DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the accompanying drawings for the understanding of the present invention. The following embodiments are examples of embodying the present invention and are not intended to limit the technical scope of the present invention. 1 is a block diagram showing a control system of a word processor according to an embodiment of the present invention, FIG. 2 is a flow chart showing a processing procedure when the document information is stored in an external storage device by the word processor, and FIG. FIG. 4 is an explanatory diagram showing a storage mode of the document information stored in the external storage device and the index information corresponding thereto, and FIG. 4 is a flowchart showing a processing procedure in the document information search operation by the word processor. However, the same elements as those of the conventional word processor 1 _a shown in FIG. 5 are designated by the same reference numerals, and detailed description thereof will be omitted. The word processor 1 as an example of the document editing apparatus according to the present embodiment,
As shown in FIG. 1, the conventional word processors 1 _a and the basic structure is substantially the same, the configuration on the differences from the conventional word processors 1 _a, the document information converted from the code data representing the document information Image reducing device 4 for reducing the image data of the image data, and the image data reduced by the image reducing device 4 is compressed while being stored in the external storage device 2 by, for example, a well-known MR encoding method. An image compression / decompression device 5 for restoring the original reduced image data when reading the compressed image data from the external storage device 2 is newly provided, and the document information in the external storage device 2 by the CPU. The storage mode of the index information and the index information in the external storage device 2 is not limited to the index information and the code data of the document information, and Correspondingly, the image data reduced and compressed by the image reduction device 4 and the image compression / decompression device 5 is stored.

First, the word processor 1 having the above configuration.
The processing procedure of the operation of storing the document information created and edited in advance in the external storage device 2 will be described below with reference to the flowchart of FIG. However, in the flow charts shown in FIGS. 2 and 4, S1, S2, ... First, the code data of the document information that has been created / edited and is temporarily stored in the RAM of the editing memory is input to the image reducing device 4 (S1). Therefore, the image reducing device 4 develops the image data corresponding to the input code data into a set data of bit data as the corresponding image data (S).
2). Then, the image reducing device 4 thins out, for example, bit data at appropriate positions from the image data to reduce the image data (S3). Furthermore,
The reduced image data is subjected to data compression processing by the image compression / decompression device 5 by, for example, a well-known MR encoding method so that the storage capacity at the time of storage may be small (S4). The image data thus reduced and compressed is paired and stored in the external storage device 2 together with the corresponding code data and index information of the document information (S5), and a series of recording processing of the document information is completed. .
A storage mode of the document information and index information stored in the external storage device 2 is shown in FIG. As is clear from the figure, in the storage area of the pointer 1, the code data pointer (= 110) and the image data pointer (= 220) of the document together with the index information of the document (document information).
Is remembered. Further, the code data of the document is stored in a storage area having the pointer 110 as a head pointer, and at the same time, the image data of the document (in this case, the reduced / compressed image data of the document) has the pointer 220 as the head pointer. Is stored in the storage area. Therefore, the processing procedure for searching the document information stored in the external storage device 2 as described above will be described below with reference to FIG. When a menu of index information for searching document information is displayed on the display device 3 by a key operation from the input device, the user performs a key operation on the index information which is considered to be the target document from the displayed index information. To select (S11). Then C
The PU reads the image data corresponding to the index information from the external storage device 2 and displays it on the display device 3 based on the image data pointer of the document information written in the pointer storing the selected index information. (S12). Since the image data displayed at this time is image data that has been reduced as compared with the original code data as described above, the information amount of the image data displayed on the entire display screen of the display device 3 is the code data. This is a large amount compared to the case of 1. and the user can see a large amount of document information. Therefore, it is possible to quickly determine whether the displayed image data is a target document. Further, since the reduced image data is directly read from the index information of the document information without performing data conversion as in the conventional art,
The access time to the display device 3 is short.

When the code data of the document information is converted into image data in the image reducing device 4, it is converted according to a predetermined format. For example, the format may be the same as the original image reproduced by the code data, or may be the format in which only the character data and the symbol data of the code data are described in order from the front. At this time, as described above, when the reduced image data having the format in which the character data and the symbol data are packed in order from the front is used, the information of the document information displayed at one time on the display device 3 is used. The amount is exceptionally large. Then, when the user looks at the image data displayed on the display device 3 and judges from the contents that the document is the target document and performs a confirmation input with the confirmation key, the CPU displays the image data displayed on the display device 3. The code data of the external storage device 2 corresponding to is read out and set in the RAM (S13) to be used for the editing process of the document information. This completes the search for the document information. Although the image data reduced by the image reduction device 4 is stored in the external storage device 2 as a pair with the index information (an example of index information) in the above embodiment, the image data is used for the search processing. By storing the pointer information of the image data corresponding to the code data in the storage area of the pointer in which the code data is stored, that is, the reduced image data is paired with the document information of the code data. It is also possible to memorize. In this case, the code data corresponding to this index information is read based on the code data pointer of the selected index information, and immediately after that, the image data corresponding to this code data is read. In the apparatus of the above embodiment, the image data is directly displayed based on the image data pointer described in the pointer from the index information displayed on the display device 3 when the document information is searched. It is also possible to directly display the code data corresponding to the index information on the display device 3.
