Abstract

PURPOSE:To prevent injustice of operations and erroneous operations, by inhibiting the operator from correcting specific information, which is input from the recording medium input part, by the keyboard operation until this information is transmitted as transaction data of one business to a terminal control device, etc. CONSTITUTION:If data is input first from a magnetic stripe input part 30, recorded data is set in an item data set buffer 46. Since a transfer control part 31 outputs a signal to an FF 32 simultaneously, the FF32 is reset, and signals disappear on a signal line 73. Under this state, when the data input operation is performed from a keyboard input part 40 and the transfer to a buffer 46 is instructed, a signal is output from an AND gate 33. Consequently, since a transfer control part 45 is not operated, contents of a keyboard input buffer 44 are not transferred to the buffer 46 and become invalid data. Next, if the input part 40 is operated before data is input from the input part 30, this data is transferred to the buffer 46. Under this state, when data is input from the input part 30, data of the input part 30 is transferred to the buffer 46 to updata its contents.
