When a document placed on the platen glass 20 is to be copied, the document table 22 is moved in the left-right direction in FIG. 1 with respect to the exposure lamp 26, whereby the document is exposed and scanned. When the original image is irradiated from the lens 30 (or the image writing head 34) onto the photoconductor 28 uniformly charged by the charging charger 32, the photoconductor 2
An electrostatic latent image is formed on the surface 8 according to its photoconductive property. Then, toner is attached to the electrostatic latent image by the developing device 36 to form a toner image, and the toner image is transferred by the transfer charger 40 to the recording paper 38 supplied from the registration roller 42 described later.

The paper feed unit 16 includes a paper feed tray 44, and the recording paper 38 is set in the paper feed tray 44. A paper feed roller 48 is provided above the end of the paper feed tray 44, and the recording paper 38 set in the paper feed tray 44 is carried out by the paper feed roller 48. The recording paper 38 carried out by the paper feed roller 48 is fed to the paper feed path 50 and the registration rollers 4
The image is supplied to the photoconductor 28 via the image forming apparatus 2 and the image is transferred by the transfer charger 40, and then is supplied to the fixing device 52. Then, after the image is fixed, the image is discharged onto the paper discharge tray 54.

A facsimile document intake port 58 is formed on the upper surface of the housing 12, and a facsimile document discharge port 60 is formed on the side surface of the housing 12. Then, in the paper passage path 62 from the intake port 58 to the discharge port 60,

And a CCD sensor array that receives the reflected light from the document can be used.

The platen cover 24 attached to the document table 22 holds the document placed on the platen glass 20 and blocks ambient light and guides the facsimile document 14 (FIG. 2) to the facsimile document reading section 19. A pair of left and right paper guides 76 are provided on the upper surface of the platen cover 24. The left and right paper guides 76 are supported so as to move forward and backward while maintaining an equal distance from the center of the intake port 58. Therefore, the center of the facsimile original 74 can be positioned at the center of the intake port 58 by bringing the left and right paper guides 76 into contact with both ends of the facsimile original 74.

At the time of facsimile transmission, first, the document table 2
