PROBLEM TO BE SOLVED: To improve the visibility of a reflected display image by making a cover body nearly equal in size to a display opening section, fixedly maintaining a reflector of a size ranging from the lower end section of a support section to the back face on the back side of a cover section, protruding or retracting the reflector from the opening section with the opening/closing action mechanism of the cover body, and closing the opening section with the cover section at the time of retraction. SOLUTION: A cover body 15 is integrally formed with a cover section 15A having the shape and size to be fitted to a display opening section 12 and a support section 15B extending diagonally downward from its back face, and a reflector 16 is fixedly held between the lower end section of the support section 15B and the back face of the cover section 15A. An opening/closing action mechanism 18 supports the cover body 15, the forward rotating force of a drive motor rotates a screw lever 24 forward via a reduction gear group, a guide pin 20 is lowered after passing through the intermediate position of a cam groove 28, and the cover body 15 opens the display opening section 12. The reflecting surface of the reflector 16 fixed on the inner side of the cover body 15 can be set larger than the opening area of the display opening section 12, therefore visibility can be improved.
