PURPOSE:To facilitate maintenance such as cleaning of a reflecting member and to prevent deterioration of an image that is reproduced by making it possible to open and close the armor part of a device main body corresponding to the position of the reflecting member provided at the end of the device main body. CONSTITUTION:The armor part of the device main body corresponding to (opposite) the position of a mirror 3c at the end of the device main body is composed as an armor member 101 that can be opened and closed. The mirror 3c is provided with a cover member 102 for protecting it against dust. This dust protective cover may not be necessary, however it is preferable to provide it in order to improve dust protection effect. The armor member 101 of the device main body and the cover member 102 of the mirror 3c are connected via a link member 103 and can turn on fulcrums 101a and 102a as a center, respectively. Thus, when the armor member 101 is opened at the time of working on the device, the drust protective cover 102 is also opened at the same time by the action of the link member 103, so that the mirror 3c is exposed. When the armor member 101 is closed, the dust protective cover 102 is also closed at the same time. |
