Abstract: A train printer cartridge and print slug arrangement having a closed loop guide track for non inter connected print slugs freely slidable in the guide track and each having a single drive tooth on each side of the slug, the teeth meshing with notched drive wheels. The track arrangement permits the slugs to move from abutting contact whilst meshing with the wheels and also enables transformation of angular motion around the wheels to the straight line motion for advancing to the printing section to be completed before the slug leaves the drive wheels.

Abstract translation: 一种列车打印机墨盒和打印芯片布置，其具有用于不相互连接的打印段的闭环导轨，所述打印块在导轨中可自由滑动，并且每个在所述塞的每一侧具有单个驱动齿，所述齿与切口驱动轮啮合。 轨道装置允许s s从邻接的接触件移动，同时与车轮啮合，并且还能够使车轮周围的角运动转化为直线运动，以在刀片离开驱动轮之前前进到打印部分以完成。

Abstract: In a document feeding apparatus which separates an edge of a document from a stack prior to feeding the separated document, a document thickness sensing device is employed to detect whether more than one document edge has been separated or whether there has been a failure to separate an edge. The sensing device consists of a finger which is moved over the separated part of a document as it lies on a reference surface. The finger carries a magnetic insert which is magnetically coupled to an inductor so that the displacement of the finger alters the inductance of the inductor.
