PROBLEM TO BE SOLVED: To improve a structure related to opening and closing of a lid in an operation panel provided with a turnable lid with one end held around the turning center so that it opens and closes on an operation panel body. SOLUTION: When a lid 102 is turned to open by a specified angle from its close state, a tongue 115 of the lid 102 mounts on a protrusion 16a of a click 116 of a cover 101 of an operation panel body and fits to the click 116 elastically, and the lid 102 is held. When the lid 102 is further turned in opening direction, a wall 117 of the lid strikes against a stopper 118 of the cover 101 and the lid 102 is thereby held. When the lid 102 is further opened, a rotation central shaft 111 of the cover 101 falls off from an opening 119 of a fitting part 114 of a lid and the lid 102 comes off from the cover 101.
