Abstract
Abstract Cassette to cassette duplicating means are provided for reproducing cassette tape copies from a master cassette tape. A master cassette reproducer reproduces a program from a master tape. A modular interconnecting tray is adapted to mount one master reproducer and plurality of slave reproducers. The tray has a plurality of interconnected sockets to receive plugs in the reproducers. Additional trays may be plugged into the first tray to provide additional copies simultaneously.

Total Claims: 5
Claim 1
Independent Claim
97 words
Cassette to cassette duplicating means, comprising, a master casette reproducer for reproducing a program from a master tape, a plurality of slave cassette reproducers to record said program on slave tapes, said master slave and reproducer having plug-in connection means, a tray adapted to mount one master reproducer and a plurality of slave reproducers, said tray having a plurality of interconnected sockets to receive said plug-in connections of said master and said slave reproducers, wherein said reproducers have capstans mounted on ball-bearings and spring means connected to preload the ball-bearings to reduce flutter by preventing radial looseness.
