WORK PIECE CONTAINING RACK

PURPOSE:To improve assembling accuracy by constituting a container rack having a plurality of container sections of an outer frame and vertical partition plates with slits incorporated in the frame and horizontal partition plates with slits meshed the slits of the former slits. CONSTITUTION:A card containing rack 1, for example, comprises an outer frame 26 as a base body and vertical partition plates 27 and horizontal partition plates 28 incorporated in the outer frame 26 so as to form many container sections in cell construction. At the back edges of these vertical partition plates 27, slits 29 are formed at a specified pitch. On the other hand, at the front edges of the horizontal partition plates 28, supporting sections 31 are protruded at a specified pitch, and slits 32 to be meshed with the slits 29 are formed on the supporting sections 31. In addition, at the heads of the supporting sections 31, burrs 33 for preventing cassettes from coming off are formed. The vertical and horizontal partition plates 27 and 28 are connected to each other so as to be reinforced by meshing the slits 29 and 32. This constitution serves to improve assembling accuracy.
