部品回動調整機構。An optical component rotation adjustment mechanism in an optical information reading device including a holder on which an optical component is mounted and a base, wherein the position of the rotation center of the optical component is set at a circumference around the optical component. A first curved surface of the holder forming at least a part of the holder and a second curved surface provided on the base and sliding against each other make the optical component immovable in the optical axis direction. Positioning is performed by a plate-like part formed on the holder and a groove-like part provided on the base to slidably hold the plate-like part, and rotational adjustment of the optical component is performed by a plate-like part formed on the holder. The formed first arm and the second arm provided on the base are connected via a spring with an adjustment screw and a nut, and the above-mentioned An optical component rotation adjustment mechanism in an optical information reading device, characterized in that at least one of the contact points between the screw or the nut and the first or second arm portion is in line contact.
