Abstract

A portable data collection device. The device includes an imaging assembly including a two dimensional (2D) photosensor array. The imaging assembly is selectively actuatable with a first trigger for reading a target dataform in the imaging assembly'"'"'s target area and actuatable with a second trigger for capturing a color image of the target object in the target area. The imaging assembly further includes compression circuitry for compressing digital data representative of the target area when the imaging assembly is actuated to capture an image of the target area. The device also includes a viewing assembly to aid an operator in aiming and positioning the device with respect to a target dataform or target object. In one embodiment of the viewing assembly, a liquid crystal display screen is affixed to a pivoting member. When the viewing assembly is actuated an image of the target area is displaced on the display screen. In a second embodiment of the viewing assembly, a manual pivoting member includes an opening. When the pivoting member is positioned a predetermined distance from the operator'"'"'s eye, a view through the opening corresponds to the imaging assembly'"'"'s target area.

Claims

1. A portable data collection device for reading a dataform positioned in a target area, the reader comprising:

a) a housing forming an interior region,

b) an imaging assembly at least partially enclosed in the interior region, for capturing an image of the dataform within a target area of the imaging assembly and providing decoded data representative of the dataform,

c) a user activated actuator at least partially exposed on the exterior of the housing for actuating the imaging assembly to read a dataform, and

d) a viewing assembly including a pivoting member supported by the housing, the pivoting member pivotable between an upright and a folded down position with respect to the housing and including an opening, the opening sized such that when an operator'"'"'s eye is a predetermined distance from the pivoting member and the pivoting member is in the upright position a view through the pivoting member opening substantially corresponds with the target area of the imaging assembly.

2. The portable data collection device of claim 1 further including a targeting arrangement for directing an illumination intensity distribution to aid in aiming the portable data collection device, the targeting arrangement includes a first and a second targeting light emitting diode and a corresponding first and second targeting optics for focusing light from the targeting diodes, the first targeting optics focusing light from the first targeting diode to generate an illumination intensity distribution substantially in a shape of a first thin rectangle within the target area and the second targeting optics focusing light from the second targeting optics in a shape of a second thin rectangle within the target area, the first and second rectangles being substantially perpendicular.

3. The portable data collection device of claim 1 wherein the pivoting member is hingeably connected to said housing such that the pivoting member is pivoted to the upright position for use and pivoted to the folded down position when not in use and in the folded down position is substantially parallel to a portion of the housing overlied by the pivoting member.

4. The portable data collection device of claim 3 wherein the housing includes a recessed portion into which the pivoting member is received when in the folded down position.

5. A portable data collection device for reading a dataform, the device comprising:

a) a housing forming an interior region;

b) an imaging assembly at least partially enclosed in the interior region, for capturing an image of the dataform in a target area of the imaging assembly and providing decoded data representative of the dataform; and

c) a viewing assembly including a member having an opening through which the target area of the imaging assembly is viewable, the opening sized such that when an operator'"'"'s eye is a predetermined distance from the member a view through the opening substantially corresponds with the target area of the imaging assembly.

6. A portable data collection device for reading a dataform, the device comprising:

a) a housing forming an interior region;

b) an imaging assembly at least partially enclosed in the interior region, for capturing an image of the dataform in a target area of the imaging assembly and providing decoded data representative of the dataform;

c) a user activated actuator at least partially exposed on the exterior of the housing for actuating the imaging assembly to read a dataform; and

d) a viewing assembly including a display screen supported by the housing and electrically coupled to the imaging assembly and display driver circuitry to display an image of the target area captured by the imaging assembly, the display screen being supported by a pivoting member which is hingeably connected to the housing and being pivotable between an upright position and a folded down position.

7. The portable data collection device of claim 6 wherein the pivoting member is substantially parallel to a portion of the housing overlied by the display screen.

8. The portable data collection device of claim 7 wherein the display screen is energized to display an image of the target area captured by the imaging assembly when the pivoting member is positioned in the upright position.

9. The portable data collection device of claim 8 wherein the display screen in deenergized when the pivoting member is positioned in the folded down position.

10. The portable data collection device of claim 9 further including a switch for detecting a position of the pivoting member and causing the display screen to be energized when the pivoting member is in the upright position.

11. A portable data collection device for reading a dataform, the device comprising:

a) a housing forming an interior region;

b) an imaging assembly at least partially enclosed in the interior region, for capturing an image of the dataform in a target area of the imaging assembly and providing decoded data representative of the dataform;

c) a user activated actuator at least partially exposed on the exterior of the housing for actuating the imaging assembly to read a dataform; and

d) a viewing assembly including a display screen supported by the housing and electrically coupled to the imaging assembly and display driver circuitry to display an image of the target area captured by the imaging assembly,

e) a targeting arrangement for directing an illumination intensity distribution to aid in aiming the portable data collection device, the targeting arrangement including a first and a second targeting light emitting diode and a corresponding first and second targeting optics for focusing light from the targeting diodes, the first targeting optics focusing light from the first targeting diode to generate an illumination intensity distribution substantially in a shape of a first thin rectangle within the target area and the second targeting optics focusing light from the second targeting optics in a shape of a second thin rectangle within the target area, the first and second rectangles being substantially perpendicular.
