1. A shutter arrangement for a document handling apparatus, comprising:
- a channel;
a shutter capable of obstructing the channel and pivotable about a pivot axis into or out of the plane of the document; and
,an elongate actuating member extending away from the pivot axis and connected to the shutter so that actuation of the member pivots the shutter so as to define a moving assembly, wherein the mass of said moving assembly is so distributed that the assembly does not exhibit any turning moment about said pivot axis on vibration of the document handling apparatus to which the pivot axis is connected.

- 19. A shutter arrangement comprising a shutter member including a passage through which a document can pass, said passage being alignable with a document transport passage of a document handling apparatus by pivoting the shutter assembly about the pivot axis, said shutter being located within a surround, wherein the surround and the shutter carry mutually interengaging features to prevent a flat document from passing between the shutter and the surround.

22. A shutter arrangement for a document handling apparatus, comprising:
-
a channel; a shutter capable of obstructing the channel and pivotable about a pivot axis into or out of the plane of the document; an encoder disk connected to the shutter to move therewith for identifying at least four uniformly spaced positions of the shutter, wherein two of the positions correspond to the complete opening of the shutter and two others to its complete closure; a processor electrically connected to the encoder which may, in response to the action of the encoder, order the rotation of the shutter; and
,at least one further component arranged to move with the shutter so as to define a moving assembly, wherein the mass of said moving assembly is so distributed that the assembly does not exhibit any turning moment about said pivot axis on vibration of the document handling apparatus to which the pivot axis is connected. - View Dependent Claims (23)
