Abstract: A plurality of icon data and keywords respectively corresponding to the icon data are stored in an icon data storage section. Matching between the data input by the data input section and a keyword stored in the icon data storage section is detected. Icon data stored in the icon data storage section in correspondence with a keyword which is detected to match the data input by the data input section is added to the input data, and the obtained data is displayed.

Abstract: A data storage device comprises a controller and a semiconductor chip which includes a nonvolatile semiconductor memory having plural storage areas into each of which data is stored, a store instruction signal input terminal to which a store instruction signal is inputted, a storage controller for storing data into the semiconductor memory when receiving a store instruction signal through the store instruction signal input terminal, a read instruction signal input terminal to which a read instruction signal is inputted, and a read controller for sequentially specifying one of the storage areas in the semiconductor memory each time it receives a read instruction signal through the read instruction signal input terminal and then reading the data stored in the specified storage area.

Abstract: In an MR coding operation for processing a facsimile image, relationships among changing pixels "a1", "a2", "b1" and "b2" are judged, and then after performing process operations of a horizontal mode and a vertical mode, confirmation is made whether or not the changing pixels "b1" and "b2" must be newly checked. When the changing pixels "b1" and "b2" are not required for a new detection, the changing pixels "b1" and "b2" which have been obtained during the preceding coding operation are employed in the subsequent coding operation. As a consequence, the operation to obtain the changing points in the pixels can be omitted and thus a highspeed coding process may be achieved.

Abstract: A hand-held image reading apparatus reads image data corresponding to image information from a surface and prints the image data on a printing medium. The apparatus reads the image data by moving over the surface. Further, the apparatus stores the read image data in an internal memory, extracts the image data existing in the center of the image data stored in the memory and prints only the extracted image data on the printing medium.
