An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.

An image scanner is configured to perform: controlling the sheet feed roller to feed the document supported on the sheet feed tray, controlling the conveyor to convey the fed document to the reading position, controlling the image sensor to read the image of the document at the reading position, and controlling the sheet discharge unit to discharge the read document to the sheet discharge tray; in response to detecting, by the sheet feed sensor, a state change from the first state to the second state, moving the movable plate upward until the sheet feed roller changes from the second state to the first state; after moving the movable plate, controlling the distance sensor to detect the document distance; and moving the sheet discharge unit vertically based on the detected document distance.

A paper sheet feeding unit includes: a plurality of feed rollers; a plurality of gate rollers respectively disposed opposite to the plurality of feed rollers in a one-to-one relationship; a biasing member that biases the plurality of gate rollers individually in a direction of the plurality of feed rollers; and a supporting member that supports the plurality of gate rollers and the biasing member.

A sheet supply device, a shredding device, a web forming device, and a sheet recycling system enabling smoothly supplying sheets regardless of the size and type of the sheets, and reducing equipment size. The sheet supply device includes a tray having a support surface on which a sheet is placed; a supplier configured to feed the sheet placed on the support surface; and a discharger from which the sheet is discharged by operation of the supplier. The supplier has multiple rollers disposed separated in the feed direction of the sheet; a rotation driver configured to rotationally drive the multiple rollers; and a roller support supporting the rollers in a direction to and away from the support surface. The sheet placed on the support surface contacts at least one of the multiple rollers and is fed to the discharger by displacement of the roller support.

A sheet processing apparatus includes a conveying roller that conveys a sheet, a processing tray on which the sheet from the conveying roller is loaded, a reference stopper provided at one end of the processing tray, a return paddle having an elastic piece for transferring the sheet from the conveying roller to the reference member, and a roller arm that moves the return paddle in the sheet thickness direction at a predetermined moving rate according to the number of sheets loaded on the processing tray. The moving rate of the roller arm is reduced as the number of sheets loaded on the processing tray is increased. With this configuration, aligning property of even a wavy sheet can be suppressed from being deteriorated at sheet loading.

A curl straightening device includes an endless belt, a curl straightening roller, a nip width adjusting mechanism, and a guide member. The curl straightening roller makes pressure contact with an outer peripheral surface of the endless belt, forming a nip portion, and straightens curl of the sheet which passes through the nip portion. The nip width adjusting mechanism moves the curl straightening roller in a direction away from or close to the endless belt so as to change a nip width. The mechanism includes a supporting holder of the curl straightening roller, and a rotationally moving portion that rotationally moves the roller supporting holder for moving the curl straightening roller. The guide member includes a pair of hanging members that are hung from both ends of the curl straightening roller so as to keep the guide member in constant position and posture relative to the curl straightening roller.

The curl straightening device includes supporting rollers, an endless belt, a curl straightening roller, and a contact member. The supporting rollers are disposed rotatably about a shaft extending in a direction orthogonal to a conveying direction of the sheet. The endless belt is stretched across the supporting rollers, and circulates in the conveying direction. The curl straightening roller makes contact with an outer peripheral surface of the endless belt between the supporting rollers so as to form a nip portion, and straightens curl of the sheet which passes through the nip portion. The nip portion is shaped so that the endless belt curves along a peripheral surface of the curl straightening roller. The contact member is disposed to oppose a center portion of the curl straightening roller in an axial direction, and makes contact with the curl straightening roller so as to prevent deformation of the curl straightening roller.

A presentation device for presenting a ticket from a printer includes first and second reels, a ticket holder and a housing component. In operation, the first reel contacts a first side of the ticket, and the second reel contacts a second side of the ticket opposite to where the first reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first reel, the second reel and the ticket holder are secured in the housing component. The housing component is pivotable about a rotating axis and has a supporting notch that supports the second reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough between the first guide edge surface and the second guide edge surface.

A sheet discharge apparatus includes: a discharger that discharges a sheet; a loading part on which the sheet discharged from the discharger is loaded; an abutment member that abuts against a rear end of the sheet in a direction of discharging to align the sheet loaded on the loading part; a pull-back member that performs a pull-back operation by contacting with the sheet discharged from the discharger to pull back the sheet toward the abutment member; and a hardware processor that controls the pull-back member. The hardware processor performs the pull-pack operation on a sheet bundle when determining that the sheet bundle bound by a binder is discharged from the discharger.

There is an apparatus for transferring a thin-film element, the apparatus comprising: a belt-type stamp; at least one support roller configured to allow a movement of the stamp; a first-stage roller system including at least one first-stage roller, wherein the first-stage roller is configured to allow thin-film elements attached to a first substrate to be picked up from the first substrate and to be attached to the stamp, wherein; and a second-stage roller configured to allow the thin-film elements attached to the stamp to be picked up from the stamp and to be printed onto a second substrate, wherein a curvature radius of the first-stage roller and a curvature radius of the second-stage roller are different from each other.
