Abstract
A reference plane moving device comprises an attachment section which is movable along a given reference plane, and a balancer which can operate in correspondence with this attachment section, the attachment section including an air intake hole section capable of creating a vacuum condition between the attachment section and the reference plane by sucking air, and compressed air ejecting hole sections capable of creating a high pressure condition between the attachment section and the reference plane by blowing compressed air against the reference plane. By virtue of a combined action of the vacuum and the high pressure conditions thus created, the attachment section can be kept away from the reference plane by a fixed distance while being attracted thereto. The attachment section with an appropriate attachment can be readily moved on the reference plane.
