发明名称 Resilient protrusion for positioning in a spool of a magnetic tape cassette
摘要 A video cassette consists of an upper cassette part (8) and a lower cassette part (6), at least one reel which is located therein and onto which magnetic tape can be wound, in which a pressing spring resiliently loads the tape reels (1, 2) in the direction of a defined operating position, the hub (3) of the tape reels having on its side facing the upper cassette part a centrally arranged sleeve-shaped recess (11). According to the invention, there is seated in the recess a helical spring (10), which is resiliently supported in the recess and in the other end of which there is fitted a pin (12), which consists of abrasion-resistant material and the upper end (7) of which bears against the upper cassette part (8) in the assembled cassette state (FIG. 2).
