Abstract

本实用新型涉及的防窥密码输入器,包括由按键构成的键盘及由按键控制的输入电路;其特征是:按键外侧为非透明面(2),中间为透明体或球面向下的凸透镜体(3),透明体下方或凸透镜体下方成像距离内具有字符显示载体(5),按键的底部具有输入电路的导电橡胶(7)。本实用新型的键盘按键与普通密码键盘的设置方式一致,使用一样方便。但由于采用凸透镜成像及视角差原理设计按键,只有使用者垂直正视,才能看清按键内的数字符号,偏离一定的角度,则看不见完整的数字符号,或者因变形而无法识别的数字符号,从而保证了输入的密码不被他人窥视,窃取。

Description

防窥视密码输入器
技术领域
本实用新型涉及键盘输入装置,具体是一种适用于商场、银行、税务、海关、邮电等采用电子商务的部门使用的的防窥视密码输入器。
技术背景
随着社会经济活动的发展和电子商务的普及,人们使用密码和个人资料的机率越来越大。而与人们经济生活息息相关的许多场合,如商场、银行、税务、海关、邮电等又多是人群密集的公共场所。当人们在这些公开场合使用目前的输入键盘输入姓名、地址、账号、金额、日期等个人资料和密码时,容易被他人知晓、窥视,或窃取,造成泄密。虽然许多单位、部门和机构都采取了很多防范措施,但是,都未能很好地解决问题。用户的个人资料及密码被窃取、被泄露的事件时常发生,这给国家、集体和个人的财产带来不小的损失。
发明内容
本实用新型所要解决的技术问题是:提供一种按键采用凸透镜成像及视角差原理进行设计的防窥密码输入器。
为解决上述技术问题,本实用新型采用的技术方案是这样的,即一种防窥密码输入器,包括由按键构成的键盘及由按键控制的输入电路;其特征是:按键外侧为非透明面,中间为透明体或球面向下的凸透镜体,透明体下方或凸透镜体下方成像距离内具有字符显示载体,按键的底部具有输入电路的导电橡胶。
本实用新型由于采用凸透镜成像及视角差原理设计按键,使使用者在输入密码时,只能垂直正视,才能通过透明体或凸透镜看清楚按键内显示载体显示的数字;偏离一定的角度则形成视角差或焦距改变,按键内显示的字符会呈现看不见,看不全面,甚至只能看见因变形而无法辨认的字体,保证输入的密码不会被人窥视而失窃。
附图说明
附图为本实用新型实施例的结构示意图。
参见附图:图中1—按键、2—按键非透明面、3—透明体或凸透镜、4—按键内的空腔、5—字符显示载体、6—按键脚、7—导电橡胶、8—电路板。
具体实施方式
本实用新型的结构可以通过附图给出的实施例进一步说明。
参见附图:图中给出的实施例中,按键(1)用透明有材料制作,按键顶端全透明,按键外侧的非透明面(2)为经过磨砂处理而构成模糊面。按键(1)的顶端面为下凹弧面,按键中间为透明体或凸透镜体(3),透明体下方或透镜体球面下方为空腔(4),空腔底部的字符显示载体(5)为数码管,以保证在任何环境下数字显示清楚,容易辨识,数码管与电路板(8)连接成一体;各按键内数码管显示的字符的排列可以不同于目前数字键盘的排列顺序,或显示数字的顺序可以改变。输入指令由按键按压导电橡胶导通电路实施,并由电路驱动数码管显示。在本实施例中,按键通过按键脚(6)与导电橡胶(7)接触。
字符显示载体也可以是印有字符的卡片。
