Observe operation principle again as Fig. 7 b example illustrated.The front end face (50 ') of casing (50) is fixed with magnetic part (130), hold the hatch door handle (112) of check hatch door (110) when both hands, when being affixed to check hatch (104) the place ahead, because magnetic part (130) absorption check hatch door (110), check hatch door (110) then are attached to the front end face (50 ') of casing (50) and open and close check hatch (104).
In addition, if will separate down at the state that check hatch door (110) is attached at casing front end face (50 ') when checking hatch door (110), the hatch door handle (112) that both hands are held both sides, the front formation of check hatch door (110) draws forward, and check hatch door (110) then separates from casing (50) and unlatching check hatch (104).
That is, when the user applies greater than magnetic part (130) to the active force of check hatch door (110) absorption and draw the check hatch door when (110) forward, check hatch door (110) just can break away from from the front end face (50 ') of casing and be dismantled.
As above the present invention of structure is not confined to this example, in its technical scope, is that various deformation can be carried out in the basis with the present invention.
For example, first example of this example (Fig. 7 a) in, moving guide rail (120) is arranged to left and right directions, makes check hatch door (110) move left and right and opens and closes check hatch (104).If moving guide rail (120) is arranged to above-below direction, makes check hatch door (110) move up and down and open and close and check hatch (104) also harmless.
