ABSTRACT:
A watt-hour meter or other visual read-out apparatus which may also be read electrically through the use of a plurality of code discs and a photoelectric sensing device in spaced juxtaposition with the back sides of the discs. The sensing device is supported by a cable-controlled carriage which reciprocates back and forth in a direction parallel to the discs under the control of a bidirectional electric motor. A pair of stop members are located at opposite ends of the path of travel of the carriage for causing the motor to reverse direction as the carriage contacts one of the stop members.
