20100208365 | LENS BARREL - A barrier unit which can be easily assembled to a lens holding member in view of the above problems. The direction in which a barrier unit is rotated when the barrier unit is assembled with a lens holding member coincides with the direction in which a barrier blade driving member is rotated when the barrier blade is closed from the open state. | 08-19-2010 |
20100209088 | LENS BARREL AND IMAGE PICKUP APPARATUS - A lens barrel capable of reducing the radial size thereof while maintaining the degree of freedom in layout of a shutter and a anti-shake mechanism. A barrier drive ring includes first and second rotation-transmitting protrusions axially protruding toward an imaging area and parallel to and substantially opposed to each other. An image pickup element-holding member includes a first and second cam contact section which are brought into contact with the first and second rotation-transmitting protrusion, when the lens barrel is retracted. Rotation transmission to the barrier drive ring is performed in a varying manner first via a contact between the first rotation-transmitting protrusion and first cam contact section, then via contacts between the first and second rotation-transmitting protrusions and the first and second cam contact sections, and finally via a contact between the second rotation-transmitting protrusion and the second cam contact section. | 08-19-2010 |
20100284097 | OPTICAL APPARATUS AND IMAGE PICKUP APPARATUS PROVIDED WITH THE OPTICAL APPARATUS - Provided is an optical apparatus including: two magnets which are constituent components of drive member for moving a lens holder ( | 11-11-2010 |
20110188842 | IMAGING APPARATUS - An imaging apparatus is provided with a lens barrel that includes a flexible substrate that is electrically connected to a magnetically driven apparatus and drive ring that drives the lens barrel by rotating. The drive rings include through grooves that pass through the drive ring and a flexible substrate passes therethrough from the inside to the outside of the lens barrel and a strobe cam that is provided on the outer circumferential side of the drive ring. In addition, the through groove and the strobe cam are disposed so as to coincide in the rotation direction of the drive ring. | 08-04-2011 |
20110194193 | IMAGING APPARATUS - An imaging apparatus has in a first cam groove a first cam surface whose lead is lying with respect to the rotating direction of a drive ring, and a second cam surface whose lead is steep with respect to the rotating direction of the drive ring, and when transition is effected from an accommodated state to a use state, a follower member passes the first cam surface, and when transition is effected from the state where the follower member is engaged with a second cam groove to the accommodated state, the follower member passes the second cam surface. | 08-11-2011 |

20150036227 | OPTICAL DEVICE HAVING IMPROVED IMPACT RESISTANCE - An optical device whose impact resistance against an impact improved without increasing the size thereof. A first-group lens barrel holds has radially protruding follower pins formed thereon. A cam ring is disposed outside the first-group lens barrel, and has cam grooves formed therein for engagement with the follower pins. A diaphragm unit disposed rearward of the first-group lens barrel and a second-group lens barrel disposed rearward of the diaphragm unit move in the optical axis direction. When the diaphragm unit and the second-group lens barrel move in the optical axis direction, the optical device is switched between a wide angle position in which first protrusions formed on the diaphragm unit are positioned inside the follower pins and a telephoto position in which third protrusions formed on the second-group lens barrel are positioned inside the same. | 02-05-2015 |
20150043090 | OPTICAL DEVICE PROVIDED WITH ZOOMING MECHANISM - An optical device, such as a lens or a light quantity adjusting member, which, even in a specification with a long extension stroke thereof, can avoid an increase in the size of the optical device and can also reduce the start-up time without damaging components in the optical device. An extracting section, a convex section, and a concave section are formed in a fixing member side by side in an optical axis direction. A flexible board is extracted from the extracting section. The convex section is located on an image surface side of the extracting section and formed to project to an inner diameter side from the extracting section. The concave section is located on an image surface side of the convex section and formed to be recessed to an outer diameter side of the extracting section. While the optical device is shifting into an accommodated state, the flexible board is brought into contact with at least a part of the convex section, and a first bending portion of the flexible board is made to project to an inner diameter side thereof, and the second bending portion of the flexible board is accommodated in the concave section. | 02-12-2015 |
