PURPOSE: To make it possible to reduce a mounting pitch of housings to be stored, to cause the stored housings to be locked in position more perfectly, and to facilitate drawing operations with respect to a structure for arranging a plurality of table-top type small-sized information communication apparatuses in parallel within a shelf and efficiently establishing connections between the apparatuses or between the apparatuses and external lines.
CONSTITUTION: Right side and left side shoulders of a sliding surface 5a of a housing which comes into slidable contact with a guide rail 4 have inclinations which are different from each other. A U-shaped opening 10 is formed at the front end area of the guide rail. A fixed piece is formed on one side wall 4b of that opening, whilst the other side wall is provided with a movable piece 8 which is resiliently de-formable. A lock claw 9 is formed on the end of the movable piece 8. In addition, an engaging protuberance 11 for engaging with the opening when the housing is inserted into a shelf 1 is provided at a position corresponding to the U-shaped opening 10 of the guide rail 4 in the front end area of the slide surface 5a of the housing.
