Abstract

A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock. Preferably, the reader is shock protected by a thermo-plastic elastomer housing section. An outgoing light beam is directed at a non-orthogonal angle relative to the PCB.

Claims

1. A hand-held reader for electro-optically reading indicia, comprising:

a) a gun-shaped housing having a hollow, upper body portion extending along a body axis, and a hollow, lower handle portion connected to, and extending along a handle axis downwardly away from, the body portion;

b) a generally planar, printed circuit board mounted in the housing and being the sole printed circuit board within the housing, the sole board having an upper region located within the body portion, and a lower region located within the handle portion, the sole board extending between the upper and lower regions in a direction transversely of the body axis;

c) a light-transmissive window located in the body portion;

d) a scan module mounted at the upper region of the sole board, for scanning light passing through the window; and

e) a coupler mounted at the lower region of the sole board and being in electrical communication with the scan module.

2. The reader of claim 1, wherein the body axis and the handle axis form an obtuse angle.

3. The reader of claim 1, wherein the body portion has a front end region at which the window is located, and a rear end region spaced along the body axis away from the front end region;

and wherein the sole board extends into the rear end region of the body portion.

4. The reader of claim 1, wherein the sole board is perpendicular to the body axis.

5. The reader of claim 1, wherein the window is inclined relative to the body axis.

6. The reader of claim 1, wherein the scan module is operative for directing a light beam through the window to the indicia to be read, for sweeping the light beam across the indicia, for detecting light reflected off the indicia, and for generating an electrical signal corresponding to the indicia from the light detected.

7. The reader of claim 6, further comprising a signal processor on the sole board for processing the electrical signal to obtain data corresponding to the indicia.

8. The reader of claim 7, wherein the coupler is operative for transmitting the data away from the housing.

9. The reader of claim 1, further comprising a battery pack mounted on the sole board for supplying electrical power to the scan module.

10. The reader of claim 1, wherein the coupler is an electrical connector connected to a cable for bidirectional communication with the scan module.

11. The reader of claim 1, wherein the coupler is a wireless transceiver for bidirectional communication with the scan module.

12. The reader of claim 1, further comprising a trigger on the housing for manually initiating reading, the trigger including a trigger switch mounted on the sole board in an intermediate region located between the upper and lower regions of the sole board.

13. The reader of claim 1, wherein the scan module and the coupler are surface-mounted on the sole board.

14. The reader of claim 1, wherein the handle portion has front and rear walls spaced apart along the longitudinal direction, and a pair of side walls spaced apart and extending between the front and rear walls along the longitudinal direction;

and wherein the sole board extends between the side walls.

15. The reader of claim 1, wherein the scan module includes a laser for generating a laser beam.
