Abstract

Disclosed herein is a guide assembly and stapling support for improving the latitude of a stapler head manufactured by Max Co. Ltd., Tokyo Japan. The specific feature is to provide improved stapling of small sets, such as only two light light weight sheets. The present system prevents sheets of light weight paper from buckling when pushed against the stapler's switch actuator, and provides said paper with sufficient beam strength to move the switch actuator into its operating position to start a stapling cycle. This is accomplished here by a guide assembly consisting of a spring loaded guide plate, an insert hinge, and guide, all mounted to the stapler head. The specific parts that comprise this embodiment are presented in an exploded view in Fig. 1 as they appear prior to their placement in the stapler head. Fig. 1 includes both a front view and a side view respectively of the guide plate 22, the insert hinge 20, and the guide 34.

GUIDE ASSY-STAPLING SUPPORT(Cont'd)

Disclosed herein is a guide assembly and stapling support for improving the latitude of a stapler head manufactured by Max Co. Ltd., Tokyo Japan. The specific feature is to provide improved stapling of small sets, such as only two light light weight sheets. The present system prevents sheets of light weight paper from buckling when pushed against the stapler's switch actuator, and provides said paper with sufficient beam strength to move the switch actuator into its operating position to start a stapling cycle. This is accomplished here by a guide assembly consisting of a spring loaded guide plate, an insert hinge, and guide, all mounted to the stapler head. The specific parts that comprise this embodiment are presented in an exploded view in Fig. 1 as they appear prior to their placement in the stapler head. Fig. 1 includes both a front view and a side view respectively of the guide plate 22, the insert hinge 20, and the guide 34.

Describing now in further detail the embodiment with reference to the Figures,there is shown in Fig.2 a document output portion of one xerographic printing machine 10 to illustrate by way of one example, a stapling unit including the disclosed guide assembly and stapling support.

In this example, a separate convenience stapler unit 12 is shown as a integral part of the overall printing machine 10. As part of the document feeder output tray 11, the convenience stapler unit 12 is ideally mounted on top of the printing machine 10 and close to the location where copied documents that require stapling are collected. The convenience stapler is also oriented in a vertical position thereby allowing an operator easy access to the stapling operation. A slot 12a in the stapler cover 14 creates the sheet insertion entrance that accommodates a maximum document set of up to, for example, 50 sheets of stacked paper. Some of the individual sheets may be curled thus creating a larger than normal stack width when compared to the normal width of a perfectly flat stack of 50 sheets. Therefore slot 12a has a wider opening at the top for ease of manually inserting a single maximum allowable document set consisting of an abnormal stack width caused by various degrees of curling in the individual sheets. The slot 12a then narrows or ta...
