When the user covers up the CD box, the holding props of the first holding piece and the second holding piece shore up the disc inside the CD box. , an inspection equipment or aligner, in the state in which a mounting portion 2 of the predetermined apparatus is contacted with that region of a major surface of a mask substrate 1a of the photo mask 1PA1 in which a light shielding pattern 1b and a mask pattern 1mr, each formed of a resist film, on the major surface of the mask substrate 1a do not exist. In a second position, the first and second band links mechanically and magnetically decouple by the magnetic pin being forced from the aperture. In the planar view, the drain electrode has a shape of a single line, the source electrode has a first portion in a line shape and a second portion in a sheath shape surrounding the drain electrode and keeping a space from the drain electrode, and the source wiring is narrower than the region of the semiconductor pattern.
