Abstract

A device for illuminating a portion of a hand-held scanner to indicate a status of the scanner provides an even distribution of light emission. The device might include various elements that facilitate an even distribution of the light. For instance, in one aspect the device includes a set of reflective surfaces that are positioned throughout the scanner together with light-emitting devices (e.g., LED) in a manner to evenly transmit light emissions. In another aspect, the device includes a light-diffusing translucent member, which smoothly and evenly presents the light emissions that are reflected off of the reflective surfaces.

First claim

The invention claimed is:

1. An illumination system for illuminating a body of a hand-held scanner, the illumination system comprising:
a first reflecting plate that extends from a base and that includes one or more surfaces for reflecting light emitted from one or more light-emitting devices;
a second reflecting plate that extends from the base and that includes one or more surfaces for reflecting light emitted from one or more light-emitting devices; and
a first set of one or more light-emitting devices positioned between the first reflecting plate and the second reflecting plate.

2. The illumination system of claim 1 further comprising, a second set of one or more light-emitting devices positioned underneath the first reflecting plate and a third set of one or more light-emitting devices positioned underneath the second reflecting plate.

3. The illumination system of claim 1 , wherein the one or more surfaces of the first and second reflecting plates include a reflecting coating.

4. The illumination system of claim 1 further comprising, a light-diffusing body that integrates with a shell of the hand-held scanner and that diffuses light reflected from the first and second reflecting plates.

5. A hand-held scanner comprising:
an upper housing member;
a lower housing member that attaches to the upper housing member to enclose a space, wherein the upper housing member and the lower housing member combine to at least partially form a scanner head and a scanner handle;
an underskin positioned in the space and between the upper housing member and the lower housing member, wherein the underskin includes a luminous stripe that extends along a length of the upper housing member and the lower housing member;
a first set of one or more light-emitting devices positioned in the scanner head;
a set of one or more reflective plates positioned in the scanner head to collect and diffuse light from the first set of one or more light-emitting devices, wherein light reflected off of the one or more reflective plates is diffused through the luminous stripe; and
a second set of one or more light-emitting devices positioned in the scanner handle, wherein the lower housing member includes a surface to collect and diffuse light from the second set of one or more light-emitting devices and to the luminous stripe.

6. The hand-held scanner of claim 5 , wherein the upper housing member includes an upper-indicator window and wherein the underskin includes an upper-indicator portion that aligns with the upper-indicator window, the upper-indicator portion being substantially uniformly illuminated by the first set of one or more light-emitting devices reflecting off of the one or more reflective plates.

7. The hand-held scanner of claim 5 , wherein the luminous stripe forms at least part of an external-facing side wall of the hand-held scanner.

8. An underskin for dispersing light in a hand-held scanner, the underskin comprising:
a central portion having a head portion positionable in a scanner head and a handle portion positionable in a scanner handle, the head portion including an upper-indicator portion;
a first side luminous stripe extending along and terminating a first side of the handle portion; and
a second side luminous stripe extending along and terminating a second side of the handle portion, wherein the central portion, the first side luminous stripe, and the second side luminous stripe are constructed of a diffuse material to diffuse light from the central portion to the first and second side luminous stripes.

9. The underskin of claim 8 , wherein the underskin includes a top surface and a bottom surface, and wherein the upper-indicator portion is positioned on the top surface.

10. The underskin of claim 9 , wherein the bottom surface includes one or more strengthening ribs that are also constructed of the diffuse material.

11. The underskin of claim 9 , wherein the central portion includes a curved portion at an interface between the head portion and the handle portion, such that the underskin generally curves away from the bottom surface and curves towards the top surface.

12. The underskin of claim 8 , wherein the diffuse material includes a plastic.

13. The underskin of claim 8 , wherein the diffuse material includes a rubber.
