  • Patent number: 7706699
    Abstract: A toner container includes a longitudinal container body, a held portion, and an electric component. The longitudinal container body has a first end and a second end distal to the first end in a length direction of the container body. The held portion is attached to the first end of the container body and configured to be detachably attached to the toner-container holder. The held portion includes a toner outlet for discharging the toner. The electric component electrically communicates with a component in the main body to detect whether the toner container is operatively set in the toner-container holder. The electric component is attached to the held portion such that when the held portion is attached to the toner-container holder the electric component is located above the toner outlet with respect to a vertical direction.

  • Publication number: 20080130071
    Abstract: An image reading system, in which an image reading method is performed, includes a document feeder, a media determination unit, a transfer controller, an image reader, and a read controller. The document feeder feeds and transfers an original document consisting of at least one of a non-electronic medium and an electronic paper including a memory, a display unit, and a conductive member. The media determination unit determines whether the original document is the non-electronic medium or not. The transfer controller controls a transfer operation performed by the document feeder, based on results obtained by the media determination unit. The image reader optically reads either an image on the non-electronic medium or on the electronic paper. The read controller controls a reading operation performed by the image reader.
