Abstract:
1. An image forming apparatus, comprising: a document scanning section for generating image data from image information obtained by scanning a document image; a sheet feeding section located below the document scanning section for accommodating sheets of a printing medium, the sheet feeding section arranged at a predetermined distance from the document scanning section; an image forming section located between the document scanning section and the sheet feeding section for forming an image on the printing medium based on the image data fed from the document scanning section or on externally supplied image data, the image forming section having a smaller cross-sectional area when cut by a horizontal plane than either of the document scanning section and the sheet feeding section such that a sheet receiving space into which each sheet of the printing medium is ejected is left between the document scanning section and the sheet feeding section; a sheet receiving section located in the sheet receiving space for receiving the sheets of the printing medium ejected from the image forming section, the sheet receiving section having at least one sheet receiving tray; a detection sensor for detecting the sheets of the printing medium ejected to the sheet receiving section; an indicator, disposed at a side surface of the at - least one sheet receiving tray, for emitting light based on sensing results obtained by the detection sensor; a LAN board for performing a function which enables the image forming apparatus to communicate with an external device connected via a network; and a FAX board for performing a function which enables the image forming apparatus to communicate with an external device connected via a public communications line; wherein the image forming apparatus offers a choice of at least three operation modes including copier mode in which the image forming section forms an image on the printing medium based on the image data generated by the document scanning section, printer mode in which the image forming section forms an image on the printing medium based on the image data fed through the LAN board and facsimile mode in which the image forming section forms an image on the printing medium based on the image data fed through the FAX board, the indicator emits the light in different ways depending on which operation mode is currently selected, the sheet receiving section includes a plurality of sheet receiving trays, the detection sensor detects onto which sheet receiving tray any sheet of the printing medium has been ejected, the indicator is disposed at a side surface of each of the sheet receiving trays and emits the light depending on the sensing results obtained by the detection sensor in such a manner that only indicator disposed on the sheet receiving tray onto which any sheet of the printing medium has been ejected emits the light, the indicator includes a plurality of LED groups which emit the light in different colors, the indicator begins to emit the light when a specific period of time has elapsed after the printing medium has been ejected to the sheet receiving section in the copier mode and the specific period of time elapsed in copier mode is greater than a period of time elapsed in printing mode or in facsimile mode.
