  • Cassette with magnetic tape on two coplanar reels
    Patent number: 5187629
    Abstract: A cassette comprises a housing which accommodates a magnetic tape partly wound on two reel hubs. A main wall of the housing has two openings which are coaxial with the reel hubs to allow the passage of reel spindles of a drive apparatus. The cassette further comprises a slide cover for covering the openings, which slide cover comprises blocking members which can cooperate with the reel hubs to inhibit their rotation. For this purpose the wall with openings has diametrically opposed recesses or cut-outs to allow the blocking members to engage with inner teeth provided in the reel hubs.
