PURPOSE:To arbitrarily control whether an all void processing is executed or not. CONSTITUTION:Various counters 18 store the total values totaled in each separate classification in accordance with a registering operation of sales data. An all void propriety setting memory 19 stores at every classification the control data for showing execution propriety of an all void processing set arbitrarily in advance in accordance with the classification of various counters 18. In such a state, when an all void key BK is operated, a CPU 11 determines the execution propriety of the all voice processing at every classification, based on the control data stored in the all void propriety setting memory 19, and executes the all void processing for returning the total value in various counters 18 corresponding to the executable classification to an original state that there is no registering operation of sales data of a one-transaction portion. |
