摘要： An optical deflector is provided with a scanning mirror which is rotatable about a shaft and accompanied by a sleeve and hub. The pneumatic pressure around the mirror which is located within a cavity formed by a motor case of the deflector is maintained lower than an inside pneumatic pressure of a pneumatic pressure creation arrangement. The arrangement has the shaft provided with herringbone grooves engraved on the periphery thereof and the sleeve rotatable about the shaft together with the hub and the scanning mirror. When the scanning mirror rotates about the shaft, windage loss may be reduced, and when the inside pneumatic pressure between the shaft and the sleeve is kept higher than the atmospheric pressure, the rigidity of the shaft may be maintained during the rotation of scanning mirror about the shaft.

摘要： An aerostatic bearing comprises a bearing base having a plurality of first through-holes for air intake, a bearing clearance being formed between the bearing surface and the thrust shaft, and a self-controlled restrictor disposed so as to form a restricting spacing with the reverse surface of the bearing base, the self-controlled restrictor being adapted for automatically adjusting the flow rate of air supplied to the bearing surface corresponding to the variation of the pressure on the bearing surface. The self-controlled restrictor has a restricting disc and a circular leaf spring. The restricting disc has a second through-hole at the center. The restricting disc is held by an O ring that also functions as a fluid sealing. The second through-hole is adapted for supplying air to the restricting spacing. The circular leaf spring is integrally formed with the restricting disc of a bottomed cylindrical member. Air supplied from the second through-hole to the restricting spacing flows as a diverging flow. Thus, a restoring force is applied corresponding to the deviation of the angle of the restricting disc.
