The roll support assembly may have a linkage arm and/or a roll support arm. Positions of the first and second mandrels relative to the dispenser's opening can be switched by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. A method for switching positions of rolls in the web material dispenser is also provided.

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

According to one embodiment, a sheet cassette includes a sheet placing portion. The sheet placing portion can rotate around a rotation shaft while placing a sheet of a placeable maximum size in a sheet placing area to be flat. The rotation shaft extends to be perpendicular to a discharge direction and a gravity direction of the sheet. The rotation shaft is disposed between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

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 adhesive body delivery device includes a main body, a turning portion, and a press-bonding portion; the turning portion is mounted to the main body to be relatively turnable around a first turning axis A1; the press-bonding portion is mounted to the turning portion at a predetermined mounting position, and is turnable in conjunction with the turning portion; the press-bonding portion is configured to deliver an adhesive body at a predetermined delivery position P, and is configured to stick the adhesive body to a target object while press-bonding the adhesive body; a predetermined distance D is ensured between the first turning axis A1 of the turning portion and the mounting position; and the press-bonding portion is configured to turn around a second turning axis A2 passing through the mounting position and being parallel to the first turning axis A1.

Provided is a printing apparatus for performing printing on a sheet drawn out from a roll including: a roll holding unit configured to hold the roll; a support unit configured to rotatably support the roll holding unit; a core portion provided to the roll holding unit and configured to be inserted into a hollow portion of a core pipe of the roll from an end portion of the core pipe to extend along an axis of the core pipe; a contact member provided to the core portion and configured to be put in contact with an inner wall surrounding the hollow portion of the core pipe; and a cam member disposed inside the core portion and configured to pivot to a first position where the contact member is pressed onto the inner wall and to a second position where the contact member is retracted from the inner wall.

A sheet feeding device includes a feeding roller pair, a first guide, a door including a second guide and rotatable between a first direction and a second direction opposite to the first direction through first to third positions, a damping mechanism, and an engaging portion including an elastic member. A first resisting force is set so that moment acting around a shaft by a self-weight of the door is larger than the first resisting force of the damping mechanism when the door is positioned between the second position and the third position. A resultant force of the first resisting force of the damping mechanism and a second resisting force of the elastic portion is set so that the moment acting around the shaft by the self-weight of the door is larger than the resultant force when the door is positioned between the second position and the third position.

An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

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 sheet alignment apparatus includes a supporting portion configured to support a sheet, a first alignment member configured to abut an end portion in a first direction of the sheet supported by the supporting portion and align a position of the sheet in the first direction, a first moving unit configured to move the first alignment member in the first direction, a second alignment member configured to abut an end portion in a second direction of the sheet supported by the supporting portion and align a position of the sheet in the second direction, the second direction being perpendicular to the first direction, and a second moving unit configured to move the second alignment member in the second direction, wherein the first moving unit is disposed below the supporting portion, and wherein the second moving unit is disposed above the supporting portion.
