There is provided a roller including: a shaft, and an elastic body portion that is provided on an outer peripheral surface of the shaft, in which the elastic body portion includes a plurality of first recessed portions which are provided on one side of the roller in a shaft mounting direction at intervals in a circumferential direction of the roller and each have a bottom portion, and a plurality of second recessed portions which are provided on the other side of the roller in the shaft mounting direction at intervals in the circumferential direction of the roller and each have a bottom portion, and in which each of the first recessed portions is positioned between the adjacent second recessed portions in the circumferential direction of the roller in the side view of the roller in the shaft mounting direction.

A roller includes a shaft, and an elastic body portion that is provided on an outer peripheral surface of the shaft, in which the elastic body portion includes an inner peripheral portion which becomes a shaft side, an outer peripheral portion which becomes an outer side with respect to the inner peripheral portion, a plurality of first connection portions which connect the inner peripheral portion and the outer peripheral portion, and a plurality of second connection portions which are provided in a space portion between the adjacent first connection portions and which partition the space portion into one side and the other side of the roller in the axial direction, and in which the first connection portion is inclined in the same direction in a peripheral direction with respect to a radial direction of the roller.

The disclosed devices and methods relate to a wire mesh dispensing device which improves the storage, transportation, dispensing, and rewinding of coiled materials, particularly in construction and building maintenance settings such as solar energy and pest mitigation. The dispenser resolves problems from coiled materials prone to expansion or unwinding, leading to storage challenges and safety risks. It features enclosing structures that prevent the coil from expanding beyond a set volume, side plates that keep the material layers aligned, and mechanisms for easy lifting and carrying. The device also includes a stable base with non-slip feet for secure placement on varied surfaces, rollers and a side plate to facilitate low-friction rotation for easy material dispensing in any orientation, and a rewinding mechanism for material take-up or coil tightening.

A medium processing apparatus for processing a medium ejected from an image forming apparatus includes a conveyor, a slit, a medium processing device, a stopper, and detectors. The conveyor conveys the medium ejected from the image forming apparatus. The slit communicates with an opening of a housing into which a medium is manually inserted from outside and includes a placement face on which the inserted medium is placed. The placement face has a first side and a second side orthogonal to the first side. The first and second sides are not parallel to a direction in which a side face of the housing extends. The medium processing device processes the medium conveyed by the conveyor or the medium placed on the slit. The stopper regulates edges of the medium along the first and second sides of the placement face. The detectors are disposed on the stopper to detect the medium.

A sheet discharging device has a discharge roller pair and a sheet discharge tray arranged selectively either in a first position where the sheet discharge tray is stowed along a side surface of an apparatus main body or in a second position where the sheet discharge tray, swung downward from the first position, protrudes beyond the side surface. The sheet discharge tray has a hook member holding, with one of rotation shafts of the discharge roller pair acting as an engagement shaft, the sheet discharge tray in the first position by engaging with the engagement shaft. As a result of the discharge roller pair being rotated with the sheet discharge tray located in the first position, an engagement releasing member fixed to the engagement shaft releases the engagement of the hook member with the engagement shaft, and the sheet discharge tray moves to the second position.

A sheet tray includes a first tray, a second tray, and a third tray. The second tray is configured to move between a stored position and an extended position, relative to the first tray. The third tray is pivotable about the pivot shaft between a first stowed position and a first extended position, relative to the second tray. One of the first tray and the third tray includes a columnar portion. The columnar portion protrudes toward the other of the first tray and the third tray in an area where, when the second tray is at the stored position and the third tray is at the first stowed position, the first tray overlaps the third tray in an orthogonal direction. The other includes a cutout shaped along a path where the columnar portion moves when the third tray moves from the first stowed position to the first extended position.

The rotational pin and the lock pin are laterally provided in the right and left first brackets that are fixed to the right and left side surfaces of the sheet loading tray respectively, and furthermore, the right and left second brackets are fixed to the right and left of the one side surfaces of the casing. When the sheet loading tray reaches the sheet loading position, the lock pin is made to enter the sheet loading tray lock groove formed on the right and left second brackets to thereby lock and hold the sheet loading tray at the sheet loading tray storage position, along with an action of rotating the sheet loading tray about the rotational pin fitting into the sheet loading tray support groove formed on the right and left second brackets from the sheet loading position to the sheet loading tray storage position.

The present invention provides a sheet feeding apparatus capable of feeding sheets at a proper position without a regulating member being bent even if a cassette unit is closed in a state in which a large volume of sheets are stacked. A large-volume feeding deck includes a non-reference-side regulating plate, an external casing plate, and positioning members, which are movable relative to the cassette unit.

There is provided a conveyance apparatus including: a main body including a drive source, and a conveyance portion to which a drive force is transmitted from the drive source; an equipped unit including a drive portion to which the drive force is transmitted from the drive source in the main body; a first gear provided in the main body and rotated by the drive force transmitted thereto from the drive force; a first gear holder provided swingably in the main body to support the first gear; a second gear provided in the equipped unit to transmit the drive force to the drive portion; a second gear holder provided swingably in the equipped unit to support the second gear; and a third gear supported by a connecting shaft connecting the first and second gear holders to engage respectively with the first and second gears.

There is provided a conveyance apparatus including: a main body including a drive source, and a conveyance portion to which a drive force is transmitted from the drive source; an equipped unit including a drive portion to which the drive force is transmitted from the drive source in the main body; a first gear provided in the main body and rotated by the drive force transmitted thereto from the drive force; a first gear holder provided swingably in the main body to support the first gear; a second gear provided in the equipped unit to transmit the drive force to the drive portion; a second gear holder provided swingably in the equipped unit to support the second gear; and a third gear supported by a connecting shaft connecting the first and second gear holders to engage respectively with the first and second gears.
