BOOK ACCUMULATING SYSTEM

PROBLEM TO BE SOLVED: To provide a checking system for off-line checking. SOLUTION: Bar codes for the bar-coded weight of books corresponding to orders from book stores are read by a bar code reader 6 to cause an comparator to compare electric signals based on the weight read out by the bar code reader 6 with electric signals based on the weight of delivery bundles taken out of a book accumulation part 3 measured by an electronic meter 7 or to cause a memory card to store the weight of books corresponding to orders from book stores and a comparator to compare electric signals based on the weight read out of the memory card by a reader with electric signals based on the weight of delivery bundles taken out of the book accumulation part 3 measured by the electronic meter 7, thereby to check whether the delivery bundles are correctly formed or not.
