Patent number 8625132 is assigned to Brother Kogyo Kabushiki Kaisha (
The following quote was obtained by the news editors from the background information supplied by the inventors: "Aspects of the present invention relate to an image forming device to which a replacement having a non-contact type IC tag transmitting and receiving a radio signal conveying information concerning the replacement can be detachably attachable.
"Image forming devices configured to be able to manage replacements to be attached thereto by performing wireless communication with non-contact type IC tags held on the replacements have been widely used. Regarding such an image forming device, in order to prevent erroneously performing reading/writing information with respect to a non-contact type IC tag of a replacement which is not attached to the image forming device (e.g., a non-contact type IC tag placed outside the image forming device), the image forming device is required to distinguish a replacement attached to the image forming device from a replacement which is not attached to the image forming device."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "It is possible to distinguish a replacement attached to the image forming device from a replacement not attached to the image forming device by configuring the image forming device to have attachment terminals which are electrically connected to detection contacts of the replacement in the state where the replacement is attached to the image forming device. However, even if such a configuration is adopted, a possibility remains that a contact failure occurs between the attachment terminals of the image forming device and the detection contacts of the replacement
"Aspects of the present invention are advantageous in that at least one of an image forming device and a replacement configured to reliably identify the replacement attached to the image forming device is provided.
"According to an aspect of the invention, there is provided an image forming device to which a replacement is detachably attachable. The replacement comprises: a non-contact type IC tag that stores data concerning the replacement and is able to transmit the data through a radio signal; a holding member that holds the non-contact type IC tag; and a shielding member formed to alter a state of the non-contact type IC tag between an exposed state where the non-contact type IC tag is exposed and a detection unit of the image forming device is able to detect the non-contact type IC tag, and a shielded state where the detection unit is not able to detect the non-contact type IC tag, by changing relatively a positional relationship with the holding member. The image forming device comprises: the detection unit configured to detect the non-contact types IC tag by receiving the radio signal transmitted from the non-contact type IC tag; a driving unit configured to drive at least one of the holding member and the shielding member to change the state of the non-contact type IC tag between the exposed state and the shielded state; and a controller that identifies the non-contact type IC tag detected by the detection unit as that provided in the replacement being attached to the image forming device in response to a fact that the non-contact type IC tag is intermittently detected by the detection unit while the driving unit is activated.
"It is noted that various connections are set forth between elements in the following description. It is noted that these connections in general and unless specified otherwise, may be direct or indirect and that this specification is not intended to be limiting in this respect. Aspects of the invention may be implemented in computer software as programs storable on computer-readable media including but not limited to RAMs, ROMs, flash memory, EEPROMs, CD-media, DVD-media, temporary storage, hard disk drives, floppy drives, permanent storage, and the like."
