Claims

[Scope of Claim for Utility Model Registration] A recording section that records an image on a photoreceptor, and a light beam that is incident on a rotating polygon mirror from a light beam generation stage via a lens and sent to the recording section via an imaging lens. an optical system section that emits light;
In an image recording device that includes a recording section and a control section that controls an optical system section, a casing that houses the optical system section is placed above one end of the body in which the recording section is housed, and The unit is stored in the gauging with the upper blade of the recording unit adjacent to the optical system unit, and is attached to a cover integrally covering the upper part of the body, and the body and the cover unit are connected to the body so that the cover unit can be opened and closed freely. An image recording device characterized in that the image recording device is connected by a supporting member.
