    • PROBLEM TO BE SOLVED: To move a door largely in either direction of the left and the right to a case body, and to open the front of the case body by installing a moving mechanism extending over the case body, an intermediate body and the door. SOLUTION: In a moving mechanism 6, one end of a cable body 61 is fixed 64 at the center of the supporter of a case body 1, one pulley 63 is folded in a semicircle and the other end is fastened at the center of the skirt plate of the door 2, and one end is fixed 64 to the supporter, the other pulley 63a is folded in the semicircle and the other end is fastened 65 to a skirt body in another cable body 62. When the door 2 is moved by length S from the case body 1 to the right, the cable body 61 is transferred forcibly to the right while rotating the left pulley 63, an intermediate body 3 is pushed out by the half of S from the case body 1, the door 2 is displaced largely by a pushed-out section, and the opening of the case body 1 is opened. When the door 2 is shifted to the left, another cable body 62 forcibly moves the intermediate body 3 to the left while turning the right pulley 63a, and the right side of the case body 1 can be opened largely.

    • PROBLEM TO BE SOLVED: To provide a door moved in a right-angled direction to an opening part of an art object display case to close the opening part and opening the front of the opening part in the open state. SOLUTION: One end side of a door 4 for closing an opening part of a case body is fitted to the case body by a plurality of two-shaft hinges 5, 6 having rotary shafts at both ends. Two kinds of two-shaft hinges are used as the two- shaft hinges, which are the long-sized two-shaft hinge 5 long in the distance between the rotary shafts, and the short-sized two-shaft hinge 6 short in the distance between the rotary shafts. Rotary shaft support plates provided on one end side of both hinges 5, 6 are fitted to the back face of the door 4, and rotary shaft support plates on the other end side are fitted to the inner side face of the case body. Connecting members between the rotary shafts of both hinges 5, 6 are bent to avoid interference with the opening edge of the case body.
