摘要： PURPOSE: To keep feeding roll contact force proper even when paper sheets are reduced from a tray by providing a movable type support means to apply reasonably constant vertical force between the paper sheet on the top part and a paper sheet feeding means regardless of size and density of the paper sheets on the movable tray by adjusting a spring rate of a plate spring means. CONSTITUTION: A paper sheet on the top part of a stack of the wheets placed on a paper sheet tray 24 is put at a specified position to feed it into a processing machine by a feeding roll. Thereafter, vertical force between the feeding roll and one sheet on the top part of the paper sheets is maintained proper throughout overall feeding motion against weight of the paper sheets along an extensive rage regardless of the remaining number in this tray 24 by adjusting the spring rate of the plate spring 18. This adjustment is carried out by providing a movable type support member 17 against the plate spring 18 and changing the spring rate in accordance with movement of the movable type support member 17.

摘要： PURPOSE:To prevent sheets from being fed in a superposed condition and being fed erroneously, by changing the pressing force of a pressing means for pressing a sheet against a feed roller, in association with a sheet guide. CONSTITUTION:A sheet 2 which is loaded on a lift plate 3, is pressed against a feed roller 1 by means of a spring 10 through the intermediary of the lift plate 3. If the size of a sheet is small, levers 8a, 8b do not make contact with cam parts 9a, 9b on a sheet guide so that a spring attaching surface 7 is located at a lowest position. If the size of a sheet is large, the cam parts 9a, 9b are associatingly opened in the direction of the arrow 5, and the levers 8a, 8b are rotated in the direction of the arrow 4 by the cam parts 9a, 9b on the sheet guide. Further, the spring attaching surface 7 ascends so as to decrease the length of the spring 10, thereby the sheet 2 is pressed against the feed roller 1 with a relatively large force.

摘要： PURPOSE:To reduce the frictional force between the lowermost sheet of paper and a support plate by providing a convex or concave groove directed to the direction of delivering said sheet on the rear portion of the upper surface of a lowermost sheet supporting plate to introduce deeply between said sheet and support plate gas jetted from a blasting means. CONSTITUTION:Air injected from an air blasting unit 5 is supplied between laminated blanks 7 and between the lowermost blank and a tray bottom plate 1. As a convex groove 3 is then provided in the rear portion of the tray bottom plate 1, a gap between the lowermost blank 8 and the tray bottom plate 1 is widened toward the rear portion of the tray bottom portion 1. As a result, although the laminated blanks 7 are mounted long along the direction of feeding out, air supplied between the lowermost blank 8 and the tray bottom plate 1 flows rearward to separate the lowermost blank 8 completely upward from the tray bottom plate 1 and thus reduce the frictional force acting between both 8 and 1.
摘要翻译：目的：通过提供一个凸形或凹槽来减少最下面的纸张与支撑板之间的摩擦力，该凸形或凹形的凹槽指向在最下面的纸张支撑板的上表面的后部上输送所述纸张的方向，所述片材和支撑板气体从喷砂装置喷射。构成：从空气喷射单元5喷射的空气被供给到层叠坯料7之间并且在最下面的坯料和托盘底板1之间。由于在托盘底板1的后部设置凸槽3，最下面的坯料8和托盘底板1朝向托盘底部1的后部加宽。结果，尽管叠层坯料7沿着送出方向安装得很长，但是在最下面的坯料8和托盘底板1向后流动，使最下面的坯料8从托盘底板1完全向上分离，从而减小了作用在8和1之间的摩擦力。
