Abstract: PROBLEM TO BE SOLVED: To provide a small, inexpensive light guide with superior and uniform illumination characteristics, whose power consumption is low and whose effi ciency of light flux emitted by a light source is high. SOLUTION: In a light guide guiding light from a light source in a longitudinal direction and irradiating light, an area diffusing and/or reflecting light from the light source in the longitudinal direction of the light guide is installed, a reflection part is arranged so that a normal passing the center of the width of the reflection part is deviated from the center of a side including the reflection part when it is viewed from a light source in a part of the reflection part, which is comparatively close to the light source, and an inclination face inclined to a face having the reflection part is installed. Thus, reflected light from the reflection part is reduced and illuminance distribution by the light guide is improved with respect to direct light which passes through the light guide and whose intensity is comparatively high and the irradiation characteristics of the whole illumination device are improved. The reflection part is arranged so that a light outgoing face is deviate to a side similar to the normal from the center of the side including the reflection part and illuminance distribution is improved.

Abstract: PROBLEM TO BE SOLVED: To improve the mount accuracy of each member such as a sensor array member and an image forming element by pressing a light guide light source onto a base so as to support the light guide with the base. SOLUTION: A projection 8 is provided to a side of a sensor array base of a light guide member 4. The projection 8 is pressed into contact with the sensor array base 2 to support the light guide member 4. Furthermore, a light emission part 4a of the light guide member 4 is configured to be a lens that collects lights and part of the part 4a is pressed into contact with the sensor array base 2 to support the light guide member 4. The light guide member 4 is fixed by being clamped with a frame 6 and the sensor array base 2. Since a light source 7 is mounted on the base having the photoelectric conversion element in this way not via any frame, the layout of the light source 7 and the photoelectric conversion element is independent of any frame so as to enhance the accuracy of the layout of the light source 7 and the photoelectric conversion element. Thus, the image reader is made small in size.

Abstract: PROBLEM TO BE SOLVED: To uniformly illuminate an irrastrated face with light by forming an area for the reflection/diffusion of a conductor like saw teeth so that teeth are arranged in the longitudinal direction of the rod-like conductor and forming these teeth so that the width of teeth is narrowed in the vicinity of a light source and extended in accordance with separation from the light source. SOLUTION: An area 5 for reflecting/scattering a beam propagated through the inside of the conductor 3 and extracting the beam to the outside of the conductor 3 is constituted so as to form a fine saw tooth-like tooth string on one side face along the longitudinal direction of the conductor 3. The width of the area 5 is set so as to be narrowed in the vicinity of an incident face and extended on a center part separated from any incident face. Since the incident rate of a beam propagated through the inside of the conductor 3 upon the area 5 is reduced on near side of the incident face and increased on the far side, the non-uniformity of illuminance in the longitudinal direction of the conductor 3 is effectively improved.

Abstract: PROBLEM TO BE SOLVED: To make a light conductor uniform in illuminance, low in power consumption and small in size by providing an area for reflecting and diffusing light from a light source along the longitudinal direction of the light conductor in the light transmission body for guiding light form the light source in the longitudinal direction and reflecting the light. SOLUTION: An LED light source 8 is arranged on one end face of the longitudinal direction of the transparent member with a rectangular cross section, and a region 5 formed by a means for making the surface of a part of the member 3 a rough surface, applying a light-diffusing and reflecting paint, etc., is arranged at the part of the member 3 for reflecting/diffusing a luminous flux. A luminous flux, emitted form the light source 8 normally repeats reflection within the member 3 to be propagated inside the member 3 to a reflecting part 6, and then it is returned toward the light source 8. In addition, the luminous flux entering the region 5 in the middle of propagation is diffused and reflected in the region 5 to be irradiated on an original surface being an irradiated surface 42 through an injection part (l1 ). Otherwise, the luminous flux is reflected and propagates within the member 3 (l2 ).

Abstract: PROBLEM TO BE SOLVED: To improve uniformity of illuminance, to reduce power consumption, to reduce the cost and to make the size small by providing an area to diffuse and/or reflect a light from a light source along a lengthwise direction of a light transmission body and deviating a normal passing through the center from a normal passing through the center of the light source in the vicinity of the light source. SOLUTION: A luminous flux from an LED light source 8 repeats usually reflection in a translucent member 3 and propagates through the inside of the translucent member 3 and reaches a reflection section 6 and is returned toward the LED light source 8. Furthermore, the luminous flux made incident onto an area 5 on the way of propagation is diffused and reflected in the area 5 and emitted onto an original face being an emitted face through an emission section (11 ), or reflected and propagated in the translucent member 3 again (12 ). The LED light source 8 is placed while being deviated from the normal passing through the center of the width of the area 5. Since the luminous flux made incident from the LED light source 8 directly onto the area 5 is reduced, the illuminance is high for the LED light source 8 only and the ununiformity of the illuminance in the translucent member 3 is eliminated.

Abstract: PROBLEM TO BE SOLVED: To obtain an emitted light expanded linearly with a sufficient light quantity by arranging a hologram plate recording very small interference fringes with respective wavelength light in 3-dimension so to make a luminous flux of each light source whose wavelength of emitting light differs incident on a light transmission body efficiently even without extending an incident luminous area. SOLUTION: A Lippman type hologram plate 14 is arranged between red, green, blue LED lamps 1a-1c whose light wavelength differs from each other and a light incident face 4 of a light transmission body 3. The hologram plate 14 forms the Lippman type hologram by using the corresponding light of wavelength from the position of the LED lamps 1a-1c to record very small interference fringes of respective wavelength light beams in 3-dimension. The hologram plate 14 converts luminous flux from the LED lamps 1a-1c into one converged light and it is made incident on the light transmission body 3 efficiently.

Abstract: PURPOSE:To reduce the degradation of read images by providing a light scattering member or the like on an optical path from plural light emitting elements or light emitting parts to the surface of an original and respectively distributing light flux radiated from these light emitting elements. CONSTITUTION:The light flux generated from a light emitting part 3a of an EL 3 is reflected by a reflecting member 8, arrives at a light flux scattering member 9, reflected and scattered again here and afterwards, an original 6 is illuminated with the light flux through a lighting window near a photoelectric converting element provided on the surface of a sensor substrate 1. Namely, the light flux from light emitting parts 3a and 3b is reflected by the reflecting member 8, mixed by the light flux scattering member 9 and used as illumination light. In this case, since the light flux arrives at the lighting window after it is scattered and reflected by the light flux scattering member 9 provided just under the photoelectric converting element or the lighting window, the light flux made incident to the lighting window is equally made incident from right and left without making the incidental direction eccentric to one side.

Abstract: PURPOSE:To miniaturize a device and to obtain satisfactory sensor output by providing a photoelectric converter, a light transmissible substrate, a light transmissible supporting body on a plane confronted with an original, and a light source at a side opposite to a supporting plane, irradiating the original with transmitted light, and receiving reflected light by a photoelectric conversion element. CONSTITUTION:A light transmissible sensor 1 is placed at the side confronted with the original 6, and is stuck on the light transmissible substrate (supporting body) 2 with a light transmissible adhesive layer 5. The coefficient of thermal expansion and the light refractive index of the adhesive 5 is approximated to that of the substrate. The sensor 1 is connected to the wiring part 4 of the substrate 2 by soldering, etc. The original is irradiated with the light source 3 transmitting the supporting body and the substrate, and the sensor 1 is irradiated with the reflected light. In such constitution, miniaturization can be easily performed since the light source 3 is arranged on the back plane of the substrate 2. Also, no information light transmits the substrate 2 and the sensor substrate 1. Therefore, loss or diffusion in the light quantity of the information light can be prevented occurring, which improves an S/N, and the satisfactory sensor output can be obtained.
