obtained from the CKDC 9, and the obtained data is written and updated in the last sales time memory of the corresponding product code (step 4-6).

FIG. 5 is a flowchart showing the key layout change determination process after the registration process of FIG. 4 and the change process in the case of the automatic process. First, it is determined whether the value of the high frequency determination quantity setting (3-4 (A)) is 0 (step 5-1). If 0, the frequency determination is unnecessary and the determination process ends. Next, it is determined whether or not the cumulative quantity of the commodity registered this time exceeds the set value of the high frequency determination quantity (step 5-2). If it does not exceed the set value, it is determined that the key layout changing process is unnecessary, and the process ends. If the set value has been exceeded, the indicator (8-3 (A) in FIG. 8) on the display device is turned on to notify the operator that the currently registered product has a high sales frequency (step 5-). 3). FIG. 8 is a diagram showing an example of the display screen.

Steps 5-4 to 5-7 are processing for selecting an optimum key as a key to be changed. First, the determination method setting of the item having the lowest registration frequency among the products existing on the key layout (3-4)
(B)) is determined (step 5-4), and the processing is performed by the quantity determination method (step 5-5) and the time determination method (step 5-5).

At the same time, the product code memory 2 is displayed on the display device 7.
The product code stored in (3-5 (C)) is displayed. This represents the product code of the key to be assigned in the case of manual, and represents the product code deleted from the key layout by the automatic assignment in the case of automatic (8-2 in FIG. 8).

Next, the operator waits for a key input from the input device of FIG. 2 (step 6-2). If the input key is a numerical input key (5a) (step 6)
-3), the input numerical value is stored in the product code memory 1 (3-5).
(B)) and returns to the key input process again (step 6-4).

If the input key is the product key (5b), the key position is stored in the key position memory (3-5).
(A)), and if it is any other key, the process ends (step 6-5). Key position memory (3
-5 (A)), the position code stored in the key layout memory 1 (3-1) is calculated (step 6-6), and the product code memory 1 (3-5 (B)) is calculated. ) Is stored in the key layout memory 1 (3-1) (step 6).
