IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JPH03102308
Kind Code:
A
Abstract:
PURPOSE:To easily correct the deviation of irradiating position by scanning light when a main body frame is twisted by movably providing a beam transmitting member for correcting the deviation of position between a light beam deflecting means and a substance to be scanned. CONSTITUTION:The light beam transmitting member 20 whose cross section is wedge-shaped and which is a transparent body made of glass or plastic is arranged between the light beam deflecting means 3 for deflecting the luminous flux of a light source 2 and a photosensitive drum 4. Then, the member 20 is movably provided along a guiding groove 20c with a pin 20b as center. In the case that the main body frame 1, etc., is twisted with such constitution, the member 20 is adjusted to be turned by loosening a screw 20e once and it is fixed by screwing the screw 20e after confirming that the difference of the height of the scanning light L1 and L2 is eliminated. Therefore, the tilt of the scanning light is easily adjusted.
