Complete Description of the Invention In the following detailed description, for the purposes of explanation, a number of specific details are put forward to provide a comprehensive understanding of the manifestations of the expressed embodiment. However, it will be clear that one or more embodiments can be practiced without details this specific. In other examples, the structures and well known tools are schematically shown for simplify the image. This disclosure provides an imaging lens module which includes a variable aperture module and a lens imaging. The variable aperture module and the imaging lens sequentially placed along an optical axis from One side of the object to one side of the image. The variable aperture module includes a blade assembly, a positioning element, a driving member and a number of suppressor structure. The blade assembly includes a number of blades that can be movable which is placed around the optical axis to form A hole through which light can pass with a certain size. can be adjusted for different hole size conditions. In addition, light enters the imaging lens through a hole that light can pass through from the variable aperture module. Each movable blade has a hole positioning and a movement hole adjacent to the the positioning hole. These positioning elements include a number of structures successively placed positions correspond with positioning holes of a number of blades that can be moved so as to position a number of blades that can moved. In addition, each positioning structure can be in the form of a structure of positioning elements that extend along along a direction parallel to the optical axis. With design the positioning structure as a structure that protruding upwards or downwards, is profitable to accurately control the size of the holes that can be drilled passed by light. The driving part includes a rotational element. The rotation elements may include a number of rotation structures. which can be placed in a row according to movement holes of a plurality of movable blades and can be moved in each of the movement holes. The rotation element can be rotated with respect to the element positioning so as to move the movable blades to rotate about the positioning structures of the elements positioning to adjust the size of the hole that can be passed through by light. In addition, each rotational structure can in the form of a structure of rotating elements that extend in along a direction parallel to the optical axis. Therefore Therefore, it is advantageous to accurately control the size from a hole through which light can pass. On each of the movable blades, one structure the pressure is placed in at least one of the positioning hole and movement hole of the adjustable blade moved, and at least presses on at least one of the of the positioning structure and rotation elements. In addition, on each movable blade, the pressing structure of which corresponding can be placed on one side of the hole positioning or one side of the movement hole. By therefore, it is beneficial to increase stability manufacturing. In addition, each movable blade may further have an inner surface and a the outer surface of the movement hole from it, the surface the inner part can be located closer to the hole positioning of the outer surface, and the pressure structure the corresponding one can be placed on at least one of the inner surface and outer surface. Therefore, it is advantageous to determine the position of the suppressor structure which depends on the convenience of manufacture thus increasing production efficiency. Alternatively, on each blade movable, the corresponding pressing structure can circumferentially placed in the positioning hole or holes movement. Therefore, it is beneficial to increase the stability of the overall structure. In addition, movable blades and pressing structures respectively the corresponding ones placed on it can be made in one part. Therefore, it is beneficial to simplify the assembly process thereby increasing efficiency production. With the arrangement of suppressive structures, it is beneficial to reduce backlash between movable blades and positioning structures or between the movable blades and the rotating elements and thus accurately control the positions of movable blades, thereby reducing effect caused by the hysteresis of the blades can be moved and reduces the difference in aperture size between actual value and theoretical value. In addition, by placing rotational structures to fit the holes the movement of the movable blades, is advantageous to further accurately control the size from a hole through which light can pass. Each of the movable blades can include A first surface layer, a second surface layer and An inner substrate layer. An inner substrate layer can be located between the first surface layer and second surface layer. By designing blades that can driven in the form of composite materials, is advantageous to meet the requirements for thinness manufacturing. In addition, on movable blades respectively, surface layer The first and second surface layers can be located further closer to the center of the hole than light can pass through inner substrate layer. By designing blades that can driven as a multi-layer structure, is beneficial to reduce reflection from diffused light. Please referring to Figure 12 and Figure 13, which show the blades that movable (211) according to the 2nd embodiment of the disclosure this, where the inner substrate layer (2115) is located between the first surface layer (2113) and the surface layer second (2114), and first surface layer (2113) and layer the second surface (2114) is located closer to the center (CT) from holes through which light can pass (HL) rather than layers inner substrate (2115). The drive section may further include a a magnet and a coil. The magnet and coil can placed in relation to each other, and one of The magnets and coils can be placed on the rotating element. Therefore, the interaction force produced by the magnet and The coil is advantageous for driving rotating elements to move against the positioning element. The drive section may further include a base. The rotation elements can be placed on the base along a direction parallel to the optical axis. The supporting force provided by the base is sufficient. to support the rotating elements and therefore is beneficial to secure the structural strength of the module variable aperture and achieve mass production conditions. The drive parts may further include at least two bearing components that can be placed either in between rotation elements and positioning elements or between elements rotation and base along a direction parallel to the optical axis so as to support the rotational movement of the element rotation. Therefore, it is beneficial to increase stability of the rotational motion of the rotating elements. In addition, The number of bearing components can be five or less. Therefore, it is profitable to maintain the rate manufacturing results. In addition, each bearing component can spherical, and all bearing components can be aligned on the same plane to the optical axis. Therefore, it is profitable to further secure the stability of rotational movement of the rotating element. Each bearing component can have a number of points of contact that can be in physical contact with rotational elements, positioning elements or bases. Contact points it can have an internal contact point, a outer contact point, a top contact point and a point bottom contact. The inner contact point can be located closer to the optical axis than the other contact points. The outer contact point can be located further away. from the optical axis than the other contact points. Contact points The above can be one of two points of contact the furthest distance from each other in a direction parallel to the optical axis between all contact points. the bottom contact can be either of the two the points of contact that are the furthest apart from each other in a given direction which is parallel to the optical axis between all contact points. With the arrangement of contact points, it is advantageous to perform good alignment between rotation elements and elements positioning or between the rotation and base elements so that maintain its positions during rotational movements of the rotation elements. Specifically, the alignment through the point inner contact and outer contact points help to maintain good radial positions between rotational elements and positioning elements or between rotation and base elements, and alignment through the upper contact point and the lower contact point helps to maintain good axial positions between rotation elements and positioning elements or between rotation elements and base. In addition, the number of all contact points can be four. Alternatively, the number of all contact points can be three. When the sum of all contact points is three, one of inner contact point and outer contact point and wrong one of the top contact points and the bottom contact point between all the contact point can be the same contact point. When a distance perpendicular to the optical axis is between the inner contact point and the outer contact point is Dt, and a distance perpendicular to the optical axis between the inner contact point and the remaining contact points among all the contact points is Di, the following conditions can be fulfilled: 0.3 S Di / Dt S 0.7. Therefore, it is profitable to balance the forces applied to the rotating elements thus ensuring the dynamic stability of the elements during rotational movement of the rotating element. Please note that the definition of “remaining contact point” on Di is the point bottom contact when the sum of all contact points is four, the definition of “remaining contact points” in Di is a contact points instead of the inner contact points and the above mentioned external parts, which can be contact points top or bottom contact point, when the sum of all contact points is three.
