Abstract
Abstract A substrate support module (10) includes a series of vertically arranged guide shelves (12, 14 and 16) having front, intermediate and rear circular bosses (34, 36 and 38) projecting from opposite ends thereof. The first and third bosses (34 and 38) are tangentially received in elongated horizontal slots (40 and 44) in side support plates (18) to position and lock the shelves (12, 14 and 16) against vertical movement. The intermediate bosses (36) are tangentially received in vertical elongated slots (42)in the side support plates (18) to position and lock the shelves (12, 14 and 16) against horizontal movement. During assembly, edges of the slots (40, 42 and 44) tend to flatten or shave off small peripheral portions (50) of the bosses when the bosses are slightly oversize, whereby the oversize bosses can readily be assembled into the slots. Backplane assemblies (22) also are mounted on rear edges of the guide shelves (12, 14 and 16) in the same manner by circular bosses (52 and 58) and elongated slots (54 and 60).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
A substrate support module, which comprises: at least one essentially planar guide shelf having guide means for guiding an edge of a substrate when the substrate is inserted into the substrate support module; a pair of side support members located adjacent respective opposite ends of the guide shelf for supporting the shelf; a series of at least three locating projections extending from at least one end of the guide shelf for mounting the shelf on the side support member which is adjacent the one end of the shelf; and the side support member adjacent the one end of the guide shelf having a set of at least three spaced elongated locating slots formed therein, the projections on the guide shelf being received in respective ones of the elongated slots in closely spaced relationship by opposed walls of the slots and in spaced relationship to opposite ends of the slots, with two of elongated slots extending parallel to the guide shelf and the remaining slot extending perpendicular to the guide shelf.
Claim 2
Dependent Claim
170 words
A substrate support module, which comprises: at least one essentially planar guide shelf having guide means for guiding an edge of a substrate when the substrate is inserted into the substrate support module; a pair of side support members located adjacent respective opposite ends of the guide shelf for supporting the shelf; a series of at least three locating projections extending from at least one end of the guide shelf for mounting the shelf on the side support member which is adjacent the one end of the shelf; and the side support member adjacent the one end of the guide shelf having a set of at least three spaced elongated locating slots formed therein, the projections on the guide shelf being received in respective ones of the elongated slots in closely spaced relationship by opposed walls of the slots and in spaced relationship to opposite ends of the slots, with two of elongated slots extending parallel to the guide shelf and the remaining slot extending perpendicular to the guide shelf.
Claim 3
Dependent Claim
34 words
The substrate support module as recited in claim 1, in which: the elongated slot which extends perpendicular to the guide shelf is located intermediate the elongated slots which extend parallel to the guide shelf.
Claim 4
Dependent Claim
23 words
The substrate support module as recited in claim 1, in which: the projections on the end of the guide shelf are circular bosses.
Claim 5
Dependent Claim
