PROBLEM TO BE SOLVED: To provide a top-railed sliding door device capable of preventing the coming-off or displacement of a buffer structure on the lower end side of a sliding door. SOLUTION: In this top-railed sliding door device which makes a suspended sliding door body 31 operate for opening/closing in a lateral width direction, a corner buffer member 34 composed of an elastic member is provided at the lower end-side corner portion of the sliding door body 31, and has rising piece portions 34b and 34b which are brought into contact with or brought in close vicinity to the front-side and back-side portions of the sliding door body on both the thickness-direction sides of the sliding door.

To provide an elevator system for improving the convenience of a user who cannot get on a car because of its full state and an elevator control method.SOLUTION: The elevator system includes a camera device installed in a car 2 for photographing a landing, an image analyzer 23, and an elevator control device 50. The image analyzer 23 analyzes imaging information of the landing photographed by the camera device and generates left-behind occurrence detection information when it detects that a passenger left behind is generated even though the passenger has a will to get on the car 2 and remains at the landing. The elevator control device 50 includes an automatic call generation unit 56 for automatically generating a landing call of a corresponding landing and registering the call when the left-behind occurrence detection information is generated by an image analysis processing unit 231, a response order determining unit 53 for determining a response order of the registered call, and an operation control unit 54 for operating an elevator such that cars land in the decided response order.SELECTED DRAWING: Figure 2

Device for controlling elevator

A structure for providing a controlled flash illumination of an object which is to be photographed. A source of flash illumination first illuminates the object with a preparatory flash and then, during film-exposure, with a main flash. A preparatory control structure is electrically connected with the flash source for terminating the preparatory flash when the latter produces an amount of light which has a given relation with respect to the amount of light required to be subsequently produced during the main flash in order to achieve a proper film exposure. The amount of light produced during the preparatory flash illumination is electrically stored as a first electrical quantity, and the flash source is controlled during main flash illumination to produce a second electrical quantity corresponding to the amount of light produced during the main flash illumination, with the second quantity being compared to the first quantity. As a result of this comparison the main flash control structure automatically terminates the main flash when the amount of light produced thereby has the required relationship with respect to the amount of light produced during the preparatory flash illumination.
