穴になっている。In Figures 1, 2, and 3, 1 is a document, 2 is a light source, 3 is a CCD, 3a is a CCD board, and 4 is a screw, which is the same as the conventional example shown in Figures 4 and 5. Since the configuration is the same as the configuration, detailed explanation will be omitted. Reference numeral 5 denotes a lens, and a concave portion 5a is provided on the outer periphery. A mount 6 is provided with a groove 6a for slidably holding the lens 5 in parallel with the optical axis. It is held rotatably around the center. As shown in FIG. 3, the leaf spring 7 is engaged with a recess 5a provided in the lens 5 at a circular arc portion 7a formed at the center. Furthermore, the leaf spring 7 has a screw hole 7b for fixing itself to the mount 6 with a screw 4.
However, it is an elongated hole so that it can be rotated around the pin 6b provided on the mount without removing the screw 4.
