摘要： A sheet feeder includes: air blowing device which blows air from a direction of side edges of a stack of sheets loaded in a predetermined location, paper feed device which separates one sheet from the stack of sheets to which air is blown by the air blowing device and which feeds the thus-separated sheet from the predetermined location, and air flow regulation device which is provided in an elevated position above the stack of sheets loaded in the predetermined location and which regulates the passage of the air flow blown toward the stack of sheets from the air blowing device.

摘要： A compact image formation apparatus forms an image on an image support, discharges the image support supporting an image to an outside of the apparatus and facilitates jam removal. The image formation apparatus has all operation portions for performing operations from the outside of the image formation apparatus located on three operation faces including a top face, a front, and either a left side face or a right side face of the image formation apparatus. A rear face and the other of the left side face or right side face of the image formation apparatus are set to be non-operation faces.

摘要： A plurality of containers store sheets to be fed, and a plurality of sheet guides bias the sheets in the containers toward a predetermined location. Detectors determine the positions of the sheet guides and output position data corresponding to the size of sheets disposed in each of the plurality of containers. A memory circuit store sheet size data for a plurality of sheet size groups, and include, and at least a portion of sheet sizes from the plurality of sheet size groups are of similar dimension. A first comparison circuit compares selected position data with sheet size data stored in the memory to determine if sheets in a selected container are included in either a first group, a second group or the similarly dimensioned portion of the first and second groups. A second comparison circuit compares position data other than the selected position data with sheet size data stored in the memory circuit to determine if sheets in a container other than the selected container are excluded from the similarly dimensioned portion when the selected position data corresponds to a sheet size included in the similarly dimensioned portion. A circuit determines the sheet size of sheets in the selected container based upon position data corresponding to a container other than the selected container when position data corresponding to the other container does not correspond to a sheet size in the similarly dimensioned portion.
摘要翻译：多个容器存储待进给的纸张，并且多个纸张引导件将容器中的纸张朝向预定位置偏压。检测器确定与设置在多个容器中的每一个中的片材的尺寸对应的片材引导件和输出位置数据的位置。记忆电路存储多个片材尺寸组的片材尺寸数据，并且包括，并且来自多个片材尺寸组的片材尺寸的至少一部分具有相似的尺寸。第一比较电路将选择的位置数据与存储在存储器中的纸张尺寸数据进行比较，以确定所选容器中的纸张是否包括在第一组，第二组或第一组和第二组的相似尺寸的部分中。第二比较电路将除选择的位置数据之外的位置数据与存储在存储器电路中的纸张尺寸数据进行比较，以确定当所选择的位置数据对应于纸张时，除了所选择的容器之外的容器中的纸张是否被排除在类似尺寸的部分之外尺寸包括在相似尺寸的部分中。电路基于与所选择的容器相对应的容器对应的位置数据，确定所选择的容器中的片材的片材尺寸，当与另一个容器对应的位置数据与相似尺寸的部分中的片材尺寸不对应时。
