摘要： A sheet conveying device (1) includes a controller (19) that detects the uppermost sheet (2A), lifts and stops the sheet stack (2) at a reference position, and detects and stores the position. The controller (19) attracts and conveys the uppermost sheet (2A) for a given number of times with the second detector (16) contacting it at the reference position, and calculates a variation amount of the detected angle to convert to a thickness of M sheets, and stores the result . Then, the controller (19) retracts the driven contact roller (16D) to a non-detecting position, and, each time the uppermost sheet (2A) is attracted by N sheets, lifts the sheet stack (2) based on the thickness of M sheets under N ≥ XM ("M" and "N" represent positive integers and "X" represents a positive integer equal to or greater than 1).

摘要： A sheet feeding apparatus includes a sheet containing tray (2) withdrawable from a housed position to a front side of an apparatus body. A sheet-feeding device is provided so as to feed sheets on the sheet containing tray in a direction perpendicular to a withdrawal direction (B) of the sheet containing tray. A pair of side aligning members (3,4) is also provided so as to align widthwise ends of the sheets. A rear side-aligning member (3) mounts a hitching member (15) so as to hitch and prevent a jam sheet from remaining in an apparatus body when the sheet containing tray is withdrawn. The hitching member includes a horizontally protruding plate so as to overhang the uppermost sheet (P') set on the sheet containing tray at a position a prescribed length downstream of a downstream end of the rear side-aligning member. A joining portion is also provided so as to join the projection plate and the rear side-aligning member. The joining portion positions a prescribed length behind a rear side end of the sheets.
摘要翻译：片材进给装置包括从容纳位置抽出到装置主体的前侧的片材容纳盘（2）。纸张供给装置被设置成在片材容纳盘的垂直于纸张容纳盘的取出方向（B）的方向上进给纸张。还设置有一对侧对齐构件（3,4），以便对齐纸张的宽度方向的两端。后侧对齐构件（3）安装挂钩构件（15），以便在收起托盘时钩住并阻止卡纸残留在装置主体中。挂钩构件包括水平突出的板，以便在后侧对齐构件的下游端的下游的规定长度的位置处伸出设置在片材容纳盘上的最上面的片材（P'）。还提供接合部分，以便连接突出板和后侧对准构件。接合部将片材的后侧端部的规定长度定位。
