Abstract: An optical member driving mechanism for connecting an optical member is provided, including a fixed portion and a first adhesive member. The fixed portion includes a first member and a second member, wherein the first member is fixedly connected to the second member via the first adhesive member.

Abstract: A position adjustment mechanism for grinding wheels includes a rotating body, a first grinding unit, a second grinding unit, and a fixing nut. The rotating body includes a fixing surface and a first thread portion. The first grinding unit includes a first grinding portion and a fixing portion fixedly engaged with the fixing surface. The second grinding unit includes a second thread portion, which is threadedly engaged with the first thread portion of the rotating body, and a second grinding portion which is spaced from the first grinding portion and which has a different grinding precision from that of the first grinding portion. The fixing nut is threadedly engaged with the first thread portion, and presses axially against the second grinding unit. Thereby, a rough grinding and a fine grinding can be accomplished together within a grinding process, and adjustment on a spacing between the two grinding wheels becomes easy.

Abstract: A grinding mechanism includes a rotating body, a first grinding wheel, a second grinding wheel, a first fastening means, a second fastening means, and a spacer assembly, a first fastening means passing through the first body portion and fastening into the rotating body, a second grinding wheel including a second body portion and a second grinding portion. The first and the second grinding portions have different diameter from each other, and are spaced from each other axially, and have different grinding precisions. The spacer assembly is interposed between the first grinding wheel and the second grinding wheel. The second fastening means passes through the second body portion and the spacer assembly, and threadedly fastens into the first body portion, so as to press and secure the second body portion and the spacer assembly against and on the first body portion.
