Abstract:
A method and apparatus for printing an image on a large surface area or walkway provides for imagewise marking of the surface with a color marking solution, to form a visible image on the surface during an image recording mode of a marking engine. The marking engine includes a scanner and the marking engine moves along the surface and operates the scanner to sense a crude image upon the surface and generates data signals representing the crude image or boundaries defined by the crude image scanned. In response to data signals the marking engine is operated to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image.
Abstract:
In a wire-driving system that drives and moves a movable unit along a guide path, a drive drum member is rotatably provided on the movable unit to be rotated around an axis which is perpendicular to a movement direction of the movable unit. An electric drive motor is provided in the movable unit and operationally connected to the drum member to be rotationally driven in either a first rotational direction or a second rotational direction. A wire cable has a first end and a second end, and is partially wound around the drum member such that a first cable section and a second cable section are extended from the drum member. The respective first and second ends of the wire cable are securely attached to two fixed points beside terminal ends of the guide path such that the first and second cable sections of the wire cable are tensionally extended along the guide path. The respective first and second cable sections of the wire cable are wound around and unwound from the drum member during the rotation of the drum member in the first rotational direction by the drive source, and the respective first and second cable sections of the wire cable are unwound from and wound around the drum member during the rotation of the drum member in the second rotational direction by the drive source, resulting in the movement of the movable unit along the guide path.
Abstract:
Two optical modules with reflecting mirrors provide two moving speeds so as to maintain a constant light path between the scanned image and the image sensor. One of the optical modules, the first module, is mounted with two driving wheels. One driving wheel rubs against a stretched belt to move the first module in one direction. The second driving wheel pulls the second optical module toward or away from the first optical module by means of a second belt which is connected to two sides of the second optical module and loops around the second driving wheel. When the two driving wheels rotate in the same direction, the second optical module moves a half as fast as the first optical module. When the two driving wheels rotate in opposite direction, the second optical module moves twice as fast as the first optical module. Thus, two different moving speeds of the modules are achieved.
Abstract:
The present invention provides for an optical scanning apparatus having a scanner body and a self-propelled light bar assembly supported within the scanner body. In one example the scanning apparatus further includes a drive track supported within the scanner body, and the light bar assembly includes a drive wheel in contact with the drive track. This configuration allows the drive wheel to propel the light bar assembly with respect to the scanner body. In a second example the scanner has a scanner body and a magnet-track portion of a linear electric motor fixedly supported within the scanner body. The light bar assembly includes a slider portion of a linear electric motor, and the light bar assembly is supported in the scanner body to place the magnet-track portion in proximity to the slider portion to thereby allow the light bar assembly to be driven along the magnet-track portion.
Abstract:
A self-propelled printing apparatus to perform printing on an object to be printed includes a moving unit that moves the self-propelled printing apparatus on the object to be printed and a printing unit that performs printing on the object to be printed on the basis of print processing data generated based on information of a position to which the self-propelled printing apparatus has been moved by the moving unit.
Abstract:
A reading apparatus comprising a plate on which a transparent original is placed, and a guide unit for setting the transparent original at a predetermined position on the original plate. A light source unit is settable at plural positions in contact with the guide unit for illuminating the transparent original which is urged against the original plate by the light source unit. A portion of the light source unit which is contacted with the transparent original is chamfered (R-worked) not to damage the transparent original. Further, a portion of the light source unit which is contacted with the transparent original is designed to urge the transparent original at an out of an image area of the original.

Abstract:
Systems, apparatuses, and methods for a self-propelled image translation device are described herein. The self-propelled image translation device may include a propulsion module to control propulsion components to autonomously propel the image translation device over an adjacent medium. An input/output module of the self-propelled image translation device may control input/output components to translate an image between the device and an adjacent medium. Other embodiments may be described and claimed.
Abstract:
A scanning apparatus includes a housing with a scan flatbed. A loading glass is installed at the scan flatbed of the housing for loading a to-be-scanned document. A photoelectric sensing device senses the light corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. The flat cable is designed to include a line peak so that the surface friction between the flat cable and the loading glass can be reduced to line friction. The flat cable can also be shifted near the sidewall of the housing and is inclined to the center of the housing so that the friction traces remained on the loading glass is outside the scan flatbed. Thus, the abrasion on the loading glass can be reduced and the quality of the scanning images can be improved.
