Clamp assembly for detachably clamping spring in electro-optical system for reading indicia

In a scanner for electro-optically reading coded indicia having parts of different light reflectivity by directing light in an outgoing path toward the indicia and by collecting reflected light returning in a return path from the indicia, an arrangement for scanning the indicia, comprising:

• a) a scanning component mounted in at least one of the paths;
• b) a holder for mounting the scanning component for oscillating movement, including a spring having opposite spring end portions between which the scanning component is mounted;
• and
• c) at least one clamp for detachably clamping at least one of the spring end portions on the holder, said one clamp having a fixed clamping portion on the holder, a detachable clamping portion movable from a clamped position in which said one spring end portion is sandwiched between the detachable clamping portion and the fixed clamping portion during scanning, and a detached position in which said one spring end portion is free to be removed from the clamped position, and a flexible fastener for engaging and urging both clamping portions toward each other in the clamped position.
