摘要: Apparatus for scanning the relative position of a preselector counter mechanism which includes a plurality of digital discs having radial cams rotated in accordance with the setting of a preselected numerical value on the counter, with each of the radial cams being provided with a scanning arm adapted to initiate a switching operation upon reaching a preselected stage of the counter mechanism, is provided with a plurality of counter wheels each adapted to be set to a pre-selected value with an analogue metering value cam in the shape of an Archimedean spiral being affixed to each of the counter wheels. Each of the counter wheels and the metering value cams is arranged to represent a decade of a decimal system numerical value. Indexing pinions gear each of the counter wheels and the metering value cams with those representing a next adjacent decade. Multiarmed spring actuated swivel levers scan the metering value cam in sequence by decades after release from a ready position from a higher decade to a next lower decade. The device operates a switching shaft which is connected to control a valve or similar mechanism and the switching shaft is formed with stepped levers interacting with the swivel levers. The swivel levers include an extension arm operating as a scanning arm for scanning the metering value cams and with another extension arm provided with functional plateaus for effecting release by decades of the swivel levers into the scanning position, with the other extension arm operating to release the stepped levers for effecting a stepped control function of the switching shaft.
