  • Patent number: 7881654
    Abstract: A document is made which consists of a large number of recording sheets whose originality can be certified with reliability. Different specific images are respectively formed on a plurality of recording sheets of recording sheets outputted in constant order. Confirmation holes are formed on recording sheets at higher levels than the recording sheets with the specific images formed thereon, in positions in conformity with the positions of the specific images. When a document made by stacking those recording sheets is seen from the top, and the specific images are visible through the confirmation holes, the originality of the document can be certified. When the specific image is invisible through the confirmation hole, it is found that the document has been changed due to missing of part of the recording sheets, a change in order of the recording sheets, or the like, and hence the originality of the document cannot be certified.

  • Patent number: 7631090
    Abstract: When it is judged that the IP address of a PC for the administrator is not included in IP addresses received from the PC for the administrator under accessing while a PC whose access is to be authorized is registered (NO in S20), the IP address of the PC for the administrator is registered besides IP addresses received for identifying PCs (S21). Meanwhile, when it is judged that the IP address of a PC for the administrator is included in IP addresses received from the PC for the administrator under accessing while a PC whose access is to be rejected is registered (YES in S43), the IP addresses received for identifying PCs are registered after excluding the IP address of the PC for the administrator therefrom (S21). This makes it possible to avoid a situation that an access from the terminal device for the administrator to a network device becomes impossible.
