Claims

[Scope of claim for utility model registration] A recording unit that records an image on a photoreceptor, a light beam emitting unit,
an optical system section in which a light beam generated by the raw potato stage is incident on a rotating polygon mirror via a modulator and a lens, and then output to the recording section via an imaging lens; a recording section and an optical system section; and a control unit that controls the optical system, the image recording device comprising: a controller interposed between the modulator and the rotating polygon mirror of the optical system unit;
An image recording device comprising a detector that detects and blocks an unmodulated light beam from a modulator.
