发明名称 INTERLOCKING DEVICE FOR THE EXPOSURE METER IN A CAMERA
摘要 An interlocking device for the exposure meter in a camera includes a rotatable interlocking member engaging an exposure regulating member, a locking lever pivotally mounted on the interlocking member for rotation with the interlocking member, a needle scanning member engageable with the interlocking member and movable in response to the rotation of the interlocking member and the locking lever to scan the position of the needle of the exposure meter, and a fixed locking member. The locking lever is moved with respect to the interlocking member by the movement of the latter when the scanning member is stopped, and that movement of the locking lever is imparted to the fixed locking member without exerting any great force upon the needle of the photoexposure meter. Another embodiment further provides means to make the movement substantially linear of the lever which is moved by the exposure control interlocking pin provided at the lens. Moreover, means are provided for reducing the gap between the needle of the exposure meter and the stepped portion of the interlocking lever before exposure adjustment.
