The input mode instruction mark M is displayed for only one second, and is displayed at the mark display position in the middle row corresponding to the written input mode name “Kana”. When the input mode switching key is operated while the kana input mode is selected, the next input mode name "ABC input" is displayed on the display 22 for about 1 second as shown in FIG. The input mode instruction mark M is displayed at the lower mark display position corresponding to the notation input mode name “ABC”. On the other hand, when the input mode switching key is operated while the alphabet input mode is selected, as shown in FIG.
The next input mode name "Romaji input" is displayed on the display 22.
Is displayed for about 1 second, and the input mode mark M is displayed at the upper mark display position corresponding to the written input mode name "Romaji". After that, the document data is displayed again on the display 22 as shown in FIG. 11, the document data input / edit processing is continued, and the document data is input in the kana input mode.

As described above, when a desired input mode is selectively selected from the Roman character input mode, the kana input mode and the alphabet input mode, the input mode name of the selected input mode is displayed on the display. Since it is displayed for a predetermined short time, the input mode name of the newly selected input mode can be easily confirmed each time, and the content of the document can be displayed over the entire display area after the predetermined short time has elapsed. Moreover, when the input mode name is displayed, the document data being displayed is temporarily saved, and the input mode name is displayed for a predetermined short time, and then the document data is displayed again. Also, the input mode can be arbitrarily changed and set. Further, when there is a key input during the display of the input mode name, the display of the input mode name is immediately stopped and the document data is displayed, so that the input operation is not hindered by the display of the input mode name.

Further, these three notation input mode names “Romaji”, “Kana” and “ABC” are shown on the surface of the curved frame portion 2b which is the outer frame of the display 22, while the selected latest input mode is shown. The small rectangular input mode instruction mark M to be instructed is displayed at the predetermined instruction mark display position on the left end portion of the display 22 in association with the corresponding notation input mode name. Can be displayed, and the latest input mode can always be confirmed by the small input mode instruction mark M.

In addition, even when the power is turned on by operating the power key, the input mode name of the input mode selected when the power is turned on is displayed on the display 22 for a predetermined short time. Even when switched to the ON state, the selected input mode can be easily confirmed.

By the way, in the above embodiment, when displaying the input mode name, the document data being displayed on the display 22 is temporarily saved in the work buffer of the RAM 40, and after the input mode name is displayed for a predetermined short time, Although the saved document data is displayed again, a pointer indicating the document data being displayed may be provided on the text memory 41, and the document data may be displayed again based on the pointer.

The input mode instruction mark M can be displayed in a blinking manner in association with the notation input mode name, and the instruction mark M can be displayed in a small arbitrary shape. It is needless to say that the present invention can be applied to various document processing apparatuses that have a small display and can selectively select a plurality of input modes to input a document.
