Casing for electronic device and projector having this casing for electronic device

Abstract

Provided are a casing for electronic device and a projector. The 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, has its part cut out in the circumferential direction and is formed within a range of not overlapping on the circumference of the hole as viewed from the direction of moving forward and backward 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.

Description

technical field [0001] The present invention relates to a housing for electronic equipment provided with a housing main body for accommodating electronic equipment and a leg portion configured to be capable of The inclination of the above-mentioned electronic equipment is adjusted when it enters and exits from the main body surface of the housing and is installed on the installation surface. Background technique [0002] Conventionally, projectors have been used for demonstration occasions such as conferences, societies, and exhibitions, and for viewing movies at home. This type of projector forms an optical image by modulating a light beam emitted from a light source provided in an outer casing according to image information, and enlarges and projects the optical image. [0003] Such a projector is known as a projector provided with a leg portion for adjusting the inclination in order to properly project an optical image on a screen or the like (for example, refer to Paten...

AI Technical Summary

Problems solved by technology

[0005] However, in the leg portion structure described in the above-mentioned Patent Document 1, when molding the frame body by injection molding or the like, the nut must be insert-molded, which may complicate the frame body molding process.

[0006] In addition, due to the simple threaded connection of bolts and nuts, it is possible for the user to store the projector with the inclination adjustment legs screwed into the innermost state.

Therefore, when using it next time, it is necessary to adjust the amount of protrusion again due to the relationship with the fixed leg portion, and there is inconvenience in the use of the projector.

[0007] Furthermore, after the projector is manufactured, when it is packaged and shipped, it is necessary to match the pads and the like to the legs for tilt adjustment, and to match the protrusion of the fixed legs so that the inside does not shake and become unstable. , so there is a problem of time-consuming packaging operations
