    • A picture frame size changing device for a lens-fitted photographic film unit has a pair of exposure aperture masking plates which are pivotally mounted in a light-shielding box disposed in front of an exposure aperture. The masking plates define a picture frame size which has a different aspect ratio from that of the exposure aperture. A finder mask is mounted on a front cover of the film unit, which is manually operable to be inserted in front of an objective window of a viewfinder. A lever mechanism for interconnecting the finder mask with one of the mask plates is mounted on the outside of the light-shielding box. The light-shielding box is incorporated into a photograph-taking unit having an exposure mechanism and a viewfinder optical system mounted thereon.
    • 用于带镜头的摄影胶片单元的相框尺寸改变装置具有一对曝光孔掩模板,它们被枢转地安装在设置在曝光孔前面的遮光箱中。 掩模板定义了与曝光孔径不同的纵横比的相框尺寸。 取景器面罩安装在胶片单元的前盖上,其可手动操作以插入取景器的客观窗口的前面。 用于将取景器掩模与其中一个掩模板互连的杠杆机构安装在遮光箱的外侧。 遮光盒被并入具有安装在其上的曝光机构和取景器光学系统的摄影单元。

    • In a film unit, a charge operation member is held on a fron side of a guide member to be slidable between an ON position to turn on a flash charge switch of a built-in flash device and an OFF position to turn off the flash charge switch. The guide member is mounted stationarily to a front side of a flash circuit board of the flash device. Joints between front and rear cover of the film unit are set away from those circuit portions of the flash device where high voltage current flows. The flash charge switch is constituted of a metal contact blade and contact chips provided on the flash circuit board. The metal contact blade is bent roundly at a base portion of a pair of resilient arms. The charge operation member keeps on pressing the arms onto the contact chips in the ON position. The flash device charges a main capacitor while the flash charge switch is on, and automatically stops charging when the charge voltage goes above a predetermined voltage. A light emitting diode indicates the completion of charging.
    • 在胶片单元中,充电操作构件被保持在引导构件的前侧,以在ON位置之间滑动以接通内置闪光装置的闪光充电开关和OFF位置,以关闭闪光充电 开关。 引导构件固定地安装在闪光装置的闪光电路板的前侧。 胶片单元的前盖和后盖之间的接头远离高压电流流动的闪光装置的那些电路部分。 闪光充电开关由金属接触片和设置在闪光电路板上的接触芯片构成。 金属接触片在一对弹性臂的基部弯曲成圆形。 充电操作构件将接触片上的臂按压在ON位置。 闪光灯装置在闪光充电开关打开时对主电容器充电,并且当充电电压超过预定电压时自动停止充电。 发光二极管指示充电完成。
