A removable raised tray system for a printing system generally includes a removable tray operatively arranged to receive print media thereon. The removable tray includes an upper tray surface having an electrically conductive material, a lower tray surface, and at least one tray leg that is connected to the removable tray, which is configured to support the removable tray at a position that is raised relative to a platform surface of a printer feeder or stacker. The at least one leg includes a releasable fastening assembly, such as a rare earth magnet, that releasably secures the removable tray to the platform surface thereby allowing the tray to easily attached and removed from the printer feeder or stacker. The electrically conductive material of the tray surface and the platform surface are electrically conductively connected to one another so as to prevent the build-up of static electricity.

The present invention is a spool holder that is an insert for inserting in the hole in a spool to frictionally engage the inner surface of the spool, and having an attachment mechanism that allows the insert to be attached to a surface, such as the vertical metallic side of a car. The attachment mechanism may include a number of magnets disposed in receptacles in the insert, or a number of small suction cups on the lateral sides of the insert.

An image forming apparatus includes an image forming unit that forms an image and a guiding member that guides a sheet on which the image has been formed by the image forming unit. At least one of irregularities and holes are formed on or in a surface of the guiding member that guides the sheet.

A magnetic sheet transport apparatus according to an embodiment includes a transport path on which a magnetic sheet having a magnetic flux is transported. A magnetic member is disposed on the transport path. A separation unit is disposed on the magnetic member. The separation unit causes the magnetic sheet to be separated from the magnetic member so that the magnetic sheet being transported on the transport path is not pushed onto the magnetic member by the magnetic flux.

A sheet conveyance apparatus includes a housing, a rotationally driven conductive shaft, a conveyance roller, a drive transmission unit, a conductive bearing member, a conductive discharging member, a cover member, and a conductive grounding member. The bearing member rotatably supports one end side of a shaft in a sheet width direction. The conductive discharging member is disposed in the openings. The discharging member discharges sheets by contacting the sheets. The cover member is secured to the sidewall along the one end side of the housing in the sheet width direction. The cover member includes a conductive grounding portion for electrical grounding. The conductive grounding member contacts the bearing member and the one end side of the discharging member along the sheet width direction. The grounding member conducts the bearing member and the discharging member to the grounding portion of the cover member.

A continuous winding method produces a continuously wound electrical device, such an undulator. A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.

A magnetic sheet transport apparatus according to an embodiment includes a transport path on which a magnetic sheet having a magnetic flux is transported. A magnetic member is disposed on the transport path. A separation unit is disposed on the magnetic member. The separation unit causes the magnetic sheet to be separated from the magnetic member so that the magnetic sheet being transported on the transport path is not pushed onto the magnetic member by the magnetic flux.

A dispenser assembly for dispensing a sheet from a roll of sheet material, which defines a cavity extending longitudinally, includes: a roll holder for removably holding the roll of sheet material being free to rotate relative to the roll holder; a base for supporting the roll holder and for coupling the dispenser assembly with an environment structure; and a pair of coupling elements including a first element coupled to the roll of sheet material and a second element integral to the roll holder. The first element is coupled in a free to rotate and removable manner relative to the second element by magnetic coupling. The first element includes a longitudinally extending engaging portion which is arranged to at least partially engage with an end portion of the cavity of the roll of sheet material so that the first element is fixedly secured to the roll of sheet material.

A sheet conveying apparatus which conveys a sheet includes: a first rotating member made of a material which is positive with respect to the sheet in a triboelectric series; and a second rotating member made of a material which is negative with respect to the sheet in the triboelectric series, wherein the first and second rotating members are arranged in a conveyance direction of the sheet and arranged to be contact with the same surface of the sheet, and a foreign material is removed from the conveyed sheet by the first and second rotating members.

A sheet feeding member is provided, which is made of a thermoplastic elastomer composition comprising: a base polymer including a polyurethane thermoplastic elastomer and a polyester thermoplastic elastomer; and at least one ion conductive agent selected from the group consisting of a quaternary ammonium salt and a lithium salt/polyol, wherein the ion conductive agent is present in a proportion of 0.2 to 4 parts by mass based on 100 parts by mass of the base polymer in the thermoplastic elastomer composition.
