Description

摄象机及其取景器
本发明涉及一种摄象机,并且更具体地涉及一种能够为使用者提供清晰图象的摄象机的取景器。
一般来说,摄象机包含具有摄象部分的主体,该摄象部分从景物感光;以及安装在主体上的取景器。取景器具有阴极射线管(CRT)、镜头和目镜框,因而使用者能够观察到摄象部分摄取的景物的图象。在这种传统的取景器中,镜头很容易受到进入到目镜框中的污物的污染。这种污染造成了麻烦,因为镜头的清洗经常是很麻烦并费时的。
因此,本发明的主要目的在于,提供一种具有防护罩的摄象机的取景器,该防护罩能够阻止污物进入到镜头里边。
本发明的上述及其它目的是通过提供一种用于显示图象的摄象机的取景器来实现的,该取景器包含:用于放大图象的镜头;其中装有镜头的外壳;安装于外壳上的目镜框以及可折卸地安装于目镜框中的防护罩,该防护罩防止污物进入到目镜框中。
也就是说,本发明提出了一种用在摄象机中用来显示图象的取景器,该取景器包含:一用于放大图象的镜头;一容置镜头的外壳;一装于外壳上的目镜框;可拆卸地装于目镜框中的防护罩,该防护罩防止污物进到取景器中。
一种摄象机,该摄象机包含:具有用于从景物感光的摄象部分的主体;可拆卸地装于摄象部分的摄象镜头盖;安装于主体侧面的把手,其用于方便地抓紧摄象机;安装于主体上的取景器,用于显示景物的图象,其中,所述取景器包含:一用于放大图象的镜头;一容置镜头的外壳;一装于外壳的目镜框;可拆卸地装于目镜框中的防护罩,以防止污物进到取景器中。
其中所述摄象镜头盖至少设置一对嵌块,该嵌块用于在摄象机使用时将防护罩啮合于其中。
其中所述把手具有一支架,其上可悬挂与摄象镜头盖啮合的防护罩。
本发明的上述及其它目的,优点及其特点将从下面的结合附图对优选实施例的详细描述中显示出来。
这些附图是:
图1是根据本发明摄象机的立体示意图;
图2是图1中所示的取景器的剖面示意图;
图3是图2中描绘的防护罩的立体图;
图4是图1中所示的摄象镜头盖的立体图;
图5是图1中表示的支架的立体图;
图6是悬挂到支架上的防护罩和摄象镜头盖的剖面图。
参见图1,摄象机10包含主体12,该主体12上具有从景物感光的摄象部分14;取景器16,其为使用者提供摄取到的景物的图象。摄象机10还具有把手18,该把手18安装于主体的侧面,为了便于握持或抓紧摄象机10。摄象部分14具有为了从景物采光的物镜组(未示出);将光转换为电信号的电荷耦合器(未示出);防护物镜组的摄象镜头盖。取景器16可转动地安装在主体12上以便围绕其支承部向上旋转,该取景器与摄象部分14作电连接。
如图2所示,取景器16包含:阴极射线管(CRT)22,镜头24,目镜框28及防护罩32。阴极射线管22将电信号生成图象,该电信号来自摄象部分14;镜头24放大形成在阴极射线管22的荧屏上的图象,镜头24和阴极射线管22容置于取景器16的外壳26中。目镜框28可拆卸地安装到外壳26上,该目镜框由橡胶材料制成。防护罩32紧密地装到目镜框28中以形成阻止污物如灰尘进入的屏障从而保护镜头24不被污染。目镜框最好具有从其内表面凸出的挡块以防止防护罩32被过分插入。
参见图3,接合凸出部34从防护罩32的中心部延伸,该凸出部34为了便于在摄象前将防护罩32取出。连线38与摄象机10的适当部位如把手18和摄象镜头盖40相连,该连线38被装到凸出部34上。凸出部34具有防止连线滑脱的法兰36。防护罩可以是圆形。然而,可以理解的是,防护罩32可以根据目镜框28相应的断面设置成其它形状。
摄象镜头盖40可以具有一对或多对相对立地定位嵌块42,如图4所示。每一嵌块42从摄象镜头盖40的内表面伸出并具有半圆形的倒钩44,该倒钩44在嵌块42的端部径向地向内凸出。在嵌块42靠近于摄象镜头盖的内表面的两个相对立地定位嵌块42之间的距离大于防护罩32的直径,而在倒钩44的顶部小于防护罩32区域的直径。这种结构允许防护罩32与摄象镜头盖40啮合而不会从中滑脱就象所希望的那样。摄象镜头盖40最好由有弹性的塑料树脂制成。
防护罩32与镜头盖40啮合在一起可以被悬挂到支架50上,如图5所示。支架50安装到把手18上,该支架50包含一前壁52和一对侧壁56,从而限定一能够容置防护罩32’的法兰36的腔。凹缺54设置在前壁52上,因而凸出部34被插入其中,法兰36进入到腔中并与前壁52的内表面接触。
当摄象机10被使用时,防护罩32与摄象镜头盖40啮合而被挂到支架50上,如图6所示。
尽管本发明结合典型实施例被示出及描述,但是,可以理解对本发明所作的各种改型、变化及补充都没有脱离本发明的精神和保护范围。
