Brother and [previous technology] Press, the shutter mechanism of the camera is above the three-caliber diameter, the mechanism can be roughly divided into one drive source, two drive sources and three drive sources, etc., a single 'drive source mode The mechanism includes a caliber mechanism and a shutter opening and closing mechanism, and the caliber mechanism is driven by a ratchet method, and the __ mechanism is provided in a manner of closing the connecting rod and the fixed connecting rod, and the spring is used to make the shutter quickly close. The __ stepping motor (StepMQto) activates the stepping area range by the H-axis tree axis in a certain mechanism position in the mechanism, and activates the ratchet mechanism of the caliber switching or the stopping mechanism of the opening and closing of the caliber to complete the caliber switching. Or the action of opening and closing, the advantages of this mechanism are mainly low cost of parts, small electrical influence, and the speed of the shutter is tender and tender, and the coffee is twisted; the chest is "small, the shutter mechanism is large, noisy, and the ground is clear. The speed is slow and the degree of freedom of the aperture switching is low. The two-in-one axis of the shaft is __touch, and its function is to drive the caliber to switch the feather root for the caliber switching mechanism, to directly open and close the feather root, and to open and close the J mechanism. The low cost and the diameter change of the two 'electrical influences And the shutter speed change degree of freedom 5 two or more job source modes are three or more solenoid valve motors (Im M enemy) to separate the dynamic caliber and timely cut display, its electromagnetic motor Drive the caliber opening and closing, the other solenoid valve motors are used as the driving source for the caliber switching. One characteristic of this mechanism is that the driving source directly links the feathers, and there is no other connecting rod for the connection driving. The main disadvantage of this type of mechanism is that the more the number of solenoid valves it uses, the more the number of solenoid valve motors it uses, which will result in a costly product that is more complicated. In addition, if there is a dimming mirror (10) FIL dish in the shutter, the driving source must be two to three driving sources. The disadvantages are that the caliber is slow, the shutter precision is susceptible to electrical influence, the shape is increased, and the cost is increased. . The conventional shutter mechanism (4) plus-dimmering configuration has two main types - the type is independent _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Due to the addition of a driving source, the cost is greatly increased and the appearance of the shutter mechanism is significantly increased.
