Title: Image blur corrector
Inventor: ONUKI ICHIRO
IPC: G03B5/00
Filed: 1992-06-03
Abstract: PURPOSE:To provide the image blur corrector which is miniaturized as compared with the conventional device and constituted so as to perform the yawing and pitching of a correction lens. CONSTITUTION:In this image blur corrector, a lens holding frame holding the correction lens is supported by a supporting means which enables yawing and pitching. Guide shafts 45p and 45y are bent for sliding and guiding the lens holding frame 43 and when the lens holding frame 43 is moved along the shaft 45p, the pitching of the holding frame 43 is performed. When the holding frame 43 is moved along the shaft 45y, the yawing of the holding frame 43 is performed. Thus, the yawing and pitching (tilting) of the correction lens 41 can be performed. Therefore, abberation caused by a bent image face can be corrected with a simple optical system and further, yawing and pitching can be performed with simpler structure than the conventional structure.

Abstract: PURPOSE: To reduce leakage and to improve volume and compressing efficiencies by forming a low-friction film of 1W10μm only on a part of at least one end face of upper and lower bearing parts which is exposed to the inside of a cylinder.  
     CONSTITUTION: A clearance 5 in vertical direction between a cylinder 4 and a roller 1 is formed smaller than usual, and a film 10 of 1W10μm of a low-friction material is formed on an end face of an upper bearing 7.
