There is provided a door for an exterior cover of an apparatus, traveling over a constant trajectory when opened or closed, being lighter and manipulated easier, being capable to be opened and closed safely, and requiring only a smaller working space. This door comprises: a first lid 30 rotatably supported by the apparatus and formed by a plate member 35 and frame members firmly holding the plate member from four sides; a second lid 10 rotatably supported by the first lid 30 and formed by a plastic plate 15 and frame members firmly holding the plastic plate from four sides; a damper 55 supporting the first lid 30 when the door is opened; and a link 53 arranged so that the second lid 10 and the first lid 30 are folded together when the door is opened. Frame members 12 and 14 located at right side end and left side end of the second lid are formed in an arc shape with the central portion projecting toward or away from the apparatus, and it is preferable that the frame members 12 and 14 firmly hold the plastic plate 15 in an arc shape with an electromagnetic wave-proof shield pasted to one surface or the both surfaces thereof. Handles 60 are disposed to the inner and the outer sides of the door. The handles 60 are formed in a ring shape, and as the handles 60 are movable toward inside or outside, the operability of opening and closing may be improved. <IMAGE> |
