    • A visually and electronically readable motor driven register has a plurality of dependently rotatable, coaxial, incrementally positionable, number wheels which each carry a movable electrode fixed in a predetermined position relative to the numbers on each wheel. Adjacent each movable electrode is inserted a fixed plate which carries a plurality of stationary electrodes, each corresponding to a number on the wheel and disposed circumferentially around a stationary main electrode which is capacitively coupled to the movable electrode. When a number on a wheel is visually readable, the movable electrode will be positioned so as to be capacitively coupled only to the stationary electrode corresponding to the readable number. A microprocessor provides pulses sequentially to the stationary electrodes of each wheel, and checks for a coincident processed output from the main electrode of the first wheel. If there is a processed output indicating capacitive coupling between stationary and movable electrodes, the microprocessor retains the electrode number indicative of the readable number of the first wheel and checks for a coincident processed output from the main electrode of the second wheel. When all the wheels have been read, the first wheel is again checked; if all the wheels have not been able to be read, the microprocessor will activate the motor to move the wheels until they can all be read.
    • 视觉和电子可读的电动机驱动的寄存器具有多个可依赖地旋转的,同轴的,递增定位的数字轮,每个轮分别携带固定在相对于每个车轮上的数字的预定位置的可动电极。 相邻的每个可移动电极插入固定板,该固定板承载多个固定电极,每个固定电极对应于车轮上的数字,并且围绕电容耦合到可动电极的固定主电极周向设置。 当车轮上的数字在视觉上可读时,可动电极将被定位成仅与对应于可读号码的固定电极电容耦合。 微处理器依次向每个车轮的固定电极提供脉冲,并且检查来自第一车轮的主电极的重合处理的输出。 如果存在指示固定电极和可移动​​电极之间的电容耦合的经处理的输出,则微处理器保留指示第一车轮的可读号码的电极号码,并检查来自第二车轮主电极的重合处理输出。 当所有车轮都被读取时,再次检查第一个车轮; 如果所有的车轮都无法读取,微处理器将启动电机以移动车轮,直到它们全部被读取。
