摘要： PURPOSE:To detect accurately an anomalous of a light emitting element by making light from the light emitting element incident to another photodetector from that on a photosensitive plane by means of an optical means and driving sequentially the light emitting element so as to receive the light for processing. CONSTITUTION:The light from a light emitting diode D of a light emitting array 2 passes through a lens 2 and is projected on a photosensitive drum 1. A mirror 4 is provided so as to be saved from an optical path between a lens 3 and the drum 1, the light from the lens 3 is reflected on the mirror 4 to be passed through a Fresnel lens 5 and projected to a photodetector 6 for fault detection. When an anomalous of the light emitting element is detected, the mirror 4 is placed on the optical path and a pulse is generated from an oscillator 9, then a counter 10 counts it and inputs a count value to a storage device 13 and a register 11. The register 11 lights 12 the light emitting elements D1-Dn corresponding to the count value as a detecting point sequentially. If any light emitting element is not lighted, an output of the element 6 is (0), an output of a level discriminating circuit 8 goes to (1), and the device 13 stores the failed light emitting element corresponding to the count value of the counter 10.

摘要： PURPOSE:To detect exactly the positions of respective beams by constituting a titled device in such a way that the irradiation of the plane to be scanned by the plural beams deviates in the main scanning direction, disposing photodetection parts perpendicularly on the scanning line of the beams, putting out the beams when a photodetection part detects said beams. CONSTITUTION:Plural beams B1-B5 are deviated in the main scanning direction on the scanning lines thereof, and a photodetector E is disposed for the same perpendicularly on the scanning lines. For example, a photodiode having good responsiveness is used for the photodetector E. The plural beams overlapped in the auxiliary scanning direction are deviated respectively by the distance D at which no influences are given to the other beams. The distance D is required to be at least half the size of the beams. The beams B1-B5 are all lighted initially, then the beams are put out in order of detection with detectors. Since the putting-out of light after the detection is accomplished successively for the respective beams, the positions of the beams are exactly detected even if the beams overlap on the plane to be scanned in the auxiliary scanning direction.

摘要： PURPOSE:To detect exactly the positions of respective beams by disposing photodetection parts for detecting the positions of respective beams with deviations in the main scanning direction on the scanning lines of the beams and lighting, detecting and putting out the beams in order of the beams detected from the side where the scanning is started. CONSTITUTION:Plural photodetectors E1-E5 are disposed for plural overlapping beams B1-B5 with deviations from each other in the main scanning direction on the scanning lines of the respective beams. A detector M consisting of such photodetectors is disposed on the lateral side of a photosensitive drum 6 which is the plane to be scanned. The intervals between the respective photodetection parts in the main scanning direction are required to give no influence on the photodetection parts for the beams before the beams are lighted. When the first beams B1 is first lighted and B1 is detected in the photodetector E1, B1 is put out, then the beam B2 is lighted at the prescribed timing and when the beam B2 is detected in the photodetector E2, the beam B2 is put out. Thereafter, the similar operations are continued. As a result, the positions of the respective beams are exactly detected even if the beams overlap on the plane to be scanned.

摘要： PURPOSE:To obtain a safe copying machine wherein a laser light never reaches an original setting surface, by realizing such arrangement that the angle of incidence of the laser light to a filter is different from that of the laser light passed through the film to the filter after reflection on a photoreceptor. CONSTITUTION:Either a slit exposure optical path A and a laser light optical path B slants to the normal of the photoreceptor slightly. Then, a multi-layered interference filter 5 is provided so as to spread over both optical paths A and B set as mentioned above. When theta'>theta, spectral transmissivity shifts to a short- wavelength side and a transmission zone T2 also shifts to the short-wavelength side, so reflected laser light of 780nm from the photoreceptor is not transmitted through the filter 5.

摘要： PURPOSE:To converge plural light beams on a surface to be scanned to the points where the spacings between the convergent points of said beams are close to each other and to make a scanner difficult to receive the influence of the errors in positioning the surface to be scanned, feed errors, oscillation, etc. by providing troidal lenses for correcting the inclination of the mirror surface on a rotary polyhedral mirror to each of luminous fluxes. CONSTITUTION:The light emitted from light sources 1a-1c are converged to a horizontal line shape shown by points 4a-4c on the mirror surface of a rotary polyhedral mirror 4 by a cylindrical rod lens 3. Troidal lenses 5a-5c are disposed in such a way that the optical axes are in parallel with each other and run through the points 4a-4c. The convergence of the light from the light sources 1a-1c apart from each other by (d) on the surface to be scanned is accomplished by moving upward or downward the lenses 5a, 5c by the distance epsilon given by epsilon=(f/F)Xd where the focal length of an theta lens 6 is designated as F, and focal length of the lenses 5 as (f). The spacing between the scanning lines is made equal to the inter-dot spacing of a laser printer or the like or made proximate to each other to the extent of not so much larger than said spacing.

摘要： PURPOSE:To enable the free adjustment of the spacing between scanning lines by plural light beams from 0 up to an optional value according to the need by providing optical elements for deflecting the light beams in the direction perpendicular to a scanning direction. CONSTITUTION:Three light sources 1a-1c are juxtaposed in a perpendicular (at a right angle to the scanning direction) direction, and the three light beams formed by the same are converged as they are separately on the surface 7 to be scanned by an ftheta lens 6. Mirrors 8a-8c are inserted to reflect the beam back onto a cylinder 7 which is the surface to be scanned so that the three beams are focused apart from each other by a prescribed spacing on the cylinder 7 . At the same time, the spacing between the plural scanning lines to be swept is made equal to the inter-dot spacing of a laser printer or the like or is made approximate to each other to the extent not much larger than the same; therefore, the scanner hardly receives the influence of the errors in the positioning of the surface to be scanned or feed errors, oscillation, etc.
