    • In a stapling system with a power driven stapler unit for stapling sheets together by clamping the sheets together with a clamper and driving a staple into the sheets with a staple driver while the sheets are clamped, and clinching the legs of the staple with a clincher, sequentially in that order; a single flexible cable with internal bights thereof operatively connecting with the clamper, the staple driver and the clincher, and with a free portion of the cable extending from the stapler unit and pulled with increasing movement and tension to provide the sole actuating power for the stapler unit wherein sequentially coupling pulleys engaged by the internal bights of the single flexible cable, and movement stops and/or resistance springs of different resistance forces, respectively operatively associated with the clamper, the staple driver and the clincher actuate them in that order, and wherein paired pulleys are arranged to multiply the forces available for the stapling from the cable tension.
    • 在具有动力输入装订器单元的装订系统中,用于通过将片材与夹持器一起夹紧来将片材装订在一起,并且在夹持片材的同时用钉子驱动器将钉子驱动到片材中,并用钳子夹紧订书钉的腿部, 按顺序依次; 单个柔性电缆,其内部弯头可操作地与夹持器,缝钉驱动器和敲弯器连接,并且电缆的自由部分从订书机单元延伸并且随着运动和张力的增加而拉动,以为订书机提供唯一的致动力 单元,其中顺序地联接由单个柔性电缆的内部弯头接合的滑轮,以及分别与夹持器,缝钉驱动器和敲弯器分别操作地相关联的不同阻力的移动止挡件和/或阻力弹簧,并且其中 配对的滑轮布置成将可用于缝合的力与电缆张力相乘。
