Total Claims: 2
Claim 1
Independent Claim 264 words
A tape feeder in a tape recorder comprising: a pair of reel support drive gears mounted on a pair of reel supports; a pair of tape winding gears capable of being brought into or out of mesh with the corresponding reel support drive gears; a pair of capstans driven by a motor for rotating the corresponding tape winding gears; a pair of pinch rollers connected to a head base plate and capable of being brought into and out of pressing engagement with the corresponding capstans; a pair of reverse action members rotatably supported on the corresponding capstan bearing, said reverse action members having the tape winding gear rotatably supported at one end thereof and having a cam groove formed at the other end thereof, said cam groove being adapted for receiving the shaft of the pinch roller to bring the pinch roller into or out of pressing contact with the capstan; a pair of springs provided to the corresponding reverse action members, said springs being adapted to press the pinch roller against the capstan when the head base plate advances and at the same time urge the tape winding gear to mesh with the reel support drive gear; and a slider member slidably provided between the pair of reverse action members, said slider member being slid, when the tape winding is completed, toward the reverse action member on that side where the tape has been wound so as to push one end of that reverse action member against the force of the spring and at the same time release the other reverse action member.
