摘要:
A scanning device such as a printer (30) has a trapezoidal carriage support beam (32) which permits a compact juxtaposition of the carriage slider rod (33), the printhead (36), a drive belt (71, 72) and an encoder device (50). A second slider mounting for the printer carriage (100) comprises a bushing (150) incorporating a part-spherical portion (65) and an arm (152) which engage with corresponding parts of the carriage.
摘要:
A carriage slider rod (35) is mounted on a steel beam (11) by means of brass support elements (20). The support elements (20) are first riveted to the beam (11) and then have precisely aligned V-shape grooves (30) machined therein to provide accurate location for the slider rod (35). The slider rod (35) is screwed to the beam using central bores (24) passing through the support elements (20). To fix the support elements (20) to the beam, they are first located in respective apertures (19) and then deformed by a clenching tool, one jaw of which passes through an adjacent aperture (18) in the bottom wall of the beam.
