Claims

[Scope of utility model registration request]

By exposing and scanning the original with an optical system, the image of the original is formed as a latent image on a photoreceptor, and the latent image is developed, transferred to transfer paper, and fixed to obtain a copy image corresponding to the image of the original. In an electrostatic recording device configured as shown in FIG. An electrostatic recording device characterized in that the electrostatic recording device is set with reference to the point of reversal at the starting end of the optical system obtained by an encoder that detects the rotation of the optical system.
