The image forming device according to the embodiment includes: a placement unit, a wireless tag communication unit, and a conductor. A sheet provided with a wireless tag can be placed in the placement unit. The wireless tag communication unit can write information to the wireless tag provided on the sheet. The conductor is provided in the placement unit and hinders communication between the wireless tag communication unit and the wireless tag. ## Claims ### Claim 1 An image forming device, comprising: a placement component configured to accommodate a sheet provided with a wireless tag; a wireless tag communication writer configured to write information to the wireless tag provided on the sheet conveyed from the placement component; and a conductor provided in the placement component, the conductor configured to hinder communication between the wireless tag communication writer and the wireless tag provided with the sheet placed on the conductor, wherein the placement component comprises a recess configured to receive the conductor, and wherein the conductor is provided such that a sheet placement surface is flat. ### Claim 2 (depends on 1) The image forming device according to claim 1, further comprising: a printer unit that forms an image on the sheet, wherein the sheet on which the image is formed is a sheet stored in the placement component. ### Claim 3 (depends on 1) The image forming device according to claim 1, further comprising: a discharge unit to which the sheet on which an image is formed is discharged. ### Claim 4 (depends on 1) The image forming device according to claim 1, wherein the conductor is provided at a position at which the conductor overlaps with the wireless tag. ### Claim 5 (depends on 1) The image forming device according to claim 1, wherein the conductor is provided in a placement component in which the wireless tag communication writer has not yet written information to the wireless tag of the sheet accommodated in the placement component, but the conductor is not provided in a placement component in which the wireless tag communication writer has already written information to the wireless tag of the sheet accommodated in the placement component. ### Claim 6 (depends on 1) The image forming device according to claim 1, wherein a sheet is placed in the placement component before an image is formed thereon, or a sheet is placed in the placement component after an image is formed thereon. ### Claim 7 (depends on 1) The image forming device according to claim 1, further comprising: a conveying path through which passes the wireless tag to be written and in which the wireless tag communication writer writes information to the wireless tag by emitting a radio wave from an antenna. ### Claim 8 (depends on 1) The image forming device according to claim 1, wherein a communication range of the wireless tag communication writer extends to the placement component. ### Claim 9 (depends on 1) The image forming device according to claim 1, wherein the placement component comprises a manual feed tray. ### Claim 10 An apparatus to reduce unintended RFID writing, comprising: a placement component configured to accommodate a sheet provided with a wireless tag; a wireless tag communication writer configured to write information to the wireless tag provided on the sheet conveyed from the placement component; and a conductor provided in the placement component, the conductor configured to hinder communication between the wireless tag communication writer and the wireless tag provided with the sheet placed on the conductor, wherein the placement component comprises a recess configured to receive the conductor, and wherein the conductor is provided such that a sheet placement surface is flat. ### Claim 11 (depends on 10) The apparatus according to claim 10, further comprising: a printer unit that forms an image on the sheet, wherein the sheet on which the image is formed is a sheet stored in the placement component. ### Claim 12 (depends on 10) The apparatus according to claim 10, further comprising: a discharge unit to which the sheet on which an image is formed is discharged. ### Claim 13 (depends on 10) The apparatus according to claim 10, wherein the conductor is provided at a position at which the conductor overlaps with the wireless tag. ### Claim 14 (depends on 10) The apparatus according to claim 10, wherein the conductor is provided in a placement component in which the wireless tag communication writer has not yet written information to the wireless tag of the sheet accommodated in the placement component, but the conductor is not provided in a placement component in which the wireless tag communication writer has already written information to the wireless tag of the sheet accommodated in the placement component. ### Claim 15 (depends on 10) The apparatus according to claim 10, wherein a sheet is placed in the placement component before an image is formed thereon, or a sheet is placed in the placement component after an image is formed thereon. ### Claim 16 (depends on 10) The apparatus according to claim 10, further comprising: a conveying path through which passes the wireless tag to be written and in which the wireless tag communication writer writes information to the wireless tag by emitting a radio wave from an antenna. ### Claim 17 (depends on 10) The apparatus according to claim 10, wherein a communication range of the wireless tag communication writer extends to the placement component. ### Claim 18 (depends on 10) The apparatus according to claim 10, wherein the placement component comprises a manual feed tray. ### Claim 19 A method of mitigating unintended wireless tag writing in an image forming device, comprising: writing information to a wireless tag provided on a sheet conveyed from a placement component using a wireless tag communication writer; and hindering communication between the wireless tag communication writer and the wireless tag provided with the sheet placed on a conductor using a conductor provided in the placement component, wherein the placement component comprises a recess configured to receive the conductor, and wherein the conductor is provided such that a sheet placement surface is flat. ### Claim 20 (depends on 19) The method according to claim 19, wherein the placement component comprises a manual feed tray.
