ABSTRACT:
A miniaturized operating panel for a computer printer is provided which is simplified and miniaturized. The operating panel has a single operating button (2), a yellow display lamp (4), and a red display lamp (6). When the printer's power switch is turned on while the button (2) is kept depressed, the printer enters a function setting mode. In the function setting mode, first the yellow display lamp (4) flickers. When, during the flickering of the lamp (4), the user depresses the button (2) at least once, the first digit of a desired number is inputted in correspondence to the number of times of depression of the button. Subsequently, the red lamp (6) flickers. Similarly, the user depresses the button while the lamp (6) flickers, to input the second digit. After the second digit has been entered, both lamps (4, 6) flicker, and similarly the third digit is inputted. In this way, a three-digit setting code is inputted, so that a function item is set in the printer in correspondence to the setting code. Thereafter, the yellow lamp (4) flickers again to prompt input of another setting code.
