Abstract: An apparatus for assembling components of a color optical scanner subassembly which includes a first filter member, a second filter member and a photosensor unit. The apparatus includes an imaging means for impinging an imaging light beam from a line object onto the first and second filter assemblies for producing spatially separated color component images of the line object on the photosensor unit. The apparatus also includes a physical adjustment assembly for holding and selectively adjusting the relative position of the first filter member, the second filter member and the photosensor unit in response to data signals generated by the photosensor unit. This positioning accurately locates the filter members relative to the photosensor unit for optimizing performance of the color optical scanner.

Abstract: An aperture and light source assembly including an elongate aperture plate having a longitudinally extending, aperture defining slit at a top end thereof and a light source for illuminating an object to be scanned including a first elongate bulb and a second elongate bulb positioned adjacent opposite lateral sides of the vertically disposed portion of said aperture plate and below the top end slit therein; a connector and spacer assembly fixedly connecting the bulbs in spaced apart, parallel relationship; and an attachment assembly associated with the connector assembly removably attaching the light source to the optical scanner; and whereby the first and second bulbs are installable and removable from the optical scanner as a modular unit.
