Abstract:
Accessories for a device used for reading a latent image recorded on an image plate by means of X-radiation. The device comprises: a drum element (8), having a concave peripheral surface (7); drive means (20) for rotating (R) the drum element at such a speed that a flexible image plate (1) located inside the drum element against the peripheral surface substantially retains the shape thereof; a light source (14) for focusing a stimulating light on the image plate (1), a light detector (17) for detecting the emitted light, as well as means (27) for moving the stimulating light and the light detector relative to the image plate in a direction (M) of said axis. The accessories comprise at least two balancing blocks (4, 5), which constitute permanent parts of the drum element and are located at a distance from the axis of rotation. The drum element can be balanced, as it is provided with image plates of varying sizes to be read, by shifting at least one balancing block (5) along a circumference (C) of the drum element to a position corresponding to the image plate.

Abstract:
An imaging module mounting apparatus is provided to improve dynamic performance without creating an overconstraint condition causing misalignment of the imaging module (30). Three solid mounts (170,172,174) are used to establish and maintain critical location datums of the imaging module (30). A single or plurality of variably flexible mounts (180) are used, depending on the size of the module (30), to maintain alignment while minimizing any overconstraint condition caused by the imaging module (30) being distorted out of plane due to thermal distortion and/or static distortion of the mounting frame (40) due to movement of the machine. The variably flexible mount (180) is filled with a high-viscosity silicon polymer. Due to the high-viscosity of the medium, the mount (180) does not respond to fast or high-frequency vibration and appears to be a rigid mount with regard to such movement. The mount will react to very low frequency or static distortion such as that caused by movement of the machine and/or thermal distortion and maintain the imaging module (30) in the proper position to prevent perceptible image defects.

Abstract:
A laser imaging apparatus, such as a laser scanner or laser printer, includes a gas or diode laser (12) which produces a laser beam (18) and an optical system for directing the laser beam onto an object to be scanned or printed. The laser beam (18) is encompassed in a sealed housing (48, 50, 52) from the laser's output to a point at which the beam (18) is no longer subjected to turbulent environment in order to eliminate laser beam pointing instabilities resulting from a turbulent environment caused by thermal sources, cooling fans, and so forth.
Abstract:
An image recording apparatus having a beam scanning optical system (3) using a deflector (300) having a deflecting member (310), wherein a resilient member (1) is interposed between the optical system (3) including said deflector (300) and an image forming portion (2). The resilient member (1) is made of a viscous resilient elastomer of low hardness.
Abstract:
Methods and systems are disclosed for damping unwanted vibrations or ringing of a lens in an imaging device. For example, one method includes determining a target distance to move a lens, and dividing the target distance into multiple steps having at least a first step and a subsequent step, moving the lens, via an actuator, by the first step, thereby causing a first vibration, retrieving a damping parameter indicative of a time delay, the damping parameter being based on at least one characteristic of the actuator and the number of steps, and repeating said moving the lens at least one subsequent step after delaying the subsequent step by one of the damping parameters, each moving the lens a subsequent step causing a subsequent vibration, and the damping parameters affecting the vibration such that the first and subsequent vibrations at least in part modify each other to lower overall vibration.
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.
