A sheet postprocessing apparatus includes an inlet guide, a perforation device, and a collection tank. The inlet guide includes an upper guide and a lower guide. The perforation device is located downstream of the inlet guide in a sheet transport direction. The collection tank is located on a lower side of the perforation device. The lower guide is supported so as to pivot in an up-down direction, about an end portion in a sheet width direction. The collection tank is removably supported, by sliding in the sheet width direction. The lower guide includes a lever located on the other end portion in the sheet width direction, and configured to disengage the lower guide from the upper guide. The collection tank includes a restriction device opposed to the lever and configured to restrict pivotal movement of the lower guide, when the collection tank is attached to the perforation device.

A cutter unit according to an embodiment of the present disclosure is configured to cut recording paper that is conveyed. The cutter unit includes a movable blade that can advance toward or retract from the recording paper and is configured to cut the recording paper when the movable blade advances. The cutter unit also includes a peeling mechanism including a contacting portion configured to move in a direction opposite to a direction of advancement or retraction of the movable blade and contact the recording paper.

An image forming apparatus includes: a conveyor conveying a sheet medium; an image forming part forming an image on the sheet medium; a cutting part; a signal outputting part outputting a state signal; a reporting part; and a controller. The controller executes: an image forming process of conveying the sheet medium by the conveyor and forming the image on the sheet medium by the image forming part, and a cutting process of moving the cutting part. In a case where the sheet medium has not been cut even though the cutting process was executed during image formation on the sheet medium in the image forming process, the controller continues the image formation without interruption and causes the reporting part to report information regarding a failure of cutting of the sheet medium.

An articulating paper dispenser comprising: an articulating-paper-roll retainer with a housing that defines an articulating-roll-receiving interior and a paper outlet; a blade arm extended from the housing and defining a finger-receiving pincer zone between the housing and the blade arm, the blade arm mounting a paper-cutting blade that is oriented to cut articulating paper that extends, in use, across a mouth gap that opens into the finger-receiving pincer zone and is defined between the paper outlet and the paper-cutting blade.

The invention relates to a cutter for self-adhesive linerless endless tape labels, said cutter comprising a transport roller, which is rotatable about an axis of rotation, and a blade unit that comprises a blade carriage, which is linearly travelable in parallel with the axis of rotation of the transport roller, and a cutting blade that is rotationally fixedly held at the blade carriage and that is directed in the direction toward the transport roller, wherein the endless tape labels can be led between the transport roller and the blade unit. The blade unit comprises a blade holder that forms an assembly with the cutting blade, in which assembly the cutting blade projects with a fixed overhang over the blade holder, with the assembly being displaceably fastened to the blade carriage and a spring device, in particular a compression spring, being provided that preloads the assembly into an extended position.

The present invention refers to the apparatus for storage and dispensing foil from the roll, and also to the wall attachment for placement of multiple dispensers in vertical dispenser system for rolled materials, where two side walls and one back wall of dispenser's body, perpendicular to the floor, enclose the storage space for the material from three sides, while fixedly attached cutting assembly provides the fourth wall. The elongated slot located close to the back wall in the floor of the dispenser base interacts with gravitationally working pivoting latch of the mounting wall frame in the vertical dispenser system to secure placement of installed apparatus on the wall frame. Top rotatable attached to the side walls of the container, while lifted from horizontal position by handle tab, reveals the free end of foil on top of the shroud that remains ready for picking and pulling from the roll in container anytime the top is lifted from horizontal position and then cut by pulling farther the unwound foil while bottom edge of top's body tab pushes foil below the cutting blade, and also frictionally holds the foil between shroud and top's body tab, therefore the foil, pulled farther, engages with serration of the cutting blade due to the intervening position of the said blade in relation to pulling direction.

A film winding machine includes a main body and an automatic cutting-off roll-replacing mechanism. The main body has a winding reel, a standby reel, and an intermediate redirecting reel. The automatic cutting-off roll-replacing mechanism has a supporting frame which is fixed to the main body. The first swing unit is rotatably connected to the supporting frame along a forward direction. The first pressing roll abuts against one side of the standby reel. The second swing unit is rotatably connected to the first swing unit. The second pressing roll contacts the other side of the standby reel. The slicing unit is used to cut the film. The film is wound on a new standby reel, so as to complete tasks of automatically cutting-off and roll-replacing.

A desktop adhesive tape binding and cutting platform includes a fundamental base provided with a connecting plate. The fundamental base is pivotally provided with a rotating shaft for installing an adhesive tape roll thereon. A binding platform is connected with the free end of the connecting plate, and a cutting portion is connected with the binding platform and has its free end provided with a cutting member and a fixing member. Thus, during binding operation, the desktop adhesive tape binding and cutting platform of this invention is able to cut off adhesive tape via the cutting member and meanwhile fix the adhesive tape in place via the fixing member.

The present invention discloses a tape dispenser which includes a body having a downward facing concave space at a bottom thereof, a cutting blade mounted to the body and positioned in the concave space with an cutting edge recessed in the concave space, a groove member being able to move vertically between a first and second location, at the first location, the groove member being partially submerged in the concave space and pocketing at least a portion the cutting blade for cutting a piece of tape, at the second location, the groove member being downwardly away from the bottom of the body for threading a piece of tape through a gap formed between the groove member and the bottom of the body, a side plate attached to an end of the groove member, the side plate being slidably accommodated in a hollowed space formed inside the body, the side plate having a slot for retaining a spring to urge the side plate to slide downwardly resulting in the groove member to move from the first location to the second location, and a stopper situated within the slot and at an upper end of the spring, the stopper being fixed to the body and preventing the side plate from being completely pulled out of the hollowed space.
