A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.

Zoom lens barrel assembly and electronic apparatus including the same

A zoom lens barrel assembly includes: a first zoom ring comprising a first protrusion; a guide ring disposed around the first zoom ring comprising a first guide slot through which the first protrusion passes, and a second guide slot; a second zoom ring comprising a second protrusion, and movable in an axial direction; a first cylinder comprising a guide groove into which the second protrusion inserts, and a third protrusion passing through the second guide slot, and disposed between the first and second zoom rings; a second cylinder disposed around the guide ring comprising a fourth protrusion, a first groove portion into which the first protrusion inserts, and a second groove portion into which the third protrusion inserts, and supporting the first zoom ring and the first cylinder; and an external cylinder disposed around the second cylinder and comprising a third groove portion into which the fourth protrusion inserts.

A zoom lens barrel assembly includes: a zoom ring having a cylindrical shape, and comprising an inlet portion formed in a boundary of one end thereof and a first protrusion; a guide ring disposed around the zoom ring, and comprising a first guide hole through which the first protrusion passes, and movably supporting the zoom ring in an axial direction, and a second guide hole; and a cylinder disposed in the zoom ring, for moving and rotating between a position where the cylinder is accommodated in the zoom ring and a position where the cylinder moves away from the zoom ring in the axial direction, and comprising a second protrusion that passes through the second guide hole, accommodated in the inlet portion at the position where the cylinder is accommodated, and pressing one end of the inlet portion when the cylinder moves away from the zoom ring.

An opening/closing assembly for a light path and a photographing apparatus including the same, comprises: a barrier base having an opening for providing the light path; a rotatable barrier installed on the barrier base for opening/closing the light path, and including an insertion portion; a first driving member disposed on the barrier base and including a first engagement groove in which the insertion portion is inserted and a functional portion on which an external force is exerted; a second driving member disposed on the barrier base and including a second engagement groove in which the insertion portion is inserted; and an elastic member for elastically connecting the first driving member and the second driving member, wherein, when the barrier is rotated, a distance between a portion of the first engagement groove contacting the insertion portion and a portion of the second engagement groove contacting the insertion portion is varied.

Opening/closing assembly for light path and photographing apparatus including the same

A word line driver having a divided bias line in a non-volatile memory (NVM) device and method includes a row decoder for decoding a row address outputting a word line select signal to select a word line in response to the decoded result, and a bias supply unit for generating a first voltage includes a plurality of level shift circuits for shifting the first voltage in response to an externally applied program/erase signal during a first mode of operation and for outputting the shifted first voltage to the word line selected by the word line select signal, and a plurality of switching devices, which are switched in response to the program/erase signal, for transferring the word line select signal having a second voltage during a second mode of operation to the word line. This reduces the layout size of the NVM device by varying a voltage bias path and can improve an access speed during a data read mode of operation by minimizing word line delay.
