PURPOSE: To improve convenience of use by providing such a constitution as capable of simultaneously displaying the content of a data code of a designated input unit on a screen on which an input unit list is displayed.
CONSTITUTION: An input data table preliminarily formed and stored is displayed on the screen of a display 31 by a host computer 38 through a keyboard 29. In the screen state where the input unit list is displayed on the screen of the display 31, a mouth 30 is operated, and a mouth cursor is moved to a desired input unit in the input unit list to designate the input unit. The switch of the mouth 30 is successively operated to partially display the data code stored in the host computer 28, for example, a carrying passage, on the screen of the display 31. Thus, the content of the data code can be read with a simple operation, and, further, the convenience of use is also significantly improved since the input unit list and the content of the data code wanted to read can be simultaneously displayed.
