Abstract
The invention relates to a code keypad peep prevention device with a peep prevention strengthening function and an auxiliary function. The code keypad peep prevention device comprises a code keypad main body. The code keypad main body comprises a keypad area and peep prevention baffle plates, wherein the peep prevention baffle plates are arranged on the peripheries of the front, the left and the right of the keypad area; and the front peep prevention baffle plate is provided with an arc-shaped part which is used for shielding the upper side of the keypad area. The code keypad peep prevention device is characterized in that the arc-shaped part of the front peep prevention baffle plate is connected with a lens for shielding the lens area. The code keypad peep prevention device is simple in structure and convenient to use, cost is increased a little, but an observer behind a user cannot observe the detail of codes inputted by the user on the premise that the user uses a code keypad normally. Besides, the code keypad peep prevention device has an auxiliary observation function for visually handicapped users, particularly patients suffering from presbyopia.
Description
Technical field
The present invention relates to a kind ofly strengthen peep-proof and, be applied to the code keypad in the bank electric payment with the code keypad peep-proof device of miscellaneous function.
Background technology
Bank cipher output at present 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 the peep-proof baffle plate; Above keyboard, then be easy to be observed, possibly observed by people after one's death when this inputs password with regard to causing the user.
On the other hand, receive 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, causes the client's (mainly being the farsightedness patient) who has defective vision can't see button clearly indirectly.Therefore, are objects that the present invention studies to the problems referred to above.
Summary of the invention
The object of the present invention is to provide and a kind ofly strengthen peep-proof and with the code keypad peep-proof device of miscellaneous function, it is good and use problems such as inconvenience for the dysphotia user to help to solve the fail safe of Current Password keyboard.
The invention is characterized in: a kind ofly strengthen peep-proof and with the code keypad peep-proof device of miscellaneous function; Comprise the code keypad main body; Said 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 peep-proof baffle plate that links together; Said the place ahead peep-proof baffle plate 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 said the place ahead peep-proof baffle plate is connected with the lens that cover keyboard region.
Advantage of the present invention: the present invention 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, auxiliary overview function is provided for the user, particularly farsightedness patient of obstacle are arranged for eyesight.
Description of drawings
Fig. 1 is the anti-shielding angle degree sketch map of spying on of the embodiment of the invention.
Fig. 2 is the side-looking structure cross-sectional schematic of the embodiment of the invention.
Fig. 2 is the fundamental diagram of the embodiment of the invention.
Embodiment
With reference to figure 1; Fig. 2 and Fig. 3; The present invention relates to a kind ofly strengthen peep-proof and with the code keypad peep-proof device of miscellaneous function, comprise code keypad main body 1, said 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 peep-proof baffle plate that links together; Said the place ahead peep-proof baffle plate 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 said the place ahead peep-proof baffle plate 1-2 is connected with the lens 2 that cover keyboard region.
In order to prevent to be spied at the level orientation upper keyboard, the peep-proof baffle plate on above-mentioned 3 directions is spied on the dead angle in the level of 45 ° ~ 315 ° of keyboard area peripheral part zone formation.
Watched by the password importer 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,, the parameter that needs are set also can reach requirement as long as according to design principle of the present invention.
For embodiment carries out smoothly, the focal length of selecting said lens for use is 40cm, and the height of said peep-proof baffle plate is 8cm, and said lens face is 8cm apart from the spacing on keyboard region button plane.
The practical implementation process: this device comprises a peep-proof baffle plate and the lens that are installed in peep-proof baffle plate top.
Further, said peep-proof baffle plate is made up of the baffle plate of 3 directions, surrounds around the digital keys scope of shown in figure one 45 °＜β＜315 °.(like Fig. 1)
Further, lens closely are connected with the upper edge of above-mentioned peep-proof baffle plate, 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 appears 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 point of observation according to lens distance during greater than the focal length of lens, the virtual image blocked part by the peep-proof baffle plate, make the observer can't see complete button face, like Fig. 2.
Fig. 3 has described the operation principle of this device.
The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
