A locking positioning mechanism utilizing cam locks. After the development, the substrate is rotated so that the developer and the resist dissolved in the developer are removed. Due to this alteration, the enterprise server 544 can be connected through its port f via the communication route with the port 1 of the storage system 7, which was thus freed. A hydrogen-free amorphous film is applied to one of the component surfaces at each interface comprising an adjacent: glass component; and conductive or semiconductive component. The convex lens is configured to converge the output light from the display panel and redirect the output light approximately parallel to the central axis. The invention provides a discrimination method and a printer each of which utilizes such a carrier device capable of executing at least one process among the kind identification, the fake goods determination and the use amount calculation for the thermal transfer sheet or the thermal transfer receiving sheet based on a detection of the mark.
