[Prior Art] The optical system of the projection system 'which usually includes a lower case body, and the various lens elements are in the lower assembly process of the first assembly process in the manufacturing period, and the upper cover is closed after the preliminary process. However, since the optical path system of the optical machine is usually composed of a plurality of lens elements, in order to achieve a better projection effect, it is necessary to adjust the angle or the miscellaneous components of the money to form a suitable optical path. Each of the mirror members of the optomechanical unit typically fixes the _piece lens to a plurality of _lens adjustments by changing the adjustment elements to change the angle of peeling, mutual _distance, etc. to form a suitable optical path system. As shown in the first figure, the lens-polarizing element 100 mounts a lens on a holding device 101, and a gear 1〇2 is formed on the top of the holding device 101. Before the polarizer element (8) is assembled in the lower part of the optical machine, the gear on the top of the optical device can be directly pushed to adjust the position and angle of the lens, but after the upper cover is folded, the polarizing mirror element 100 is to be The position and angle are adjusted, and the above-mentioned upper cover needs to be repeatedly opened to adjust the deflection angle of the polarizer by the gear 1 〇 2 at the top of the clamping device 101 and the corresponding gear on the upper cover. However, since the adjustment of the polarizer is driven by the top gear, the upper cover of the optical machine must be covered when the polarizer is adjusted, and the optical path system of the optical machine is composed of a plurality of components. Therefore, the polarizer component is initially adjusted. After the 're-adjustment of other components, the upper cover of the optical machine must be opened again. This causes the upper cover of the optical machine to be repeatedly turned on during the adjustment process, which may cause contamination of the lens components and cause product defects. The operation is very inconvenient. SUMMARY OF THE INVENTION It is an object of the present invention to provide a lens adjusting component that does not have to open the upper cover of the optical machine frequently during the lens adjustment process, and does not contaminate the lens component, thereby ensuring product yield. Another object of the present invention is to provide an optical machine which does not need to open the upper cover of the optical machine when adjusting the lens, does not contaminate the lens element, and can ensure product yield.

In order to achieve the above object, the present invention provides an optical machine including an upper cover, a lower case, and a lens winding member assembled between the upper cover and the lower case, the lens adjustment member including a sheet-shaped holder body and a self-lining The body of the piece is adjacent to the extension of the button shape, and the fixing portion of the splicing lens is fixed to the top of the extension portion and the bottom edge and the _ side of the body of the photographic element are arc surfaces, and the arc surfaces are perpendicular The extinction of the axis of the wire is a specific paragraph of the concentric circle of the center. Compared with the prior art, the lens adjusting component of the optical machine of the present invention has a circular arc surface on the side, the bottom side and the top side, so that the bottom edge and the side round fox face can also be used when the upper cover is not covered. The rotation is guided to adjust the angle of the lens without repeatedly opening the upper cover of the optical machine, thereby avoiding the situation that the lens group is contaminated when the upper cover is opened and the product is bad. 6 200842483 [Embodiment] The main improvement of the present invention is a lens adjusting component of a light machine used in a projection system, and the other structure of the optical machine is substantially the same as that of a conventional optical machine, which also includes a lower case and an upper cover, etc. The other structure of the optical machine will not be described in detail, and it will be described first. Referring to the second and third figures, the lens adjusting member i of the present invention comprises a sheet-like frame-shaped holder body 11 and an extending portion 12 extending perpendicularly from the tip end of the holder body n.

When the lens 2 is mounted to the lens holding area 13, the center of the lens holding area 13 is perpendicular to the center of the optical axis of the lens 2. The left and right side edges 17, lg of the sheet-shaped frame-shaped holder body U are formed by arcuate surfaces which are formed at the center of the optical axis from the center of the lens fixing portion 13 toward the both sides. The center of the bottom edge 19 of the sheet-like holder body projects downward from the center of the lens fixing portion 13 to form a circular orphan plane which is also centered on the center of the optical axis. Referring to the two figures and the third item, the extending portion 12 is vertically extended from the top end of the wire body n, and the extending portion 12 includes a connecting portion 121 perpendicular to the holder body n and the self-connecting portion 121 downward. The upper end is slightly bent and extended, and the top surface is a circular orbital adjustment portion 122 of a circular arc surface. The arcuate surface of the adjustment portion m is also centered on the optical axis center of the lens. In this way, the arcuate faces of the side edges 18, the bottom edge, and the top end extension 12 of the lens adjusting member 1 are each a specific segment of the concentric circle centered on the optical axis center of the lens 2.
