Abstract
The invention relates to liquid crystal safety card swiping equipment, which comprises a PCB (printed circuit board), a card swiping device and liquid crystals, wherein a pot sheet which is positioned under the liquid crystals and covers a switch is arranged on the PCB, the liquid crystals are arranged on the PCB through a liquid crystal support frame, a thin sheet extends out from the liquid crystal support frame in a position under the liquid crystals, an elastic element downwards pressing the pot sheet is arranged on the liquid crystal support frame, and the elastic element simultaneously and upwards props up the thin sheet so that the highest point of the thin sheet after the upward deformation approaches to the edges of the liquid crystals. The maximum stress points of the liquid crystals are positioned on the edges, and meanwhile, small parts are averagely dispersed to the middle, so black spots due to liquid crystal deformation cannot be caused, and the appearance scheme exertion is ensured. When the liquid crystals receive safety attack, the safety triggering can be caused once the liquid crystals are turned up even when an external lens is turned open, and higher safety and high reliability are realized.
Description
Technical field
The present invention relates to a kind of swiping card equipment of liquid crystal safety.
Background technology
At present, the mode that the safeguard construction of liquid crystal display adopts eyeglass in-built often, or the windowed regions of display is done little, do not allow liquid crystal display can dig easily; When directly installing switch under liquid crystal, because liquid crystal directly pushes down switch, therefore the liquid crystal back side also can pressurized and produce blackspot, has had a strong impact on outward appearance.
The deck of present use mainly contains two kinds of forms: one is monoblock type, includes card slot; Another kind is simple type, and card slot need do structure in addition.The major defect of monoblock type deck is that occupied circuit board space is too large, and for portable equipment MPOS, mini pair, IC-card card reader, require miniaturization day by day, it takes up room and has had a strong impact on the stacking of machine, cannot realize the reduction of equipment size.And simple type IC-card seat, can arranging devices in other position of IC-card groove, efficiently utilize not busy complementary space.But there is following defect in existing simple type IC-card holder structure: on the one hand, and structure is still compact not, takies useful area too large; On the other hand, as shown in Figure 4, its contact is all exposed at outer circumferential side, and equipment is easy to be subject to security attack.
In addition, the shell fragment shape of magnetic head and fixed form, play very crucial effect to brush magnetic stripe card success ratio.The shape of magnetic head has influence on the dynamics of brush magnetic stripe card, wants to ensure that magnetic head and card have good laminating degree in the process of brush magnetic stripe card.Special in the small-sized swiping card equipment such as MPOS, IPOS, the shell fragment design of magnetic head and fixed form have higher requirement.
The shell fragment shape of existing magnetic head fails to take into full account the distortion of brush magnetic stripe card process, have impact on feel and the success ratio of brush magnetic stripe card, and flexible fixed form is mainly adopted and is screwed and hot melt pillar simultaneously.Wherein, adopt and be screwed, easily cause the fastened rear distortion of shell fragment, cause that brush magnetic stripe card dynamics consistance is bad, the not high defect of success ratio; Adopt hot melt pillar, brush magnetic stripe card number of times and consistance are all bad.
