摘要： PURPOSE:To obtain a printer which employs a normal development system that provides a white background to a print inhibition area by providing a light emitting element which irradiate a printing form with light except in its print area. CONSTITUTION:A laser is turned on while the scanning position of light is on the left-hand side of a detector 3' every time one photoscan is made (from left to right); when the photodetector 3' is passed through, the time is recognized and sent to a computer 12 and the laser light is held on state as it is. The position interval between the detector 3' and left end 13 of the print area is known previously, so the computer 12 sends a print signal laser modulated signal to a laser light source 15 at the position. The laser light is turned on again at the right end 14 of the print area to complete one scan. This scan is made repeatedly to make a photoscan on one printing form, providing a white background to the print inhibition area.

摘要： PURPOSE:To obtain a titled mirror having high reflectivity and a less change in the intensity of scanning light by machining Al or an Al alloy to a specular surface then anodizing the surface to form a protective film. CONSTITUTION:A rotary polyhedral mirror member 1 is Al or an Al alloy and a specular surface 2 is formed thereon by machining. A thin transparent film 3 for protecting the surface 2 is formed by an anodization method. When the reflecting mirror is tilted to perform optical scanning, the incident angle of light changes with the rotating angle of the mirror and the optical film thickness changes with said change, then the intensity of the scanning light changes in accordance with the rotation of the reflecting mirror. The film thickness (d) when the incident angle in the optical scanning range changes from theta1 to theta2 changes from dtheta1=mlambda/2n1costheta1 to dtheta2=mlambda/2n1costheta2. lambda: wavelength, (m): positive integer except 0, n1: the refractive index of the anodized film, dtheta1
摘要翻译：目的：为了通过将Al或Al合金加工成镜面来获得具有高反射率和较小扫描强度变化的标称镜，然后阳极氧化该表面以形成保护膜。构成：旋转多面体镜构件1为Al或Al合金，通过机械加工形成镜面2。通过阳极氧化法形成用于保护表面2的薄的透明膜3。当反射镜倾斜以执行光学扫描时，光的入射角随着反射镜的旋转角度而变化，并且光学膜厚度随着所述变化而变化，则扫描光的强度根据反射的旋转而改变镜子。当光扫描范围内的入射角度从θ1变化到θ2时的膜厚度（d）从dθ= 1 /λ1/ 2n1costheta1变化到dθ= 2 /λ1/ 2n1。 λ：波长，（m）：除0之外的正整数，n1：阳极氧化膜的折射率，dθ= 1。反射光强度的变化最小的膜厚是在扫描角的中心处光强度最大的膜厚特性曲线7。在这种情况下，厚度从E变为F，但波动最小。因此，光学膜厚度设定在dθ= 0 /λ/ 2costheta0。

摘要： PURPOSE:To maintain the high reflection property that a reflecting mirror has and further obtain flat, less-variation characteristics of the intensity of deflected scanning light by utilizing the interference characteristics of a thin film to an angle of incidence and polarizing reflection characteristics on a metallic surface in combination. CONSTITUTION:A polygon mirror consists of a rotary polygon mirror body 3, reflecting surfaces 4, and a specular surface protection film 5 and rotates on its axis 6 of rotation to deflect and scan laser light incident to the reflecting surfaces 4 through the protection film 5. When light is defelected and scanned by the reflecting mirror coated with the transparent protection film as mentioned above, variation in angle of incidence to the tansparent thin film is caused in addition to variation in reflection characteristics on the metallic surface, so the interference condition of the thin film varies to cause variation in reflection factor. For this purpose, S deflection scanning characteristics which increase the reflection factor with the angle of incidence are applied in combination to allow the reflection characteristics to cancel each other, and consequently there is no influence of variation in angle of incidence to make a light scan with flat characteristics of reflected light intensity. Then when the light scan is made with a high reflection factor, S polarization is employed for the scanning and the optical film thickness of the protection film at the angle of incidence when the deflecting scan is made is set almost to mlambda/2.
摘要翻译：目的：为了保持反射镜具有的高反射特性，并且通过利用薄膜的干涉特性与金属的入射角和偏振反射特性，进一步获得偏转的扫描光的强度的平坦的，较小的变化特性表面组合。构成：多面镜包括旋转多面体镜体3，反射面4和镜面保护膜5，并在其旋转轴线6上旋转，以通过保护膜5偏转和扫描入射到反射面4的激光。当通过如上所述涂覆有透明保护膜的反射镜反光并扫描光时，除了金属表面上的反射特性的变化之外，还引起与透明薄膜的入射角的变化，所以干扰条件薄膜变化，导致反射系数的变化。为此，组合使用增加入射角的反射系数的S偏转扫描特性，以使反射特性彼此抵消，因此不会影响入射角的变化，从而进行光扫描平坦的反射光强度特性。然后当以高反射率进行光扫描时，采用S偏振作为扫描，并且当进行偏转扫描时，入射角处的保护膜的光学膜厚度被设定为几乎为λλ/ 2。

摘要： PURPOSE: To make a scanning optical system for a laser printer and an optical disk head lightweight and small-sized, by making the beam from a semiconductor laser incident to a hologram lens.
CONSTITUTION: The anisotropic beam from a semiconductor laser 1 is irradiated to a hologram lens 11 obliquely. This beam is diffracted by interference fringes recorded as a hologram and is emitted as an isotropic beam. With respect to the positional relation between the hologram lens and the semiconductor laser, the hologram lens is inclined at an angle θ to the semiconductor laser in a plane including an axis on which the intensity distribution of the semiconductor laser is narrower (normally, in the direction of the junction face). The value of θ is so determined that the emitted beam becomes an isotropic beam.

摘要： PURPOSE:To obtain an inexpensive optical scanner by machining a specular surface to form machining streaks in parallel or inclination to an optical scanning line so that beams of zero order and diffracted beams of higher order do not scan superposedly on the optical scanning line. CONSTITUTION:A reflection surface 2 is so machined that the machining streaks 2' thereof intersect orthogonally with a revolving shaft 8 so that the array of diffracted beams 6' and 7' of higher order intersect orthogonally with a scanning line 4. The line 4 of a scanning beam 5 and the beams 6', 7' scan in parallel apart at a certain space between each other but do not scan superposedly. A shielding plate is provided if the superposed harmful scanning arises by having a time lag on the scanning line of the beam 5 owing to the presence of the diffracted beams of higher order. The plate 9 is provided with an aperture of a fine slit 10 for allowing the passage of only the main scanning beam 5 to shut off the diffracted beams of higher order. The machining streaks are thus allowed to a certain extent and the stage of manufacture is simplified.
