摘要： A calibration system (100) for an imaging apparatus (110) is disclosed. The calibration system (100) determines the image (218) distance between a lens (134) and a photosensor (150) located in the imaging apparatus (110). Calibration involves generating an image of a calibration target (250) where the calibration target (250) has a predetermined length (256) and is located a predetermined distance (224) from the photosensor (150) in the imaging apparatus (110). The imaging apparatus (110) may then measure the length (162) of the image of the calibration target (250) on the photosensor (150). Based on the length (162) of the image of the calibration target (250) on the photosensor (150), the calibration system (100) may calculate the image distance (218). Said imaging apparatus in the form of a bar code reader may be used in an automated media exchanger.

摘要： In a lens focusing and holding arrangement for an imaging system (60) including a photosensor array (510), the lens (570) is in contact with a reference surface or surfaces (274, 276) formed within the imaging system housing (200) and is translatable along the surface (274, 276) in directions toward and away from the photosensor array (510) in order to adjust the focus of the imaging system (60). A lens retention clip (600) is provided to secure the lens (570) within the imaging system housing (200) and to cause translational movement of the lens (570) along the imaging system reference surface (274, 276). When focusing the imaging system (60), the lens retention clip (600) is in a first operating condition in which the lens retention clip (600) applies a relatively small force tending to hold the lens (570) in contact with the housing reference surface (274, 276). After the desired focus has been set, the lens retention clip (600) is placed in a second operating condition in which the lens retention clip (600) applies a relatively high force tending to hold the lens (570) in contact with the housing reference surface (274, 276), thus locking the lens (570) in place.

摘要： An illuminating device (320) comprises a light source (400) associated with a lens (510) having an integrally formed reference surface (580) to which the light source (400) is attached. The light source (400) is a linear array (432) of surface mount light-emitting diodes (430) that emit light in a direction parallel to the surface (424) to which they are mounted. The precise location of the light source (400) relative to the lens (510) concentrates the light emitted from the light source (400) onto the object which is to be illuminated, thus reducing the intensity of light required and the power requirement of the light source (400).

摘要： An improved optical assembly for acquiring an image of an object (300) is disclosed. The optical assembly (200) comprises an illuminator (260) used to illuminate the object (300) and an imaging device (280) used to generate an image of the object (300). The illuminator (260) has a light source (240) associated with an illuminating lens (262) wherein the illuminating lens (262) has an optical axis (278). A light beam (201) is generated by the light source (240) and passes through the illuminating lens (262) to illuminate the object (300). The imaging device (280) has a photosensor (284) associated with an imaging lens (282) wherein the imaging lens (282) has an optical axis (296). An image beam (288, 291) of light reflects from the object (300) and is focused by the imaging lens (282) onto the photosensor (284). The light beams associated with the illuminator (260) and the imaging device (280) are steered to intersect at a common point on the object (300). Steering the light beam (201) is accomplished by spacing the light source (240) a distance (232) from the optical axis (278) of the illuminating lens (262). Steering the image beam (288, 291) is accomplished by spacing the photosensor (284) a distance (234) from the optical axis (296) of the imaging lens (282).

摘要： A bar code reading system (10) comprises a first bar code label (14) and a second bar code label (16). The first bar code label (14) is positioned on an object (18) at a first location (20) and in a first orientation (22). The second bar code label (16) is positioned on the object (18) at a second location (26) and in a second orientation (28). The first and second bar code labels (14, 16) each have indicia (24, 30) thereon representative of a label data set. Bar code reading apparatus (32) positionable next to the object (18) has a limited field of view (90) such that the bar code reading apparatus (32) reads only first and second portions (34, 36) of the first and second bar code labels (14, 16). The bar code reading apparatus (32) produces first and second data sets representative of the first and second portions (34, 36). A data processing system (96) operatively associated with the bar code reading apparatus (32) combines the first and second data sets to produce a combined data set representative of the label data set.
