Abstract:
1. An image-forming system comprising: an image-forming device and a portable terminal, the image-forming device having: a printing engine part for carrying out printing, a state-detecting part for detecting a state of the image-forming device, and a panel part that includes a plurality of light-emitting elements for displaying the state of the image-forming device, the panel part adapted such that, while the state of the image-forming device is being displayed to a user by the light-emitting elements, a turned-on/turned-off pattern of the plurality of light-emitting elements is switched, and optical signals destined for the portable terminal and including information on the state of the image-forming device are transmitted; and the portable terminal having an image-capturing part, a storage part for storing an application, a display part for displaying an image and a screen, and a processing part for identifying, based on the application, the information on the state of the image-forming device included in the optical signals from image data obtained as a result of the image-capturing part capturing an image of the panel part, and for displaying, based on the application, the state of the image-forming device on the display part, the panel part uses one of the light-emitting elements from among the plurality of light-emitting elements as a reference light-emitting element for relaying to the portable terminal that the optical signals are being transmitted, the panel part switches displayed contents on a time-division basis such that display of state to the user is performed during normal display intervals and display of communication to the portable terminal, which is different from the display of state to the user, is performed during a communication display interval between the normal display intervals, the panel part switches a light-emission state of the reference light-emitting element to notify the portable terminal of switching between the normal and communication display intervals, and the processing part identifies state information contained in the optical signal from the image data obtained by image capturing performed by the image-capturing part during the communication display interval.
