PURPOSE:To prevent a lamp holder from dropping on the ground by increasing the size of a through hole via the fitting action, and inserting an action section and an action body into the through hole when the lamp holder is fitted to a main body. CONSTITUTION:When a lamp holder 7 is to be fitted to an apparatus main body 1, the middle section of the lamp holder 7 is held, and fitting action sections 9 on both sides are pressed inward together. Projection pieces 34, 35 and 36, 37 are displaced inward, and the size of a through hole 10 is expanded to a diameter larger than the diameter (c) of an operation knob 6. The operation knob 6 can be inserted into the through hole 10, and the operation knob 6 is inserted into the through hole 10 downward from above together with a cord-shaped body 5. The fitted section 8 of the lamp holder 7 is coupled with the fitting section 2 of the apparatus main body 1 while the fitting action sections 9 are continuously pressed after the operation knob 6 is once inserted. The fitting action sections 9 are not pressed and are kept in the nonoperational state when the apparatus main body 1 is in use, thus the through hole 10 of the lamp holder 7 is held at the size that the operation knob 6 can not pass. |
