<p>PURPOSE:To smoothly execute the high-speed inverse traveling of a tape by operating a sub-slider by means of a main slider sliding by a cam, and operating a tension lever by means of this sub-slider. CONSTITUTION:When the cam 2 further rotates clockwise, a first protrusion 51 on the cam 2 goes across a rocking lever 53 on the sub-slider 4 and comes off, so that the sub-slider 4 slides in the direction of arrow D by a spring 45 to energize the tension lever counterclockwise again against a first spring 13 and to hold it in a waiting position. The tension lever thus is separated from a tape T. In the case of the inverse rotation reproduction operation, the operation is executed after the completion of the loading of the tape T, hence the tension lever is not brought into contact with the tape T, therefore, the high- speed inverse traveling of the tape T can be smoothly executed.</p> |
