Abstract
The utility model relates to an automatic bar-code card scanner for reading bar-code cards, being an improvement on the existing drawing groove type scanners. The utility model is mainly characterized in that one end of the scanner is provided with a card positioning groove; an even illuminating light source and a lens are arranged at the side of the card positioning groove; the other side of the lens is correspondingly provided with a wire array CCD chip. In the utility model, the bar-code cards are put into the card positioning groove for automatic scanning without drawing and moving the bar-code cards. As a result, the utility model has the advantages that use is convenient, and the cards are not easily damaged. The utility model can be used for bank auditing, employee's attendance checking, library management, etc. in various departments which have occasions that the bar-code cards are used.
Description
The utility model relates to a kind of bar code card autoscanner that is used for reading the bar code card, is the improvement to existing bar code card scanner.
The card (being called for short the bar code card) that is printed on bar code has been widely used in each departments such as bank audit, staff attendance, library management, paddle-tumble formula scanner is the scanner that is used for reading at present the bar code card specially, in actual use, this scanner exists following deficiency: one, when scanning was read, the operator need hold with the at the uniform velocity mobile scanning groove that streaks of certain speed, otherwise, bar code can not accurately be read in, thus use inadequately convenient; The second, the bar code card often and the cell wall friction be easy to impairedly, this equally also can influence the accurate reading of scanner to bar code.On the other hand, with regard to the scanning reading technique of bar code, occurred a kind of line array CCD chip circuit at present, it need not bar code and moves scanning and the reading that just can automatically finish bar code.
Task of the present utility model is to avoid above-mentioned weak point and bar code card autoscanner that a kind of difficult wound card easy to use is provided.
Task of the present utility model is realized by following scheme: the end at scanner is provided with card locating slot 4, and card locating slot side is equipped with equal irradiation source 6 and camera lens 3, is provided with line array CCD chip 1 in the opposite side correspondence of camera lens.
The course of work of such scheme is as follows: when bar code card 5 is put into card locating slot 4, bar code on the card is illuminated by equal irradiation source 6, and its image is presented on the receive window of line array CCD chip by camera lens 3, line array CCD chip 1 converts corresponding electric signal to and is defeated by its auxiliary circuit with the light intensity signal that is about to bar code symbol, and the standard signal that its scanning can be read is exported to the code translator processing after treatment.According to above-mentioned analysis, the utility model need not to draw and moves the bar code card and just can scan automatically as long as the bar code card is put into the card locating slot, thereby, not only use very easy, and the damage of bar code card can avoid stamping the card the time, the effective life cycle that helps to keep and prolong the bar code card.
Fig. 1 is the structural diagrams of an embodiment of the utility model.
Fig. 2 is the three-dimensional icon of an embodiment of the utility model card locating slot.
Embodiment of the present utility model such as Fig. 1, shown in 2, front end at scanner has the card locating slot 4 that can make bar code card 5 conveniently put into and locate, card locating slot 4 can be the plug-in types of five bread around the top opening, as shown in Figure 2, it also can be the open type of only establishing three baffle plates, downside at card locating slot 4 is provided with equal irradiation source 6, side at the card locating slot also is equipped with camera lens 3, correspondence is provided with line array CCD chip 1 behind camera lens, the image of bar code is injected on the receive window of line array CCD chip by camera lens, between camera lens 3 and line array CCD chip, also be provided with diaphragm 2, the line array CCD chip is connected with its auxiliary circuit, auxiliary circuit comprises the driving circuit of line array CCD chip and accepts the amplification and rectification circuit of its signal, in addition, according to the structural change in the scanner, can in scanner, set up reflective mirror change camera lens 3 line array CCD chip 1 the position is set.Common and the code translator configuration use of the utility model.
Claims (3)
1, a kind of bar code card autoscanner that is used for reading the bar code card, it is characterized in that being provided with card locating slot (4) at an end of scanner, card locating slot side is equipped with equal irradiation source (6) and camera lens (3), is provided with line array CCD chip (1) in the opposite side correspondence of camera lens.
2, by the described bar code card autoscanner of claim 1, it is characterized in that between camera lens and line array CCD chip, also being provided with diaphragm (2).
