    • A release locking device for use in photographic cameras of the type in which an exposure meter and electromagnetic actuating and releasing means for automatic exposure control are rendered operative in separate manner by their respective control or release switches as may be operatively associated with a display button and a shutter release button respectively. This device comprises a master switch connected between an electrical power source and a common input lead of these release switches to be closed and opened in response to an actuation and a release, respectively, of a manually operable member, thereby all of the release switches are rendered effective and ineffective at a time. In a preferred embodiment, this device is operatively associated with a shutter cocking mechanism to be actuable in automatic response to a protracting movement of the shutter cocking lever into an effective range of shutter cocking operation.
    • 一种用于照相机的释放锁定装置,其中曝光计和用于自动曝光控制的电磁致动和释放装置通过它们各自的控制或释放开关以分开的方式操作,如可操作地与显示按钮相关联, 快门释放按钮。 该装置包括连接在这些释放开关的电源和公共输入引线之间的主开关,以分别响应于可手动操作的构件的致动和释放而被关闭和打开,由此所有释放开关是 一次有效和无效。 在优选实施例中,该装置可操作地与快门启动机构相关联,以便能够自动响应快门推杆的伸出运动进入快门启动操作的有效范围。
