    摘要： A sheet feeder includes a feeder for feeding a sheet, a cassette (4B) for containing a plurality of stacks of small sized sheets side by side therein, the cassette including a plurality of biasing members (42a,42b) for biasing the respective stacks of small sized sheets upwards so as to bring uppermost sheets of the respective stacks into contact with the feeder, a plurality of sheet detectors (1a,1b) arranged in positions corresponding to the respective stacks of sheets for detecting the height of the respective stacks of sheets contained in the cassette, and a controller (26) responsive to the plurality of sheet detectors for determining the absence of sheet in the cassette when at least one of the plurality of sheet detectors detects that the height of the stack has become lower than a predetermined height, and stopping a sheet feeding operation. This sheet feeder prevents the transfer device of an image forming apparatus from being smeared due to the fact that the small sized sheet is fed from only one stack.

    摘要翻译： 一种纸张馈送器包括用于馈送纸张的供纸器，用于在其中并排容纳多个小尺寸纸张堆叠的盒子（4B），所述盒子包括多个偏压元件（42a，42b），用于偏置 向上的小尺寸的片材，以便使各个叠层的最上面的片材与馈送器接触;多个片材检测器（1a，1b），布置在与各个片材堆叠对应的位置中，用于检测各个片材堆叠的高度 以及控制器（26），其响应于所述多个纸张检测器，用于当所述多个纸张检测器中的至少一个检测到所述堆叠的高度已经变得低于预定的纸张时，确定所述纸盒中没有纸张 高度，停止送纸操作。 由于小尺寸片材仅从一个堆叠进给的事实，该片材进给器防止图像形成装置的传送装置被弄脏。

    摘要： A sheet discharging device is provided with a sheet discharger including first and second rollers (18a,18b) and arranged downstream from the fixing device (17), a contact point (N) of the first and second rollers being located toward the pressing roller from a tangent line (B) on a point of a circumferential surface of the heat heating roller which intersects with a straight line connecting centers of the heating and pressing rollers, and a drive mechanism for driving the first roller and the heating roller so that a speed of the first roller at the circumferential surface thereof is greater than that of the heating roller. Accordingly, a sheet curled in the fixing device can be straightened with a simple construction.

    摘要： An image forming apparatus includes a mount portion which permits a cassette containing a plurality of stacks of sheets arranged side by side in rows to be mounted to the image forming apparatus; a feeder for feeding sheets side by side in a state where the cassette is mounted to the mount portion; an imaging assembly for forming an image on each of the sheets being fed side by side; a sheet sensor for detecting the presence or absence of sheet contained in the cassette for each row; and a control unit for, when the absence of sheet is detected in any of the rows, stopping at least an image forming operation along a corresponding transport path. Accordingly, even if all the sheets run out in any one of the rows, the corresponding transport path and the like can be prevented from getting smeared due to the image forming operation carried out despite the fact that no sheets are being fed.

    摘要翻译： 图像形成装置包括安装部分，其允许包含并排布置的多个堆叠的片材的盒子被安装到图像形成装置; 用于在盒安装到安装部分的状态下并排地供给片材的馈送器; 用于在每个所述片材上形成图像的成像组件被并排供给; 用于检测每行中包含在所述盒中的片材的存在或不存在的片材传感器; 以及控制单元，用于当在任何行中检测到不存在纸张时，至少停止沿着相应的传送路径的图像形成操作。 因此，即使所有的片材都在任何一行排出，也可以防止由于进行图像形成操作而导致相应的传送路径等被弄脏，尽管没有进纸。
