Abstract:
The invention provides an adjustment jig provided with a pattern for adjusting the direction of a reading line of a scanner which reads a target image line by line, which comprises a holder section for holding the scanner, a first pattern provided adjacent to a target reading line to be read by the scanner when the reading line direction of the scanner held is correctly adjusted, and a second pattern provided adjacent to the target reading line on the side opposite to the first pattern with the target reading line positioned therebetween, the second pattern being different from the first pattern in the brightness of at least one of hues which can be read by the scanner or in the width thereof in the reading line direction.
Abstract:
An image reading apparatus includes a line light source having a light guide plate and red-, green-, and blue-LEDs, for a light transmitting original, and a contact image sensor unit for detecting light from the line light source. The light transmitting original is arranged between the line light source and the contact image sensor unit. The light transmitting original is read by moving the line light source and the contact image sensor unit relative to the light transmitting original. The line light source is moved interlockingly with the contact image sensor unit by the attraction between a magnet provided at both ends of the line light source in the longitudinal direction thereof and a magnet provided at both ends of the contact image sensor unit in the longitudinal direction thereof.
Abstract:
A method and mechanism to set a platen glass of an image reader by demounting the platen glass after the platen glass has previously been position-adjusted and positioning means have been fixed to this adjusted position and then achieving the desired positioning by these positioning means before the platen glass is mounted again on the image reader. Upon completion of optical adjustment, the platen glass is temporarily fixed to a casing of the image reader and then the platen glass is position-adjusted until image data formed on a test chart sheet coincide with predetermined image data. After the adjustment, positioning blocks are secured to top-plates of the casing and a glass retaining plate is secured to these top-plates. Subsequently, the platen glass may be mounted on the image reader in operative association with these positioning blocks to set the platen glass to the adjusted position.
Abstract:
A kind of position set structure of scanner transmission components, wherein the holder is used to set the transmission components is molded at an adequate position of the case bottom. Besides, there are several position set axes molded on the holder and these axes have mushroom head and set seat used to locate the transmission components like gears easily and fast. Besides, on one side below the holder there is a open channel and S guard used to clip the flat cable. So, the structure originally needing several components is reduced to less components and the assembly time and difficulty is also reduced. In operation, it has easy structure, fast assembly and less cost function.
Abstract:
An image capturing apparatus for capturing a sequence of subsections of a flat field subject image. The image capturing apparatus includes a camera assembly, preferably including a digital camera, and a lighting assembly. The image capturing apparatus further includes an image positioning jig for moving the subject image to a series of predetermined positions relative to the camera assembly for the capture of the subsections of the subject image by the camera. The image positioning jig includes a backing plate for supporting the subject image in an image plane, and a positioning rail for abutting an edge of the subject image for slidable movement along the X-axis of the image plane. A plurality of rail locators are arranged on the backing plate for attaching the positioning rail to the backing plate at predetermined positions along the Y-axis of the image plane. A plurality of image stops are disposed on the backing plate for positioning the image at predetermined locations along the X-axis of the image plane.
Abstract:
The present invention discloses a new CIS information reading apparatus which employs rolling elements interposed between a sheet table and a CIS module for allowing the CIS module to roll over the bottom surface of the sheet table in linear direction. The CIS module is mounted on a pair of supports which uplift the CIS module in a manner that the CIS module presses tightly on the rolling elements to roll over the bottom surface of the sheet table. The pair of supports move along a pair of U grooves for guiding the CIS module along the sheet table. Since the rolling elements and the sheet table remain point or line contacts, so the friction between the CIS module and the sheet table will be very small. This helps to improve the picture duality of the images generated by the CIS module.
Abstract:
According to a precision assembly technique, a first subassembly is precisely aligned relative to a plurality of alignment features in an alignment fixture and at least three non-coplanar flexures having complementary alignment features are located with respect to corresponding alignment features on the alignment fixture and mechanically attached to the first subassembly. The first subassembly with the attached flexure sheets is removed from the alignment fixture and located with respect to a second subassembly having a plurality of alignment features identical to the alignment features in the alignment fixture using the alignment features on the second subassembly and the complementary alignment features on the flexure sheets to precisely align the first subassembly with the complementary alignment features on the second subassembly. The flexure sheets are then mechanically attached to the second subassembly, whereby the first and second subassemblies are aligned and rigidly connected to one another.
Abstract:
In a two-carrier type image scanner, a first carrier (10) is moved in parallel to a document surface at a scanning speed and a second carrier (20) is moved at half the scanning speed, the image scanner optically reading out image information such as figures and characters on the document surface using an optical system mounted on the two carriers. To permit the adjustment of the carrier in the roll direction to be easily conducted, one side of each of the carriers (10, 20) is movably engaged with a fixed guide shaft (46), and the other side is guided by a bearing (53) which rolls on a fixed guide rail (47) disposed in parallel with the guide shaft (46), wherein the carrier is capable of being adjusted in the roll direction with respect to the guide shaft (46) when a position of the bearing (53) with respect to the carrier is adjusted.
