An apparatus and method for automatic translation of patent documents are provided. Translation knowledge customized for the patent domain is extracted and used. The method includes the steps of: extracting a number of technical terms from a patent document and assigning translated terms for the extracted technical terms; extracting expressions frequently used in patent documents, not in a document in a general domain, and constructing translated expressions; using the translation knowledge constructed in this way, applying a sentence pattern to extraordinarily long sentences in a patent document, dividing the sentence by recognition of parallel structure and syntax clues; and extracting translation units available for parsing and performing structure analysis.

A mobile terminal is provided which includes a terminal main body, a folder having a main LCD mounted thereon, and a hinge device for combining the folder with a main body and having a sub-LCD mounted thereon. While using the main LCD, a user can check the terminal state. In addition, the sub-LCD can be used regardless of whether the folder is opened or closed, so that display efficiency can be maximized. Moreover, since the main LCD and the sub-LCD are mounted at different positions, a thickness of the terminal can be effectively reduced.
