摘要： From an optical disc drive, internal static electricity has to be discharged to the outside to prevent breakage of electric components such as laser diodes. A grounding spring has been used to discharge static electricity from a unit mechanism to the enclosure of the optical disc drive but it is necessary to improve the reliability of the drive in consideration of the dimensional accuracy and workability of the spring. Thus the free end of a grounding spring having a cantilever structure is shaped like an arc and an end of the grounding spring has a curved structure. This configuration improves the dimensional accuracy and workability of the spring, so that the performance of the optical disc drive can be more reliable.

摘要： Since a disc vibrates in a natural mode at a predetermined rotation speed, a variation in a tilt of the disc relative to an optical head is caused. As a result, the read/write performance of a disc drive is deteriorated. The disc drive has a disc tilt database for recording a relative tilt angle of the disc in a tangential direction thereof associated with the disc natural mode and the disc rotation speed at which such tilt occurs, a circuit for detecting a disc rotation speed, and a tilt drive circuit. An objective lens is tilted so that the relative tilt angle is corrected, and thus, stable read/write performance of the disc drive is achieved.

摘要： Guide members for guiding an optical pickup for movement in directions parallel to a diameter of an optical disk relative to the optical disk are formed of a metal, support members supporting the guide members on a chassis are formed of a resin, and heat transfer members formed of a metal are set in contact with the guide members and the chassis to achieve both the dissipation of heat generated by the optical pickup and the isolation of the optical pickup from vibrations. The guide support members attenuate vibrations propagating from the chassis toward the optical pickup, and heat generated by the optical pickup is dissipated through the heat transfer members into the chassis.

摘要： An accumulation unit accumulates, in a 1-line element corresponding to the main scanning direction, an electrical signal prepared by photoelectrically converting optical image information obtained by scanning an original image to be formed with a carriage in the subscanning direction. A magnification setting unit sets the copy magnification. A speed change unit changes the moving speed of the carriage in accordance with the copy magnification, and when the set copy magnification is equal to or smaller than a certain magnification in reduction, changes the carriage moving speed to 1/n (n: a natural number larger than 1) from the relationship between the current magnification and the carriage moving speed. A preprocessing unit converts the electrical signal into a digital signal, has a line memory for storing 1-line input image data in the main scanning direction, performs arithmetic processing for multilevel n-line data in the main scanning direction to change the subscanning magnification in reduction, and outputs 1-line output image data in the main scanning direction. An image data processing unit performs predetermined image data processing including processing of receiving for each pixel the 1-line output image data in the main scanning direction output from the preprocessing unit, and converting the image data into binary data.
