Embodiment
By describe in detail technical scheme technology contents, structural feature, realized object and effect, coordinate accompanying drawing to be explained in detail below in conjunction with specific embodiment.
Refer to Fig. 1-5, a kind of key device of the present embodiment, comprise push-button array 1, push-button array is positioned on shell face 140, push-button array can be digital keys array, also can be the push-button array of letter or other implications, key device can be designed to the rectangular structure shell had as Figure 1-3, and now the plane at push-button array place is shell face 140; Key device also can be designed as the shell face 140 only with planar structure and the structure without other shell surfaces.
As Fig. 1, shell face 140 is provided with peristome, shown opening is in the upside of push-button array, and peristome 130 runs through shell face 140; Be provided with reel 110 below shell face 140, reel be wound with film 112, film is for covering push-button array (as shown in Figure 2).
As shown in Figure 2, during use, film 112 is pulled out peristome 130, and overlay keyboard array, make user in use without the need to directly contacting keyboard, and then reduce infection and the diffusion of disease carrying germ or dirt on keyboard.
In a preferred embodiment, reel stand 114, the axis of rolling 116 are set below shell face 140.According to the difference of reel, the axis of rolling can be fixed on drum center axle, also can be through the hollow bulb of reel, makes reel can be that axle rotates with the axis of rolling, and rotate direction R institute as shown in the figure.The two ends of the axis of rolling 116 are arranged on reel stand 114, to limit the range of movement of the axis of rolling 116.The axis of rolling can be pivotally fixed on reel stand, also can be limited in reel stand, as shown in Figure 2, reel stand is a pair N-shaped support, the bottom of key device is fixed in the bottom of n word, is understandable that it also can be fixed on miscellaneous part upper, makes reel stand to limit the axis of rolling; Described reel stand is fixed on below shell face.
Preferred described peristome is strip, and the longer internal diameter of peristome is identical with the rotor shaft direction of reel, and described peristome is used for passing through film.
In a preferred embodiment, as shown in Figure 5, silica gel strip 150 is also provided with in the both sides of digital keys array.In use, covered by film 112 on keyboard and silica gel strip 150, together with film 112 is more closely attached to silica gel strip under the effect of electrostatic and tension force, film 112 covers push-button array and does not move, and is user-friendly to button.
As seen in figs. 5-6, the downside of described digital keys array is provided with silica gel strip 160, and silica gel strip can be arranged on shell face 140, also can be arranged on the downside in shell face 140 as shown in Figure 7.In use, the end of film 112 is attached to silica gel strip 160, makes the tension force between film and silica gel strip and electrostatic make film 112 cover push-button array and does not move, be user-friendly to button.
Preferably all can be provided with silica gel strip in the setting of the downside of digital keys array and both sides.
For the ease of using above-mentioned film, as shown in Figure 4, film arranges the tear fracture line 1123 of rule, and film is divided into identical film block 1121 by tear fracture line 1123, and tear fracture line facilitates user to be torn by the film used at tear fracture line position.Tear fracture line can be the sequence of point-like also can be a wire sequence.
Above-mentioned key device is applied to POS, cash dispenser and ticket taking machine etc. by inventor; replace the button on POS, cash dispenser and ticket taking machine; make POS, cash dispenser and ticket taking machine have above-mentioned key device, the contact of protection user and keyboard, and then be reduced by keyboard disease carrying germ or dirt.
Be understandable that, the push-button array in such scheme replaced to resistive touch screen and is also fine.If the push-button array in such scheme is replaced to capacitive touch screen, corresponding film adopts conducting type film.
