Good read indicator for hybrid code reader
View Patent ↗The present invention relates to an image collecting module. The image collection module is provided with a first indicator operable to provide an indication of a valid read of a first portion of a hybrid dataform and a second indicator operable to provide an indication of a valid read of a second portion of the hybrid dataform.
1. An image collection module comprising:
an optical system that directs a first target area image and a second target area image onto a photosensor array; and
a first indicator and a second indicator that respectively indicate whether a valid detection is made of the first target area image and the second target area image.
2. The image collection module of claim 1 , the optical system comprises a reflector that directs the respective first and second target area images to different portions of the photosensor array.
3. The image collection module of claim 1 , the optical system comprises a reflector that moves to direct one of the first and second target area images to the photosensor array prior to directing the respective other of the first and second target area images to the photosensor array.
4. The image collection module of claim 1 , one of the first and second target areas is a one-dimensional portion of a hybrid dataform, and the respective other of the first and second target areas is a two-dimensional portion of a hybrid dataform.
5. The image collection module of claim 1 , at least one of the first and second indicators comprises a photo indicator.
6. The image collection module of claim 5 , the first indicator comprises a first LED and the second indicator comprises a second LED.
7. The image collection module of claim 6 , the first LED comprises at least a first color and the second LED comprises at least a second color.
8. The image collection module of claim 6 , the first LED is configured to emit a first valid signal that indicates a valid detection of the first target area image and a first invalid signal that indicates an invalid detection of the first target area image, and the second LED is configured to emit a second valid signal that indicates a valid detection of the second target area image and a second invalid signal that indicates an invalid detection of the second target area image.
9. The image collection module of claim 8 , the respective signals are selected from at least one of different color signals, pulsation signals and on/off state signals.
10. The image collection module of claim 5 , at least one of the first and second indicators comprises a visual indicator and at least the respective other of the first and second indicators comprises an audible indicator.
11. The image collection module of claim 1 , further comprising an illumination assembly that spreads an output light onto the first and second target areas such that reflected light is detected by the photosensor array.
12. The image collection module of claim 1 , the optical system further comprises a lens system that focuses the first and second target area images onto the photosensor array.
13. A method of reading a hybrid dataform comprising:
detecting a first target area image and a second target area image directed to a photosensor array; and
indicating whether a valid read is made of each of the first target area image and the second target area image by employing a first indicator for the first target area image and a second indicator for the second target area image.
14. The method of claim 13 , the directing comprises directing the respective first target area image and the second target area image to different portions of the photosensor array.
15. The method of claim 13 , the directing comprises directing one of the first and second target area images to the photosensor array prior to directing the respective other of the first and second target area images.
16. The method of claim 13 , the indicating comprises illuminating at least one photo indicator.
17. The method of claim 16 , the indicating comprises illuminating the first photo indicator to indicate detection of the first target area image, and illuminating the second photo indicator to indicate detection of a second target area image.
18. The method of claim 16 , the illuminating the first photo indicator comprises emitting a first valid signal to indicate a valid detection of the first target area image and a first invalid signal to indicate an invalid detection of the first target area image, and the illuminating the second photo indicator comprises emitting a second valid signal to indicate a valid detection of the second target area image and a second invalid signal to indicate an invalid detection of the second target area image.
19. The method of claim 18 , the illuminating the first and second photo indicators comprises emitting respective signals selected from at least one of different color signals, pulsation signals and on/off state signals.
20. An image collection module comprising:
means for detecting a first target area image and a second target area image; and
means for indicating whether a valid read is made of each of the images of the first target area and the second target area by employing a first indicator for the first target area image and a second indicator for the second target area image.
