Abstract

PURPOSE:To achieve miniaturization and the reduction of cost by eliminating the need for a vacuum source for a vacuum column, by exercising direct interreel control without providing a static pressure air bearing. CONSTITUTION:A tape guide body 15 consists of a parallel arc surface 15a of a radius R2 centering a point C4 at a slight distance from the center C1 of cylinders 5 and 6, an arc surface 15b of a radius R3 centering on a line C3 parallel to a reel axis, and a plane 15c connecting them. To shape the surface of this tape guide body 15 on the cylinder 5 or 6, the tape guide body 15 is made of plastics or metal and then extremely small holes 16 for forming a static pressure air bearing are made in conformity with the extent of tape flotage. Air for the air bearing is supplied from the cylinders 5 and 6.
