Abstract: A document integrated management apparatus which manages documents, stored in plural databases controlled by different applications, based on linkage of the documents. A linkage information manager manages linkage information of documents stored in the plural databases managed by the different applications or document sets each having one or more documents linked to each other, and a document information manager manages document information on the documents or document sets. When a client designates a document set, a search is performed on the document information and the linkage information, and the client can extract a document linked to the document set. Thus document extraction or search can be performed without consciousness of control applications of the databases holding the respective documents.

Abstract: A lever 22 is pivotally supported on a male connector 21 by bosses 27, and an engagement projection 30 is formed on a lower portion of each of opposite side walls 28 of the lever 22 at a front end portion thereof. The engagement projection 30 is formed on such an area of the side wall 28 of the lever 22 that the amount of movement of the engagement projection 30 in a generally-horizontal direction in accordance with the pivotal movement of the lever is larger than the amount of movement of the other end of the lever in a generally-horizontal direction. Therefore, the amount of engagement of the engagement projection 30 into the engagement groove 35 is large, and therefore even if the lever 22, incompletely engaged in the guide grooves 34, is pivotally moved, the lever 22 can not be pivotally moved further, and hence an uninterrupted movement of the lever 22 will not occur, thereby preventing a half-fitted condition of the male connector 21.
