Benefits of technology

"The present invention is a combined colored image projector and bar code reader in a handheld housing. The device can be used as a colored image projector or a bar code reader, and it includes an electro-optical assembly for reading bar code symbols and projecting a bit-mapped colored image. The device also has a mode selector for selecting between the display mode and the reading mode. The assembly includes a plurality of lasers and photodetectors for scanning colored indicia and capturing the colored image. The device also has a processor for decoding the electrical signal and a memory for storing the data. The invention provides a convenient and portable solution for acquiring and storing data from bar code symbols and downloading it to a computer."

Problems solved by technology

Because of the size and optical and electronic complexity of scanning systems and bar code readers, they generally have heretofore not been combined with other devices in the same housing.

Embodiment Construction

[0048] As used in this specification and in the appended claims, the term “indicia” broadly encompasses not only symbol patterns composed of alternating bars and spaces of various widths commonly referred to as bar code symbols, but also one or two dimensional graphic patterns, such as signatures as well as alphanumeric characters. In general, the term “indicia” may apply to any type of pattern or information which may be recognized or identified by scanning a light beam and / or a field of view of a photodetector, and detecting reflected or scattered light as a representation of variations in light reflectivity at various points of the pattern or information. A bar code symbol is one example of an “indicia” which the present invention can scan.

[0049]FIG. 1A illustrates an example of a prior art bar code symbol reader 10 implemented as a gun shaped device, having a pistol-grip type of handle 53. A lightweight plastic housing 55 contains a light source 46, a detector 58, optics 57, si...

Abstract

A portable instrument incorporates an electro-optical assembly for reading indicia during a reading mode, and for projecting a bit-mapped color image during a display mode. A manually operable switch on the instrument is disposed for selecting one of the modes. The color image is formed by pulsing a plurality of differently colored lasers at selected times on selected scan lines.
