PURPOSE: Rigidity reinforcement apparatus for the fastening part of a glass loading cassette is provided to combine a side plate and a rear plate together through a hooking protrusion and a combining protrusion, thereby preventing particles from being generated at a fastening region of the side plate and the rear plate in advance. CONSTITUTION: A cassette is composed of an upper plate(1), a lower plate(2), multiple side plates(3), and multiple rear plates(4). A hooking protrusion(10) with a stair shape is formed at each of the upper plate and lower plate. A combining protrusion(11) corresponding to the hooking protrusion is formed at each of the side plates and rear plates. A combining protrusion(12) is formed at each connection region of the side plates and rear plates. The hooking protrusion and the combining protrusion are fixed with a bolt(9). |
