Abstract

An electronic dictionary for electronic translation of words or compound words in a source language to the corresponding words or compound words in a target language comprises an optical reader which optically reads the source language to be translated, and a translation unit which produces, on the basis of the data output from the optical reader, output of a target language corresponding to the source language.

Claims

1. An electronic dictionary for electronic translation of words or compound words in a source language at locations on a source medium, to corresponding words or compound words in a target language, the electronic dictionary comprising:

a housing;

an optical reader fixedly mounted in said housing so as to be fixed relative thereto, which optically reads from the source medium the source language to be translated;

a translation unit which produces, on the basis of data output from the optical reader, an output in target language, corresponding to the source language; and

means, including a printer fixedly mounted in said housing so as to be fixed relative to said housing and said optical reader, for automatically printing the target language produced by the translation unit at a fixed position on said source medium relative to the location on the source medium of the source language corresponding to the target language to be printed.

2. An electronic dictionary as in claim 1, wherein said optical reader comprises means for optically reading the source language during a single scan of the source language by the optical reader, said printing means comprises means for automatically printing the target language on the source medium during the single scan after the output in target language is produced by said translation unit.

3. An electronic dictionary as in claim 2, wherein said printing means comprises means for printing the target language on the medium immediately below the word or compound word of the source language to which the target language corresponds during the scan of the source language by said optical reader.

4. An electronic dictionary as in claim 2, wherein said printing means comprises means for printing the target language on the medium in the vicinity of the word or compound word of the source language to which the target language corresponds during the scan of the source language by said optical reader.

5. An electronic dictionary as in claim 2, wherein the source medium is a document and the source language includes a text of words or compound words printed in lines;

and said printing means comprises means for printing the target language between a line in which is provided the word or the compound word of the source language corresponding to the target language and a next line during the scan of the word or compound word by said optical reader.

6. An electronic dictionary as in claim 2, wherein the scan of the source language is performed by a scanning movement of the entire electronic dictionary and said printing means is spaced a fixed distance from said optical reader in a direction of the scan so as to compensate for the scanning movement of the electronic dictionary during a delay between the optical reading of source language by said optical reader and the printing of the target language by said printing means while the translation unit translates the output of said optical reader into the output in target language, so that the printing means prints the target language adjacent to the corresponding source language.

7. An electronic dictionary as in claim 1, wherein said optical reader faces in a given direction for reading in the source language to be translated from the source medium, and said printer is disposed adjacent said optical reader and faces in said given direction so as to facilitate printing of the target language produced by the translation unit on the source medium immediately laterally adjacent a line of the source language having the word or compound word of the source language to which the target language corresponds.

8. An electronic dictionary as in claim 1, wherein said translation unit is fixed to said optical reader and said printing means.

9. An electronic dictionary as in claim 1, wherein said optical reader and said printing means are separate from and movable with respect to said translation unit, and are electrically connected to said translation unit via a connector cord.

10. An electronic dictionary for electronic translation of words or compound words in a source language on a source medium into corresponding words or compound words in a target language, said electronic dictionary comprising:

an optical reader having means for optically reading the source language to be translated by illuminating the medium with light from a light source external to the electronic dictionary and converting light reflected by the medium into electrical signals, said optical reader having a light collector for collecting light from the external source to be directed onto the medium, said light collector including a pair of plastic plates and fluorescent dye diffused between them, and a tip to which the light is guided and at which the light is radiated outside of said light collector;

a translation unit which produces, on the basis of electrical signals, an output of target language corresponding to the source language read by the optical reader; and

a display unit having a display panel for display on said display panel of the target language produced by said translation unit, said light collector being generally planar and transparent and being disposed over said display panel.

11. An electronic dictionary as in claim 10, further comprising means for redirecting the light from said tip of said light collector toward the medium.

12. An electronic dictionary as in claim 10, wherein said optical reader faces in a given direction for reading the source language to be translated from the source medium, the electronic dictionary further comprising a printer coupled to said translation unit, disposed adjacent to and fixed relative to said optical reader and facing in said given direction so as to facilitate printing of the target language produced by the translation unit on the source medium immediately laterally adjacent a line of the source language having the word or compound word of the source language to which the target language corresponds.
