摘要： A lens drive system includes a lens frame having a lens element; a nut member secured to the lens frame, and which are both movable in an optical axis direction without rotating; a feed screw shaft having a male thread portion and a non-threaded portion, the male thread portion being engaged with a screw hole of the nut member; a motor for rotating the feed screw shaft; and a biasing member for biasing the nut member in a first direction toward the male thread portion. When the feed screw shaft is rotated to move the nut member and the lens frame in a second direction toward the non-thread portion, the female thread portion is disengaged from the male thread portion to move onto the non-threaded portion before the lens frame or the nut member abuts against an element of the lens drive system and stops thereby.

摘要： A lens drive system includes a lens frame having a lens element; a nut member secured to the lens frame; a feed screw shaft having a male thread portion and a non-threaded portion, the male thread portion engaged with a screw hole of the nut member; an engagement portion formed on the nut member and having a deformable screw-engaging portion engaged with the male thread portion; and a motor for rotating the feed screw shaft. The screw-engaging portion is disengaged from the male thread portion when a large force is applied to the engagement portion in an axial direction. When the linear movement of the lens frame and the nut member is restricted during rotation of the feed screw shaft, the engagement portion remains on the male thread portion of the feed screw shaft while the female thread portion is moved onto the non-thread portion.

摘要： A housing includes a first portion and second portion. Each of the first and second portions supports a mirror and are connected and prevented from independent movement through a cover glass plate. The connection between the portions of the housing reduces the amount of angular change of mirrors within the housing resulting from a change in temperature, and thereby reduces the amount of displacement of a reading point of an image receiving element during the temperature change. The reading point is projected along an optical path including multiple reflections from the mirrors. A first connection device tightly fits the cover glass plate between the first and second portions of the housing, and a second connection device adheres the cover glass plate to the first and second portions of the housing.

摘要： An image reading apparatus equipped In an electronic copying apparatus has a variable-power optical system including a first and second fixed focus lens group mounted on a lens mount base. Each lens group has a different magnifying power. The lens mount base is moved by a motor to a partial position and then by a biasing mechanism to the final position such that in one final position the optical axis of the first lens group is aligned with the incident ray axis, and in another final position the optical axis of the second lens group is aligned with the incident ray axis. Further when the first lens group is employed a movable reflecting mirror is positioned such that it is out of the incident ray axis. When the second lens group is employed, the movable reflecting mirror is positioned such that is placed in the incident ray axis to reflect the incident ray to the second lens group. Further, the reflecting mirror is moved in conjunction with the movement of the lens mount base. The movable reflecting mirror is further held in place by a retaining mechanism to prevent the movable reflecting mirror from being accidentally moved from the desired position.
摘要翻译：在电子复印装置中配备的图像读取装置具有包括安装在透镜安装基座上的第一和第二固定焦点透镜组的可变光学系统。每个镜头组具有不同的放大倍率。透镜安装基座由电动机移动到局部位置，然后通过偏置机构移动到最终位置，使得在一个最终位置中，第一透镜组的光轴与入射光线轴对准，并且在另一最终位置第二透镜组的光轴与入射光线轴对准。此外，当使用第一透镜组时，可移动反射镜被定位成使得其不在入射光线轴线之外。当使用第二透镜组时，可移动反射镜被定位成使其位于入射光线轴线中以将入射光线反射到第二透镜组。此外，反射镜与透镜安装基座的移动一起移动。可移动反射镜通过保持机构进一步保持在适当位置，以防止可移动反射镜意外地从期望位置移动。
