Abstract

In a data processing device having a display and a keyboard, a cursor on the display is moved with each of input keys on the keyboard in a predetermined processing mode designated by a mode change key. There are two ways for determining the directions to which the cursor is moved. One is that the directions is determined in accordance with a positinal relationship between two keys successively operated. The other is that the directions is determined in accordance with a positional relationship between the operated key and a reference key determined in advance. Thus, each of keys for respectively inputting codes are utilized as cursor movement keys.

5. The data processing device according to claim 4 wherein said control means further controls said depressed key member so as to move the cursor in a corresponding transversal direction in case that it is determined by said second examine means that said depressed key member is located on a row on which said one of said key members is located.

6. The data processing device according to claim 5 which further comprises third examine means for examining whether said depressed key member is the same as said one of said key members, and wherein said control means further controls said depressed key member so as to move the cursor in a direction to which the cursor is moved by said one of said key members in case that it is determined by said third examine means that said depressed key member is the same as said one of said key members.

7. A data processing device comprising input means including a plurality of key members, respectively corresponding to a code to be inputted, represent means for representing character data corresponding to the inputted codes, and designate means for designating a position at which a code to be inputted on said represent means, said data processing device further comprising:

mode change means for changing an operation mode of said data processing device between a normal input mode and at least an another predetermined mode;

first examine means for examining whether said another predetermined mode is designated by said mode change means when one of said key members is operated;

control means for controlling said one of said key members, in case that said another predetermined mode is designated, so as to have a predetermined relationship with said designate means in accordance with the positional relationship between said one of said key members and a predetermined key member on said input means.

8. The data processing device according to claim 7 wherein said input means comprises a keyboard member on which each of said key members are arranged along a plurality of columns and rows, and wherein said represent means comprises a display and said designate means comprises a cursor represented on said display.

9. The data processing device according to claim 8 wherein said predetermined relationship is that said cursor is moved on said display in accordance with said positional relationship in case that one of said key members is depressed.

10. The data processing device according to claim 9 wherein said control means includes second examine means for examining whether said one of said key member is located on a row on which said predetermined key members is located, and controls said one of said key members so as to move the cursor on said display in a corresponding longitudinal direction in case that it is determined by said second examine means that said one of said key members is not located on a row on which said predetermined key member is located.

11. The data processing device according to claim 10 wherein said control means further controls said one of said key members so as to move the cursor in a corresponding transversal direction in case that it is determined by said second examine means that said one of said key members is located on a row on which said predetermined key member is located.

12. The data processing device according to claim 11 which further comprises third examine means for examining whether said one of said key members is the same as said predetermined key member, and wherein said control means further controls said one of said key members so as to move the cursor in a predetermined direction in case that it is determined by said third examine means that said one of said key members is the same as said predetermined key member.

13. A data processing device comprising input means including a plurality of key members, respectively corresponding to a code to be inputted, represent means for representing character data corresponding to the inputted codes, and designate means for designating a position at which a code to be inputted on said represent means, said data processing device further comprising:

mode change means for changing an operation mode of said data processing device between normal input mode and at least an another predetermined mode;

first examine means for examining whether said another predetermined mode is designated by said mode change means when one of said key members is operated;

second examine means for examining whether an input operation has been previously executed by means of one of said key members in case that it is determined by said first examine means that said another predetermined mode is designated;

first control means for controlling said designate means so as to be moved in a predetermined direction based upon a positional relationship between said one of said key members and a predetermined key member on said input means in case that it is determined by said second examine means that an input operation has not been previously executed;

memory means for storing positional data of said one of said key members; and

second control means for controlling each of said key members so as to have a predetermined relationship with said designate means in accordance with each of positional relationships between the positional data stored in said memory means and each of said key members on said input means in case that it is determined by said second examine means that an input operation has been previously executed.

14.
