Abstract:
A variable reflectance cover for a scanning system. The cover comprises a backing moveable through a plurality of positions. Moving the backing through the plurality of positions varies the reflectance of the cover. In one embodiment, the backing is an endless rotatable belt. In a second embodiment, the backing is a removable panel having a first side with a first reflectance and a second side with a second reflectance. In yet a third embodiment, the backing includes polarizers placed adjacent to a reflective panel. Rotating one polarizer relative to another varies the reflectance of the cover.
Abstract:
A first light source is adapted to illuminate a first object with first light. A first sensor includes a first light receiving element adapted to detect the first light by way of the first object. A second sensor includes a second light receiving element adapted to detect a second light which is externally inputted by way of a second object. A transparent member is disposed on at least one of a first optical path extending from the first object to the first sensor through a first lens and a second optical path extending from the second object to the second sensor through a second lens.
Abstract:
In an image reading apparatus that can read a reflection original and transparent original, a film holder for holding the transparent original is provided to be pivotal to the left or right about a shaft as the center. After the transparent original is set such that its image can be seen correctly, when the film holder is brought down to the right, the film can be set correctly concerning its upper and lower sides. At this time, as the film holder is held by the reading apparatus, its positional shift can also be prevented.
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:
The present invention is to provide an image scanner, for scanning a reflection document or a transmission document. The image scanner comprises a shell, a document window glass, a transmission document carrier, and an optical chassis. The shell has a groove on its upper surface. The document window glass is capable of connecting with the groove, for scanning the reflection document. The transmission document carrier is capable of connecting with the groove, for scanning the transmission document. The optical chassis is provided at a proper location, for retrieving the images of the reflection document and the transmission document and converting them to an electronic signal. Wherein, by placing the document window glass or transmission document carrier into the groove, the image scanner is capable of scanning the reflection document or transmission document, respectively.
Abstract:
The scanning method of the invention enables a user to scan transparencies with a duplex scanner having a moveable camera, and a mirror or light source associated with the camera on each side of the document path. The scanner, in its normal mode of operation, is a duplex reflective scanner which means the image, per side, is captured by reflecting light from a light source located on the same side of an opaque flat object as the CCD of the camera that captures the image. In order to scan transparencies, a mechanism is provided which allows an opposing camera light source to be aligned (moved at runtime) with the aperture of the camera opposite the opposing camera light source. This allows the light of the opposing camera light source to project through a transparent object while the opposite camera CCD captures an image of the transparency. The opposite camera, which captures the image, has its light source turned off while in the transparent scanning mode.
Abstract:
A TMA includes a housing, a light module and a light guide. The light module and the light guide are received in the housing. The top of the housing is provided with a preview window whose location is set corresponding to a rest position of the light module. The light guide receives the emitting light of the light module and delivers the light to the preview window.
Abstract:
In order to switch to a light source with a light amount corresponding to the type of original from among a plurality of light sources in a simplified structure without using a specific switching mechanism in reading a transmissive original with a photoelectric sensor while moving, there are provided a platen on which an original is mounted, a line sensor that performs photoelectric conversion on light from the original on the platen, a first carriage that moves along the platen and guides the light from the original to the line sensor, a first housing that stores and supports the first carriage to be movable along the platen, first driving means for moving the first carriage, a second carriage provided with a plurality of rod-shaped light-source lamps that applies light to the original, a second housing that stores and supports the second carriage to be movable along the platen and covers the platen, second driving means for moving the second carriage, and control means for controlling the first driving means, the second driving means and lighting of the plurality of light-source lamps, where the plurality of light-source lamps is spaced in parallel with one another in the moving direction of the second carriage, and due to a signal from means for selecting a single light-source lamp from the plurality of light-source lamps corresponding to the type of the original, the control means controls to move the first carriage from a standby position to a predetermined position, further move the second carriage from a standby position by an amount of movement set corresponding to the selected light-source lamp to position in the predetermined position, and then, move the first carriage and the second carriage at the same speed from the predetermined position to a reading start position of the original.
Abstract:
Images obtained by prescanning a transparent original by an image reading apparatus are output from a printing apparatus as a navigation sheet on which the images are laid out together with additional information fields. The navigation sheet containing additional information is read, and the additional information is recognized. The transparent original which is left after prescanning is scanned, and printing is performed on the basis of the recognized additional information. This makes it possible to print out a desired image under desired conditions from the transparent original, in which a plurality of images are recorded, by operating a single apparatus without any external device such as a host computer.
