Abstract:
The invention concerns image-recording apparatus, which records an image onto a sheet-film. The image-recording apparatus includes a mainframe; a main/sub-scanning unit that includes a main-scanning unit to expose a light-beam onto a sheet-film by scanning the light-beam in a main-scanning direction and a sub-scanning unit to convey the sheet-film in a sub-scanning direction; and a supporting member to mount and support the main/sub-scanning unit onto the mainframe at a supporting position. The height of the supporting position is substantially the same as that of a center of gravity of the main/sub-scanning unit. The sub-scanning unit is detachably integrated with the main-scanning unit to form the main/sub-scanning unit.
Abstract:
The present invention provides a laser unit using a seal member whose central and peripheral portions will not affect each other to produce strain during mounting and which can be handled as a single component. In the laser unit 100 according to the present invention, a central portion 41 and a peripheral portion 42 of a seal member 40 used are separated from each other by slits 43. Therefore, when the seal member 40 is mounted, the central and peripheral portions will not affect each other to increase strain. In addition, because the central and peripheral portions are connected to each other at several points by bridging portions 44, the seal member 40 can be handled as a single component, which is very convenient.
Abstract:
A driving device for a scanner includes an elongate guiding unit mounted in a base and disposed under an image sensor carriage that extends in a first direction, extending along a second direction transverse to the first direction, and having first and second side rail surfaces transverse to a top rail surface. A roller unit is mounted rotatably on a bottom side of the image sensor carriage, and includes a first roller rotatable about a first axis parallel to the first direction and disposed to roll along the top rail surface, and a second roller rotatable about a second axis transverse to the first and second directions and disposed to roll along the first side rail surface. A spring-loaded retaining unit is mounted on the image sensor carriage, and is disposed to contact rotatablely the second side rail surface. A driving unit drives the image sensor carriage to move in the second direction in the base.
Abstract:
An image reading apparatus includes a spring (15) provided at one end of a reading unit (11) and adapted to bias the reading unit (11) toward an original glass table (10), and a sensor holder (12) provided on a guide rail (14) to be pivotal about it and adapted to hold the reading unit (11) through the spring (15).
Abstract:
A scanner for scanning an object. The scanner comprises a platen, a scanning device, a contact element, a frame and a base. The object is placed on the platen. The scanning device scans the object by a belt driven device. The contact element is disposed between the platen and the scanning device. The base flexibly supports the scanning device toward the platen, providing thorough and regulated distance therebetween.
Abstract:
An isolation system comprising: a substantially rectangular stationary frame; an imaging assembly including a curved platen for supporting image media and an exposure assembly for imagewise exposing a supported image media to produce exposed image media, wherein the imaging assembly has a substantial rectangular footprint and is sized to fit within the stationary frame; and a cable and spring assembly for suspending the imaging assembly from the frame to substantially isolate the imaging assembly from sources of external vibration.
Abstract:
A flat bed image scanner uses a contact image sensor to scan a document. The distance between the contact image sensor and the glass window, over which the document is placed, is minimized and held constant by inserting a lubricating element between the contact image sensor and the glass window. The lubricating element may comprise two pads placed at the two ends of the contact image sensor. The lubricating element can also be integrated structurally with the contact image sensor. The material of the lubricating element can be nylon or some other kinds of plastic. The lubricating element may also comprise two guide rails placed at the two edges of the scan window.
Abstract:
A read module includes: a light source that applies light to an original to read an image; a photoelectric conversion section that converts reflected light from the original into an image signal of the image; and a connector to be electrically connected to a controller connector in a controller. The connector has a plurality of terminals placed side by side in a predetermined direction. The plurality of terminals includes an image signal output terminal section that outputs the image signal to the controller and a power terminal section that inputs electric power for lighting the light source supplied from the controller to the read module. The power terminal section is placed in the proximity of one end of the plurality of terminals in the predetermined direction thereof. The image signal output terminal section is placed in the proximity of an opposite end in the predetermined direction thereof.
Abstract:
An imaging device for setting an image on a printing form by at least one imaging energy source, includes a device for determining a component of a relative movement between the imaging energy source and the printing form whereon an image is to be set. An actuator device moves the imaging energy source in such a manner that undesired components of the relative movement between the imaging energy source and the printing form are reduced. An imaging module may be formed of at least two of the imaging devices. A printing press includes the imaging device or the imaging module. A method sets an image on a printing form.
Abstract:
A vibration attenuating mechanism and method is disclosed for the purpose of maintaining a high quality of image reading or writing while scanning a document with an image processing device which includes a carriage that supports an optical scanning element, a motor which drives the optical scanning element so as to scan a document for either reading or writing data, and a housing which supports the optical scanning element and the motor. At least one of a weight or a vibration absorbing material is provided nearby the motor so as to reduce vibrations which are transferred from the motor to the optical scanning element. In this way, the quality of image reading is maintained despite the recent trend toward increased scanning speeds.
