BACKGROUND OF THE INVENTION
The present invention relates to an information input device capable of preventing a selected input key from being stolen when inputting a personal identification number or the like.
[0002]
[Prior art]
With the recent development of technology, electronic payment using a credit card, a cash card, the Internet, or the like is performed, and the electronic payment system receives cash and provides a specific service. This electronic settlement system performs security management by allowing an ATM or the like to read magnetic information generally attached to the card, or by inputting a password after inputting a card number.
[0003]
Also, in the US, when using a public telephone, there is a service in which if a calling card number issued by a telephone company is entered, it can be made without coins, and the claimant is mailed at a later date. The input of the card number (password) that only the person knows provides the security in this service.
[0004]
However, in general, a key for inputting a personal identification number provided in an ATM or the like has a fixed arrangement of numbers 1 to 9 and 0, and symbols * and # in 3 columns and 4 rows (ISO9564-1 Annex F). For example, even if information such as numbers displayed on the key you are entering cannot be recognized, the information such as the entered password will be detected from the movement of your finger. Therefore, information such as a personal identification number inputted from a remote location may be stolen.
[0005]
In order to solve such a problem, there is an information input device configured to display input keys on a liquid crystal touch panel and change the arrangement of the input keys at random. By changing the arrangement of the input keys at random, It is possible to prevent the number from being seen.
[0006]
[Problems to be solved by the invention]
However, when the input keys are arranged at random, there is a high possibility that the input will be wrong, and the liquid crystal touch panel is expensive, so the information input device becomes expensive.

Therefore, an object of the present invention is to provide an inexpensive information input device capable of preventing the input key information from being stolen and the erroneous input when inputting a personal identification number or the like.
[0008]
[Means for Solving the Problems]
The present invention has been made to achieve the above object, and is an information input panel having a plurality of input keys on which information is displayed, and information recognition for recognizing information on an input key selected from the input keys. The information input panel is configured to be rotatable around a predetermined axis, and the input keys are arranged along a circumference around the axis. It is characterized by that.
[0009]
As described above, according to the present invention, the position of the input key can be changed by rotating the information input board before and after inputting information such as a password into the information input device. It is difficult to recognize input information from the movement of the finger. In addition, since the input keys are arranged in the same circular direction as the direction of change, the input keys are not destroyed and erroneous input is rarely caused.
[0010]
In the information input device according to the present invention, the information recognition means is selected as a reference information recognition means for recognizing an input key existing at a specific reference position, and a reference input key recognized by the reference information recognition means. Selection information for recognizing information on the input key selected from the relative position recognition means for recognizing the relative position relationship of the input key, the information on the reference input key, and the relative position relationship between the reference input key and the selected input key In this case, each of the input keys is provided with an identification display for identifying the input key, and the reference information recognition means is located at a specific reference position. It is preferable that the reference input key information is recognized by recognizing the identification display of the input key. The identification display includes a plurality of binary coded reflective portions provided on the back surface of each input key corresponding to the information of each input key, and the reference information recognition means includes the plurality of reference information recognition means. It is preferable to include an optical detection means arranged to face the reflecting portion.
[0011]
Furthermore, in the information input device according to the present invention, it is preferable that the information displayed on the input key is displayed by unevenness. In this way, by displaying the information displayed on the input key with unevenness, even a blind person can recognize the information on the input key and perform input operations without the help of others. it can. Examples of the information displayed on the projections and depressions include Braille or normal characters, numbers or symbols displayed with projections and depressions.
[0012]
Further, the information input device according to the present invention is an information input device including a touch panel for displaying an input key on which information is displayed. The input keys are displayed on the same circumference without changing their arrangement. The input key is configured to be rotated and displayed in the circumferential direction of the circle on which the input key is displayed.
[0013]
As described above, according to the present invention, since the input key is displayed with its position changed, it is difficult to recognize the input information from the movement of the finger inputting the encryption number. Further, since the input keys are displayed with their positions changed without changing their arrangement on the same circumference, there is little possibility of erroneous input.
[0014]
The input keys are preferably displayed in order on the same circumference, and when the user touches a predetermined position on the touch panel, the input keys are displayed without changing their arrangement. It is preferable that the display is rotated in the circumferential direction.
