A lens position detecting devicehas a position detecting magnet, a magnetic force detecting sensor, a positional information generating means, etc. The position detecting magnetis mounted on a rear surface of a lens holder frame. The magnetic force detecting sensorserves to generate a detected signal having a magnitude depending on the intensity of a magnetic force generated from the magnetic poles of the position detecting magnet. The magnetic force detecting sensoris disposed on a straight line that passes through the position detecting magnetparallel to the optical axis. The magnetic force detecting sensoroutputs a detected signal having a voltage corresponding (proportional) to the intensity of the magnetic force. An amplifying circuitof a positional information generating meansamplifies the detected signal Ss from the magnetic force detecting sensor

Lens position detecting device including a position detecting magnet and a magnet force detecting sensor

A image blur correcting mechanism for effecting image blur correction by moving a lens group in directions orthogonal to an optical axis of the lens group, includes a first guide shaft extending in a first direction which is a predetermined direction orthogonal to an optical axis direction of the lens group, a base frame supporting the first guide shaft, a first correcting moving frame supported by the base frame through the first guide shaft movably in the first direction, a second guide shaft extending in a second direction orthogonal to both of the optical axis direction and the first direction and supported by the first correcting moving frame, and a second correcting moving frame having a lens holding part holding the lens group, the second correcting moving frame being supported by the first correcting moving frame through the second guide shaft movably in the second direction, while being movable in the first direction along movement of the first correcting moving frame with respect to the base frame in the first direction.

Image blur correcting mechanism and image-capture apparatus

A main flexible substrate has a mount surface portion to be mounted to the rear surface of a base, and a movable surface portion extended from the mount surface portion. At a portion of the movable surface portion near the mount surface portion, there is provided an undulatable surface portion undulatable between a bent state of being bent relative to the mount surface portion and separate from the rear surface of the base and a flat state of being mated and mounted to the rear surface of the base. A first soldered terminal portion is formed on the front surface of the undulatable surface portion. A base end portion of a shutter flexible substrate extended to the rear side of the rear surface of the base and a base end portion of a coil flexible substrate are each provided with a second soldered terminal portion.

Lens-barrel and image pickup apparatus

A lens barrel has a base, a second lens holder frame holding a second lens group, a first lens holder frame holding a first lens group, a cam ring, and a fixed ring. The second lens holder frame has three guides projecting axially from an outer circumferential portion of an annular plate and disposed at circumferentially equally spaced intervals. Guide grooves are defined in respective portions of the annular plate which are radially inwardly faced by the guides. Guide posts engage respectively in the guide grooves, so that the second lens holder frame is nonrotatably, but axially movably supported by the guide posts.
