<p>PURPOSE:To freely select a state possible to perform recording, and the state to prohibit the recording, by providing the deep state and the shallow state of a position where a flat plate is fixed at a recessed part, and enabling the recording of a cassette tape to be performed in the state on one side, and prohibiting it in the state on the other side. CONSTITUTION:When the flat plate 1 is pressed in a direction of arrow head (a), it advances with a movable member 3 compressing a spring 2, and a pin 3a at the tip of the plate passes through a guide groove 5, and advances along the inclined surface 4a of a fixed member 4, and is connected at a point (c) on the recessed part 6 of the fixed member 4. At this time, a mis-erasure preventing function is performed. And when the flat plate 1 is pressed again in the direction of arrow head (a), the pin 3a is moved from the point (c) of the fixed member 4 in a direction of arrow head (d), and the spring 2 which deviates the flat plate 1 is stretched, then the flat plate 1 is returned to its original position. Thus, by providing the flat plate possible to be displaced at the recessed part of a mis-erasure preventing part for a magnetic recording and reproducing cassette tape, it is possible to select arbitrarily the state possible to perform the recording, and the state to prohibit the recording.</p> |
