Abstract: In a vibration preventing damper forming method and a vibration preventing damper integrally formed with a mechanical chassis according to the present invention, an opening side end portion 9e of a damper housing 9 and a vibration preventing damper forming portion of a mechanical chassis 6 are made of a resin. The damper housing 9 is mounted on the vibration preventing damper forming portion by the fixture of the resin portions. Thus, a vibration preventing damper 8 is integrally formed with the mechanical chassis 6. For this reason, in supporting in a vibration proof manner and in a floating matter the mechanical chassis 6 within an interior of a casing 10 by means of the vibration preventing damper 8, it is possible to improve the working efficiency in mounting the mechanical chassis 6 to the casing 10 and to cope with the requirement of miniaturization of a mounting space between the interior of the casing 10 and the mechanical chassis 6.

Abstract: A damper has a flexible portion formed of a rubber-like elastic material, such as thermoplastic elastomer, and a lid portion whose inner peripheral portion is formed of the rubber-like elastic material. The flexible portion and the lid portion are respectively equipped with mounting recesses into which mounting shaft members oppositely arranged on a casing of a reproduction device are inserted to hold the damper. With this construction, there is no need to mount the damper such that the lid portion faces the side plate or the bottom plate of the casing. Therefore, it is possible to reduce the thickness of the reproduction device, and to increase the degree of freedom in the design of the casing. Further, since the damper is supported in a floating state, it is possible to obtain a superior vibration damping effect whether the device is installed in a vertical or horizontal position.

Abstract: An automatic support pillar transfer mechanism is provided that enables an enlarged transfer range, reduced produce failure and mass-production. The touch sensors 17a to 7c are arranged on the moving section 12 to measure the plane orientation of the surface of the jig 7. The jig adjusting section 6 is driven based on the measurement results on the plane orientations of surfaces of the jig 7 to adjust the surface of the jig 7 in parallel. With plural support pillars 15 sucked and held at predetermined intervals by the jig 7 adjusted in parallel, the bonding agent coated substrate 14 attached on the moving section 12 is descended to coat the bonding agent 13 onto the one ends of the support pillars 15. The substrate 16 to which the support pillars 15 are transferred is attached to the moving section 12. Variations in plane orientation of surfaces of the substrate 16 are respectively measured by means of the touch sensors 5a to 5c.

Abstract: The present invention employs a high elastic body with E value more than 1.2.times.10.sup.4 kg/cm.sup.2 as the high elastic body to be used for a body frame which supports a mechanical chassis of optical disk equipment or the like, while it also employs an elastic body with E value less than 1.0.times.10.sup.4 kg/cm.sup.2 which aims at vibration damping and with rubber hardness JIS-A Class less than 70 as a low elastic body to be used for an installing portion of the mechanical chassis. By integral-molding both low and high elastic bodies, a frame damper is formed, thereby controlling and isolating even vibration caused by high double-speed rotation of a disk and by integral-molding both the low elastic body of the installing portion of the mechanical chassis and the high elastic body of the body frame, it omits an assembly process using a fixing pin and improves working efficiency.

Abstract: To provide an an.isotropic damper using an elastic member having an E value two times or more larger than that of an elastic member for damping the vibration in the vertical direction to a portion for supporting the rotary part of an optical disk or the like and a mechanical chassis mounting an optical pickup and to the portion for damping the vibration in the planar direction, and comprising two types of elastic members for controlling the fluctuation in the relative distance between the optical pickup and the disk.
