  • Such a method is known, for example, from US-A-4,306,804,
  • an adequate copying operation can be executed only after original size, copy paper size, magnification, copy quantity and the like are set before performing copying operation. Nevertheless, some setting operations are sometimes forgotten to be made, and in this case trouble takes place such as a too large or a too small copy image or a too large or too small number of copies. Particularly, when selecting automatic magnification setting function or the automatic copy paper selecting function, it takes the operator a long time to search for the operating key for selecting the above-mentioned function, or the operator sometimes cannot identify the key for selecting the above-mentioned function and operates a wrong key.
  • the above-mentioned setting operations are not required to be made wholly, and discernment between the setting operations to be made and not required to be made has to be performed, and thereby the above-mentioned trouble takes place more remarkably.
  • US-A-4,306,804 discloses a displaying method for a coying machine having an operation panel on which set image density of an original is displayed, and an automatic exposure function which automatically sets the image density data of the original based upon data detected by prescanning the original.
  • the displaying method in accordance with the present invention cleares the set data at least while the operation of setting the copy image density is carried out by automatic exposure, and the cleared set data is displayed after the operation of setting the copy image density is completed.
  • Data to be cleared in this case may be all data which can be displayed, or may be only the copy image density data which is set by carrying out automatic exposure operation.
  • the period during which display of set data is cleared is preferably a period during which operation of setting the copy image density by means of automatic exposure is completed after the automatic exposure function is selected.
  • data setting by means of key operation may be inhibited during the period when display of the above-mentioned set data is cleared.
  • Fig. 1 is a plan view showing an operation panel of a copying machine.
  • Fig. 2 is a block diagram.
