摘要： A label/window position detecting device includes a conveyor, light-emitting elements, a lens, linear image sensors, image processors, and coordinate calculation units. The conveyor conveys a target object having a label/window. The light-emitting elements illuminate the target object which is being conveyed by the conveyor. The lens forms an image of the target object illuminated with the light-emitting elements. The linear image sensors photoelectrically convert image light incident through the lens into image signals. The image processors binarize the image signals obtained from the linear image sensors into monochrome binary image signals, using a predetermined threshold. The coordinate calculation units calculate a label/window position of the target object on the basis of the binary image signals from the image processors, which correspond to a label/window edge portion. A method of detecting a label/window position is also disclosed.
