ABSTRACT:
A text processing apparatus includes: an external storage device which stores text data and is detachable for the main body of the apparatus; an internal storage device fixed in the main body of the apparatus; a display device to display the text data; an editing processor for transferring the text data stored in the external storage device to the internal storage device and for editing processing; and a comparison display device for comparing the text data which was edited processed by the editing processor with the text data which has already been stored in the external storage device, and for displaying the portion of the text data different from the text data stored in the external storage device by inverting the black-and-white indication of this data. The internal and external storage devices have the same memory structure and the same memory capacity. With this apparatus, the text data stored in the internal and external storage devices can be compared on a text unit basis or on a page unit basis without frequently accessing the external storage device. The newly added or modified text data can be easily checked.
