FASTENING MEMBER AND FASTENING MECHANISM USING THE SAME

PROBLEM TO BE SOLVED: To fasten a fastened member as an optical component of an image reader with a screw while suppressing the transmission of rotating force to the fastened member during fastening the screw to eliminate the need for readjustment during fastening it and allow easy work. SOLUTION: At the front end of a flat portion of a fastening member 12, a right-angle bent portion 24 is provided which is bent at a right angle. At the other end of the flat portion, an obtuse-angle bent portion 19 is provided which is bent at an obtuse angle. A through-hole 21 for the screw is provided over between the flat portion and the obtuse-angle bent portion. When fastening the fastened member with the screw, the fastening member 12 is held between the screw and the fastened member so that the right-angle bent portion 24 contacts another fixing member. Thus, rotating force is not transmitted to the fastened member during fastening the screw and the fastened member is not moved from an adjustment position, therefore eliminating the need for re-adjustment. The obtuse-angle bent portion 19 can set the screw in a temporarily fastened condition, therefore allowing fine-adjustment. COPYRIGHT: (C)2008,JPO&INPIT
