  • the present invention relates to an operation panel and a displaying method of a copying machine, and more specifically, to an operation panel which facilitates recognition of various operating keys on the operation panel and displays for displaying various data and a displaying method which enables an adequate recognition of data to be set and entered by the operator or enables display of automatic exposure operation state without increasing the kind of displays.
  • an adequate copying operation can be made only after original size, copy paper size, magnification, copy quantity and the like are set before performing copying operation. Nevertheless, some setting operation is sometimes forgotten to be made, and in this case a trouble takes place such as excessively large or small copy image or excessively large or small quantity 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.
  • An object of the present invention is to facilitate recognition of various displays on an operation panel of a multi-functional copying machine.

  • Still another object of the present invention is to prevent an original cover from being opened in the middle of operation of the automatic exposure function of a copying machine provided with the automatic exposure function.
  • Still another object of the present invention is to display the state wherein the automatic exposure function is carried out without complicating display of the operation panel.
  • a print key is mounted on the right end part of the operation panel of a copying machine, and also displays of various set data are mounted collectively on the center part of the copying machine, a set magnification display part is formed at one end part of the displays in the right-left direction thereof and a set density display part at the other end part thereof respectively, a magnification setting key is mounted close to the set magnification display part and a density setting key is mounted close to the set density display part respectively, an original size display symbol is formed close to one side edge of the displays in the up-down direction thereof, and a copy paper size display symbol is formed close to the other side edge thereof respectively, and further various function selecting keys are mounted collectively somewhat apart from the displays.
  • These function selecting keys may include an automatic magnification set state selecting key, an automatic copy paper size set state selecting key and an automatic copy image density set state selecting key, and respective manual operating keys which set and enter the above-mentioned data by manual operation may be colored the same as the above-mentioned respective keys, and the keys in a corresponding relation may be mounted close to each other.
  • a displaying method in accordance with the present invention clears display on the operation panel of data to be set and entered by the operator before starting copying operation.
  • Clearing of data display in this case may be made only by operating a specific key, may be made by operating a nonspecific key or may be made automatically every time copying operation is completed.
  • data to be cleared may be all of data which can be displayed, or may be only data that setting operation is to be made corresponding to a selected function, for example, the automatic magnification setting function, the automatic copy paper selecting function or the like. Specifically, it may be the original size display data, the copy paper size display data, the magnification display data and the copy quantity display data.
  • the displaying method in accordance with the present invention clears the set data at least during operation of setting the copy image density is carried out by automatic exposure, and the 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 of 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. 6 is a major part schematic diagram clearly showing an internal mechanism of an copying machine which is of a type wherein an optical system moves and employs a photoreceptor drum as a photoreceptor.
  • Numeral 1 is an original placing table located on the top surface of a copying machine main body (not illustrated), and at a predetermined position thereunder, an optical part 2 constituted with an exposure lamp 21, reflecting mirrors 22, 23 and 24, a lens 25 and a reflecting mirror 26 is provided and an original D can be scanned to be exposed in sequence by moving the exposure lamp 21 and the reflecting mirrors 22, 23 24 in the direction as shown by an arrow A.
