    • A film feeding device for a camera including a rotatable center shaft member having a protrudent clutch pin, the center shaft being movable alone in the direction of its axis; a rotatable film feeding sprocket which has a slot to allow the protrudent pin to engage therewith and which thus moves together with the center shaft member when the center shaft rotates; a drive device which is provided with a clutch groove to allow the protrudent pin to engage with and disengage from the clutch groove, the drive device being arranged to rotate in response to a film winding operation. When the center shaft shifts to one side defined by the slot, the protrudent clutch pin comes to engage with the clutch groove to cause the sprocket to rotate in response to the film winding operation. When the center shaft shifts to the other side, the protrudent clutch pin is disengaged from the clutch groove to permit free rotation of the sprocket. Thus, rotation of the sprocket is controlled by means of the single protrudent pin in such a manner as to minimize variation in spacing between one photographed picture and another.
    • 一种用于照相机的胶片馈送装置,包括具有突出离合器销的可旋转的中心轴构件,所述中心轴可在其轴线方向上单独移动; 可旋转的胶片馈送链轮,其具有槽,以允许突出销与其接合,并且随着中心轴旋转时与该中心轴构件一起移动; 驱动装置,其设置有离合器槽以允许突出销与离合器槽接合和分离,驱动装置被布置成响应于膜卷绕操作而旋转。 当中心轴移动到由狭槽限定的一侧时,突出离合器销与离合器槽接合,以使得链轮响应于膜卷绕操作而旋转。 当中心轴移动到另一侧时,突出离合器销与离合器槽脱离,以允许链轮自由旋转。 因此,通过单个突出销来控制链轮的旋转,使得最小化一个拍摄图像与另一个拍摄图像之间的间隔的变化。

    • In a circumstance in which light is emitted from many electronic flashes, e.g., a press conference hall or a wedding hall, light emission from other electronic flashes overlaps preliminary light emission performed before main light emission. This decreases the photometry accuracy with respect to preliminary light emission and makes it difficult to perform proper flash exposure. In a camera system designed to perform preliminary light emission before main light emission, photometry is performed a plurality of number of times upon preliminary light emission, and flash exposure is performed by suppressing photometric values which may have been influenced by light emission as disturbance other than the preliminary light emission.
    • 在许多电子闪光灯例如记者会议厅或婚礼大厅发出光的情况下,来自其他电子闪光灯的发光与在主发光之前进行的初步发光重叠。 相对于初步发光,这降低了测光精度,并且难以进行适当的闪光曝光。 在被设计为在主发光之前进行初步发光的照相机系统中,在初步发光时进行多次光度测定,并且通过抑制可能受光发射影响的光度值而进行闪光曝光,作为除了 初步发光。
