Abstract
PURPOSE: To enable to agree the image formation plane of the lens system with the photo receiving plane of the solidstate scanning element, by enabling to fix the inside frame of the lens toward arbitrary rotational direction to the outer frame, in the lens system holding member for the reader.
CONSTITUTION: At the circumference of the inner frame 1 of cylindrical shape holding the lens system L, the extenal plane 12 screwing the inner frame 1 with the the external frame 4, and the external circumference plane 13 mated with the external frme 4, are formed. At the external frame 4 fitted to the external holder member 8, the inner circumference plane 14 coupled rotational-free to the external circumference plane 13 of the inner frame 1, and the inner circumference plane 42 having greater diameter than the external circumference plane of the inner frame 1, are formed, and the fixed screw 6 is screwed by providing the screw holes 45 at the external frame 4 at the position of the inner circumference plane 42. Further, after making pint adjustment through the rotation of the external frame 4, the inner frame 1 is revolved around the light axis to cancell the slope angle orthogonal to the light axis, and after the end of adjustment, the fixed screw 6 is tightened to fix the inside frame 1 to the external frame 4.
