Abstract:
[PROBLEMS] To provide a light emitting unit which can efficiently emit light irrespective of opening window shape of a light emitting element substrate frame material, and a lighting apparatus, an image sensor and an image scanner using such light emitting unit. [MEANS FOR SOLVING PROBLEMS] The light emitting unit is provided with a light emitting element; a light emitting element substrate whereupon the light emitting element is mounted; and the light emitting element substrate frame material having an opening window for exposing the light emitting element. The inside of the opening window is sealed with a first resin and a second resin, and a ratio of the first resin to the second resin becomes smaller as it goes to a light emitting window external from the light emitting window inside. The first resin is a transparent resin and the second resin is a colored resin having a high luminosity or a resin including a light reflecting and/or scattering material. Since a cross section boundary between the first resin and the second resin is a curved line, among the light emitted from the light emitting element, the light reflected on an opening window bottom plane can be also efficiently projected to the external.

Disclosed is a light-emitting unit for illuminating devices which is excellent in heat dissipation performance. Specifically disclosed is a light-emitting unit comprising a light-emitting element, a light-emitting element substrate for mounting the light-emitting element, a light-emitting element substrate frame having an open window for exposing the light-emitting element, and an electrode for feeding electricity to the light-emitting element. This light-emitting unit is characterized in that the light-emitting element substrate is made of a metal and the light-emitting element is directly mounted on the light-emitting element substrate. The light-emitting unit is alternatively characterized in that the light-emitting element substrate is made of a metal, a metal oxide film is formed on the light-emitting element substrate, and the light-emitting element is mounted on an electrode formed on the metal oxide film.
Abstract:
Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.
Abstract:
PROBLEM TO BE SOLVED: To provide an image reader in which even if a passing speed changes with time by wear etc. of a transport roller when a manuscript passes each of read locations with respect to both front and rear faces a read magnification of an image can be held same with respect to both the front and rear faces of the manuscript. SOLUTION: Reference images on both front and rear faces of a reference manuscript which is transported on a transport path 3 are respectively read by a first image read part X1 and a second image read part X2, to obtain a first reference read image and a second reference read image, and read cycles of the first image read part X1 and the second image read part X2 are set based on a difference of a change in a sub-scan direction of these reference images.

Abstract:
In a picture reading apparatus, in the pre-scan, an approach is employed to control a CCD line sensor 5 and a film carrying roller 103 so that plural pictures recorded on an optical film 1 are read at a predetermined sampling rate in order from the latest frame to generate frame position data indicating position of left and right ends of frame, etc. Further, in the main scan, an approach is employed such that, in controlling the CCD line sensor 5 and a film carrier 100 so that plural pictures recorded on the optical film are read at a sampling rate higher than the predetermined sampling rate in order from the oldest frame, the reading start and end timings of the CCD line sensor 5 are controlled on the basis of frame position data obtained by the pre-scan. As a result, in this picture reading apparatus, it is possible to precisely obtain picture data of picture of frame in the state where no positional shift takes place. In addition, since the pre-scan is carried out at a low sampling rate, frame position data can be obtained in a short time.
Abstract:
PURPOSE:To equalize the characteristics of a photosensor while increasing the speed of reading by continuously changing the refractive index of a photoconductive layer in the sensor constituting a picture reader in the direction of film thickness and bringing a refractive index in beams having a wavelength of 6,328Angstrom to 3.2 or less in a section in thickness of 1,000Angstrom or less in the vicinity of the surface of a substrate. CONSTITUTION:An a-Si layer 2 as an undercoating layer having a refractive index of 3.2 or less at a wavelength of 6,328Angstrom and an a-Si layer 3 having a refractive index of 3.2 or more, preferably, approximately 3.4, are laminated and formed onto a quartz substrate 1, an ohmic contact layer 4 is shaped to the peripheral section of the surface of the layer 3, and a common electrode 5 is formed to one and a discrete electrode 6 to the other, thus manufacturing a photoelectric conversion section 15. Conductive layers 7 and 8 are shaped onto the substrate 1 while being adjoined to the section 15, the whole surface containing the layers 7 and 8 is coated with an insulating layer 9, and section corresponding to the layer 7 is used as a charge storage capacitor section 13. A semiconductor layer 10 is laminated onto the layer 8, ohmic contact layers 11 are formed at both end sections of the surface of the layer 10, and signal extracting lines 12 are connected to the layers 11, thus using the section as a switching transistor.
Abstract:
An image sensor has a supporting member for integrally supporting a reading system including illuminating means for illuminating an original document, a photoelectrically converting means and imaging means for imaging light reflected by the surface of the original document onto the photoelectrically converting means, and has a member disposed on the side surface of the supporting member. The image sensor has two or more substantially independent spaces formed in the supporting member. The illuminating means, the imaging means and the photoelectrically converting means are accommodated in one of the spaces.
Abstract:
The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image. In particular, the apparatus comprises a rotation detecting section (rotary encoder) (6r) for detecting angular travel rates of the image recording medium (6a); and a recording timing control section (5) for controlling recording timing (HSYNC) at which the image is started to be recorded in the direction perpendicular to the rotational direction of the image recording medium (6a), on the basis of the angular travel rates detected by the rotation detecting section (6r).
