Patent number: 10649318Abstract: A monitoring camera which has a lock mechanism, which is capable to unlock a lens 1 even if power supply is stopped due to blackout. The lock mechanism includes a lock member 11 having a region 11b which is pushed by an operation member 3 in a state where a lock pin member 12 engages with the lens 1, a biasing member 13 biasing the lock member 11, and magnetic force generating units 10 generating magnetic forces by electro energization, to move against the biasing force so that the region 11c faces the operation member 3. While the magnetic forces are not generated in a non-electro energization state, the operation member 3 pushes the region 11b and thus moves the lock member 11 and the lock pin member 12 so that the lock pin member 12 is released from the lens 1.Type: GrantFiled: January 16, 2019Date of Patent: May 12, 2020Assignee: CANON KABUSHIKI KAISHAInventor: Ryuichi Nagae

Patent number: 7808728Abstract: A lens barrel that can be reduced in size and improve drive accuracy. A first cylindrical member is fixed. A rotatable second cylindrical member cam-engages with the first cylindrical member so as to move in an axial direction of an axial center. A third cylindrical member engaging with the first cylindrical member so as not to rotate can move in the axial direction by the rotation of the second cylindrical member. A fourth cylindrical member cam-engaging with the third cylindrical member engages with the second cylindrical member so as to move in the axial direction by following the rotation of the second cylindrical member. A lens holding member engaging with the third cylindrical member so as not to rotate relative to the third cylindrical member can move in the axial direction by cam-engaging with the fourth cylindrical member.Type: GrantFiled: June 30, 2009Date of Patent: October 5, 2010Assignee: Canon Kabushiki KaishaInventor: Ryuichi Nagae
