ABSTRACT:
A tape fast-forwarding and rewinding apparatus comprising a rotation driving circuit for driving a motor for rotating a take up or supply reel so that the tape travels at a first fast-forwarding or rewinding speed, or travels at a second fast-forwarding or rewinding speed, the latter speed being faster than the former, a detection circuit for detecting the radii of wound tape respectively on the take-up and supply reels, and a memorizing circuit for memorizing the ratio of the radii of the wound tape detected by the detection circuit, while the tape is travelling at the first fast-forwarding or rewinding speed. A controlling circuit serves for controlling the rotation driving circuit so that the tape travels at the second fast-forwarding or rewinding speed after travelling at the first fast-forwarding and rewinding speed, and for controlling the rotation driving circuit so that the speed of the tape changes to the first fast-forwarding or rewinding speed from the second fast-forwarding or rewinding speed when the aforesaid value of the reciprocal of the radii ratio, when the tape is travelling at the second fast-forwarding or rewinding speed, is equal to the value of the ratio memorized in the memorizing circuit.
