Abstract

PURPOSE:To simplify a misoperation check by storing pattern data corresponding to a plurality of patterns in a storing part and making easier an operation of reading- out the pattern data in the storing by providing a plurality of operating-parts for pattern block selection on an operating panel. CONSTITUTION:Operating parts for pattern block selection, 19a, 19b, 19c..., on which a plurality of patterns are systematically summarized, are arranged on an operating panel 5. When a selection-operating part 19c is operated, for example, literal patterns 'HIRAGANA' stored in a storing part are read out, by the number possible to indicate on an indicating part 20, and the patterns corresponding to their data are indicated on an indicating part 22d. If a desired literal pattern is not indicated, the operating part 19c may be operated repeatedly, following which the pattern data is progressively selected and the indication on the indicating part 20 is changed. When the desired literal pattern is indicated, a transparent touch panel composed on the indicating part 20 combined with the selection is touched, following which the pattern data selected is read out and the pattern is indicated on an indicating part 22b. In this way, when the selection is operated successively, a combination of a plurality of patterns can be obtained.
