PURPOSE:To simplify structure and to facilitate verification, by a method wherein, in a control lever motion position indicating illuminating type titled panel, prismform photoconductive bodies are respectively to the backs of a control lever and a panel, light is guided to the back of the panel upon control of the lever. CONSTITUTION:The light of a lamp 23 enters the collecting surface 51 of a second photoconductive body 5 to be reflected at the inside, the light enters a feeding surface 52 and an incident surface 42 of a first photoconductive body 4 to be reflected at the inside, and passes through a groove 22 from an emitting surface 41 to irradiate the back of a panel 1. The first photoconductive body 4 is mounted to the control lever 3 which slides in a guide groove 26, and since the second prismform photoconductive body 5 extends parallel to a long groove 11 in the panel 1, when the control lever 3 slides, the back of the panel 1, simultaneously, can be irradiated with the light, and reliable position illumination can be made through simple constitution. |
