摘要： To prevent a front end of a slit forming sector of one of an open shutter sector group and a close shutter sector group from colliding with an upper edge portion of a partition opening of a partition plate and preventing leakage of light, a partition plate is provided with a partition plate opening and a projection is formed on the partition plate for preventing sector collision. The projection is formed slightly lower than the level of the upper edge portion of the partition plate opening so that immediately before a slit forming sector of the close shutter sector group comes into contact with the upper edge portion of the partition plate opening, a front end of the slit forming sector rides over the projection and is displaced from the upper edge portion of the partition plate opening. When the slit forming sector is fully closed, a lower face of the front end of the slit forming sector is separated from the projected portion and is brought into close contact with the partition plate by its own elastic force.
摘要翻译：为了防止打开的快门扇区组和闭门扇扇组之一的狭缝形成扇区的前端与分隔板的分隔开口的上边缘部分碰撞并防止光的泄漏，设置有隔板隔板开口形成在隔板上，用于防止扇区碰撞。突起形成得比分隔板开口的上边缘部分的高度略低，使得在紧闭开闭扇扇形组的狭缝形成扇区与隔板开口的上边缘部分接触之前，狭缝形成区域跨越突起并从分隔板开口的上边缘部分移位。当狭缝形成区段完全关闭时，狭缝形成区段的前端的下表面与突出部分分离，并通过其自身的弹力与隔板紧密接触。

摘要： A shutter for a camera has a film advance mechanism for advancing film past a shutter opening and a stroboscope for emitting light. The shutter has a base plate having the shutter opening, opening sectors for undergoing opening movement in an operational state to open the shutter opening during a shutter release operation, and closing sectors for undergoing closing movement in an operational state to close the shutter opening during the shutter release operation. A first detecting device detects the operational state of the opening sectors and outputs a signal to the stroboscope to emit light. A second detecting device detects the operational state of the closing sectors and outputs a signal for winding up the film. A non-opened state of the shutter opening is detected after the shutter release operation when the second detecting device detects the operational state of the closing sectors before the first detecting device detects the operational state of the opening sectors.
摘要翻译：用于相机的快门具有用于使胶片通过快门开口的前进机构和用于发光的频闪仪。闸门具有一个具有挡板开口的基板，用于在操作状态下进行打开运动的开启扇区，以在快门释放操作期间打开闸板开口，以及关闭扇区，以在操作状态下进行关闭运动，以在该操作状态期间关闭挡板开口快门释放操作。第一检测装置检测开口扇区的操作状态，并向频闪仪输出信号以发光。第二检测装置检测关闭扇区的操作状态并输出用于卷绕胶片的信号。当在第一检测装置检测到开启扇区的操作状态之前第二检测装置检测到关闭扇区的操作状态时，在快门释放操作之后检测快门打开的未打开状态。
