PURPOSE: To easily confirm the nonmatching place and the nonmatching content of a new and an old images which should be compared, to more easily understand them and to prevent a test plate device from executing an erroneous deciding action by using a color mark already written on the image by providing an electronic image read means reading the respective images with a color filter. CONSTITUTION: CCD cameras 4 and 5 are respectively connected to two platters 2 and 3 as the electronic image read means through CCD driving controllers 6 and 7. Then, a color filter part is properly provided with the single color filter such as a blue, a red, a green or a yellow or properly provided with the plural color filters so that it can be attached and detached or switched every color with respect to an image read optical system. Since the read means 4 and 5 reading the image are provided with the color filters in such a way, the erroneous read action thereof is evaded by regarding the colored check mark and the like as nonmatching. |
