Abstract
An apparatus for placing in order the servicing sequence of storey calls of an elevator system, comprising storage elements for storing the storey calls, storage transmitter means for controlling the storage elements, a scanner for scanning the storage elements, and a respective further storage element operatively associated with each storey being serviced. Each such further storage element has a first input connected with the related storage element serving to store a storey call and its output is connected by means of a logic circuit with a blocking device blocking infed and stored storey calls during a servicing period corresponding to at least one revolution of the scanner. A second input of each such further storage element is connected with the output of a release device freeing the blocked storey calls after completion of a servicing period in order to accomplish storey servicing during the following servicing period. A first input of the release device is connected with an output of the scanner delivering information at the start of a scanner revolution and its second input with the output of the blocking device and with a switching device controlling the scanner drive. Release of the stored storey calls and thus initiation of a new servicing period first is accomplished when there appears at the output of the blocking device information signaling the completion of the storey calls released during the preceding servicing period.
