ABSTRACT:
A cage position detecting apparatus operates the data for the present position of the cage by a computer. The data for the final floor memorized in a read only memory are used as the data for the present position when the cage stops at the final floor to output a signal from a position detector placed in a hatchway. The cage is run to the final floor when the position detector corresponding to the final floor does not output a signal in the condition that the operated data for the present floor indicates the final floor. The operated data for the present position are memorized in a memory device actuated by the emergency power source to give the data being coincident with the actual cage position even though the operated data for the present position of the cage are changed by service interruption. The data for the condition of the cage just before the service interruption are memorized in the memory device. After releasing the service interruption, the memorized data for the condition of the cage are read out. If the cage is stopping at the time of the service interruption, the memorized cage position is given as the present cage position. If the cage is running at the time of the service interruption, the cage is forcibly run to the final floor and the data for the final floor memorized in the read only memory are memorized in the memory device to use the data as the operated data for the cage position. The operated data for the cage position deviated by the service interruption can be easily corrected. The operated data for the cage position can be always coincident with the actual cage position by the simple structure.
