PCT No. PCT/JP88/00273 Sec. 371 Date Mar. 15, 1989 Sec. 102(e) Date Mar. 15, 1989 PCT Filed Mar. 16, 1988.A two-dimensional image pick-up device using a one-dimensional image pick-up element which is useful as an image reader. Drive coil type linear motors for driving an element moving carriage in the subscanning direction of the one-dimensional image pick-up element are disposed on both sides of the element moving carriage, enabling the deivce to be economically small-sized as a whole.
Abstract:
There is described an imaging device for capturing images of at least portions of moving objects. The system comprises a stationary camera lens (1 1 ) configured for reproducing an image of at least a portion of each moving object (10) in an imaging plane when said object (10) moves across a capturing region (12). The device further comprises at least one image sensor (13; 23; 33; 43; 53) located in the imaging plane for receiving the reproduced image of the at least a portion of the corresponding moving object (10) and converting said image into electronic signals. The at least one image sensor (13; 23; 33; 43; 53) is mounted on a sensor support (14; 24; 34; 44; 54) adapted to be actuated in a manner that the at least one image sensor (13; 23; 33; 43; 53) is moved in the imaging plane relative to the stationary camera lens (1 1 ), and in a manner that the motion of said at least one image sensor (13; 23; 33; 43; 53) is synchronized with the motion of the moving object (10) to be captured. This ensures that there is substantially no relative movement between the reproduced image in the imaging plane and the image sensor (13; 23; 33; 43; 53) when said moving object (10) moves across the capturing region (12). As a result motion blur of the captured image of the at least a portion of each moving object (10) is prevented or significantly reduced.
Abstract:
The invention relates to a mobile device for emitting audio and video signals in addition to digitally processable information and signals. In order to scan a plane document, the whole length of a line of the document is imaged on a sensor. An optical element (14) and/or a deflecting surface (37) arranged inside the housing (2) are received on an optical carrier (9). The device for scanning a plane document is placed, along with a scanning gate (18), above the document. The optical carrier (9) receiving the optical element (14) is arranged in the housing (2) in a moveable manner by means of a linear drive.
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:
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:
Example implementations relate to a scan carriage of a print apparatus. In some examples, a system may include a print carriage to transit across a print zone of the print apparatus and a scan carriage selectably attachable to the print carriage to transit across the print zone of the print apparatus.
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.
