    摘要： A double-tape pedestrian traffic control device including a hollow, one piece post having an open upper end, and at least one slot in the post about midway between its ends. A first cassette is mounted on the upper end of the post and a second cassette is located within the post at the level of the slot. Each cassette contains a tape wound on a spool, the spool being spring-biased to rotate in a direction which winds the tape on to the spool. The tape of each cassette is extendable from that cassette in a direction generally perpendicular to the vertical axis of the post, the tape of the second cassette extending through the slot in the post. The diameter of the second cassette, along its entire axial length, is smaller than the internal diameter of the post, so that the second cassette can be inserted into the open upper end of the post and moved to its location between the ends of the post. The second cassette is furnished with means for maintaining tension in the retractor spring prior to and during insertion of the second cassette into the post, the tension-maintaining means being positioned substantially within the confines of the outer dimension of the second cassette, so as not to interfere with insertion of the second cassette into the post. After the free end of the tape of the second cassette is manipulated outwardly through the slot in the post, a pull is attached to the free end of the tape, the pull being too large to fit through the slot and hence preventing full retraction of the tape into the cassette.
