Claims

[Claims for Utility Model Registration] (1) The photosensitive surface of the photosensitive drum 14, which is rotatably supported on the main body frame 12, is irradiated with light carrying printing information emitted from the printing head 18 to generate an electrostatic charge on the photosensitive surface. In an electrophotographic plotter that forms a latent image, develops this electrostatic latent image to make it visible on the photosensitive surface as a toner image, and then transfers and fixes this toner image onto paper, the main body The frame 12 supports the vicinity of both ends of a long head base 16 having the printing head 18 so as to be movable in directions toward and away from the photosensitive surface, and the vicinity of both ends of the head base 16 is supported by the body frame 12. An electrophotographic plotter characterized in that an interval adjustment mechanism is disposed to face support surfaces 12a and 12b of the head base 16 and between the support surfaces 12a and 12b and near both ends of the head base 16. (2) The photosensitive surface of the photosensitive drum 14 rotatably supported by the main body frame 12 is irradiated with light carrying printing information emitted from the print head 18 to form an electrostatic latent image on the photosensitive surface. In an electrophotographic plotter in which an electrolatent image is developed to be visualized as a toner image on the photosensitive surface, and then this toner image is transferred and fixed onto paper, the print head 18 is mounted on the main body frame 12. The vicinity of both ends of an elongated head base 16 having a head base 16 is supported so as to be movable toward and away from the photosensitive surface, and the vicinity of both ends of the head base 16 is supported on the support surfaces 12a and 12b of the main body frame 12. A space adjustment mechanism is provided between the support surfaces 12a and 12b near both ends of the head base 16 and the support surfaces 12a and 12b, which are biased toward each other and arranged to face each other.
The spacing adjustment mechanism is screwed into the vicinity of both ends of the head base 16 so as to be able to protrude and retract relative to the head base 16, so that the abutment plane 42a of the spherical body 42 at the tip is aligned with the support surface 12.
An electrophotographic plotter characterized in that the height adjusting screws 38 and 40 are closely abutted in accordance with the slopes of the arrows a and 12b.
