IPC: G03G15/01
Filed: 1989-07-19
Abstract: PURPOSE:To prevent generation of color deviation and paper jamming and to assure the multi-layered feeding of paper by providing guiding bodies which guide the paper so that the paper is carried along direction changing parts without touching printing range of the paper in the direction changing parts of a transferring belt. CONSTITUTION:The guiding bodies 62 and 63 which guide the paper 41 to the direction changing parts 51a and 51b of the transferring belt 51 are provided. The paper 41 is carried electrostaticly attracted to the transferring belt 51 which is impressed with high voltage, and minute powder is transferred from a photosensitive body 11. When the direction changing parts 51a and 51b of the transferring belt 51 are reached by the paper 41 which is transferred, the paper 41 is made to try to proceed straightly by its own rigidness, but is carried along the direction changing parts 51a and 51b guided by the guiding bodies 62 and 63. At this time, since the guiding bodies 62 and 63 do not come into contact with the printing range of the paper 41, there is no influence on the printing range of the paper 41 which is not fixed and processed. Thus color deviation and paper jamming can be prevented from generating and the multi- layered feeding of the paper can be assured.

Abstract: PROBLEM TO BE SOLVED: To omit tilt adjustment in a position adjusting by separating a laser beam transmitting through a lens into two luminous flux and providing two or above of means which impart optical path difference to the luminous flux existing in the space as far as a photodetector. SOLUTION: A luminous flux 2j transmitted through a beam splitting surface 15a is reflected by a total reflection surface 15b, and is retransmitted through the beam splitting surface 15a, and passes through the light splitting surface 15c, and is reflected by the total reflection surface 15d, and passes again through the light splitting surface 15c to be irradiated on the photodetector 16 on a position rear from a focus. The optical path difference between a luminous flux 2a and a luminous flux 2j, first becomes a total of p+q by that it is given first by (q) between the beam splitting surface 15a and the total reflection surface 15d. The sizes of the luminous flux 2a and the luminous flux 2j on the photodetector 16 are proportional to p+q, and a gap (r) becomes r=q-p.  Thus, by selecting the values of (p) and (q), the matter independently setting of the sizes and the gap of two luminous flux on the photodetector 16 becomes possible, and the gap is reduced without changing the sizes of the luminous flux 2a and the luminous flux 2j.
