摘要： Paper regulating mechanism in a paper feed cassette for accommodating paper sheets , has: a regulation guide plate disposed below a bottom plate, on which are placed the paper sheets, and formed with a slit having a predetermined width; upper plate-shaped portions against which the paper sheets come into abutment; lower guided portions disposed at the lower ends of said upper plate-shaped portions and so loosely fitted in said slit as to easily move; rollers connected to said upper plate-shaped portions or said lower guided portions and rotatably abutting against said regulating guide plate; and lock members for fixing said upper plate-shaped portions in arbitrary positions with respect to said regulation guide plate.

摘要： Disclosed is a paper feed mechanism in which copy paper stacked on a paper support member such as a manual insertion tray is fed along the sheet transport direction in a nipped state between an upper roller and a lower roller. The upper roller has, on its outer surface in the described order with respect to the rotational direction, a non-contact area which is not brought into pressing contact with the copy paper and the lower roller, a first contact area which comes into pressing contact with the copy paper and the lower roller and whose frictional coefficient relative to copy paper is set small, and a second contact area which comes into pressing contact with the copy paper and the lower roller and whose frictional coefficient relative to copy paper is set large. The lower roller is mounted on a torque limiter. The lower roller is rotated in a direction opposite to the sheet transport direction via the torque limiter when not coming into pressing contact with the first and second contact areas of the upper roller, while rotated in the sheet transport direction following the rotation of the upper roller when coming into pressing contact with the first and second contact areas of the upper roller.
摘要翻译： 公开了一种进纸机构，其中堆叠在诸如手动插入托盘的纸张支撑构件上的复印纸沿着纸张输送方向以上辊和下辊之间的夹持状态进给。 上辊在其外表面上以相对于旋转方向的所述顺序具有不与复印纸和下辊压接的非接触区域，进入压接的第一接触区域 并且其相对于复印纸的摩擦系数设定得较小，并且与复印纸和下辊进行压力接触并且其相对于复印纸的摩擦系数设定得较大的第二接触区域。 下辊安装在扭矩限制器上。 当不与上辊的第一和第二接触区域进行压力接触时，下辊沿着与纸张输送方向相反的方向经由扭矩限制器旋转，同时沿着上辊的旋转沿着纸张传送方向旋转 当与上辊的第一和第二接触区域进行压接时。
