Abstract:
PROBLEM TO BE SOLVED: To provide an original reader in which a reading means is moved without contact with contact glass and a conventional harmful effect accompanied by contact movement of the reading means is fundamentally resolved. SOLUTION: The original reader is provided with an original placing stand 2 having contact glass 21 on which an original is placed and a reading means 3 formed of a contact-type image sensor 35 which is stored in a cabinet 1 and reads the original positioned on contact glass 21. The reading means 3 is separated from contact glass 21. The means reads and scans the original in a non-contact state from a home position A to a reading final position B, and the means can be moved to the home position A from the reading final position B.

Abstract:
A device for reading graphic symbols impressed on a sheet, comprising light sources for illuminating the sheet, an optical reading system and an array of photo-electric sensors for generating electrical reading signals. The device is compact in structure and of small dimensions, so as to allow it to be mounted upon the head-carrying carriage of a printing machine or typewriter. The device makes it possible to create, in a particularly simple form, reading apparatus for facsimiles or for optical character recognition (OCR) reading apparatus for memorizing signatures, graphical symbols and drawings or mathematical symbols, or apparatus for copying documents.
Abstract:
This invention involves an automatic document feeder composed of a transparent sliding platform (1), side guides (3), longitudinal guides (7) and a horizontal guide (2), a system of springs (9), a controller (22), a linear actuator (4), a protection bar (12), a rigid part (11), a set of bushings, bearings (20), document detection and motion sensors, (13) and an end position sensor (10), a linear spring (14), a bobbin (5) and a motor (6). The invention can be adapted to all types of document reader (21) and reads flat and bulky documents alike. The invention also includes the operating method of the automatic document feeder.
Abstract:
An automatic self-centering chuck system for use on an engraver. The chuck system includes a plurality of jaws which are slidably mounted for movement in a radial direction toward a central aperture of the chuck to clamp a shaft for an engraving cylinder. Each of the jaws (102) is actuated for movement by a lever (132) pivotally mounted within the chuck. The levers (132) are actuated for pivotal movement by an axially reciprocating drawbar (64) which is energized for movement by a series of pneumatic cylinders. The components of the chuck are accurately machined to provide close tolerance, precise movements of the jaws (102) whereby a cylinder (24) will be accurately positioned at the central rotational axis of the chuck. In order to ensure that the precise level of jaw movement is maintained throughout the life of the chuck, a lubricant flushing or purging system is provided for flushing normal wear particles from the precision components internal to the chuck.
Abstract:
A carriage positioning structure includes a carriage pivoted to a longitudinal guide rod and reciprocated along a longitudinal sliding rail inside a scanner between a bottom shell and a flat glass plate, an image pick-up mechanism carried on the carriage and moved with the carriage to pick up the image of an object placed on the flat glass plate, a bottom guide wheel mounted on the carriage at the bottom and supported on the longitudinal sliding rail to guide reciprocating movement of the carriage along the longitudinal sliding rail, and a top guide wheel mounted on the carriage at the top and spaced below the flat glass plate by a gap, the top guide wheel being forced into contact with the flat glass plate by the gravity weight of the carriage when the scanner is turned upside down, permitting the carriage to be reciprocated on the flat glass plate along the longitudinal guide rod so that the image pick-up mechanism can pick up the image of a 3-D document placed below the scanner.
Abstract:
A method and apparatus for automated loading and unloading of a cylinder (114) in an engraver (110) which permit the engraver (110) to accommodate cylinders (114) of differing geometries, including a range of lengths, diameters, and mounting configurations. The engraver (110) includes a headstock (116) and tailstock (118) which rotatably support a cylinder (114) at an engraving station (115) in the engraver (110), and a cylinder handling system having at least one cylinder (114) and support (130) for supporting the cylinder between the headstock (116) and tailstock (118) during loading and unloading of the cylinder (114). In one form, the cylinder supports (130) each have a telescoping support member having a support nest for engaging and supporting the cylinder (114) at the engraving station (115). In another form, the cylinder supports (130) each have a support housing and support structure mounted to the support housing, the support structure including at least one cylinder receiving area, selection being possible between plural cylinder receiving areas for receiving cylinders (114) of different dimensions.
Abstract:
A method and apparatus for automated loading and unloading of a cylinder (14) in an engraver (10). The method and apparatus permit the engraver (10) to accommodate cylinders (14) of differing geometries, including a range of lengths, diameters and mounting configurations. The engraver (10) comprises a headstock (16) and a tailstock (18) which cooperate to rotatably support a cylinder (14) at an engraving station (15) in the engraver (10). The engraver (10) also comprises a cylinder handling system having at least one cylinder support (30) for supporting the cylinder (14) between the headstock (16) and tailstock (18) during loading and unloading of the cylinder (14). The cylinder handling system comprises a driver (32) for driving the cylinder support (30) towards and away from the engraving station until the headstock (16) and tailstock (18) engage and rotatably support the cylinder (14). Once the cylinder (14) is rotatably supported between the headstock (16) and tailstock (18), then the cylinder support (30) is retracted. Each cylinder support (30) comprises a telescoping support member (34) having a support nest (36) for engaging and supporting the cylinder (14) at the engraving station (15).
Abstract:
A rotatable drum for use in a scanner or plotter, and a mounting mechanism for supporting and turning the drum about an axis. The drum has a cylindrical substrate-mounting surface, and an end of the drum adapted for permitting the releasable attachment of the drum to the scanner's or plotter's supporting and turning means. The drum's substrate-mounting surface and the drum's attachment end are preferably made of the same material, preferably acrylic. The attachment end of the drum includes a disk at the end of the drum. The disk preferably has an opening or openings passing from its outer face to its inner face. The attachment end permits the releasable attachment of the drum to the scanner or plotter by a mounting mechanism. The other end of the drum preferably is not attached directly to the rest of the scanner. The mounting mechanism for releasably attaching the rotatable drum includes a drum mount attached to and rotatable by a motor. In a preferred embodiment, a clasp stem, passing through a drum-mount opening, has a clasp finger rigidly attached thereto. A cam surface, having a varying elevation, can be rotated so as to push the cam stem through the drum-mount opening. A spring urges the stem against the cam surface. As the cam surface is rotated with respect to the drum mount, the distance between the finger and the drum mount's exterior side varies. The finger can pass through the opening in the attachment end of the drum, and the drum may be clasped between the finger and the drum mount's exterior side.
