Abstract

一种可插入外壳中的光具座。
在一种激光唱机的扫描装置的外壳中就插有此类装有一组透镜或一个光栅的光具座。
为了易于制造和将其插入外壳(G)中，在光具座的一面(S2)上设置了一环形的弹性件(F)，它将光具座的另一面(S1)压靠在外壳的肩台上，因而无需其它的夹持或固定装置。该光具座可用成本低廉的注塑方式制造。
本发明的适用于光扫描装置，如激光唱机，录像机、光盘绘图机、磁光录放设备。

Description

本发明涉及一种可插入外壳中的光具座。
这样的光具座被使用在一种激光唱机的扫描装置，即所谓的光学唱针中。在这种光具座中装有透镜或光栅，而后将其插入光扫描装置的外壳中。
本发明的目的在于提供一种光具座的构造使其易于制造，并且同样能够插入光扫描装置的外壳中。
本发明目的是这样实现的，在光具座的一面至少设置一个弹性件，它位于光通道外侧，当光具座插入外壳中后，弹性件将光具座的另一面压靠在外壳的一肩台上。
如附图所示
图1是一个实施例的侧视图
图2是该实施例的剖面图
图3是该实施例的俯视图
图4是该实施例的仰视图
图5给出了该实施例如何装在外壳中。
下面对附图给出的实施例进行描述和解释：
图1所示为一圆柱形光具座，在其一面S1装有一光具L，如一个光栅或一组透镜，在另一面S2上有两窄条S，与一环形弹性件F相连，该弹性件朝内弯曲，在一侧面上有孔B，它的作用以后说明。图2是光具座的剖视图，由图1转动90°而得到。
在S1一面有一凹槽，可装入光栅或透镜L，中央部分为光通孔O，通孔O也可作为孔经光阑。
图3所示为已装有光具的光具座S1一面，图4则给出了带有弹性件F的另一面S2。
图5中，光具座已插入外壳G中，由于环形弹性件F将光具座的S1面压靠在外壳的一肩台面上，因此无需别的夹紧或固定装置。由于环形弹性件F呈曲面状，所以光具座可在外壳G中旋转，以此调整光栅L，孔B即是为了用一特殊工具调整光栅L而设置的。
本发明的主要优点，可以看出，就是可用塑料制成一注塑件，生产成本明显低于由多个部件组成的光具座。
本发明适用于光扫描装置，例如在激光唱机，录像机，光盘绘图机或磁光录放设备中。

Claims (2)

1、一种用于插入外壳(G)中的具有光具(L)(如一个透镜或光栅)的光具座，其特征在于：至少在光具座的一面(S2)上有一弹性件(F)，该弹性件装在光束通道外侧，即将光具座另一面(S1)压靠在外壳(G)的一肩台上，在光具座的一侧面上装有孔(B)，用于调整光具(L)，弹性件(F)呈环形曲面状，通过两窄条(S)与光具座的一面(S2)相连，窄条(S)相对设置，环形弹性件(F)由该窄条(S)处呈曲面状向外延伸，其支撑点位于与环形弹性件(F)同一直径的圆周上。
