<p>PURPOSE:To position a tape guide with high accuracy by applying pulling force obliquely downward to a direction, where a guide base is press-contacted through a linking member, to a catcher at a prescribed angle to the surface of a chassis when a prescribed tape path is formed. CONSTITUTION:A loading ring 14 and the guide base 11 are linked through the linking member 15 and as the turn of the ring 14, the base 11 is guided by a guide rail 13, moved in an arrow C direction and engaged with the catcher 4. Then, mounting operation is completed. Since the base 11 is drawn by the linking member 15, the base 11 is guided by the guide rail 13 and moved parallelly with the surface of the chassis 2. When the tape mounting operation is completed, the posture of the base 11 is changed in an inclined direction at a prescribed inclination angle by a guide surface 4-a of the catcher. Afterwards, since a guide base boss 18 is engaged with a V-shaped groove in the upper part of the catcher 4, a horizontally rectangular coordinate position is determined and since a positioning pin 17 of a guide base seat part is engaged with a groove provided on the guide surface 4-a of the catcher, a horizontally rotating direction position is determined.</p> |
