Glass plate processing system

A glass plate processing system comprising:

• a loading area into which a glass plate to be processed is loaded;
• a processing area located in front of the loading area and configured to perform processing on the glass plate;
• an unloading area located in front of the processing area and configured to unload the glass plate processed;
• and a conveyance mechanism configured to sequentially convey the glass plate to the areas from backward to forward in a front-rear direction,
• a first positioning means,
• wherein the glass plate processing system comprises a first positioning means, when first and second glass plates different in size and in area of an upper surface are processed, the first positioning means locating an outermost edge located outermost in a width direction of a first side edge extending in a front-rear direction on one side in the width direction of the second glass plate to be processed later on a virtual line extending in the front-rear direction and being imagined based on an outermost edge located outermost in the width direction of a first side edge extending in the front-rear direction on the one side in the width direction of the first glass plate to be processed first, and
• in the glass plate processing system, after the second glass plate is positioned by locating the outermost edge of the second glass plate on the virtual line using the first positioning means, the processing is performed on the second glass plate.
