Face light emitting illumination 24 applying light 23 to an end part 22 of a heat shrinking film 12 of a vessel body 11 is provided obliquely and upward from an arrangement position of the vessel body 11 to irradiate the light 23 of an incident angle corresponding to a refractive index of the heat shrinking film 12 so that the light 23 is fully reflected in the end part 22. Moreover, a camera 31 for obtaining the image of the bottom part of the vessel body 11 is provided obliquely and upward from the arrangement position of the vessel body 11 to obtain reflected light 32 reflected fully in the end part 22 as an image.
