Tape recorder having an automatic mode switching mechanism

摘要

A tape recorder comprising first and second latch bars respectively having predetermined tape operating functions and a crosspiece member disposed across the latch bars to lock one or both of the latch bars selectively into notches formed in the crosspiece member. These notches have different depths of cut in the lengthwise direction of the crosspiece member. A first and a second abutment member are movably mounted on the crosspiece to cause it to move in response to the detection of a recorded index signal in its lengthwise direction over different strokes depending on the position of the first abutment member relative to the second abutment member. The strokes are so determined that one of the latch bars is unlocked in response to the detection of a first index signal and the other latch bar is unlocked in response to the detection of a subsequent index signal.
