In this case, a light condensing light source for irradiating the linear light in the form of linear light is used, and a light source horizontal moving part for horizontally moving the light condensing light source to irradiate all portions of the transparent plate is provided. In this case, since strong light is produced by the condensing light source, the reaction time is shortened. Finally, it is possible to use a scattering light source that can simultaneously irradiate the front surface of the transparent plate. In this case, since the light source is not moved, the structure of the device is simplified, but the intensity of the irradiated light is weakened, so that the time for irradiating light is long.
