PURPOSE:To improve a function and appearance by bearing fixed sash glass on both sides of a door and mounting a human-body detecting means on the operating line of a sliding door at a place in a transom adjacent to the upper section of the door and being not exposed to the outside of the transom. CONSTITUTION:A door 1 is suspended slidably along the guide groove 6 of a transom 3. Fixed sash glass 2 is fixed into a glass mounting groove 8 parallel with the groove 6. Sections corresponding to opening sections (door opening- closing sections) 9 at the center of the groove 8 are formed in an exposed shape under the state, in which the glass is not fixed. Detecting means such as a plurality of ultrasonic sensors 10 are installed into the groove 8 so as not to be exposed from the groove 8 of regular intervals. When even one of the sensors 10 is tuned on and a human body, etc., are detected when the door 1 is under an open state, the state of the opening of the door is maintained even when a preset closing time passes. Accordingly, the sensors can be mounted at concealed places, the human body, etc., can be detected positively, and the sensors can be set up easily. |
