Abstract

A scanning head includes a keyboard and a display respectively mounted at rear and front regions of the head. An outgoing laser beam exits a window positioned between the keyboard and the display, and travels over the display. A transceiver and a printer are also mounted on the head.

Claims

1. In a scanning system for reading indicia having parts of different light reflectivity, a scanning head comprising:

(a) a housing having an elongated body portion including a front region, a rear region, and an intermediate body region extending between the front and rear regions;

(b) indicia-detection means for generating a light beam directed along a light path toward indicia to be read, and for receiving reflected light from the indicia to produce electrical signals representative of the indicia;

(c) a keyboard disposed on the rear region of the housing out of the light path for enabling manual data entry without manually blocking the light beam;

(d) a display disposed on the front region of the housing for displaying information;

(e) window means mounted on the intermediate body region of the housing between the keyboard and the display, said window means being light-transmissive and configured and positioned in the light path of the light beam to permit the light beam to pass through and window means and unobstructedly travel exteriorly of and past the front region of the housing over the display; and

(f) read-control means for actuating the indicia-detection means to initiate reading of an indicium.

2. The head as recited in claim 1;

and further comprising a handle connected to the housing for enabling an operator to hold the housing during reading.

3. The head as recited in claim 2, wherein the rear region has an inclined wall on which the keyboard is mounted to lie within ready access of the operator.

4. The head as recited in claim 3, wherein the inclined wall rises in elevation as considered in a direction from the rear towards the front region of the housing.

5. The head as recited in claim 1, wherein the keyboard has multiple keys.

6. The head as recited in claim 2, wherein the front region has a generally planar wall on which the display is mounted to lie along a direct line-of-sight of the operator.

7. The head as recited in claim 1, wherein the display includes a screen having a predetermined area.

8. The head as recited in claim 2, wherein the window means includes a window mounted on a sloped wall that falls in elevation as considered in a direction from the rear towards the front region of the housing.

9. The head as recited in claim 1, wherein the housing has side walls spaced transversely apart of each other by a predetermined width, and wherein the exterior transmission of the light beam is independent of the predetermined width of the housing.

10. The head as recited in claim 1, wherein the indicia-detection means includes a laser source for generating an incident laser beam, sensor means for detecting the variable intensity of laser light reflected from the indicium over a field of view, and scanning means for scanning at least one of said incident laser beam and said field of view.

11. The head as recited in claim 1;

and further comprising transceiver means in the housing, for transmitting the electrical signals to a remote site, and for receiving return electrical signals from the remote site.

12. The head as recited in claim 2, wherein the read-control means includes a manually actuatable trigger switch mounted on the handle.

13. The head as recited in claim 1;

and further comprising printer means in the housing, for printing data.

14. In a scanning system for reading indicia having parts of different light reflectivity, a scanning head comprising:

(a) a generally gun-shaped housing having an elongated body portion including a front region, a rear region, and an intermediate body region extending between the front and rear regions, and a handle portion connected to the body portion to enable an operator to hold the housing and aim the body portion at the indicia located at a distance from the front region of the housing;

(b) indicia-detection means for generating a light beam directed along a light path toward indicia to be read, and for receiving reflected light from the indicia to produce electrical signals representative of the indicia;

(c) a keyboard disposed on the rear region of the housing out of the light path, for enabling the operator to manually enter data without manually blocking the light beam, said keyboard being located within ready reach of the operator;

(d) a display disposed on the front region of the housing, for displaying information, said display being located within ready viewing by the operator during indicia reading;

(e) window means mounted on the intermediate body region of the housing between the keyboard and the display, said window means being light-transmissive and configured and positioned in the light path of the light beam to permit the light beam to pass through the window means and unobstructedly travel exteriorly of and past the front region of the housing over the display; and

(f) read-control means for actuating the indicia-detection means to initiate reading of an indicium.

15. The head as recited in claim 14, wherein the housing has a top wall having a front section, a rear section and an intermediate section;

and wherein the display, the keyboard and the window means are all mounted on the top wall at said front, rear and intermediate sections, respectively.

16. The head as recited in claim 15, wherein the rear section rises in elevation as considered in a direction from the rear toward the front region of the housing, and wherein the intermediate section falls in elevation as considered in the direction from the rear toward the front region of the housing, and wherein the front section has a generally constant elevation.

17. The head as recited in claim 14, wherein the keyboard has a plurality of manually depressable keys all mounted rearwardly of the window means to enable key depression even during reading without manually blocking the light beam.

18. The head as recited in claim 14, wherein the indicia-detection means includes a laser light source for generating a laser light beam.
