A loadable/unloadable adapter for a substrate which can simplify the loading and unloading work of the substrate. A substrate 23 is loaded to an loadable/unloadable adapter 13 . The loadable/unloadable adapter 13 is inserted from a window hole 14 of a housing 12 . A handle member 26 swings about a supporting axis 25 . A projected piece 27 moves in accordance with swinging of the handle member 26 . A projected piece 27 causes the loadable/unloadable adapter 13 to move forward on the basis of the so-called principle of a lever. Even when a resistance force works for the forward movement of the loadable/unloadable adapter 13 on the basis of a friction resistance of both front connector 18 and main connector 21 when these connectors are coupled, the forward movement of the loadable/unloadable adapter 13 can be attained only with a comparatively small force.
