Abstract
A novel tape cassette which has tape guides that prevent the tape from moving upwardly or downwardly in the cassette and which are constructed by providing interleafed guides which are formed by molding from opposite sides of the top and lower half of the cassette during construction. It has been discovered that the tape guides molded in plastic cassettes tend to incline or tilt away from the front edge of the cassette which result in the tape moving upward or downwardly as it engages such inclined tape guides. The present invention provides for forming a portion of the guides from the upper half of the cassette and other portions of the guides formed from the lower cassette half such that the combination of the upper and lower guides interleaf and result in the tape being maintained in the desired center relationship while traveling in either direction.
