摘要： PURPOSE:To obtain lower copy magnification without any great design alteration by drawing the 2nd mirror device out of the hollow in the 1st mirror device where the 2nd mirror device is normally stored, and guiding projection light directly to a drum. CONSTITUTION:The 1st mirror device 42 consisting of a fixed mirror 30 and mirrors 32 and 34 moving in parallel and lens groups 18 and 20 of high and low power are arranged replaceably to obtain desired copy magnification. The 2nd mirror device 50 consisting of mirrors 52, 54, and 56 is normally stored in the hollow of the mirror device 42 and drawn out of the hollow for low magnification; light is projected from the lens group 18 to shorten the conjugate length and guided directly to the photosensitive body 26. Thus, lower copy magnification is obtained without altering the size nor shape of a conventional device greatly.

摘要： PURPOSE:To make a mirror holder lightweight and small-sized and to reduce the production cost by constituting the mirror holder with one connecting bar and two holding plates provided in both ends of this connecting bar. CONSTITUTION:The mirror holder holds the second mirror 3 and the fourth mirror 4 orthogonally to each other and is movable on a scanning guide. The mirror holder is constituted with one connecting bar 10 and two holding plates 20 and 30 provided in both ends of this connecting bar 10. Both ends of mirrors 3 and 4 are inserted into rectangular holes 21, 22, 31, and 32 formed in the holding plates 20 and 30 to hold mirrors 3 and 4, and mirror surfaces are pressed to projections 23, 23, 24 and 24 formed in rectangular holes 21 and 22 and projections 33 and 34 formed in rectangular holes 31 and 32 to position mirrors 3 and 4.
摘要翻译：目的：通过在连接杆的两端设置一个连接杆和两个固定板构成镜架，使重量轻，尺寸更小的镜架保持较小的生产成本。构成：反射镜支架将第二反射镜3和第四反射镜4彼此正交地夹持并且可在扫描引导件上移动。镜支架由一个连接杆10和设置在该连接杆10的两端的两个保持板20和30构成。反射镜3和4的两端插入形成在该连接杆10中的矩形孔21,22,31和32中。保持板20和30以保持反射镜3和4，并且镜表面被压到形成在矩形孔21和22中的突起23,23,24和24以及形成在矩形孔31和32中的突起33和34以定位反射镜3和 4。

摘要： PURPOSE:To obtain a desired spectral reflection factor characteristic, by providing thin films consisting of high refractive index dielectric and low refractive index dielectric, by odd layers of 3 or more reciprocally on the metallic reflecting film, and forming a reflector. CONSTITUTION:A reflecting film 7 is formed on the supporting body 6 by means of vacuum deposition, etc. A thin film 8 of TiO2 having high refractive index onto this reflecting film 7, also a thin film 9 of MgF2 having low refractive index onto this thin film 8, and furthermore a thin film 10 of TiO2 onto this thin film 9, are formed respectively by means of vacuum deposition, etc. Each optical film thickness nn of said thin films 8, 9, 10 is one-third of the wavelength lambda of 550nm, and one- fourth of the wavelength lambda of 730nm or so. The spectral reflection factor characteristic in case when said thin films have been laminated by three layers shows reflection factor of 94-95% in case of 550nm, and shows 80% and 10% in case of 700 and 800nm, respectively. Accordingly, by means of said constitution, a desired spectral reflection characteristic can be obtained by increasing the reflection factor in the desired wave length area and lowering the reflection factor in the unnecessary wavelength area.

摘要： PURPOSE:To make it easy to adjust to align the generating line of a photosensitive drum and the center line of an optical image by coactively turning two mirrors. CONSTITUTION:The other ends of a supporting frame 806 supporting mirror carriage 701 and 801, which are rotatable about horizontal axes 704 and 811, are connected through respective slots 705 and 812 to an adjusting plate 11. By this adjusting plate 11, the carriage 701 and the frame 812 are coactively turned so as to adjust the center line of the optical image to a photosensitive drum 1 by the mirrors 7 and 8 which are operative to reflect the image having passed through a lens 6. If the carriage 812 is rotationally adjusted with respect to the frame 812, the center line of the image is adjusted. As a result, the generating line of the photosensitive drum can be aligned with the center line of the image through such easy adjustment.
