とを特徴とする画像記録装置。 An optical system that includes two units that are connected to each other so as to be openable and closable and that house a mechanism section for forming an image and a control section that controls the units, and a light source that is housed in one of these two units and that emits a light beam. In an image recording device equipped with a scanning device,
The optical scanning device is provided with a shielding means for shielding the light beam emitted from the light source when the two units are opened, and the other of the two units is provided with a shielding means for shielding the light beam when the two units are closed. What is claimed is: 1. An image recording apparatus comprising: a shielding release means for releasing the shielding means; and a flexible sealing member for sealing a portion of the shielding means operated by the release means.
