PURPOSE:To simplify the operation of keys and to shorten the time of operation by supplying the information to be selected among those fed and indicating the selected information to perform a collective operation. CONSTITUTION:For instance the articles of the 1st department are all discounted by 10% among those articles registered to a cash register. In such a case, a collective processing key is operated at the first and end of operation. Thus the articles belonging to the 1st department which are stored in a fubber 10 are retrieved to discount all articles of the 1st department by 10%. While the articles of the 2nd department registered to a cash register are all corrected. For this purpose, the collective processing key is operated and then a department key is operated. Then a correction key and then the collective processing key are operated again. Thus the conditions can be decided for retrieval and collective processing based on the procedure of operations with the collective processing key. |
