    Abstract: An image reading apparatus includes a sheet conveyance path on which a sheet of a document from which an image is to be read is conveyable; a light source that emits light to be irradiated on the sheet; a conductive unit through which heat generated at the light source is transferable; and a heat radiating unit that forms a part of the sheet conveyance path, through which the heat transferred from the light source to the conductive unit is propagable, and that radiates the heat propagated from the conductive unit to air flowing in the sheet conveyance path when the sheet is being conveyed.

    Abstract: There is disclosed a method for providing precise color-to-color registration of color dots in a multicolor proof with a thermal printer comprising a CPU and Printer Controller, a Motion Controller, a writing drum, and a writing head coupled to a translation means. Using the disclosed method, a proof and a dye donor member with a predetermined dye color thereon are mounted on the writing drum. The writing head is then moved to a predetermined start position defined by a sensor at a predetermined position along the translation means which has its optical path blocked by the writing head. The writing head is then moved forward to a predetermined home position which is defined by a next subsequent pulse from a multi-pulse radial position-indicating encoder coupled to the translation means occurring after the writing head leaves the start position. In sequence, the writing drum and then the translation means are accelerated with a separate predetermined substantially constant acceleration until a separate predetermined velocity is obtained. After the predetermined velocity of the translation means is obtained, the printing of color dots on the proof is started upon the receipt of a next subsequent pulse from a multi-pulse radial position-indicating encoder coupled to the writing drum. 1. A method of printing color dots on a multicolor proof with a thermal printer comprising a rotatable writing drum and a writing head which is coupled to a translation means comprising the steps of: (a) activating the translation means for moving the writing head to a predetermined fixed start position; (b) moving the writing head in a forward direction to a home position defined by the detection of a next subsequent pulse from a first radial position encoder coupled to the translation means after the writing head has reached the predetermined fixed start position in step (a), and simultaneously therewith stopping the movement of the translation means and the writing head, where the first radial positional encoder produces a predetermined plurality of pulses per revolution of the translation means; (c) accelerating the writing drum with a substantially constant acceleration to a predetermined velocity in response to the receipt of the next subsequent pulse from the first radial position encoder in step (b); (d) accelerating the translation means with a predetermined substantially constant acceleration to a predetermined velocity in response to the writing drum reaching the predetermined velocity in step (c); (e) selectively energizing a predetermined number of thermal elements in the writing head for starting the printing of color dots of a dye color onto a receiver member mounted on the writing drum in response to the writing drum reaching a predetermined radial position after the translation means has reached the predetermined velocity; and (f) repeating steps (a) through (e) for each other dye color needed to print the multicolor proof.

    Abstract: PURPOSE:To unnecessitate the correction circuit by reducing the variability of bit signals by a method wherein the refractive index is continuously changed in the film thickness direction, and the refractive index of a photoconductive layer in the neighborhood of the substrate surface is set at 3.2 or less in the light of 6,328Angstrom wavelength. CONSTITUTION:In this photosensor, the photoconductive layer has the refractive index continuously changing, with respect to the film thickness direction, at least in part in the film thickness direction. Besides, the refractive index of this photoconductive layer in the neighborhood of the substrate surface is 3.2 or less in the light of 6,328Angstrom wavelength. In other words, the photoconductive layer is made of amorphous material, and an a-Si underlay layer 2 have a refractive index of 3.2 or less. An a-Si layer 3 has a refractive index of more than 3.2, preferably approx. 3.4. Such a photoconductive layer can be formed by suitably setting such conditions for glow discharge by reactive sputtering or ion plating as discharge power, substrate temperature, composition of raw material gas, and pressure of raw material gas.

    Abstract: PURPOSE:To improve adhesive properties between a photoconductive layer in a photosensor for a picture reader and a substrate by continuously changing the refractive index of the photoconductive layer in the direction of film thickness. CONSTITUTION:A photoconductive layer consists of an amorphous material mainly comprising a-Si, and the refractive index of an a-Si undercoat layer 2 extends over 3.2 or less in the beam having a wavelength of 6,328Angstrom . In the a-Si undercoat layer 2 adjacent to a base 1, adhesive properties with the base body 1 can be kept excellent by conducting glow discharge by discharge power such as comparatively large one and forming a layer having small stress. A section, a refractive index thereof continuously changes in the direction of film thickness while gradually reducing discharge power is shaped, and an a-Si layer 3 having a comparatively large refractive index is formed. It is preferable that the thickness of the undercoat layer 2 extends over 1,000Angstrom or less when beams are projected from the base body 1 side and the device is used. The a-Si undercoat layer 2 for the photosensor array has action as a stress relaxation layer, thus improving adhesive properties between the substrate and the photoconductive layer.
