An adapter assembly is used to attach a module having a mating interposed portion to an attachment member having a mating fixing portion. The adapter assembly comprises a main member having a fixed portion and an interposed portion, a fixing member, a first interposing member having a first interposing portion and a second interposing member having a rotation stopper and a second interposing portion. When the module is attached to the attachment member, the fixed portion is interposed and fixed between the fixing member and the mating fixing portion, and the mating interposed portion is interposed and held between the interposed portion pressed by the first interposing portion and the second interposing portion. During the attachment process of the module, the rotation stopper prevents the second interposing member from being rotated relative to the module.
