    • A camera includes a stroke change-over member which is in first position and a second position respectively when a shutter dial is set for electric exposure control mode and for mechanical exposure control mode. The stroke change-over member, when in the first position, restricts the stroke of the movement of a mechanical release initiating member and, when in the second position, allows the movement of the mechanical release initiating member beyond the restricted stroke, the movement being caused by depression of a shutter button. The camera further includes an electromagnetic release initiating member movable from a first to a second position in response to the depression of the shutter button and a locking member for locking the electromagnetic release initiating member at the first position when the shutter dial is set for mechanical exposure control. The electromagnetic release initiating member allows an electromagnetic release device to release the shutter mechanism when moved a short distance before the movement of the mechanical release initiating member is restricted by the stroke change-over member. The mechanical release initiating member, when moved beyond the restricted stroke, serves to retain the locking of a winding member by another locking member, thereby preventing accidental winding of a film and charging of the shutter mechanism with the shutter button kept depressed as well as allows a mechanical release device to release the shutter mechanism.
    • 相机包括当为曝光控制模式设置快门拨盘并且用于机械曝光控制模式时分别位于第一位置和第二位置的行程转换部件。 当处于第一位置时,行程转换构件限制机械释放起动构件的运动的行程,并且当处于第二位置时,允许机械释放起动构件的运动超出限制冲程,运动是 由按下快门按钮引起的。 照相机还包括电磁释放启动构件,其响应于快门按钮的按下而可从第一位置移动到第二位置;以及锁定构件,用于当快门拨盘被设置用于机械曝光时将电磁释放启动构件锁定在第一位置 控制。 电磁释放引发构件允许电磁释放装置在机械释放引发构件的移动被行程转换构件限制之前移动短距离时释放快门机构。 机械释放启动构件当移动超过受限制的行程时,用于通过另一个锁定构件保持卷绕构件的锁定,从而防止膜的意外卷绕并且快门按钮被保持按压而使快门机构充电以及允许 用于释放快门机构的机械释放装置。

    • A camera has a cavity for receiving a self-processing film cassette and includes an automatic exposure control circuit and a flash device which are provided with energizing contacts located in the cassette receiving cavity. The film cassette houses a battery connected to contacts mounted on the cassette and engaging the cavity contacts when the cassette is received in the cavity. The exposure circuit responds to a photosensitive element exposed to the objective traversing light reflected by the film at the objective focal plane. The camera includes a synchronous switch whose closing position responds to the focussing of the objective lens.
    • 相机具有用于接收自动处理胶片暗盒的空腔,并且包括设置有位于盒接收腔中的激励触点的自动曝光控制电路和闪光灯装置。 当盒子被容纳在空腔中时,胶片盒装有连接到安装在盒上的接触件的电池并与空腔接触件接合。 曝光电路响应于在物镜焦平面处暴露于物镜穿过由光反射的光的感光元件。 摄像机包括同步开关,其闭合位置响应于物镜的聚焦。

    • In an image pickup device of the present invention, in the case where a mode switch 116 selects a finder mode, a focusing lens is driven at a first speed when a focusing operation is performed in a focus control unit 203. In the case where the mode switch 116 selects a live view mode, the driving speed of the focusing lens is switched in a range lower than the first speed in accordance with brightness of an object detected by a photometric unit 114 when the focusing operation is performed in the focus control unit 203. With such a configuration, a lens driving control method is changed by AF control of a phase difference detection system and AF control of a hill climbing system, and a driving system suitable for each AF system is performed, whereby the focusing operation can be performed normally at a high speed.
    • 在本发明的图像拾取装置中,在模式开关116选择取景器模式的情况下,当在聚焦控制单元203中进行聚焦操作时,以第一速度驱动聚焦透镜。在 模式开关116选择实时取景模式,当在聚焦控制单元中执行聚焦操作时,根据由测光单元114检测到的物体的亮度,聚焦透镜的驱动速度被切换到低于第一速度的范围内 通过这样的结构,通过相位差检测系统的AF控制和爬坡系统的AF控制来改变透镜驱动控制方法,并且执行适合于每个AF系统的驱动系统,由此聚焦操作可以 以高速正常进行。
