Abstract

A hand-held symbology reader having a handle for grasping by a user and a head attached to the handle for adjustable angular movement of the head relative to the handle between the plurality of angular orientations. The head is selectively retained in a selected one of a plurality of angular orientations. The head is rotatable about three axes of rotation relative to the handle. The reader head has a rectangular pixel array that defines a rectangular imaging area, with the pixel array having a first position with a horizontal dimension of the pixel array that is greater than the vertical dimension of the pixel array, and a second position with the horizontal dimension that is less than the vertical dimension of the pixel array. The reader head is moveable such that the pixel array can be rotated between the first and second positions by rotating the reader head relative to the handle while the handle remains in a fixed position.

Claims

2. The hand-held symbology reader of claim 1 wherein said reader head is rotatable relative to said handle through 180 degrees about a first of said two axes of rotation.

3. The hand-held symbology reader of claim 1, further comprising indicia coupled to said reader head indicating to the user the angular orientation of said reader head relative to said handle.

4. The hand-held symbology reader of claim 1, further comprising an adjustment device attached to said reader head that adjusts the angular orientation of said reader head relative to said handle to a selected one of said plurality of angular orientations.

5. The hand-held symbology reader of claim 4 wherein said adjustment device is manually adjustable.

6. The hand-held symbology reader of claim 1, further comprising a trigger for activating said reader head, said trigger being mounted to said handle.

7. The hand-held symbology reader of claim 1, further comprising a stop coupled to said reader head to limit angular movement of said reader head relative to said handle.

8. A hand-held symbology reader, comprising:

a handle for grasping by user;

a symbology reader head rotatably attached to said handle, said reader head being adjustable relative to said handle between a plurality of angular orientations, said reader head including a rectangular pixel array that defines a rectangular imaging area having a long side, said pixel array rotating with said reader head when said reader head is rotated with respect to said handle between a first position with said long side horizontally oriented, and a second position with said long side vertically oriented.

9. A hand-held symbology reader, comprising:

a handle for grasping by a user;

a symbology reader head attached to said handle;

a reading module positioned within said reader head and rotatably supported by said reader head, said reading module being rotatable relative to said handle and relative to said reader head between a plurality of angular orientations; and

a retainer selectively retaining said reading module in a selected one of said plurality of angular orientations.

10. The hand-held symbology reader of claim 9 wherein said reader head is rotatably supported by said handle, said reader head being adjustable relative to said handle between a plurality of angular orientations.

11. The hand-held symbology reader of claim 9, further comprising a power supply attached to said reading module by a flexible interconnect, said flexible interconnect allowing said reading module to move relative to said handle while maintaining said connection to said power supply.

12. The hand-held symbology reader of claim 9 wherein said reading module is rotatable about one axis of rotation relative to said handle.

13. The hand-held symbology reader of claim 9 wherein said reading module is rotatably attached to said handle and includes a rectangular pixel array that defines a rectangular imaging area having a long side, said pixel array rotating with said reading module when said reading module is rotated with respect to said handle between a first position with said long side horizontally oriented, and a second position with said long side vertically oriented.

14. The hand-held symbology reader of claim 9, further comprising indicia coupled to said reading module indicating to a user the angular orientation of said reading module relative to said handle.

15. The hand-held symbology reader of claim 9, further comprising an adjustment device attached to said reading module that adjusts the angular orientation of said reading module relative to said handle to a selected one of said plurality of angular orientations.

16. The hand-held symbology reader of claim 15 wherein said adjustment device is manually adjustable.

17. The hand-held symbology reader of claim 9, further comprising a stop coupled to said reading module to limit angular movement of said reading module relative to said handle.

18. A method of reading symbology with a hand-held symbology reader having a handle and a symbology reader head movably attached to the handle for adjustable angular movement relative to the handle, the symbology having a known angular orientation relative to the handle, comprising the steps of:

positioning the hand-held symbology reader adjacent to the symbology;

holding the handle at a fixed angular orientation relative to the symbology;

moving the symbology reader head relative to the handle about a first axis of rotation from a first position to a second position to point the reader head at the symbology;

moving the reader head relative to the handle about a second axis of rotation to adjust the angular orientation of the symbology reader head to correspond to the angular orientation of the symbology; and

reading the symbology with the symbology reader.

19. The method of reading symbology of claim 18, further comprising the step of releasably retaining the symbology reader head in said second position.

20. The method of reading symbology of claim 18 wherein the symbology reader head rotatably supports a reading module, the reading module being rotatable relative to the handle between a plurality of angular orientations, and the step of moving the symbology reader head about said second axis of rotation includes rotating the reading module relative to the handle to align the angular orientation of the reading module with the angular orientation of the symbology.

21. A hand-held symbology reader, comprising:

a handle for grasping by a user; and

a symbology reader head movably attached to said handle, said reader head being adjustable relative to said handle between a plurality of angular orientations, said reader head being rotatably attached to said handle, said reader head including a reading module that defines an imaging area having a long side, said reading module rotating with said reader head when said reader head is rotated with respect to said handle between a first position with said long side horizontally oriented, and a second position with said long side vertically oriented.

22. The hand-held symbology reader of claim 21 wherein said reader head is rotatable about two axes of rotation.

23. The hand-held symbology reader of claim 21, further comprising indicia coupled to said reader head indicating to the user the angular orientation of said reading module relative to said handle.

24. The hand-held symbology reader of claim 21, further comprising an adjustment device attached to said reader head that adjusts the angular orientation of said reading module relative to said handle to a selected one of said plurality of angular orientations.
