Abstract
The utility model relates to a cipher inputting anti-theft device which comprises a cipher generating controller, a figure display screen, figure selecting keys, a confirming key and a sealed outer cover, wherein the figure display screen, the figure selecting keys, the confirming key and the cipher generating controller are connected with each other by control lines, and the figure displaying home position of the figure display screen is arranged to be random; an observation hole is arranged on the outer cover. When ciphers are input, the selecting keys can be pressed to select figures and then the confirming key is pressed for confirmation. Because the figure display of the figure display screen can be seen only through the observation hole on the outer cover, without being seen by other people who can not see that the figure displaying original position of the figure display screen is random, people can not verdict input characters by users even though the number of times for pressing the selecting keys and the confirming key is seen, and accordingly, the utility model can achieve the aim of confidentiality.
Description
Technical field
The utility model relates to a kind of password input anti-theft arrangement.
Background technology
At present, bank debits and automated teller automatic teller machine, proof box (cabinet), storage tank (cabinet), password door etc. all are provided with the encrypted message input unit, but these PIN PAD all are made up of the character keys of open type.When the user on keyboard when input digit password or other character informations, people on every side or thing (first-class as making a video recording) can clearly be observed operator's hand motion and import which character information, the password that is provided with of user is just revealed away like this.The offender peeps the password that mode is stolen the victim by this just, thereby steals the property of victim or country, and this causes damage not only for the country and people's property, and causes social destabilization.
The utility model content
The purpose of this utility model just provides the password input anti-theft arrangement that a kind of other people can't peep the information of being inputed.
For achieving the above object, password input anti-theft arrangement of the present utility model is characterized in that: comprise password generator controller, digital display screen, digital selective key, acknowledgement key and closed cover; Described digital display screen, digital selective key, acknowledgement key have control line to be connected with the password generator controller, and the numeral of described digital display screen shows that the original position is made as at random, and described outer cover is provided with viewport.
On the basis of the above, the utility model also can have various scheme forms:
Described viewport is positioned at the front of the thief-proof input media of password, and viewport is provided with lens.
The beneficial effects of the utility model are: when needs input password, people can press digital selective key according to the demonstration of the numeral on digital display screen original position and select numeral, pressing acknowledgement key again confirms to pass through password generator controller generation password, because showing, the numeral of digital display screen can only see that other people can't see by the viewport on the outer cover, and original position that can't see the numeral demonstration of digital display screen because of other people is at random, so even if thereby see that you can't judge by the number of times of options button and acknowledgement key which type of character you import and reach secret purpose.

Embodiment
As shown in Figure 1 to Figure 3, the password of the utility model embodiment 1 input anti-theft arrangement is made of password generator controller, digital display screen, digital selective key, acknowledgement key and closed cover; Digital display screen, digital selective key, acknowledgement key has control line to be connected with the password generator controller, digital transversely arranged on this routine digital display screen, digital selective key divides left to the right totally two, acknowledgement key is in the middle of two digital selective keys, the outer cover that covers on the digital display screen is provided with viewport, the hole is provided with lens, correspondence is provided with pilot lamp and with viewport certain distance is arranged below the numeral on the digital display screen, the numeral of digital display screen shows that the original position is made as at random, the password generator controller will be provided with numeral demonstration original position again at random after promptly pressing acknowledgement key at every turn, and these are existing technology.Because the setting of lens according to human eye subtense angle and optical perspective principle, makes the other people of visual angle beyond 10 degree can't see the inside content clearly, the operator who only is in the vertical angle of view just can see.Digital selective key about pressing makes the pilot lamp below 0 to 9 numeral single thereupon glittering by the password generator controller, whenever pressing digital selective key once, pilot lamp just moves one, when moving on to the character that you need just once by acknowledgement key, first code characters and note exist on the password generator controller, press directionkeys again and move on to required character position again by the 3rd of acknowledgement key, the 4th when second code characters of input ... so analogize.
The outer cover 1 of embodiment 1 is positioned at the positive top of PIN PAD and is connected as a single entity with panel 10, outer cover 1 positive place is provided with a viewport 2, viewport 2 belows are provided with one group of 0-9 numeral 3, numeral 3 has one group and digital corresponding LED pilot lamp 4, be provided with lens 5 above the viewport 2, it is the focal length of lens 5 just in time that numeral 3 and luminotron 4 leave lens 5 distances, makes that anyone can not see numeral 3 from this window except the operator.Panel 10 is provided with digital selective key 7 (left), digital selective key 8 (to the right), and acknowledgement key 6.Password generator controller 9 is positioned at the panel after-frame, and Fig. 3 is the synoptic diagram that password generator controller 9 is connected with digital selective key 7, digital selective key 8, LED light 4.
Operating process is as follows: to make the pilot lamp 4 of numeral below 3 (0 to 9) pass through password generator controller 9 single thereupon glittering when pressing digital selective key 7 and digital selective key 8, whenever pressing directionkeys once, pilot lamp just move one bright, when moving on to the character that you need just once by acknowledgement key 6, first code characters existed on the password generator controller by note, press digital selective key 7 or digital selective key 8 during second code characters again when input and move on to required character position again by 6, the three of acknowledgement keys, the 4th ... so analogize.Password generator controller 9 can pilot lamp initial bright spot be set to random site, others see you by the directionkeys and the number of times of acknowledgement key all can not differentiate your character of input and reach secret purpose.
Operating process is as follows: when turn options button 13 up and down, dial arm 14 just touch digital selector button 7 and digital selector button 8 make nixie display 3 change 0 to 9 digital glittering, the numeral that being screwed into the operator needs is just pressed and is selected knob 13 shake-up ACK button 6.
Fig. 6, Fig. 7 are embodiment 3 of the present utility model, outer cover 1 is a spherical, viewport 2 is circular, numeral 3 and pilot lamp 4 are circular arrangement, numeral 3 is for making by light transmissive material, pilot lamp 4 places below the corresponding numeral 3, and outer cover 1 is not connected as a single entity and can stirs by free non-directional with panel 10, makes the operator so that regulate visible angle.Panel 10 is provided with rotary selection knob 11 and circular key 12, and rotary selection knob 11 is connected with one group of arm 14.
Operating process is as follows: when the selection knob 11 that rotates about, group arm 14 just touches digital selector button 7 and digital selector button 8 makes 0 to 9 numeral of digital display lamp 4 single glittering, and the numeral that being screwed into the operator needs is just pressed circular key 12 and touched ACK button 6.
