PURPOSE:To simplify the structure and facilitate the manufacture by arranging the socket sections of a lamp holder so that a lamp having a large tube diameter is located on the upper side, a lamp having a small tube diameter is located on the lower side, and the circuit boards are stereoscopically crossed. CONSTITUTION:A lamp holder 19 holding circular lamps on lamp socket sections 21, 22 and lamp hold sections 23, 24 is inserted into the coupling recess 5 of an apparatus main body 1. Elastic hook pieces 53 of the holder 19 are coupled and held in the recess 5 of the main body 1. The connection section of the holder 19 is inserted and connected to a connector via the guide of guide pieces 62, and the socket sections 21, 22 are connected to the lighting circuit of a circuit board. The lamp having a large tube diameter is arranged on the upper side of the holder 19, the lamp having a small tube diameter is arranged on the lower side, and the conducting patterns of the socket sections 21, 22 are crossed at the socket sections 21, 22. The structure is simplified, and the diversification of the apparatus design is facilitated. |
