PROBLEM TO BE SOLVED: To provide an image information equipment capable of avoiding such a situation that a document disappears by changing set contents such as time change. SOLUTION: The storing times of all stored documents are acquired (503), whether there is a file to be soon erased accompanying the present time change is checked (504), whether files that have been stored for more than one hour before the present time change and have been automatically erased within one hour after the present time change exist, is further checked (505 and 506), and when corresponding files exist, a flag sugu (soon) and a flag mamonaku (before long) are respectively set in the corresponding files (509 and 510). When the flags are erected at the point of time when the retrieval of all the documents is finished (YES in 511 and YES in 512), an image for alarm and password entries is displayed (513), a manager password is compared with an inputted password (514), and when the manager password coincides with the inputted password (YES in 514), the present time and set time to be elapsed up to erasure are changed (515).
