摘要:
The present invention relates generally to tabs that activate shredder safety interlock switches. Specifically, this invention discloses a break-resistant tab which can readily activate a shredder safety interlock switch. The disclosed tab is comprised of a tab extension with at least one flexing member or spring which allows for limited flexibility.

An auto electricity breaker includes a breaker switch, an energy storage device driven by a cutting blade ensemble, a variable gear set driven by the energy storage device, a trigger driven by the variable gear set to turn on the breaker switch, and a starting switch for restoring the trigger. The energy storage device stores energy concurrently during the operation of the cutting blade ensemble. When the cutting blade ensemble stops operation, the variable gear set is driven to operate. When the variable gear set operates to a certain extent, the trigger takes action to turn on the breaker switch. The breaker switch breaks the electrical power of the shredder to stop its operation. The user can turn on the starting switch for restoring the trigger and thus turn on the power of the shredder again for normal operation. The breaker then resumes its auto electricity breaker function.

An improved laminator is disclosed. A guiding outlet is provided above or below the front feeding inlet of the laminator, so that both the guiding outlet and the feeding inlet face the user. This reduces the space required for operating the laminator.

A heating element that can maintain a laminator at a predetermined working temperature is disclosed. A low-power heating filaments and a high-power heating filaments are sandwiched between insulators. The high-power heating filaments are shut down once it is heated to a predetermined temperature. The low-power heating filaments are then turned on to maintain a constant temperature. When the temperature drops below a predetermined temperature, the low-power heating filaments are shut down and the high-power heating filaments are turned on to heat up the laminator. The temperature is thus maintained within a predetermined range through such cycles.

An improved compartment of shredder for receiving piled-up sheets, including: a pair of longitudinal movable paper press rollers applying pressure to the piled-up sheets continuously; a compartment for receiving piled-up sheets; a pair of rollers capable of feeding paper continuously and paper shredding blades located beneath the paper feed rollers; wherein, the compartment bottom is provide with a narrower platform next to the paper feed rollers, the platform being formed with a paper entry and Y-shaped guide grooves at a center thereof, and the platform being provided at two opposing outer edges with compartment bottom surfaces inclining downwards, the bottom surfaces then extending vertically upwards to form compartment sidewalls, whereby when the piled-up sheets are placed in the compartment, the paper would form opposing upward curvatures along with the inclination of the compartment bottom surfaces in accompaniment with a force applied to the paper at specific locations by the longitudinal movable paper press rollers, thereby facilitating the paper feed rollers in dragging the paper downwardly into the paper shredding blades in a smooth manner.

A transporting conveyor for continuously laminating plural objects has a transporting belt and several resilient tabs disposed thereon in parallel. After objects to be laminated are disposed in lamination pouch films, they are held and positioned by the resilient tabs. The transporting belt slowly moves and sends the objects to be laminated and held on the resilient tabs into the laminator, reducing time required for laminating plural objects.

This specification discloses a variable protection board that can change the width of the opening of a paper shredder. A sliding block is disposed on one side of the paper shredder opening to change the relative position between the sliding block and the opening. When the shredder is operating, the opening width thereof can be changed to a narrower default state, preventing the user from putting fingers into it and getting hurt. To back the paper out, the opening width of the shredder is changed to a wider default state for the user to take out the paper. A switch can be disposed along the stroke of the sliding block. When the sliding block goes to the state with a wider opening width for backing out paper, the shredder is powered off at the same time to shut down the running motor and thus protect the safety of the user.
摘要:
A rocking wastebasket or bin for paper shredder, including a machine body having cutting blades therein and a wastebasket or bin for containing paper chips, wherein the wastebasket or bin has a section of planar placement surface at a bottom thereof, and the planar placement surface is provided with arcuate faces between the planar placement surface and engagement portions at the bin walls, such that when the user rocks the wastebasket or bin forwards and backwards, or sideways, the chips in the chip mountain accumulated beneath the discharge port at the cutting blades can be spread outwards, so as to increase the space for receiving the paper chips in the wastebasket or bin, and to prevent the “chip mountain” from impeding smooth falling of subsequent paper chips, thereby eliminating the defects of affecting overall operative functions of the paper shredders.
