Abstract
According to an embodiment, an image forming apparatus includes a sheet conveyance unit that is configured to transport a print medium along a conveyance path. An antenna is configured to emit radio waves towards a predetermined portion of the conveyance path. A controller is configured to control the antenna to emit the radio waves towards the predetermined portion with a polarization direction set according to a type of the print medium being transported by the sheet conveyance unit. The print medium may have, for example, one or more wireless tags thereon or therein.
Claims19
An image forming apparatus, comprising:
- a sheet conveyance unit configured to transport a print medium along a conveyance path;
- an antenna configured to emit linearly polarized radio waves with different polarization directions towards a predetermined portion of the conveyance path;
- and
- a controller configured to select a polarization direction according to a type of the print medium being transported by the sheet conveyance unit and control the antenna to emit a linearly polarized radio wave with the selected polarization direction towards the predetermined portion.
A sheet processing method, comprising:
- identifying a type of a print medium;
- identifying wireless tag position information for the print medium according to the identified type of the print medium;
- setting parameters for writing information to one or more wireless tags on the print medium according to the identified wireless tag position information;
- starting conveyance of the print medium along a conveyance path of an image forming apparatus;
- beginning a clock at the start of the conveyance of the print medium along the conveyance path;
- writing information to a first wireless tag on the print medium using radio waves of a first polarization direction after an elapse, according to the clock, of a first time since the start of the conveyance of the print medium, the first time and the first polarization direction being parameters for writing information set according to the identified wireless tag position information;
- and
- writing information to a second wireless tag on the print medium using radio waves of a second polarization direction after an elapse, according to the clock, of a second time since the start of the conveyance of the print medium, the second time and the second polarization direction being parameters for writing information set according to the identified wireless tag position information.
