A paper scrap pushing structure of a paper shredder, including a rotating shaft, a paper pushing rod, and connecting rods, in which the rotating shaft is arranged under a paper outlet, and is in linkage with a paper shredder cutter shaft through a synchronous transmission device. The paper pushing rod is located on one side of the rotating shaft, arranged in the length direction of the rotating shaft in parallel and connected with the rotating shaft through the connecting rods. The distance from the paper pushing rod to the rotating shaft is smaller than the distance from the lowest portion of the paper shredder cutter shaft to the rotating shaft. When rotating, the rotating shaft drives the paper pushing rod to move in a circumferential direction through the connecting rods, removing paper scraps at the top of a paper scrap pile in a shredded paper waste bin.

The present invention relates to a document shredding apparatus having a document management apparatus. The present invention relates to a document shredder (10) comprising: a document feeder (121) formed on an upper portion of a case (120); a shredding portion (12) positioned below the document feeder (121) in the case (120) for shredding documents fed from the document feeder (121); and a collection box (125) for receiving waste paper shreds shredded by the shredding portion (12), wherein at least one document shredder (10) includes a server (20) which is located in a terminal for managing documents and networked to the document shredder (10) to manage the documents, wherein the server (20) is configured to store information and images of documents requested to be shredded from the document shredder (10), thereby safely managing discarded documents.

A small-form-factor high-security destruction machine for optical media has a weight empty of about 16.3 lbs and holds about 5 lbs of residue.

A paper shredder motor cooling assembly having a paper shredder motor coupled to a fan shaft, an enclosure surrounding the paper shredder motor and having selected input and selected output vents to control airflow to the paper shredder motor, a fan coupled to the fan shaft, communicating with the selected input vents or the selected output vents; when the paper shredder motor is operating, the rotor shaft turns the fan to generate a differential air pressure between the selected input vents and the selected output vents, removing heat from the motor. A duty cycle of greater than 15 minutes is obtained. The fan can be coupled to the motor by speed increasing gearing, attached to the cutter blade assembly, such that the fan turns faster than the motor. The fan also can be attached to the motor shaft. An input fan and an output fan can be used.

Provided is a positioning adjustment apparatus for a mobile device in scanning and photography, including a main body and a lifting unit. An object to be scanned is placed on the main body, and the mobile device placed on a carrier platform of the lifting unit can move up and down along with the lifting unit to adjust a distance between the mobile device and the object to be scanned. After scanning, a document is sent directly to a shredder. The invention also provides a wireless signal transmission to operate the mobile device for scanning or photography to meet various demands of the users.

A paper shredder support assembly for positioning a shredder above a receptacle includes a plate. A plurality of tubes is coupled to and extends from a bottom of the plate. Each tube comprises a plurality of nested sections so that the tube is selectively extensible. The plurality of tubes is positioned to support the plate over a receptacle. An opening is positioned in the plate. A shredder is positioned in the opening and is coupled to the plate. The shredder is configured to shred items that are inserted into the shredder so that shredded waste is expelled into the receptacle. A panel is selectively couplable to the plate to cover the opening.

A bag-closing device is disclosed which is capable of using general-purpose bags and which keeps the loss of capacity to the necessary minimum, and a shredder is provided which, even when shredded pieces of trash are stored in a bag, does not cause scattering of the shredded pieces of trash when closing the bag. The bag-closing device comprises one pair of horizontally facing winding shafts having tip parts for detachably holding a bag, which is open so as to allow objects to be put inside, at two facing opening edge parts from the outside of the bag, whereby the entire opening edge of the bag containing objects put therein is formed into a single horizontal roll-like shape by driving the one pair of winding shafts to rotate. In addition, the device may be provided with a cabinet, which allows a frame having one pair of winding shafts to be stored therein and to be pulled out therefrom together with a bag in an open state, and configured such that the one pair of winding shafts are restricted from rotating when the frame is pulled out from the cabinet whereas the one pair of winding shafts are allowed to rotate when the frame is placed in the cabinet. It is also feasible to construct a shredder having this bag-closing device installed below a shredding unit. In this case, preferably outer peripheral surfaces at the tips of the winding shafts are formed into a tapered shape.

A shredding device is provided comprising two shredding shafts arranged parallel to each other with shredding elements arranged thereon, wherein the shredding shafts are preferably rotatable mechanically synchronized to each other. A shaft-side coupling element is connected to a respective first end of the shredding shafts. The shredding device includes a housing with a housing-side coupling element is provided that can be coupled to the shaft-side coupling element. The shredding device includes a displacement device enabling displacement of the shredding shafts for decoupling and coupling the shaft-side coupling element from or to the housing-side coupling element.

The paper shredder simultaneously shreds both manually inserted sheets of paper and sheets of paper that are placed in an auto-feeder input tray. Immediately above the shredding mechanism the input path is bifurcated. One branch extends essentially straight up from the blades and leads to a manual input slot. A second branch extends at an angle towards the rear of the shredder where an auto-feed roller lies at the bottom of an auto-feed slot. When a stack of paper is placed into the slot, the bottom of the stack rests against the auto-feed roller which grasps the top sheet and pulls it under the roller. The roller then pushes the sheet down the angled throat where a curved surface bends the sheet downwards and into the shredding mechanism.

The present invention involves a collapsible and disposable container that is inserted into a paper shredder to catch the shredded paper fragments. The disposable container has a relatively narrow slot-shaped opening having a length less than the longest dimension of the top of the container. A pair of counter-rotating rollers is supplied to compact the paper fragments and feed them through the slot and into the waste container. Various sensor systems, some constructed from conductive ink are used with and within the disposable container.
