Abstract:
An image sensor and a facsimile apparatus incorporating the same. A sponge piece is attached to a substrate with a light receiving device attached thereto. The sponge piece is brought into contact with an inclined inner wall surface of the frame when the substrate is mounted on the frame. The sponge piece thus urges the substrate in the vertical direction and sideways, thereby fixing the substrate at a predetermined position. Since the light receiving device is prevented from any deviation in the horizontal and vertical direction, a good picture quality is obtained.
Abstract:
An image sensor and a facsimile apparatus incorporating the same. The upper surface of a substrate with a light receiving device attached thereto is pushed upward so as to fix the substrate to a frame. Since the substrate is fixed to the frame at the upper surface of the substrate, it is easy to adjust the focus of an optical system on the light receiving portion.
Abstract:
An image sensor has a frame including a reading window formed therein at the top of the frame. The reading window is closed by a glass covering which is adhered to the frame through an adhesive. First and second grooves are provided in the frame to extend along the reading window. After the adhesive has been charged into the first groove, the glass covering is placed and pressed against the frame top so that the glass covering will be adhered to the frame top through the adhesive. At this time, any excess adhesive may be received and held by the second groove.
Abstract:
An image reader A1 according to the present invention comprises a pair of light source devices 3, a light guide member 4, a first and a second reflectors 7A and 7B, a plurality of light receiving elements 5, and a case 1. The image reader A1 further includes a first fitting contrivance 71 for positioning the first reflector 7A relative to the case 1 by inserting the first reflector 7A into the case 1 in the insertion direction z, a second fitting contrivance 72 for positioning the light guide member 4 relative to the case 1 by inserting the light guide member 4 into the case 1 in the insertion direction z, and a third fitting contrivance 73 for positioning the second reflector 7B relative to the case 1 by inserting the second reflector 7B into the case 1 in the insertion direction z.
Abstract:
An exposure device includes plural light-emitting elements, a light amount detection unit, a controller, plural holding units and a connection unit. The controller sequentially determines control values of the light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value. The holding units are provided for the light-emitting elements, respectively. Each holding unit holds a control voltage of the controller. When the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plural light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.
Abstract:
An image capturing device has a base plate with a solid-state optical sensor mounted on the top surface. The base plate has a plurality of apertures defined therethrough. A glass frame is detachably mounted on the base plate and has an opening defined therethrough and a piece of glass mounted at the upper end of the opening. A lens retainer is detachably mounted on the glass frame and has a tubular portion with a hole in alignment with the optical sensor, a male thread formed at an outer periphery of the tubular portion; and an adjusting ring covering the tubular portion and having a female thread engaged with the male thread on the tubular portion and a lens installed therein.
Abstract:
A contact-type image sensor having an adhesive elastic layer therein includes a protective member including a light transmitting area. An illumination device is provided for illuminating an original, bearing image information thereon, through the protective member. A photosensor device is provided for reading the image information, and imaging structure is provided for focusing light reflected from the original onto the photosensor device. Support structure is provided for integrally supporting the illumination device, the photosensor device, and the imaging structure. An elastic adhesive layer is provided on a contact surface between the protective member and the support structure. The elastic adhesive layer joins the protective member and the support structure.
Abstract:
Light-shielding layers are adhered to the lower surface of a glass plate, spaced apart from each other and defining a slit having a width of L. An array of rod lenses is located below the glass plate, such that the optical axes of the lenses pass through the slit. The lower surface of the glass plate is generally covered, and exposed via the slit only. Hence, the leakage of lights reflected from points near a reading position into each photoelectric conversion element is minimized, whereby the element outputs a pixel signal faithfully representing that part of the image which is located at the reading position.
Abstract:
An image-reading device comprises a lens unit array comprising an array of distributed refractive index plastic cylindrical lens elements and plastic plates, adhering the distributed refractive index plastic cylindrical lens elements therebetween, and a plastic case containing and holding the lens unit array. The difference in the thermal expansion coefficients of the plates of the lens unit array and the plastic case is 5.0.times.10.sup.-5 cm/cm/.degree. C. or below, or more preferably, 3.0.times.10.sup.-5 cm/cm/.degree. C. or below. The plastic case is formed by connecting, in a longitudinal arrangement, a plurality of case segments formed by an injection molding.
