<p>PURPOSE:To prevent pictures from being disturbed without slackenning the tension of a tape at the time of shifting from a backward jog to a forward jog by providing a rotation pawl capable of rotating around a supporting shaft from a first position where the pawl can be engaged with the driving gears of a supplying reel base to a second position where the pawl is not engaged with the gears. CONSTITUTION:A rotation pawl 20 is provided for being capable of rotating around a supporting shaft 21b from the first position where a pawl part 20a can be engaged with the driving gears 19 of the supplying reel base 17 to the second position where the part can not be engaged with the gears. A first energizing means 23 energizes the rotation pawl to the direction of the supporting shaft or to the first position when the rotation pawl 20 is at the first position, to the second position when the pawl is at the second position. A sliding base 21 mounts the rotation pawl and is made to be movable to move to a draw back position where the pawl being at the first position is not engaged with the driving gears 19 and to an operation position where the pawl is engaged with the gears and further, rotates the supporting reel base to the direction of tape-winding without slackenning the tape tension through the rotation pawl by moving from the retreat position to the operation position.</p> |
