PURPOSE:To easily read out many pieces of information by constituting a system for reading out numerical information relating to the control of a copying machine in the order of numerical size only by a single switch even if the numerical information is stored independently of the numerical size. CONSTITUTION:On a console panel 100 in a copying machine, copying magnification is selected by a following method. In case of a fixed magnification, expansion, unmagnification, contraction 1, and contraction 2 are selected in order by a select key 69 and the selected result is displayed respectively on LEDs 81-84. In case of an optional magnification, an input key 70 is depressed at first, and then required magnification is inputted to a RAM 213 by CPUs 1, 201 as an input of 4 digits while checking a display 101 by ten keys 51-60. At that time, the magnification can be changed in each step by magnification up- and down-keys 63, 64. Thus, the four magnification values previously inputted and consisting of four digits in each magnification value are stored in the RAM 213 in the order of address size. When an optional select key 71 is depressed at the time of using the machine, the magnification values are selected in the descending order and displayed on LEDs 85-88, so that respective magnification values can be simply selected only by the single key. |
