Here, the filter unit is configured to be pulled out in a direction away from the device main body.

A medium conveying apparatus includes a storage device, a feed roller to feed a medium, and a processor to determine whether a conveyance abnormality of the medium fed by the feed roller has occurred, store in the storage device that the conveyance abnormality has occurred and stop feeding of the medium when the processor determines that the conveyance abnormality has occurred, and notify a user of a cleaning instruction or a replacement instruction of the feed roller based on an occurrence degree of the conveyance abnormality for a plurality of media fed by the feed roller.

An image forming apparatus has: a cassette which stores a sheet; a pickup roller which picks up the sheet inside the cassette; a feed roller which feeds the sheet picked up by the pickup roller toward an image forming portion; and a retard roller which is pressed against the feed roller and forms a separation nip. In addition, the image forming apparatus has a conveying guide which guides the sheet picked up by the pickup roller to the separation nip. A first guide member of the conveying guide is configured to be slidable in a drawing direction when the feed roller is replaced, and the conveying guide is formed of a material whose property of light transmittance of light having a wavelength of 360 nm to 420 nm is 80% or more. The feed roller is detachable from the one end of a shaft in a state in which the cassette is drawn out along the rail and the conveying guide is slid in the drawing direction.

A feeding unit includes: a retard roller; a holder section; a protruding section; an accommodating section; a pressing section; a first restricting section; and a second restricting section. The holder section rotatably holds the retard roller. The protruding section serves as a rocking fulcrum of the holder section. The accommodating section accommodates the holder section. The pressing section presses the holder section. The first restricting section restricts movement of the holder section in a retreating direction. The second restricting section restricts movement of the holder section in a direction opposite to the retreating direction. The pressing section is arranged so as to deviate in a Y direction with respect to a virtual line passing through a middle point of the protruding section and a middle point of the first restricting section. The holder section comes into contact with the first restricting section and the second restricting section.

The invention relates to an apparatus, in particular a roll cross cutter, for forming a shingled stream of underlapping or overlapping sheets, in particular paper or cardboard sheets, comprising a transport device for transporting sheets, a shingling device for underlapping or overlapping of the sheets at least in some regions, a braking device following the shingling device in the transport direction of the sheets for braking of shingled sheets, in particular by the formation of a brake gap for the passage of sheets brought together in a shingled manner, and a cross-cutting device upstream of the shingling device for cutting a material strip into individual sheets. According to the invention, an intake section is provided between the shingling device and the braking device for intake and further transport of a sheet, trailing in the shingled stream, into the braking device.

A roll feed includes a base body, a first tube roll having a rolling surface and a first bearing shaft, wherein the base body is configured to support the first tube roll and the first bearing shaft. The first bearing shaft and the first tube roll are configured to be detachably connected to each other for a rotationally fixed connection, wherein the base body is configured such that the first tube roll can be removed from the base body in an axial direction, wherein the axial direction is substantially parallel to an axis of rotation of the first tube roll.

A medium feeding apparatus includes a medium mounting section, a movable edge guide that guides both edges of the medium mounted on the medium mounting section and has a first edge guide and a second edge guide, a feeding section, and a width adjuster configured to adjust a guide width depending on the medium. The width adjuster includes a first adjuster having a first holding section and a first guiding section, and the second adjuster having a second holding section and a second guiding section. The first holding section holds a part of the first edge guide, the first guiding section guides the edge of the medium between the first edge guide and the second guiding section, the second holding section holds a part of the second edge guide, and the second guiding section guides the edge of the medium between the second edge guide and the first guiding section.

A sheet conveyance apparatus includes a shaft portion, a roller member, and a guide member. The roller member includes a hole portion with an opening through which the shaft portion is fitted with the hole portion. At least a part of the guide member is located upstream of an end of the shaft portion in an attaching direction of the roller member. A distance between rotation axes of the roller member and the shaft portion is smaller than a difference between a radius of the opening and a radius of the end of the shaft portion in a state where an outer circumferential surface of the roller member is in contact with the guide member at a position upstream of the end of the shaft portion in the attaching direction.

An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

An image forming apparatus has an apparatus main body, a sheet conveyance passage, a cover member, a conveyance unit, a sheet tray, a first sheet feeding portion, and a feed unit. The sheet conveyance passage is inside the apparatus main body. The conveyance unit is inside the cover member and is supported to be pivotable between an open position and a closed position. The first sheet feeding portion has a feed unit. The conveyance unit has a swing guide of which a lower end part is swingably supported on the apparatus main body and which, in the closed position, is located in a first position to face the feed unit and constitute part of the sheet conveyance passage and, in the open position, is located in a second position to be located away from the feed unit.
