    • A stitcher system includes a stitcher mechanism for stitching collations of documents and adapted to form stitches from a conductive wire moved into the stitcher mechanism. A non-conductive spool is mounted for rotation on a spindle. A conductive wire is wound on the non-conductive spool. The conductive wire has a tail end adjacent to the non-conductive spool and a lead end remote from the spool. The spool rotates when the conductive wire is moved into the stitcher mechanism to provide conductive wire to be used by the stitcher mechanism to form stitches. A sensing circuit is provided with a circuit path that includes the conductive wire wrapped on the non-conductive spool and a conductive member mounted to engage the wire. The sensing circuit path becomes open when the conductive wire is not wrapped on the non-conductive spool to thereby detect an out of wire condition.
    • 缝合器系统包括缝合器机构,用于拼接文件的排列,并适于从移动到缝合器机构中的导线形成线迹。 安装非导电线轴用于在主轴上旋转。 导线缠绕在非导电线轴上。 导线具有与非导电线轴相邻的尾端和远离线轴的引线端。 当导线移动到缝合机构中时,线轴旋转以提供要由缝合机构用于形成线迹的导线。 感测电路设置有包括缠绕在非导电线轴上的导线和安装成接合线的导电构件的电路路径。 当导线未缠绕在非导电线轴上时,感测电路路径变为开路,从而检测出脱线状态。
