PURPOSE:To rationalize the totalizing work and to prevent an error of accounts, by providing a room memory consisting of a main part which totalizes the credit sales data for each room of a restaurant and a chain part which records the redit sales data for each room and each restaurant. CONSTITUTION:A data processing memory 2, a room memory 3, a channel control part 4, an on-line control part 5 and a flexible disk control part 6 are connected to a CPU 1. The memory 3 consitsts of a main part which totalizes the credit sales data for each room and a chain part which records the credit sales data for each room and restaurant in response to the chain address of the main part. The credit sales generated at each register is received at a channel control part 4 and then totalized to the memory 2 by a command of the CPU 1 and at the same time stored in the memory 3. In such a way, the credit sales data generated at registers are recorded accurately for each room and restaurant. Thus, eliminates the generation of an error of accounts. |
