Abstract
A tape draw-out mechanism comprises a tape draw-out member to be engaged with a tape between a pair of reels and tape draw-out member driving means for reciprocating the tape draw-out member between an initial position and a tape drawn-out position and driving the tape draw-out member so that the return time required for returning the tape draw-out member to the initial position from the tape drawn-out position is shorter than the time required for moving the tape draw-out member to the tape drawn-out position from the initial position. Drawing-out and return of the tape are performed by the reciprocating movement of the tape draw-out member.
Claims15
A tape draw-out mechanism comprising a tape drawout member for engaging a tape in a cassette between a pair of reels and for drawing said tape out of said cassette into a recording-playback position and for returning said tape to said cassette, driving means for driving said tape draw-out member between an initial position in said cassette in engagement with said tape to a tape drawn-out position for recording-playback and for returning said tape to said cassette, said driving means including motor means and linkage means between said motor means and said tape draw-out member, said linkage means including means for returning said tape draw-out member to the initial position in said cassette from said tape recording-playback position in a time shorter than the time required for moving said tape from said position in said cassette to said recording-playback position.
A tape draw-out mechanism comprising a tape draw-out member to be engaged with a tape between a pair of reels and tape draw-out member driving means for reciprocating said tape draw-out member between the initial position and the tape drawn-out position and driving said tape draw-out member so that the return time required for returning said tape draw-out member to the initial position from the tape draw-out position is shorter than the time required for moving said tape draw-out member to the tape drawn-out position from the initial position, wherein draw-out and return of the tape are performed by the reciprocating movement of said tape draw-out member, said tape draw-out member comprising an arm having a tape engaging portion on one end and a fulcrum on the other end, said arm being turned with the fulcrum as the center of rotation by said driving means, said arm having a link groove, said driving means having a crank member having one end slidably engaged with said link groove and rotating with a shaft thereof as the center of rotation and a driving source for driving said crank member with said shaft as the center of rotation, and rotation of the driving source is converted to a swinging motion of said arm.
