Description

一种防窥密码输入键盘
技术领域
本发明涉及一种密码输入器, 特别是涉及一种防窥密码输入键盘。
背景技术
为了防止他人窥探, 现有的密码输入器一般都是在按键周围设置向上凸出 以挡住光线的边框, 但是当使用这种设有挡光边框的密码输入器时, 如果使用 者将手全部放入边框内, 就会感到操作十分不便, 而如果使用者用较少的手指 按压输入键, 则很容易被他人得知所按的密码。 另外, 由于这种密码输入器上 的输入键位置是固定的且具有一定的排布规律, 因此偷窥的人很容易根据手指 的位置判断出所输入的密码。
发明内容
为了解决上述问题, 本发明的目的在于提供一种在一定的距离内只有密码 输入者能够看到显示器内容的防窥密码输入键盘。
为了达到上述目的, 本发明提供的防窥密码输入键盘包括多个按键、 不透 明壁和显示器; 所述的显示器用于显示数字、 文字及各种图形符号; 不透明壁 竖立设置在显示器的上方; 而多个按键则安装在不透明壁的上端, 其由透明材 料制成,并且每个按键和不透明壁与显示器上每个数字或文字显示部位相对应。
所述的不透明壁由垂直设置的多条纵向壁构成。
所述的多条纵向壁之间的间距小于 5毫米, 高度小于 20毫米。
所述的不透明壁由垂直设置的多条纵向壁及多条横向壁呈网格状连接而构 成。
所述的多条纵向壁之间的间距小于 5毫米, 高度小于 20毫米; 多条横向壁 之间的间距小于 5毫米, 高度小于 20毫米。 所述的不透明壁由具有倾角的多条纵向壁构成, 其中位于中间的纵向壁上 端向外倾斜, 而位于两侧的纵向壁上端则向内倾斜。
所述的不透明壁由具有倾角的多条纵向壁及多条横向壁呈网格状连接而构 成, 其中位于中间的纵向壁和横向壁上端向外倾斜, 而位于两侧的纵向壁和横 向壁上端则向内倾斜。
所述的不透明壁上位于外侧的纵向壁或横向壁上端高度高于位于内侧的纵 向壁或横向壁上端高度。
本发明提供的防窥密码输入键盘包括多个按键、 不透明壁和显示器; 所述 的显示器用于显示数字、文字及各种图形符号; 多个按键安装在显示器的上部, 其由透明材料制成,而且每个按键与显示器上每个数字或文字显示部位相对应; 而不透明壁则竖立设置在多个按键的内部。
所述的不透明壁由垂直设置的多条纵向壁构成。
所述的多条纵向壁之间的间距小于 5毫米, 高度小于 20毫米。
所述的不透明壁由垂直设置的多条纵向壁及多条横向壁呈网格状连接而构 成。
所述的多条纵向壁之间的间距小于 5毫米, 高度小于 20毫米; 多条横向壁 之间的间距小于 5毫米, 高度小于 20毫米。
所述的不透明壁由具有倾角的多条纵向壁构成, 其中位于中间的纵向壁上 端向外倾斜, 而位于两侧的纵向壁上端则向内倾斜。
所述的不透明壁由具有倾角的多条纵向壁及多条横向壁呈网格状连接而构 成, 其中位于中间的纵向壁和横向壁上端向外倾斜, 而位于两侧的纵向壁和横 向壁上端则向内倾斜。
所述的不透明壁上位于外侧的纵向壁或横向壁上端高度高于位于内侧的纵 向壁或横向壁上端高度。 本发明提供的防窥密码输入键盘具有如下优点:其可以利用不透明壁使得 在一定的距离内只有密码输入者能够看到显示器的内容, 因此防窥效果更好, 并且结构设计合理,输入方便。
附图说明
图 1 为本发明提供的防窥密码输入键盘实施例 1结构示意图。
图 2 为图 1中 A-A向剖视图。
图 3 为本发明提供的防窥密码输入键盘实施例 2结构示意图。
图 4 为图 3中 B-B向剖视图。
具体实施方式
下面结合附图和具体实施例对本发明提供的防窥密码输入键盘进行详细说 明。
实施例 1:
如图 1〜图 2所示, 本实施例提供的防窥密码输入键盘 1包括多个按键 2、 不透明壁 3和显示器 4; 所述的显示器 4用于显示数字、 文字及各种图形符号, 不透明壁 3竖立设置在显示器 4的上方, 而多个按键 2则安装在不透明壁 3的 上端, 其由透明材料制成, 并且每个按键 2和不透明壁 3与显示器 4上每个数 字或文字显示部位相对应; 其中不透明壁 3由垂直设置的多条纵向壁 7构成, 多条纵向壁 7之间的间距小于 5毫米, 高度小于 20毫米; 或由垂直设置的多条 纵向壁 7及多条横向壁 8呈网格状连接而构成, 多条纵向壁 7之间的间距小于 5毫米, 高度小于 20毫米; 多条横向壁 8之间的间距小于 5毫米, 高度小于 20 毫米。 另外, 位于外侧的纵向壁 7或横向壁 8上端高度高于位于内侧的纵向壁 7或横向壁 8上端高度, 并且纵向壁 7和横向壁 8具有一定的倾角, 其中位于 中间的纵向壁 7和横向壁 8上端向外倾斜, 而位于两侧的纵向壁 7和横向壁 8 上端则向内倾斜, 这样可以起到更好的防窥作用。 另外, 不透明壁 3与显示器 4 之间具有一定的间隙, 以便于光线进入, 当然还可以在此间隙处设置照明用 灯。
使用时显示器 4上随机显示出数字 1至 9, 受不透明壁 3的阻挡, 这些数 字只能在一定的范围内才可以看到, 因此除了密码输入者能够看到显示器 4上 显示的数字外, 两侧的人都无法看到显示器 4的内容。 另外, 由于显示器 4上 显示的数字是随机排布的, 因此其它人仅根据按键的位置也不能判断出输入的 数字, 由此达到保密的目的。
本实施例中, 可通过调节纵向壁 7和横向壁 8高度和密度的方法将防窥密 码输入键盘 1制得很薄, 因此适合银行柜台使用。
实施例 2 :
如图 3〜图 4所示, 本实施例提供的防窥密码输入键盘 6包括多个按键 5、 不透明壁 3和显示器 4; 所述的显示器 4用于显示数字、 文字及各种图形符号; 多个按键 5安装在显示器 4的上部,其上层是由玻璃或树脂等硬透明材料制成, 下层为透明硅胶弹性垫, 并且每个按键 5与显示器 4上每个数字或文字显示部 位相对应; 不透明壁 3设置在多个按键 5的内部, 其结构同实施例 1。
本实施例提供的防窥密码输入键盘 6与实施例 1提供的防窥密码输入键盘 1使用方法相同。 另外, 由于由玻璃或树脂材料制成的按键 5很结实, 因此本 实施例提供的防窥密码输入键盘 6适用于自动取款机。
另外, 本发明提供的防窥密码输入键盘 1, 6中的显示器 4和按键 2, 5上 包括有相关的电路、 电缆等部件, 并且能够实现图像显示和接受按键信号的功 能。 此外, 图 1〜图 4均为本装置的示意图, 因此图中的显示器 4和按键 2, 5 没有反映出线缆、 电路板等部件, 而是作为一个整体画出。
实施例 1中的按键 2可以采用各种现有的感应、 触摸结构等原理的透明按 键。 实施例 2中的按键 5可以是由多片树脂片表面磨砂后粘贴而形成, 由 于粘贴处经过磨砂而呈不透明状态, 这样自然就形成了不透明壁 3 ; 也可以用特定的材料在按键 5的内部利用诸如激光等处理方法直接形成不透明 壁 3;或将不透明薄片利用镶嵌方式一体注塑在按键 5的内部而形成不透明壁 3。
另外, 实施例 2中的按键 5还可以由软透明塑料一体制成, 不透明壁 3嵌 入在该塑料中。
显示器 4可以采用各种现有自发光或不发光的显示器。 当然对于不发光的 显示器, 可以在防窥密码输入键盘 1, 6内安装灯光照明装置。
上述实施例 1和 2中的纵向是指面对显示器 4时基本上垂直于人双眼连线 的方向, 而横向则是指基本平行于双眼连线的方向。 由于偷窥基本上是从两侧 方向, 而前后方向的可能性很小, 所以只设置纵向壁 7是最简单的一种, 如果 需要再加入横向壁 8, 当然为了美观, 实际使用时还可以将这些壁制成诸如椭 圆形等复杂的形状。
另外, 为了便于说明, 附图中将不透明壁 3上的纵向壁 7和横向壁 8画得 很厚, 实际上越薄越好。
以上所述仅是本发明提供的防窥密码输入键盘的实施例而已, 并非对其形 状、 材料和结构作任何形式上的限制, 凡是依据上述技术内容对其进行的任何 简单修改, 等同变化与修饰均属于本技术方案的范围之内。
