<p>PURPOSE:To easily insert a tape cartridge to a housing by shifting automatically the door body of the housing immediately after the action of a magnetic tape device is started. CONSTITUTION:A door body 16 is energized in the direction to close the aperture by a spring 17 and at the lower edge of one edge part of the door body 16, an arm 18 to extend in the slanting lower direction is protruded. On the other hand, at a housing driving plate 2 of the position near one side of the leading part, the aperture not shown in the figure is formed, and on a substrate 1 along the inside of the aperture, a bracket 19 is vertically provided. The aperture is largely formed at the circumstance of the bracket 19 so that the bracket 19 cannot restrict the shifting of the housing driving plate 2. At the bracket 19, a lever 20 to extend in the direction of the arm 18 is freely turnably pivoted by a supporting shaft 21 and at the tip of the lever 20, a hook 22 to engage with the tip of the arm 18 is formed.</p> |
