Abstract: The invention is related to a fixture device for motherboard module by placing two fixing plates on the locational surface of a major control device. A Π-shaped slide way with the same width as the motherboard module is formed on the base plate below the fixing plate. Additionally, a locating button in front of the opening of the slide way is used to secure the motherboard module into the slide way. Through this approach, the motherboard module can be easily installed/disassembled by pressing the locating button without using any tools or test fixtures.

Abstract: The present invention relates to an adjustable height apparatus applied to a horizontal projector and comprises a shield assembly, a supporting means, a compression link and a lever. When adjusting the projection elevation, an external force is applied on an adjusting button of the top wall of the projector. The compression link, connecting with the button, makes a vertical movement according to the external force and pushes the detent of the lever to depart from contact with the axial height-positioning component. The sleeve extends toward the outside of said shell by the elasticity of a first elastic component for adjusting a suitable height of the bottom base of the supporting means of the projector.

Abstract: An open-closed structure is used to open or close a lamp door of a projector. The projector includes a main lid. The lamp door covers the outer side of the main lid. The open-closed structure includes a base and a knob. The base is disposed at the inner side of the main lid. The knob is rotatably disposed on the base, and has an axial portion, a hook portion and a stick-like portion. One end of the hook portion is connected to the axial portion, and another end of that is selectively engaged with or separated from the lamp door. One end of the stick-like portion is also connected to the axial portion. When the axial portion of the knob is rotated to make the another end of the hook portion separated from the lamp door, another end of the stick-like portion is dependently moved to push the lamp door.

Abstract: An adjusting apparatus for projection comprises a carrier having a central screw hole and three rounded indentations around central screw hole, an adjusting frame having a plane section and a base section, and a holder. The center of the plane section has a circular concave dug a hole with a smaller aperture. A ball bearing is accommodated in the circular concave. The plane section of the adjusting frame has three screw holes corresponding to the rounded indentations. Three angle-adjusting bolts respectively insert through the screw holes to abut against the rounded indentations. Rotating the angle-adjusting bolts relative to each other varies the length of the angle-adjusting bolts calculated from the plane section of the adjusting frame to the carrier. Thereby, an angle adjustment of a mirror is achieved.
