摘要： PROBLEM TO BE SOLVED: To provide an image forming device where dust or dirt adhering to the surface of a reflection mirror is removed every time image forming operation is performed and which has excellent serviceability and maintainability. SOLUTION: A brush-like cleaning part 36 having a brush whose edge part is curved is attachably/detachably installed on an inner cover 34 out of an effective image area below a housing 12 adjacent to a contact glass 10. Since the cleaning part 36 is positioned in parallel with the 1st reflection mirror 18 on the traveling path of a 1st traveling body 20 on which the mirror 18 is mounted, the curved edge of the brush of the cleaning part 36 comes in contact with the surface of the mirror 18 so as to sweep the surface of the mirror 18 like a broom every time the traveling body 20 travels, that is, every time copying operation is performed by a digital copying machine. Thus, the dust adhering to the surface of the mirror 18 is easily removed.

摘要： PROBLEM TO BE SOLVED: To appropriately measure the quantity of light without unnecessarily diffusing the light from a light source. SOLUTION: The light which is irradiated from R-LED, G-LED, and B-LED to a reflecting mirror 64 in which a reflecting film is formed on a surface of a transparent body is reflected by the reflecting mirror toward an LCD. The reflecting mirror is provided with transmission areas 90R, 90G, 90B in which a large number of pin holes 90A are formed at random in an area to reflect the light toward the LCD. A part of the light irradiated on the pin holes of the light irradiated by the reflecting mirror transmits the transparent body. A light quantity sensor 92 is arranged on a back side of the reflecting mirror, and the quantity of light can be appropriately measure through irradiation of the light transmitting the pin holes onto light-receiving elements 94R, 94G, 94B of the light quantity sensor.

摘要： PROBLEM TO BE SOLVED: To enhance the radiating efficiency of heat by closely bringing a reflector into contact with a supporting body without using a fitting screw and improving heat conductivity to the supporting body from the reflector. SOLUTION: A plate part 22b and a plane part 22c mutually orthogonally crossed at the lower part of the back surface of the reflector 22 and on the back surface side of the bottom surface thereof are formed. Besides, an elliptic part 22d is continuously formed at the upper part of the plate part 22 and an elliptic part 22e is continuously formed in front of the plane part 22c. Then, an aperture part 22a is formed at the elliptic part 22d. On the supporting body 23, a plane bottom surface part 23a with which the outside surface of the plane part 22c of the reflector 22 is brought into contact is formed. Besides, bent parts 23c and 23d are formed on the back surface side of the bottom surface part 23a and end part of the bent part 23d is made to abut on the outside surface of the upper end part of the plate part 22b of the reflector 22. The part of the end of the bent part 23d facing the aperture part 22a of the reflector 22 is provided with a projecting piece entering the aperture part 22a of the reflector 22 from in a back surface direction and abutting on the lower edge part of the aperture part 22a from the upper surface side.

摘要： PROBLEM TO BE SOLVED: To reduce the number of parts and reduce the size of the whole of a device by focusing output light from a halogen lamp or deflecting a laser beam via a both-sided mirror. SOLUTION: This optical device 10 includes a halogen lamp 12 and a semiconductor laser 14, and a both-sided mirror 26 is laid so as to be related to both of the lamp 12 and laser 14. Also, when the halogen lamp 12 is activated, the output light thereof is reflected on one side 26a of the both-sided mirror 26 and focuses on the prescribed document reading position. Then, the optical image of a document 20 is incident on a photosensitive body 24 via a lens 22. On the other hand, when the semiconductor laser 14 is activated, a laser beam as output therefrom is deflected with the other side 26b of the both-sided mirror 26 and introduced to the prescribed position of the photosensitive body 24.

摘要： PROBLEM TO BE SOLVED: To secure high parallel lines and to enhance the utilization efficiency of energy by using a cylindrical light source as a light source, setting a slit in a direction parallel with the cylindrical light source and forming a linear irradiation surface on a carrying part. SOLUTION: In order to irradiate a work on the carrying part 70 with a directly projected irradiating light beam 60 at an appropriate collimation half angle θ by using the cylindrical light source 10 such as a fluorescent lamp, the 1st slit 40 and the 2nd slit 50 are formed in order from the light source side between the carrying part 70 and the light source 10 so that a line linking the center of the slit and the center of the light source 10 may be perpendicular to a carrying surface. Furthermore, in order to utilize the light beam emitted from the side surface of the light source 10 for exposure, the light diverged in a direction parallel with a carrying direction is reflected on reflection mirrors 20 and 30 provided on both sides of the light source 10 and the angles of the mirrors 20 and 30 are adjusted so that the reflected irradiating light beams 62 and 64 may be perpendicular to the carrying surface. In such a case, it is necessary to set the mirrors 20 and 30 to 45 deg. clockwise and counterclockwise with respect to the carrying surface.

摘要： PROBLEM TO BE SOLVED: To easily and accurately perform dodging in a photographic printer where photographic paper is housed in the body of the title printer. SOLUTION: Illuminating light whose color balance and intensity are adjusted by a dimmer 11 illuminates a digital micromirror device 2. In the device 2, micromirrors very small in size and freely swingable are arranged in a matrix state, and spot light is reflected toward a lens 20 or a light absorption plate 25 in accordance with the tilt angle of the micromirror. In monitoring, the spot light reflected by all the micromirrors goes toward the lens 20, so that the respective parts of a frame are dividedly illuminated with the spot light. The micromirror illuminating a range where dodging is not performed continuously reflects the spot light toward the lens 20 in the midst of printing. The micromirror illuminating a dodging range reflects the spot light toward the lens 20 at the beginning of printing but reflects the spot light toward the light absorption plate 25 because the tilt is changed in the midst of printing. Since illumination is stopped in a dodging range, projection to the photographic paper 23 is finished in the midst of printing. Exposure is reduced in the dodging range, so that the density of a printed photograph is lowered.
