Abstract
A letter sorting machine separates pieces of mail one by one from a stack of various types of mail,reads information such as their postcodes and addresses,then stacks and sorts them according to the reading results.Recently,flat mail items are increasing in domestic and overseas,and the performance requirements for such machines have become increasingly stringent in the global markets.To respond to these requirements,Toshiba has developed a feeding technology that can achieve industry-leading levels of processing speed,employing an air-absorption technique.This technology will facilitate our further expansion into the global markets.
