PROBLEM TO BE SOLVED: To provide an irradiation mechanism for display capable of composing a multiscreen display of a multi-irradiation mechanism type at a low price with a simple and small structure. SOLUTION: The terminal device is provided with a back light mechanism for illuminating display screens 15a, 15b uniformly inside the main body 11 of the terminal device having two plate surfaces as the display screens 15a, 15b combined rotatably and foldable by a rotary shaft part 11a as usual. A cylindrical shape storing part in the rotary shaft part 11a is provided with a cold cathode tube 12 along the axial direction of the rotary shaft part 11a which is the principal part of the back light mechanism, a transparent protective cover 13 consisting of a transparent heat-resisting material for covering the outer peripheral surface of the cold cathode tube 12 to protect it, and the cylindrical part of a light guide lens part 14 covering the outer peripheral surface of the transparent protective cover 13 to guide uniform dispersion of light irradiated from the cold cathode tube 12 on the display screens 15a, 15b. |
