PURPOSE: To prevent encoded running from being released by a function of standing-by on a main story floor during inputting the encoded code in an elevator operated by the encoded code.

CONSTITUTION: When a can call button for a specified story among car call buttons 1A-6A is depressed, then a detecting means A detects the input of an encoded code during the operation of the encoded button. Next, when encoded codes are inputted by the car call buttons 1A-6A, An encoded call registering means B registers the car call on a specified story to give encoded operation to the car by an operating apparatus C. On the other hand, when the detecting means A is operated during the operation of the encoded button, a stand-by releasing means E is operated to command to a stand-by-on-main-story commanding means D so that the car is prevented from shifting to the stand-by-motion on the main story.
