Presence Check and Differentiation of Direction of QR/Caution Labels

This enables the prevention of on flow of appearance defects. The caution label on the battery pack cover is pasted in a location that can be externally seen by the end customer. Detection is required to prevent indication of defects in later processes. Labels may be pasted in the wrong orientation by workers. QR reading is performed in the next process, but there is a risk that the wrong label direction will not be noticed because this is performed by workers using a hand reader.
