PURPOSE:To make the recovery processing for data in course of saving possible, by adding a control number to each data to be saved and adding a control number of the latest pertinent processing data to input data. CONSTITUTION:When a table TBL is restored, a recovery controller RCC2 reads out data including input data, a control number, and POS terminal address, which are logged last, from a logging file F2 and supplies the control number to a comparing part CM. A read controlling part RC reads out a control number corresponding to data of a pertinent POS terminal from an expanded table TBL and supplies it to the comparing part CM. The comparing part CM compares both control numbers with each other; and if the control number from the table TBL is larger than the control number of logging data, POS terminal address data and input data are set to a register REG, and a totalizing processing part CR is started to add these data to pertinent totalized data. |
