    • A punchcode reader is provided for reading data encoded in a punchcode hole array on a dosimeter. The dosimeter falls through a passage in the reader containing photosensor detectors disposed along the passage which provide output signals to a microprocessor. The signals are processed to determine the orientation of the dosimeter in the reader, the location and state of punchcode holes in a two row array thereby decoding the encoded data. Multiple rate of fall calculations are made, and if appropriate matching of the punchcode array is not obtained in three tries, an error signal is outputted to the operator. The punchcode reader also provides for storage of data from multiple dosimeters passed through the reader, and for the output of decoded data to an external display or a computer for further processing.
    • 提供了一种打码编码读取器,用于读取在剂量计上编码在打孔代码孔阵列中的数据。 剂量计通过包含沿着通道设置的光电传感器检测器的读取器中的通道落下,其向微处理器提供输出信号。 处理这些信号以确定读取器中剂量计的方位,两行阵列中的穿孔码的位置和状态,从而对编码数据进行解码。 进行多次跌落计算,并且如果在三次尝试中不能获得打孔代码阵列的适当匹配,则向操作者输出误差信号。 打码读取器还提供用于存储通过读取器的多个剂量计的数据,以及用于将解码的数据输出到外部显示器或计算机用于进一步处理。

    • A system for perforating record media by the use of ''''stationary'''' perforating equipment, i.e., in which the punches do not move in the direction of movement of the record media. The record media is transported through the perforating equipment by frictionally engaging the surfaces of the record media with a plurality of continuously driven rollers. The continuous frictional drive applied to the record media is maintained during the perforating of the record media to obtain high throughput rates. The frictional drive rollers are skewed so as to urge the media against an inturned flange on one side of the media supporting surface. A photoelectric sensor senses the position of the record media for actuating the punches only when media is present at the perforating station.
    • 一种通过使用“静止”穿孔设备对记录介质进行穿孔的系统,即冲头不会在记录介质的运动方向上移动。 记录介质通过与多个连续驱动的辊摩擦地接合记录介质的表面而穿过穿孔设备。 在记录介质的穿孔期间,保持应用于记录介质的连续摩擦驱动,以获得高吞吐率。 摩擦驱动辊是偏斜的,以便将介质推压在介质支撑表面的一侧上的内壁凸缘上。 光电传感器仅在存在于穿孔台处的介质时感测用于致动冲头的记录介质的位置。
