Abstract: A control system comprising an electronic device equipped with a port, a hub being connectable to multiple external devices and to be connected to the port of the electronic device, and one or more external devices to be connected to the hub, the operation of the external devices connected via the hub being controlled using the electronic device, wherein the electronic device comprises a supplying section for supplying currents to the hub connected to the port and the external devices connected via the hub, and a storage section for storing the magnitude of the total current supplied from the supplying section.

Abstract: A scan ID, which is operation identification information having been used for selection of an image reading condition or the like, is used for selection of a communication destination from among a plurality of host PCs having network-connection to a scanner relay apparatus. Information such as an image reading condition associated with the scan ID is sent to a host PC defined as a communication destination, and a scan command sent back from the host PC, whose protocol is converted, is sent to a scanner apparatus. Furthermore, image data sent back from the scanner apparatus is sent to the host PC.

Abstract: An object of the invention is to provide a display device of an image forming apparatus capable of displaying information that the user wants to obtain in a visually easy-to-recognize manner. In a complex image forming apparatus provided with: one of original reading means for reading image information from an original, image receiving means for receiving image information from a terminal connected to a network and a line image receiving means for receiving image information from a telephone line; image forming means for forming an image based on the image information obtained by the means; and a display portion for displaying the condition of the apparatus, a display condition control portion is provided that changes the display condition of the display portion to a visually easy-to-recognize condition when the condition of the complex image forming apparatus is changed.

Abstract: An image forming apparatus having a plurality of discharge trays is provided, from which a user can readily obtain printed sheets he has requested. The user inputs a secret code at an operating and displaying section, which secret code the user specified at the terminal device at the time of print request (S301). When a coincidence between the inputted secret code and a secret code stored in secret code storage section is judged (S303), the target discharge tray information corresponding to the secret code is read out from a secret code storage section (memory) and displayed on the operating and displaying section (S304). Accordingly, the user can visually recognize information about a discharge tray on which the user's requested printed sheets are discharged.
