An elastic roll includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate, and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.

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.

An image forming apparatus includes a cutting part cutting a medium, a transfer part arranged on a downstream side of the cutting part in a carrying direction and transfers a developer image to the medium; a flexure forming part having a guide part and forms a flexure of the medium by bending the medium between the cutting part and the transfer part in the carrying direction; and an opposing part that is arranged opposing the flexure forming part via a carrying path through which the medium is carried, wherein the guide part performs a retreat movement either before or after the cutting part starts to cut the medium, wherein the retreat movement is a movement of the guide part in which the guide part moves in a direction away from the opposing part.

A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

An automatic document feeder includes a media path to route media through an image read area for the automatic document feeder, and a media ramp supported along the media path after the image read area, with an end of the media ramp to rotate in a direction transverse to the media path.

A dispenser for dispensing sheet product is provided. The dispenser includes a housing with an outlet through which sheet product is dispensed. A knife drum is rotatable with respect to the housing. A knife is movable between a retracted position within the knife drum and an extended position where the knife protrudes outside of the knife drum to cut the sheet product. A cam follower surface is fixed with respect to the housing. A cam follower is attached to the knife and operable to engage the cam follower surface and travel therealong to transition the knife between the retracted position and the extended position. A spring assembly biases the knife drum during rotation toward a predetermined position. The spring assembly comprises a first spring and a second spring. The spring assembly is attached at a single mount position that is fixed with respect to the housing.

A sheet transporting device includes: plural pairs of transporting rolls that are arranged adjacent to one another in a direction of transport of a sheet; and a component configured to switch individual positions of the plural pairs of transporting rolls between a nipping position and an unnipping position, the component being a single switching component capable of switching a state of nipping by the plural pairs of transporting rolls between a state where all of the plural pairs of transporting rolls are in the nipping position, a state where some of the plural pairs of transporting rolls are in the nipping position while remaining ones of the plural pairs of transporting rolls are in the unnipping position, and a state where all of the plural pairs of transporting rolls are in the unnipping position.

According to one aspect of the present disclosure, an applying unit that can be connected to a printer and apply an adhesive to a recording sheet includes: a roller configured to transport the recording sheet that is discharged from the printer; a sensor configured to detect the bend of the recording sheet; an applying portion configured to apply the adhesive to the recording sheet; and a control device configured to adjust the rotation speed of the roller according to the value detected by the sensor.

An automatic document feeder includes a media path to route media through an image read area for the automatic document feeder, and a media ramp supported along the media path after the image read area, with an end of the media ramp to rotate in a direction transverse to the media path.

A medium aligning apparatus includes a load tray including a load surface on which a medium discharged from a discharge member that discharges a medium is loaded, a first aligning surface that aligns a plurality of mediums loaded on the load tray by positioning rear ends of the mediums, and a second aligning surface that aligns the mediums by positioning the rear ends of the mediums loaded on the load tray. In the medium aligning apparatus, the first aligning surface and the second aligning surface are switchable, and an angle formed between a wall surface in the discharge tray that receives the mediums discharged from the load tray, the wall surface having the rear ends of the mediums come in contact therewith, and the second aligning surface is smaller than an angle formed between the wall surface and the first aligning surface.
