IPC: G03G15/20
Filed: 1981-06-25
Abstract: PURPOSE:To prevent light from leaking toward a photoreceptor by devising the shape of a reflecting mirror and the arrangement of a light source. CONSTITUTION:Among direct light rarys shown by the solid lines, almost all of luminous flux slanting to the entry side of recording paper 2 is cut off by an elliptic reflecting mirror M and a few remaining luminous fluc illuminate the surface of the recording paper 2 nearly at right angles, but luminous flux slanting in the ejection direction of the recording paper 2 is not restrained, so even luminous flux nearlyt parallel to the surface of the recording paper 2 is present. On the other hand, luminous flux reflected by the internal surface of said mirror M is shown by dotted lines, but arranging the 2nd focus F2 of the ellipse near the trailing end of the of a fixing device on the ejection side of the recording paper 2 allow all pieces of luminous flux to slat toward the ejection side of the recording paper 2. Therefore, the major part of luminous flux generated as a result of diffused reflection on the surface of the recording paper 2 travels toward the ejection side of the recording paper 2 and less luminous flux traveling the entry side of the recording paper 2, greatly reducing the leakage of light to a photoreceptor.
