Abstract:
The objective of the present invention is the easy removal, from an opening in a support base, of a document support plate. A document reading unit according to this invention includes an image sensor, for reading a document; a support base having a box-like shape, for internally accommodating and supporting the image sensor, and an opening through which the image sensor faces a document; a contact glass that is located at the opening, for covering the image sensor and supporting a document that is being conveyed to the image sensor; glass support members linked with the contact glass and arranged on the support base, for supporting the contact glass; and fixing screws, for detachably fixing the glass support members to the support base.
Abstract:
An image reading device capable of correctly reading an image on a document is provided without the need to increase the size of an upper cover, etc. of the device. A CIS (Contact Image Sensor) is supported by holders and support shafts to be movable toward the upper cover (rib) and is biased toward the rib by compression springs. In this configuration, the rib for holding the document is not required to be installed as a movable component and there is no need to provide a space for allowing the rib to move or providing the upper cover with a mechanism for allowing the rib to move, which can avoid the need to increase the size of the upper cover.
Abstract:
A mirror holding apparatus, disposed in a chassis of a scanner, is disclosed. The mirror holding apparatus includes two opposite holding bases and more than one pair of holding plates, for holding the mirror and providing various angles or directions of inclination of the mirror. The pairs of holding plates are not parallel to any other. When the light reflected from the mirror on one pair of holding plates deviates from the original optical path. A substitute mirror hanging at the substitute pair of holding plate can be used to adjust the deviated optical path. Therefore, the wasting of material is avoided and the time and labor for producing a new holding base is saved.
Abstract:
A light-emitting unit 20 has a light-emitting unit board 21 made of resin provided with a lead frame 22. The light-emitting unit board 21 is also provided with an open window 21a for mounting a light-emitting device. The lead frame 22 comprises a lead terminal section 22a, an inner lead section 22c, and a light-emitting device mounting and connecting section 22b which is exposed within the open window 21a. The light-emitting devices 23a, 23b, and 23c are bonded with the light-emitting device mounting and connecting section 22b, and electrodes of the light-emitting devices and the lead frame are connected by a metal wire 24, wherein the open window 21a is sealed by transparent resin. The lead frame 22 is made of iron-containing copper to improve heat radiation performance of the light-emitting unit board. By increasing maximum current to be supplied to the light-emitting diodes, it is possible to increase illumination brightness and to attain speedup of image reading.
Abstract:
A high speed imaging apparatus for CCD based scanners comprises a housing having separate compartments which complement modular assemblies installed therein. A decoder compartment houses components associated with locating and decoding an image. An optics compartment houses the mirrors and associated optics for reflecting the subject image onto the CCD detector. A lighting compartment includes high intensity lamps and the associated components for illuminating an object to be imaged. The lighting compartment includes a heat management system which removes the heat from the high intensity lamps and prevents heat from migrating to other compartments within the housing.
Abstract:
In a color image readout device having a plurality of light sources of different color emissions, controlled to light sequentially so that light reflected from a document irradiated by the light sources is fed to a CCD sensor to obtain a color separation signal, the plurality of light sources are arranged on a single light source support to form a single unit.
Abstract:
An image reading apparatus configured to read an image of an original, including: a light source configured to irradiate the original with light; an optical system configured to condense and image a light beam from the light source reflected from the original; a substrate member having a photoelectric conversion unit; a fixing member fixed to the substrate member; a support member configured to support the optical system; and an adhesive bonding the fixing member and the support member together, wherein one of the support member and the fixing member has a protruding portion which protrudes toward the other of the support member and the fixing member, the other has a recessed portion opposed to the protruding portion, the protruding portion protrudes in the recessed portion in a non-contact state to maintain a gap between the protruding portion and the recessed portion, and the adhesive is applied to the gap.
Abstract:
A solid-state image pickup device comprising: a multilayer wiring board 2 having an opening portion 21; a spacer 3 covered with a conductive film 32, and fixed to the multilayer wiring board 2 in a state of making the conductive film 32 face contact with a reference potential electrode exposed into the opening portion 21 of the multilayer wiring board 2; a solid-state image pickup element 4 fixed to the spacer 3 in a state of face contact with the conductive film 32 of the spacer 3, and arranged in the opening portion 21; and an optical element 5 fixed at a position opposing the solid-state image pickup element 4 via the spacer 3, and transmitting light into the opening portion.
Abstract:
An imaging system (60) comprises a housing (200) with reference surfaces (274,276), a lens (570) in contact with the reference surfaces (274,276), a member (600) retained to the housing in contact with the lens, and a spring (720) located between and in contact with a portion (282,332,342) of the housing and the lens. In a first operating condition, the member (600) is retained to the housing at a first location (350,360,370,380) and the lens is translatable with respect to the housing (200) and in a second operating condition, the member (600) is retained to the housing at a second location (420,424) and the lens is not translatable with respect to the housing.
