Claim:
1. An arm construction of an intra-oral x-ray device which comprises at least two elongated support arms including a first and a last elongated support arm, at least two of the elongated support arms rotatably connected to each other by a first jointing structure disposed on facing sidewalls of said elongated support arms rotatably connected to each other by the first jointing structure, the first elongated support arm including the first jointing structure and a radiation source connected thereto by a second jointing structure located substantially at an end of the first support arm which is opposite with respect to a location of said first jointing structure, and wherein the last elongated support arm includes the first jointing structure and is connected to a support structure of the arm construction by a connection located substantially at an end of the last support arm which is opposite with respect to said first jointing structure, said arm construction being configured such that said at least two elongated support arms are turnable with respect to a physical or virtual joint axis defined by said first jointing structure, wherein the first jointing structure rotatably connecting two of the at least two elongated support arms is configured such that ends of said two elongated support arms opposite said first jointing structure can be positioned substantially side by side, the construction further comprising at least one of: the second jointing structure faces a sidewall of the first elongated support arm and the first and the second jointing structures on the first elongated support arm face in the same direction; the connection on the last elongated support arm and the first jointing structure of the last elongated support arm face in the same direction; and at least one further elongated support arm between said first elongated support arm and said last elongated support arm includes said first jointing structure at one of its ends and a third jointing structure at an opposite end, and wherein said first and third jointing structures face in the same direction.
