Abstract

The present invention provides a slide door device. In a slide door device, a first doorway is opened and closed by a first door, and a second doorway facing the first doorway is opened and closed by a second door. At a side portion of a space between the first doorway and the second doorway, a side light emitter is provided. At an upper portion of the space between the doorways, an upper light emitter is provided. At a lower portion of a side portion of the space between the doorways on the opposite side to the side light emitter across the space between the doorways, an imaging means for imaging the side light emitter and the upper light emitter is provided. An image processing and determination section determines, according to image data from the imaging means, whether there is an obstacle in the space.

Description

technical field [0001] The present invention relates to a sliding door device that automatically moves a door horizontally, and an elevator using the sliding door device. Background technique [0002] In the existing sliding door device, a light emitter with a long and continuous light-emitting surface is provided on one of the left and right vertical frames of the entrance, and an opposite light-emitting surface is provided on the vertical frame facing the light emitter. A camera that takes an image (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-338846 [0004] In the conventional sliding door device as described above, since the light emitter and the camera are installed on the vertical frame, when a part of passengers or luggage approaches the door, even if it is in a position where it is not actually caught by the door, sometimes will be detected as obstacles. Therefore, when this sliding door apparatus is app...
