ABSTRACT:
An automatic stopping device for a tape feeding apparatus which can assuredly detect that a tape is wound to its last end and can stop feeding of the tape not only in a reproduction mode but also in a fast feeding mode of the tape feeding apparatus. Stopping of rotation of a reel shaft is detected by a frictionally cooperating cam follower which is thereupon disengaged from a circular cam and engaged with an operating element both on a turning force transmitting member to pivot a pivotal member so that the turning force transmitting member on the pivotal member is moved out of a turning force transmitting route from a capstan shaft to the reel shaft and a switch is operated to deenergize a motor connected to the capstan shaft. After stopping of the motor, a movable member may be manually moved to a rest mode position in which the cam follower is engaged with the circular cam again. The movable member is arrested at the rest mode position until a tape cassette is subsequently loaded in position in the tape feeding apparatus.
