Embodiment Construction

[0025] The shutter mechanism of the present invention includes a base 1, a light reducing mirror 2, a connecting rod device, a bore cam ring 4, a stepping motor 51, a solenoid valve motor 52, a connecting rod cover 6, a shutter feather 7, a feather partition 8, and a bore feather 9 and feather cover 90. The base 1 is generally in the shape of a disk, with a first surface 10 and a second surface 100 (see Fig. 2B and Fig. 3 ), and its middle part is provided with a central light hole 101 penetrating through the first and second surfaces, and the first surface 10 A motor seat 11 is provided at one side edge of the motor for receiving the stepper motor 51 . On the edge of the first surface 10 opposite to the motor seat 11 is a solenoid valve seat 12 , on which a solenoid valve support 104 is arranged for receiving and fixing the solenoid valve motor 52 . The first surface 10 is provided with a central ring wall 102 surrounding the central light hole 101 for arranging the aperture...

Abstract

This invention discloses one camera shot structure, which comprises base socket, radium protruding ring, connection bar device, step motor, short base and caliber base, wherein, reverse clock needle of the caliber ring rotates or does clockwise to separately control the caliber switch operation and shot base switch; it adopts electromagnetic motor fix caliber to drive light damper lens to make it cover or leave light ring.

Description

【Technical field】 [0001] The invention relates to a shutter mechanism for a camera, in particular to a shutter mechanism for a camera which includes a light reduction mirror and is controlled by one mechanism to switch apertures and open and close the shutter. 【Background technique】 [0002] If the shutter mechanism of the camera has more than three apertures, its mechanism can be roughly divided into different modes such as one driving source, two driving sources and three driving sources, among which the mechanism of single driving source includes aperture mechanism and shutter opening and closing. The mechanism drives the aperture mechanism with a ratchet, drives the aperture opening and closing mechanism with an opening and closing link and a fixed link, and uses a spring to make the shutter close quickly. It uses a stepping motor (Step Motor) in the mechanism to use a certain mechanism position as a reference to distinguish the range of actuation stepping ranges for out...
