Abstract

A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read; a first actuator manually displaceable from a first position to a second position for producing a first light beam for aiming or positioning the reader, and a second actuator manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol. The actuators are independently operative of each other. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol. A graphical user interface simplifies system control functions.

Claims

1. A reader for electro-optically reading indicia such as coded symbols, comprising:

a scanner for generating a scanning beam directed toward a symbol to be read;

a first actuator operatively connected to the scanner and manually displaceable from a first position to a second position for producing a first light beam for aiming the reader at the symbol, and a second actuator operatively connected to the scanner, independently operative from the first actuator, and manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol, said first and second actuators being spaced apart from each other; and

a detector for receiving reflected light from the symbol to produce electrical signals corresponding to data represented by the symbol.

2. A reader as defined in claim 1, wherein said first actuator is a trigger switch displaceable to a third position for changing the first light beam to a second light beam pattern.

3. A reader as defined in claim 1, wherein said second actuator is a trigger switch displaceable to a third position for transferring the data represented by said electrical signals produced by the detector to a peripheral unit.

4. A reader as defined in claim 1, wherein the reader includes a portable, hand-held housing, and wherein the first and second actuators are trigger switches disposed on a handle portion of the housing.

5. A reader as defined in claim 4, wherein said first trigger switch is manually actuatable by the user'"'"'s index finger, and wherein said second trigger switch is manually actuatable by a different finger of the user.

10. A reader according to claim 1;

and further comprising a solar light collector for providing power to said reader.

11. A reader according to claim 1;

and further comprising control means for controlling the scanner, and for processing the electrical signals, including a graphical user interface display on the scanner and a movable positioning element accessible to a user, said control means including means for displaying icons and an indicating cursor on the display, said cursor being movable over the display as the positioning element is moved by the user to a selected one of the icons, said control means being operative for executing a function associated with the selected icon.

12. A reader according to claim 11, wherein the scanner includes a handle which extends along an axis about which the user'"'"'s fingers are curled, and wherein the positioning element is within reach of the user'"'"'s thumb.

13. A reader according to claim 12, wherein the scanner has a top wall, and where the positioning element is mounted on the top wall for revolving movement about the axis.

6. A system for electro-optically reading coded symbols, comprising:

a light source for generating a beam directed toward a symbol to be read;

a detector for receiving reflected light from the symbol to produce electrical signals corresponding to data represented by the symbol; and

a first actuator operatively connected to the scanner and manually displaceable from an off position to a first selectable position for initiating reading of a symbol, and a second actuator operatively connected to the scanner, independently operative from the first actuator, and manually displaceable from a first position to a second position to transfer said data represented by the symbol, said first and second actuators being spaced apart from each other.

7. A system as defined in claim 6 wherein said data is transferred to a printer.

8. A system as defined in claim 6 wherein said data is transferred to a display for visually displaying the data.

9. A reader for electro-optically reading indicia such as coded symbols, comprising:

a light source for generating a light beam directed toward a symbol to be read;

a detector for receiving reflected light from the symbol to produce electrical signals corresponding to data represented by the symbol; and

a first actuator operatively connected to the reader and manually displaceable from an off position to a first selectable position for initiating optical reading of a symbol, and a second actuator operatively connected to the scanner, independently operative from the first actuator, and manually displaceable from a first position to a second position for initiating wireless communication of the data represented by the symbol, said first and second actuators being spaced apart from each other.
