20110089624 | ROTARY DIVERTER WITH FUNNEL SECTION - System for directing media from one an input media path to one of multiple output paths using a rotary diverter. The rotary diverter is a cylinder mounted for rotation at a crossover point, where input media paths and output media paths cross. The rotary diverter includes a funnel-shaped section longitudinally cut through the cylinder, the sides of the funnel-shaped section lying at an acute angle. A relatively narrow output end of the funnel-shaped section lies toward the apex of the angle, and a relatively wide input end lies opposite the apex. The input end is thus configured to receive media, and the output end is configured to output media. The rotary diverter can accept input media from one input media path, or from several paths, given the wide input section. | 04-21-2011 |

20080246207 | Feeding sheets into a photocopier - A simplified sheet sensor and registration gate for feeding print media sheets from a stack loaded by a user into a receptacle on a photocopier. The gate is pivoted on the mechanism and has a flag attached; and, upon user loading of sheets into the receptacle, the gate is pivoted against a locking arm and the flag is moved to actuate an optic sensor that sheets have been loaded. The locking arm is pivoted on the nudger roll arm and unlocks the gate when the nudger roll is moved down to contact the top sheet in the stack. When the sheet receptacle is unloaded, the gate is pivoted by gravity to the downward position and the locking arm pivots by gravity to reset. If the nudger is raised for sheet jam clearance, the locking arm is pivoted to clear the gate, allowing the gate to drop. The locking resets by gravity. | 10-09-2008 |
20080296837 | Gateless diverter - 'S' shaped paper path - In accordance with one aspect of the present exemplary embodiment, a system transports paper to prevent stubbing within a printing machine. The paper path facilitates transport of one or more sheets of paper from the first end to the second end, each sheet of paper has a leading edge. A first entry point is located between the first end and the second end that allows one or more sheets to enter the paper path in succession. A first nip is adjacent to the first entry point to direct the leading edge of the one or more sheets away from the first entry point. A second entry point is located a distance from the first entry point that allows one or more sheets to enter the paper path. A second nip is adjacent to the second entry point to direct the leading edge of the one or more sheets away from the second entry point. A gateless diverter directs the one or more sheets of paper through the paper path which includes a convex section that is adjacent to a concave section to divert the leading edge of each of the one or more sheets away from the first entry point and the second entry point. The one or more sheets of paper are advanced to the convex section via the first nip in advance to the concave section to the second nip. | 12-04-2008 |
20100117291 | SHEET SIZE DETECTION DEVICE - A sheet size detection device for detecting a size of sheets which are held in a sheet tray is disclosed. The device comprises first and second guide members, first and second brackets, and a plurality of switches. The first guide member is movable in accordance with a first dimension of the sheets. The second guide member is movable in accordance with a second dimension of the sheets. Each bracket is operatively connected to its respective guide member and includes a plurality of slots extending through a solid surface. The plurality of switches is configured for selective engagement by at least one of the brackets. The solid surface and the plurality of slots of each bracket are configured to interact with one another to selectively engage the plurality of switches. The selective engagement of the plurality of switches enables conveyance of two dimensions of the sheet size. | 05-13-2010 |
