<p>PURPOSE:To display in the same sense as the paper and recognize and enhance an operation by recognizing an already inputted graph data by the use of an index key and a reverse index key during an inputting a graph data. CONSTITUTION:A control means 11 reads a key input of an index key 3, a reverse index key 4 and the like and carries out an operation according to the input through a printing means 5 and the like. When a graph data is inputted and a key 4 is pushed after plural data is inputted, a pointer 1 of the graph data is returned. Thereby, an already inputted data can be recognized. When the key 3 is pushed, a display is changed from a presently displayed graph data to a nextly inputted graph data. When the key 3 is pushed with a graph key being not pushed, a paper is fed by 1/2 line and when the key 4 is pushed, the paper is returned by 1/2. Thereby, the already inputted graph data is displayed in the same sense as the paper and recognized and the operation can be enhanced.</p> |
