Abstract
The invention provides a cassette which is sufficiently sturdy even though its side boards are of narrow width, is protected against static charging in the insertion and removal of substrates and, hence, against circuit failure, and is not liable to form a dust of friction. The invention further provides an improved substrate-supporting side board for use in the fabrication of a cassette. The above substrate-supporting side board comprises a metal core, an overlay and a plurality of shelf members, at least the frontal part of the overlay and the shelf members being made of resin, the shelf members being tongue-shaped projections arising from the overlay and extending in parallel and inwardly of the cassette frame at a predetermined pitch with an upward inclination toward free ends thereof, the supporting surface of each shelf member being slightly elevated in the center with respect to its flanks, and at least part of the portion of the resin which is to contact a substrate being molded from a dust-inhibited resin molding material, with the remainder being molded from an electrically conductive resin molding material.
