Abstract
The utility model relates to a peep-proofness-enhanced password keyboard peep-proof device with an assistance function, which comprises a password keyboard body, the password keyboard body comprises a keyboard area and a peep-proof baffle, the peep-proof baffle is connected with the front, the left and the right periphery parts of the keyboard area, the front peep-proof baffle is provided with a curved part which can cover the upper side of the keyboard area, and the password keyboard peep-proof device is characterized in that the curved part of the front peep-proof baffle is connected with a lens which covers the keyboard area. The password keyboard peep-proof device has a simple structure, and is convenient to use, and only with little added cost, the password keyboard peep-proof device can ensure that viewers behind a user cannot see the password inputted by the user under the premise of guaranteeing normal use; and moreover, the password keyboard peep-proof device provides the viewing assistance function for users with visual impairment, particularly patients with hyperopia.
Description
Technical field
The utility model relates to a kind ofly to be strengthened peep-proof and with the password keyboard peep-proof device of subsidiary function, is applied to the code keypad in the bank electric payment.
Background technology
At present bank cipher output with the common watching shield cover of keyboard can only guarantee from the place ahead, left, right-hand 3 directions realize protecting in the angle sight line to be blocked by Anti-peep baffle; then be easy to be observed above keyboard, this may be observed by people after one's death when causing the user to input password.
On the other hand, be subjected to the PCI specification limits, the digital keys zone of handheld device can not be greater than 7.62cm*10.16cm, and this has also limited button size, indirectly causes the client's (mainly being the farsightedness patient) who has defective vision can't see button clearly.Therefore, for the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of this utility model is to provide a kind of and strengthens peep-proof and with the password keyboard peep-proof device of subsidiary function, and it is good and use the problem such as inconvenience for the dysphotia user to help to solve the security of Current Password keyboard.
Of the present utility model being characterised in that: a kind ofly strengthen peep-proof and with the password keyboard peep-proof device of subsidiary function, comprise the code keypad main body, described code keypad main body comprises keyboard region and is arranged on keyboard region the place ahead, left, right-hand 3 the direction perimembranous and the Anti-peep baffle that links together, described the place ahead Anti-peep baffle has the curved portions that covers the keyboard region upper lateral part in order to it, it is characterized in that: the curved portions of described the place ahead Anti-peep baffle is connected with the lens that cover keyboard region; Anti-peep baffle on described 3 directions keyboard area peripheral part zone shape at 45 ° ~ 315 ° level spies on the dead angle.
Advantage of the present utility model: the utility model is simple in structure, and is easy to use, and the cost that only increases seldom just can solve under the prerequisite that guarantees the normal use of user, and user observer after one's death can't observe the details that the user inputs password; And for the user, particularly farsightedness patient of obstacle are arranged for eyesight, provide auxiliary overview function.

Fig. 2 is the side-looking structure cross-sectional schematic of the utility model embodiment.
Fig. 3 is the fundamental diagram of the utility model embodiment.
Embodiment
With reference to figure 1, Fig. 2 and Fig. 3, the utility model relates to a kind ofly strengthens peep-proof and with the password keyboard peep-proof device of subsidiary function, comprise code keypad main body 1, described code keypad main body comprises keyboard region 1-1 and is arranged on keyboard region 1-1 the place ahead, left, right-hand 3 the direction perimembranous and the Anti-peep baffle that links together, described the place ahead Anti-peep baffle 1-2 has the curved portions 1-2-1 that covers the keyboard region upper lateral part in order to it, and the curved portions of described the place ahead Anti-peep baffle 1-2 is connected with the lens 2 that cover keyboard region.
In order to prevent being spied at the level orientation upper keyboard, the Anti-peep baffle on above-mentioned 3 directions keyboard area peripheral part zone shape at 45 ° ~ 315 ° level spies on the dead angle.
Watched by the Password Input person in certain distance for the virtual image that guarantees lens formation, the focal length of said lens should be greater than lens and the interplanar distance of keyboard region button.
Use smoothly in order to ensure, said lens is convex lens; Equally, when lens are set to concavees lens or compound lens, as long as according to design concept of the present utility model, the parameter that needs are set also can reach requirement.
For embodiment carries out smoothly, the focal length of selecting said lens is 40cm, and the height of described Anti-peep baffle is 8cm, and described lens face is 8cm apart from the spacing on keyboard region button plane.
Specific implementation process: this device comprises an Anti-peep baffle and is installed in the lens of Anti-peep baffle top.
Further, described Anti-peep baffle is comprised of the baffle plate of 3 directions, surrounds around the digital keys scope of shown in figure one 45 °＜β＜315 °.(such as Fig. 1)
Further, lens closely are connected with the upper edge of above-mentioned Anti-peep baffle, do not have the space.
Further, the focal length of lens should be greater than lens and the interplanar distance of button, makes the user see through digital keys that lens see and presents and amplify the upright virtual image, because the virtual image, can be played the auxiliary effect of observing greater than the actual keyboard several times; Simultaneously since the virtual image greater than the actual keyboard several times, when observation point according to lens distance during greater than the focal length of lens, the virtual image be blocked part by Anti-peep baffle, make the observer can't see complete key face, such as Fig. 2.
Fig. 3 has described the principle of work of this device.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
