Problems solved by technology

However, since the display portion 20 of the conventional device is installed externally, it is easy to expose the password data input by the user to strangers.
For example, in the case where a conventional device for inputting a password is applied to an automatic door device, the user will touch specific keys corresponding to the fixed password, and this will cause a serious problem that the specific keys repeatedly touched by the user will Appearance is different from other unused keys

Embodiment Construction

[0022] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0023] now refer to figure 2 , shown in this figure is the front panel of the password input device according to the present invention, wherein the password data is only composed of numbers 0 to 9, and the basic concept of the present invention will be described below.

[0024] The password input device includes a display section 30 for displaying password data of numerals 0 to 9, respectively, and a plurality of selection keys 40 for selecting the password data displayed on the display section 30. Here, the arrangement of the password data displayed on the display section 30 is changed every time the user inputs the password. For example, when the user starts to operate the device, the password data on the upper part of the display part 30 shows "03957", while the password data on the lower part of the display part 30 s...

Abstract

Disclosed relat to a password input apparatus that prevents the exposure of password to strangers while the user inputs the password, furthermore, prevents strangers from perceiving the password easily through distinctions of specific keys corresponding to the password due to repeated use. According to the invention, a series of password data (random digit string) are displayed on display elements (33) and the password data displayed are selected using selection keys (40) by a user. Here, the arrangement of the password data is varied every time when the user inputs the password. A display window (32), having a predetermined height, provided on the top of the display element (33), can narrow the angle of view against the light emitted from the display elements (33), thus preventing strangers other then the users standing in a straight line against the display element (33) from perceiving the passwordk easily.

Description

technical field [0001] The present invention relates to a password input device, in particular to a password input device that can prevent the password from being exposed to strangers when the user inputs the password. The password is detected by the difference of the specific keys corresponding to the password. Background technique [0002] Recently, various devices that require a user to provide a password to operate have been developed and widely used. For example, automatic door devices for opening doors and automatic teller machines (ATMs) are typical examples of password entry devices where a user withdraws his or her cash from the ATM rather than from a bank. [0003] figure 1 Shown is a conventional device front panel for entering a password, which includes a numeric keypad 10 and a display portion 20 for displaying password data entered by the user, wherein the numeric keypad has a plurality of selection keys, such as for entering corresponding Numeric keys for p...
