PROBLEM TO BE SOLVED: To simplify the whole installation process by installing components for a measuring instrument from the same direction as other components where electric connections are included. SOLUTION: A light source A is formed from an electric bulb 1, which is provided with a recess for detention 4. A projection for retention 11 is formed on the mounting part 7 of a case 8, and a flexible circuit board 13 is installed inside the case 8. Then the electric bulb 1 is inserted to the mounting part 7 from inside the case 8 which constitutes the same direction as the internal unit installing direction, and the leads 6 of the electric bulb 1 are connected with the circuit board 13, and the light source A is installed on the part 7 through unevenness engagement of the recess 4 and projection 11. |
