9. The fingerprint image cutout processing device for a tenprint card of claim 8 wherein, the cutout information input means is capable of receiving modified cutout information corresponding to additional fingerprint images of each of said ten fingers contained on said tenprint card.

10. The fingerprint image cutout processing device for a tenprint card as set forth in claim 1, wherein said cutout information input means comprises:

means for displaying tenprint card images;

means for displaying a cutout frame and a center mark to be superposed on said tenprint card images; and

means for determining positions of said cutout frame and said center mark.

11. The fingerprint image cutout processing device for a tenprint card of claim 10 wherein, the cutout information input means is capable of receiving modified cutout information corresponding to additional fingerprint images of each of said ten fingers contained on said tenprint card.

12. The fingerprint image cutout processing device for a tenprint card as set forth in claim 1, wherein said cutout information input means displays, in addition to said cutout frame, orthogonal axes to be superposed on the fingerprint image, said axes crossing each other at the center of the cutout frame, each of said axes being parallel with the respective sides of the cutout frame, to specify a core of a fingerprint image on the tenprint card and the direction of the fingerprint image in the cutout frame.

13. The fingerprint image cutout processing device for a tenprint card of claim 12 wherein, the cutout information input means is capable of receiving modified cutout information corresponding to additional fingerprint images of each of said ten fingers contained on said tenprint card.

14. The fingerprint image cutout processing device for a tenprint card as set forth in claim 1, wherein said cutout information input means comprises:
