    摘要: A casing for electronic device having a casing body for housing an electronic device and a foot part provided to be movable forward to and backward from a surface of the casing body and adapted to adjust inclination of the electronic device, the casing body has a boss that is formed to protrude on the inner surface of the casing body and in which a hole connecting the inside and outside of the casing body is formed, and the foot part has a grounding part exposed from the casing for an electronic device and abutted against an installation target surface and a shaft part housed within the boss and having a screw groove formed on its outer circumferential surface. A recess part is formed at a part of the screw groove of the shaft part, and on the inner surface of the boss, a screw thread that engages with the screw groove of the shaft part and extends in a circumferential direction of engagement without overlapping a circumference of the hole as viewed from the axial direction of movement of the foot part, and a protrusion that fits in the recess part when the shaft part turns by a predetermined quantity in relation to the inner surface of the boss, are formed.

    摘要: A virtual screen display apparatus includes a display arranged to generate display information and having an effective diagonal length DLC and an optical projecting element arranged to receive the display information from the display and to project and form an image, the optical projecting element having an effective F number which is defined by Fe=S1/PuD wherein S1 is a distance between the display and a principal point of the optical projecting element and PuD is a diameter of an exit pupil of the optical projecting element. A field optical element arranged to form an in-space image in a position of a virtual screen and to direct a divergent light flux from the virtual screen to a view region where the image is viewable to an observer. A diameter of a range in which the image is viewable to the observer in the view region is ERD and a diagonal length of the virtual screen is VSD and a distance between the virtual screen and the view region is VSP, and the following equation is satisfied: VSD/VSP=DLC/(ERD×Fe).
