Abstract
A cassette autochanger for automatically supplying and selectively reproducing a plurality of cassettes (C) having programs recorded therein comprises a plurality of recording/reproducing devices (3), a plurality of cassette storage locations (5, 6), a cassette transporter (4, 9) for transporting the cassettes (C) between the locations (5, 6) and the devices (3), a first detector (23) for detecting any one of the programs that is recorded in one only of the cassettes (C) , a second detector (23) for detecting two of the devices (3) which are available for use, and a dubbing controller (24) for controlling the two detected devices (3) so that such one of the programs is automatically dubbed on to another cassette (C) using the two detected devices (3). A cassette autochanger system may comprise two cassette autochangers (41A, 41B), the second autochanger (41B) forming a back-up which takes over reproduction using an up-dated reproduction list derived from the first autochanger (41A) in the event of the first autochanger (41A) becoming out of order.
