Abstract

PURPOSE:To enough execute a key input even in the case of an electronic dictionary in a picture input system by providing a transparent piezoelectric switch on the surface of a display on an armoring case. CONSTITUTION:On the armoring case 6, a picture reading window 7 to execute the picture input and an encoder roll 8 to transmit the traveling amount of an electronic pocket dictionary to the surface of paper is arranged on the same surface. On the other hand, on the surface of a panel 9 on the upper surface of the armoring case 6, the film of the piezoelectric switch exists and under the film, the display exists. As the display, for example, liquid crystal is used. Assuming that the display 10 exists in a part of the panel 9 and the part in the range of the display 10 is depressed, it can be set to start reading a character picture. Thus, since the transparent piezoelectric switch is provided on the surface of the display, the key input to make one character correspondent to one general key can be executed in spite of the electronic dictionary in the picture input system.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pocket electronic dictionary.

(Prior art) Electronic dictionaries that obtain the translation of words and sentences in a string of characters on a manuscript paper have two methods of inputting characters: manual input using keys, and optical methods that read and recognize characters as images. There is a way to do it.

The latter method does not require any troublesome key operations, so anyone can easily input characters accurately.

Additionally, since there is no need for keys for character input, the mounting area of the keys can be significantly reduced, making it possible to widen the display, expand functionality, or integrate everything. .

[Problem to be solved by the invention]

However, image input type electronic dictionaries target characters written on paper or printed characters. Therefore, if you want to check the spelling of a word you have memorized, you have no choice but to write it roughly once on a piece of paper and input it to have it recognized. This is why some electronic dictionaries that use image input also allow key input.

However, integrated devices such as pocket electronic dictionaries have an extremely small area available for mounting keys, etc. For example, it is not possible to use keys that correspond to individual letters of the alphabet.

Therefore, the keys used for inputting images and searching for candidate characters for recognition are also used as key input keys for key input, but since the operation is complicated, this is only an emergency measure. There is only one way.

On the other hand, there are restrictions not only on the keys but also on the size of the display, so pocket electronic dictionaries can only be used with a few lines. In particular, when displaying a translation, the meaning may not be fully understood because it is cut off in the middle or there are only a few characters that can be used.

The present invention solves the above problems, and its purpose is to:
To obtain a pocket electronic dictionary in which keys and a display can perform sufficient functions within the limited area of the pocket electronic dictionary, and key input can be performed satisfactorily even if the electronic dictionary uses an image input method. There is a particular thing.

[Means for solving problems]

(1) The pocket electronic dictionary of the present invention includes an image input means for reading character strings etc. on the surface of a manuscript as image information, and a character recognition means for recognizing the image information read by the image input means as a character string. , a translation means having a dictionary necessary for translating the characters recognized by the character recognition means and the translation, and a display means for displaying the translation results of the one-wing translation means and internal information of the main body of the pocket electronic dictionary of the present invention. and,
The image input means, the character recognition means, the translation means, and the display means are provided with key input means for inputting commands and character strings, and each of the above means is integrated, and a display on the outer case is provided. A transparent piezoelectric switch is provided on the surface of the device.

(2) The pocket electronic dictionary is characterized by comprising online character recognition means that recognizes input from the piezoelectric switch as a character string.

[Effect]

By installing a transparent piezoelectric switch on the surface of the display,
Display and key input can be performed in the same place. If the display is tailored to the function of the key, only the necessary functions will be displayed, which will require much less space than providing several dedicated keys.

Furthermore, if the input on the piezoelectric switch is performed as online input character recognition, the area for input will be further reduced.
Improves operability.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the pocket electronic dictionary of this invention will be explained in detail based on an Example.

FIG. 1 is a diagram showing the basic configuration of a pocket electronic dictionary of the present invention.

A character string printed or written on the manuscript paper is read as an optical image and converted into an electrical signal. It is recognized and encoded as one character string.

The encoded character string is translated by the translation means 3 with reference to translation dictionary data to obtain a translation corresponding to the character string, and the result is displayed on the display means 4.

On the other hand, input from the piezoelectric switch gives commands to each of the above means. In addition, when performing character recognition using online input,
The input signal from the piezoelectric switch is recognized as a character by the character recognition means 2. (Key input means 5) FIG. 2 is a diagram showing an example of the external appearance of the pocket electronic dictionary of the present invention.

On the exterior case 6, an image reading window 7 for inputting images and an encoder roller 8 for transmitting the movement of the pocket electronic dictionary relative to the paper surface are arranged on the same surface.

On the other hand, a panel 9 is provided on the upper surface of the exterior case 6. On the surface of the panel 9, there is a film of a piezoelectric switch, and below it there is a display, for example, a liquid crystal is used as the 0 display. Assume that there is a display 10 in a part of the panel 9. For example, it can be set so that when the area of the display 10 is pressed, reading of the character image starts.

FIG. 3 is a block diagram showing an example of a circuit configuration.

The character string on the original 11 is illuminated by the light source 12 and the lens 1
3 connects the image to the sensor 14, the sensor 14 converts the connected image into an electrical signal, and the image reading unit 15 connects the image to the R
Data is stored in AM20. The timing of writing data to the RAM 20 is determined by a roller 16 that contacts the document 11 and transmits movement, a belt 17 that transmits the rotation of the roller 16, a slit plate 18 that rotates with the rotation of the roller 16, and a movable type that uses the rotation of the slit plate 18. It is determined based on the signal from the photo interlayer 19 that outputs the .

Next, the data in the RAM 20 is converted into a character string by the character recognition unit 2.
The data required for recognition, matching, etc. in step 1 is as follows:
All of the information is stored in the recognition data ROM 22, and recognition is performed based on this data.

The recognized character string is passed as a character code to the translation unit 23, where appropriate translation is performed based on the data in the dictionary data ROM 24, and the result is displayed on the display unit 25, for example, on the liquid crystal display 26. Ru.

The display includes information such as the image reading status and the recognition results themselves.
．． It also conveys various information.

On the other hand, there is actually a piezoelectric switch plate 28 mounted just above the liquid crystal display 26. This piezoelectric switch board is
Generally, a resistor whose resistance value changes when the surface is pressed is often used.The resistance value changes depending on the position where the object is pressed, so by applying a constant voltage, it is possible to determine the position on the surface where the object is being pressed from the change in voltage. The voltage change of the piezoelectric switch plate 28 is detected by the input detection section 27. An AD converter or the like is used to change the voltage. Piezoelectric switch board 2 for simple key input
8, commands corresponding to the input are sent to the image reading unit 15, character recognition unit 21, and translation unit 23.

On the other hand, when handwritten characters are input online, the data of the trajectory is stored in the RAM 29. RAM2
The data No. 9 is recognized as a character string by the online character recognition unit 30 based on information such as strokes contained in the online recognition data ROM 31, encoded, and passed to the translation unit 23.

RAM and ROM memory can generally be stored in an integrated case, but if necessary,
Information may also be exchanged with external devices (floppy disks, hard disk devices, etc.).

FIG. 4 is a diagram showing how to use the pocket electronic meter 1 of the present invention.

FIG. 4(a) shows how to use the image input method. now,
When using the pocket electronic dictionary with your right hand, your thumb will be on the surface of the panel 9 when you grip it.

If it is set so that image input starts when pressure is applied to the area touched by the thumb on the panel 9, image input can be performed without providing a dedicated key.

If you keep your fingers in a wide range, you can type instantly as if you were just holding a pocket electronic dictionary.

FIG. 4(b) shows a case where the system is used for handwritten character input in online input.

First, place the pocket electronic dictionary on a stable place such as a desk, and trace the surface of the panel 9 with, for example, a pen 32 (it does not emit ink, just trace).For example, change the pressure in a certain range on the right end of the panel 9. Suppose you decide to input it online and use other parts for display. If the user is left-handed, the user can move the range for online input to the left end and use the rest of the screen for display.

Alternatively, the entire panel 9 may be configured to allow online input, and the input results may be displayed near the area traced on the panel.

FIG. 5 is a diagram showing a display example.

Figure 5 (a) is an example of the display when using the image input method as in Figure 4 (a).
The area 33 indicates the area where the thumb touches ``N NOW'', and the user is instructed to press this when inputting. It may also be a character indicating an instruction.

FIG. 5(b) is an example in which an image is input, recognition is performed, and the translation is displayed. Currently, the "apple" of the word translation is displayed, but if you want to see the front of the built-in dictionary, press near arrow 34, and if you want to look back, press near arrow 35.In addition, When you want to see the original word, just display it on the panel according to the machine you are using and instruct the user to press it.

FIG. 5(e) is a diagram showing an example of the display when performing online input as shown in FIG. 4(b).

Online input is performed in the area surrounded by range 39, and the input results are displayed at the left end at any time. Currently, when you have entered up to "7" of ° "Honyaku", there is a blink 38 at ° "7". To move the blink 38 to the left, press the arrow 36, to move it to the right, press the arrow 37, and then press the arrow 37 again. Enter information and make corrections in step 39.

As mentioned above, if the user is left-handed, the range 39 and other displays (blink 38, arrows 36, 37, etc.) may be swapped left and right.

In this way, by providing a transparent piezoelectric switch directly above the display, keys, online input, and display can be freely set. Moreover, it can be easily adapted to whether the user is right-handed or left-handed.

For general key input other than online handwritten character input, the display area is relatively large, so for example, all 26 letters of the alphabet can be input side by side.

〔Effect of the invention〕

As mentioned above, because a transparent piezoelectric switch is installed on the surface of the display, even though it is an image input type electronic dictionary,
It is possible to input a key corresponding to one character with one general key.

Furthermore, if online handwritten character input is also possible, character input will become even easier.

The display and the transparent piezoelectric switch are arranged on the same plane, making the display more efficient and effective, and key functions only need to be instructed when they are to be used. It becomes a function. Pocket electronic dictionaries in particular meet the requirements of making effective use of a small area, having multiple functions, and not becoming complicated.

Furthermore, since no dedicated switch is provided, the outer case has fewer irregularities, making it easier to grip.
