Abstract

PURPOSE:To secure smooth running of a magnetic tape, by using a lubricating member which is high in rigidity and elasticity and has two through-holes arranged in the direction of the length and two projected parts installed at the outer side of the holes, respectively. CONSTITUTION:To an almost rectangularly shaped lubricating sheet 64, through- holes 65 and 66 and inclined planes 72 and 73 which strike against projections for controlling location of a cassette half which in not shown in the diagram, are installed. Moreover, projected parts 74 and 75 which are parallel with a line connecting centers of the through-holes 65 and 66 are arranged in such a way that they are projected toward the inner direction. In this way, the inner ring of a reel hub which is not shown in the diagram is placed on the flat part of the lubricating sheet 64 and the outer ring lightly touches the projected parts 74 and 75 guides tapes by using the reel hub at the center. Therefore, tapes are stably wound.
