ABSTRACT:
The invention relates to a recording- or reproducing apparatus for a strip-type information carrier having different operating modes and comprising an intermittent drive mechanism including a cam device rotatable about at least one axis. A carrier is movable relative to the cam device and has at least two positions corresponding to different operating modes; at least two cam followers are provided for engagement with the cam device. The cam followers are arranged in spaced relation on the carrier, each cam follower having an operative and at least one inoperative position in dependence on the position of the carrier. The respective cam follower transmits movement from the cam device for the intermittent drive of the information carrier only in its operative position. The apparatus further comprises a mode control device which is operatively connected to the carrier and controls the positions thereof.
