Abstract:
An image reading device includes a document mounting plate having a mounting surface and a rear surface, and an image reading unit. The image reading unit includes a photoelectric converter facing the rear surface, a case to hold the photoelectric converter, and at least one first rotating member and at least one second rotating member that rotate and receive a pressing force from the rear surface of the document mounting plate as the image reading unit moves. The image reading unit also includes a holder configured to support the case and at least one urging device positioned between the holder and the case. The at least one urging device urges the case toward the rear surface, and exerts an urging force opposite to the pressing force, and balances against the pressing force.
Abstract:
In a color marking assembly, a series of ROS units are aligned above a photoconductive surface. These units have inboard and outboard mounts connecting them to this assembly. The inboard mounts are attached to a first side of the ROS, and the outboard mounts are attached to a second side of the ROS unit.The inboard mount is an elongated bar extending beyond the height of the ROS unit. This elongated bar has hinged portions on both its top and bottom connections to the ROS unit. The outboard mount has a ball bearing or sphere configuration. This configuration and the inboard mount enable the ROS unit to be easily deskewed when required.
Abstract:
The present invention is a flatbed scanner operating with a digital image capture module comprising two-dimensional (2D) optical image photo-sensor and in particular with a digital camera or digital video camera. The present invention further relates to flatbed scanners and means and methods of supporting cameras, and particularly, although not exclusively, to a flatbed scanner housing for holding a digital camera to allow the digital camera to act as a document capture device in obtaining digital images suitable for downloading to a personal computer or other computer peripherals such as a printer. The scanner incorporates an image capturing module comprising 2D image photosensor and assembly such as flash light, electronic circuit, and software inside the flatbed scanner box to function like an image capturing module where said scanner box functions like the camera body with an internal lens internal.
Abstract:
A scanning module includes a contact image sensor unit and a supporting base. The contact image sensor unit has a top surface, a bottom surface, a front surface and a back surface. The supporting base has a guiding portion, a positioning board mounted on the guiding portion, the two sides of the positioning board extends sideward and bends upward to form an elastic arm respectively, the contact image sensor unit is placed on the positioning board and the elastic arm elastically contacts the bottom surface of the contact image sensor unit. The two sides of the supporting base of the scanning module have an elastic arm respectively, the elastic arm contacts the contact image sensor unit directly and makes sure that the contact image sensor unit contacts the glass tightly.
Abstract:
An image reading device, including: an image sensor which includes a case having an elongate configuration and light-receiving elements arranged in a row in a lengthwise direction of the case and which reads an image; a carriage on which is mounted the image sensor; a guide member which supports the carriage at a support position that corresponds to a substantially lengthwise middle of the image sensor, for guiding a reciprocating movement of the carriage; a pulling member connected to the carriage at a connect position which is determined such that a vertical line from the connect position passes the guide member; and a drive mechanism which reciprocates the pulling member along the guide member.
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:
An image reader for optically reading an image on an original and an image sensor unit for mounting to the image reader. The image sensor unit is provided with a shaft used for rotatably mounting the image sensor unit to an image sensor unit holding member of the image reader. This reduces the size of the image reader.
Abstract:
The compact design of a CIS device is exploited, resulting in a more compact scanning mechanism and in lighter and smaller scanning devices. The CIS is incorporated into a drive belt attached to the length of the CIS. The CIS is forced to traverse the document by a drive mechanism that pulls the entire belt and CIS across the document while maintaining the tension necessary to keep the document in the narrow depth of focus. This mechanism provides a uniform force on the CIS, reducing the possibility of yawing motion, and keeps the document in focus through the tension on the drive belt. The combined CIS and transport mechanism power requirements can be supplied by standard computer interfaces, requiring no additional power supplies. This new mechanism also hides the internal workings of the scanner behind a drive belt that is the size of the platen window. The drive belt can either be printed to present the operator with instructions or markings to indicate document placement or with other information, or the drive belt can be left blank to present the operator with a cleaner and less cluttered scanning device.
Abstract:
A document-guiding device that clips onto the image sensor of a document scanner ensures that documents to be scanned are introduced into the scanner at an optimal angle and are applied to the transparent surface of the image sensor at an optimal pressure, thereby avoiding scratching and soiling the sensor glass surface. Moreover, the deep input guide clip includes a sharp edge that acts as a scrapper to remove or flatten protruding impurities to further reduce soiling the sensor transparent surface. The deep input guide clip has the added benefit of stopping parasitic ambient light and protecting the image sensor against hard falling objects thus avoiding breakage of the transparent surface. The deep input guide clip forms a compact enclosure that may also hold a set of document proximity sensors and associated control electronics for precisely detecting the leading edge of the document when it is introduced in the scanner, its width and its trailing edge.
