ABSTRACT:
A cage position display apparatus for an elevator having a machine room controller including a first converter having a memory for converting binary signals representing positions of a cage into display codes corresponding to a particular floor arrangement of a building in which the elevator is installed, a cage position display device including a second converter for converting the display codes into corresponding driving signals and display unit operated on the basis of the driving signals for displaying the position of the cage, and a plurality of signal lines connecting the machine room controller to the cage position display unit to transmit the display codes therebetween. Therefore, display patterns can be readily altered merely by changing the contents of the memory in the machine room controller.
