摘要： PURPOSE:To eliminate passenger's uncomfortable feelings by turning off a lamp which judges an abnormality based on a signal outputted from illumination abnormality detectors in a car of an elevator. CONSTITUTION:Illumination abnormality detectors 4a-4d in a car detect a change of luminous flux measured by photometers 3a-3d and transmit it as a lamp abnormality signal to an elevator controller 5. When a lamp 2a flickers, a lamp abnormality signal is outputted from the illumination abnormality detector 4a in the car with a contact 4aa in a closed condition to energize a lamp abnormality detection relay 9A coil. For this reason, a normally-closed contact 9Ab is opened and the lamp 2a is turned off. On the other hand, as for the energized condition of the lamp abnormality detection relay 9A coil, a normally-open contact 9Aa which is a self-hold contact is closed to form a self-hold circuit. The self-hold circuit is opened by operating a lamp exchange check button MA to release the lamp abnormality detection relay 9A coil.

摘要： PURPOSE:To reduce the friction force between a weight and a guide body by providing guide pieces each made of a short, low-friction, abrasion-resistant material at three positions in two directions in an automatic door closing device automatically closing a door via the tare weight of a weight lifted or lowered by the opening/closing shifts of the door. CONSTITUTION:When the door 4 of the landing door device of an elevator is opened by an electric driving device, a weight 11 is guided by a guide body 8 and moved upward, and the door 4 is invariably excited in the closing direction from the opened state of the door 4 by the gravitational force of the weight 11. The weight 11 is applied with acceleration and lateral force when the door 4 is opened or closed and reversed in addition to the vertical motion. Guide pieces 13 each made of a short material such as rubber are arranged at three positions in two directions of the weight 11, and each guide piece 13 is fitted with a sliding piece 13a made of a abrasion-resistant nonmetal material having a small friction coefficient. The friction force between the weight 11 and the guide body 8 is reduced, and noises caused by sliding and collision can be reduced.
