摘要： A paper feeder comprises an acquiring device, a driving roller, driven rollers, a driven roller supporter, a driver, and a controller. The acquiring device acquires thickness information on a sheet of paper. The driving roller rotates by being supplied with torque. The driven rollers rotate with the driving roller when in compressive contact with the driving roller. The driven roller supporter so supports the driven rollers that each of them can rotate under a different rotational load. The driver changes the position of the driven roller supporter relative to the driving roller. The controller selects one of the driven rollers on the basis of the thickness information and so activates the driver as to bring the selected roller into compressive contact with the driving roller.

摘要： A feeding device according to the present invention holds a pile of sheets of paper in it. Feed force so acts selectively on a specified region of the upper side of the held top sheet as to feed the held sheets one after one in a feed direction. The feeding device includes a flat press plate and a support. The press plate is not smaller in the feed direction and the cross directions perpendicular to the feed direction than the maximum size of the sheets which can be held in the main body. The press plate is not larger in the feed and cross directions than the inner size of the main body. The press plate has a first opening formed over the specified region. The press plate is supported vertically movably above the held sheets by the support.

摘要： An image forming apparatus includes the first image forming section for forming color images, and the second image forming section for forming monochrome images, wherein the first image forming section is slidable through an opening formed on the front face of the main body, while the second image forming section is slidable through an opening formed on the side face of the main body so that the first and second image forming sections slide in mutually orthogonal directions. With this arrangement, various maintenance operations of each unit can be performed while suppressing a reduction in strength of the main body, whereby degradation of image quality with life can be avoided for a long period of time.
