<p>PURPOSE:To simplify an opening-closing operation of a panel after links are fixed and also to improve the operability of a link lock mechanism. CONSTITUTION:A first intermediate link 26 on the operating panel (rotating link 25) side is constructed of too swing links 28 and 29 being swingable in relation to a second intermediate link 27 on the apparatus main body (fixed link 24) side and of an advance-retreat link 30 regulating a single swinging operation of each of these swing links. An operating lever 31 which gives advancing and retreating motions to the advance-retreat link 30 out of these links is provided swing ably for the rotating link 25. Therefore the operating panel can be held at an arbitrary position of opening by a swinging operation of the operating lever 31, and operations of canceling fixation of the two intermediate links 26 and 27 and of fixing them by a link lock mechanism B are dispensed with when the operating panel is held at the arbitrary position of opening after the intermediate links 26 and 27 are fixed. Besides, the link lock mechanism B can be operated in sufficient separation from the main body of an apparatus.</p> |
