摘要： In a lens-fitted photographic film unit, a connection lever makes one reciprocating movement when struck by a shutter actuating lever. The reciprocating movement of the connection lever is transmitted to a crank lever to a pair of shutter blades to cause the shutter blades to open and then close a shutter aperture. The connection lever is coupled to the crank lever through a connection pin and a cam slot. The cam slot has an actuating portion and a keeping portion. While the connection pin moves along the actuating portion, the movement of the connection lever is transmitted to the shutter blades through the crank lever to open and close the shutter aperture. While the connection pin moves along the keeping portion, the movement of the connection lever is not transmitted to the shutter blades so that the shutter blades are kept in the opened position.
摘要翻译：在装有镜头的摄影胶片单元中，当由快门驱动杆撞击时，连接杆进行一次往复运动。连接杆的往复运动传递到曲柄杆到一对快门叶片，以使快门叶片打开，然后关闭快门孔。连接杆通过连接销和凸轮槽与曲柄杆连接。凸轮槽具有致动部分和保持部分。当连接销沿着致动部分移动时，连接杆的运动通过曲柄杆传递到快门叶片以打开和关闭快门孔。当连接销沿着保持部移动时，连接杆的移动不传递到快门叶片，使得快门叶片保持在打开位置。

摘要： A lens-fitted photographic film unit has an optical viewfinder whose lens elements are held at their top side by a finder lens holding plate. The finder lens holding plate extends beyond the top side of the finder lens elements and has holes for receiving upper tips of axles for pivoting a shutter actuating lever, a frame counter dial, an arresting lever and a spring for urging the shutter actuating lever in a direction against a cocked position. The finder lens holding plates also has an arched wall which contacts a peripheral surface of a cam unit including a one-tooth gear so as to rotatably support the cam unit. The one-tooth gear is engaged with teeth formed around the periphery of the frame counter dial. The engagement between the one-tooth gear and the teeth of the frame counter dial is maintained constant by virtue of the hole and the arched wall of the finder lens holding plate.
摘要翻译：带镜头的摄影胶片单元具有光学取景器，其透镜元件通过取景器透镜保持板保持在其顶侧。取景器透镜保持板延伸超过取景器透镜元件的顶侧，并且具有用于接收轴的上端的孔，用于枢转快门致动杆，框架计数器拨盘，止动杆和弹簧，用于将快门启动杆推向方向反对一个翘起的位置。取景器透镜保持板还具有拱形壁，其与包括单齿齿轮的凸轮单元的周面接触，以便可旋转地支撑凸轮单元。单齿齿轮与形成在框架台面盘周边周围的齿啮合。通过取景器透镜保持板的孔和拱形壁，单齿齿轮和框架台面盘的齿之间的啮合保持恒定。

摘要： A shutter charge device is used with photo film and charges a shutter device. The photo film includes plural groups of perforations formed along one edge thereof. The groups are arranged at the predetermined pitch of the frames. Each of the groups includes two perforations disposed closely to one another at a predetermined distance. A driven sprocket wheel is meshed intermittently with the perforations in the photo film, and rotated by a predetermined amount while the photo film is wound as long as one of the frames. A rotatable member is rotated in integral fashion with the sprocket wheel by the predetermined amount, and charges the shutter device. A retainer lever is engaged with the rotatable member rotated by the predetermined amount, and locks the sprocket wheel to block movement of the photo film. The retainer lever is disengaged from the rotatable member upon releasing of the shutter device, and unlocks the sprocket wheel to allow it to rotate. A frame counter wheel is stepped one by one when the rotatable member is rotated by the predetermined amount, and indicates a number representing exposed ones of the frames. A disabling projection is operated by winding of the photo film after creating the frames of the predetermined number, and blocks rotation of the sprocket wheel upon disengagement of the sprocket wheel from the perforations, whereby no further exposure is taken on the photo film.
摘要翻译：快门充电装置与照相胶片一起使用并对快门装置充电。摄影胶片包括沿其一个边缘形成的多组穿孔。这些组以帧的预定间距排列。每个组包括彼此以预定距离彼此紧密配置的两个穿孔。自动链轮与照相胶片中的穿孔间歇地啮合，并且当照相胶卷被卷绕成长度一个框架时旋转预定量。可旋转构件与链轮一体旋转预定量，并对快门装置充电。保持杆与可旋转的构件接合预定量，并锁定链轮以阻挡摄影胶片的移动。在释放快门装置时，保持杆与可旋转构件脱开，并且解锁链轮以允许其旋转。当可旋转构件旋转预定量时，框架计数轮一个接一个地步进，并且指示表示暴露的框架的数量。在创建预定数量的帧之后，通过卷绕照相胶片来操作禁用突起，并且在链轮与穿孔分离时阻止链轮的旋转，由此在照相胶片上不再进一步曝光。

摘要： A telephotographic optical system is incorporated into a mechanism unit with an exposure mechanism, and the mechanism unit is removably attached to a main body having a cassette chamber and a film roll chamber as an integral body. The telephotographic optical system is constituted by a telephotographic taking lens, and a pair of mirrors attached to an exposure chamber so as to conduct light entering through the taking lens along a Z-shaped light path toward an exposure aperture. A lens aperture changing mechanism is also incorporated in the mechanism unit. A switching member of the lens aperture changing mechanism is disposed on an upper wall portion of the film unit. An aperture-stop member having at least a lens aperture is moved by the switching member so as to place the lens aperture in the exposure light path. A color filter or an ND filter is inserted in the field of view of the viewfinder to indicate that the lens aperture is placed in the exposure light path, in cooperation with the aperture-stop member.
