Description
Technical field
The utility model relates to a kind of electronic bar code scanister, relates in particular to a kind of electronic bar code scanister that scans the shown one dimension of LCD, two-dimensional bar code.
Background technology
Development and extension as the bar code automatic identification technology, having occurred the electronic bar code that shown by display device such as LCD in the prior art, is the application system of the relevant electronic bar code put down in writing of 01100508 Taiwan patent and corresponding mobile phone products etc. as the patent No..This electronic bar code not only its carrier changes, and its characteristic also because the increasing information content, improve data security and become two dimension by one dimension.Along with the change of bar code carrier and bar code self-characteristic, traditional laser bar code scanning device can not adapt to the needs of electronic bar code scanning, and people have developed special scanister at the electronic bar code characteristics thereupon.This electronic bar code scanister adopts common planar scanning of image mode to scan, radiation source becomes two-dimensional array to constitute by photodiode cloth, as the reflected light receiving trap, the CCD element is transferred to signal processing apparatus with signal again and handles with CCD (charge-coupled image sensor) element.Though above-mentioned electronic bar code scanister proposes at one dimension, two-dimentional electronic bar code,, and the application and the development of electronic bar code have been limited thus because that its radiation source is provided with is unreasonable, thereby exists defectives such as irradiates light lack of homogeneity, bar code read false rate height.
The content of utility model
Problem at the prior art existence, the purpose of this utility model provides a kind of novel electron bar code scanner, this device is by improving irradiation configured light sources mode, thereby overcome defectives such as bar code read false rate that existing electronic bar code scanister exists arrives.
For realizing the purpose of this utility model, this electronic bar code scanister comprises a housing, have the one scan window on the housing, the display screen of window size and regular handset is complementary, the reflected light receiving trap is positioned at a side under the scanning window, and apart from the suitable distance of scanning window, be provided with a tilted-putted light guide plate under the scanning window, its size adapts with the size of scanning window, the upper edge is near scanning window, the housing of light guide plate upper edge and scanning window one side fixes, its position, lower edge is corresponding with the position of described reflected light receiving trap, the receiving plane of reflected light receiving trap is positioned at the top of light guide plate upper surface, the corresponding row's pointolite that is provided with light guide plate lower edge end face, be provided with the light reflection horizon on light guide plate lower surface and other three end faces except that the end face of lower edge, the light guide plate upper surface is the light output face.
Further, described pointolite is a light emitting diode, and the pointolite row opposite side relative with described light guide plate lower edge end face is provided with reflex housing.
Further, the shell inner surface of described light guide plate periphery is provided with reflective surface.
Further, one deck anti-reflection film that has on glass at described scanning window place.
Further, uniform in order to the v-depression that penetrates of surface from it of the light in the light guide plate on the described light guide plate lower surface, this v-depression can only be the groove of unidirectional extension, also can be the groove of the mutual right-angled intersection of two-way extension, and light guide plate upper surface top also is provided with diffusion sheet.
After the area source that the utility model electronic bar code scanister constitutes former cause pointolite face battle array becomes the area source that is made of light guide plate, make the intensity of illumination of light source each point more even, eliminated the defective of pointolite each point uneven illumination, overcome the problem of phase mutual interference between each pointolite simultaneously, thereby improved light conditions on the electronic bar code carrier, for improving the scanning accuracy of electronic bar code, reduce the electronic bar code read false rate and created condition.

Embodiment
As shown in drawings, housing 1 upper surface is provided with scanning window 2, glass 3 and 1 bonding connection of housing, and glass 2 surface coverage have one deck anti-reflection film 4.Light guide plate 6 is obliquely installed under scanning window 2, and light guide plate 6 upper edges are fixed on the housing 1 of scanning window 2 one sides, and its lower edge is corresponding with the position of reflected light receiving trap 5, and light guide plate 6 tops also are provided with a diffuser plate 7 simultaneously.Reflected light receiving trap 5 is positioned at a side under the scanning window 2, and apart from scanning window 2 suitable distances.Relative with light guide plate 6 lower edge end faces, be provided with the pointolite 9 that a row is made of light emitting diode, being complementary with pointolite row is provided with a reflection shield 10.Housing 1 inside surface is provided with reflective surface 8.The uniform v-depression 11 of light guide plate 6 lower surfaces, v-depression 11 right-angled intersections distribute, and its surface coverage has one deck reflective membrane 12, and light guide plate about 6 and upper edge end face are coated with one deck reflective membrane 12 equally.
During work, the light that light emitting diode 9 rows send is direct or inject light guide plate 6 from light guide plate 6 lower edge end faces under the reflex of reflex housing 9, when light transmits in light guide plate, continuous reflection through groove 11 place's reflectance coatings 12, penetrate and further all shining on the scanning window 2 electronic bar code display screens behind the light action from the front of light guide plate 6 by diffuser plate 7, receive from the light of the electronic bar code display screen reflected back optical pickup apparatus 5 that is reflected, and pass to the signal processing apparatus (not shown) after converting electronic signal to.
The light that is sent by pointolite 9 is converted to area source by light guide plate 6, and the light that sends from the light guide plate upper surface is by the further equal light of diffusion sheet 7, thereby makes that the light of each point is more even on the electronic bar code display screen that shines scanning window 2 places.Light guide plate 6 area source as a whole simultaneously, the directivity of the light that its upper surface sends also reaches unanimity more, has further reduced light that light source sends to the interference from the light of electronic bar code display screen reflected back.In addition, after the size that the size of scanning window is arranged to be complementary with the electronic bar code display screen,, outside extraneous light is blocked in, reduced the interference of extraneous veiling glare by the electronic bar code display screen that is attached on the scanning window 2.Therefore, the light that reflected light receiving trap 5 is received almost all is the uniform light of electronic bar code display screen reflected back, thereby has guaranteed the scanning accuracy of electronic bar code.
After housing 1 inside surface was provided with reflectance coating 8, the light that pointolite 9 is sent was fully used.By adjusting the luminous intensity of each pointolite 9, or the quantity of luminous pointolite, can adjust the intensity of the light that light guide plate 6 upper surfaces send.
