ABSTRACT:
A tape running device for storing and running an endless magnetic tape for mass-producing copies of the endless magnetic tape. The tape running device comprises a tape storage mechanism for storing a long, endless magnetic tape along a zigzag path formed by a plurality of movable guide rollers, a tension control mechanism for maintaining tension in the endless magnetic tape stored in the tape storage mechanism at a predetermined tension level, and tape driving apparatus for driving the endless magnetic tape stored in the tape storage mechanism. The total length of the zigzag path along which the endless magnetic tape is extended in the tape storage mechanism can be varied by properly shifting the plurality of guide rollers so that the tension in the endless magnetic tape is maintained on a predetermined tension level while the endless magnetic tape is being driven. Accordingly, the tape running device is capable of storing an endless magnetic tape at a predetermined tension and capable of driving the endless magnetic tape without turning the tape over and without creasing the endless magnetic tape regardless of the length of the endless magnetic tape.
