Abstract
Abstract A cabinet for pocket machinery having a transmissive liquid crystal display member. The cabinet includes a first cabinet member for holding the liquid crystal display member and electronic circuitry. The first cabinet member has a cavity at its rear. The liquid crystal display member is coupled to the rear of the first cabinet member within the cavity. A second cabinet member fits within the cavity in the first cabinet member and is removable from the cavity in the first cabinet member. The removal of the second cabinet member from the cavity in the first cabinet member exposes the liquid crystal display member.
