<p>PURPOSE:To simplify the constitution by bringing a tension lever to a driving control by interlocking with an operation of a loading slider, and engaging it to a cam part of a mode switching slider in a loading completed state to that a tape tension control can be executed. CONSTITUTION:When a loading ring is driven to be inverted and loading sliders 13, 14 are inverted, a tension bar 24 is turned clockwise roughly against a spring force of a member 31 by the loading slider 14, and its second engaging part 27 is detached from a cam part 29 of a mode switching slider 28. When the loading sliders 13, 14 are reset to an unloading position, the tension lever 24 is reset to its original stop position by the loading slider 14 against a spring force of its spring member 31, and thereafter, its engaging part 26 is detained and controlled by the side part of the loading slider 13. In such a way, it is not required to provide an exclusive driving mechanism as usual, and the mechanism can be simplified and miniaturized.</p> |
