PURPOSE:To stabilize the tape driving as a whole, by providing a sucking hole to a guide wall to suck a magnetic tape, and forming a fixed loop to give the meandering to the loop. CONSTITUTION:A reproducing head 12 for magnetic tape 9 is provided together with pinch rolls 1 and 2 which feed the tape 9, capstans 3 and 4, a tear-off wall 6 which tears off the tape 9 from capstans 3 and 4, and a guide wall 7 which extend in the direction where the tape 9 is guided and fed. The wall 7 contains a sucking hole 8 for tape 9, and feed devices 10 are provided on the wall surface opposite to the wall 7 to feed the tape 9 in its feeding direction. The tape 9 which is fed with high-speed revolutions of capstans 3 and 4 is sucked 8. Then the tape 9 is sent to the opposite wall surface while forming a loop. When the tip of the loop touches the device 10, the loop moves in its feeding direction and goes repetitively away from the sucking force. |
