A support for a linear source of radiation such as a linear LED array is fixed to a support for a linear light focusing means. A flange having a plurality of apertures which flange is fixed with respect to one of the supports receives a pin in each aperture which pin has a small cross-section compared to its respective aperture. A washer around each pin is fixed by adhesive to the flange and restricts movement of the pin laterally relative to the flange. The opening in the washer permits movement of the pin longitudinally which allows for thermal expansion of one support compared to the other.

Assembly containing a linear focusing means and method of making same

A mount maintains a linear assembly, for example an LED printhead assembly, in operative relation to a rotary component whose location and orientation is not always precisely determinable. The mount is particularly useful when the rotary component is routinely removable from the apparatus, for example, if the rotary component is a roller about which is trained a web which must be replaced periodically and upon which the printhead assembly acts. The mount contacts the rotary component restricting movement of the printhead assembly relative to the rotary component about x and y axes generally orthogonal to the primary axis of the rotary component but permits movement of the printhead assembly with the rotary component. The printhead assembly is supported by a mechanism which includes a set of flexure members which in combination both resiliently urge the assembly against the rotary component and also permit its rotation about the x and its y axes and linear movement parallel to all axes while preventing its rotation about the primary axis.

Mount for linear assembly

A linear printhead writer assembly has a rigid box-like support housing which independently supports and protects an LED printhead and a linear lens array. The housing has a front wall to which locating surface means are fixed and which are intended to engage locating bearing surfaces on a printer or similar apparatus.
