PROBLEM TO BE SOLVED: To keep the number of unprocessed orders down.SOLUTION: An order processing unit 2 compares the number of pieces of order data, i.e. transmission objects registered with order information 1a stored in a storage unit 1 with a prescribed threshold value. If the number of pieces of order data registered is equal to or less than the threshold value, the order processing unit 2 selects a first method that issues a transmission request 5a to a communication control unit 3 and processes the next piece of data after the reception of a transmission completion notice 5b. If the number of pieces of order data exceeds the threshold value, the order processing unit 2 selects a second method that issues a transmission request 6a to the communication control unit 3 and processes the next piece of order data after the reception of a reception completion notice 6b.SELECTED DRAWING: Figure 1 |
