Abstract: A folding apparatus (1) having transmitter and receiver cases (2, 10), a hinge mechanism (20) for pivotally connecting one end of the transmitter case and that of the receiver case to each other, and a hinge cover (C). The hinge mechanism is connected to corners (15a-16b) of the one end of the transmitter case and of that of the receiver case. The corners (15a-16b) are projected in the direction orthogonal to the one end of each of the transmitter and receiver cases, and the hinge mechanism is installed between the projected corners of the cases. The hinge cover has a pair of box-shaped cover members (7, 8), and a cross-section of each cover member taken in the direction orthogonal to the one end has an ellipse shape. The cover members are arranged so as to face to each other, covering and holding the hinge mechanism located between the projected corners of the transmitter and receiver cases.

Abstract: A flexible printed circuit board has first and second connection portions 18 and 19 where contacts are exposed and first and second path portions 16 and 17 where conductor patterns 11 are arranged that connect the contacts 11a and 11b of the first and second connection portions 18 and 19 together. The first and second path portions 16 and 17 are formed so as to have substantially symmetrical shapes with each other about a predetermined straight line, and the flexible printed circuit board is folded up along the straight line C1 and C2. Alternatively, a flexible printed circuit board has a conductor pattern 11 formed between first and second insulating sheets 12 and 13, and has a shielding conductor 14 fixed to the second insulating sheet 13. The flexible printed circuit board is folded up with the second insulating sheet 13 outside so that the conductor pattern 11 is enclosed inside the shielding conductor 14.
