A connector system substantially rigidly connects a carriage guide rod to a base support structure of a hardcopy apparatus and includes a connector element rigidly fixable to the base support structure. The connector system has a pin which is held in a first bore in the guide rod by a retaining screw in a second bore of the guide rod. The connector system can be adjusted with six degrees of freedom before final fixing. The introduction of a further screw in a threaded part of the first bore permits vertical adjustment of the pin. The connector system can alternatively be used to rigidly secure a printer platen.

To assemble a printer chassis comprising three structural aluminium beams extending between two structural sideplates, the printer carriage beam is first attached to the sideplates by means of attachment points arranged along a straight line and then the printing beam and lower beam are attached to provide a vibration- and deformation-resistant chassis relative to which all the other printer components are referenced. Slider rods are mounted on the printer carriage beam by means of screws which hold the rods against the beam to keep them straight. The screws also pass through apertures in rod supports, the apertures being sized to permit longitudinal thermal movements of the rods relative to the beam.

A device for changing styli or probes in a coordinate measuring machine has a magazine (330) with several stations each holding a stylus or probe (320). A holder (310) on the quill of the coordinate measuring machine has an opening (313A), so that kinematic support elements (325) in the holder (310) can be moved underneath cooperating kinematic support elements (324) on the stylus (320). When the holder (310) is engaged in the magazine (330), an extension plate (334) causes the arm (314) to swing out of the way. This arrangement enables the holder (310) to pick up the stylus (320) purely by translational movements of the holder (310), without the need for any separate motor or electromagnet to couple the stylus to the holder.

An air pressurization system is incorporated as part of a replaceable auxiliary ink supply for an ink jet printer. The auxiliary ink supply cartridge includes a pressurized container having air, ink and electrical signal connections. The air pressure applied to the auxiliary ink supply is monitored to be maintained in a predetermined range in accordance with a start-up sequence, an operational sequence, a waiting time, and a close-down sequence.
摘要:
An ink container for an inkjet printing system is described, including an assembly of a simple housing with caps bearing indicia and protective surfaces to enable effective handling, aligning, keying and latching of the ink container. The ink container includes an ink container housing, the housing including an ink reservoir and a fluid outlet in fluid communication with said reservoir. The fluid outlet is for providing ink to the inkjet printhead. The container further includes a separately fabricated first cap attached to an end of the housing, the first cap having a plurality of mechanical features that provide mechanical functions for the ink container. The end of the housing is a leading end relative to a direction of insertion of the ink container into the printing system. The mechanical functions can include positioning the ink container relative to the supply station, a keying function for preventing installation of an ink container in the supply station without a cap providing the keying function. The mechanical features can include a boss for protecting a leading surface of the ink container and the fluid outlet from physical damage. The trailing end of the housing has attached to it a second cap having a latch feature for latching the ink container in the supply station, and an oversized handle that prevents backwards insertion. The housing includes a pressure vessel that surrounds the ink reservoir, and the first cap is secured to the pressure vessel.
摘要:
A replaceable ink container for providing ink to a printing device. The ink container having leading and trailing edges with respect to an insertion direction for the ink container into the printing device. The ink container includes a fluid outlet disposed on the leading edge and configured for connection to corresponding printing device fluid inlet. The ink container also includes an engagement feature disposed toward the trailing edge and extending outwardly from an ink container outer surface. The engagement feature is configured for insertion into a recessed engagement feature associated with the printing device. With the ink container properly positioned within the printing device and biased in a direction opposite the insertion direction, the engagement feature associated with the ink container engages the recessed engagement feature associated with the printing device. The engagement of the engagement features on each of the ink container and printer maintains the fluid outlet in engagement with the corresponding printing device fluid inlet.
摘要:
A measurement probe for use on machine tools or coordinate measuring machines has a stylus (12) mounted in a probe body (10), for displacement in each of the axes x,y,z. On each axis, the relative motion is supported by a pair of cylindrical linear bearings, which are parallel to each other and spaced apart. The bearings comprise a shaft (30) and concentric sleeve (26), between which is located a cage (28) of ball bearings. The arrangement achieves good performance in a relatively small housing.

A device for changing styli or probes in a coordinate measuring machine has a magazine (330) with several stations each holding a stylus or probe (320). A holder (310) on the quill of the coordinate measuring machine has an opening (313A), so that kinematic support elements (325) in the holder (310) can be moved underneath cooperating kinematic support elements (324) on the stylus (320). The holder (310) is then lifted up to engage the kinematic support elements, and the stylus can then be carried horizontally out of the magazine (30). During this operation, the kinematic support elements are biased into engagement initially by a leaf spring (335), and subsequently by a spring-loaded arm (314) in the holder (310), which bears against the top of a plate (322) of the stylus (320). When the holder (310) is engaged in the magazine (330), an extension plate (334) causes the arm (314) to swing out of the way. This arrangement enables the holder (310 ) to pick up the stylus (320) purely by translational movements of the holder (310), without the need for any separate motor or electromagnet to couple the stylus to the holder.
