Claims

[Claims for Utility Model Registration] (1) A light guide plate made of a transparent member that is illuminated by a lighting element is disposed on the back side of the LCD, and the light emitted from the light guide plate illuminates the LCD and controls the operation knob. A protrusion whose end face is arranged opposite to the back surface of the light guide plate is integrally formed with the light guide plate, and the operation knob is illuminated with light emitted from the end face of the protrusion. A lighting device with a control knob. (2) At least the front surface of the operating knob made of a light-transmitting member is covered with a light-shielding member, and an operation display symbol is cut out in the light-shielding member, so that the operation display is displayed using light emitted from the end face of the protrusion. 2. The operating knob illumination device according to claim 1, wherein the symbol is illuminated from the back side. (3) A recess is formed on the back surface of the operating knob of the press operation switch, and the tip of the protrusion is inserted into the recess so that it can be moved freely in the direction of the press operation. An illumination device for an operating knob according to claim 2. (4) The illumination device for an operating knob according to claim 1, wherein the light emitted from the end face of the protruding portion is configured to irradiate the operating knob from the peripheral edge thereof toward the front of the operating knob.
