Abstract:
In an image reading apparatus, an interference suppressing unit includes a closed-loop coil that forms a suppression area disposed in a propagation area where at least either one of the electromagnetic wave for power supply and the electromagnetic wave for transmission and reception of the ID information is propagated, and suppresses a magnetic-flux change based on the magnetic-flux change in the propagation area. At least one of an image pickup device and a carrier cable is disposed in the suppression area, and consequently, interference of the electromagnetic wave for power supply or the electromagnetic wave for transmission end reception of ID information that would otherwise propagate to a reading unit with the carrier cable thereof is suppressed. Thus, even if pickup image data of the RFID card and the ID information of the electronic tag are simultaneously obtained, the obtained pickup image data can be of high quality.
