摘要： A sheet processor subjecting a sheet having been conveyed forward to processing along a direction perpendicular to a conveyance direction of the sheet, includes: a processing unit performing the processing; and a receiving unit receiving the processing unit therein in a state capable of perfecting the processing on the sheet, and the processing unit includes a first processing tool 4A and a second processing tool 4B disposed to vertically oppose each other with a conveyance surface of the sheet disposed therebetween, and the receiving unit includes at least one receiver that removably receives the first processing tool 4A and the second processing tool 4B in the state capable of performing the processing on the sheet, with arbitrarily selected one of the first processing tool 4A and the second processing tool 4B disposed above the conveyance surface, and with arbitrarily selected another of the first processing tool 4A and the second processing tool 4B disposed below the conveyance surface.

摘要： A feeding device comprises a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding of moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.

摘要： A slitter comprising: an upper rotary blade; a lower rotary blade; an upper housing for holding the upper rotary blade; and a lower housing for holding the lower rotary blade, the slitter being constructed such that the both rotary blades revolve in a manner that a tip on a cutting surface side of the upper rotary blade and a tip on a cutting surface side of the lower rotary blade are rubbed together so that a sheet passing through between the both rotary blades is cut, wherein the upper rotary blade is cantilevered on the cutting surface side by a cantilevered supporting part and the lower rotary blade is cantilevered on a non-cutting surface side by a cantilevered supporting part.
