Case No. 93100267 V. Description of the Invention (1) (I) Technical Field of the Invention The present invention relates to an optical element group, particularly a balanced optical element group of a balance region. 〃 ^ (2), [Prior Art] μΪΪ来 'advanced with the advancement of technology' The application of optical components is constantly being improved, and these optical components include changes in the wavefront of light behavior (such as gratings - Grating), path transition (eg mirror-Mirror, 稜鏡-Prism, beam splitter-BS 〇r pBS), color selection (eg color filter -Fi Iter), polarization state selection (eg polarizer one)

Polarizer, Waver-Retarder, etc. The following is represented by an optical component applied to a bar code scanner, such as a polygon mirr〇r, a color wheel (c〇1〇r wheel), or a color drum (c〇i〇r drum) to A description of the related art of such optical components. Bar code can indicate the country of manufacture, manufacturer, product name, date of manufacture, book classification number, start and end of mail, category, date and other information'. Therefore, it has been widely used in the fields of commodity circulation, book management and bank account system. application. The Bar code scanner is composed of a light source, optical scanning, optical receiving, photoelectric conversion, signal amplification, shaping, quantization and decoding. Among them, the rotating cymbal is one of the most important optical components in the optical scanning part, and the single beam of light emitted by the light source can be split after being rotated to form a multi-directional scanning light to carry out the barcode on the article ( Scan of Bar code). Then, due to objects of different colors,

IHIH1I Page 5

α When the light source of the scanner is emitted and the black and white bar code is irradiated onto the photoelectric converter, the corresponding digits of the black and the strip are different, and the digits and character information of the reflection, amplification, shaping, quantification and solution are different. Through the processing and management, the wavelength of visible light reflected by the barcode is different. When the light is split to form a scanning beam, the reflected light is focused by the convex lens and then received by the photoelectric converter and the white strip and the light ##. After the circuit is transcoded, the bar symbol can be replaced by the corresponding process of the corresponding circuit to the computer system for data interpretation. • No, a conventional multi-angle plane mirror set in a conventional barcode scanner, a motor 11, a polygon mirror 12, and a cover sheet 13. The cymbal 13 and the polygonal plane mirror 12 are fixed to the motor 11, and the motor 11j is composed of a motor body 111 and a shaft cover 11 2 . In addition, the plane mirror group 1 may further include a positioning member 14 and a row of wires 15 which are separated by a cable 15 and a driver (not shown). The motor body 111 is driven, and the rotation speed of the motor that rotates the optical element is generally centered on the point where the positioning member 14 and the motor body 1 1 1 are axially arranged (the axis of the shaft), and is higher than 720 0 rpm. minute. Therefore, when the center of rotation deviates from the axis of the shaft, that is, when the center of rotation is not on the axis of the shaft, it is easy to cause vibration of the optical element and the occurrence of "Sansheng", which also affects operational reliability. However, there are two main methods for the adjustment of the rotational balance of the rotary optical element. The first type is to directly apply an adhesive on the motor or the cover sheet, which is easy to cause interference of the mechanism or the optical path; the second type is directly Drilling holes in the cover sheet, adjusting the center of rotation by reducing the weight of the cover sheet, so that the optical element

Case No. 93100267 V. Inventive Note (4) When the weight of the weight-fitted material in the balance area of the weight code is not drilled, the weight is placed on the center of the correction optics. In the balance area of the weight, it is also affected by the collision or displacement. Furthermore, by placing the weight on the center of rotation of the element, the generation of optical element noise can be solved, and the optical element is further increased. Compared with the conventional technique, the side wall of the weight area of the present invention can also be stoned. The method is easy to remove, so it can be easily positioned. In addition, it can be avoided that the convexity of the carrier member can reduce the centrifugal force for correcting the vibration of the optical component in the code balance region of the weight, and reduce the reliability of the rotation.
