PURPOSE:To avoid a defective contact due to the flow and the stain of a connection terminal and also to avoid to be spoiled the external appearance for an external memory pack, by opening and closing a shutter plate in accordance with the loading and unloading actions of the memory pack. CONSTITUTION:When a memory pack is loaded into a holder 19, a spring 16 is compressed to slide upward a shutter plate 15 to the memory pack. At the same time, a connection pattern 11c and holes 9c at both ends of the pattern 11c which are hitherto covered by the plate 15 are uncovered gradually. When the memory pack reaches the lowest position, the pattern 11c is exposed completely out of a hole 17b of a decorative panel 17. In this case, the hole 9c drilled to a frame is exposed to outside and at the same time a projected part of a connector supporter is put into the hole 9c. Thus the memory pack is fixed. This attains the electrical and mechanical connection of the memory pack. When the memory pack is pulled out, the plate 15 is pushed down by the resetting power of the spring 16. Then holes 17b and 9c are covered again with the plate 15. |
