Filed: 1986-02-17
Abstract: PURPOSE:To reduce the substantial movable mass and to attain a compact and simplified optical disk device by turning both an objective lens and a light wave guide means by means of a rotary means as a movable optical system. CONSTITUTION:A fixed optical system 1 is set on a base board 10 together with a prism, the rotary means 2a and 2b which can turn the prism by a minute angle, and a rotary means 5 which turns an optical disk 11 within a horizontal surface. In addition, a light wave guide means 3 and an objective lens 4 are set on the means 5. The lens 4 can be seen as an image 4' of the lens 4 on an extended line of the optical axis L when a reflecting surface 3a is viewed from the direction E shown in the figure. When the lens 4 is turned round the rotary axis center P of the lens 4, the image 4' is also turned round the center P. Here the center P is coincident with the axis L and therefore the image 4' seems as if it turned round its own center optical axis. That is, the shift of an optical axis is never caused by rotations.

Abstract: PURPOSE: To reduce a fluctuation in pushing up force of a bottom plate according to a mounting quantity of paper by positioning a center of rotation on a bisector substantially perpendicular to a line connecting both engaging points with a tongue in both boundary positions in a movable area for a paper mounting member and eliminating an unnecessary contact fluctuation between the bottom plate and the tip of the tongue. CONSTITUTION: In a bottom plate 2 in a waiting condition, a pressing point by a tongue 6 is assumed to be a point C1 . A point, at which the point C1 arrives when the bottom plate 2 is moved upward to the uppermost position, is assumed to be a point C2 . A rotation fulcrum O2 of the tongue 6 is positioned on the vertical bisector of a solid line connecting the both points C1 , C2 .
