Publication number: 20110062210Abstract: A stapler comprises a mechanism to first fully drive staples into sheets of materials, e.g., paper, and only then to fold over the legs of the staples. This results in a flat clinch and very few crumpled staples.

For this reason, the loading/unloading of the staple cartridge can be done without any hitch. The staple feeding mechanism only requires a necessary minimized number of components and so is simple in structure. Thus, the stapler can be provided at low cost. Particularly, the driving shaft necessary to cause the magazine to make a reciprocating motion is also used as a fulcrum member, thus requiring no new component. This further reduces the number of necessary components and also contributes to space saving.Type: ApplicationFiled: April 16, 2009Publication date: October 29, 2009Applicant: MAX CO., LTD.Inventor: Futoshi KAMEDA

Patent number: 7311238Abstract: An electric stapler comprises an enclosure, a motor, a power transmission device, a working arm pivotally attached to the enclosure, a magazine receiving a plurality of staples and a clinching assembly. A guide device is mounted upon the working arm and rotating therewith. The guide device defines a guideway therein. The magazine is slidably engaged with the working arm. The clinching assembly combines a blade support and a blade, both received in the guideway of the guide device and movable therein. The blade support is engaged with the lever. The power transmission device transmits power and torque from the motor to the clinching assembly. The guide device is mounted upon the working arm and rotates therewith, the blade support slides in the guideway and simultaneously rotates with the guide device, thereby no interferences between the blade support and guide device occurs.Type: GrantFiled: December 9, 2005Date of Patent: December 25, 2007Assignee: Ringsun (Shenzhen) Industrial LimitedInventor: Yingming Liu
