Abstract

PURPOSE:To easily perform indexing, by inputting items for indexing from a keyboard, retrieving the items with a storage device storing them in advance, and displaying the indexing information through readout. CONSTITUTION:A power switch is turned on, a key word for a desired item is inputted from a keyboard 2 and a callout key 21 is operated. A control circuit 6 retrieves whether or not the item of the inputted key word is stored in a storage device 7 in advance, and reads out indexing information when coincident, store it in a temporary storage circuit 8 and displays it on a display device 3. A designated page of a book is opened according to this display. If there is no coincident item in the storage device 7, for example spelling of the key work is checked if it is right. If the spelling is not clear, a search key 23 is operated, synonims are read out from the storage device 7 for sequential display, information (spelling) is selected and the key word having correct spelling is inputted again. Thus, indexing can easily be done.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an index for desired items in books such as dictionaries and encyclopedias, and more particularly to an electronic indexer that displays the location of a desired item using keystrokes.

Conventionally, in books such as dictionaries and encyclopedias, an index for a desired item is provided in a part of the book or in a separate index table, and by checking this index table, the book number and page of the desired item can be found. It was used to extract numbers, lines, etc. Therefore, you can find the desired item in the index table, find its page number,
Indexing, which involves looking at the number of lines and opening the corresponding section of a book, takes a lot of time and is very troublesome. In particular, according to English-Japanese dictionaries and the like, if a word is spelled incorrectly, it cannot be indexed and it is necessary to know the correct spelling, making indexing extremely troublesome.

The present invention is configured with books such as dictionaries and encyclopedias, and calls up the book number, number of pages and lines, etc. stored in advance in a storage device on a display device by a keyword of a desired item inputted from a keyboard. The present invention provides an electronic indexer designed for speed and convenience of indexing.

The electronic indexer of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of an electronic indexer according to the present invention. Further, FIG. 2 is a perspective view showing a state in which the electronic indexer main body as shown in FIG. 1 is combined with a book and integrated.

In FIG. 1, the main body of the electronic indexer includes a keyboard 2 for inputting keywords for indexing desired items, etc., and a display device 3 for displaying information read from a storage device built into the main body l. is provided on the surface. In addition to the keys for entering keywords, the keyboard 2 above has
A call key 21 for calling from the information storage device corresponding to the input keyword. There are function keys such as a clear key 22 for clearing keywords, etc., and a search key 23 for searching for similar words related to the keywords as needed.

Further, in FIG. 2, the above-mentioned electronic indexer is incorporated into the cover 5 of the book 4 and is integrated with the book 4.

FIG. 3 is a block diagram showing the circuit configuration of the electronic indexer described above. In the figure, reference numeral 6 denotes a control circuit that drives and controls the storage device 7, temporary storage circuit 8, display device 3, etc. in accordance with information input from the keyboard 2. The storage circuit 7 is a ROM that stores index information such as book number, number of pages, and number of lines in correspondence with index items.

Further, FIG. 4 is a flowchart showing the operating state. The indexing operation of the present invention will be explained with reference to this FIG. . Through this operation, the control circuit 6 searches whether or not the input keyword item is stored in the storage device 7 in advance, and if a match is found, the control circuit 6 searches for index information corresponding to the item stored in the storage device 7. It is read out and stored in the temporary storage circuit 8. The information stored in the temporary storage circuit 8 is displayed on the display device 3 as shown in FIG. All you have to do is follow this display to open the designated page of the book and read it.

On the other hand, if the keyword inputted from the keyboard 2 does not match any of the items stored in the storage device 7Vc, it is checked whether the spelling of the keyword is correct, for example. If it is unknown, the search key 23 is operated to read out similar words from the storage device 7 and display them sequentially on the display device 3 through the temporary storage circuit 8. Information displayed sequentially (spelling)
By selecting , re-entering the correctly spelled keyword, and operating the call key 21, the index information will be displayed on the display device 8 as described above.

As explained above, according to the electronic indexer of the present invention, when a desired item is entered from the keyboard, the index information corresponding to that item is displayed on the display device, which improves indexing speed and makes indexing convenient. become. Additionally, by adding a search function, even if you enter an incorrect item (for example, the spelling), it has the advantage of being able to be indexed, making it extremely convenient.
