PURPOSE:To stabilize the operation speed of a high-speed operating member of the camera, by providing a governing means which is fitted eccentrically to a shaft driven by a governing gear train and damps the rotation of the shaft at a rotation time by an eccentric shake motion. CONSTITUTION:A governing mechanism including a governing gear train accelerated and driven synchronously by a driving member, which drives a high- speed operating shutter to a prescribed position, is connected to this driving member, and an eccentric part 29 is formed in the boss part of a stop wheel 21, which is driven by the last gear 20a of this gear train, as one body, and a governor 31 provided with a round hole 30 to be fitted to this eccentric part 29 is provided and when a boss 28 of the stop wheel is rotated at 90 deg., the governor 31 is shaked and moved from the position indicated by the solid line to the position indicated by the broken line, and leveled damping force is obtained, and thus, the speed of the driving member for shutter driving or the like is kept constant. |
