A feeding unit includes a paper feeding tray, a lifter, a feeding roller, a guide plate, and a handling portion. The lifter can displace paper in the paper feeding tray in a +B direction. The guide plate guides a downstream end of the paper lifted by the lifter in a +A direction toward the feeding roller. The handling portion handles the paper toward the feeding roller. The guide plate forms a frontage through which the paper can pass between the guide plate and an outer peripheral surface of the feeding roller, and is provided so that a size of the frontage can be adjusted. The handling portion is provided integrally with the guide plate.

A feeding unit includes a retard roller, a first holder, a second holder, an accommodating portion, a pressing portion, a second pressing portion, a release lever, and a second restricting portion. The accommodating portion accommodates the second holder. The second pressing portion presses the second holder in a +Z direction. The release lever restricts the movement of the second holder in the +Z direction. The second holder is provided with a plurality of restricted portions in a Y direction and a +A direction, respectively. The second restricting portion restricts the movement of the second holder in a −Z direction. The second restricting portion has a restricting surface. The restricting surface is provided in the accommodating portion and is configured to come into contact with the plurality of restricted portions.

A stripper assembly can include a feed wheel, a stripping tire, a drag clutch, and first and second stripping elements. The feed wheel and stripping tire can be mounted for rotation in clockwise (CW) and counter-clockwise (CCW) directions and can contact one another to define a nip through which papers are directed. The drag clutch can be interposed between the stripping tire and the shaft it is mounted upon. The first and second stripping elements can be positioned on the shaft of the stripping tire on opposite sides of the nip. Each of the stripping elements can be configured and positioned to engage papers passing through the nip. The drag clutch is not interposed between either of the first and second stripping elements and the shaft of the stripping tire.

An electric stretch film dispenser includes a frame and a power unit. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly provided with a film mounting unit and a film dispensing unit. The film dispensing unit has a first roller and a second roller. The first roller is connected with a first power drive unit. The first power drive unit is configured to drive the first roller to rotate. When in use, the film of a film roll is pulled due to different rotational speeds of the first roller and the second roller. Thereby, the electric stretch film dispenser can automatically generate tension when used, so it can be used to pack articles at different heights. The electric stretch film dispenser facilitates the application of the film and increases the tension of the film.

A sheet feeder includes a separator to separate an uppermost layer from a bundle of sheets stacked on a sheet stacker, a conveyor to convey a sheet of the uppermost layer one by one along a sheet conveyance path, and a first air blowing port and a second air blowing port disposed along the sheet conveyance path, to blow air upstream in a sheet conveyance direction. The second air blowing port is disposed downstream from the first air blowing port.

According to one embodiment, an image forming apparatus includes a support shaft, a connecting member, and a detachable member. The support shaft extends in a first direction. The support shaft includes a protrusion. The protrusion protrudes in a second direction orthogonal to the first direction. The connecting member is formed of an elastic material. The connecting member interposes the protrusion therebetween. The connecting member is connected to the support shaft to surround an outer periphery of the support shaft. The detachable member is detachably connected to the support shaft via the connecting member.

A tension information acquisition device acquires tension of a wire electrode and is provided with: a back tension adjustment unit that makes the magnitude of back tension of the wire electrode zero; and an acquisition unit that acquires tension information indicating the tension on the basis of a disturbance estimate value or output torque of a feed motor when the magnitude of the back tension is zero.

A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller, with a motor geared to the drive roller. An automatic separator device is provided, wherein the drive roller conveys a leading lottery ticket to a separation position such that a line between the leading ticket and an adjacent ticket is presented to the separator device. The separator device includes a shuttle that travels in a linear path along the line, the shuttle having a head that engages and separates the leading ticket from the adjacent ticket along the line. A bi-directional drive mechanism moves the shuttle back and forth along the linear path.

A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller. A motor is geared to the drive roller and is switchable between a convey mode wherein the drive roller engages and conveys a leading ticket to a separation position and a brake mode wherein the motor provides a reverse retarding force to the drive roller to brake the drive roller against an attempted reeling of the lottery tickets. from the dispensing unit. A controller switches the motor between the convey and brakes modes such that in the brake mode, power to the motor is interrupted and windings in the motor are short-circuited.
