US 7,677,688 B2 · Image forming apparatus and control method thereof

Abstract

When printing an image on a printing sheet, it is judged whether or not an RFID tag has been arranged in the printing sheet. When an RFID tag has been arranged, an image indicating the presence of RFID tag is printed, or an RFID tag cutting assistant line or the like for invalidating RFID tag is printed, whereby the user can easily recognize the presence of RFID tag. Also, the user can easily cut out and invalidate the RFID tag. When the user's information has been recorded on the RFID tag, a mark indicating the writing of information into RFID tag is attached to the printing sheet, whereby the user can easily recognize the presence/absence of information recorded on RFID tag. Consequently, there can be provided a method capable of identifying and easily discarding a printing sheet with RFID tag which can leak out the user's secret, privacy information or the like, and a method for easily judging whether or not ID information has already been recorded on a printing sheet with RFID tag.

Dependent claims

An image forming apparatus for forming an output image on a recording medium according to an input image signal, comprising:

radio frequency tag detection means for detecting whether or not a radio frequency tag is arranged in a recording medium supplied for forming an output image;
and
image forming control means for controlling to generate and form an additional image indicating the presence of the radio frequency tag on the recording medium, when said radio frequency tag detection means detects that the radio frequency tag is arranged in the recording medium,
wherein the radio frequency tag includes storage means for storing information,
said radio frequency tag detection means reads position information indicating an arrangement position of the radio frequency tag from data stored in the storage means,
said image forming control means generates and forms the additional image further serving as a mark of the arrangement position of the radio frequency tag, based on the position information, and
the additional image indicating the presence of the radio frequency tag generated and formed by said image forming control means includes a cutting assistant line for cutting at least an antenna of the radio frequency tag, the cutting assistant line indicating a position where the radio frequency tag can be broken.

A method of controlling an image forming apparatus for forming an output image on a recording medium according to an input image signal, said method comprising the steps of:

detecting whether or not a radio frequency tag is arranged in a recording medium supplied for forming an output image;
and
controlling to generate and form an additional image indicating the presence of the radio frequency tag on the recording medium, when it is detected that the radio frequency tag is arranged in the recording medium in said detecting step,
wherein the radio frequency tag includes storage means for storing information,
in said detecting step, position information indicating an arrangement position of the radio frequency tag is read from data stored in the storage means,
in said controlling step, the additional image is formed to further serve as a mark of arrangement position of the radio frequency tag, based on the position information, and
the additional image indicating the presence of the radio frequency tag generated and formed in said controlling step includes a cutting assistant line for cuffing at least an antenna of the radio frequency tag, the cutting assistant line indicating a position where the radio frequency tag can be broken.
