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.

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.
