PITCH CHANGE DEVICE AND PITCH CHANGE METHOD

摘要

A pitch conversion device and pitch conversion method is directed to convert the pitch of a plurality of partition members arranged parallel to each other along an X-direction and include a plurality of entry members arranged parallel to each other in the X-direction and configured to enter between neighboring partition members, and a pushing member to push the plurality of entry members in turn and allow them to enter neighboring partition members while moving in the X direction. The entry members are biased in an exiting direction from between the neighboring partition members.
