とを特徴とする高さ判別装置。[Claims for Utility Model Registration] A plurality of light emitting elements provided at different heights, a light receiving element provided corresponding to each of these light emitting elements to receive light from the corresponding light emitting element, and these light emitting elements. A height determination device comprising a light shielding state detection means for processing a light reception signal of a light receiving element and detecting which of the optical axes connecting the light emitting element and the corresponding light receiving element is in a light shielding state. In the apparatus, a mode switching means for switching between a teach mode and a run mode; a threshold calculating means for calculating a threshold for determining the height of an object from a detection output of the light shielding state detecting means when in the teach mode;
When in the teach mode, output setting means sets an output according to the height of the object, and when in the run mode, the detection output of the light shielding state detection means and the threshold value calculated by the threshold calculation means are used. a height determining means for determining the height of the object by comparing the height with a threshold value; and a height determining means for determining the height of the object by comparing the height with a threshold; 1. A height determination device comprising: output means for determining a height.
