<p>PURPOSE:To maintain good tape travel with a simple constitution by providing a stopper means and defining the moving directions and vertical and lateral positions of the roller and moving body of a magnetic tape pulling guide means. CONSTITUTION:When a magnetic tape pulling guide means 4 approaches to a stopper 7, the axis 29 of a tape pull-out roller 4a is led into the U groove 34 in the lower part of the stopper. Next, the top face 43a of the protrusion 43 of the means 4 goes underside the bottom of the horizontal face 35 of the recess 38 of the stopper 7 and further the knife-edge from protrusion 43b in the lower part of the protrusion 43 is led in the ravine 42 formed by the tapers 36 and 37 of the recess 38 of the stopper 7. Since the ravine 42 is so inclined that its front part rises with respect to the horizontal face, the protrusion 43 is sandwiched by the horizontal face 35 and tapered ravine 42 of the stopper 7 and in the final the longitudinal, vertical and lateral positions and postures of the means 4 are defined.</p> |
