Abstract

A system for providing stable tape-travel in a recording and/or reproducing apparatus includes a tape travel-direction switching mechanism and a tape tension regulating mechanism. The tape travel-direction switching mechanism forces a pendulum gear to engage one of a supply or take-up reel table when the traveling direction of tape is switched between forward and reverse directions while a capstan motor is turned off and a pinch roller presses the tape against the capstan so as to prevent the occurrence of slack in the tape. The tape tension regulating mechanism takes up the slack in the tape before a capstan axle causes the tape to travel in the reverse direction, so as to prevent the tape from being loosened when the traveling direction of the tape is switched from the forward direction to the reverse direction.
