| 271208000 | With means to discharge static electricity | 7 |
| 20080290591 | Static eliminator of sheet handling device - A static eliminator, provided in a sheet-fed printing press for doing printing on a sheet of paper, and equipped with static electricity removing devices for removing static electricity building up in the sheet, comprises: electrostatic sensors for detecting the amount of static electricity of the sheet; a display/selector having a display section for indicating information to an operator, and a selection section for selecting whether control over the static electricity removing devices is exercised or not; and a control device for controlling the display/selector so as to indicate the information in the display section of the display/selector, and also controlling the static electricity removing devices, based on the information from the electrostatic sensors. | 11-27-2008 |
| 20110215519 | SHEET FINISHING APPARATUS AND IMAGE FORMING APPARATUS - A sheet finishing apparatus includes an outer wall having a discharge port of a sheet, a movable tray that stacks the sheet discharged from the discharge port, moves vertically along the outer surface of the outer wall according to a stack amount of the sheet, and has a stacking surface inclined to cause a position of a trailing edge of a sheet to become lower than a position of a leading edge of the sheet, and a support member that is provided at a position outside the outer surface of the outer wall, contacts the trailing edge of the sheet stacked on the movable tray to hold the sheet, and removes static electricity from the sheet. | 09-08-2011 |
| 20130285311 | SHEET EJECTION DEVICE - A sheet ejection device includes a plurality of second sheet abutting members and a plurality of conductive members. Each second sheet abutting member has a non-conductive sheet regulating surface that abuts on a rear end portion in an ejecting direction of each sheet on a sheet output tray to regulate movement thereof. Each conductive member is attached at a position lower than a sheet drop height position and in the vicinity of each second sheet abutting member in a grounded state in the sheet width direction. Each conductive member attracts a rear end portion in the ejecting direction of a sheet on the uppermost layer of a plurality of sheets stacked on the sheet output tray, up to the sheet drop height position on the sheet regulating surface of the second sheet abutting member. | 10-31-2013 |
| 20150054215 | SHEET DISCHARGE DEVICE AND IMAGE FORMING APPARATUS - A sheet discharge device includes a sheet discharge portion configured to discharge a sheet, a destaticizing brush coming into contact with the sheet discharged by the sheet discharge portion and destaticizing the sheet, and a guide member turning by being pushed by the sheet discharged by the sheet discharge portion and guiding the sheet to a stacking portion on which the discharged sheet is to be stacked. The guide member includes a guide portion guiding the discharged sheet to the stacking portion and a recede portion provided at a position facing the destaticizing brush and accepting the destaticizing brush deformed by being pushed by the sheet. | 02-26-2015 |
| 20160083215 | IMAGE FORMING APPARATUS INCLUDING DISCHARGE UNIT - An image forming apparatus includes a discharge unit, a discharge roller, a pressing member, and a reinforcing frame. The discharge unit includes a guide member that forms a discharge path that guides a sheet member to a sheet discharge port. The discharge roller discharges the sheet member to outside from the sheet discharge port. The pressing member projects from the guide member toward the discharge path, and contacts and presses the sheet member that is passing through the discharge path. The reinforcing frame, formed from a metal plate material, is made conductive with a reference potential portion of the apparatus main body and reinforces the discharge unit by being, together with the discharge unit, fixed to the apparatus main body in a state of covering a part of the guide member to which the pressing member is attached. | 03-24-2016 |
| 20160185554 | PRINT MEDIA DISCHARGE UNIT - The invention pertains to a print media discharge unit, comprising a print media transport path along which in operation a sheet of print media is transported in a transport direction, the print media transport path is defined by a first electrically isolating print media guide and a second electrically isolating print media guide, the print media discharge unit further comprising an electrically grounded electrically conductive discharge element extending through an opening in at least one of said first and second electrically isolating print media guides into the print media transport path, wherein at least one of said first and second electrically isolating print media guide comprise a plurality of guidance ribs aligned substantially in the transport direction at an angle with respect to the transport direction. | 06-30-2016 |
